Just an observation: my experience flying low-cost in Europe has been approximately constant for 10 years. A similar statement is true about trains and buses. The same is *not* true about cars.

You think we already have enough entropies and divergence measures? I don't think so!
In our latest work (arxiv.org/abs/2509.20472), we introduce yet another information theoretic measure -- the computational relative entropy.
Let's have a quick rundown👇

For all the interest in combating climate change you see around Germany, I wonder how many tonnes of CO2 can be traced back to the poor service offered by @bahn.de @bahn.bsky.social. How many people choose to fly or drive a car just to avoid ICE delays and short-notice cancellations.

True or false? The instant the train crew changed from SBB 🇨🇭 to DB 🇩🇪 a 20' delay materialized out of thin air.

Listen, Broligarchy is not some cute synonym for oligarchy. It's genuinely different & WAY more dangerous.

There’s a sort of Trump apologist, a relatively small but loud subset, who probably don’t realize or intend to be, but are so attached to a previous hyperbolic claim that they deny anything important changed.

Is there a particular reason why authors of published #ML papers don't update the doi on arxiv? I usually find a comment "paper published in XYZ", but right underneath it rads "cite as: arXiv:XYZ". This is not true for papers in quant-ph, for example.
