The rest of the world uses 13-digit EAN (EUROPEAN Article Number) barcodes to identify products."

We haven't got any certification work done yet, but one step is figuring out what and where needs to be highlighted on the Ark. First prototype etching done.

Was playing around with laser marking the @dark.bio Ark I devices. (Yeah, why do it in a fab professionally, when you can yolo it yourself?)
It's probably not news to anyone who ever did it, but imma share my progress anyway :D :P 🧵

Hey @yubico.com , I assume no key or HSM currently supports ML-DSA / Dilithium. Are there any plans for a hardware release to enable these PQ constructs? Ty!

@filippo.abyssdomain.expert do you have a suggestion for hybrid ecc&pq signature schemes similar to the hpke one you’ve been posting about lately?

Swaaaag :) (limited edition mind you, I gotta like you (or make a good impressiond) to give you one :P)
Our founder, @karalabe.bsky.social, will be attending @devcon.org in Buenos Aires in 2 weeks and will have a few "business cards" to give out.
Now, we're not saying that these are functional... but we're also not saying that these are non-functional ;)
Come (or rather go and) say hi!

The first full time engineer joined my @dark.bio project! 🎉
His 2nd PR was putting a splash screen on the Ark I boot screen. 🙈
Seems I've found my match wrt attention to detail... 😅

The joys of hardware prototyping...
Ordered a board, took a month to arrive. There's a single faulty $0.3 analog button on it, making the entire thing unusable 😭
Fixing it properly would need a $1K tweezer, or a $2-4K rework station.
Yoloed 😅... tore off a pad 🥲... works 🙃

An app crashes while using my YubiKey
ChatGPT: It's because your YubiKey has Ed25519 keys in it. Solution: "Reset the PIV applet. This wipes all PIV keys/certs".

Ugh, today was a long day...
I've set out to configure a @mattermost.bsky.social instance for my @dark.bio project. It... didn't end up as I planned in the morning 😅
First up I had to convince Hetzner that my account is legit, because is seems Eastern Europeans are fishy 🧵
