so.... now that most of the UCG is archived and only the glossary remains, maybe it should be folded into the Rust reference? rust-lang.github.io/unsafe-code-...

today in "why computers why", Apple's Translate app turns "Jajniki" (Polish) into "Overies" (US English), instead of "Ovaries". I've looked everywhere and can't find traces of that spelling online. Trying to translate back yields nothing since, well, it's not a word.

Hey man I have one quick question: what the fuck andre.arko.net/2025/09/23/a...

is rustc doing LTO for libstd even with -Clto=off?

I hope the ladybird devs knew they were going to be put next to hyprland feat. dhh shit (cf. drewdevault.com/2023/09/17/H...) blog.cloudflare.com/supporting-t...

oooh the compiler explorer "Claude Explain" thingy is powered by 3.5 Haiku, I wish I could plug in my API key instead and use Sonnet 4 at least

does passing -Cllvm-args="-ffast-math" to rustc do anything or is it overriden later on?

is there any way to safely transmute from (T, T) to [T; 2]? I know (T, T) is repr(Rust) and there are no guarantees as to what the layout will be but... can we tell rustc "try your best, if you don't succeed panic"?

oligamiq.github.io/rubrc/ doesn't work for me :( what am I doing wrong?

Oh, more .cargo/config.toml cursed-ness? Due to an unfortunate interaction between toml and targets with "."s in their names, like "thumbv8m.main-none-eabi", it's not *entirely* clear how you SHOULD set certain configs in your .cargo/config.toml: github.com/rust-lang/ca...

Hey, #ruby folks! I've been one of the #RubyGems maintainers for the last decade. Ruby Central has forcefully taken control of the RubyGems organization on GitHub, the `rubygems-update` and `bundler` gems on rubygems[.]org, and more. You can read the details here: pup-e.com/goodbye-ruby...

I thought the rust coreutils cksum fix would be interesting but it's literally just "use a crate that does SIMD"

proposal: make the lifetime single-quote marker in Rust a combining acute accent before: 'arr, 'num, 'obj (boring, americano-centred) after: árr, ñum, öbj (delightful, festive, welcoming)

Gregory Terzian is talking about how to embed @servo.org at GOSIM Hangzhou

Reminds me of PackagingCon, a conference about software package registries, being easily confused with Packaging Conference, a conference about packaging physical goods.

a friend and I were wondering: is there a locktoberfest? and the answer is: yes, several, but it's... not what you'd think www.discoverlockport.com/locktoberfest

Uhoh, we broke Zed's auto-updater. 🫣 If you're on v0.203.x or v0.204.x, you'll need to manually check for updates via the Command Palette→ "auto update: check" We've already shipped the fix - just need you to unbox the latest, shiniest version of Zed manually this time.

PSA: don't fall for the crates.io phishing campaign: fasterthanli.me/articles/cra... #rustlang

Someone is trying to pull off a supply chain attack similar to npm’s but on crates.io: github.com/rust-lang/cr...

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.

How much do you think Expensify paid to be a sponsor in F1: The movie? use.expensify.com/blog/expensi...

A friend has noticed that AI agents don’t like the word “chonky.” Several times now they’ve tried to remove it from the code unprompted, both during code review and locally.

this is getting ridiculous

While it could still be better, renewables have been booming in the past 10 years. Solar itself has grown ~1000% in that time period, and battery tech is evolving rapidly in all the good ways. Even with recent setbacks with federal stuff, we hit a HUGE milestone this year!

has anyone made a cooking show called “don’t fry this at home” yet

uhhhh

I'm cleaning up a lot of LLM-assisted code I wrote a while back when I was badly burnt out and I'm having fun going on the hunt for dead code / seeing how much I can simplify things. Driving up code coverage + commenting out things, if no tests fail, we're good!

Well I'll be damned. I might have to switch phones after all even if all the new ones are oversized. Unfortunate this looks opt-in for third-party apps. I wonder how much adoption there will be. Hopefully WhatsApp and Signal will adopt it right away?

currently fighting with crates.io/crates/jiff which is probably trying to stop me from doing something silly

👋 Any books y’all would recommend re: Bipolar Disorder?

I have just compiled Rust code for bare-metal SPARCV8 and executed it under Solaris 2.6 on a microSPARC-II. I suspect that no-one has ever done this before. Literally no-one.
