As the world hurtles towards geopolitical crisis, my marine biologist son sends photo of an underwater leaf slug from Fiji to wish us calm.

Very nice tool to test this! For a few original texts (that just live on my private devices and has never been uploaded anywhere) I could not get the de-BLANK-ing to work at all though... Maybe my excerpts where just too short or special-domain...

Coming soon to all of Europe?

I hope so. I've been complaining about our lack of autonomy in the domain for as long as I've been using Linux.

More than 200,000 Danish citizens have signed a petition to buy California as a response to Trump’s attempt to take Greenland.

They say they will provide Californians with β€œrule of law, universal health care, fact-based politics, and a lifetime supply of Danish pastries.”

Comment from Germany (where all of this might be different) β€” but is there a chance that these differences arise from how close each generation lives to other relatives like grandparents/uncles&aunts/…?

Maybe boomer care time is lower because grandparents where closer to help out more?

Globally, no single day in 2025 was cooler than its 1991-2020 average.

The numbers in this overview were pretty surprising to me - I wonder how they look for Germany... (were we also suffer from low economic mobility etc...)

Interesting work on LLM memorization:

Researchers were able to extract long book passages verbatim from Claude, Gemini and Grok --- sometimes almost the whole book.

Curious to see how this type of result influences Copyright cases...

Since Jan 1 2025, which feels like four trillion years ago, research has been shared on here 5 million whole-ass times. Bluesky recently passed 2 billion posts IN TOTAL.

So 0.25% of the entire site's traffic was citations to research.

That is actually massively high. Is it? Yes. Here's why.

I have been asked several times how we draw the 3D Figures for of our papers, so I wrote a blog post on it. This does not replace a Blender tutorial, just a couple specifics for scientific papers:

- import images as planes
- render edges
- transparent BG

lol. Before Stackoverflow I knew SelfHTML and R-Help. Stackoverflow et al. were so welcoming and well-designed by comparison (e.g., they would search existing posts based on the text you wrote). Meanwhile, all my current LLM prompts include stuff like "please please tell me when my premise is false"

To include some numbers here, StackOverflow in Dec 2025 had 3862 new questions. The last time SO had this few questions was in *Aug 2008*, the first full month that SO was in operations!

In its peak month (March 2014), SO had 207,493 new questions!

Because international media largely seems to struggle to choose the correct wording to describe what’s happening: the US, under the self describes β€žpeace presidentβ€œ, attacked another country and kidnapped its president. That is factual, no matter how bad or illegitimate Maduroβ€˜s rule is (very bad).

One thing I wrote about here is how technology has made buses *way* more convenient while techno-futurists were obsessed with flying taxis and self-driving cars.

Warum brauchts Journalismus von Netzpolitik.org? Nur so erfΓ€hrt die Γ–ffentlichkeit von Datenleaks und problematischen Entwicklungen in Richtung Überwachungsstaat (Palantir, Chatkontrolle..).

Digitale Zukunft geht nicht ohne unabhΓ€nge Medien, die sich auskennen! Also, wer kann: Jetzt spenden!

not a single query estimate, but just saw this paper from 2 days ago in my feed. The attached thread also puts it in perspective a bit..

Thanks, good to know it comes from OpenAI directly. I am afraid they have an interest to downplay this number so I would take it with a grain of salt.. the article puts it in context nicely, saying that its unclear what an average query is and how to account for the huuuge initial training costs

Where is the estimate from? I have been looking for a good source for this for a long long while....

Oliver Sacks Put Himself Into His Case Studies. What Was the Cost? The scientist was famous for linking healing with storytelling. Sometimes that meant reshaping patients’ reality.

Incredible piece on Oliver Sacks. If you were ever awed at his supposedly true stories (I remember being stunned by the account of the autistic twins who rattled off large prime numbers), read this. He told wonderful stories, but they were in large part fiction.
