In honor of Meta's latest announcement, a thread on 175 years of 3D failure.
Let's first go all the way back to 1851 with the Brewster Stereoscope. No less a person than Queen Victoria was impressed, kicking off a fad that quickly sold over 250,000 units. Turns […]

Looks like the first carnival costume our kid is choosing for himself will be... Spider-Man. A bit late to convince him that Son Goku is better, but not bad. Not bad.

Welp, did a big refactor of my animation library that was supposed to make things simpler. The code for my test animation is now... 19% longer than before. But it is simpler to write and understand, I guess... We will see...

Opened up Babbel after a while. It randomizes the order of the answer buttons, which is nice in general. But it's absolutely terrible UX for yes-or-no questions.

Never really been bothered by daylight savings. But now, with a young kid in the house, I will curse all the gods twice a year.

Okay, I don't want to make it "a thing", but: my maths YouTube is muddling along mostly due to a lack of motivation on my side. Will still do videos there, but with even less regularity. Alas, I like to create things and talk about it. So, I started a new channel about game development! Come […]

After weeks of rummaging through moving boxes, I finally found my Kamvas! And in our new office space, there's enough room so that I don't have to clear the desk before using it!

Spent the day, among other things, explaining to two lecture halls full of new students where to find their courses online, how to write e-mails to profs and what to watch out for when they use gen AI. Very exhausted, but it went well.

Our kid got a children's bible. Obviously, it is very simplified and abridged. What surprised me was that they kept how Josef doesn't want to marry Maria any more after he learned that she is pregnant.

Mathematicians occasionally uses "tack" symbols, ⊥ and ⊤, for various purposes. They're called that because they look like thumb-tacks from the side. But if you need a particular tack, what do you call it? Is "⊥" the "up" tack, because the pointy bit is up? Or is "⊤" the "up" tack, because it's […]
