Yes indeed. Well done, MIT. All of our universities should have been reacting in this manner to all of the Trump administration's illegal overreach (looking at you, Columbia).

MIT's response to the Trump admin's proposed "compact" is excellent and should be a model for other universities. orgchart.mit.edu/letters/rega...

Ever seen a verbose render how a very small GC operation looks like in the context of larger safepoint? Here it is: (I need to blog about things you can see there)

as a girl with a PhD in natural language processing and machine learning it's actually offensive to me when you say "we don't know how LLMs work so they might be conscious"

I didn't spend 10 years in mines of academia to be told ignorance is morally equal knowledge.

We know exactly how LLMs work.

I'm surprised that there wasn't more noise around the license change of #Liquibase from Apache License 2.0 to Functional Source License (FSL) in Liquibase 5.0.0.

Using narrowband filters (Baader Solar Continuum 7.5nm in this case) does improve Moon contrast quite a bit, even though it pushes the exposure times way up. A doublet with heavy chromatic aberration gets fairly monochromatic light :P [Downsampled 4x here for preview:]

Ce soir à 12:00 le réacteur belge Tihange 1 sera mis à l’arrêt. Celui de Doel 2 suivra le 1er décembre. En l’espace de 5 ans la Belgique a donc perdu 3.8GW de capacité bas-carbone, malgré une population à 73% favorable à l’utilisation du nucléaire pour la production d’électricité.

Hehe!

That said, I wish that Swing was easier in many more cases. Sometimes it’s just way to hard to achieve something that would be a breeze in other UI systems.

It’s never too late, this submitted JEP (openjdk.org/jeps/8368874) just landed, it’s about adding a date picker in #Swing (preview). Using the `java.time.*` types.

TIL: In #Java, List.subList() and List.reversed() are implemented smartly. You may call these methods as many times as you want and in any order, but you don't get a long chain of references which leads to StackOverflowError. The longest chain of views is two: reversed -> subList -> original list.

But in the JDK, and with possible JVM support.

Just read an estimation of when JDK’s Stable Values could be final, JDK 28 **at the earliest**.

Nice engineering blog post on some query filtering at scale. There are some lessons in there.

They used a "bloofi " multidimensional bloom filters.
