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.

OpenAI's Head of Strategic Futures, Dean Ball, has posted on X to complain about a Chinese company publishing an open AI. OpenAI thinks that open AI is a bad idea, and here are some arguments: "Open-weight models are inherently decelerationist [slowing down AI development], and ... in the end, open-weight models deter further AI capex." Good. Oh wait, you meant that as a bad thing? "One probable outcome of an open-weight-model-dominant world is full AI communism" What does that mean? "Rather than a market product, AI is a "public good" Oh, ok. But isn't a public good good for the public? "This future strikes me as a dystopian hellscape" A public good is a dystopian hellscape? 1/3

Team USA's top scorer, Balogun, received a red card in the game against Bosnia. Which means he would be suspended in the next game. President Trump called FIFA boss Infantino. Now FIFA states without further explanation that the suspension is lifted, and Balogun can play in the upcoming game against Belgium. Following that, Trump publicly thanked FIFA for that decision. If that would have happened 2018 in Russia, Putin interfering with the world cup, the explosion of the media would have been immense. But since it is the US and Trump, I guess all is fine?

But the ongoing indiscriminate onslaught of AI bots on everything with an URL is just actively killing the web and its open nature. Websites, which were meant for the few human visitors, get crawled at rapid speed, open REST APIs are being overrun, the few SPARQL points out there get slaughtered by queries, causing downtimes, cost, and what not, actively killing those parts of the Web which have historically just been happy to be there, with little maintenance, across the years. 2/5

The director-general of Germany's second largest public broadcaster has forbidden an artist to perform a song he was invited to for the 100th edition of a political comedy show, against the protest of the show runners. The name of the song: Keine Angst (can mean both, don't be afraid and no fear) by Danger Dan The song calls to stand up to fascism. The name of the director-general who forbid the recording? Himmler. https://youtu.be/Gg-SCpXba64?is=ElvvUHfpj5PadnBm #resist #fascism #dangerdan #censorship #freespeech #democracy

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.

@david_chisnall@infosec.exchange I doubt it'll make a difference. To the best of my understanding, every terms of use of LLM-based tools comes with such a disclaimer already. Every chat interface has such a warning. Probably every contract a company signs with Google explicates that risk already. That's not new, and I doubt it'll be cited.

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.

@ireneista @ami_angelwings They aren't. The God who punishes Eve is much closer to the God who killed almost all of humanity in the flood (and then regrets it) and who bombed Sodom, than to the much later God who's described as just and merciful. It's also the same God who banishes humanity from Paradise. Not as a punishment, the punishment is distinct, but because he's *afraid*/worried they'll eat from the Tree of Life and "become like us", as God says.

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).

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.
