Heh :)

Oh, wtf, I'm 3/4 through integrating X-Wing KEM into my project and it turns out it *cannot* authenticate?? This is such a weird thing: - Hey, we invented HPKE to make using crypto easy! - Hey, we invented post-quantum HPKE (which disables half of HPKE, making it a mess again, but who cares).

@filippo.abyssdomain.expert I've been digging into the Go Argon2 code and I think the recommended settings is wrong. The docs state "[RFC 9106 Section 7.3] recommends time=1, and memory=64*1024 as a sensible number." Section 7.3 is a different section, and 7.4 recommends 1/2GB or 3/64MB.

The USB-C flavour of the Ark I is functional! The connector positioning needs a bit more precision though, it's not a snug enough fit for my taste. On the down side, the CNC job leaves a lot to be desired. Annoying how good it is, yet how far away. You win some you lose some 😅

Tonight I benchmarked some #Rust tokio framing mechanism. The encoder was allocating like crazy. Nerd sniped till 2:30AM, but hey... :) No, I didn't fix tokio, I just dropped it and reimplemented the framing code myself.

Just published a new #Rust crate: darkbio-cobs! It is a reimplementation from zero of the COBS encoding format. My library is ~5% faster at encoding; and ~275% faster at decoding than the standard Rust `cobs` crate. 🤓 crates.io/crates/darkb...

How hard could it be to outperform the most popular #Rust COBS library that has 17 million downloads? Apparently, not that hard. At least it took... like 10 minutes. 🤪

Yesterday evening I wrote my first ever Rust benchmark. Today: Look ma', made the Rust cobs decoder 20% faster 😅 github.com/jamesmunns/c...

Time to order a box from China: 30 mins Time to design the box: 1 hour Time to manufacture the box: 2 days Time to ship the box to Romania: 2 days ... Time to get it past customs: 10 days 💀

More like by popular dropping-the-Ark-on-the-floor because "hey, does this magnet hold it"... but you get the picture :D

Always that damn paperwork... 🤪

"A UPC (UNIVERSAL Product Code) is a 12-digit barcode used in North America to identify most products. [...] The rest of the world uses 13-digit EAN (EUROPEAN Article Number) barcodes to identify products." Someone was skipping geography classes... 😆

Threw a bunch of images at Gemini, damn…

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.

Nice and crispy 🥰

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 🧵

I think I’ve been scammed… my 3D printer seems to print weird 😅

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!

By popular demand and a a bit of self reflection, USB-C is the new contender for the @dark.bio Ark. Board ready for production.

🤪

@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?

Yeah, this is not the flex you think it is.

Find me next week if you want to see these live 🩶

Final assembly before heading to the airport 🥰, see you in Argentina! 🇦🇷

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.

Happy to announce that we've been granted a USB product ID under the Raspberry Foundation vendor umbrella! Thank you @raspberrypi.com!

Swaaaag :) (limited edition mind you, I gotta like you (or make a good impressiond) to give you one :P)

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". What the actual dafuq...

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 🧵

One step at a time, slowly, but getting there.

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. #Romania

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 😅

Spent half an hour looking at this 🥹 Okochi Sanso, Kyoto

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

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 🤣

Me 9 months ago: "Imma make a genomic project so I won't need cryptography"... 😁 Me today: "Myeah, ZK membership proofs look like something I need"... 😭

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.

My CBOR code was just patched up with a fuzzer and a crash-fix, courtesy of 0xalpharush 😎 Thank you for your contribution to @dark.bio :) github.com/dark-bio/cry...

Your genome is the essence of what makes you, you. Nobody can be trusted to safe-guard that. No laboratory, no company, no government... not us. It's your responsibility to keep your genome private; and our mission, to help you do so!

How hard can it be to write a CBOR codec? 😅 6 hours and 1200 LOC later, I have my own #Rust CBOR encoder 🤪 Go break it if you can ;P github.com/dark-bio/cry...

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.
