An alphabetical list of software that I really like.
Apache: Not as popular as it used to be, but I know it and so still use it
Audacity: Or is that too controversial now with their telemetry?
bash: The best interface to my computers
Civilization IV: Yes 4, the only software that is not (yet?) open source
cron: It wakes me up every day (using mpv and bash)
Debian: I run it on almost everything
ffmpeg: to convert video formats
find: because I tend to forget where I put stuff :)
Firefox: because an alternative browser is crucial
FreeCAD: Amazing CAD software, and I like math
gcc: Because coding in C is fun!
gimp: Easy image manipulation
git: How did I ever live without it?
gramps: To keep track of my ancestors
grep: Often very useful.
Homebrew: To make a MacBook usable
Inkscape: Because vector graphics are essential
make: For software that is not part of Debian
mariadb(mysql): So easy to build a database
PrusaSlicer: A 3D printer opens a whole new world of possibilities
Python: I hate this language, but it is used so much and coding is still fun
return Youtube dislike: How else is Youtube usable?!
rsync: For backups
Singlefile: because web pages tend to disappear forever
ssh: Multitool for anything remote
Thunderbird: Reading my mail since 1996 (as Netscape Mail)
Video downloadhelper: because video's tend to disappear forever
vim: By far the best editor for text, code, config files and more.
wine: To play that one game on Debian (though I wish its 32-bit had as much memory as 32-bit Windows XP)
Wireshark: The best tool to learn about networking
XFCE: My GUI since almost 20 years
xfce-screenshooter: Because screenshots are useful
