I'm a member of Futurewei's Rust team, and I'm in the Compiler Contributors group. I started these posts back in 2016 when I wasn't a member of either. It's been a long-running series, and there's never been mu

I just want to say that this is a very weird but cool approach that I never would have thought of. Nice work!

No problem, I learned that I shouldn't post drafts and assume they will go unnoticed :)

The book is primarily about Rust-specific things. Section 1 says: "Some of the techniques within are entirely Rust-specific, and some involve ideas that can be applied (often with modifications) to programs written in other languages.&

It was a really weird and messy situation, and unpleasant to live through. I agree that Brendan's Prop 8 donation was bad. But he did it privately, and never (AFAIK) made anti-LGBT comments in public. People who had worked with him for

I think there is confusion here over the meaning of "Rust developer". Mozilla did lay off most of its employees that were working directly on the Rust language and its implementation. This was a handful of people. Mozilla also lai

I mentioned in the post several areas I myself haven't looked at, including cache misses. There may be room for improvements there. There is an experimental parallel rustc front-end, e.g. see https://internals.rust-lang.org&

Thank you for the kind words. To clarify: I am still at Mozilla! But I will be working fully on Firefox for the foreseeable future. I have edited the opening paragraph of the post to make this clearer.

Coming up with a binary "is this acceptable?" heuristic is also harder for performance than it is for correctness.

Yes. The good thing about this metric is that there is very little variation, unlike wall times, which makes it easier to spot regressions.

Hi, I'm the author of the blog post. There is definitely a marketing angle to these posts. Rust has a reputation for slow compilation, and one of my goals is to show that (a) people working on Rust care about compile times, and (b) imp

That's an excellent explanation. A small correction: if I recall correctly, the Corporation is legally allowed to give some money to the Foundation, and it does so. But the allowed amount is quite small -- maybe a couple a million a ye
