Looking forward to get acquainted with Munich over the next two weeks. Might even make a return to OTB chess 👀

"the president defied a Supreme Court ruling to return a man mistakenly sent to a gulag... and spoke of sending Americans to foreign concentration camps.
This is the beginning of an American policy of state terror, and it has to be identified as such to be stopped"

I spent almost 2 hours painstakingly copying the orbits of all 128 Saturnian moons from the announcement MPEC and reformatting them for visualization...

Behold, here are the orbits of ALL 128 MOONS OF SATURN. This isn't just a moon system—it's a literal asteroid belt around Saturn! 🧪🔭☄️
Saturn's outer moon system viewed from the north pole of Saturn. Moons orbiting in clockwise (retrograde) orbits have red-colored orbits while moons orbiting counterclockwise (prograde; in the direction of Saturn's spin) are colored blue. With so many irregular moons occupying the same region and intersecting each other, the irregular moon system looks like a donut-shaped vortex surrounding Saturn. Each of the 128 new moons is highlighted in the diagram with a white point representing their location, and a brighter-colored orbit. Previously-known moons of Saturn are included in the diagram, but are colored darker. The regular moons of Saturn are colored turquoise and the outermost regular moons (Titan, Hyperion, and Iapetus) labeled with their name. At the lower left corner are scale indicators to help visualize the scale of Saturn's irregular moon system. A small gray circle at the left left corner is shown to represent the diameter of the Earth-Moon orbital distance. A linear scale bar is labeled "10 million km" (6.2 million mi) to give a standard distance. View of Saturn's irregular moon system, tilted at an angle to show the toroidal belt-like shape of the system. Each moon is labeled with their names in turquioise. Red orbits = retrograde direction, and blue orbits = prograde direction. Turquoise curves closer to the center are orbits of Saturn's regular moons. Side view of Saturn's irregular moon system, tilted at an angle to show the toroidal belt-like shape of the system. Red orbits = retrograde direction, and blue orbits = prograde direction. Turquoise curves closer to the center are orbits of Saturn's regular moons. The irregular moons of Neptune (dark green) are also visible in the background to the right of Saturn. The horizontal red line protruding right of Saturn is the orbit path of Saturn.

The problem is that traditional search engines have been totally and utterly destroyed to the point where I don’t know if they can outperform ChatGPT (despite the occasional hallucinations)

I took a course in college that spent half a semester on Ulysses, and half a semester on HBO’s The Wire. No supplementary materials were provided. To this day it’s one of the coolest classes I’ve ever taken

In 2018 I was literally skipping my history classes in college to watch the chess24 broadcast of Carlsen-Caruana. It was the only place to get real commentary blended with banter and dry humor. It made me fall in love with chess.

Needless to say that the chess world was more spoiled than it knew
