I've been making excessive amounts of bread.
(We intend to get rid of pagination once the next implementation of Arc is ready.)

Hopefully, this will reduce the use of virgin plastic for creating art pieces in 3d printing community and you might be able to create beautiful and useful things out of waste plastic while cleaning plastic waste from the environment.
It's a profitable business.
I worked on this in my free time during quarantine.
I want to make the project more accessible so people around the world can develop local recycling unit. There is lots of work which needs to be done including making parts more standardized, demonstrating how parts fight together in a visual way and also have a microcontroller firmware to control diameter of filament. I don't have much experience with microcontrollers but I've ideas, so we'll see.
I'm thinking about making the extension intercept the traffic to the website of my favorite delivery services and automatically place the call so the button click also won't be required.
We were in the same office and needed a fast, simple way to communicate with eachother without coming in close contact (covid 19) and wanted to do that over LAN rather than use tools over the internet NOR use our ancient intercom system. So now we are using this internally for fast file sharing and good quality video calls.
Going to be introducing group calls soon and also the ability to integrate online calling and file sharing.

I've built this tool because satellite imagery can be extremely beautiful [2], and I was looking for a way of regularly receiving high-resolution satellite views of arbitrary locations such as the center pivot irrigation farms of the American heartland [3] in my timeline. Plus, for obvious reasons, it's nice to see the world without actually having to go outside right now.
Currently, I'm running two Twitter bots based on ærialbot:
* @americasquared, which posts one randomly selected square mile of the United States every 4 hours: https://twitter.com/americasquared
* @placesfromorbit, which analogously posts a 5×5 km square anywhere in the world every 6 hours: https://twitter.com/placesfromorbit

I finally put my photos up on my personal website. The only constraint I gave myself was to build a site that doesn’t need Javascript to load.
In the end I ended up using Next.js as a static site generator that pulls all the routes from my directory structure, making it possible to add new photography collections and filters as I go.
Might be overkill for the use case but it was fun to learn. The irony is I had to write a bunch of JS to produce it.
Still need to optimize the image sizes and I am thinking about adding filters for b&w/color/format.

I've tried to make it intuitive enough that you don't have to read a page of instructions first but let me know if I've missed the mark. I'm hoping you can learn the gameplay mechanics as you play.
I'm not using any web frameworks for this which was actually fun to do. It gave me a chance to improve my understanding of CSS animations + reflows, and catch up with changes to JavaScript.
1) Trail Router (https://trailrouter.com) - This is a running route planner that favours greenery and nature in the routes it generates. It can generate point-to-point or round-trip routes that meet a specified distance. I developed this because I am (or was...) a frequent traveller for work, and want to run in nice areas rather than by horrible busy roads when I'm visiting somewhere new. Naturally, the utility of this tool is limited at the moment for people stuck in lockdown!
2) Fresh Brews (https://twitter.com/FreshBrews_UK) - I've been touring the UK's finest craft beer breweries from my own home in recent weeks. New beer releases sell out very quickly and I was frequently missing out. Fresh Brews is a simple bot that monitors the online shops of my favourite breweries and posts when a new beer is released to the shop, or an item comes back into stock.
It is an electron (toolbar) app, which uses WebRTC, so should be fully P2P.
It is too early to use or show, but I did not want to miss out on this thread!
It's sort of starting to make the transition between a pile of ideas and an actually useful tool at the moment. The whole idea is to be a vector editing application that works more like a bitmap tool when it comes to painting, so there's a flood-fill tool and a way to build up paths just by drawing on the canvas rather than having to manually mess around with control points.
The way I built the UI is unique too I think. Choices for UI librarys for Rust were quite limited when I started so I built it to be easy to move to different libraries. I don't think there's any other UI library in existence that is as seamless for switching between platforms (or which can turn from a native app to a web app with a compiler flag without resorting to something like Electron)
A major issue that I've seen is that of most beginner-focused educational content not being fast enough to learn with for the more experienced developer. This along with the fact that time is often a big issue for us. I've had numerous times where I had to learn a new framework within a 1-2 week time span in order to plug some work gap or speed up a project, and found no legitimate resources that could allow an intermediate developer like me to learn faster.
This is why I am currently creating content targeted specifically at intermediate to advanced developers and teaching new languages and frameworks (using the 'constructivist' method) in a way that makes the process of learning them much more efficient. In short, faster.
It's a little rough around the edges but you can check out the blog where I share my current tutorials here: https://fromtoschool.com.
To gain a better understanding of why the method of teaching that I've described is more efficient than others for the intermediate developer, check out this post: https://fromtoschool.com/why-most-programming-tutorials-are-....
Frustrated by filter bubbles and the general state of online debate, especially on Twitter, I made Debubble.
It’s a publishing tool that will let you challenge another Twitter user to a debate. If they accept, the two of you will be able to engage in a public but distraction-free conversation. Debubble will make sure you wait for your turn before you can deliver your arguments. It will also limit each response to 1500 characters (roughly one page) and the entire debate to 12 turns. Instead of cheering for their side like sports fans, registered readers will be able to signal the value they got from your conversation by starring the whole debate.
I haven’t properly tried to launch it yet, as my day job and kids are keeping me very busy at the moment.
The general plan is to use about 400 pounds of lithium iron phosphate cells, spread between the spaces under the right and left rear passenger seats where the gas tank used to be and the engine compartment (mostly approximately where the radiator was). I'm using a Netgain Hyper9 AC motor (144 volt version). I haven't decided what I'll do for charging and battery management. I plan to order an adapter from CanEV to interface to the transmission so I'll be able to keep the stickshift.
When you are accustomed to how things work and then forced to change its not fun. Current covid19 circumstances brought enough unwanted changes. This project started out as a fuck you to MS but it really turned into a fun project to keep my productively on track and also keep my mind busy.
The only shame is that I can't really "release" this cause it really looks like the original and the copyright vultures will waste no time coming for me. My best bet would be to change the UI design. BUT that would void the original purpose of the project.

We're working with other local maker-y spaces on these efforts; we've picked up a few Ender 3's to help with the 3D printing and we have a small team of volunteers helping with sewing. So far we've distributed over 1,500 face masks to folks and healthcare workers in Fresno, San Diego, Idaho, and soon to a school in Uganda.
This is all on top of trying to keep our community engaged and hosting meetups and happy hours on Zoom. Also on top of my day job. I've never been so busy in my life, and I'm looking forward to a time when we can safely re-open and get back to building the community face-to-face.

I'm a keen mountain biker, so I've put my energy and frustration into developing new mountain bike trails in the hills around my house. Been meaning to do this for a long time, but there are such good trails a few miles further away, so the incentive has not been very strong until now.
I'm building for about 1 hour per day on average, and I manage to get between 10 and 100m of trail built in that hour, so by the time the lock-down ends I'm aiming to have a contiguous piece of singletrack that's a mile long.
Also, I've been helping on a local project to develop an open-source ventilator (https://www.backabuddy.co.za/champion/project/rescuevent)
And I'm working on a peer-to-peer donation platform (which is not really ready to show to anyone yet)
I've been a musician for going on 20 years, mainly piano but I like to collect the ability to noodle on instruments. When I was around 13 I broke my left forearm and it healed in a way that limits the rotation of my wrist quite a bit. This makes playing guitar rather difficult and at the time I started to consider branching out from piano there were a bunch of factors that made me give up on being able to play guitar. I was gigging as a piano player for 10-12 hours a week, while also going to school for piano and CS I started to develop tendonitis and trying to play guitar made it a lot worse, so I quit. I'm now in a place where I can take care of my arm (and I have actual healthcare) so I started back up again.
I guess HN is cool with self-promotion, so here's a jam I made with a looper pedal after about 2 weeks. I call it "More Theory Than Experience"
http://pointillism.digitalbunker.dev/: I've always been into generative art, so I built this site that takes a source image and recreates it in a Pointillism style
http://gitrandom.digitalbunker.dev/ : Generally when I'm struggling to come up with project ideas, I'll just browse GitHub. This site lets you explore random GitHub projects by language and topic.
I built the sites using Vapor, so I could continue to use Swift and just learn one new thing at a time.
I'm probably going to pick up some iOS app too to leverage the new hobbies people are discovering being at home (i.e. bread making).
I was looking for a Zettelkasten note taking app which would 1. work on laptop and phone 2. wouldn't have any vendor lock-in and 3. wouldn't go away if a single company folded - couldn't find one, so I started writing one. I'm writing it as a PWA to make it available ~everywhere and planning to use dropbox/google drive/whichever as the backend so users will have full control over their notes.
I'm amazed how much you can accomplish with modern web tech stack. I can literally bypass any need for a server by having the user connect to their cloud! I can just create a PWA and publish it as an app! On the downside I've learned that some features are hard to implement with above requirements using PWAs though. For example, only Chrome supports some level of filesystem access, so storing notes locally would mean discriminating by browser, which I don't feel great about.
Real-time avatars with our deep computer vision pipeline; developed with GStreamer, Rust and LibTorch. This CV pipeline is usually used for training robots inside simulations and generating synthetic datasets. But given the circumstances, thought it would be fun to explore other use cases.
It's a RESTful server-side API for adding user authentication and authorization flows to your apps.
We've been taking a lot of inspiration from Stripe and mostly just wanted to use an auth service with docs like Stripe :)
(Please note this is still pre-pre-pre beta. The docs are incomplete and we have yet to even integrate it with our own apps, so please don't try to build an app with it yet!)
It's a nice mix of both online and offline work. Also, the community around here is mostly made up of various combinations of farmers, hippies, retirees, and permaculture folks. Everyone wants a decent internet connection, but no one really has the skills to do much about it. I've lived here a year now, so thought I'd give it a go.
It's a windy road. Actually, it all started out because I wanted to get fast internet for myself on my farm. Then I thought, "Hey, why not start a business?" Feature creep at its best.
So far I have a camera working that can sleep when no motion and wake back up if low battery after enough charge.
Because of the distance we are from each other, our friendship has relied heavily on phone calls and video calls. Some time ago, we started calling them, "remote coffees", "- Hey man, when are we having our next remote coffee?"
We met at the University, we spent about two years working for the same company and we have kept in touch during these years thanks to our "remotte coffees" and also due to the many concerns about technology and productivity we have in common. "This conversation should have been recorded!". We are sure this same thought came to you after some either formal or informal conversation you had. The challenge was simply to place a product live with as much free time as this quarantine allows, and here it is. We are not launching a super business, nor did we intend to, we both are fully dedicated to something else. We just wanted to launch this MPV and share it with friends and contacts.
We do have a lot more functionalities and ideas to put on it but, if you want to try it, those ideas will be much better by taking into account your honest feedback.
Decided to open source some of the personal projects of mine. https://github.com/vivekhub/password-generator and https://github.com/vivekhub/simplenote-backup. Nothing fancy but something I have been meaning to do and started doing it. Started learning K8S as well so that is a positive. Decided to setup a personal website https://www.vivekv.info as well and had to learn hugo to do that. So on the whole feeling good. Sorry about all the links and plugs but hey I am genuinely proud of what I have done :-)
- Web geo APIs to guide you to the next "treasure".
- Webcam API to capture matching photo.
- "AI" for matching photos and answers to questions in the backend.
- the "AI" doesn't work well, planning to add a python Lambda with a better SSIM algo.
The hardest part so far has been permissions in iOS. If the user blocked geo permissions for Safari it is kind of a pain to enable again for a normal user. I haven't had a chance to test in Android yet but I presume that will present other challenges regarding permissions.

End goal: I'm based in the US now but come from a small ethnic group in Ghana (Konkomba) and recently came to the sand realization that our language will die over time. I want to build enough tools for translating to and from English and in the process perhaps learn things about language that fit with the models of the most popular languages today.
Unrelated, going to finally setup a personal website to host pictures and 99% chance it'll be WordPress-based.
Well, one of it's bedrooms was wallpapered and ancient looking. Very ugly. I decided to take care of it.
The wallpaper, and the three papers that came before it, are now stripped. The wall is in rough shape post-strip, and I'm repairing it. This room is on its way to perfection.
I've never done this before, and had no idea how much fun it is. There is no mistake that can't be fixed, and the instruction on YouTube is amazing. I'm having to reel myself in a bit, because I keep on noticing other things I'd like to fix myself. :)
It's sort of like the experience I had when I first started writing software. The power! My creativity is kicking in hard.
So far 8 games, adding more weekly. Games follow the same code patterns, so about a week to add one.
Everything runs on Firebase, needed something to launch quickly with real-time capabilities. Vue on front-end.
Would love some feedback.
Currently on the verge of founding a (possibly viable) startup with it, but the browser itself is totally alpha for now.
Been working on parsers and protocols for a while now, and had to switch to TDD to keep my sanity together. Needed to write my own test runner that can simulate network behaviours (2G slow fragmentation is real) and peer to peer scenarios. Most servers out there don't comply with specifications, so making my own client- or peer-side implementations work was a hard task.
Currently writing my own SGML parser and optimizer, so that the browser receives only "linted and upgraded" html that is free of malicious parts, whilst embracing the idea of disallowing everything that could be potentially misused, including CDNs that do cache busting all the time.
The idea behind the browser concept is that trust is not established by default, and users should decide what website to trust, and match that with what kind of content they'd expect the website to deliver.
The problem nearly every fire department which is based on volunteers have, is that it's hard to learn the location of all items on the different vehicles.
So i build a small quizz app to support the fire departments with this. Now every fireman can learn the location of the items on the go.

I have a raspberry pi and picamera and wanted to detect the pigeons in my balcony and then play a sound or something to shoo them away.
But it's going nowhere, I'm too dumb to even start properly :(
- Nvidia and CUDA stuff is so hard, I can't set it up properly no matter what
- Tried YOLO but without CUDA and OpenCV I can't run it in video. Don't know how to fix it
- Tried to copy other projects but can't find anything that I can parse with my amateur brain. I get lost and doesn't matter how many youtube videos I watch or stackoverflow pages I check, it's errors after errors after errors.
- Tried in windows but that's not viable. Installing Ubuntu nearly broke my pc and somehow a virtualbox messes up the whole thing. Currently looking at this.
So yeah big mess, I'm way over my head and it's not fun anymore. But I still want to shoo away the pigeons and love the idea of learning more about DL/CV but guess I need to learn about the basics first, practice in other things before doing this.
I moved into a house late last fall, so I actually have some space to do so. This scratches multiple itches for me.
Itch the first: I've missed having a vegetable garden since I moved out of my parent's place and into apartment life years ago. While a small garden plot can't wholly replace the need to go to the grocery store for fruits and vegetables due to the inherent seasonality of growing food at small scale, it's damn hard to beat truly fresh fruits and vegetables that were picked not an hour before they landed on your plate. And any surplus left when the growing season is over can be preserved and stored for the winter.
Itch the second: It's _my_ creation, not my father's with which I am merely helping. When living with my parents, my father had his way that he'd like to lay the garden out. Granting that a man who grew up in a rural agricultural community probably knows a thing or about vegetable gardening, watching how he did stuff did always leave me wondering if there wasn't room for improvement. Since this is my garden, I can make my own experiments and decisions on how the garden is to be arranged, and what vegetables I want to grow (e.g dad loves beets; I do not). I've been reading about companion planting, and am eager to try things like growing corn and beans together, or growing chives near my peppers and tomatoes to keep aphids away (seriously, fuck aphids).
Itch the third: It lets me develop useful skills outside of my career in tech. While I have no delusions about quitting being a sys/net admin and going and becoming a farmer, I do think it's important to nurture useful skills outside one's main career.
Itch the fourth: I have something to automate with tech. Gardens do need to be watered. Under-watering will limit your yield, but over-watering is also harmful to both the garden and the wider ecosystem of one's immediate area. There's a goldilocks-zone when it comes to watering, and the just-right amount of water depends on a number of things: what you're growing, your climate, the soil, etc. There is a real danger that before the close of summer, the garden bed will have an automatic, multi-zone drip irrigation system, complete with soil-moisture sensors, controlled by a Raspberry Pi or similar SBC.
During April I built a loft bed frame out of framing lumber. I can post about that too if any of you are interested.
Currently I'm working on an Electron app for automatically importing/managing screenshots and recordings from your Nintendo Switch, off the SD card. It matches the file name IDs (Nintendo uses these seemingly random IDs for each game) with the actual game name, moves it into a custom folder structure, etc.
https://github.com/gedrick/SpotifyKaraoke (live)

My pick: http://seriesreminder.net It was going to be the first choice when you wanted a new series recommended or just wanted to see which tv shows will air this week.
It was still using Rails 5 and Sprockets so I had to make the proper upgrades (including migration to Webpacker) and revamped the design using React and MaterialUI. I wrote an article about that https://medium.com/@cionescu1/how-to-use-react-components-in...
My only goal moving forward is to find the sweet spot (not really MVP, but a nicely working state) where I can go back to just ignoring this project again
I started playing the new Animal Crossing and wanted a good reference for all the fish and bugs to catch. I wasn't happy with static tables that were hard to sort and filter, so I created the interactive reference tool that I wanted: https://ac-catches.com/
First site I've made with TypeScript, so at least I was learning something along the way.
I was continuously fighting my recipe planning. I did it for a long time in Google Keep. I can't manage recipes there, I have to add items to the shopping list manually. Changes in menu planning don't keep up with the shopping list, I forget to check the pantry. Etc. This time looked right to create something to mitigate the frustrations.
The technology is quite simple, it is a CRUD app in Flask with SQL backend. Everything is a docker container with data in a volume. UX is now quite limited, based on Fomantic UI. There is no goal to make it Saas, for friends I will just spin up a second instance.
I have been a software engineer for over a decade, but haven't been programming the last 5 years. Besides I am a fanatic home cook. So this looked like the perfect opportunity to have some fun again.
I started learning Ansible recently using the 'Ansible for Devops' book. I used the concepts mentioned in this book and used the author's Ansible roles as a starting point to create a playbook for deploying Rails 6 apps.
Here's the code - https://github.com/EmailThis/ansible-rails
It includes roles for performing the following tasks -
* Installation of common packages, basic SSH security
* Install NGINX, Certbot (for Letsencrypt SSL Certs)
* Ruby (via rbenv)
* Rails 6, Puma, Sidekiq
* Redis
* Nodejs/Webpack/yarn
* Postgresql + saving backups to S3
* Deploying using Ansistrano
First I'm starting with just a software version because cross-compiling for the pi-zero is kind of annoying.
Intended to be used by our team as we work remotely, but hopefully it'll be open-sourced soon after.
The hoped-for result is that you can run the tool on a directory and it will identify the files correctly and insert the metadata so that it is all consistent and correct. You can then copy the files to your favorite devices, and easily find what you want, make playlists easily, etc.
My current stage is researching the current tools, which are all (so far) partial solutions and IMHO cumbersome to use.
A Chip-8 emulator written in Go, and a small blog post: - https://github.com/bradford-hamilton/chippy - https://medium.com/@bradford_hamilton/building-a-chip-8-emul...

We've been able to host quizzes with over 250 teams, scoring their answers in real time. The scoreboard is auto generated and players can make a contribution with stripe.
So far we've given over 6k euros to various local charities. I'm very proud of what we've achieved so far.
My other project is harmonica karaoke. I'm not a blues player, I'm more into classic rock and country. Since I'm not that good at improvising, I like to take a song and work on it over and over again to work out a nice part and get the nuances just right.
One is Dreams by Fleetwood Mac, where I play the vocal lead with some jazzy stuff mixed in. I live a few blocks from Menlo-Atherton High School, where Stevie Nicks and Lindsey Buckingham met, so it's always fun to play one of her songs. (Harp: Lee Oskar F Major retuned as a high octave C Melody Maker.)
Another is Wagon Wheel, where I worked out the fiddle and organ parts plus some piccolo parts that I made up. (Harp: Lee Oskar A Natural Minor.)
My new lockdown song has been Atomic by Blondie. This one has been super fun! It took a lot of experimenting and trying stuff out, but I came up with an arrangement I'm pretty happy with. Now to beta test at our next Alteryx Got Talent virtual show! (Harp: Lee Oskar E Natural Minor.)
Maybe when we can all do it again, I will get to play some of these songs with other musicians.
A simple example is imagine a game with 10 tickets sold for $1 each and a single $9 grand prize.
If 1 ticket is sold each day and if the lottery publishes the number of remaining winning tickets each day, then you can just wait 1 day and if 1 ticket was sold and 9 tickets remain and the prize wasn't claimed, well now there is a 1/9 chance of winning $9 and the expected value is even.
I started scraping several state for daily numbers and calculating the expected value of each game. Every now and then one gets over 100% EV. (Not taking into account annuity discounts and taxes)
It's also an excuse to try out a lot of different technology and patterns that would be too experimental for most real jobs, so it's a great side project.
I'm currently working on a user section with Clojure, Fulcro (https://fulcro.fulcrologic.com/), and Crux (https://github.com/juxt/crux).
Another fun little side project that was also an excuse to work with Clojure was https://ezmonic.com/. The app was built with ShadowCLJS, Re-Frame, and ReactNative. I've used the Major System mnemonic to remember things like my credit card numbers and I've always wanted to know how optimally short the mnemonics I come up with are. That app uses the CMU phonetic dictionary to search for an optimal phrase.
There's a book by the IMBA (International Mountain Bike Association) that has extensive guides on how to create all sorts of features sustainably.
The stack is Django + Gunicorn / nginx, PostgreSQL and some Intercooler.js and vanilla JS to make the experience smoother.
I've also been trying to learn Elixir + Phoenix, as I find some of the concepts (e.g. LiveView) very promising.
The second project is a custom deck of cards, but instead of the Typical King, Queen and Jack it is royalty from Nigeria and has had an amazing response on Kickstarter

It's all written in Rust. I started to pursue the idea as a "Getting started" project for Rust, because audio needs to be processed in real-time and so a fast language was needed. It turned out quite well and I really like Rust now!
I also wanted Obsidian to be very extensible, and the private beta community has already started extending it and it's so cool: https://github.com/kmaasrud/awesome-obsidian
It's called Who Paid More (https://whopaidmore.com) and the idea is pretty frivolous. Every day (EDT) you volunteer an amount you want to pay to see how your amount stacks up against others for that day. Think ranking and relative % across users for that period and the ability to share those results. Not much more to it at the moment.
I feel a little stuck trying to think of what would make it more fun/novel/rewarding besides just being curious about what people put money into.
I've got a very naive global market running with some incredibly dumb bots, and am currently implementing local markets with their own needs/wants.
It's multiplayer by design so hopefully at some point I'll have some nascent player-base competing with each other =)...
I'm trying to keep everything simple and scope small.
To be honest, I wasn't really expecting anyone to ever be interested in my toy project, beyond spending a half hour idling their time, but a friend of mine has already started kicking the tyres which is very exciting, he's written a bot that scrapes the site and trades against it which I find hilarious.
There's far too much I could write here about ideas, but I'm just trying to keep my mouth shut and make it ;)...
Another separate innovation that I have in mind is combining that with a special run-length encoding sequence that, due to the interaction between LZAP and run-length encoding, actually wouldn't encode runs linearly but exponentially[3]. That is, instead of "repeat substring X for N times" it would say "repeat substring X for fibonnacci(N) times". I suspect that might actually be a novel innovation!
Aside from a lack of time and energy, the main thing holding me back has been, and I'm dead serious, off-by-one errors. It's really, really easy to screw up the order of adding new entries to the dictionary on both the compression/decompression side in such a way that you just get garbage out, and it's a pain to debug.
If my algo turns out to be original, I'm tempted to call it LZWAN, or Lempel Ziv With Amnesiac Nodes (referring to the nodes in the trie used to grow the dictionary).

If you're thinking about doing the same, for formats and media, I settled on:
DVDs: yes, they're old, but they support more resolution than VHS, and practically every new Bluray player still plays them. Also, DVDs support 352x480 resolution. It's still more than VHS, and you can squeeze more content on the disc or encode it at a higher quality.
VP9+Opus+webm on a DVD. This codec/container combo is supported by Firefox, Chrome, Windows Media Player, and Android, so while new, I expected it to be supported for a long time. AV1 looks promising, but probably not ready.
I'm not bothering, but for iOS, use x264 and AAC in an mp4 container. Those were the only modern codecs and containers I got to work. Also, Apple, x264 and x265 are good, and all, but there's no excuse to not support VP9.
I'm saving the unencoded files as ffv1/flac in an mkv container.
For the actual DVDs, I'm using MDisc archival media.
It's a buggy work-in-process app built in Svelte and PouchDB and definitely not in a "Show HN" state yet. I put my progress up on Github pages for close friends to try [1], but what the heck, I'll put it here too (no instructions or videos yet).
I honestly haven't figured out what I'm going to do with it long term, whether to make it free or to try to monetize it somehow. Right now, my main goal is to fold it into an Electron app and have it sync with a Couch/Pouch db server once the main UI code is done.
[1] https://bt-apps.github.io/braintapper_edge
Note it's not a Saas, so no sign up required to try it. PouchDB is storing the data in your browser in IndexedDB so you can delete your data by clearing your browser data for that URL.
So I created such a stack - the Knests stack (https://github.com/tudorconstantin/knests).
I actually started to work on this in December, but I published it a few days ago.
Please beware that in order to use it for your projects right now you'd have to be quite comfortable with the nodejs ecosystem because the whole stack is not quite tidied up.
Digital piano lessons over meet.jit.si aren't as great as in person, but at least I'm able to keep up with it. Currently working on Liebesträume and Handel's Sarabande on the classical side of things and In The Mood on the jazz side.
The XMPP library is going well and I'm hopefully about to start rewriting the authentication bits: https://mellium.im/xmpp/
And finally, I've got some I-Ds submitted and in discussion in the IETF's TLS and KITTEN working groups. One that documents best practices for authentication and password hashing and storage: https://datatracker.ietf.org/doc/draft-whited-kitten-passwor... and one that defines a channel binding mechanism for making tokens and secrets only valid over a specific TLS session (right now it's specific to SCRAM based auth, but that will likely change soon): https://datatracker.ietf.org/doc/draft-whited-tls-channel-bi...

Writing assembly code and see it running on your own emulator feels awesome. Yesterday I started to implement simple text rendering using the GBA bitmap modes.
I also added a WebAssembly port using emscripten (which was easier than expected for a SDL2 based application).
* stealthcheck[0] - Service health monitoring with email alerts and automated restarts in <150 lines of code. Just create a checks.json config file where each check includes a check command, interval, and on-fail command. Set up multiple stealthcheck instances all pointing at each other for redundancy.
* quarantest[1] - Most CI testing tools focus on automated tests, but sometimes the changes are very visual and you just want to give your team a demo of your pull request to play with. quarantest runs a build for each GitHub PR, generates a URL for the build, then posts a comment on the PR with a link to the build. You can see an example of it in action here[2]. Still in a pretty hacky state. Probably would be better to use the GH status API with a link that goes to a page listing all the past builds from the PR instead of spamming comments, but it's getting the job done.

Working from home puts this within arms reach all day long. So while sometimes I get really busy and ignore it, when I become aware of it I start flipping floppies again. Once every few dozen floppies when a label read fails/etc then I type in a new disk series and let it rip.
I did all the music CD's a few years ago, most of my 8x10 photos last year (the fastfoto 640 is awesome, it needs a bigger feeder though).
Next up are the 5.25"s, and a bunch of QIC80 tapes I used like floppies in the mid 1990's. I've also got a stack of harddrives from the past ~30 years I need to capture.
Of course I've got the usual set of small projects as well, but I have to be careful about doing those because I can accidentally lose a day that I should be doing actual work i'm getting paid for. The flipping floppies/etc is a good background no brain activity.
Although my website got a lot of organic traffic and orders within the first two weeks, I was unable to fulfill most orders since manufacturing was on pause and everything was already sold out.
Since then I've continued studying SCM, and I'm also learning Python so that I can build a model to predict this kind of event in the future.
So far so good, it's pretty good to play now, still need more action regulation. The piano had been stored on its side for years, lots of transport, water and insect damage.
Current project: Intermezzo no. 6 by David Benoit: https://open.spotify.com/track/0MJ4ikwkXV4lJiRjklWhS9 (sorry, can't find a youtube link).
Total spent: $100 for the piano, $100 to transport it, $50 to buy string steel to replace the strings that had broken. There is still some worn felt in there as well that will need replacing, mostly on the hammer rest bar and the bottom of the jack support bar. Shaping the hammers was a tricky job (they'd worn down quite a bit, to the point where the original shape was hard to determine).
All in all very satisfying.
Real-time board games over webRTC video chat. I have chess, checkers, and a scrabble clone.
I've passed it around to friends and to some low traffic forums. The rendering library is a bit heavy for a board game (it makes my laptop's fan spin :)) so I'm fixing that before I share it more widely
A side-affect of all this PDF works is that my app now supports all system printers (inkjet/laser) including fancy color label printers from Epson, Primera, Afinia, etc.
Printing labels has always been a total pain, especially on Mac. My goal is to make label printing an enjoyable process for both Windows and Mac users. Check it out at https://label.live

https://github.com/MitMaro/git-interactive-rebase-tool
The tool/utility provides an easy interface for managing the interactive rebase TODO file. It's heavily inspired by vim and I have plans to expand the functionality.
I had tried a similar tool that was written using Node.js but that seemed like overkill. After ranting about the lack of a good tool, my co-worker at the time challenged me to write it that evening after work. I added to the challenge that I would write it Rust since I had not used the language before and I had heard several good things about it. After hacking away for several hours that evening, I had a working prototype to show at work the next day. Since then the project has evolved a lot and it's gained some traction. It now has a small community behind it, which is really awesome!
I have finally, after some 5 years, setup my RaspberryPi to perform a useful function for me. To validate the claims by my ISP makes about our bandwidth. It's performing a speedtest periodically and updating a Google Sheet with the results. Over time I hope to track and back up their guarantee myself! In the process I am learning about Go, Docker and Google's API. I am also increasing my knowledge of Linux. The project continues with more automation and monitoring.
I've recorded on 2 separate occasions bass lines for different bands in a simple home studio which has been put together since lockdown. I'm collaborating more with a teenage friend whom I used to record and perform with a lot many years ago.
Also, briefly: I've built my family home in Minecraft and plan on extending to some memorable landmarks...
And I hope to get round to reversing the fridge doors before the end!
873 rules, so far. And 99% done. Arguably Vim’s largest syntax file to-date.
Best part? It highlights RED if you type the configuration wrong. As well as TODO, FIXME and nested 3-style comments

I launched it a month ago. It's a tool that converts your un-used domains into something useful.
By something useful, I mean a self-running automated content aggregator with lots of bells and whistles to keep it running (e.g. membership, newsletters, ads).
I had way too many domain names that are not being used. I wanted to make some use of them without having to maintain them and spending time on it. Now I have all of my 25 un-used domains.

Tonight I had a super exciting evening, as I set up a local server for MSN messenger.

The 9 year old can type quite well already, and figured out how to change her font, while the 6 year old keeps sending me nudges, dancing pigs, and audio clips yelling "MIIIIIICROPHONE". It’s great to have a local server with no minimum age limit (unlike Facebook, GMail, etc) and no risk of creepy friend requests.

Actually, I didn't become a movie buff with tools like this but with watching the movies liked by the directors of my favorite films. For instance: Pulp Fiction -> Quentin Tarantino -> Bande à part -> Jean-Luc Godard -> Robert Bresson -> ...
In addition to giving you some ideas about films that you could like, this helps you to better see the big picture (no pun intended). You learn about the important movie periods and movements (French New Wave, Italian neorealism, New Hollywood...), you develop a more serious approach to film, and you can live these mind-blowing moments when you notice similarities between two movies done 50 years apart and that looked at first glance totally different.
I already created the engine (which is giving good results for my profile! It recommends me movies that I never thought of). The challenge was mostly to found all the data required by the engine. Now, I must admit I'm procrastinating a little bit for developing the actual web app!
(and thank you everyone for your messages, your projects are awesome!)
The concept is simple: If twitter + youtube had a baby for learning.
An interesting side effect: I've personally had a hard time getting started with writing, and ever since I've launched smalltuts, I've created a new course almost every day.

I was doing weekly groceries since last summer and had partially automated the process of aggregating the ingredients into one grocery list already.
When the social distancing started I figured maybe others would find this tool useful, so I spent a couple of days building a usable interface and account creation features and told some friends on Facebook. Nobody, besides me and my girlfriend, ended up really using it, but it was a nice exercise nonetheless ;).
I've also been on-and-off learning Zig, both in support of the above (Zig on the N64 seems to be uncharted territory that I'd love to help explore) and in support of development of a Tcl-like programming/scripting/config language (iterating on my learnings from an earlier project of mine² implementing such a language on top of Erlang/OTP); the latter's something that's been bouncing around in my head for a few years now, and I feel like I'm at the point where I'm ready to start bouncing those ideas into an Emacs buffer, lol (especially now that I've found what seems to be the right host language in which to implement it).
EDIT: oh, and early into quarantine I did submit my first ever patch to wine-staging³ (with quite a bit of help from a couple others, including one of the wine-staging maintainers) to fix a mouse cursor/movement bug in Mount & Blade II: Bannerlord under Wine/Proton. It's a small patch, but it's my patch nonetheless, and it's a surreal and proud feeling to see my name in the commits for software I use almost daily. It's also helped demystify Wine a bit for me, and I look forward to continuing to do my part to make it better.

I created https://fruitionsite.com, a free, open source toolkit for building websites with Notion. You get pretty URL slugs, custom domain, and a whole bunch of other features.
I hacked it together in a weekend, put up the marketing site (using Fruition, oh so meta) and shared it in Notion's Facebook group and subreddit, without any expectations that it would go anywhere.
The response has been incredible. 11000 people have checked it out since. It ended up on the Product Hunt newsletter [1]. People are making YouTube videos [2] about it. Chris Coyier of CSS-Tricks [3] shared it too.
The biggest lesson for me was just launch it. There were many more things I wanted to add. But I decided to share it publicly before it was perfect. Now I have users who can give me real feedback rather than me pretending I know what people want.

Compared to EF, you author your projections in a sandbox where you can get familiar with your data as you build up your projection. Compared to stored procs, your queries are versioned and distributed with the app. Compared to Dapper and ADO, your SQL lives in a real environment and you have zero mappings to maintain. This ought to change the world, no?
Being able to access all my things, consistently in the same app, across devices, machines and networks is super-neat, and Riot[2] is a really smooth Matrix-client, on mobile, web and desktop.
This is without a doubt the most productive spare-time hacking I've done in a good while!
I'm curious how devs with kids at home manage the current situation. The constant multitasking stresses me a lot, I feel incapable of doing anything tech-related that would involve deep focus.
Does cleaning up the flat count as side project :D?
I've been an indie-hacker for 10 years so have seen the effects of my programming decisions over the same period. I've seen how fads come and go, sometimes wreaking havoc. I've also seen how coding decisions affect business (such as strategies to transform data into seo at scales of 10k+ items). I've seen how to keep something running day-and-night as if your livelihood depended on it - since it very much does.
That's the game plan anyway. I'm five episodes in: https://m.youtube.com/channel/UC17mJJnvzAa_e9qQqLIfIeQ
For fun I took up the tenor ukulele. Compared to any other instrument I've tried, it's got a much kinder learning curve. You can sound alright playing four-chord rock and pop songs in easier keys like C major after a month.

I published an article about Zettelkästen: https://github.com/alefore/weblog/blob/master/zettelkasten.m...
I'm also working on an article about software correctness, summarizing my experience working on infrastructure software at Google for about 13 years. It's very incomplete and I'll probably end up restructuring it significantly (not very happy with the current logical structure). I only started working on this two or three weeks ago (as a side project), so I'm satisfied with the progress I've been able to make: https://github.com/alefore/weblog/blob/master/software-corre...
I'm also working on other similar articles on other topics (Bitcoin, Stoicism, Bauhaus), but those are even less complete.
Lastly, I've continued to make significant improvements to my text editor (https://github.com/alefore/edge).
I think it's interesting that I'm finding it hard to focus on some topics, but I'm currently very productive in others.
I tend to end up doing general geek stuff for small manufacturing businesses. At a certain point they always ask about scheduling automation because their one person who runs the shop can't keep track of everything any more. The existing scheduling solutions are either too far down the rabbit hole of job-shop-scheduling yak shaving to fit or attached to an ERP that's out of their price range for a while.
In this case scheduling automation doesn't have to be perfect. It shouldn't be, it's a waste of time. These users haven't grown into habits that fit an optimized solution; their manufacturing data has been treated as an arcane nuisance because it hasn't provided benefits yet. All they need is something basic to get them started on the way to better habits and improving their data while improving scheduling. I don't know how far I'll get, but it's cathartic and educational to work on for now.
I've seen women posting on solo travelling facebook groups their current or next location and PM each other, especially in non-english language groups.
With the app, you would receive a notification when a new traveller (speaking your native tongue or not) is close using geolocation, then you check their facebook profile and message them (via messenger).
No need to display the app: you just wait for the notifications (which frequency can be changed). This is my idea for solving the egg & chicken problem, so obviously the app doesn't display ads (and is free).
Definitely one of my favorite hobbies: over-engineering.
All contributions are welcome, however we're working 2 fulltime jobs and care for a 3 yo in lockdown, so time to work on this project is a luxury.
It's on github: https://github.com/t-tran/slack-chat-backup
Sounds dumb but could be nice one day in the future to be able to look back at it. Also wrote it in Rust so I'm learning a new language while I'm at it.

A plus side these days is that it takes enormous amounts of time. For people interested in starting out: My 2019 13" MBP is fast enough for it to be fun, at least for now. So you don't need to worry too much about GPU performance.

Up to 2,000 subscribers now which is very motivating! I feel like there is a lot of demand for this information, but there is a shortage of people who are sharing how to implement trading systems with Python. So I'm teaching myself and sharing on YouTube as I learn.
Hypothesis: As many of us work from home, there are several different things we all do. Be it cooking, hobbies, writing etc. WFH Cave is a place to share your projects and help inspire each other. I currently have around 30 users, mostly friends and family.
Feedback that would help - what is that would stick here. Currently it feels like a normal photo sharing site. Any ideas would be much appreciated.
There were a lot of layoffs recently, so I wanted to do whatever I can to help my fellow engineers. I unfortunately can't help with referrals, but what I can do is share my experience and knowledge. I love Dynamic Programming and decided to record a YouTube course [1] explaining the topic as simple as possible (ELI5).
A lot of people struggle with DP and if you are one of those, feel free to subscribe. I release new videos every Sunday.
Also, since I'm not an an experienced YouTuber and English is my second language, feedback is a massive motivator for me. So, if you have any feedback to share, please, let me know what needs to be improved and I'll make sure to work on it.

An art project to remind people that the COVID-19 deaths are not just a statistic to track the numbers. Each death is a tragedy.
Real and simulated obituaries are presented at the current death rate by country, age, and gender.
Take a moment to reflect on each one.
Using D and OpenGL. Might rewrite it to WebGPU in the future when it gets more stable.
Operating under the codename Portobello for now but friends and family don't like the name. The landing page is atrocious, but the actual app functionality is nearing an MVP.
I guess the big question for me is do I make it realtime for the launch. The handshake for swapping keys and allowing access to a board/organisation currently happens via HTTP polling, but that's not such a nice experience. Currently the whole thing is hosted on Netlify so moving to websockets would require me to set up another service somewhere, not sure if it's worth it before I validate my idea.
I'm going to do an official launch on Hacker News within the next couple of weeks. Still a lot to do as you'll see.
Instead of renting a GPU instance and setting up a Flask web server, you use git to push your trained model to Flux with some configuration and get back an http endpoint.
For example, you set that your input is the url to an image, and that your output should be the top classification and its likelihood, and that your model is in pytorch.
For example if you have a classifier for dog breeds you:
Make a POST to fluxdeploy.com/username/dog-classifier with json { “url”: “...” } And get back { “klass”: “Great Dane”, “probability”: 0.937373 }
No need to do your own devops, Flux will scale for you. And it’s priced per-request and cheaper than hosting your own web server. Flux also deals with versioning and dependencies.
Still working on streaming inputs like video.
The app itself is a bit of a different take on the problem space than many of the other well-known offerings in the market. iOS only for now, SwiftUI, and built around enabling "Compelling & Comprehensible Input"-based language acquisition using video, audio, and text you've supplied yourself.
Interestingly - when I started the project I reckoned it would be about 2 years to shipping something useful, which would mean about Q3/Q4 2020. I'm starting to think that estimate was, shockingly, about right.
Cheers to everyone and their projects!
More seriously, I'm trying to get in the habit of not talking about any side project I've not shipped yet, since when I "announce" them in advance I end up not shipping anything. Turns out this might actually have a basis in science, as recent studies allege that the brain "discharges" some energy/motivation when one talks about future plans.
By far the hardest thing for me to grasp has been CSS, it’s just so weird and feels so un natural at some points. There are so many ways to do the same thing, which feels a little overwhelming. Also in awe of grid layouts, which I just learned about so at least that’s a good thing!

I'm looking for beta users if you dig the idea and want to help out a feel HNer.

After almost finishing it (only few bugs left) I decided to not bother trying to release it. Like most projects my initial enthusiasm went out the window once I got something working. It’s so ripe for abuse too that it would probably make people feel worse about themselves rather than better. I always sort of knew this but the enthusiasm for the better of me.
I’m instead going to open source all the parts of it (the web app, the sql to recreate the dB, the mobile app, and the API) as that probably has more impact.
For now it still up at https://ottr.chat
My 11 year old son has decided we wants to make a table for his younger brother, so that might turn into a side project for me. If I'm lucky it turns into a side project for our carpenter neighbour instead.

Rallying others to unplug an entire new development that is leeching from our community transformer / meter. And then trying to build bridges so they start chiming in with $ if they want to connect again.
Now that everyone is at their households all the time it is easier to have people pay attention to chronic problems and fix them for good.
The other project is getting old computers of mine fixed up and giving them to households around with more than one child. Here in Colombia a lot of schools started doing remote but only 50% of kids have equipment to connect from.
It already works well, but there's still a lot to do, like showing aircraft routes on a map. The overall data provides a nice trend that is statistically stable, but since free aircraft data is hard to come by, coverage of regions that are not Europe or North America is not that great unfortunately.

I wanted a free, easy way to listen to music with my friends, so I built this a month ago. It's still pretty rough around the edges, but it's simple and usable enough. It's mostly Go, with a nice ring buffer to keep streaming synchronised.
Also, baking a lot of banana bread.
It's currently in MVP and I'd like to add more "fun" features to it to push it further into the social space and keep it out of the enterprise territory that MS Teams and Zoom occupy.

My goal is to help people to read any Japanese website by adding information about the vocabuary words (pronunciation, meaning).
But at the same time I want this to be highly customizable and easy to use, because helping too much or systematically does not actually help to learn. So this has to be just right for everyone to be truly useful.
It is not released yet, but I made a mini-website and have a Twitter account for this project if anyone is interested:

My vision for the project is to give learners the basic foundation of vocabulary, kanji, and grammar and to expose them as early as possible to native content (something that I wish I did sooner). For that reason, I utilize various media such as tweets and YouTube videos to make the content more natural (i.e. not textbookish), relevant, and engaging.
The project is still far from completion. A few days ago, I shared the early version of kanji module (https://xn--wgv71a119e.app/漢字) to a reddit community. If you are interested in the details, please check the post below:

Technology-wise, I am building the website with Next.js and wrote all sort of scripts such as asset generation, dictionary, and parser in Go. Aside from no support for utf-8 route in Next.js (I had to hack few things to make it work), the development has been smooth and pleasant.

There're a lot of apps that are either focused on one weightlifting routine (like 5x5 StrongLifts or Five3One) - they do nice job leading you through the routine, but if you want to try another one, you basically need another app. And if you want to create a custom routine, you're out of luck. There're also generic ones, like Strong or Jefit, but it's hard to make them follow some specific routine, increasing and decreasing weights automatically, changing exercises when necessary, etc.
I thought - how hard would it be to create a platform, that'd support many routines, and you'd choose any, and have a consistent UI across them you got used to?
Another thing I wanted to see - how hard it is to create a PWA app that is nice to use, and what features are still lacking there (compared to native experience).
The app is already in a usable shape, I use it 3 times a week, though it only has one working routine now. It's written in Preact/Redux/TypeScript.
It's a surprisingly pleasant experience to have a personal project like that, and slowly build it in your own pace, working on features you care, that would actually help you in your workouts. I found myself sometimes working on it til late night, being in that "flow", like in the beginning of my career, having so much fun, and returning back the joy of coding!
For example, you can have everyone in the meeting speak one after the other (the app handles muting and un-muting the right people), then repeatedly shuffle people into pairs so that everyone gets to talk 1-on-1 with everyone else. Or have a “speed-dating” style format for the first 20 minutes of your remote meetup, before bringing everyone back to the main room for the main speakers.
Barely ready to open it up yet, using it to host daily "standups" with my friends, but going to have a few friend gatherings with it later, and maybe a local meetup. The friend gathering will have the first schedule I mentioned above; have everyone speak in a circle to catch up the group on what they've been doing, then split the group into pairs (shuffling the pairs). The meetup will have the "speed-dating" + switch to main talks.
Uses Jitsi for the hard video webRTC stuff, and then nextjs with socketio for my application.

Getting back into React and ES6, and all the amazing new CSS stuff of the last 5 years!
Eventually I want to split it off so that the logic can be in its own package, to make it easy to integrate different speaking formats into different, existing apps.
(Built with three.js / react-three-fiber, and a simple Node backend.)
I'd love any feedback!
I had used apps like Donut before and they felt oddly pushy and impersonal; you join a room and Donut will randomly select people to chat. Have you ever been in one of those arrangements? Extremely awkward openers. I wanted the questions to serve as a fun icebreaker to help people naturally discover interests together.
Oh and of course the tech. It's all built on Elixir. I run one web server and one database server and that's it. I already have about 100 communities spanning about 4000 people so in terms of message/event processing it is completely seamless...one of my favorite things about Elixir. Most interactions are processed in measure of microseconds rather than milliseconds. This makes for a real-time experience in Slack and is such a joy to work with. I also contribute to the Elixir-Slack open source project which has been fun working with as well.
I hope to incorporate more user feedback as it grows but so far it's been a great tool for teams in lockdown as they ramp up new people and want to quickly build them into their teams' culture.
Almost finished the MVP, one more 3 days weekend and that should be it.
Next.js + Mongodb + Auth0 + Stripe + TailwindCSS
I apologise if folks have already seen it, since it actually (surprisingly) got a bunch of traction here on HN over the weekend, but that has been our quarantine project, for what it's worth!
End goal is to clean a portion of bath tub or toiler semi-autonomously: manually attach different tooling like cleaning agent spray and brushes, but let the robot do the rest of work.

Simple service to get the public IP address based on IPIFY API.
Lots of services already exist like this and my favorite is icanhazip.com. This is basically the same old service in a more memorable domain name. But it is helping me trying to learn Go and API development. https://about.ipaddress.sh/
It's a web app to make podcasts out of Youtube channels. Launched a couple of weeks back.
Snowdrift.coop is a crowdfunding platform specifically for free/libre/open (FLO) public goods -- freely-licensed software, music, journalism, research, etc. It's based on a new funding mechanism we call Crowdmatching, where patrons pledge to support projects with a monthly donation proportional to the number of others making the same pledge ($1 per 1000 patrons).
We operate as a non-profit cooperative. The site itself is free software, written in Haskell (yesod) and we've also tried to stick with FLO tooling whenever possible, although we made an exception for hosting our source code, which is at https://gitlab.com/snowdrift/snowdrift
Of course, as a free software project, we suffer from the same funding issues we're trying to solve. The project is currently a 100% volunteer effort, and we're making slow (but nonzero!) progress towards our initial launch, when we start hosting our first outside projects.
One of our biggest bottlenecks right now is developer bandwidth. We have a handful of updated designs that address UX issues with the live site, and need to get them implemented -- if you know css, haskell, or both, we'd appreciate help!
In addition to replying here, you can also reach out on our discourse forum (https://community.snowdrift.coop), irc/matrix (#snowdrift on freenode, bridged with #snowdrift:matrix.org), or gitlab (above).

An alternative to Shopify for
1) People who don't need all the features of Shopify and are more budget conscious
2) People from developing economies with a unique set of needs not addressed by the bigger platforms (e.g. African countries where access to credit cards is lower and where addresses are different/non-standardized)
I read five pages from a book that interests me every day and then write about my interpretation.
To build a good reading and writing habit, I built a static blog using JAMStack technologies.
I used Hugo to make a static site and Netlify functions to call Google Book API, Forestry dot io to write my book blurbs every day. I integrated Amazon ads to implement related book recommendations. I use netlify to host and Github actions for CI/CD. It's a PWA out of the box and supports Google AMP.
The cool part is when writing a book experience, I provide the book ISBN, and my netlify function would go and grab book cover gif, description, author name from Google Book API automatically :-)
I am really pleased. I will start reading and writing from the coming Monday.
Wish me luck and follow me to encourage. I will open-source my Hugo theme which I named ”Morning Pages” and my blog on Github later this week. Cheers
I became overwhelmed with the massive list of content I saved in Pocket/ Instapaper but that I knew I'd never read, so I built myself a similar app where saved content disappears after 7 days.
If I don't read something in the week after I save it, there's a good chance I'm not going to read it ever.
Works well for me so far.
I created a tool that lets you create ebooks from RSS feeds and send them to your Kindle.
I follow several long-form blogs, and I really prefer to read them on the kindle, so this was my attempt to solve this problem.
If anyone else has the same problem, I'd like to get feedback and feature requests!

- A project templating system based on a single Markdown file: (https://github.com/rberenguel/motllo)
- Generating a graph visualisation of my notes in the app Bear, with Graphviz (https://github.com/rberenguel/bear-note-graph)
- A task-executiont tool, a bit like make (https://github.com/rberenguel/paque)
I have also brushed up on D3.js (for a project which hasn't appeared yet, but the result will also be used for the notes graph as an alternative to Graphviz) and generative coding (using p5js and threejs, the latter for fragment shader fractal stuff, https://github.com/rberenguel/sketches, most are still not up there, but only around my twitter feed). The generative coding path is also taking me towards tone.js and ORCΛ, but so far I have only dabbled in them.
I have also tried to spend a bit less time close to the computer per se (the generative "exploration" is done on my iPad mini in the sofa while watching something, for a start), and I have also tried to play some more music (ukulele, harmonica)
Edit: I always forget comments here are not written in Markdown

Because I wanted to know what was going on in the world without too much COVID noise. It is a daily email from Wikipedia’s Current Events portal. Someone mentioned that i could have just used RSS, but it was quite fun to build something so small and have a fully completed project in a day
Three of us are building online board games. Idea is to enable people to bring their board games online, and play with their friends. You can bring boardgames online by simply taking pictures of the board, cards, pieces etc., configure and launch.
Gameplay would be very similar to real world. You have to move the pieces and run the games yourselves unlike the usual online games where 'computer' will do the heavy lifting. We believe that managing the game is big part of having fun. Games will have integrated video chat and can play with friends like real life.
This is still an early stage. For example, we haven't opened up to users adding their own games yet. We added some games to test our platform. We are working on adding more capabilities to enable more games.
Some questions we are looking to find answers for: - would you be willing to play boardgames with the current experience? - what game would you be excited to play here?
I've now integrated it with a couple of systems which allow me to get OHLC data as well as Regulatory News Service articles. And, in order to improve the quality of the forecasts, I'll soon begin integrating it with other news sources.
I've added it to (Collective 2)[https://collective2.com/details/128426551] and its currently making a loss as a strategy. This is good news because it's allowed me to identify why that loss might be occurring and where I could improve my strategy (I've found quite a few improvements in the last few weeks). The most recent improvements are active on a non-visible strategy on collective2
This forecaster could be applied to any global exchange. And I'm looking forward to the day where I can trade with it myself, sell the signals as a service, or sell it for a tidy sum.

Our events are open to the entire East Coast and last week we had 26 players from the US northeast. It is a good time to learn this stuff because it also helps my local community and others get in touch and start finding new players to play for now--and hopefully hang out with/play in person once COVID is lifted.

I’m also trying to build something to keep track of enterprise product requirements, since this is the eternal bane of my day job.
https://github.com/darcys22/godbledger For the most part that backend of the system is working how I want. I now need to build more front end ways to communicate to it. One of the front end methods I’m working on is programmable journal entries. So you write your journal entries in a JavaScript file which gets executed in the context of the accounting system so you will have full access to the account balances. However this is still early stages: Yurnell: https://github.com/darcys22/yurnell
The idea is simple - sign up if you need assistance or volunteer to help out colleagues with resume review, mock interviews, or referral.
If you’ve lost your job recently, tell us what you need help with most. We’ll match you with an amazing volunteer who can provide you with the assistance needed to find your next professional position. * This week, we launched Endorse on a couple of Facebook groups, Slack channels, and LinkedIn and have received ~80 sign-ups so far. We're two engineers who've greatly benefited from the Tech community and have built this as a way to give back. While the # of sign-ups helps validate the idea, we desperately need more volunteers who can help with resume review, mock interviews, and mentorship.

There's all kinds of fun stuff you can learn, like apparently Instagram just ratcheted up the number of ads shown and people don't like it. You can see different text topics people mention, and select time ranges in the volume and rating over time charts to filter.
You can look at other iOS apps too, just by adding the app ID in the search params. This page shows DoorDash's reviews:

It's still very much beta-level in terms of all the things I want in there, but it's been a fun distraction so far!
The premise of the system was simple, you view a pic, type in the registration / license plate then move to the next. It has only three options, add, none visible or same as previous.
The system is offline at min whilst I prepare more images but here is a screen grab:
https://i.imgur.com/qWSiUEV.png
I advertised the link on a forum which I post on and was amazed at the response. The first 10k images I'd prepared were indexed within 24hrs and then a second batch of 20k in the same timeframe. The quality of results was very good, less than 5% error rate.
Ultimately I am going to choose the best and add them to a web site.
Some guys have said they'd like a similar system for their own photos. I suspect there could be a solution there for things like railway / transport photograph community.
Bridge is Chat for Business. It's basically a shopping protocol for chat that works over Telegram, WhatsApp or email – essentially chat commerce. It's not quite ready for a Show HN yet, but so far the interest in my city has been good.
I noticed that more and more companies were doing business over chat. Customers are clamouring to give them money over WhatsApp, Instagram, Telegram and Messenger, but these chat platforms are not designed for trade. Bridge is.
Under lockdown here in South Africa, every business has to become an online business, but traditional eCommerce is too heavy and inflexible for informal traders, especially if there is any barter and negotiation involved over delivery, shipping and payment method. Bridge crosses the chasm by adding structured negotiation to chat.
I've been setting up old GPUs for folding@home and recently acquired a Nvidia Jetson AGX Xavier for machine vision.
Currently I'm building a 6 camera rig using Raspberry Pi IMX219 or IMX477 cameras to create an ultra high FPS rolling shutter.
After getting into this, I've found out that there are a literal crap ton of people selling fakes and it is extremely hard to prove the source of the masks so I've been doing everything possible to provide transparency in the supply chain (including having customer names added directly to production contracts with the manufacturer).
PSA: KN95, N95, FPP2, and other NIOSH certified masks coming out of China are at a minimum around $1.5 per mask FOB (meaning to the manufacturer) then you have to get the masks into America with import taxes, ocean or air freight and then local last mile delivery and warehousing. That easily can add $1 per mask. My point, if anyone is selling masks for <$2 per mask in small quantities, they are probably fake. The raw material cost alone has skyrocketed for 99% material that is used in the production of >95% masks.
For example, our cost to reliably (~20 days) get 2M masks landed in the USA, ends up being $2/mask. That's without any profit and not including local delivery.
Happy to answer any questions! Orders@maskhq.org
Want to try selling licenses as well, let’s see if I can do open source full time.
It is a language based on explicit parallel and sequential composition of expressions (very similar to the concatenative languages family) with an underlying categorical semantic/type theory based on Adjoint Logic (work by Pfenning, Reed,Pruiksma et al and work by Licata, Shulman, et al with the Simple Intutionisitic fragment replaced by a Dependently typed fragment (ala Krishnaswami) and all based on work in the ‘90s by Nick Benton).
I set myself a goal since I’m in lockdown of having a landing page with minimal compiler and hopefully a small web based playgraound published before July 1. I have really been enjoying the work I’m doing on this and hope everyone else is having a good time working on their stuff amidst all the external upheaval.
I've also been enjoying lunchtime and evening walks. Something about going on walks seems to generate many project ideas for me. As a result, my list of projects to work on has been growing way faster than my ability to actually complete those projects.
I noticed that while working on past side projects I spent a lot of time writing simple CRUD APIs, permission checks, client code to connect and model classes which (at least for me) is usually not the most fun part when working on new app idea ;) So I started creating a concept to automate most of that for future projects and developed a simple web platform around it.
During the quarantine I've been mostly working on a set of permission rules to control access to API resources. I also started on generating client code which at least works for Angular at this point. I'm very hopeful that I can stay productive and get it to work for React/VueJS and iOS/Android as well soon :)

Would love to hear any feedback!
I'm in my 30's and have always struggled with how flexible I am. Since lockdown I've spent just about every evening mobilizing anything that feels tight or uncomfortable has been a game changer.
I'm finding that I feel physically pretty great, less tight, aches/pains have faded away though there are still a few old injuries I'm working through.
Lockdown has been hugely helpful in maintaining the habit: kids go down in the evening, take the dog for a walk and stretch until you go to sleep has been a great way to unwind.
If you're looking to get started, I initially followed this guy's[0] youtube channel for a month, then started doing what felt right for me.

It is made for solo maker, indie hackers or solopreneurs who want to quickly design social media content, in bulk.
I think I'm inching towards a stable rhythm though, but time will tell. I always need 2 months of a stable rhythm to be fully sure that I got a rhythm locked in.
Here is what I figured out so far:
- Magnesium before sleeping
- Vitamin D when I wake up, especially now since I'm sitting inside all the time.
- Obviously basic sleep hygiene that all the popular blog posts write about (fun fact: I use Iris instead of Flux, it dims the screen even more).
- Melatonin when I can already tell I won't be able to sleep anytime soon. I used to try to fall asleep on my own strength for way too long. Things I've tried: meditation (my username is derived from it), progressive muscle relaxation, not thinking about anything (I am quite good at this), visualizations of being in familiar places, exercise and going to the doctor. It all doesn't work. What does work: melatonin. Only since recently I've been a bit more aggressive with it (after 25+ years of sleep issues).
This leaves me with one issue: sometimes I wake up after 4 hours of sleep. My usual way of dealing with this is being awake for another 4 hours, so I can sleep my second quartet of hours. The problem: I wake up around 11:00 AM when I go to bed around 11:00 PM.
So what I'm trying now, since my lifestyle supports it, is waking up between 04:00 AM and 06:00 AM so that I have enough leeway to sleep a bit more. I'm starting a job soon and I have to be 09:00 AM in the office. This is my makeshift solution.
I hope it works.
Problem = parents get many suggestions some helpful, some clickbaity or low quality (too much mess/effort/clicking). Solution = crowdsource, moderate, and upvote for the highest quality ideas, categorize them and allow users to bookmark their favorites.
Anyone can submit an idea - a link plus short description and category choice. The moderator (just me right now) checks submissions for safety and quality before publishing them.
Visitors can upvote the ideas they like and submit comments on resources that might help other parents.
Logged in users (just email and password sign up) can bookmark their favorites.

As a heavy VPN consumer, this is really helpful to me :)
I was working on repairing an inflatable dinghy earlier (over a dozen individuals patches!) and finally got it working and moving with a electric trolling motor. I can go free-diving from it and was looking for something else to do. The goal is to be able to put everything in the water-tight enclosure on shore, motor out to a spot in a kelp forest, drop anchor, hop over the side, and swim down to a good spot to place the camera.
When that's done, I'll hang out for a bit playing around in the water or eat lunch/read a book or something in the dinghy, then go back down to grab it and then head back inshore and hope I've gotten some cool imagery!
If anyone's got some tips on how to optimize it, I'm all ears!

I did a show hackernews a month ago and it did pretty well. It's been pretty great since then. I have had people write to me thank you emails and some pretty cool stories like one grandparent that told me they used it to read to their newly born grandchild!
On top of that it has got me back into programming which I don't do in my day job and it finally gave me a project where I can use Phoenix liveview.
Now as a family we have also got into baking bread - we didn't realize how easy it is to make good bread at home and it just taste so much better. It's been a lot of fun and the kids love doing it with us.
A collaborative space to share/vote ideas and questions, in real-time. This was built using Elixir and Phoenix LiveView.

- I re-did a project I first pursued when I was really really young. It's called Mapnews.io and it shows you what's happening where today. It's a collection of RSS News with geolocations shown on a map. Uses Cloudflare Workers & Apple Maps - both have been awesome! Happy for any feedback! https://mapnews.io

Seems like so many of us (myself included) just miss the process of learning, whether that's learning a new skill or just personal development/mindset related concepts.
To help find a course to do, I made this simple one page site and included the most highly rated free courses from across a few different sites, whether that's Coursera, YC, edX or Youtube: https://resumeworded.com/free-online-courses/
So I had the thought of making a chatbot that is hooked up to their inventory database that can tell you where particular items are located. I'm just building the first prototype entirely in AWS, both to learn AWS and to make it easier on myself.
I figure that shoppers will use it because talking to a chatbot feels safer than asking someone in real life, and businesses will want it because it gets people out the door faster so the lines to get in are shorter.
Quarantine (https://quarantine.softwarerero.com/) models a worst case scenario for reaching herd immunity without finding a cure.
Duobiblo (https://app.duobiblo.com/) allows to practice a language showing chapters of the bible side-by-side with a language you already know. I learn Portuguese currently on Duolingo, which inspired the name. If a browser supports the Web Speech API for the given language it is also possible to let the browser read the text.
https://coronavirus.simrnd.com/about/ is a draft of the intentions of the project, and the source code is at https://github.com/jinpan/covid-simulations.

In the repository there are several experiments, each consists of Jupyter/Colab notebook (to see how a model was trained) and demo page (to see a model in action right in the browser).
For now I've created only 10 experiments (i.e. Digits Recognition, Object Detection, Image Classification, "Write like a Shakespeare", etc.). But the plan is to do some more experimentations with GANs and RNNs.
Hopefully I can get it rolled out in time to help other folks with their quarantine side projects!
I know Anki and other alternatives exist, but after having written my own private wiki (10 years ago!), I have found value in DIY'ing important tools.
Yet Another Focus Music generator to solve many of my problems using other services throughout the years.
What works best for me to focus is a combination of many services that exists on the market, so at the end I had to tune into many web apps on my browser which hogged my memory and I had to pay for many subscriptions making it a really expensive solution.
So I created this service, is still a work in progress, but I have been running to polish everything during this quarantine, right now I feel it is at a 90%.
I've been performing intermittent upgrades over the years as I wanted to retain the simplicity, ease of use with a focus on providing the most accurate and clearest Ayat text in any app.
The latest update has incorporated word by word audio timings and advanced play back controls for a completely hands-free operation, even serves as a teleprompter for the Qur'an.
During lockdown, many teachers and companies are looking for new ways to work online, and google searches for "opensource online whiteboard" have exploded. I noticed a surge of activity on the site, and that motivated me to spend more time on it. The tool has also received its most significant external contributions since its inception several years ago. I just hope the interest will not fade away once the pandemic is over.
https://github.com/adrienball/2048-rs https://en.wikipedia.org/wiki/2048_(video_game)

Professors have to run research groups in addition to teaching and committee work. It's very similar but different from the industry/corporate world so I'm working to tailor things specifically to academia.
I had actually started it before the pandemic, but it's even more relevant now! Trying to get a beta out soon very soon, and some real screenshots for the website. It's about 80% there but things are finally moving again for me.
I’ve been working on this for the last month and finally got it working. It will be listed on my site soon.
Work and work out :)

I am working on this full-time, daily. The README is a bit out of date.
Edit: wanted to add a few more details on what my goals are with this project!
1. Being able to easily add audio commentary to hosted video, MST3K and Rifftrax being an example.
2. Being able to do popup video style context and commentary.
3. Drinking games.
4. Instant replays.
5. Picture-in-picture commentary (reaction videos).
5. Pointing out easter eggs or continuity errors in videos (think the hidden ghosts in "The Haunting of Hill House")
Lots of people right now seem to be looking for new ways to get paid / make money / start little businesses from home, and being able to send quick payment links over social / SMS seems a common requirement. (a 2nd / 3rd-order COVID effect I guess!)

Sadly I've got busy with client work again. It needs serious thought about the UI and I need to figure out how to either widen it's appeal or reach its niche audience.
I find it endlessly fascinating and I naturally assumed others would too. :-)
It's largely based on work that John Conway did and I was looking forward to showing it to him at some point. Sadly we both ran out of time.
I've been building a packing list app for ultralight bikepacking, hiking and just a general outdoor gear library. I've had a surge of interest from niche reddit communities and a few hundred test flight users. I'm finding it hard to find time to work on it right now as freelance work is picking up again. Stack wise the majority of the app is written in Kotlin and shared on iOS and Android (haven't got the Android version out yet).
(1) Bython, a basic Python interpreter written in C. I just want to have a taste of what it's like programming out a language so I won't go too far. It is dynamically typed and has automatic memory management. https://github.com/remykarem/bython. PRs welcome!
(2) minishell. This is a simple shell with only 2 commands: either you (i) hit enter to view 10 files of a folder at a time, or you (ii) enter a filename and view nbytes. I built this because a co-worker wanted to view a folder with 20+GB of files but couldn't do it with an `ls`. With this, I hope that we can casually explore a folder without having to print everything. https://github.com/remykarem/minishell.

Of course the AWS console is enormous, and this is just a side project with some resources - not interested in replace the original one, just being able to monitor resources from all the regions we deploy in :-) WIP of course, and I am not a frontend developer, so be gentle :-D
Also writing "teach yourself" lessons for the library ... which is not so much fun, but does helps uncover "softer" bugs like: "why do I expect people to code that thing this way? Is there a simpler, happier way to do it?"
(Yeah. Talking to myself out loud. Not a good habit to develop during the lockdown.)
Beyond coding, I've mostly been putting back on all the weight I lost over the past two years. I'll start exercising tomorrow.
I've been working from home on a sometimes unstable connection, so I've been using Mosh a lot. It was a bit tedious to update the security groups manually whenever my IP changed, and I'm also in the process of learning Rust, so this looked like a good project. It's not yet operational, though.

The plan is to start with an Android app and a macOS app to solve for my personal use-case and add more platforms in the future. The primary motivation was the lack of good markdown apps that sync between Android and macOS. Bear notes is the closest, but they don't have any plans of creating an Android app.
Keycloak is a very good Identity Manager but the default theme is not easily adaptable. Making new themes also requires effort and a little bit of knowledge, which means additional time to invest in learning the platform. On KeycloakThemes you can find ready-to-use themes (for now one, more to come) that you can upload and start using in 5 minutes.
For many years I've had the habit of remembering and noting down my dreams first thing every morning. I wanted a place for collecting & analysing all these dream reports.
So I built this journaling app. It's a PWA that encrypts everything before syncing. For now I'm just testing it with friends, but I want to launch it in the coming weeks.
Now with that shipped, I'm thinking about some actual code projects. :)
- [1]: I took a Coin Pusher arcade game and put together some electronics and software to make it playable through a Twitch stream. I thought it'd be fun to make and an interesting idea (especially with people being stuck at home), but it hasn't really gained much traction. It's currently a functional "MVP", but I haven't gotten any players so I can't figure out how to iterate and improve it. I built it using NodeJS, C++, a Raspberry Pi, an Arduino, a 3D printer, and an assortment of electronic components.
- [2]: Rebuilt my personal website. I've been hoping to write more (mostly for my own sake). One of the things that was mentally impeding me from writing was being afraid of being incorrect. I like to learn, but I think I'm a slow learner and don't always get things right the first time around. However, I tend to usually figure it out. I think writing could help me through that process (and potentially other people that are learning as well), so I think it'll be easier if I approach my writing with that perspective. I built it using GatsbyJS and its hosted with Netlify.

I’ve been writing and linking about flights from and to reality through art (usually videogames) at https://hypertexthero.com which is now published with a [static site generator][1] and no JavaScript other than [HTML Form File to Txt][2] to quickly create a text file for posting. The site design and format was inspired by Daring Fireball, and I aim to release it as a theme soon.
During this time I discovered [Focus Writer][3] which is open source, cross-platform, quite nice.
Hoping people will come up with fusion power and other climate crisis [solutions][4] during this time.
Peace out.

As far as I know the engine wasn't used again, with most moving to a Doom clone. I think there's untapped potential in the ROTT engine, and want to show it off, while having the game still run on the original target (386/486).
So far the code analysis has been really interesting, especially compared to the Wolf3D engine that it started as.
As with any cool project nowadays, CodeSnippetSearch is powered by neural networks (six in fact - one for each programming language). The project is open-sourced and you can read about the implementation details here: https://github.com/novoselrok/codesnippetsearch This project started as a reimplementation of the models in the CodeSearchNet challenge by GitHub (https://github.com/github/CodeSearchNet/). I have reused their data and reimplemented the neural bag-of-words model in Keras. I didn't expect any improvements with my reimplementation, but I did manage to beat the baseline models by a little bit.
The search is still a bit of a hit-and-miss and I'm continually trying to improve it. If the match rating for the top result is below 50% it will most likely be irrelevant.
I also did a couple of Show HN posts for it. Didn't get much traction with either, but it's ok because I think my next steps are to revise the landing page and get a more proper UI.
Feedback is very welcome!
I also finished knitting a sweater -- my second overall, and first time not working from a pattern. I had to redo the yoke three times (the torso and front/back panels of the yoke are lace, so I wanted to integrate the decreases in the lace pattern), but I'm really satisfied with what I ended up with.
Working on this with my girlfriend, mostly for fun and to learn something new. We're using Webflow for the site, Airtable as the backend, Zap to help stitch a few parts together, and Twilio for SMS support.
It's a video editor with some really cool effects/transitions. In quarantine, I've been re-vamping the UI to make incredibly easy to create videos.
I hope to have another version in about 1 week where creating videos will feel quite seamless ;)
(Adding media into your video project has been hard - which is what I'm fixing right now.)
Easy, secure REST API for your SQL database (PostgreSQL and MySQL/MariaDB supported). You pre-define queries and get REST endpoints for them with token authentication.
I build a lot of side projects and got tired of always having to setup an API backend for each one that I wanted to use an SQL database with, so I made Seamless.cloud for myself. Maybe it will be useful for others too?
I just wrote a short post about my experience so far: https://harald.co/2020/05/15/simple-free-website/
Figured out how to properly use the bread machine (making approx 1 loaf a day, currently have carrot cake going).
Currently working on a proof of concept for a desktop version of a web business I own.
8-year-old is super obsessed with primitive tech and has been digging up clay out of the back yard. I imagine we'll be making a kiln this weekend and eventually bricks.
I've started posting podcasts showing how I use the magician's toolset to invent new technology that's focused on doing the impossible in a way that meets users needs and dreams!
I also launched a webapp for me to keep track of the tricks I know: https://trick.app
Here's a demo: Daft Punk's - Da Funk remix: https://www.youtube.com/watch?v=OdQQJPpL6Lo&t=138s
It uses Kotlin scripting as live-coded sequencer and SuperCollider as sound engine.
We also decided to farm chickens (for eggs), so we bought a havel - another couple of hours spent on assembling. As we never did this before, we are grokking the web looking for something you would call "chicken farming for dummies".
It's called PerfBeacon (https://perfbeacon.com/), and since quarantine started I've had time to add a free tier, test an implementation in Docker (rather than AWS Lambda), and start a couple of integrations with Netlify and Vercel.

Wasn't paying too close of attention to Monogame for the longest time, so the XNA code stayed dormant for years, but then I finally sat down to see how hard it was to port it to Monogame and I had it running in 24 hours. So I decided to sit down and rework and clean up the UI, upscale all the graphics (requiring me to remake them in Illustrator, since I originally made them in 720p in Photoshop), adding support for up to 6 players, support for localization to more languages, adding in-game achievements, adding new game modes (still trying to get a single player mode that feels good), support for larger maps, and recently trying to get socket programming working so I can add IP-based online multiplayer (maybe eventually with a server for a later release, we'll see).
Also debating switching the graphics to 3D, but that may be too much, and I'm not so confident I can rewrite shader code for each platform. I had trouble as it is getting a line effect I had in XNA working in Monogame on Windows.
Planning to release it on Windows and Mac first, and then expand out from there. Probably mobile (I released it once on iPhone but it was a port to Objective-C and that code is now ancient), then hopefully get it on the Nintendo Switch before the next console generation, then probably Playstation and Xbox.
I used it as an excuse to try some new techniques in Javascript and I am pretty happy with the way it turned out.
If you want a 10 minute distraction:
Basically our hourses are 1-3 orders of magnitude dimmer than the outside; this is not good. Ben Kuhn's approach was to buy a big 30k lumen LED bulb for $100. I am doing a more DIY approach with a number of small LED COBs. Each finished module will output 13.5k lumens for a bit less than $100 (so multiple will be needed per room), but it comes with a number of benefits:
- The light is extremely high quality, almost the exact same as sunlight. Fluorescent bulbs and normal LEDs do not give off the full spectrum of visible light we get from the sun and incandescent bulbs. In fact I tried growing some plants indoors a while ago, and even though they were seemingly well-lit they ended up dying due to a lack of light.
- The light can be dimmed to warm. Each module has four LED COBs. Three are bright white and put out 13.5k total lumens. The other one is a warmer white which should be useful at night - like IRL flux/redshift. And these can all be dimmed smoothly from 100% to 1% brightness.
- The modules are controlled with an ESP8266, so they have WiFi. Aside from controlling them via a phone/computer, I am going to set up a Raspberry Pi running some timed scripts to automatically adjust them. For example they can all turn on in the morning as a natural wake up alarm (I have a separate alarm clock project I'm working on to give this a normal physical alarm clock interface). And I'm going to investigate using PIR sensors to make them automatically respond to human presence.
In the end this method is a bit more expensive than just buying high power bulbs (and more expensive than buying normal bulbs, but you would need like 70 of them in a room to match the total light output), but it has a number of seemingly useful advantages. Right now I'm working on the second (and hopefully final) prototype; the first was electrically OK but had thermal issues (LEDs still get very hot!).
It's an interesting break from normal software engineering. There's a huge emphasis on getting it right, and on getting it right the first time. Since there are a couple of amps of power running through the system, it needs to be well designed and safe from the very beginning. And $6 shipping every time you order from DigiKey punishes iteration heavily, since if you're making small iterations then your shipping will be much more expensive than the parts. I spent probably around 60 hours researching before making the first order. After finding out that the thermal solution was inadequate I spent a bunch of time theoretically fixing that and finishing up every single loose end (up to well over 100 hours total now). So now my second order will very likely result in a 100% complete, functional, and safe (I think!) product.
The only thing left is to design a lamp-style enclosure. The module is small enough to replace a lightbulb in an overhead socket, but the wiring would need to be changed slightly and working through a small hole in the ceiling is not really practical.
I'm working on a console-based RSS client in Haskell. The original plan was to implement the basic functionality of Newsboat (which currently is being rewritten from C++ to Rust).
It's still raw, but I already started using it as my primary RSS client. Right now it can fetch feeds, display them in a nice menu, maintain read status, open urls in a browser. The next features I'm going to add are support for configuration files (everything's hardcoded now) and tags + filtering.
--
Newsboat had a few problems inherent to C++ (like occasional segfaults) and the TUI library it used. Knowing about these, I started googling for alternatives written in a higher-level language. And spotted the announcement [1] of the Newsboat author, saying that he's going to rewrite Newsboat in Rust. When I read that, the rewrite was already going on for months with still no end in sight. I thought, "Heck! I can implement this in Haskell in a few days!" By now I spent about a week of full-time work on the project (spread over months), and got a bare working prototype.
My estimate was too optimistic, of course, I didn't foresee all the difficulties I encountered later and all the things I had to learn. But still, I think if I spend one more week on this, I can get a fully-featured and polished RSS client — Haskell makes programming a lot cheaper.
I don't have much new to show yet, but the jam version is available at https://kroltan.itch.io/farm-fortress-2
It's a strategy game focused on production chains and resource management.
It's still a work in progress, but I've gotten a lot done on it and looking forward to releasing it this Summer! You can check it out at https://caretakerdb.com if you want.
I went back-and-forth at first on whether now's the time to launch a commercial side project like this, but with some uncertainty about the security of my VC-backed day job, I settled on this being precisely the time to have something of my own going.
I also play a bit of Summoner [0]. Perhaps I can finally finish this game, which I couldn't when I played it a long time ago.

Initially hacked together the bones of this back in October lats year to fix frustrations with my chalk board (well, mainly with my writing and organization). Lockdown gave me the chance and impetus to focus in on this with lots of help from my awesome co-workers. We launched yesterday - but still have so much we want to add to this.
I wrote up some background here: https://www.suckingstones.com/2020/04/28/brewboard-backgroun...
If you're a brewer (particularly if you use Brewer's Friend - since we already have an integration in place) please give it a try and send us your feedback. We want to take the chalk board to a new level. Oh, and here's my board: https://brewboard.app/boards/MGMvq-wZ1ks4
The stack is Django, Nuxt.js and PostgreSQL (also MySQL and SQLite are going to be supported). For this project I've been learning Nuxt.js and Kubernetes. Normally I work full time as a full stack freelance developer, but due to the corona outbreak I've lost one of my biggest clients. This resulted in more time for Baserow, which was already a side project for a while now. I would like to make a business out of this in the future because I really enjoy working this.
I've looked online for resources and I've found a bunch of Youtube videos that go over the high level concepts:
1. https://www.youtube.com/watch?v=GwIo3gDZCVQ
2. https://www.youtube.com/watch?v=njKP3FqW3Sk
3. https://www.youtube.com/watch?v=tPYj3fFJGjk
For reference, I have 0 AI/ML/DL experience but I having been coding for awhile and I'm familiar with Python. These videos are quite long but I plan to start building a small toy app to validate my understanding. I'm just not sure if I'm taking the best approach to learning these concepts. I want to start working with the various tools ASAP because I believe that I learn better by doing.
It is my first attempt at a product/business and has been a good learning experience. Also a good excuse to have Elixir & Phoenix a good. Long story short, I like them but miss types.
Probably a dime a dozen project compared to most things posted here, but it has an eventual use case for me, and it's fun :)
I also worked on helping prove to the UK government that open banking can help justify income for the self employed - https://covidcredit.uk/
Have a look at the project here: https://github.com/findthemasks/findthemasks Drop us a PR if you see something that can be better.
It's a week old now and I have around 2000 services listed.
This services rose from my own need to understand how to build something as cheap as possible. Working on this gave me the understanding how many services gives you a free plan which is good enough to solve a problem you care.
The quarantine forces me to think about it even more, and I think I've found the why, and how.
So I'm now building it: https://focussist.com/
Doing: lifting myself to hell and back and jump rope.
Building: Making maze generators in minetest (before moving them to minecraft)
And trying to figure out if I can find a function that takes two finite consecutive sequences with length N and M of natural numbers, which start by 1 (E.g [1,2,3], but not [1,2,4,5]) and give back a sequence which contain all the numbers starting from 1 up to the NxM, but not necessarily sorted without using the size of the sequences. So I want to number the cross product of the two sequences.
This crap is related to some programming problem I hit.
t = {1,2,3...} -- <- can be lenght
s = {1,2,3,4...} <- can be any length
xs = {}
for i,h in ipairs(t) do
for j,k in ipairs(s) do
q = f(i,j) -- <- I want to know if f is possible
to write
xs[q] = h * k
end
end
After being able to print I tried drawing. Both blender and fusion 360. Blender for organic objects and fusion 360 for practical engineering objects.
It's a really fantastic hobby and you'll be able to produce a lot of physical objects instead of only writing software.
You can follow along with my progress here: https://twitter.com/zackmichener
Work continues on sqlc, my SQL compiler side project. I recently released v1.3.0, which mainly consisted of big fixes.
I’m really excited about the in-browser playground I launched at https://play.sqlc.dev. I hope it gets more people to install sqlc locally.
So far only a few people know about it and some of my friends are using it, but my goal is to keep it running and use it myself even if nobody else ends up using it. It is very cheap to operate and I use it as my own personal bookmarking and media upload service. Beware: work in progress!
Here is a video that the whole family worked on for a school project a few weeks ago: https://youtu.be/QHmkRBIzUMs
Been wanting for a long time to rewrite it into something usable by others. Been doing that rewrite during lockdown.
All this reuses existing tools and conventions, is lightweight, shell-completion friendly, easy to learn.
Also, written (again) a game for the 8bit computer Amstrad CPC of 1984, in clean modern C on a C compiler that understands most of C11. With optimized assembly for time-critical parts.
Both started earlier this year, got more time during lockdown.
I might offer a "show HN" for one or both. If you have any interest please tell.
I don't really need to do this (ought to be looking for a job...) but now that I have quite a number of different review datasets to play with, a framework that lets me spin up 10+ processes across the 5 machines I have at my disposal will make short work of most the sets. I will need the uni's HPC cluster to deal with the Amazon dataset, though. Using dask will surely help with that. Then it's writing yet another paper... Not being allowed to go outside is rather motivating.
This is mostly because I have a personal need for this and I would like alternatives to existing movie recommendation services, but I may make it available online if time permits.
A second step would be to introduce an example critiquing aspect, allowing for interactions like "show me movies similar to 'Crimson Peak' but with less horror".
All of this is based on the MovieLens 25M dataset and an accompanying article (http://files.grouplens.org/papers/tag_genome.pdf) describing a recommender called 'Movie Tuner' that is no longer available.
It will be fun to tune the recommendations based on my own preferences. For example I don't need an algorithm to suggest movies that have the same actor/director.
Initial results are encouraging.
I rented a server from Digital Ocean, installed nginx and Go, and wrote a web server. No frameworks on the front or backend, just HTML, CSS, and a couple of small scripts. And I wrote my own authentication and admin pages to manage everything from the browser.
But exactly the opposite happened. After a sharp collapse in visitor numbers in the first days of the crisis, they shot up again. More than I knew from before. That was astonishing but in retrospect logical: because here in Germany there was no real curfew, only a ban on contact with other people. So people probably thought: before I lounge around at home, I'll do something for my health and fitness. You can also tell from other comments here that fitness projects have worked. That motivated me to do my project even more intensively, because I realized that it is important to people.
It's not public yet, but let me know your thoughts about the idea.

I used to work at a tech giant, where the data team relies a lot on native Spark in Scala. I've always found the combination quite pleasant to work with. However, I did miss Python's faster startup time, dynamism and REPL, especially when doing data cleaning and exploration with no intention of putting it in production.
Now that I'm doing my own thing at a much smaller scale, I naturally gravitated towards Python's data stack, namely NumPy, Pandas, Sklearn and Dask. However, I found myself missing Spark's consistent SQL API and performance!
So yea, I've been wanting to use more Clojure for work and set up a Clojure shop. During the quarantine, I find myself having more time to do focused work. I thought this would be a good opportunity to convert some of the data wrangling stuff to Clojure!
I'm a CPA working as an external auditor for public companies filing 10-K financial statements. Looking for a job in public accounting is hard because audit firms do not have many differing characteristics. The one thing that is different is their clients. Clients are required to disclose their auditor, but obtaining a list of clients by firm/location is very hard.
My app uses public government data to plot US public companies on a map, and includes details on the firm that most recently audited their annual financial statements.
The data sources are: 1. a listing of all Form APs filed to the PCAOB (auditor-client relationship data), 2. SEC company data from the Corpwatch API database 3. Google search API for company locations
I only had a few courses in college concerning analog circuits, but if you understand the principles, it's easy to learn from the schematics available on the internet.
So far I've been exploring the use of MOSFETs - I found that the 2N7000 transistor is as cheap and abundant as BJTs, so I'm using it.
This type of transistor is less predictable and has a more complex working principle than a BJT, but with that come additional possibilities.
My last non-idiomatic-but-working design is a MOSFET-based A-class buffer that maintains an optimal operating point using a BJT differential amplifier as a comparator for the feedback loop, maintaining the DC output before the coupling capacitor at exactly half the supply voltage.
It's not linear, but that's the idea - if you plugged in a guitar to it the difference wouldn't be really noticeable, but doing the same with a bass should give a "sweeter", enriched with low harmonics tone.
Online but still under development: https://dotdot.im :)
I often see an idea that help solve a problem that I was stuck. A few days ago, people start to shares those ideas that helped them, so I created Inspired Ideas that you can learn from other experiences

You can create a Taaalk and invite any number of people to join it using an invite link and code. If you don't have anyone to Taaalk with you can leave your details on the Start a Conversation page.
Some friends and I started it a few years ago and then stopped, so I thought I'd rebuild it during quarantine.
Some of the old Taaalks are on there, e.g.: https://taaalk.co/t/how-to-think-about-chess
It's the first app I've ever deployed to production so it's been great to learn about servers and hosting.
I'm also rebuilding my website with Hugo. Feedback welcomed: https://www.voska.org
I'm also just starting to help my fiance launch a consultancy on remote teaching. Crossing my fingers that goes well!
I know, very generic :)
It's currently in closed beta (very closed) but if you're really interested, I can add you to the beta.

Right now I'm trying to figure out how to speed things up with multiprocessing (Keras doesn't play nicely with that). It's definitely a proof-of-concept project as opposed to something that's a enterprise-level tool (otherwise probably wouldn't write it in Python heh). Mostly I just wanted to make a sick-looking CLI for once.
Also learned how to cook properly, and addicted to learning all the nuances of heat, acid, fat, etc.
Actually started just pre-pandemic, so the timing has been quite interesting.
And yes, also lots of bread.
Anyway my quarantine side project has been my little SVG icon manager that let's you easily "batch" update color and size for icon sets and then drag, copy or export them to whichever format you want.
It's called Nonsense :) https://play.google.com/store/apps/details?id=nonsense.twa&r...

I wrote the guide to myself, but I emphasized the importance of dependency manager in the post: https://sayzlim.net/setup-macos-web-development/
It becomes much easier to learn a new framework knowing that I've installed everything correctly on my Mac. No more struggling with permission errors.

I got a very cheap one off Amazon, and only through dint of my prior musical experience (bass 10 yr ago, violin 30 yr ago), was able to put it into a decently playable shape.
It's a lot of fun, but VERY hard! New physical skills, learning a new clef.
2) welding my staircase railings and adding random bits like wheels, gears, old wrenches, a chicken-grill...
3) finishing the workspace area off for #1
4) sundry home repairs et al.
5) alcoholic beverage consumption in amounts previously considered immoderate. (not sure if this a hobby)
I built an electron app for organising and watching saved movies. In my part of the world, a lot of people still rely on external storage devices to share movies and music.

It's a simple site that features some links you might find handy during the lockdown. I've tried to put together a list that doesn't feature obvious choices.
I used Vue w/ Gridsome, it's hosted on GitHub with Netlify handling deployments. Honestly, it's been a dream to develop on. Gridsome is very user friendly, and I learned about GraphQL while making it (something I'd been meaning to learn about for a while) Using Netlify and having 'git push' automatically kicking off a build and a deploy without me having to do anything else has been so convenient. I'm definitely going to use a similar stack in the future.
Also enrolled for the science of well-being course on Coursera last week. Eye opening in some aspects so far!
It uses a fork of gifsicle compiled in WASM to produce highly optimized GIFs really fast. It supports trimming and cropping the end result.

It's an open source, simple (all metrics on one page), lightweight (1.4 KB), no cookies (no need for cookie banner) and no private data collected (no need for GDPR consent) alternative to Google Analytics.
The code is on GitHub https://github.com/plausible-insights/plausible/
Rather than track people surreptitiously it's completely public and voluntary. It allows for feedback to let people "+1" items on several dimensions (basically a big bag of emotional adjectives) and I want to rank the "truthiness" of facts, from physical laws and math (at one end) to opinion and interpretation at the other, with a (metaphorical) low-pass filter for BS and crap.
All information on the network is public, there is no walled garden or silo. The idea is to think things out together, in public, avoiding repetition and noise.
1) Automatically generate unique task IDs for all created tasks. (e.g. TA-12)
2) On push in Bitbucket/Github, post a notification in the Asana task that is mention in the commit message. (e.g. Changed login form to fix TA-12)
If anyone is interested hit me up! I'm in dire need of some good feedback. :)
Working on the 3rd ...
The previous iterations were built years ago using CoffeeScript, Grunt/Gulp, Jade, Stylus, etc. This time around, I went for vanilla HTML/JS/CSS, no transpilation, no bundler, no build step at all (and no frameworks). It's been a joy. I'm using the TypeScript compiler in VS Code for sanity checking and might add some JSDoc to leverage the type checks even, but for now it's quite nice as is.
I've also enjoyed building up a Discord community for it all, got almost a thousand people in there now and it's a lot of fun interacting on a daily basis.
I did get some extra time because one of the few things that were actually closed down was my Aikido dojo. But mostly I exploited the fact that friends in Italy and Belgium could not go out at all and... I started an online RPG campaign using Discord as a platform and Mini-six for the rules.
We are having a blast - I hope that the players will like enough to keep playing even after they get back to a more normal schedule in their life (me, as the GM, I have done some up-front investment in preparing lots of content and so I think I will be able to run it even when I go back to 3/week practice).
The e-bikes I've seen offer a small motorcycle in disguise, but what I want is a set of superman's legs, while not being a superman.
Generate a unique whiteboard and share with a friend to see it in action.
We were struggling to conduct software architecture interviews since going remote at my job because we no longer had a whiteboard, so I built InterviewBoard to fix this. I've been surprised by the ways people have used it. I originally anticipated people would only use it for software architecture, but data scientists have also told me they find it very useful. I'm still currently allowing as many free whiteboards as you want. Hope you find it useful! If you have any feedback I'd appreciate it at aking@interviewboard.io
I started by putting some freeze-dried meat into a food processor until it became a dust, then I started adding some other ingredients for flavor/smell/consistency. I was really happy with the results, so I thought I'd try selling them! So far just a few sales, but I haven't done much marketing to this point.
It's my first book, and I have to fight a lot of impostor syndrome to give nontechnical advice (because its context dependent and who am I to give it). But the feedback for my prior writing indicates there's some sort of demand for this, and I do believe that the "soft skills" side of early dev careers aren't talked about enough.
There's a lot of "break into tech" and then "go from engineer to engineering manager" content out there. I'm trying to fill the space in between. We'll see how it goes... aiming to launch June 1st.
Sorted and deduplicated all my photos.
Set up backups for all my important stuff using Restic to BackBlaze B2.
My wife is due to have our first child in six weeks and she is keen for our children to speak French and English.
Besides all the benefits of being bilingual, I mostly fear my wife and children will tease me in French with me none the wiser!
As the name suggests, this web app is meant to help groups of friends play some common party games (Cards Against Humanity, Taboo, Poker, etc.) over Video Chat.
I’m an engineer exploring “the dark side” and saw a lot of classmates losing internships because of covid.
Contrary to the bad rap I feel that MBAs get amongst hackers, I’ve been pleasantly surprised how kind, scrappy, and effective my classmates are when applied to the right work “around the tech” e.g. marketing, running numbers, and fuzzy stuff that is important as companies grow.
Grew larger than we expected to a lot of other schools.
One disappointment: I wanted to call it “Hire the Dark Side,” but couldn’t find a single MBA who understood the joke!
I also read some books, too.
Also, I have a comment about the pagination on Hacker News. I will want to know how many pages there are in order to quickly skip to the last page. (Really, just implementing NNTP would help. It has a high water and low water number, to easily find the oldest and newest messages. It has a lot of other benefits too, including user-defined sorting, offline mode, etc.)
It's free to use till I figure out if people really want this tool.
I'm also trying to get Remake off the ground: https://remaketheweb.com/
Currently working on 3 intro blog posts, as well as coming up with a sustainable pricing model.
- Slack RTM bot which picks up my morning and goodbye messages in our channel and stash the duration into our time registration system so I don't have to do it manually. Using Slack library for Go, compiled to C library using gccgo for C ABI compatibility, then using Zig's cImport functionality to develop the bot in Zig (because why do it the easy way)
- mbedTLS bindings to Zig (Zig can generate alot of this out of the box, but I'm tailoring it by hand)
- HTTP/1.1 client in Zig, ties into the mbedTLS bindings I want to provide TLS support

Not done yet, still little issues with flow state, for example, if I have a dual range slider in react with clearly styled and labeled beg and ending sliders values, how do I drag one slider over the other and force swapping the two but continue the UI motion. Currently I'm just overriding the event target.

I imagine this being used by people to reconnect with acquintances that they really admire, who will naturally start new projects / bands / companies / skateboard crews after learning of each other's mutual admiration.
It's super early stages, but would love to hear from you on hello@gethelden.com if you think it's interesting :-)
Like my early software, I expect that my current novel will eventually collapse under the weight of inherent lousiness. I will then start again and do better.

I'm building a google play music clone (a music locker), It's not ready yet but by the end of this month, the beta will be out.
I had no idea how much of the world is built on Python.
Learning how to use computers via SSH alone has been fan-TAS-tic. I should have started long ago.
Also, bread is great. Keep it up.

The end goal is to provide better secure boot tooling for people. This is exemplified by my sbctl project which aims to make it silly easy to create keys, and sign stuff. Currently it shells out to sbsigntools, but this feels awkward and I'd enjoy some better integration without having to call out to C-code.
Session focuses on these points: - beautiful design. - analytics: what you worked on and for how long. - introspective: after each session, it'll ask you whether you got distracted. If so, why? - meditative: breathing in and out once at every session.
I have bought the domain; but not yet designed the websire so progresses could be seen on https://www.twitter.com/philipyoungg
I wanted to build, as I call it 'Global Creative Community' called Branding Pavilion which is an online directory of companies, events, job offers and interviews from the digital industry.
The idea behind this project is to help clients reach digital/marketing/software companies and create an online community.
Software stack of this project includes: Bootstrap 4 as a CSS framework, Vue.js for logic and functionality, Firebase for database and backend, Stripe as a payment method, Cloudflare for protection and security.
Also trying to clean up https://geo-yak.com and https://yak-mu.com, which are IP Geolocation charts for visitors, and SQL analytics for Stripe. I made both to scratch my own itch, but trying to market them a bit too.
2) Built another cordova app which bundles a load of videos I use as reference for training (Okinawan weapons [2] kata), need to compress the videos better, the app came out at 800MB+.

Stairstep analog from Rob Walling (https://robwalling.com/2015/03/26/the-stairstep-approach-to-...)
I also ported a set of APIs I wrote in Ruby over to Python so I could finally learn Python. Mission accomplished!
Abstract: This book is intended to be a tutorial that teaches the functioning and example uses of the Common Lisp condition system. It is aimed at beginning and intermediate Lisp programmers, as well as intermediate programmers of other programming languages. It is intended to supplement already existing material for studying Common Lisp as a language by providing detailed information about the Lisp condition system and its control flow mechanisms, as well as description of an example ANSI-conforming implementation of the condition system.
It's a central place to monitor, issue, renew, revoke your Let's Encrypt certificates.
Also starting to work on a slack alternative for small business. I've found alot of companies are using Whatsapp group chats for business and I think there maybe a market. You can read my initial thoughts here. https://hobochild.com/posts/chat
(I set aside 2020 to work on this, but quarantine definitely created much more time for it)
I also made a fully incremental static site generator, but this will probably never be something I can show off because it isn't cleanly divided into "library code" and "configuration for he specific sites it generates." It has no non-incremental mode. You might say "Performance is a non-issue for static site generators!", but incremental builds means you can make expensive operations like pngcrush part of your build without having to wait forever.
I'm also working on Crisp https://github.com/huumn/crisp which is a cryptocurrency written is Lisp. It's currently a toy meant for exploring, but what I want to do is have the transaction language be designed around spawning subchains. A blockchain for creating blockchains.
How can I secure this collection for my children, when I have passed on, how can I ensure that they can access and get a copy of the files?
I used the change in routine to put spare time into launching a specialty coffee indexing site[1]. I've been thinking about it for +1 year.
Still working on the backend and the ultimate goal is to tell you when harvests from producers you've liked before are back on sale (i.e. I liked this coffee last year, what might I like this year), and build a kind of engine to recommend coffees.
(It's also a testbed for ruby continuous deployment with Docker!)
I'm using Go for the backend and React on the frontend, along with MySQL and NATS for message queueing.
I'm too afraid to go shopping, and I don't need to, because I bought a lot of long-life food, including milk. But I missed joghurt, so I started to make my own, and it's great!
- GoCache - An LRU based cache server inspired by memcached.
- gKeeVee - file based key/value store
2- Working on an Indexing tool which will be based on Inverted Index.
3 - Reading books.
4 - Learning Rust.
5 - Trying to learn Farsi. Still looking for better resources.
Just a simple (click and go) video monitor for your pets/baby. Click "share" on one phone/laptop/tablet, and you can connect and view it from another. Video doesn't use bandwidth unless you're actively viewing, and doesn't go through our servers unless you require TURN (rarely).
Duobiblo (https://app.duobiblo.com/) allows to practice a language showing chapters of the bible side-by-side with a language you already know. I learn Portuguese currently on Duolingo, which inspired the name. If a browser supports the Web Speech API for the given language it is also possible to let the browser read the text.
It does prerendering of React/Vue/etc SPA similar to https://prerender.com. It functions as a cdn however, so it is a simple dns change instead on integrating it into a server.
It's not as fast as I would like and it's not really tested either. It's gonna be free for a long while. I keep meaning to clean it up a bit more so I can publish it on github
I'm glad I did, because literally every job I've applied for has had some kind of Codility or HackerRank style test - even bog-standard developer jobs have asked DSA-style questions. Yesterday, I was asked a Dynamic Programming question for a full-stack developer role at a bank.
It seems like these kind of interviews are becoming the norm, so I'll probably spend the rest of my furlough time working through DSA courses, grinding LeetCode, and doing daily Codility tests for different companies.
Also I'm using a lot the timer with my Apple Watch and I needed something faster than the built in timer and I can't every time use Siri. So I made one fast is more fun & faster as well with multiple mode: https://primetimer.app
Also a simple music streaming server which caters exactly to my needs without taking care of others (now writing a client for it)[1].
Plus learning godot to write a small 2D game with my brother's band :D
And learning Georgian letters (they are beautiful).

It uses Nodejs, socket.io, chessboard.js, and Jitsi. For a while I was using a 3rd party chess embed but that didn’t give me unique rooms so I rolled my own w socket.io. Now I just have to worry about glitch.me quota. I figured if it gets popular I’ll just do paid glitch.
About 30 HN community members have signed so far. Post your projects and ideas and email/chat/Zoom with the people you find interesting.
I'm putting it behind a form so that recruiters don't jump on and spam message everyone. Keep building + stay safe y'all!
I'm also planning on looking into modifying an old digital clock radio I have with and ESP that uses NTP to keep time more accurately but I haven't gotten very far with that yet.
The lockdown is really only half the reason I'm doing these projects now. The other reason is that I moved to a bigger apartment earlier this year so now I actually have space to hack around with this kind of stuff.
Once I've got that I'll play around with the firewall. And then get an actual external working address. But I think I want to keep that ULA.
It's super simple stuff and I move amazingly slowly.
It's also sad compared to other people in this thread who are starting businesses and creating software that will save the world.
Why I am doing this:
- Improve my business (learn about different business models) - Improve my product sense - Hearing good CEOs talking at their investors is a great lesson.
What I am building:
- Use Azure to automate stuff and set up notifications for events I am interested in.
- Use python to backtest strategies.
I wrote this thing last week https://medium.com/@davinci260/why-only-buy-when-you-can-als...
I have created it with Django, nginx and Postgresql. It is hosted on Hetzner, which I couldn't recommend enough.
I had an idea to create a website that shows you how much sugar is in a product. I was too excited and bought the domain name:
The domain name stayed dormant for 6 months, until the quarantine. I created a minimal working product with no design but it works.
This product already exists in the market. But all apps fail at nailing two main problems.
1 - Seamless fast search.
2 - Graphically conveying the sugar measure.
The first one is what I really worked on, to make it fast and intuitive. Still needs improvements. The second one is still a work in progress since I am no designer.
It should enable yogis to find suitable online classes but also help out the studios to guide customers to their online offering. Lockdown is slowly lifted around here but there is still a limit on the number of people allowed in a yoga class.
Stack is based on flask. Took this quarantine time to learn more about container-based deployment; still battling a bit with cold-start times on google cloud run ;-)
Professionally, two different clients have postponed their projects until October, which is getting a bit worrisome. Some members of my team have been advised to propose summer projects that will help automate our engagements, because Q3 will be light, but then Q4 will be a deluge of chaos and demand.
I plan to publish every Friday.
Now contemplating a group buy for general public/businesses with the re-opening to top off the work. https://bit.ly/groupbuymasks
https://purchasepoint.landen.co/
We've made a few apps in the past that monetize with consumable purchases (specifically things like virtual currency, extra swipes for a dating app, etc.) and realized the backend we wrote each time for storing user inventory after making an in-app purchase was almost identical. PurchasePoint handles the details of Apple StoreKit and Google IAB transactions to track user inventory for you.
Hand-curated remote jobs in product & UX, from across the web.
Of note: the site and its twitter feed (https://twitter.com/remotivocom) are generated by 2 python scripts which run on a Raspberry Pi under my desk. The 'database' is a Google Sheet and the 'host' is an S3 bucket, both of which are read from and updated every few hours by the Pi.
The site also features no analytics and calls no third-party scripts.

Over the years spent reading HN, I noticed that some comments with the best information ratio, were the ones based on data. I wanted a way to quickly find them, otherwise I would miss them.
Surprisingly, reading that feed has started to be part of my daily routine. But I am still toying with features I have in mind. Feedback would be appreciated !
https://death-proba-website.appspot.com/
The app just gives you a comparison of covid death probabilities to skydiving and other activities depending on age and sex. Can be helpful to make personal decisions.
For instance that a 40-49 male, if infected, has probability of dying equal to 75 jumps of skydiving.
(Please read disclaimers on the website)
Current status:
* Works great on a home network, but I still need to work out point-to-poin tunneling through the Internet.
* Nearly done working out a separation designation of personal devices from different users.
* Currently working on test automation via service simulation and browser simulation via Microsoft/playwright.
* I plan to allow end-to-end encryption via key sharing, but I am not there yet.
* I plan to allow remote application execution for devices under the same user account, but I am not there yet.

The end goal is to generally improve my ability to prototype PCBAs in my home lab, starting with a CAN gateway module that I've been designing. I'm hoping to be done with quarantine before I get to actually use the reflow oven.
It allows you to create a reminder for someone else, then provides a series of messages, starting with a heads up, the actual reminder and a follow up asking if the prompt was completed. The user can reply and the loop gets closed, you get a response saying the task you assigned was completed.
We've had some interest from developers in using the core api. So, we're using this time to convert the core platform into a api for developers.
Designed and open-sourced a custom CNC Aluminum Unibody case for an existing open-source split-fixed mechanical keyboard PCB called the Arisu, similar to the TGR Alice.
Prototypes arrived in record time and definitely enjoying them as I type this.
The PCB can be quickly built by several prototyping companies and available at: https://github.com/FateNozomi/arisu-pcb
Planned software features:
- detect which room I’m in by strength of various bluetooth devices
- default screen controls Sonos volume in current room with one rotary encoder, light levels of Hue lights with the other
- pushing the encoders to control other rooms
- scope for adding more screens a simple configuration schema
Current status: hardware prototype (inc. case faceplate working on bench power supply, software about 15% done
Incredible reading all these! Definitely motivating to make a bit of progress this weekend :)
A full time work from home setup with children at-home is already draining energies
We actually already started renovating before the lockdown. But since there are not so many leisure activities anymore, now we took almost all our free time to focus on this private project.
Some days ago I started documenting it on Instagram, if you want to check it out: https://www.instagram.com/gewoelbefichtelgebirge/ (texts are in German).
The Agora is an enhanced social contract for the internet: https://anagora.org/wiki/Agora
The site itself is just based on MediaWiki, no ad-hoc code for now. In the future I hope to be able to port it to AthensResearch: https://github.com/athensresearch/athens.
https://infinitower.suldashi.com
There are no mobile controls at the moment, and movement is done via WASD keys. There are not many features at the moment since I’ve been focusing on the core engine functionality, but the development process has been very rewarding and educational.
I also want to use this material to write a series of tutorials or maybe even a small book.
I use Notes on OSX quite a bit (and GEdit on Linux...) for gists, reminders, cheatsheets etc... Mainly to re-use code bits and idioms I find useful. But then I switch computers / OSes quite a bit and I don’t have these notes with me everywhere.
I wanted to solve this problem for me in a way that was compatible with my usual workflow (copy / paste!).
So I built https://www.sheethub.io it is very Beta ATM, but if you find a use for it I'm happy :)
https://www.reddit.com/r/esp32/comments/g64w16/esp32_heartra...
It has not been validated by Google yet so you get a big red warning box, but its all client side code. Basically you get the interface of WhatsApp, but the messages are plain old e-mails. No support for attachments yet, but works perfectly otherwise.
I’m using it myself, its really pleasant to use. It makes e-mail into a less formal communication method.
Made with React & Tailwindcss.
Refine is the most interesting part, you are essentially editing the transition between two story nodes. The goal is to not add much, but make the transition smoother. Was thinking of capping the allowed delta in some way and requiring the original authors to approve the story "PR".
Our vision is to improve online teaching and learning experience. The first tool we are building is interactive presentations.
Education is very important and I feel like people forget about teachers and how they need to transform towards online teaching. I see a great opportunity in this fast-growing market.
What do you think guys? Do you know anybody that could help me share this idea with my target group?

Happy to host a game for anyone interested once I have functional internet restored. Stuck in France and connectively handicapped.
2) Baking cakes !
The best one yet is an almond chocolate cake which functions really well as proper-food-replacement.
3) On the work side I've been helping a few companies migrate to remote work. Improving organisational habits and behaviour so people see that remote can be a positive thing. Measurably.

Finally today, "Smart Sloth" is out on Product Hunt
Check it out and let me know your thoughts - https://www.producthunt.com/posts/smart-sloth
Smart Sloth is a task manager that helps you be more efficient with YOUR TIME. Smart Sloth uses the concept of timeboxing, which is to allocate a set amount of time to each task, therefore, creating a deadline which can increase the productivity of the user.
A noteworthy feature is that you can open a file by specifying the issue line.
"What do you like about Go?" when asked, I always answer, "easy to make a linter". Thanks to that, a bunch of linters are on the rampage. I've been wanted to try them on the UI in a casual way, that's why I made this tool.
- Putting together a leporello book
- Drawing colouring book(s) for kids and adults
- Not a side project per se, but learned how to work in SketchUp & Storyboard Pro
I used to store this info in a private wiki but I'm trying to find a way to do it properly in this format. I did it 99.9% for myself, because if I don't write things down then I forget them. But if it ends up being useful to someone else then I figure that's even better.
Started a different side project that attempts to create a large collection of newsletters:
Also learning more about Docker and Kubernetes to get a better sense of how the architecture works.
https://github.com/bpicolo/bulletin
I always find it fun to play with the limits of library ergonomics under language / ecosystem constraints.
I've also decided to redesign my Bookmarks app [2] recently - it's now one of my few designs that I'm really happy with :)
Now my project is a 1000 science per minute factory in Factorio. I'm 100 or so hours in. It is a game I'll recommend to any programmer: It exercises optimization, planning, testing, debugging, (coaching and collaboration if multiplayer), prioritizing right, and the balance of living with hacky imperfections while still not letting them overwhelm your design and grind everything to a halt.
We're now working on a Reddit clone that uses (again) React and Firestore (for auth and storage). It's just for education, not some planned product.
Now that I'm done (as of a week ago), I need another side project!
I had to pick up all the tools for it, and with those I'm on a kick for other craft projects. I have plans for some wooden climbing holds, a raised planter box, a little free library for the neighborhood, a bench.
Woodworking is such a fun hobby I didn't know I liked. I think it's because it's so tangential to tech.
Working with a friend who went back to the farm three years ago - for context at 40 he's the youngest person in the village - on local country cooking, sustainable farming, and promoting the area as an attractive break-away resort to breathe some prosperity into what is a really quite sustenance area.
And of course my non-side project that I decided to dive in to at exactly the worst time in a decade. Oh well. But optimistic on that.
2. split-polygon-demo (https://gavinr.github.io/split-polygon-demo/) - demonstrates the ~4 geographical operations you can perform to split a polygon into n roughly equal area polygons.
It's still early days but has the basic features done and the extra lockdown time is definitely helping build out the more needed features (you can't currently log in to your hacker news account but that's coming soon)

A simple git subcommand to keep your browsing sessions together with whatever repository relates to the session.
It's kinda trivial, but learned a few different things, mostly about git and BATS.
For example:
git checkout --orphan
It's tested, CI integrated, already in use.
I posted it a few days ago on HN and a lot of you had some great ideas and feedback. https://news.ycombinator.com/item?id=23030298
For now I'm keeping busy maintaining Pantry. You guys can check it out here! https://getpantry.cloud/
I also made this to play with SvelteJS for fun (UK government alert message generator): https://adamjaggard.github.io/stay-alert/public/index.html
I was working on a tongue-in-cheek web game called Political Campaign Simulator but it's parked at the moment.
It's a free way to distribute your referral codes and find new deals :)
Built a Product AutoExtract API, to extract clean product data from any e-commerce product page automatically, without any selectors or rules.
Most of the project uses off the shelf open source software: chrome headless and puppeteer for rendering, some computer vision algorithms tech and Cloud Run to slash costs for hosting.
Still training the algos, but you can try it our for a spin here: https://crawlify.io.
I've been making a way for reporters to cite covid-19 data and models through a url based citation system. All help is welcome ^_^
Everyone is welcome to join.
Additional plans include:
- home work help, maybe even proper homeschooling classes;
- setups for public school teachers to run their classes (I hear the current experience leaves a lot to be desired).
If someone has public school teacher contacts interested in experimenting with delivery, I'd love to talk to them.
(2) In march I spent way to long on an extension that adds Hacker News Comments to Goodreads https://chrome.google.com/webstore/detail/hacker-reads-for-g...
A platform that brings together people that are mentally struggling with isolation due to Corona with screened volunteers ("Hearts") that have a professional background in psychotherapy or social work (for free). The technical implementation is a huge hack right now but it works and our 50+ hearts are having video sessions with people from all over the world every day!
With TurboVar EmailBroker you can use a concise and uniform API to send emails using REST requests. If you prefer no-code, you can use a Web UI page.

A sort of sonic wallpaper to accompany work or daily activities.
Pulumi (like Terraform) stands up the t2.micro ec2 instance, configures nginx, and assigns the dns in Route53, and enable letsencrypt for https. Then tear it down when your down with it. I find it's much faster than the sass alternates, like ngrok.
- I'm making improvements to my small apartment brewing setup, making a lot of beer and doing some infrequent contactless growler deliveries to friends.
- I'm also playing with Phoenix LiveView[1] to make my own home brewing tools to replace the subset of BeerSmith(http://beersmith.com/) that I actually use.

Originally I wanted to see some Covid data with my own visualization, was thinking on D3 first.
Ended up with full TICK stack and Grafana, monitoring all devices I have at home and setting up alerts for all kind of silly stuff. Usefulness is questionable, but I learned a lot.
I have now some insight in the local area covid spread and happy to report, no new cases in my town discovered since a month \o/ (according to the government provided API)
Results are pretty good- I can take ~100-200 photos in a few minutes, import into Meshroom, and have a 3D model an hour later.
That eventually became https://mobti.me , and it's working well for us. If anyone else tries it, I'd be very happy to get feedback here or on twitter ( @mobtime_app ).
Jot Dot - Its a note taking tool I wrote based on workflowy's style of hierarchical bullets l, but I wanted to allow multiple documents and public sharing of notes (eg. My favorite Netflix shows or management notes etc.).
This link takes you to the public notes section. Not released yet so it's just my notes for now.
The idea is that restaurants offer reservation time slots, reserved parking spots, a menu item named after you, or really anything they want in exchange for money from diners. Ultimately, it provides another source of revenue for restaurants during these tough times.

https://github.com/eug48/cmd-frontend - a framework for creating customisable web-based GUIs for command-line tools, e.g. for administering Kubernetes
Started a YouTube channel, where I show how I work on AWS. Completely unstructured, the video are just a memory dumps in a hope to give some frame of reference to new AWS people, or to give some ideas to those that already know a bit of AWS.
ps. Bread, I remember the days I eat it :D
Why not use this moment as an opportunity to set up a common portal for announcing and finding research seminars, especially since most are now delivered digitally?
(This is being developed by a group of mathematicians, and I'm not the main dev, but still).
Tech wise its hosting it all in kubernetes and building the yaml dynamically. Right now focusing on database support. The challenge is routing from external locations securely.
'thrift stores' is a high traffic search term with low competition and low value traffic. I aggregated data from various store brands and websites and categorized based on locations data. The site is run on Python Flask framework on AWS Lightsail.
some examples : http://blog.boxi.chat
Also.. doing some paintings of internet people : http://art.tiyuti.com
Now I'm starting on a daily logging package.
I always want to know more about how people get things done but it's almost impossible to find high-quality content about it (apart from click baity resources like "what top CEOs do to be more productive").
It's free on the App Store in case you care to check it out: https://apps.apple.com/us/app/mick-tagger/id1490366427?mt=12
* Can work in REST or JSON RPC mode.
* Automatic routing + can be mounted as a Rack app, without framework, for unmatched speed and low memory usage
* Automatic documentation builder & Postman import link
* Nearly nothing to learn, pure Ruby classes

Prior to Covid-19, I barely got a time to work on it. Now I have plenty of time to work on it.
It's a website for Amazon's New World MMO that I started before the quarantine, but I have been able to work on it a lot during this time. So far the project enabled me to use and/or learn: Kubernetes, Discord.js, Twitch API, Nuxt.js (not the main site but an upcoming tool), and a whole bunch of non-coding tasks.
I'm trying to make it so that if you spin up multiple nodes it automatically balances the sharding over all nodes, monitors traffic and attempts to balance the work evenly.
It's one of my smaller apps but seemed to be gaining a bit of traction. Looks like this update has not helped gain new users as the last small update did... shrug
eurotripr.com - feedback would be great as i continue to work on this
The stack is basically python + streamlit and APIs for stocks data. More about streamlit here: https://streamlit.io/
I am not able find lot of public domain data of German companies. Any help is appreciated.
Tilting once again at the windmills of mechanical CAD software. I’ve gotten further than ever before in the coding, and in past attempts built up good knowledge on topological data structures, mathematics of splines, and solving systems of polynomial equations.
Also doing just-for-fun things like playing the guitar, working on a boat design (and learning strength of materials), biking, cooking, etc.
Still in the early stages so not much content.
I have been spending most of my free time on it for a while. It's a chrome plugin that shows random tweets from the user's like list, every time a new browser tab is opened.
A few of my friends have been using this tool for the past few weeks and the feedback is positive so far.
This is my first side project that has reached the launch stage.
It's been an awesome exercise and I've been quite impressed by the API available to extensions.
Currently I'm working on a) replacing a badly-cracked concrete walkway in my front yard with 2" flagstone which is native to the period in which my home was built and b) installing a 300 ft^2 brick patio in my back yard using a herringbone pattern while setting the pavers.
It feels good to get AFK, feel some sun on my face and improve the value (aesthetically and monetarily) of my home.
Haven't been able to bake any bread on account of how I can't find yeast in the grocery store anywhere...might give sourdough another shot.

On the technical side I am working on https://getworkrecognized.com - a work achievement tracker with email reminders (soon) and a nice interface to create Self-Reviews/Brag sheets that will ultimately help you with your next promotion/performance review cycle.
It's designed to make it easier for their clients to book a call/meeting with them, saving them the email ping pong to find a time slot that works for both of them.
Here it is - https://timeslot.co
Would love to chat with anyone who might find this useful!

It's a powerful unit converter for android. Right now, I am adding support for more languages and going through a bunch of feature requests.
But it's been really interesting learning the process of publishing an app. Each feature brings a 100 challenges but it's been fun overcoming every mountain.
Some small real problem I faced before: test\validate idea by counting how many times website visitor clicked the certain button. So I automated it with google sheets and some custom script\backend.
Landing is still in progress... Don't kill me for the language skills, English is not my native)
I wanted to make an all-online Meetup of sorts, a place where people could find and create communities that host events and get-togethers. Got the MVP done in about a week (thanks to Jitsi!) and then had to focus back on client work. I'm still considering next steps with it.
Also I'm working on a small server side analytics solution:

This is a hyper-niche pain point in commercial LED lighting energy rebate qualification where a manufacture has X number of skus and needs to predict which one will be the least energy efficient. The web tech determines the exact skus based on the technical input parameters given, saving manual time and redundant certified body testing.
So far I have a few users in the "trial" and they are really helping me to push it further.

I'm working on reaching the simplicity of Anki, while keeping more features like in SuperMemo, e.g. native support for incremental reading.
It's still in early stage but almost usable. I'm planning to push the repository on GitHub as soon as the last couple of to-dos are finished.
It's essentially a 2D rigid body simulation reskinned to look like a text editor. At the moment it supports basic commands like copy, paste, save, etc. Also, there are cheatcodes.
Started it on the side few months ago to help my own job search, there is still a lot of work left to improve data quality and completion, and also add more data points which will help engineers.
This was designed around the time Google and Apple announced their partnership, and the overall idea is similar (renewed anonymous identifiers).
There's a lot more I would like to build, but "real work" takes priority.
Besides that, lots of more involved cooking and baking projects to fill the time. I'll come out of this ready to be a stay at home dad!
Ideally, Apple would just release a FaceTime-compatible camera I can plug into my TV... but until then, I'm working towards a small HDMI connected device that I can control with my phone (running Jitsi).
I was frustrated there didn't seem to be any decent desktop-agnostic solutions that work in all apps, so I decided to give it a go myself.
Has anyone else been perfectly ok with the quarantine? I can learn, build, explore, and I don't even have to interact with anyone. I guess seeing friends is nice, but I don't miss it.

While dentists can't practice, it's much easier to get time with them to figure out what they need and don't currently have.
After that? I'd like to build up more of my (so far still private) personal website. Good excuse to learn more JS (and more modern JS). Maybe have part of the site be server based, learn more flask
I made a simple website for parents to browse things that your kids can get busy with, that's basically like a "list of things", but is organized into different pages (categories).

Building an MCU controlled constant current load.
I've been doing more of a product-ish role in my dayjob, so it's nice to do something (relatively) well-defined, where it's easy to tell if things are working, but still challenging enough to be fun.
When the lockdown started, I noticed I had a two food-related problems: 1) I was used to stopping by the grocery store more or less every day on my way home from work so I had no habit of planning ahead for more than a few days at a time. 2) In order to fit a week+ worth of food in my apartment, I had to distribute it between a few nooks and crannies which made it difficult to track what items I had where.
To help transition to my new once-a-week shopping schedule, I used Trello at first but that quickly grew unmanageable. So I decided to spend some time to build myself the right tool for the job. I realized other people may have run into the same issues I had so I tought I’d release it to the App Store.
is anyone else completely ok with quarantine? I'm not able to understand the need for social interaction, maybe because I'm an awkward dude.

Not really a fund, more a play on funding within. It's a framework for companies to let their employees start companies internally, to be spun out. Been slowly working on it through pioneer.app. Inspired by lots of projects at big companies that are great but just don't fit.
Since my gym closed down, I decided to make a clone of the app it had been using for posting Workout of the Day and logging results, to keep learning more Flutter and try Firestore for the first time - I developed it entirely on Android but this is me trying it on the iPhone Emulator for the first time:
https://www.youtube.com/watch?v=DvWJgZKj7cw
I've learnt so much from doing that, including implementing a signup/login flow with Firebase Auth, using Firebase Storage, how to get fancy with custom screen transitions in Flutter, how to implement, uh… that thing where a sticky UI element slides in/out as an overlay when you scroll down and up again - does that have a specific name?
I also went back to the basic Flutter VLC Remote app I wrote for myself a while back and having been adding as many features and as much polish as I can for the sake of learning:
https://www.youtube.com/watch?v=8eXJX4GVGhA
I'm in the middle of redesigning its controls, having just figured out how to implement a nice full-width slider which acts as a floating divider between the playlist and controls. I've also started breaking out individual Flutter things I'm learning into a Codepen collection (titled with phrases I failed to find help with when searching for these things myself): https://codepen.io/collection/nqpzvz
I also brought the React/Preact/Inferno toolkit I created in the pre-create-react-app days back to life after an 18-month hiatus, by finishing the Babel 7 upgrade branch I started in January 2018. Despite what they say about the JavaScript ecosystem, Babel and Webpack were still at the same major version as when I stopped maintaining it!
https://github.com/insin/nwb#nwb
It now has support for using the experimental build of React, the new automatic runtime in Babel's React transform which depends on it and the latest hot reloading implementation, which has come on leaps and bounds since I was away. Here's a recent demo of one of the main features I keep it around for:
https://www.youtube.com/watch?v=U0DwgoYq5WI
I accidentally took a head-first dive into TypeScript type definitions and back into writing Babel AST transforms - a particular phrase ("host elements") in a tweet about not being able to use HTML attributes in React gave me an idea for a new major version of a Babel plugin I had written to do basic class → className and for → htmlFor transforms on JSX attributes:
https://github.com/insin/babel-plugin-react-html-attrs
It now lets you use _all_ HTML attributes on host elements in JSX, and I ended up spending too much of a weekend forking the React type definitions off the back of it, to add support for using all numeric and boolean HTML attributes and transforming them to the form React expects.
I've always wanted to learn some Lua, as my kids love Roblox and I'd like to try making games in Roblox Studio with them some time, so I wrote my first ever Lua script to do a fun thing in OBS:

At the start of April, Twitter broke my extension for making it halfway tolerable, so I went back to maintaining that, making it capable of stripping even more crap out of your timeline and making the separated Retweets timeline it adds to Twitter more robust:
https://github.com/insin/tweak-new-twitter#tweak-new-twitter
I also dove much deeper into Gatsby than my previous experience with it of cloning and tweaking a blog template, as my wife needed to set up a marketing website quickly for a new business being spun out at her work. I've ended up with a setup which is easily reusable for the next site, easy to edit for non-technical users, and is zero cost for a really decent amount of functionality (mostly thanks to Netlify).
I even went back and resurrected my (OG) React Hacker News API client and added a new feature: a new story list containing every item you view the comment thread for, displayed in reverse-chronological order for ease of reading new comments on them:
Key points:
- It has a binary format (smaller) and 100% compatible text format (readable). Machines work in binary and convert on-the-fly only when a human needs to see or modify it.
- Supports all of the basic data types needed on a modern system.
- Supports recursive data.
- Future proof

HTTP/REST Interface for Desktop APIs
The Problem
Web applications are cheaper to develop and cheaper to maintain, than desktop applications. Many tasks which were considered too heavy for the web in the past, are implemented with web technologies now. Microsoft Excel Online and Google Sheet for spreadsheets, Figma for graphics design.
I have worked in large enterprises most of my career. Many enterprise/business applications I have seen could be web-based, but were not, because they needed access to various desktop APIs. I'll focus on three use cases here.
Authentication, Authorization, Audit
Web-browsers give no direct access to authorization, authentication and audit APIs provided by operating systems. Windows workstations are usually joined to an Active Directory domain. Permissions are managed by group membership within the domain. Hundreds, if not thousands, of groups and policies are serving usual enterprise. Restricted logon hours, whitelisted logon workstations, centralized collection of audit log. Every desktop application may call a few simple APIs to check if current user has specific privilege, is a member of some specific group, just lists all current user groups, or writes an important message to the event log. But good luck integrating this with your new fancy web-based SaaS. No single sign-on for you, no event log. If infrastructure is hybrid and the cloud part is Azure, you may have some luck with SAML and Azure Active Directory, but if not, you most likely will be asked to install on-premises version or leave immediately.
Printing and imaging
Web-browsers provide no usable printing APIs. Printing is important, whether it is cheque, report or handout. Most websites just give up on printing and export PDFs. This experience is terrible, starting with color support and ending with A4/Letter confusion. If printing is an essential part of your application’s workflow, like for a cash desk, web technologies are simply unusable. Google Cloud Print is discontinued, so the situation will become even worse. Scanning with preview? I don't even know where to start. It's simply impossible.
Industrial devices
There are a lot of industrial hardware devices. None of them can be accessed from the browser, if not explicitly supported, like FIDO tokens. Most can be accessed via text-based protocols over serial ports. They are begging to be wrapped into web-sockets.
Why is it so bad?
There are two answers I know: First answer is “other priorities”. Web technologies are mostly for landing pages, not for business applications, so a new CSS selector is more welcome than industrial devices. Second answer is “security”. It is hard to introduce new features without introducing new attack vectors.
The Proposed Solution
Create a universal windows service application which will provide a highly secure, easy to use REST interface. Allow JavaScript applications to fully integrate into desktop environments. Security is paramount. Permissions, which website has access to what APIs, should be opt-in only, clear, managed by Administrators only and optionally by global Active Directory policies. Everything is double checked, secured, isolated and sandboxed if possible.
The other side project keeping me busy has been setting up my desktop as a multiseat computer both at my desk and on the living room TV for my son to play some emulators, Minecraft, PBS Kids games, etc. As luck would have it, the length between the back of my PC and the HDMI input on my TV through the cable management arm, wall, closet, baseboards is juuust short enough that a 25ft regular passive HDMI cable will reach. I've got a Monoprice two port active USB extender hooked up as well going to a webcam mounted on top of the TV and a Bluetooth dongle that's mounted just barely peeking out from below. For a controller I picked up a bluetooth Xbox One controller and I'm using xpadneo as the driver for it on Arch Linux. That plus a Bluetooth keyboard and mouse are the only HIDs out in the livingroom and the keyboard and controller are rechargeable. It's better than any console and wound up being cheaper as well and it's expandable for e.g. one of our latest favorites of playing Hans Zimmer's "No Time For Caution" while playing SpaceX's ISS docking simulator with the goal of docking before the song ends.
That last side project has also expanded into some Minecraft modding working on porting an old mod that adds Joypad support to the PC version to more modern versions of Minecraft. Right now he's still pretty unfamiliar with using a keyboard and mouse so controller support is a must which really limits the mods available because that basically pins me to Minecraft 1.12.
- Setup my own personal webconferencing server (https://bigbluebutton.org/). I did this on Digital Ocean, which I'd never done before, but I couldn't provide the necessary bandwidth or hardware at home. It's really opened my eyes to having someone else host the infrastructure, but I still get the sysadmin control I crave, plus it's cheap and just so fast and easy to spin up new machines.
- I setup a phone number with SignalWire to hook it up to the webconference server as a dial in. That turned out difficult, so I quickly turned it around when it came up in my mountain rescue group that we had a need for a more customized replacement for GroupMe. I now have started working on an interactive system to manage callouts to missions.
- I went to setup a Gitlab server as a support tool for developing the aforementioned project (and other future projects), but it turned out to be quite resource intensive, so I learned to spawn it in Docker on my main development machine at home, along with a runner to do continuous integration.
- I finally got around to replacing my internal dhcp/dns/time/print/file server with something that uses an eighth of the power, produces much less heat, and is very quiet. It's so much nicer to have a quieter office.
- I've been working on updating my old library of code templates/snippets, including adding new programming languages. This project I also use to test out the Gitlab instance as my goal with the templates is to have things that are self-contained, but run a number of unit tests.
- I finally installed my smart thermostat, a HestiaPi (https://hestiapi.com/).
- I'm looking into RFID/NFC for a small project with my brother. He and I are also discussing a project using UE4. Hopefully I can find a way to cheaply host the Gitlab instance, or maybe I'll just end up paying for an account with them or Github, which I've also been learning how to do CI with and comparing with Gitlab.
- Since I'm also a member of a big band, I've been getting into home audio recording and mixing, using Ardour and Audacity (for click tracks). I'm hoping to get enough musicians on board so that we can make our own version of the Reddit Symphony Orchestra.
- So many other things! https://disaster.radio/, SDR, putting more holds on the climbing wall, trying new recipes, etc.
I've been keeping so busy I forget to eat (down about five pounds) and have been skipping exercise, but it's just so fun! I do wish I could muster the focus to work on something big, something worthy.
Despite having built this and painstakingly tuning a custom linux-rt system for optimal audio, building websites seemed to always escape me. I think quarantine has finally allowed me the time to understand the conventions of making static webpages for browsers.

Like the idea of monthly thread, let me see if i can add it on the site.
I've been working slowly towards a nebulous design I have for a quantum puzzle game, that maybe I can help myself and others develop the intuition needed in this budding field.
Nothing to show for it, but it's a long road I'm a few steps down, and I'm enjoying the scenery.
Unfortunately, it relies on their webhooks, which work only for Paid and Premium users
There is some decent information out there about it including open source solutions and many good papers (unfortunately some paywalled) and I've been working on a very primitive prototype, but I've been pretty distracted. I've also ordered some books on VLC, digital communications that cover theory as well as some more applied ones. I do hate how many of the books are either textbooks or associated with standards that seem to make them very expensive.
Unfortunately sooner or later, I'll have to face my extremely weak math ability, which I'm dreading.
Behind that I have a ton of side projects backlogged ranging from more digital communications and hardware stuff, to retrocomputing projects, to some ML stuff I want to try.
let me know if i missed anyone out.
