We also found that if Xinjiang were a country, it would have the highest incarceration rate in the world at 1,944 per 100,000 people. China has an incarceration rate of 119 per 100,000 people.

Woo! `assert_matches` is finally stable!

I worked with the LangChain folk on SmithDB earlier this year. It was a great challenge, fun work, and a good example of using async Rust + Vortex/Datafusion + Cloud storage to make a high performance, domain-specific distributed DB. www.langchain.com/blog/introdu...

So, lucky people who were at Rust Week, what were your highlights that I should watch? (Don't say 'getting to hang out with a bunch of cool people in a cool place', because I feel bad enough about not going already)

Parents who refuse to ever choose for their own child to have less are a major contributor to the suffering of children in the world. After working in education I've seen hundreds of parents who claim all the right values right up until their own kid might lose a tiny sliver of anything at all

Tightly coupled to this hot take is a second one, we mythologize parenting and parents to a degree that also stifles societal progress and harms children greatly.

I don’t mask as much as I did for a long time, but still do anywhere I think is high risk, and I get like half the number of colds, even with little kids. Well worth it

Worst five minutes followed by best five years of my life. Highly recommend and surprisingly cheap.

I hate to boost Amazon, but I bought this little tool set for electronics, etc. a few years back and it is probably the best $13 I've spent. I use it every day: www.amazon.com/AmazonBasics...

Edited and improved the interop chapter of my error handling guide: nrc.github.io/error-docs/r...

I've been looking again at my old #RustLang error handling docs. I've edited and improved the Result (nrc.github.io/error-docs/r...) and panicking (nrc.github.io/error-docs/r...) chapters. More updates coming soon (the rest still needs work).

It took me 12 attempts, but I managed to deploy an mdbook to GitHub pages. I'm a professional!

OK, so here's a few words about different kinds of timers, why SYSTICK is good for what it was designed to do and crap for the modern tickless world, and how I implemented embassy-time for the Armv7 Generic Timer. thejpster.org.uk/blog/blog-20...

The head of the OECD’s New Zealand desk has bluntly told an audience at the Commerce Commission’s Competition Matters conference that the keys to turning around the country’s economy lie in reducing bank profits and fixing power market.

Today is the 11th birthday of Rust 1.0! 🥳 🎂 🦀

New Database product based on Apache DataFusion from @langchain.bsky.social -- focused on agent observability. It is really neat to see how people are building (very) customized data + query systems faster than ever now that they don't have to build the whole stack www.langchain.com/blog/introdu...

If you're an Apple user, it seems like today's iOS and MacOS updates are ones you'd want to install sooner rather than later (because of the security updates rather than the new emojis)

I love to help people learn #RustLang and get better at Rust programming! I have well over a decade of experience with Rust (including extensive work on Rust from before 1.0, core team membership, and other leadership work), and have helped numerous people learn it and teams successfully adopt it.

I can too, the answer is: YES! (kidding). Nicholas is great, so reach out to him if you need help with Rust.

🎉🎉 I've been working with the folk at Tailscale on their new #rust-lang library. Last week it was officially announced (tailscale.com/blog/tailsca...) along with open-sourcing the code (github.com/tailscale/ta...).

The Spinoff is appealing for new members. I think it's the best news source in AoNZ and are well-worth supporting (I'm a member). If you can, please support them too: thespinoff.co.nz/society/12-0...

Rust Analyzer seems to be struggling with a lot more false positive errors than usual. Has something changed recently? Or is it just having a temporary bad time?

Couple of people come into the cafe, one has a smoothie. “Really sorry, you can’t have outside drinks in here”. Sad face. … “here” gives her a takeaway cup to hide the smoothie in. Some people are cool!

ANOTHER vuln?! What is going on these past few days?

IDF soldier who participated in the mistaken killing of three Israeli hostages in Gaza City in Dec 2023 confirmed to his mother what was widely reported at the time: they killed the men, who were waving white flags, because their unit was under orders to kill all Gazan men they encountered.

Some thoughts on AI (I'm resisting writing a blog post because I have nothing of great value tbh, but it is a hard force to resist): I understand a bit better people who say it's fun to use. It kind of is if you have something you want to build and if there is a lot of boring code to get there.

`pub(...)` was a mistake: `pub` should mean `pub(crate)` and there should be `export` or similar to mean current `pub`. Nothing else. If you need more than that, then your crate is too big.

So rationalists are just completely nuts, huh?

If anybody, man or machine, is telling you you’re special with unique spiritual insights there is a 100% chance it is not working for your best interests

My favourite WMC is/was in the small town of Idle, near Bradford: the Idle Working Men’s Club. Also home to a pub called the Idle Cock, which gave me great amusement as a twelve year old

still the first urban dictionary definition

Oh cool, the Tokio LIFO slot is stealable now! I'd totally missed that after the Oxide and Friends episode on severe latency caused by the Tokio LIFO slot optimization, @elizas.website made the LIFO slot stealable, so you can avoid the issue without turning the optimization off!

The white-hot take here is that Display itself is a mistake and should not exist as there is no inherent way to display and data to the user (without input from a presentation layer including localisation and accessibility, etc)

I think having Display as a super-trait of Error is a mistake. There is no reason that an error must be presentable to a user, some should always be handled. Furthermore, the presentation of an error should be separate from the error itself, using Display encourages sloppy error reporting

It’s only been a few years since I left Microsoft, it when I was there GitHub seemed well run, respected but the wider org, and a high priority for Microsoft’s developer strategy. It’s hard to believe how badly things have gone wrong. I’d be fascinated to know what has happened

Two sub-two marathons in one event is stunning

Rust 1.95 released last week (blog.rust-lang.org/2026/04/16/R...) and has a few cool things in it. `if let` guards might look niche, but I think they solve the last reason for having nested match expressions where it doesn't feel 'right'. Not a huge deal, but nice to scratch away that itch.

I had forgotten that `cargo publish --workspace` was stabilised back in Rust 1.90 (blog.rust-lang.org/2025/09/18/R...). So good!

derive `Display` when? This would be so useful and a relatively easy lift, I wish it were in std

Welp, I got laid off. RIP futurewei OSS rust team. If you know anyone hiring systems engineers lmk.
