I haven't used Perl since writing CGI in the 90s, and I'm not a fan of the syntax among other things.
But I'm great with regular expressions. It seems like everyone around me swears regexes are an impossible black magic, and so they think that I'm some epic level wizard. And I have Perl to thank for that.
I've seen a number of "build an OS" tutorials pop up recently, and that's awesome! Building an OS will definitely help you understand how to write better user-space programs, and it's fun.
One thing I wish is that more of them would feature UEFI instead of BIOS, or at least come with a warning, as Intel plans to drop support for legacy BIOS in 2020.
Going through UEFI is actually easier anyway, IMHO. ... Maybe I should stop complaining and write that tutorial myself instead. Hmm.
I applaud your goals with your community, and wish more game developers and game-adjacent companies would think similarly. I've worked on games that didn't care, or didn't put the effort in, and so ended up with fairly toxic communities. When I was at Runic Games, I was amazed to see how inclusive and positive a gaming community around the Torchlight series was, but it definitely took work from the very beginning to make it that way.
The interesting thing here would be seeing some form of aggregation of various projects to see what effects the language does have on style. Would love to see something that shows the effect of e.g. Python's whitespace or Go's boilerplate.
