  I am slow in adopting all the shiny new technologies. (I actually went "backwards" to vim somewhat 10 years ago, after having been forced to work in one of those big IDE-things, eclipse I think it has been. Even emacs seemed bloated afterwords, though I had long years of happy relation with the latter. No hard feelings there.) Turns out that it's good I could not remember the name "openclawai" that has been recommended to me by a fascinated coding-per...

  Quickly, I have to absolutely urgently to help the chair of the board of GÉANT, who inexplicably unexplained cannot access his geant-email and thus has to borrow a presidents(! no less) gmail-account, with something utterly urgent! !k! Europe, no, the world is at the brink of cyber-apocalypsis. #scamoftheweek Is this some insufficient elaborate scam for busy professors? You are out of luck, I have grading work to attend to. There is no other task on my schedule for today — because I will use...

  Category Theory is cool and if only because you can abbreviate it as "Cat Theory". Started re-reading "Category Theory for the Sciences" by David Spivak with a friend. Read the foreword for the first time and immediately got this nice quote from it: “when we formalize our ideas, our understanding is clarified. [...] And if we are ever to get to the point that we can input our ideas into computers, we will need to formalize these ideas first.” Very much wha...

  Nice, short read on vulnerabilities in two password managers. (Others seemingly have not been addressed.) Weaknesses like "missing authentication" might raise some hairs. https://arstechnica.com/security/2026/02/password-managers-promise-that-they-cant-see-your-vaults-isnt-always-true/ Short commercial for the standard Unix password-manager https://www.passwordstore.org/ here. Main advantage in this context is that the actual software is simply combining trusted and tested t...

  It seems every military organisation has to do #stravaleaks at least once … These days it has been the french. Maybe we should provide strava with the Nobel Peaceprice. They seem to make military operations much more risky. Maybe this leads to (significantly) less war. https://www.lemonde.fr/international/article/2026/03/19/stravaleaks-le-porte-avions-charles-de-gaulle-localise-en-temps-reel-par-le-monde-grace-a-l-application-de-sport_6672445_3210.html

  Short: I had to rotate my OpenPGP-keys. The current key is now 63F831BAAAFEA6B63D9514E441D8FF5258F8FB4A Get it from the usual keyservers. Long: I am switching from GnuPG to sequoia-pgp and at the same time I had two expired subkeys. A ``sq key rotate`` did not produce the results I intended (new subkeys) and adding two new subkey did not seem to be importable to thhunderbird. The easy way out was to generate a completely new key — also as a test to see if this one could be imported into th...

  Let me borrow from Bruce Schneier @Schneier_rss: ‘We don’t issue letters of marque on the high seas anymore; we shouldn’t do it in cyberspace.’ [1] He has gotten struck by a sentence in the 2026 US Cyber Strategy (linked in [1]) which seems to imply that the White House (signed by DJT) is actually planning to somehow incentivize private companies to attack adversaries in the "cyberspace". (Sorry, I still cannot write the word "cyber" without flinching, I have...

  Wenn du mein Betriebssystem unter Kontrolle hast, wieso musst du mir das in einem PDF mitteilen? Ich fände es beeindruckender, wenn da einfach die klassische Erpressernachricht auf dem Bildschirm auftaucht. Ausserdem ist das PDF das du mir geschickt hast kaputt. ;-)
