And behind on a lot of stuff. The Microsoft's ACLs are nothing short of one of the best designed permission systems there are. On the surface, they are as simple as Linux UOG/rwx stuff if you want it to be, but you can really, REALLY dive into the technology and apply super specific permissions.

Oh yeah for sure. Linux is amazing in a computer science sense, but it still can't beat Windows' vertically integrated registry/GPO based permissions system. Group/Local Policy especially, since it's effectively a zero coding required system. Ubuntu just recently got a way to automate its installer (recently being during covid). I think you can do the same on RHEL too. But that's largely it on Linux right now. If you…

Valve is practically singlehandedly dragging the Linux ecosystem forward in areas that nobody else wanted to touch. They needed Windows games to run on Linux so we got massive Proton/Wine advancements. They needed better display output for the deck and we got HDR and VRR support in wayland. They also needed smoother frame pacing and we got a scheduler that Zuck is now using to run data centers. Its funny to think tha…

Valve... please do Github Actions next

This isn’t explicitly called out in any of the other comments in my opinion so I’ll state this. Valve as a company is incredibly focused internally on its business. Its business is games, game hardware, and game delivery. For anything outside of that purview instead of trying to build a huge internal team they contract out. I’m genuinely curious why other companies don’t do this style more often because it seems incr…

I feel like I rarely see contacting out work go well. This seems like an exception
