Finished Protogen Head
Adafruit makes a hat that you can plug right onto the GPIO port. I'm using rpi-rgb-led-matrix, I also have a guide you can watch on YT here https://www.youtube.com/watch?v=ssyTWpVEl0E

Please help. I just acquired this P10 led board and I want to be able to use it for myself but the WF2 card is locked. Is there a way I can reset it or use something else entirely?
Use a rgb matrix hat, a raspberry pi, and this library.

How can I play mp4 video using this Matrix LED Panel (video inside)
I found this https://github.com/hzeller/rpi-rgb-led-matrix, this provides python scripts. Please read through them, and then ask specific questions at each step. If python just looks like gobldegock, I suggest you go through some basic python tutorials docs.python.org has a tutorial page, and no you don't have to complete the whole think just read everything about built-ins and basic syntax (for, if, def, else, etc).

Ruby 3.3's YJIT: Faster While Using Less Memory
Obviously as an interpreted language, it's never going to be as fast as something like C, Rust, or Go. Traditionally the ruby maintainers have not designed or optimized for pure speed, but that is changing, and the language is definitely faster these days compared to a decade ago.
If you like the ruby syntax/language but want the speed of a compiled language, it's also worth checking out Crystal[^1]. It's mostly ruby-like in syntax, style, and developer ergonomics.[^2] Although it's an entirely different language. Also a tiny community.

What languages are useful for contribution to the GNOME project.
Crystal is a nice language that's not only simple to read and write but performs very well too. And the documentation is amazing as well.

Jets: The Ruby Serverless Framework
Ruby is a super fun scripting language. I much prefer it to python when I need something with a little more "ooomph" than bash. It's just...nice...to write in. Ruby performance has come a long way in the last decade as well. There's libraries for pretty much everything.
My modern programming toolkit is basically golang + ruby + bash and I am never left wanting.
I do find Crystal (https://crystal-lang.org/) really interesting and am hoping it has its own "ruby on rails" moment that helps the language reach a tipping point in popularity. All the beauty of ruby with all of the speed of Go (and then some, it often compares favorably to languages like rust in benchmarks).
