With projects like these, I'm always torn between thinking that it's cool it's possible, and horror that someone somewhere will try to use this in production code.

The only one I really remember is Trogdor, but in order to keep it in my heart, I am a proud owner of Trogdor!!: The Boardgame

Depending on the complexity, there's also abbrev-mode: https://www.gnu.org/software/emacs/manual/html_node/emacs/Abbrevs.html

I started off this year with Go, and after the first three days, I was so happy to switch to Rust for today. It's one of my absolute favorite programming languages, but I never use it at work, so it's one of my joys of Advent of Code.

Thank you for sharing this. I also wrote a regular expression with \d|eno|owt and so on, and I was not so proud of myself :). Good to know I wasn't the only one :).

As a follow up, I've been playing with Elpaca, and they do indeed have a changelog. You can run elpaca-fetch-all and see all of the new commits for each package.

Thanks! I found the instructions here, which don't seem too hard: https://blog.voip.ms/voip-on-cell-phones-ios-and-android/

But otherwise, VoIP.ms looks pretty much like what I'm looking for. It also seems super super cheap for my needs (keep a phone number alive, make a few calls or SMSes per year).
