In the same way there are kleptomaniacs that can't keep themselves from stealing stuff, I suffer from some form of debug-o-mania where I seem to subconsciously seek out life situations that make me spend time debugging in gdb or rr.

Meaning that infrastructure like AWS is not something that Signal, or almost anyone else, could afford to just “spin up.” Which is why nearly everyone that manages a real-time service–from Signal, to X, to Palantir, to Mastodon–rely at least in part on services provisioned by these companies. 8/

The French crown jewels stolen from the Louvre are steeped in history — and priceless. What happens when they make it to the black market?

Is There a Price Tag for the Louvre’s Stolen Jewels?
As soon as the gems hit the black market they could be much less valuable, and their historic value drops.

2/ Altho massive punitive damages jury award against NSO Group ($167m) got reduced by the court, as is expected in cases where it is so large (to 9x compensatory damages)... This is likely cold comfort to NSO since I think the injunction seriously dims value of NSO's spyware product.

Kinda wild to think the Berkshire's 350bn cash pile is likely in T-Bills, and that 350bn is almost 1% of the 37Tn in total US debt. Berkshire alone holds 1% of US debt.

The US Army in 1945 also noted that fascistic political figures would seek to whip up animosity toward disfavored groups like Black people, religious minorities, and the foreign born, creating "convenient scapegoats" to rile up their followers.

Kinda wild that the insignias of the iron front are now deemed "far left". I mean c'mon, the SPD was always center-left, the iron front was "centrists to protect the democratic constitution of Weimar against fascist takeover". That's not far left, that's "I want democracy".

The political discourse in the US will argue that "Bella Ciao" is a radically left-wing song. It's not, it's the song of everybody that opposed the fascists. Opposing fascism is not radical left-wing. JFYI.

Reality has a surprising amount of detail, and ... 1) it seems the Darda motors of my childhood where great and are still functional today, 40 years later. 2) The company sold itself to an international buyer and moved production to China in the early 2000s and quality went to shit. ...

We also know how to fix it. Unfortunately the fix is hands-on, individualized mentorship. That requires more teachers and more resources. It’s harder so teachers should be compensated better.

We know that we are doing assessment wrong. We do it because education is driven by the wrong incentives and bad regulations. Education is under-resourced, requiring larger classes that require scalable assessments.

In reaction to Netanyahu‘s latest Gaza plans Merz announces suspension of German weapons exports that could be used in Gaza. Merz also „urgently demands“ that Israeli government stops any steps toward annexing West Bank. Netanyahu only has himself to blame for this rupture.
