Some tiny personal programs I've written
One fun one is I was playing a game with friends and it felt super random to me. So I wrote a simulator and some simple strategies to see how effective these strategies were vs randomness. If the game is mostly strategy you would expect to see clear difference in all of the strategies. If the game is mostly random the good strategies would have a hard time differentiating them from each other consistently.

Ask HN: What is the most impactful thing you've ever built?
Some things I built on the side, outside of my day job:
In the late 90's, I sold a command-line SMTP e-mailer for Windows. It was easy enough for folks to integrate e-mail transmission into their systems ... even 16-bit systems since spawning a copy of the shell would allow 16-bit systems to invoke my 32-bit mailer. Lots of folks had used these tools for all sorts of things. I got registration checks and cash from around the world before I started taking credit card payments.
I have an open source command-line MP3 player for Windows that folks still use and incorporate into their systems, JS libraries for node.js, ...etc.

Some tiny personal programs I've written
I wrote a command-line MP3 player in C for Windows. I just wanted to play with the media manger API's, but I've ended up using this to play MP3's in succession via a script.
https://github.com/jimlawless/cmdmp3
It doesn't work on all versions of Windows ... it depends on some configuration elements. This has been used in another developer's video game and I believe it's installed with an MP3 player library in node.js ( if you're running node.js under Windows. ) It also plays WAV files on Windows 10 (possibly 11) if you pass the name of a WAV file into the command-line.
I needed a command-line emailer that would send an email with a very simple one-line body for my Mac. I also wanted to exercise Go's SMTP libraries while experimenting with trying to build a minimal emailer application.

I use this regularly. I used to use it on MacOS, but I use it more frequently on Windows.
