The thing this reply guy doesn’t get, the thing that’s so crucial to this moment, is that being correct about the law counts for absolute diddly shit in the moment. The law is slow. The law comes later…if ever. With these people on our streets right now, the only thing that matters in the moment is what people believe: what they believe the law is, what they believe is safe, what they believe they can get away with, what they believe they are capable of doing.
The law is slow. The law catches up later. Belief is •now•.

It is now less than than 12 months to the midterm elections.
And the D-party is about as ready and organized as a bag of live worms.
The R-party is ready with massive tools to exclude voters; block, disrupt and manipulate the vote counts; and otherwise assure that the election comes out their way.
But the D's still hang onto leaders and issues (I'm lookin' at you "identity politics") that are like boat anchors on a parachute.
I am old, but I firm…

“For voters opposed to Reform UK, tactical voting represents the most obvious counterstrategy – one of the explanations for the lopsided result in the Caerphilly byelection (which used FPTP). But to be effective, tactical voting requires clear information: voters must know which party has the best chance of defeating Reform UK in their own constituency."
Reform holds 11% lead over Plaid Cymru in Westminster election poll, as centre left vote fragments in Wales

Solar power just hit a new milestone. Chinese researchers broke the 10% efficiency barrier for selenium solar cells for the first time, reaching 10.3%.
What makes this exciting: selenium cells have wider bandgaps and high efficiency potential. The team used optimized contacts, light-driven crystallization, and special annealing techniques.
The result? Stable devices that lost minimal efficiency after 1,000 hours of testing.

Abstract: This work introduces a novel dissimilarity measure between two convex cones, based on the max-min angle between them. We demonstrate that this measure is closely related to the Pompeiu-Hausdorff distance, a well-established metric for comparing compact sets. Furthermore, we examine cone configurations where the measure admits simplified or analytic forms. For the specific case of polyhedral cones, a nonconvex cutting-plane method is deployed to compute, at least approximately, the measure between them. Our approach builds on a tailored version of Kelley's cutting-plane algorithm, which involves solving a challenging master program per iteration. When this master program is solved locally, our method yields an angle that satisfies certain necessary optimality conditions of the underlying nonconvex optimization problem yielding the dissimilarity measure between the cones. As an application of the proposed mathematical and algorithmic framework, we address the image-set classification task under limited data conditions, a task that falls within the scope of the \emph{Few-Shot Learning} paradigm. In this context, image sets belonging to the same class are modeled as polyhedral cones, and our dissimilarity measure proves useful for understanding whether two image sets belong to the same class.

The old Valve #Index has the best audio of any VR headset.
The goofy floating speakers sound great, and are incredibly immersive, because the sound literally comes from "outside" instead of touching my ears or conducting sound through my bones like in-ear headphones.
