Starting to pick up speed in Rust too 😅... 1.5days of work (no AI :P).

Well, this took a cool 3 months for Apple to approve.

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 🧵

Today I bought a small, cute pumpkin as a garden decoration and placed it beside my gate to cheer up anyone passing by.
32 minutes later it was stolen.

Is it just me, or is @signal.org down? It fails to connect both on my phone and laptop; on any of WiFi, mobile data or VPN across different countries. First this this ever happened.

Ordered 10 custom cables. Took a month, they arrive. Pick one, doesn't work. Pick another, doesn't work.
Sigh. Report them borked. Start debugging, GND connection missing. Dafuq?
Days later, try 3rd one. Works. Wat? Turns out 8/10 work and I randomly drew both faulty ones. 🤪

When I was 17, I was playing an online quizz game and figured how hard can it be to automate it.
Ended up implementing HTTP on top of raw TCP, the entire flash game net protocol and even a web dashboard and “AI” that chatted with players.
Took me two weeks. Didn’t know it was supposed to be hard 😅

When I was 14, I saw a problem and came across a neat solution and thought, “can’t be that hard.”
Was ridiculously laborious and so it turned out I was the first and only person to ever publish something like that open source. It is in wide use.
It taught me skills that directly aided my career.

Waking up at 3:30AM to try and get a ticket to the Ghibli museum (Mitaka, Japan) is absolutely worth it!
Took 3 trips to Tokyo across 2 years to finally get in, but it’s such an amazing place 😊

Ended up wrapping PBKDF2 too in my #rust crypto library. It's excessively simple, but I wanted a single library to depend on in the @dark.bio #flutter mobile app with a single version bump needed to add features / fix existing ones. It's turning into quite a nifty crate. 😊

Hi, it’s me, your neighborhood robotics business guy, to inform you that if robots were actually ready to automate a process at scale, they would likely already be deployed
Fascinating interview with Commerce Secretary Howard Lutnick on @cnbc.com this morning: He said that US manufacturers can use robots to offset the low wages paid in other countries, enabling the return of more production to the US, and Americans can get jobs building and maintaining the robots.

Hahahaha, I moved the eMMC chip off a @raspberrypi.com
onto my own board. Disk speed got hit by 50%.
After investigating, turned out the RPI drivers set external eMMCs to low speed (why?!). So I overrode it in the driver... worked.
Problem is... now my reads outperform the RPI 🤣

Just to highlight the insane amount of attention to detail that goes into the @dark.bio Arks:
I bought thousands of SIM card ejector pins and I'm not stopping until I find one that looks good and doesn't oxidise or rust under harsh conditions 🤪
The shiny ones just arrived!

Heh, reached the point with my @dark.bio hardware where assembly requires x-ray inspection ☠️
Yeah, the tracing will get some more love, here I just wanted to see if it works at all before cleaning it up.

I've been using CBOR via the `ciborium` #Rust crate for the cryptographic signatures (data encoding) in my Dark Bio project.
I've restricted it quite a bit, disallowed most types. Today I found that unfortunately it's still problematic, possibly beyond fixing for security uses.
