It's this.

And on the compression side, there's a lot of really cool stuff that lets it happen. For example, it dynamically resizes the blocks from 2x2 to 256x256, and they don't even have to be square. It may apply DCT in one, AFAS in another, etc - whatever is most efficient. It uses edge preserving filters to keep the edges of features clean. It can draw in splines and clone regions from one part of an image to another. Where it has to throw away high frequency noise (film grain, noisy textures, etc), it statistically samples the properties of the noise and saves that, and then regenerates equivalent noise. In "busy" areas, like say tree bark or whatnot (where the human eye isn't good at discerning changes), it throws away more precision there, and instead allocates it to details located in fragile flat areas, such as skin and shadows, that the eye is attracted to. It works in default in XYB colour space, based on the actual interactions of the cones in the eye, so it can aggressively quantize things which the brain cannot detect. And in the choice between fast but not-great Huffman coding vs. better but slow and patent-encumbered arithmetic coding, they instead use rANS, which is nearly as fast as Huffman but as efficient as arithmetic coding, and faces no patent challenges. Which is also why you can take a legacy JPEG and rapidly losslessly reincode as JPEG-XL and get a file that's ~20% smaller - you're swapping Huffman for rANS.

(That's the lossy mode - there's also a dedicated lossless mode)

Who is "we" here? Certainly not a failing country that will absolutely cut every corner.

Yes. Chatrie v. United States (No. 25-112), the U.S. Supreme Court ruled 6â"3 that law enforcement's use of a Google geofence warrant to acquire a person's historical cellphone location data constitutes a "search" under the Fourth Amendment.

That was a ruling on a search which required a warrant, and the ruling states that the district court itself found that the warrant was invalid as it violated the suspect's fourth amendment rights. It would seem to apply except that these are warrantless requests. It also specifically references Carpenter v. United States' determination that such a request as in Chatrie is able to look into the past, which makes possible surveillance which was formerly impossible and was therefore unexpected when the relevant laws were written, but the flock requests we're discussing are for recent information. It remains to be seen whether this court would apply the same logic to these similar but different specific uses.

When Russia started this they were not expecting a war. They were confident that the Ukrainians would welcome them.

That's certainly what Putin said, but it's not clear why you would believe it when they went into Ukraine with military vehicles, not with a brass band and a parade, unless... have you suffered some major head injury recently?
