Here's a neat little article I've had bookmarked for some time now about why Perl fell out of use, from the perspective of someone who was around during its surge in popularity for webdev back in the late 90s/early 00s. Definitely illuminating imo as someone who only picked Perl up for the first time in the mid-late 2010s
Fedora! Have been super not a fan of Windows for years now so I avoid it hardcore when I can.
Linux in general is a lot easier to set up programming environments on, and also just generally it's a lot more flexible when it comes to customization, which is definitely important when you're a big picky bitchbaby like I am.
Fedora specifically I like because there's something I just really like about RHEL-related distros (to the point that i use Rocky Linux on my server also). They feel really polished and dnf is probably my favourite package manager of all the ones I've tried so far. I do have a few issues with it, and I miss having access to the AUR when I used various Arch-baseds over the years, but all in all I'm very happy with it and I don't see myself switching distros for desktop use any time soon.
