What kills me about this story is that Meta’s public CSAM scanning clearly does not work, if they’re delivering ads for CSAM content. But this failure will be used as evidence that we need to add scanning for private and encrypted messages. www.bbc.com/news/article...

The best concrete bit-security one can achieve for a dlog-based construction on a 256 bit algebraic group is 128 bits, right? Well, usually yes, but sometimes, somewhat surprisingly, better concrete security is possible:

When the Germans finally took my family's village in Greece in 1944, they lined up every man between 6 and 80 next to the church and shot them while the women watched. This feels like that.

Actually, it’s worse than this Not only was Musk completely ignorant of what USAID did and how many lives it saved He also called it a “criminal organization” that “needs to die” And Trump-being even MORE stupid and ignorant-let him kill it
Norm Ornstein@normornstein.bsky.social · 7mo agoOf all the examples of people dying because somebody inexperienced was in charge, the biggest, most horrifying was Elon Musk and DOGE. No idea what AID did, didn’t care, blew it up and at least 600,000 people died unnecessarily as a consequence. Mass murder out of ignorance and bias. Thanks, Elon.
