Rust constants are slowly but surely getting more powerful! On stable you can parse constants from environment variables. I remember having to pull in weird crates & macros to be able to do this. #rustlang

$const TASK_COUNT: usize = { let input = if let Some(string) = option_env!("PERFMON_TASK_COUNT") { string } else { "16" }; match usize::from_str_radix(input, 10) { Ok(val @ 2..) => val, Ok(_) => panic!("PERFMON_TASK_COUNT must be 2 or higher"), Err(_e) => panic!("Could not parse `PERFMON_TASK_COUNT`"), } };$

Awesome stuff. Wish I'd had this at my previous job

I usually just sit in any seat nowadays tbh. It's a bit of an annoyance on both sides when someone else asks you to get up because it's their seat, but better than potentially wading through a busy train

I've added an AI policy to ripgrep that was shamelessly copied from uv's policy. I plan to add this to the rest of my projects, but if anyone wants to offer feedback on wording, now would be a good time! github.com/BurntSushi/r...

lgtm - this seems quite similar to the policy I ended up writing for `rig` back when I was lead maintainer

I'm leaving the Playgrounds team in a couple weeks (aka, the team that maintains the `rig` family of crates). Pretty happy with everything we've done. If you are eager to see where I'm going, check my GitHub profile. If not, wait a couple of weeks before I do another post I guess

I'm glad the community at large is starting to realise that this is going to be a problem if left untackled. On the project I work on, I've added my own policy on AI-involved PRs. Pretty much just says contributors must be accountable and to state when the PR has been majority AI generated

See how Gleam gets the job done in production ⭐ Full case study coming soon: “For a team like ours, with many other priorities and projects we need to work on, the confidence that Gleam gives us is worth its weight in gold.” - Edward Kelly, Director of Technology at Strand.

Graphic with a headline "Gleam in production" and a quote: “Adopting a new language is always a gamble, but Gleam has paid off. The belt-and-braces approach to safety and fault-tolerance has given us a system that just works, reliably, day in and day out, without constant babysitting and maintenance.” - Edward Kelly, Director of Technology at Strand.

Excited to be releasing rig v0.14 soon! Many new features to come and I'm also working on many more over the next few weeks to make the library (and its experimental counterpart rig-experimental) way better 🙂

the best part about early computers is they hadn't settled on the term "instruction" yet and many systems called them "orders"

Each pernissible operation can be specified in a concise
coded form called an order. The correspondence between the set of permissible operations and the set of orders which specify them is called the order code of the Illlac. It is given in detail In Chapter
3. A coded problem is called a program or routine.

I just wrote a blog post on exploring and recreating Axum - Rust's most popular web framework (probably!) - from the ground up. We explore routing, extractors, state, and middleware. Take a look: joshmo.ooo/blog/explori...

Exploring and (minimally) recreating Axum

Let's learn how the Rust web framework Axum is made by analysing its core components, then re-creating it.

after this side project i might have to write a mini-guide on the bollard crate lmao

i don't think poem is too bad (esp. considering openapi stuff), it's mostly just that axum and dropshot have entire teams allocated to them whereas poem and some of the other frameworks are basically a bus factor of 1

😂 Someone called one of my old articles that I wrote "AI-generated garbage". Yes, the article and repo is probably outdated. I don't work for the company I wrote it for anymore. But it's definitely not AI generated.

for my js devs (or devs that are forced to work with js for their day job): are you using js registry? i'm actually curious on what the consensus is now that it's been out and the initial novelty has worn off
