On Alphamom, Lindsey "Filth Wizardry" Boardman shows how she and her kids made cookie-stamps out of salt-dough (they also make them out of polymer clay, but this is not recommended for use with things you plan on eating). The stamps let each kid customize her cookies, which resolves ownership squabbles and also adds aesthetic appeal.
I made them some handles from the salt dough that we could glue on once they were baked solid. The trick with salt dough is to bake it long and slow so that it doesn’t have any problems with air pockets distorting it. We left ours to air dry overnight and then I popped them in the oven on a low heat to finish them the next day.
Happily we found that the salt dough stamps worked nearly as well as the polymer clay one had! Although they are unlikely to last as long or be as easy to clean.

Zero-knowledge proofs are one of the most important concepts in cryptography: they’re a way to “validate a computation on private data by allowing a prover to generate a cryptographic proof that asserts to the correctness of the computed output” — in other words, a way to prove that something is true without learning the details.
Retroworks’ $18 decoder rings don’t have much by way of cryptographic robustness (they compare disfavorably to the cipher-wheel wedding rings my wife and I wear!), but they’re not a bad way to introduce the littlies in your life to the idea of habitual secrecy. (via Red Ferret)

Although fully autonomous vehicles aren’t yet allowed on public streets, they are poised to dominate the roads in the not-too-distant future. But before that happens, Apple, Google, Uber, and other companies now investing in self-driving tech are going to need talented developers that can account for the dizzying array of factors at play when a […]
