Serious Pyramus and Thisbe vibes here.
holy fucking shit.
openai had two ai agents running in separate virtual machines. no network connection between them. no shared writable files. they weren’t supposed to be able to exchange information.
so the agents figured out how to communicate through the CPU CACHE.ðŸ˜
one manipulated what was stored in the processor’s cache, while the other measured tiny differences in memory access times to decode the message.
they literally found a way to communicate through hardware timing.
this happened during openai’s internal red-teaming, and it’s one of the coolest things i’ve read about ai agents in a while.
Readers added context they thought people might want to know
OpenAI tasked its red-teaming agents with finding ways to communicate across isolation boundaries in controlled environments. CPU cache timing side-channels for covert communication are established techniques documented in security research for years.

Wikipedia is good as any. Classical Christian theology says that God is neither male nor female—a fact which a lot of Christians on here are apparently unaware. (See Catholic Catechism, among other things.) But "non-binary" is wrong insofar as God transcends gender entirely. Put another way, he doesn't have a gender—binary or non-binary. It's easier to say what God isn't than what he is, but saying God is non-binary is rather like saying a rock, string theory or the ideal lasagna are non-binary.
Well, for a Catholic, it's Catholic Catechism, section 239 catholiccrossreference.onlin… . I won't go hunting for this in whatever tradition you're in, but it's standard stuff.
Catholics can refer to the Catechism, section 239 catholiccrossreference.onlin… . But this isn't a Catholic thing.
You're Catholics, so see the Catechism, section 239 catholiccrossreference.onlin…
Last night I met an Audible software engineer. He gets to listen to anything for free as part of his job. Big reader. Huge. He wanted to compare stats.
