Look at me I'm posting an image from another social network like a basic bitch.

But THAT social network has typesetting 😀 and so the post reads nicer than if I retyped it here with no typesetting.

My 5y/o had the lovely idea to be a jewel thief, and so we did this bit all over the faire where he would pickpocket my jewels and I'd yell "Thief! He's getting away!"

One small update to "FHE and the public" (www.jeremykun.com/fhe-and-the-...) includes a link to Apple's RWC talk and a note about one slide I found interesting in re Apple's stance on privacy.

A badly lit photo, but this was the main claim from Apple in the talk about the promise to the users

A nice note that privacy prevents a lot of metrics gathering, you can't know if your method is successful if it's fully private!

Sunday night, as good a time as any to make a Mobius kaleidocycle hannes.home.oist.jp/kaleidocycle...

Anyone want to go in for a group order of this "crypto means cryptography" shirt? I just kinda threw this design together but I like the retro theme with a modern mantra.

One of the very first digital photographs ever scanned was this photo of Russell Kirsch's 3-month-old son, Walden. Scanned in 1957, it's a 176x176 grayscale image composed from multiple 1-bit scans with varying intensity thresholds on the scanner.

This cherry blossom tea from Korea is just divine.

Heh, the first result isn't quite what I had in mind, but the second is, and I like how I don't have to sign up to try it.

They looked like this before painting. A nice routed edge to make it look nice.

I would love to have a hand-crank-driven Comptometer: https://en.wikipedia.org/wiki/Comptometer

This thing looks so cool! And it has the 9-s complement digit on each key so that you can subtract without turning the gears backwards

Do you want more math content? Because that's how you get more math content. Aperiodic monotile scones.

Wrapped up math circle for the summer. One of the kids wrote me a nice note. ☺️
