Zen quote of the day.

When you go to the lavatory, spend a longer time there than is necessary.

Communist Poland was exceptionally good at making fun of secret police and egomaniacal leaders.

If my American friends need some good authoritarian jokes so that they can keep their spirits up for the long run I can suggest some!

In case anyone here has connections with the Python team: can you please tell them to update their docs on XML security? The way it is is quite misleading, and it's been annoying me for a while. I raised this a while ago in their issue tracker, but it got no reaction whatsoever. https://github.com/python/cpython/issues/127502 🧵

PHP just turned 30! 🎉 Did you create guestbooks for your website like the early users of the language? 📜 Do you remember technologies like PHP-Nuke, phpBB, or browsing vBulletin forums? 💻

another day, another binary file format with a badly designed magic number

not gonna call it out specifically but here are some RFC2113 MUSTs for magic number design:

MUST be the very first N bytes in the file
MUST be at least four bytes long, eight is better
MUST include at least one byte with the high bit set
MUST include a byte sequence that is invalid UTF-8
SHOULD include a zero byte, but you can usually get away with having that be part of the overall version number that immediately follows the magic number (did I mention that you really SHOULD put an overall version number right after the magic number, unless you know and have documented exactly why it's not necessary, e.g. PNG?)

good examples:

• PNG
• ELF

bad examples:

• GIF
• PE
• PDF

End of an era: our CVSweb service turned 21 today, and was promptly retired. Our anoncvs was similarly shut down at the age of 21 two years ago, quietly.

Alan Turing died by suicide on 7 June 1954. Turing was convicted of gross indecency in 1952 and given a choice between imprisonment and probation. His probation would be conditional on his agreement to undergo hormonal physical changes designed to reduce his libido. Turing's conviction led to the removal of his security clearance and barred him from continuing with his consultancy for GCHQ. He was denied entry into the United States after his conviction.
