Congratulations!
I also created a little AUR package or two or manually fixed some broken PKGBUILDs sporadically, and yeah it’s something you can figure out in a day when you have a little bit of understanding of the command line overall.
Arch AUR is really a nice sweet spot between power and convenience.
My boss at work is using Gentoo. I guess that’s why he’s my boss. No, but seriously, the Gentoo build system sounds much more complex. Yes, you can control compilation flags and tweak every package up to absurd details, but I’m willing to sacrifice the few percent of performance.
Whereas, AUR is simple enough to be used by ADHD folks like us :D If it’s more work than a weekend project, I don’t care about it. I know I will most likely give up on it if I don’t need it to survive.
In the old days, a few motivated nerds could write a browser. Now all you can realistically do is take a browser engine and build some user interface around it. That what most “alternative browsers” do - tweaking or repackaging.
These days, a browser is like it’s own operating system with sandboxing, various Interfaces to periphery devices, hardware acceleration for GPU and all the bells and whistles taken for granted now.
I’d say that imagining it to be on a scale similar to working on the Linux Kernel is more right than wrong.
So we definitely very much want Firefox to survive, or it will be much worse than the Linux/Mac/Windows trilemma. Microsoft Edge is chromium under the hood too. Any many desktop “apps”.
