The banality of evil: in Cambridge, Maryland, a woman had construction workers work on her roof for several days, and then called ICE on them to get them detained, and avoid paying $10,000 for the work.

While Wikimedia content is free, the infrastructure that serves it is not.
Thanks to improvements in bot detection, more than *2 billion* requests per day get currently blocked, which would have otherwise caused further strain on the infrastructure.
The recording of my @iswc_conf@mastodon.social keynote is available online:
Wikipedia and the Semantic Web -- 20 years of co-development, and the future
Drawing on the roots of @wikipedia@wikis.world and the Semantic Web, how they influenced each other during the last two decades, leading to
@wikidata@wikis.world and peeking forward to @wikifunctions@wikis.world and Abstract Wikipedia.

Reading the Artemis II article on Wikipedia, I noticed the Wikipedia BabyGlobe spinning in space on the side.
Wonderful!
No human in my lifetime has been as far away from Earth as the Artemis II astronauts are right now. No one since Apollo 17 in 1972.
They are right now in an orbit that takes them up to 74,000 km high. In comparison, the ISS is in an orbit 400 km high.
Once this phase is over, their trip leaving Earth orbit and traveling to the Moon starts.
I'm imagining Rowan Atkinson dressed as a priest telling this joke and then explaining why the suffering inflicted on Jesus was necessary and right.

Wieder mal Neues vom Ballaballa-Balkan gehört, Folge 98 zu Mileva Marić, der ersten Frau Einsteins. Da hieß es, dass es in der kroatischen Wikipedia noch keinen Artikel zu ihr gab. Immerhin das Mal geändert. Den Artikel geschrieben während ich in der ältesten Buchhandlung der Welt sitze, weil mein Flug wegen dem Lufthansastreik verschoben ist.

Additions with unique digits: A tale of puzzling and AI
The other day, Markus Krötzsch and I were catching up when one of his kids came in. She told us about a puzzle her math teacher gave her:
How many integer sums are there where the equation uses each digit at most once?
The simplest example is 1+2=3, but 12+47=59 also works. On the other hand, 1+9=10 isn’t a solution because the digit ‘1’ appears twice (in the first number and the sum).
1/19
The letter E appears 5,173,357,556 times in English Wikipedia.
On the latest episode of "Between the Brackets", Yaron Koren hosts me for a chat about Wikifunctions, Abstract Wikipedia, Wikidata, AI, and much more. I hope you enjoy the episode. Thank you, Yaron, for hosting!

I finished reading a novel, Playground, by Richard Powers. It came recommended by Markus Krötzsch. I have to admit I rarely read novels, and this one was a good one to make an exception.
Ian Horrocks gives a great talk on the history of ontology languages around OWL in the last 20+ years, where we are now, the progress we have made. I especially enjoyed the QnA, and the slide on scalability progress, far faster than Moore's law would have predicted (and a testament to the results of researchers and developers in that area).
I especially liked the insight that it was far more important to come up with a standard than what exactly that standard is.
Livraria Bertrand in Lisbon, founded in 1732, is certified by Guinness to be the oldest, continually running book store in the world.
A quick search reveals: Osiander, founded 1596 in Tübingen. Korn und Berg 1531 in Nürnberg. Beck'sche in Vienna 1724 (but closed since 2018?), Höllrigl 1598 in Salzburg, Orell Füssli 1519 in Zürich, Cambridge University Press (and store?) 1534.
Now some of these started as print shops, but often also sold books. Anyone know a text discussing Guinness decision?
"A rose by any other name would smell as sweet" -- not in a world of LLMs, though, because whenever you fine tune the LLM to your task, you have to always consider what it has already learned in the initial pre-training.
