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

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.

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