@waldi @Ramonsta72 Ja klar, sowas ist auch oft… Die Reaktion ist immer sehr situativ.

Wenn ich wem Geld geb, dann auch ohne Strings attached…

Ich reagier eher empfindlich, wenn ich gerade selber irgendwas in einer Tasche suche / krame, das find ich dann sehr übergriflich.

Mir geht seit Samstag folgendes Erlebnis nicht aus dem Kopf: Schwimmbad mit Kind -> Burgerladen. Draußen ein Obdachloser, der fragt, ob ich ihm was zu essen kaufen könne. Sicher, warum nicht.

Es dauert lange, voller Laden. Mensch wird anscheinend von innen beäugt, ich dann auch, als ich ihm das Menü bringe.

Kind erzählt mir vom Nachbartisch: "Jetzt hat der dem echt was zu essen gekauft und der hängt jetzt da ab…"

Deutschland, Du kannst so hässlich sein. Hauptsache, der Wal hat nen Namen.

Ich den Punkt noch ergänzt, Du hast absolut recht.

Im Grunde ist es die Fortsetzung der Dopamin-Abhängigkeit, die wir auch in fast allen anderen System gerade sehen.

@s2b I guess that's hard call, without kidding. These people are for weeks / months "alone" from home. I would think 100% restrictions would be detrimental towards keeping a functional environment up.

@s2b As a recovering Strava addict, it never ceases to amaze me. The privacy controls are not that hard to enable… Maybe one need more than half a brain cell to realize setting a home zone of 500 meter doesn't do it on a moving aircraft carrier, but what would I know about that?

Kicker at the end, after spitting all the hard facts.

> It is an equally well-established fact that the best response to the universe's sense of humour is a stiff drink, a comfortable chair, and the quiet confidence that eventually, even the universe runs out of material.

Best read in a while.

> They were lying by a factor of two, which, in the context of ballistic missile capabilities, constitutes what experts call “a very bad surprise”. Rome, Paris, and London are now within the theoretical strike envelope. The British gave permission for Diego Garcia to be used for strikes against Iran and discovered that the Iranian response could, if Tehran felt creative, arrive at Heathrow.

The thought that #Anthropic or #OpenAI won’t squeeze out the maximum possible margin from their services and products the same way #Broadcom is doing it now with #VMWare services and products is pretty absurd. Its impact though will be much, much higher. #AI #AIDict

Today I'll be upgrading a couple of things to #DuckDB 1.5 and yet again, the folks at @duckdb provide a perfect way to adapt to a breaking change, here getting the order of x/y right:

- in 1.5 you can set geometry_always_xy = true to have xy in lat/long order, otherwise you get a warning
- in 2.0 not setting it, you get an error, but you can ofc use false to get <= 1.5 default behaviour
- in 2.1 make the new one the default

They did the same in 1.3 for lambda style.

Next case of saying the quiet part out load…

https://newrepublic.com/post/207693/palantir-ceo-karp-disrupting-democratic-power

> Palantir CEO Alex Karp thinks his AI technology will lessen the power of “highly educated, often female voters, who vote mostly Democrat” while increasing the power of working-class men.

So nice, bashing women and pretending he has anything remotely in common with working class.

They’re saying the quiet part out loud now.

Scott Shambaugh—one of the authors of matplotlib—got hold of the "soul.md" file that the "operator" of the "autonomous scientific coder" wrote for his #OpenClaw instance

https://theshamblog.com/an-ai-agent-wrote-a-hit-piece-on-me-part-4/

As I guessed last week already, encodified, toxic and fragile masculinity. Disgusting. Imaging such a person on your team.

Probably Scott has better things todo, but I sent him a message a couple of days ago in support.

Let that sink in. Even one of the loud and vocal AI proponents such as @simon admits

“I no longer have a firm mental model of what they can do and how they work, which means each additional feature becomes harder to reason about, eventually leading me to lose the ability to make confident decisions about where to go next.”

https://simonwillison.net/2026/Feb/15/cognitive-debt/

Not afraid of many things AI can inflict on my life, but I’m personally very much afraid of acquired helplessness such as this.

#Belgium #Flanders tourism agency, you’re the best. Last year I did a bunch of their “Iconic cycling routes”, send them a bunch of my pictures and this week, I received in return hand signed certificates.

Even nicer than the cobble stone I got for the Flandrien challenge.
