The technical bar for EMs at Meta is quite high.

"The policy document attained by TechCrunch shows Facebook plans to take up to a 30 percent cut of subscription revenue minus fees, compared to 5 percent by Patreon, 30 percent by YouTube, which covers fees and 50 percent by Twitch."

Looks on par with other providers.

It's not as strong as the kernel. Go does not break APIs but may break undocumented behavior.

New comment by andrestc in "Using cgroups to limit I/O"

Author here.

>Also, while this article is quite rosy-eyed about cgroupv2, there are many many issues that mean that cgroupv2 is not really usable by container runtimes today -- despite what systemd might be trying to do with their "hybrid mode". A friend of mine from the LXC community gave a talk about the wide variety of issues that occur due to cgroupv2's weirdly restrictive API[3]. The blkio writeback cache limits are very useful, but they're really not worth the pain of breaking how container runtimes have to work.

I knew there are some problems with cgroup v2 but haven't quite looked into it. I'm going to watch the talk and probably add a note about that. Thanks!

>You can mount a single cgroupv1 hierarchy with multiple controllers attached to it (that's what 'cpu,cpuset' are), which then could (in principle) know about it each other. But they don't, since a lot of the cgroupv2 code is locked behind cgroup_on_dfl(...) checks. That's interesting, I didn't know about that! I'll add a note to the post.

Nice writeup. Interesting enough, SIGKILL does not work from inside the container: https://andrestc.com/post/killing-container-inside/.
