What are you working on and why is it cool?

I am planning out (nothing to show publicly yet) an automated dynamic algorithm configuration framework for solvers of difficult optimization problems. It is cool because there is a bunch of techniques from all over different kinda isolated areas of academia which became more accessible to hobbyist due to the covid era. There is also a lot of beauty in some results i plan to use. https://www.researchgate.net/publication/3516098_Optimal_spe... .

I am also working on letting computers search algorithms that lets one multiply square matrices asymptotically quicker. Whether i will find any method that will yield any improvement over the state of the art i do not know yet. But it is cool because it is kinda like a puzzle where i can let computers chew on it for a while before come back to it later and have a look whether i see a way to improve the process. If someone has a lot of surplus compute renewable powered i could use occasionally i wouldn't mind such an offer. The problem is really embarrassingly parallel and probably also resumeable in case of power off.

It is at present just at conceptual level, but I am talking to the stakeholders.

Why is this cool? Well, if this works, then not only will it make education easily accessible to everyone but it will also fundamentally change how education benefits society.

Feedback and collaborators welcome :)

Going to plug it and consider this my weekly marketing complete so that I can justify going back to coding.

I'm building https://feetr.io which is a stock discovery algorithm and it's cool because it found two stocks yesterday: AMC and BBBY. AMC went up 34% and BBBY went up 24%.

What makes it cooler, I think, is that it is averaging 4.2% daily increase across all stocks, with the best performing of each day averaging 6%.

What might make it cool for the HN crowd is that every single part of it is written in common lisp. I got a lot of "are you sure" at the beginning because there is this entrenched idea that lisp can't be used for serious work. Happy to report that that view is completely wrong in my case.

I get so excited to build each individual component and so I don't suffer from the burn out or flailing interest that seems to plague a lot of other indie hackers.

Feetr will be a paid service when it launches but I think very justifiable at $8.99 per month. As it hasn't launched, I'm spending time talking through the stocks that it's watching during premarket trading, hoping to show people how it works, what it's looking for and potentially what to expect for the coming day.

Matano - (https://github.com/matanolabs/matano), an open source security lake platform on AWS. Let's you run security log analytics on an open data lake, and detections as code in your AWS account.

Cool because it's all OSS, serverless, high scale, low cost, and built with modern technologies like Rust and Apache Iceberg.

An alternative Microsoft Teams client. It's cool because it doesn't warm your computer as the official client does. (https://www.opercom.co.uk/) the website needs a complete revamping and the UI is being changed to be more modern.

I'm working on https://liminal.market

It brings the stock market to the blockchain. Like money (USDC, USDT) you bring into the blockchain it needs to be represented by some token, so when you buy stock you get token(AAPL token when buying Apple) with the shares you bought. You own the shares, get dividends and voting rights.

First version is only buy and sell, next is to allow services to use the smart contract, allowing defi services to provide not only crypto tokens on their exchanges but also stocks.

There are currently over 5.600 different companies available for purchase

https://sumi.news – it’s cool because it’s made for skimming, not doom-scrolling. It’s only headlines grouped by day and source.

no website yet, but my project lets you:

- select a data source (e.g. csv file or remote database)

- select a data transform function

- select a data sink (e.csv or remote database)

- execute that pipeline

all of the ui within the browser, would it interest anyone? im curious.

https://github.com/hofstadter-io/hof - data modeling & code gen tool, open-source and open-ecosystem. The goal is to code gen the majority (80%) of the mundane code so we only have to work on the interesting parts. You can use any language or technology.
