Een bijzonder beeld vastgelegd door onze wildcam! 🦌 Deze reebok in de Nieuwkoopse Plassen had maar één geweistok, precies in het midden van zijn kop. Net een eenhoorn! Voor onze boswachter was dit ook een uniek gezicht. “Je denkt bijna dat het nep is.” 👀

Deze ontmoette ik gisteren. Serieus, het lichaam net zo groot als mijn hand, met uitgestrekte vingers. Toen ik probeerde 'm van het fietspad af de berm in te duwen viel 'ie omver, en toonde een onderlichaam vol met eieren.

Processing 100Tb of CSV files on a single machine is insane, little over 1hr per query, even if on a powerful AWS instance. Question heavily the need for complex systems when this is what’s possible now. Can’t wait for full write-up. Incredible work.

Bij het verkiezingsdebat zegt de VVD dat werken moet lonen. Gelukkig hebben we de rekenmeesters van het CPB nog..

Bij GroenLinks-PvdA gaan belastingen op inkomen/arbeid onder aan de streep met €5,1 miljard omlaag.

Bij de VVD met €3,3 miljard omhoog.

Bad news for the crowd that believes LLMs should get human rights for feigning consciousness (from "Mind Your Tone: Investigating How Prompt Politeness Affects LLM Accuracy", arxiv.org/pdf/2510.04950)

Fun fact: I worked on this technology back in 2010, here in the USA - a biomimetic adhesive for wet conditions, based on amino acid monomers. Less-fun fact: I, along with a hundred other researchers, was laid off from our large adhesives company because they wanted to "focus on core capabilities"

⚠️ Chinese researchers have invented bone glue that mimics how oysters stick to surfaces underwater.

The adhesive can reportedly repair orthopedic fractures in 2-3 minutes, even in blood-rich environments, and is bioabsorbable.

It's hard not to come back from biking in modern Europe (let alone the rest of life) without feeling like we're being cheated and robbed on an absolutely monumental scale in the US

Utah, took a sabbatical in France with my bike in spring and it was glorious. Back home and it's just so frustrating. Why can we have nice things too?!

Net in de keuken mijn bammetjes aan 't maken en "PLOF" tegen het raam.

Een blik naar buiten bevestigde het vermoeden: tussen de kliko's een roodborstje; op zijn rug; op wat snelle stuiptrekkingjes na roerloos.

Maar nu, een halfuur later is hij weer bij zn positieven. Op naar het volgende raam.

We published a new deep dive by Laurens Kuiper, who recently redesigned DuckDB's sort.

One data point: ordering the TPC-H SF100 lineitem table with the memory limit set to 30 GB is 3× faster in DuckDB v1.4 than in v1.3.

As web developer or product manager, you might want to play and test these APIs to see if they're any good to you.

That's what LLMdeling is for. It lets you play with these APIs, and test your own scenarios so you can figure out if you want to use them in your apps.

Microsoft on the other hand bases their implementation on their Phi4-mini model, without providing a clear moniker for these features You can enable these features in edge by navigating to edge://flags and searching for "Phi".

Google currently bases their implementation of these features on their own Gemini Nano model v3, and calls the browser APIs "Built-in AI". You can enable these features in chrome by navigating to chrome://flags/ and searching for "Gemini".

A quick breakdown of the APIs:

- Translation: APIs for natural language detection and translation
- Writing. APIs for generating, correcting and editing text content.
- Reading: The Summarizer reduces and/or extracts text content
- Generic Prompting
