Apple supported OpenGL plenty, just that the world moved. Apple created metal, shortly after Vulkan was created.

"They could support it if they wanted to" is almost a tautology. Of course they could. But then they have to support another thing. They are on the hook when something goes wrong.

Also looking at block-based content store so that blocks can be deduped across images.

Old docker discarded the compressed bits but kept some metadata about the the so it can at least recreate the tar.

It also recreated the manifest o push.

Buildkit isn't changing behavior here. Internally in docker there is a shim to make the legacy storage behave like containerd snapshotters (as well as it can, anyway--not perfect due to hard to resolve issues in the old storage). But it still kept both the compressed and uncompressed versions of images.

The problem isn't that kids can't learn on tech, it's that the whole thing was done in the worst way possible.

Its a Buildkit frontend, so you still use "docker build".

Nix isn't some magical thing that makes things reproducible either. nix is simply pinning build inputs and relying on caches. nixpkgs is entirely git based so you end up pinning the entire package tree.

Tokens are expensive. We don't know what the actual cost is yet. We have startups, who aren't turning a profit, buying up all the capacity of the supply chain. There are so many impacts here that we don't have the data on.
