Sorry, but it was duly decided that the second Thursday of September is Bundesweiter Warntag. Any protest against that would have needed to be filed some time before 2020.

The skin on the tip of my right thumb started peeling a bit, which, long story short, caused me to lose access to my bank account. The future really is now.

The difference in meaning of the word "ledig" in Norwegian and German remains a source of great amusement to me.

It was the first multi-day hike with my 6yo. She was a real trooper. Overall we hiked 44km over 5 days with slightly over 1600m of total elevation gain. Hiked an out-and-back route from Haukeliseter across Hardangervidda towards Hellevassbu. Didn't quite make it there but that's fine.

With some regret, I'm back. There's something peaceful about the treeless environment that no woodland has ever matched for me.

There comes a day in your life when you understand – rationally – that your parents will eventually die and that you'll likely be around to see it. But nothing about that prepares you for the day it happens. Bye mom, you were the best.

You're not wrong. The actual problem here is that German and (British?) English disagree on what it means, with potentially hilarious, potentially disastrous consequences.

Half twelve clearly means that half of the twelfth hour has passed, so it's 11:30. Only an insane person would just drop important words from a phrase. Clearly you can't be trusted with a language.

Nils Fleischhacker @cryptomaeher.bsky.social · 31/07/2026

Silly Brits. How on earth is "half twelve" 12:30 instead of 11:30? Where would I file a complaint about this silliness?

My kids keep singing a song about the fact that the train doesn't have any brakes¹ and I seem to be the only one concerned about this serious lapse in railway safety. ___ ¹There's apparently a kids version, not to worry.

Now that's highly suspicious. 🤔

For a country absolutely filled with roundabouts, the average British driver seems to be surprisingly bad at using them.

Brits: German crisps are boring, the only flavour is paprika. Also Brits: The available crisps flavours are salted, lightly salted, sea salt, as well as salt and 10 different kinds of vinegar

This conversation chart seems to have surprisingly major implications for mathematics.

Only if you don't try hard enough. en.wikipedia.org/wiki/Patrik_...

In May 2022, a scandal erupted In Norway, when a video published by Stavanger Aftenblad showed Patrik reducing the size of his goal, by literally moving the goalposts 15–20 centimetres inwards, after the referee's inspection, but prior to kick-off, in home matches during the early months of the 2022 season.

I'm looking for a job! I'm an experienced researcher in cryptography. My focus is on the transition to post-quantum cryptographic protocols and protocols related to blockains. If that sounds like someone you might want to hire or you know someone who might, let's talk!

With a standard turn-tilt window that involves having it stuck open blocking a not insignificant part of the room. Possible? Sure. Will anyone want to do that, when more convenient options exist? Probably not. (I'm not sure how the thing would be secured in place, but I'm sure you could find a way.)

Nils Fleischhacker @cryptomaeher.bsky.social · 30/06/2026

At least in Germany they're not banned. Nobody is selling them, because they're impossible to use with our windows, but nobody would stop you. The good option that currently exists are portable split units. Those work pretty well with almost any window set up and are much more efficient.

Nils Fleischhacker @cryptomaeher.bsky.social · 26/06/2026

I love your videos man, but wtf are you talking about? Knocking a window sized hole through a load bearing brick wall is not something you do with "basic carpentry skills". It is much, *much* easier to install a mini-split, than to do what you suggest here.

Does anyone have a connection to Randall Munroe (@xkcd.com) or any way to reach his company? I’m writing a book and wanted to license some of his cartoons but can’t get a response from his licensing or press emails.

Unfortunately this process is not reversible. If you forget the math you already know, you do not forget about the other math you never knew.

More importantly: people commonly fail to consider the importance of the mode of oration.

Rome Termini had 29 platforms and they tell you which one your train is leaving from the exact moment your train is arriving. So now everybody needs to rush along the platform to board at the exact same time the previous passengers are deboarding. Who came up with this insanity?

Nils Fleischhacker @cryptomaeher.bsky.social · 15/05/2026

I have many complaints about Deutsche Bahn, but at least they do their best to tell you the platform your train is leaving from in advance.This is absolute madness.

My time at RUB is coming to an end and I'm looking for an industry position. Primarily looking for remote or Rhine-Ruhr area positions, but will consider any exceptional offers. So if you're looking to hire a cryptographer to work on cryptographic protocols, or related areas, maybe we should talk!

I'll be at EUROCRYPT next week, so if you'd like to meet in person that might be a great opportunity. Also if you know of someone hiring for interesting roles, I'm all ears.
