THIS IS NOT A DRILL

i take great solace in the fact that my brother, the only true 10x software engineer that i know, has barely heard of IDEs let alone "generative AI"

all these people go on about how stable C and C++ are, and how Rust changes too much.... but then they also talk about how their work codebase is stuck on C89 or C++17.

who do i have to pay to get a rustfmt that doesn't shit itself on long lines

Once I wrap up some other projects. It is definitely on my list.

Useful not just for language keywords, but also identifiers given meaning by macros. For example `thiserror` treats fields named "source" as the Error::source() of your error. If your source means something else, instead of fussing with some kind of #[not_source] attribute, just name it r#source.

once again, #rustlang is the most admired programming language on the stack overflow survey: survey.stackoverflow.co/2025/technol...

Howdy all. I'm unfortunately not going to be with my employer for much longer due to team relocation. If anyone has any info on roles that would allow me to continue my Rust compiler work (in New York City), they'd be greatly appreciated.

Today, we’re announcing the preview release of ty, an extremely fast type checker and language server for Python, written in Rust.

In early testing, it's 10x, 50x, even 100x faster than existing type checkers. (We've seen >600x speed-ups over Mypy in some real-world projects.)

There are probably 4–6 people who, if they had dedicated their 10 years to a different language or hobby, you would not be hearing success stories about Rust.

but what I can say is, I personally sat down one evening and said "I think Rust can be the next great systems programming language" and then dedicated the next ~10 years of my life to making that happen

very glad to see this rust-for-linux.com/rust-kernel-...

We’re building a new static type checker for Python, from scratch, in Rust.

From a technical perspective, it’s probably our most ambitious project yet. We’re about 800 PRs deep!

YouTube video by Oxide Computer Company Oxide and Friends 1/13/2025 -- Crates We Love

Not a surprise that we love Rust at @oxide.computer! It's ecosystem of crates is a great strength. Last night @bcantrill.bsky.social and I spoke with our colleague @sunshowers.io, @elizas.website, and @steveklabnik.com about the crates we love. Lotta great stuff out there!

The Rust ecosystem is amazing, but it can be hard to discover new crates. Today @ahl.bsky.social and I will be joined by our colleagues @elizas.website and @sunshowers.io, who will offer their wisdom and walk us through some crates you should know. Join us, 5p Pacific!

This is the ideal design for a trait-impl-based serialization library IMO. See this comment: github.com/serde-rs/ser... where I arrived at this same concept (in less detail) where it talks about "the ultimate non-generic DeserializeSeed" as my preferred design for a standard library std::serde.

I hope you all enjoy it, I enjoy these weird corners of language design.
