Hi all. Before our rapid rollercoaster descent into the economic abyss (?) let me remind you that not all computer science tools are AI, and many of them don't cost much to be useful. So please don't give up hope.
Now buckle up and enjoy the ride. 🥴

Now some think it's just about pivoting to OpenAI or Bezos' new "Prometheus" "AI" & I'm definitely no stocks guy, but it seems… odd to stop betting on foundational tech which has shown continual profit & move to app developers which a) Use said tech, b) have, to date, not profited, or c) don't exist
Softbank sold all it's Nvidia stock (www.cnbc.com/2025/11/11/s...)
Michael Burry of The Big Short fame's stock portfolio is now ONLY short positions in Nvidia & Palantir (www.ft.com/content/7fe1...)
Peter Thiel sold all his Nvidia stock (& 76% of his Tesla, but that's just deliciously petty) (👇🏾)

Prime Minister Dick Schoof called fresh elections following the first collapse of his government, which would go on to fall a second time within a few months.
The Netherlands is trying to draw a line under a year of chaos with fresh elections – will it work?

The one post I could find on Blue Sky about Selma van der Perre.
She visited the Dutch school in London every year to share her incredible story and meet the children. Her last visit was only a few weeks ago.
May she rest in peace. ❤️

Morgen jährt sich die Befreiung von Auschwitz. Ein ehrliches Gedenken beinhaltet auch den Blick auf Auslassungen im Erinnern. Jüdischer Widerstand gehört dazu & deshalb heute ein Buchtipp von mir. Rezi im Blog:

Citing the worrying poll, but not the papers debunking it. Perhaps a wrong choice?
Support for vaccinating kids against infectious diseases dropped from 81% in 1991 to 51% last year
