May seem small but #FerrousSystems donating their
#rust spec is huge.

In #lua, it's helped so much to design things like #luajit and custom embeds. 😎

@FerrousSystems using mem::take() to reduce heap allocations in rustls.
(Also wen hybrid Kyber support? 🥺)

I'm also working on a new venture with @Argorak, @Xylakant, and @spacekookie, (which is why I've been a little quiet lately). It's called @FerrousSystems, and it has a lot to do with Rust. I'll share some more details about that later, but I am v excited about it :) 3/3

I had to go digging in some CircuitPython, but I have basic Row/Column scanning working already! Just outputting keypresses for now via @FerrousSystems' `defmt` logging

@rustembedded + @makerdiary

Okay, I think that's it for today, I'll pick up later with the next point.

Here's my plug, if you like this, let me know, and if your embedded team needs help, reach out to me or us at @FerrousSystems! We help with this stuff a lot, in Rust and in other languages.

Any #Seattle/Bellevue rustaceans out there? I'm in town until Sunday, if anyone wants to grab a coffee or a beer and chat about tech (or whats going on with @FerrousSystems), let me know! DMs are open

Hey, so a cool thing happened on Friday. @FerrousSystems is now officially a GmbH (in Gründung), so I get to add "Managing Director" to titles I've held.

Check out <a href="http://ferrous-systems.com" class="hover:underline text-blue-600 dark:text-sky-400 no-card-link" target="_blank" rel="noopener" data-link="bsky">http://ferrous-systems.com to see the cool (#rustlang) stuff that @Argorak, @Xylakant, and I are working on :)

Celebrating little milestones: @FerrousSystems is no longer "in Gründung".

Packing up for #35c3! I'll be there along with some of the other folks from @FerrousSystems, send me a DM if you want to meet up or chat about #embedded, #async, or #distributed @rustlang!

Shameless plug, if this sounds interesting to you, please get in contact with me (DMs open), or my company, @FerrousSystems!

Here's my sales plug: If you're interested in @rustlang (on or off of #embedded systems), reach out to us at @FerrousSystems.

We've helped folks move production embedded systems to Rust, and are happy to evaluate, help, train, or advise your company if you need assistance.

On my way to @emBOconference, I'll be there today and Saturday, and giving a lightning talk about @rustlang on Saturday before lunch!

Let me know if you want to meet up and chat about @OxidizeConf, @FerrousSystems, @rustembedded, or anything else #embedded related!

Feel free to comment if you have any questions, or DM me or @FerrousSystems if you have any requests you'd like to discuss!

@Decawave Hi there! I have a question about a partnership with @OxidizeConf, run by my company @FerrousSystems, would it be possible to have someone from the Decawave team send me a PM for how I can get in contact? Thank you!

At @FerrousSystems, we're also exploring how things like async/await can be used to write concurrent, linear code, for cooperative multitasking, without having multiple stacks (see https://ferrous-systems.com/blog/async-on-embedded/).

You still get all the awesome compile time...

We've taken the "bigger is better" approach to stickers at @FerrousSystems. Here is @Xylakant showing off his company spirit! Let us know if you want one for your laptop, large vehicle, billboard, or spaceship!
