My daily driver machine is refurbished Thinkpad x260 running Manjaro (with sway). Raspberry Pies are also great tools that I hold very dear (in fact, this website is powered by one!) and I would wholeheartedly recommend getting one if there's interest in GNU/Linux, running a server, etc.

Since I spend a lot of time in the terminal (kitty!), I'll mostly use (neo)vim. It has been my preferential code editor for many years, even after VSCode came along with LSP functionalities, etc., and it made me appreciate economy of resources, elegancy in commands, and accessibility in general.

For mathematics, I cannot stress the greatness of SageMath.

mpd is a very complete tool for what I need in terms of music. For a front-end, I'll have ncmpcpp.

ffmpeg is an incredible tool for everything related to video manipulation, and VLC is very reliable at reproducing anything I throw at it I am transitioning to mpv.

I, uhh, I tend to hoard programming tutorials and resources that are somehow recommended or endorsed by Hacker News communities at large; and of course I will never go through all of it, but in case it is useful for anyone, behold my programming resources dump 📦.
