> Could they not have upstreamed those features in the first place?

Often when you are working on a downstream code base either you are inheriting the laziness of non-upstreaming of others or you are dealing with an upstream code base that’s really opinionated and doesn’t want many of your teams patches. It can vary, and I definitely empathize.

This looks good

With any luck, this new computer can usher in an era of folks not having to port anything to windows.

It's almost as if they weren't lying when they said dropping it in the phone was a waterproofing measure. I guess people aren't dropping their laptops in pools all the time.

This guy gets it. Yes bingo. It's the VFS' filters/ACLs support afaik.

WSL is the best way to avoid all the Windows slowness as far as the VFS and the forking overhead.

This shouldn't be surprising. macOS has a faster filesystem+VFS than Windows, and the single thread perf of the M4 beats most PC cpus. I'm not sure what linker rust uses, but the apple native ld64/ldPrime is also pretty fast as far as linkers go.

Windows is also slow enough at forking, that clang has "in-process CC1" mode because of it.

I guess PCs and chromebooks are over? Literally what normie would pay more for a worse experience now?
