The crates.io team was notified of two malicious crates (with similar names as legitimate crates) which were actively searching file contents for Etherum private keys, Solana private keys, and arbitrary byte arrays for exfiltration.

Happy 10 year anniversary to this tweet! Has memory safety in C++ been solved yet?

A tweet from @CppCon from 22 september 2015: "Herb Sutter says we are close to solving memory safety in C++ without runtime overhead. #CppCon"

Found what appears to be my oldest game save on a physical memory card. From about 18 years ago!

This is from The Simpsons: Hit and Run. On a GameCube memory card.

I do probably have some N64 memory cards lying around... Hmmm.

Yeah I am annoyed by that. I had to click to see the full address.

FYI, I got an obvious phishing attempt in my inbox from `[email protected]` that was masquerading as a security breach notification. It made it past gmail's spam filters.

The link goes to the `github.rustfoundation.dev` domain.

I would definitely question the 99% number there. And yeah, people will disagree about whether a loud failure is better or worse than a silent logic failure in any given scenario.

Andrew Gallant @burntsushi.net · 28d

Yeah you certainly aren't the only one to hit it. It's a tough problem. Like, I could just make it so you can't do arithmetic on a `Timestamp` with a `Span`, but that also feels like a bit of a bummer.

Andrew Gallant @burntsushi.net · 28d

What did it stop you from doing?

Andrew Gallant @burntsushi.net · 28d

Right, in this case, Jiff is preventing you from doing calendar arithmetic on a type that cannot support. Because the only way to do calendar arithmetic correctly is with a time zone.

Andrew Gallant @burntsushi.net · 28d

Jiff is *heavily* inspired by Temporal.

Today, we're announcing our first hosted infrastructure product: pyx, a Python-native package registry.

We think of pyx as an optimized backend for uv: it’s a package registry, but it also solves problems that go beyond the scope of a traditional "package registry".

You can do `echo '!/.github/' >> .rgignore` in your repo root and that will forcefully whitelist the directory.

Here are a few more.

He was a great cat. I'd always tell the vet (on his many, many, many visits over the years) that while he was a squirmer, he didn't have a mean claw in his paws.

Plato, Aug 2010 - July 7, 2025. You never did quite learn how to poop like a normal cat, but I loved you anyway. I'll miss you buddy.

Feel free to open a question if you want more help.

Andrew Gallant @burntsushi.net · Jul 4

Yes. You can do that. You can literally match arbitrary bytes. There are examples right in the `bytes` module: docs.rs/regex/latest...

regex::bytes - Rust

Search for regex matches in `&[u8]` haystacks.

Andrew Gallant @burntsushi.net · Jul 4

The regex crate can already match non-UTF-8 patterns.

bsky isn't really the best place to ask technical questions like this. Can you open a question on the regex repo instead? github.com/rust-lang/re...

Please include more details. Like an example of what you want to work but doesn't today.

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.

The uv build backend is now stable, and considered ready for production use.

An alternative to setuptools, hatchling, etc. for pure Python projects, with a focus on good defaults, user-friendly error messages, and performance.

When used with uv, it's 10-35x faster.

"Jiff's main datetime type, integrates the timezone without a generic. This lets us get rid of DatePatternContext entirely, replacing it with just a Zoned to represent the current time."

Vindication!!! Haha

spent some time switching #jj-vcs over to @burntsushi.net’s Jiff for datetime handling. look at how much simpler (most) of the code is! github.com/jj-vcs/jj/pu...

there are some things i want to improve down the line, like adding reference support to interim so we can pass around an &Zoned, but…

It wouldn't be intended for others to use. It will just be for my own personal use. (Kinda like my dotfiles repo. It's open source, but totally bespoke.)

Andrew Gallant @burntsushi.net · May 18

The only thing I'll be switching to is my own SSG. I've learned my lesson.

Thank you!
