I worked through @ProfTomYeh's Deep Learning Math Workbook[^1] over Christmas and learned SO MUCH by doing so.

Today I learned AI by Hand Academy[^2] which I would subscribe to ($29/mo. is a no-brainer) instantly.

Professor Yeh: When I click on the "Become a member" button, I get redirected to the login page without the option to register.

  • Could you send me the academy-registration link if it exists?
  • Or should I register/subscribe to the paid Substack subscription instead/?

Just sat on this steel bar stool at t.co/60NA9eoOur and HOT DANG! They're shockingly comfortable to sit on. And they're pretty. And sturdy. Well done, @zarahome

Context: I'm playing around with a mobile app I've wanted for a while. I built the first version for iOS mostly because I really like Swift. Problem is, I can't really device-test it because I use a Xiaomi 14T (Android) phone.

So, with Claude Code and the iOS code, I "cloned the app to Android" today. It's a tiny app so that only took 2 hours. (Which, in itself, is totally bonkers of course.)

Now, what I actually want to say is this:

Why is everyone always hating on @AndroidStudio's self-titled IDE? I don't get it.

It's working really, really nicely for me. It's well-designed. It works. It's hassle-free. It's snappy.

Sure. It's got a memory footprint of 6GB. That's not ideal but honestly, I've got 128GB of RAM and the overall experience with Android Studio is great. And it's running my app in a full virtual simulator and on my physical device.

It's a GOOD IDE. It's a GOOD DX. Maybe not my favorite, but I for one had a good experience and am grateful for the work that their team put into the studio.

Thank y'all. Good stuff!

Thank you for the heads-up!

Immediately bought it as a birthday gift for my wife. And hopefully she'll let me read it too 😁

Thank you for the reminder for both, the idea and how well this was written.

"... Luck Surface Area, is directly proportional to the degree to which you do something you're passionate about combined with the total number of people to whom this is effectively communicated. ..."

That's a banger summary IMHO.

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.

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!
