If you're into Rust, you'll know about the difference between Eq and PartialEq. Did you know that there's a secret third thing?

Mainmatter is looking for an experienced Rust developer to join one of our projects as a freelancer.

We're migrating a database from C to Rust. The project is complex and performance-sensitive. That's what makes it fun!

If you're interested, send an email to the address in the screenshot.

Congrats to @manishearth.bsky.social on unflagging TC39 Stage 3 Temporal in V8 today. Heading for Chrome 144 🎉

By many metrics this new date-time API is the single biggest change to JS ever 🔥

V8 uses Boa's temporal_rs by @jason-williams.co.uk Kevin Ness & Manish 👍

Had a nice day out at Slimbridge yesterday. Picked up the Temminck's stint bringing me to 196 UK species for the year. Also managed my first ever photo of a bittern!

Some bonus snipe showing very well, and a perfectly timed white fronted goose, first of the winter!

cant use x86 now that theres no second vendor anymore
people when it comes to Rust: "I won't use it because there's not multiple implementations"

people when it comes to coreutils in Rust: "How dare someone write a second implementation"
