>The rust code was running circles around their Swift ones even when we tried to keep implementations the same.

I've done Advent of Code a few years -- even Javascript implementations, if using a good (optimal) algorithm, are highly performant, so I'm suspicious of the claim. In most AoC problems, if your code is observably different between languages, it's the fault of the algorithm, regardless of language. But perhaps you are referring to well-profiled differences, even if there are no observable differences.

That said, in projects other than AoC I've compared Swift to C++ and it's hard to deny that a low-level language is faster than Swift, but Swift itself is certainly fast compared to most dynamically typed or interpreted languages like Python, JS, Ruby, etc. which are vastly slower than anything in Swift.

For what it’s worth, the same is true of Swift. But since much of the original Rust team was also involved with Swift language development, I guess it’s not too much of a surprise. The “unsafe” api requires some deliberate effort to use, no accidents are possible there. It’s all very verbose through a very narrow window of opportunity if you do anything unsafe.

Apple has pushed OS updates to help the Asahi team, though they did not publicize this, of course.

I used an iPhone 4s from 2011 until end of 2018. Probably most remarkably, I never put a case or any kind of screen protector on it. The thing was still practically scratch free when I stopped using it. It’s still sitting in a drawer next to me.

Heroku is mentioned in the first sentence.

And much of Europe.

As do many other countries. You really cannot live without it in much of the world.

They are typically referred to as Porter Duff blend modes, so I assume that these algorithms were invented mainly by those guys. (by Thomas Porter and Tom Duff)
