If you have the Facebook app on your phone, Mark Zuckerberg would like to monitor your entire life by uploading every photo you take to a secret Facebook database and have AI identify every place you have been, every person you have met, every activity you have participated in, etc.

I do not know how Facebook lures people into turning this on, but I recommend everyone check their settings, and I have made these four pictures which show how you turn it off.

Please reply if yours was on.

I'm happy to announce the 19th release of the #OpenBSD #webzine

Der Vortrag von @sizeofvoid zu den Grundsätzen und (#Security-)Prinzipien von #OpenBSD auf den #CLT2026 war ganz hervorragend. 👍

Selbst ohne BSD-Kenntnisse gut verständlich! Klare Guck-Empfehlung, gerade in Zeiten von AI-Slop und Security-Desastern, die inzwischen teilweise wie Naturkatastrophen behandelt werden.

New #blog post alert!

I muse about research some of my grad students and I did around independently evaluating some #OpenBSD anti-ROP mitigations, and I bid farewell to being an OpenBSD developer.
