Thanks you for coming all the way speaking! That makes sense.. I'll need to experiment a bit. So far I looked at stuff with pmap -x but I'm not sure that the reported metrics are the same as the accounting done by cgroups. For context we are playing with an experimental k8s truly-single-binary build and, as the binary (~100MB) is used as init, I was wondering what would be the impact on the pod cgroup https://forge.tedomum.net/acides/hepto

This makes me really happy.
Everyone at #FOSDEM is touting their "single binary", I guess what we need now is a binary dating site
Small question for @cdown : how is shared memory managed within cgroups? If I have a big executable (let's say 100MB, because cool kids like static these days) that is executed from different cgroups, is that memory accounted for in each cgroups? Are the pages cached globally by the kernel? Do each process have it's own cache?
And that's a wrap

I'm hyped for the next one, Chris Down is a good speaker and his cgroup talks are usually nice summaries for what is happening in the kernel

Why resolving two names in a GUI program is hard ;
A summary of available name resolution APIs on Linux and why a new one is needed by Petr Menšík
getaddrinfo is blocking. getdns and adns are DNS-specific. systemd-resolved is systemd.
GUI applications want to wait for events, not to have blocking calls.
First step to speed parsing: drop Lex and Yacc (too slow and too general for DNS zone file parsing).
Next step, preventing the CPU pipeline to stall (bubbles - NOP - stall the flow.)
