Linux

NOTE: Although I rarely use Linux for any of my personal projects I will list it here. Linux is where I got my start on this UNIX journey back in the 1990s while working for VA Linux Systems. Linux has changed alot since then and in my opinion it has strayed far from the UNIX philosophy. That said, I like to keep a “best tool for the job” approach to operating systems.

systemd

I am not a fan of systemd.

Linux has some slop
