I never understand why people say things like this. It is not uncommon for languages to have multiple implementations, everything must not be abandoned for Rust man.

Mojo's origin can represent a lot of these semantics. I think a lot was learned from Nick's proposal, even if it wasn't directly implemented. Here is an example of how you could represent the first snippet, where two references can update the same list: https://godbolt.org/z/78bhzWjYM

Good. I too I'm not a fan of MCPs, but these days I do find them useful. In Claude Code I connected to my company's MCP which made Claude Code infinitely more useful for everyday work stuff

The pace the American government is willing to adopt new technology is underrated. Americans are very nimble

Yup. Go maturity is realising how little you need to use channels and Goroutines. You probably just need a setup in one place, like in front of incoming requests ... which using net/http already does for you.

Spamming them all over the place is a red flag imo

New comment by melodyogonna in "Platform-independent SIMD in Go"

Very neat, and comes pretty close to how Mojo handles portable SIMD.

It's great to see two of my favorite languages finally making SIMD easy to use. It's such low-hanging fruit for performance, yet somehow languages have ignored it for years. Portable SIMD, even with some performance penalty, still beats scalar computation whenever vector operations are needed. Yet language implementations always seemed to assume that hardware-specific SIMD APIs were the only way to go. That did nothing but make SIMD unusable excepting special cases where performance is absolutely critical, rather than just something anyone can use in day to day programming.

How so? I imagine you'd still want to constrain the length to the maximum vector size supported by the lowest platform you want to support or you lose the portability and actually end up with code that performs much worse than the scalar alternative on some platforms.

Mojo has an even more portable simd[1] type that isn't just generic over length but also over type. In my opinion it is almost always better to specialize for each platform and use portable implementation as fallback. It's a shame that just very few languages support Zig-like comptime, because it would be excellent for specializations without introducing runtime penalties.

Did you finish the video? It has CI, but I don't know if they implemented merge gating. Though I suppose that could be part of the land skill

I'm going to give this a try because I once also tried to make a slick GUI ide with Vim key bindings. Unfortunately I was trying to use Rust then, of which I had no experience, while trying to write a desktop app, of which I also had no experience.

The thing is, you can only program what is programmable. If a CPU has some capability that isn't programmable, I don't know what C or any other language is expected to do.
