I'm trying a new "see how well AI image gen is" test. This time I'm going to ask it to draw a map of the world, and then zoom in to Europe, the UK, Yorkshire and York to see when things start to get hazy.
All of these are with the free models using the smart/thinking variants. 1/n

The Conscience of a Hacker, also known as The Hacker Manifesto, turns 40 today!
Written by Loyd "The Mentor" Blankenship, its spirit still resonates with hackers and makers everywhere. A cornerstone of hacker culture.

I realised, of course kids can understand quantum... Assume ‖Gender‖²; if a kid asks their mum a question, ans yes/no are equally likely. That's superposition. Once they get the answer, it won't change. That's measurement. If they want a different answer, they ask their dad. That's entanglement.

New incredible detail here: ICE says a match in its facial recognition app Mobile Fortify is a "definitive" determination of a person's status, and that this overrides birth certificates. This is an app ICE is using in the field to scan people

When I was in undergrad our engineering building had old computers set up in a little museum/history section and they included the first Macintosh from 1984
