A pineapple de-corer and slicer. An $8 tool significantly improves the ease and efficiency of getting maximum pineapple value.

There is nice tool called `aha` that converts ANSI color codes to HTML colors. See https://github.com/theZiz/aha Example usage: pipe to it any command with color output then send result to an .html file:

   git diff --color | aha > ~/Deskop/changes.html

Very useful in combination with the `--color-words` option for git diff, which highlits only specific words that were changed, which is great when reviewing changes to text files (e.g. blog post written as .md).

I wrote a small utility named "reminder" that lets me set a reminder, optionally with a message, for any time in the future. When the time comes, I get a phone call (and an SMS if I attached a message).

PureText. Windows tray utility that removes all text formatting from whatever is in the clipboard.

If I spend money on software, that means they are worth paying for over the free options!

- WizTree: https://diskanalyzer.com/

- WizFile (can search Google Drive!): https://antibody-software.com/wizfile/

- Fork: https://git-fork.com/

- Directory Opus: https://www.gpsoft.com.au/

From the top of my mind (both are free for personal use, AFAIK):

- BRU[0]. I have to batch rename dozens of files very often and this works like a charm. Some people will say the UX is clunky but I think it's awesome![1]

- PDFill[2]. Simple PDF tools that work.

Not necessarily tiny, but awesome single-purpose gardening tool for removing weeds without overworking your back.


👤 jshawl
minisign - https://jedisct1.github.io/minisign/ super simple digital signatures!

I have my own ARM reverse engineering tool made with unicorn, capstone, and keystone. https://s1.danielc.dev/re/ and https://s1.danielc.dev/re64 I use it pretty much every day.

Sensepeek PCBite probes[1]. Hands-free connections for multimeter, logic analyzer, or oscilloscope makes checking signals in circuits easy. Even with some very small SMD parts.

Recently bought a Time Timer.

Great little timer and since I run my life by timers/time blocking things I find it really useful, just to set a timer and go and I can easily see it visually which helps keep me focus. Completely analogue so no reaching for my phone.

Monitor Control for MacOS. It lets you control the brightness and volume of external displays. It looks and feels like a native feature.

SelfControl for MacOS reliably blocks websites for a custom amount of time.

Shazam for finding music you hear. It still feels like magic.


👤 gnatman
SelfControl for MacOS - let's you set a domain blocklist and a time limit. It's pretty tamper proof too, surviving reboots, etc. Really helps me buckle down when I'm resistant to getting work done!

👤 yareyaredawa
Definitely HandBrake, being able to quickly compress a video is so clutch

👤 cloudking
Ffmpeg

👤 mikewarot
I really like time.gov, if you need to know (within a second or so) what time it is, in the US... they've got you covered.

👤 piezoelectric
Pacstrap, as it saves you so much time during the arch installation, especially when installing the base and kernel

👤 sableye
I'd be lost if it weren't for `tldr` on my terminal. Also KeePassXC, what a life-changer digital safe.

👤 jareklupinski
i installed a "shell gpt" that lets me do things like:

    sgpt "please show me a javascript function that appends to a list if the arguments are within seventeen days of each other disregarding timezones"

👤 rossant
Dynalist. For todo lists, notes, prose, everything really.

👤 trent1971
Mouse jiggle, for keeping my computer from going to sleep.

Git, it's saves you so much time
