Still think Swatch's .beat Internet Time for living without timezones was such a solid idea. For web-supporters, cyber friends and everyone else!

Just went to their flagship store in Marseille and they said it's been discontinued for a while. I'd buy one right away.

"How to shoot yourself in the foot when things go swimmingly" – A short story of the rise, fall and rise of a small macOS app I published last year.

TLDR;
1. ASO with @TryAstroApp works. Like, really, really well.
2. Nothing can save your app, not even ASO, when you stop caring.

Noted. Using my Luminette before breakfast affected my sleep-quality more than using it throughout the day.

LOL, got 100% nerd-sniped by my friend Sönke this week and wound up building a small spaceship.

On Monday he's like "Hey, what if you found obscure seed phrases embedded in public texts? You'd only need to remember the name of the book and the paragraph and go from there."

I honestly could care less about crypto(currencies) and I'm 100% sure this is like cryptanalysis 101. But, yeah, it seemed like an interesting problem anyways.

First, I downloaded a few hundred books from Gutenberg, wrote a ruby script and found BIP39 word sequences with a tolerable buffer for filler-words.

Then, I was like, okay, gotta now check them against actual addresses. Downloaded a list of funded ETH addresses. Wrote the checker in ruby. Ran it. No hits but this was now definitely weirdly interesting.

Because: And what if I downloaded the whole pg19 text corpus to scan! And what if I'd add BTC addresses! And what if I checked every permutation of the seed phrase!

Everything got really slow once I got to processing 12G of raw text for finding sequences and then checking a few million candidates with 44.000+ variations per candidate.

So, let's rewrite this into C! And since I've got 16 cores, let's parallelize this puppy! And since it's a MacBook, let's use GCD! Optimize all the things!

Lol, so NOW this thing is so fucking FAST. Takes four minutes to go through the full pg19 corpus and generates 64,205,390 "interesting" seed phrases. The fully parallelized checker (see Terminal screenshot) processes 460 derived addresses per second.

I really don't care if I get a match or not. I feel like I started with building a canoo and wound up with a spaceship is in itself just the best thing in the world.

Anyways. Just wanted to share this. If anyone wants, I can put the whole thing on github, too. Let me know!

@haydendevs Wrote down an idea around this yesterday - basically have LLMs generate text using homoglyphs. Which would be perfectly readable and verifiably of non-human origin

Quoting @SpringStreetNYC · Dec 6, 2025

Idea for "marking" AI-generated text: Make a final pass that replaces the regular letters with UTF8 homoglyphs instead. Still 100% readable and verifiably of non-human origin.

Case in point, here's the homoglyph version of this message:

ꓲdеа fоr "mаrkіոց" ꓮꓲ-ցеոеrаtеd tехt: ꓟаkе а fіոаꓲ раѕѕ tһаt rерꓲасеѕ tһе rеցսꓲаr ꓲеttеrѕ ԝіtһ ꓴꓔꓝ8 һоmоցꓲурһѕ іոѕtеаd. ꓢtіꓲꓲ 100% rеаdаbꓲе аոd νеrіfіаbꓲу оf ոоո-һսmаո оrіցіո.

This is actually the biggest danger: that workers still have to keep it a secret that they use AI at work because so many employers still think AI is still at the GPT-4 level.

I would say it's pretty performance but, the actual cryptanalysis is very naïve. I call it a cute-force attack 😁

This conversation doesn't need to be covert either. In fact, I think that AI-generated text should have it's own visual voice! And it looks like, for the Latin alphabet at least, there are several 'typefaces" that could be built.

There was a short-lived exploration into writing a Metal shader for a part of the pre-processing. I got pretty far but I backed out because it was slower than running things in parallel.
