I was expected the answer to "why is Codex so much slower than Claude Code" to be something related to their models, and maybe it is, but it surely is not helping that Codex runs all the tool calls under x86 emulation.

In Ubuntu 24.04 "perf top" now requires selecting which PMU type to monitor (P and E core types), and will then only list that one. This is an extremely crippling regression for me. Any idea how to get rid of it? Is this a regression in the kernel itself?

Ubuntu 24.04 wrecked my LVM+LUKS install upon upgrading from 22.04. After a few days of fighting with it, key tricks were to add "initramfs" flags for all LVM drives to the crypttab and finally "keyscript=decrypt_keyctl" to avoid having the reenter the password. All of this just worked in 22.04 🤷

The reactions to this blunder remind me of the people who looked at computer blunders and concluded "computers can't play chess", e.g. timkr.home.xs4all.nl/chess2/honor... It's not because the computer makes a blunder that an 1800 Elo player would avoid, that the computer is <1800 Elo.

Recently in TIME Magazine, in a summary titled "A history of interactivity", Kasparov's 1997 defeat by Deep Blue was named alongside events like the Gutenberg Bible, the first photograph, the first sound movie, and the invention of the World Wide Web. In the chess world, we should know better.
