github.com/conradludgat... Managed to combine all of this into a format I'm happy with. I've got both FIPS support for v3, libsodium support for v4, RustCrypto support for both. I'm using generic tokens but also exposing type aliases for ease of use.

my power move is pouring hot water into an empty tea mug and then simply walking away

Considering rewriting my paseto/paserk impls atm. PASETO V3 features only NIST algorithms, whereas V4 features only libsodium/nacl I'm wondering: 1. Does it make sense to keep v3 and v4 in the same library? 2. If you need v3, do you also need FIPS?

Amazing how fast Hollow Knight stopped being one of my most beloved games given how toxic the community has become since silksong came out :/

The full moon before the lunar eclipse is so incredibly bright right now. I had to lower my ISO and shutter speed as low as my phone would let me to get any detail whatsoever

I urge companies to take funding contributors seriously, in ways that aren’t tied to projects and goals. Being a generalist in the compiler meant that often I wasn’t working towards a roadmap, but my contributions *always* paid off in the long term extensibility of the language.

Good morning, Seattle!

When working with async, you often need to call a function that would block the runtime. Turns out not all blocking functions are the same Tokio defines two kinds of blocking functions: IO bound and CPU bound. A close read of the tokio docs tells you to avoid CPU bound tasks in spawn_blocking

I can't stop thinking about her github.com/zed-industri...

Would you be impressed by a 5% performance improvement when serialising with serde_json?

⚙️🦀🥝 What's Rust Forge Conf 2025? I'm glad you asked! p.s. Engagement really helps. Replies, likes and/or share to receive a discount code via DM.

I wish we had spaces to collaborate on technical work where being a jerk was just not allowed. Like, actual proper fearless moderation. Your reply starts with "No." on its own line? Two weeks ban. Learn to behave. You go on a tear about another participant? One year ban. No warning. Bye.

I'm back, babbyyyy More async coming your way at @rustconf.com. I've spent many years writing software with async Rust. It's a great tool but easy to misuse. Sign up and I can teach you some of my knowledge to kick start your teams.

Unfortunately I can't make it, but Tim is amazing and I know y'all are gonna have a great time in NZ 🔥🚀🦀

🎉 Speaker lineup announced! RustConf 2025 is bringing together some of the most exciting voices in Rust — from global adopters to project maintainers to AI researchers and beyond. Explore the full speaker list → rustconf.com/speakers Full program and registration to come! @rustfoundation.org

Super excited to share that I'll be giving a keynote at RustConf 2025! Lineup: rustconf.com/speakers/

I love my job. It's so cool to have a serious reason to play with microoptimising data pipelines and distributed systems. Right now I'm starting a hobby project to recreate the Neon architecture - requires Paxos, LSMTrees, io_uring, etc. So many interesting components in one system.

Someone here nerdsniped me into researching AEGIs recently. I forgot who, but I blame you for this github.com/conradludgat... My AVX512 rust impl of AEGIS-128X4 can get 60GB/s encrypting 16KiB blocks on my Ryzen 9 7950x per thread. Absolutely wild. Anyway, it was a fun project.

Sponge functions are really cool

As I get more senior with work and as I pick up more challenging side projects, I had noticed myself finding it hard to focus. More senior tasks at work involve more meetings and more long-term epics. More challenging side projects required a lot more motivation to overcome the obstacles.

I like watching maths content on YouTube. Recently a bunch of maths/CS channels have been posting more and more cryptography videos. I like cryptography, and these videos are decent at explaining the specific concepts, but they get some of the pragmatic/realistic parts so wrong.

Someone asked me if there was an async semaphore that supported two counters. They didn't want to have two queues. I've written many semaphores in the past because I've needed just a bit more control. I figured out though how to make it generic, so I started working on docs.rs/flag-bearer/...

Surely this new video won't make me seem like a crank. www.youtube.com/watch?v=QEJp...

🦀 Rust 1.85.0 has been released! ✨ One of the bigger #rustlang releases in a while, as it contains *async closures* and *the new Rust Edition*: Rust 2024! 🎉 blog.rust-lang.org/2025/02/20/R...

Workshop day at @rustnationuk.bsky.social 🥳 time to shill async some more

People complaining about needing dependencies in rust really out here acting like we're struggling with our small std lib. No, it does not cause me physical pain to `cargo add rand` and I will not think twice.

WIP multithreaded string interning crate github.com/conradludgat... Code is minimal (thus easier to audit). Perf is pretty good

"Atuin solved all my problems with history" "It really is a game changer for working on the console and I can't recommend it enough" For years I just wanted to make something that people used, and I'm super happy to have done so ❤️

Okay this is more viable than I anticipated now I feel like I have to flesh this out. I think this is what you could label as actual first class IDE support for macros. I am astonished at how well this works.

PSA: if you're shipping a CLI tool in Rust, please give an option to use the system certificate store. Most Rust libraries for network stuff will just use the Mozilla webpki list by default.

FWIW we wrote some text here to try and encourage rustls-platform-verifier use: github.com/rustls/rustl...

highlighting this banger comment from Alice on the Rust subreddit

rustls 0.23.22 was released today, which adds support for X25519MLKEM768 (previously available in the experimental supplementary crate "rustls-post-quantum")

FYI I've published a fork of dashmap that I've been working on for a while crates.io/crates/clash.... Main goals: * remove as much unsafe as possible. * keep high performance. Side goals: * improve the usability of the API * double down on sharding capabilities

> I treat AI as I would a collaborator or a pretty good intern I find this take very weak. I like nurturing and teaching interns. I like working with someone who I know will actually learn from what I tell them

You can no longer buy tickets to have me infodump for 6 hours :(

we've been working hard on addressing early beta feedback for Atuin Desktop in the past week - dark mode (y'all kept asking) - improved collaboration UX - custom terminal fonts - fixed several sync & performance issues

Sponge functions are pretty cool

I was gifted a RaspberryPi Pico2W this week. Thought it would be a good opportunity to see if I could get github.com/conradludgat... running on it as that was one of my goals. I'm happy to say that with a little bit of tweaking I managed to get it to work github.com/conradludgat...!

Now that I'm at a rust meetup, my stress level has dropped from 60 down to 40

Me: "I am apparently stressed" quoting my fitness watch's stress measurement Wife: "That's because you're doing kubernetes" pointing towards what was on my monitor. She's really not wrong

This was the cutest commission ✨️💓 A happy family of cats with punk collars #digitalart #cats #petart #art

Hot take? Is it weird that I actively avoid recursion and instead go out of my way to maintain custom stacks to use with loops instead?

Hey, if you're looking for a reason to avoid social media today, make it about acquiring a copy of www.imdb.com/title/tt2384... to watch. (The British Channel 4 version, avoid any copy on Amazon Prime)

The best programming language is the one you are good at and feel productive in. For me that's Rust.
