As a point of reference, meet Rowan the intrepid woof. Together we invented the game of Dragon Soccer involving two soccer balls and a stuffed dragon. The rules are complicated… and fluid. But it seems that whoever controls the dragon controls the game. I’ll be posting numerous pics of Rowan.
When Rowan was a puppy she enrolled in several self-guided courses. After excelling in Basic Couch Use 101, she then took Principles of Pillowing 101, and Advanced Pillowing 240. Scored well in both. A genuine autodidact. 😊

a delightful description of the ice slipperiness problem and the explanations that folks have proposed!
The textbook explanation for ice’s slipperiness emerged from experiments in the 1930s at the Jungfraujoch Ice Palace, a human-made ice cave in the Swiss Alps. Today, many scientists disagree with it.
Why Is Ice Slippery? A New Hypothesis Slides Into the Chat. | Quanta Magazine
A newly proposed explanation for the slipperiness of ice has revived a centuries-long debate.

Rowan the intrepid woof couldn’t find any frogs along the edge of the pond this time of year, so instead she decided to study waves. Seems to like fluid mechanics as much as aquatic biology. 😊

Oh gosh our befriended dragon Icarus was seriously injured in a game of Dragon Soccer! Fortunately the Chief Woof does excellent dragon surgery (generally a dangerous business) and fixed Icarus’s noise-maker innards and the laceration. Look at those beautiful butt/tail stitches! All better 😊

The true cost of “solar power at night” with Reflect Orbital
If you played SimCity 2000, you might've loved the idea of "beaming power from space" down to Earth.
Reflect Orbital took that idea, tech-bro'd it, and now could end "night" as we know it.

Indeed, based on my reading of the document sent to the nine universities, the “compact” consists of open-ended extortion, and any “benefits” of signing on are an illusion.
This is absolutely right on every point and everyone who sits on a governing board or serves as president or provost or similar should please make the time to read it.

It’s not just cost. Digital sovereignty and privacy matter. The migration from Microsoft (Windows, Office) to Linux and open-source software (e.g. LibreOffice) is accelerating. This is just one notable example among many.

It's not about the cost savings, either. Many government organizations are replacing Microsoft software for a more important reason.
