Today, for the first time, a mother in the hospital told her, "No thanks, we'll just get ChatGPT to do the nicer photos."

My wife is a photographer. Her business is photos of newborn babies. Relatively simple ones taken at the hospital right after the baby is born are the hook to get people to sign up for more expensive sessions at home in the first few weeks: different outfits and settings, "adorable" is the goal.

An unidentified man dressed in a Batman costume angrily confronted Santa Clara city officials during a joint meeting of the City Council, city authorities, and the Santa Clara Stadium Authority on Monday, using his public comment to condemn the city’s stance on cooperation with ICE.

I dreamed I was at a dinner theater with white tablecloths, and Dolly Parton was going table to table, wearing white lingerie and doing a burlesque bit with a 1kg plastic package of miso.

This is terrifically sad news. One of the true giants of the historical profession, endlessly curious and creative, and a genuine pioneer of new kinds of international history, especially using NGOs and culture as topics/methodology.

Other numbers around the web indeed suggest several times that. Of course match to match variability will be high.

But there is no way that I burn 2,500 calories sitting on my butt and Serena only burned 500 more in a high intensity match.

Best qTanner codes (table)

Started to curate a table of small quantum Tanner codes.
If you want to play with codes with fairly good parameters, all the parity-check matrices are available.

How far do you run during a tennis match? - BBC Bitesize At Wimbldeon 2019, the pros like Serena Williams will be covering quite long distances when they play.

These numbers seem like a serious underestimate in both distance and calories. I might believe them per set.

Yeah, endurance is a huge factor for them. Also, slapping a ball hard enough to leave Wile E. Coyote-like holes in you, accurately enough that they can pick which kidney, all done at full sprint.

Jupiter's moon Europa, with an inset that shows a magnified view of one part of its surface. The inset photo shows grooves and cracks on Europa's icy surface. Overlaid on the photo are areas marked in purple what show non-detections of ammonia, and four small areas marked in red that shod where ammonia was detected.

Would you really like to live in a society where you have no responsibility and no freedom, no choice, only the false option of obedience to the law, or disobedience followed by punishment? Would you really want to go live in a prison?

Screenshot of an X.com post by The Associated Press (@AP) stating that dozens of immigrant families protested for better treatment behind fences at a Texas detention facility, where a 5-year-old Ecuadorian boy and his father were sent after being detained in Minnesota. Below is a video thumbnail showing a crowd gathered outdoors along a fenced walkway; many people wear bright blue or red outerwear, and some hold signs.

After being held in two of them as a boy, I fought for decades urging America to never again build concentration camps and put human beings in them. It breaks my heart to watch this happen twice now in my own lifetime.

A bird's-eye view of a former Auschwitz II-Birkenau camp showing a wide dirt pathway flanked by parallel rows of barbed-wire fences. Groups of visitors walk along the path, surrounded by the remnants of brick structures and barracks, now reduced to foundations. Green grass contrasts with the somber history of the site, as the path leads toward a guard tower in the distance.

Auschwitz was at the end of a process. We must remember that it did not start from gas chambers.

This hatred gradually developed: from ideas, words, stereotypes & prejudice through legal exclusion, dehumanization & escalating violence... to systematic and industrial murder.

Auschwitz took time.
