My Unix Archive mirror was slaughtered by LLMs overnight, it is on a 10G link, they were taking over 1Gbps in requests to the same files over and over again.

This is ridiculous.

The attempts by law enforcement & governments to subvert end-to-end encryption are ongoing. The European Commission is going to spend a year thinking about their new "Roadmap for law enforcement access to data", and they are (genuinely) asking for people to join their expert group to help. Here I urge you to join that group (also because I can't): https://berthub.eu/articles/posts/possible-end-to-end-to-end-come-help/

#campplusplus this year is, again, fabulous. Highly recommended to attend.

Funny FPU trick I discovered yesterday to detect arm64 or x86_64 architecture at runtime

There was recently an article about using salvaged Sun Ray thin clients with a modern server. @bcantrill's response to that article on Hacker News mentioned his story about using DTrace to debug a performance problem on a Sun Ray server. He linked to a paper he wrote for Usenix, but I prefer his extended telling in this 2007 talk: https://www.youtube.com/watch?v=TgmA48fILq8&t=35m6s
