QGIS and OpenStreetMap for mapping

OpenSCAD and Gitlab. I can quickly iterate on designs through code, push it to my Gitlab instance, and have my CI/CD pipelines pick it up, render it, and automatically slice it in some common profiles to send to Octoprint

For games:

• Anuto TD (found a few days ago, isn't super feature rich but still fun to kill time)

• Mindustry (never played a game like it before, ended up supporting by buying it on Steam)

• Supertuxkart (I love how many custom add-on karts and tracks I have)

For non-games:

• Termux (allows me to get apk files and install Revancify for add free yt)

• VLC (I don't mind slow updates and have yet to switch mostly because I can't find anything better that isn't more complicated than it needs to be and/or is closed source)

• KDE Connect (I have almost always had problems with moving files from and to my desktop via cord)

I'd include something like Linux, but I personally feel that's kinda cheating because of how large it is compared to the others.

Neovim. It's an awesome editor and it has a great community and ecosystem.

Linux, of course. But another one that I use all the time, and love to death, is SageMath. It's the perfect blend of mathematics and programming for me.

Hard to answer but maybe Haiku or GNU Emacs

Currently OBS and Motrix

vim

Definitely OpenFOAM. It competes with commercial software that costs thousands of dollars.
