I read that article when it came out and thought it was well written and had good evidence and sources. It's the opposite of unhinged IMO, and explains a lot as to why Google is as terrible as it is now.

There is indeed: Bezier::compute_lookup_table[1]. You'll want to use a `TValueType` of `Euclidean` to get equidistant points.

I suppose they're being pedantic in that the Channel Tunnel only carries rail traffic.

Completely agree. I'd be tempted to put up some Rust code if the contribution pipeline wasn't such utter crap (yes yes it was good for it's time, but that was decades ago).

But I won't be putting up any code either way until the culture moves on from little kings calling things they don't like (and that don't really affect them) "cancer". I'm not holding my breath.

I've started wondering what's next after Linux because it doesn't feel sustainable long term any more. There's a small trickle of fresh blood but not enough to keep the kernel project healthy IMO.

You can! I needed to run some realtime networking stuff on an isolated core and followed this [1]

I used Windows 11 and the two cores I isolated show no CPU usage in task manager until you run something that's pinned to those cores.

Need help with Rust in your EtherCAT deployment? I'm your guy! I'm available for contracting roles to help you implement or debug Rust EtherCAT applications using https://github.com/ethercrab-rs/ethercrab. I've helped various companies implement their first Rust control systems, as well as tune the base Linux installs for best realtime performance.

Hello! I'm James and I'm keen on working in robotics and automation. If you need help implementing industrial control systems in Rust, I'm your guy! I'm well versed in EtherCAT as author of EtherCrab[1] but can be of service for other protocols like Modbus, along with tuning Linux for realtime. Do get in touch!

Senior Rust programmer with 6+ years working in the language full time, ranging from web backends to embedded Linux IoT services. I'm looking for Rust work either in industrial automation with EtherCAT or `no_std` and microcontrollers.

I'm the creator of EtherCrab (https://crates.io/crates/ethercrab), a pure Rust EtherCAT controller, borne out of frustration from the field of C/C++ implementations out there. Do you have a Rust automation application that needs EtherCAT? Let me know!

If not, maybe you're interested in hiring a `no_std` embedded Rust developer. I'd love to discuss a full time role if you're willing to take on a fast learner with a good hobby background in writing software for microcontrollers.

Built into `cargo`, I'd recommend `cargo tree`, `cargo tree -i` and/or `cargo tree --duplicates` to figure out where certain types of dependency tree bloat are.

We use it a bit for https://github.com/embedded-graphics/embedded-graphics and I have to say I love it. It's just the right balance between configuration variables/constants and "a folder full of bash scripts". I highly recommend giving Just a try.

I always get a bit excited when I see a righto.com post.

An excellent read as usual.

If you’re a library/tool author, please put a small code demo in the readme, or at least link to some. I’d like to see what the syntax looks like at a glance. I think it helps adoption for all projects, including this one.

I'm not affiliated in any way, but Dave Addey's book of the same name as the blog is fantastic. Highly recommended if you're into weirdly specific stuff like why there's specific text on the motion scanner Ripley uses in Alien. (spoilers: IIRC it's just Letraset gibberish)

As I understand it, the Quake RTX demo is fully ray traced but I could be wrong on that. The FPS isn’t super high but definitely playable.

More "mechanical" stuff like typos in payload fields and deserialisation is MUCH safer (and more pleasant with the derives!) due to the benefits of Rust's type system, but broader stuff like authenticating requests and user roles is still up to the user to implement well for a web app to be safe. IMO the language helps a ton here too.

Performance wise, I don't think I need to repeat half the internet here, but I'll just say you'll be blown away by how little RAM a Rust app/container uses for the number of users hitting it. YMMV of course ;)

Just to throw some anecdata back at this overly broad statement, I use Rust full time at work and maintain some embedded crates with moderate download numbers. I suppose I mustn't exist then?

Still reasonably early days like the rest of the ecosystem, but there is good support for a lot of ATSAMD and ATSAME devices here (https://github.com/atsamd-rs/atsamd).

I'm not very familiar with the ATSAM* series so compatibility-wise this might be wrong, but you could likely add ATSAML support to that repo reasonably easily.

It might not help judge performance for individual tasks, but PassMark's CPU listings (https://www.cpubenchmark.net/cpu_list.php) should help with relative performance. The results have a multi- and single- core score which should help comparing different workloads.
