Das erinnert mich sehr an die Arbeiten von Andy Goldsworthy!

When I met Hermann Härtig at Eurosys 2006 I talked to him about the relevance of formal verification in OS design and he just smiled and asked me if I can show that a user space program can’t escape to ring 0 (kernel mode) on the CPU. 😲

Counterpoint: imagine an alternative world where the NSA truly believes that QC is possible within two or three decades. Could we observe the difference from the outside? And if no, which world is more likely?

I haven’t been in Paris for a long time. But I have been in Barcelona and although it is smelly and really crowded, I had no involuntary body contact there at all. People seemed to in general have more awareness of what is going on around them. Japan is wonderful, and a great inspiration!

Inside the train: People blocking free seats, playing loud music, talking loudly, drinking beer, coffee in a puddle on the ground. I’m used to it (I’ve grown up here), but it’s just flat out awful. I think the trains would be better with a more open seat layout and strict, enforced no food/drinks).

And because trains share platforms, there are no markings to tell you where the train goes and where you can stand and wait. People rush to the doors and block the people trying to get out - it’s really annoying.

By far the biggest problem is the trains, though. It’s nice that we have such a dense public transport system, but they all share the same rails, which causes congestion with famous delays. And if you miss one train, you have to switch platforms with all your stuff. Platforms can also change sudden.

Let’s not talk about the dirty ground. The Germans in my area are in general pretty badly behaved (shoving, running, letting your wheeled suitcase run ahead of you without holding it, taking loudly etc.) and there is just not enough workers around to keep things clean and people in check.

It’s also insane that renting a little trolley for your bags costs 2.50 EUR. And of course you can’t go to the train station with it, so it is pretty useless anyway.

Double it and give it to the next person.

At least we can still sit on a Cray-1. Today’s invisible infrastructure will end up being scrapped in the blink of an eye.

It would be super useful to have Claude ingest a paper and try to reproduce (some of) the results. I tried it once and it completely failed to get the point.

My favorite part is that it requires very long hash functions. 😅 one author is on Bluesky btw, shoutout to @tiborj.bsky.social

That’s going to be your first and half of your last slide, right?

It’s a quote attributed to William Faulkner: „In writing, you must kill all your darlings.“ I find I have to remove about half of what I initially include in a text, sometimes more, to make room for the essence to shine. ✨

Kill your darlings.
