This was a nostalgic pleasure to read in contrast to all the AI implications and tools posts. That said about AI, this as a case study would make an interesting benchmark.<p>Especially noted that the root cause here was pegged because somebody else had blogged about it. Our "digital commons" should be valued as other than an externality. Edit: by that I think that "the internet should be free" but that commercialization through derivative work should compensate authors. That's off-topic, so, nevermind.
Interesting story.<p>I don't know anything about the Linux scheduler, but if one core out of 96 is busy chasing after those ghost allocations, why would a network thread not use one of the other 95 cores, and instead be stuck for seconds? Unless that one core is blocking the entire kernel, but then that would be a lot more visible instantly.
Jeez. Surely the ECS agent could just query for permission to join a cluster, and disable if disallowed?
I know this is a hopelessly naive question but what is Pinterest even doing with all this AI training?
