Ask HN: Tools you have made for yourself?

Not my tools, but been following 100r long enough to know why they build their own tools: https://100r.co/site/home.html

A friend and I always develop small scripts to generate stuff that's really boilerplatey in Android, basically writing text to files with node.

I've also made my own autoclicker for grindy Android games that otherwise detect in-OS clickers by basically using batch and adb to click certain spots randomly in a while loop.

Also a few batch scripts for a musician friend who's 0% technical to separate mp3 songs into instrument tracks (to rehearse and have fun) with spleeter by just dragging the file into the .bat.

Oh and a bunch of mini scripts to pull and merge stuff from one git branch to another and push it all (like dev to staging) to trigger a CI flow.

I have never contributed much to open source, but my high water mark was writing reportdhcp, the first available tool to report the status of DHCP pools. I wrote it because I needed it and none existed that I could find anywhere. It got packed into a few distros. After only a few years it was replaced by better tools (and in fact, I was even proud of the fact that the author of one specifically called out that it was better than reportdhcp). Got written up in Linux Magazine and one other publication at the time. I'm no superstar like many of you luminaries, and in fact I wrote it with the Llama Book sitting in my lap, but it was great to contribute the open source ecosystem to which I owe a large chunk of my career.
