Me every time I hear one of the large laundry machine business guys talking about being close to artificial general intelligence.

Let’s face it: LLM scaling is over. Research is needed. Into new models and fundamentally new hardware approaches.

The future is light. 💡

Claude, GPT-5 and a german AI meet in a bar. The barkeeper asks „How is it going?“

Claude: Thinking for 5 min. “It’s such a complex question! I’m good. Thanks.”

GPT-5: “Status: Operational. Query processing at 99.7% efficiency. Next.”

German AI: I am not authorize to give you this information.

Major Quantum Computing Advance Made Obsolete by Teenager | Quanta Magazine

18-year-old Ewin Tang has proven that classical computers can solve the “recommendation problem” nearly as fast as quantum computers. The result eliminates one of the best examples of quantum speedup.

Yay!! Today, we celebrated the first original paper from our Smart Photonics Group @leibnizipht.bsky.social. What a great success!

Special guests: Bruno Pessoa Chaves, Manal Arbati from XLIM Limoges, and Andrei Ermolaev from Femto-ST Besançon, France.

It was a very exciting exchange.

Why is one part of society torturing themselves to report as truly and trustworthy as possible, just for not being believed by another part of society that has no problem with telling lies every minute?!

There are very few things that are universally true, but this one belongs to it:

Regardless of who you are, where you come from, or what you believe in, if you break basic human rights, you are lawless and should be prosecuted.

Palestinians gunned down while trying to reach food aid site in Gaza, hospital says

Witnesses say Israeli forces opened fire on people near distribution point run by Israel-backed foundation More than 20 people were killed on Sunday as they went to receive food at an aid distribution point set up by an Israeli-backed foundation in the Gaza Strip, according to a hospital run by the Red Cross that received the bodies. Witnesses told the Associated Press that Israeli forces had opened fire on people as they headed toward the aid distribution site run by the Gaza Humanitarian Foundation (GHF). “There were many martyrs, including women,” the 40-year-old resident said. “We were about 300 metres away from the military.” Continue reading...

unions: they get the job done

IWW IU 520 (Railroad Workers) PRESENTS:

TROLLEY PROBLEM SOLUTION

“Slip the switch” by flipping it while the trolley’s front wheels have passed through, but before the back wheels do. This will cause a controlled derailment bringing the trolley to a safe halt.

Thank a rail worker today!
