This never worked well. The social filter is pretty good. But I am on one mailing list which ends up in Promotions about 2/3 of the time, despite my repeatedly telling GMail to deliver it to Forums instead, and despite the mailing list having no commercial content whatsoever. The filter for Updates is really whacked; anything can end up in here, and the stuff that should go here can end up in Forums, Promotions, or Primary instead.
The new thing sounds similar, but on steroids. More like using labels (which are GMail's equivalent of folders to file email into, except that emails can have more than one label and so the folders aren't exclusive), but letting Google determine the labels by itself. We'll see how good that works.
It's a problem, though, because there's no simple metric to determine whether patent examiners are doing a good job. Using number of patents reviewed as that metric encourages examiners to do a shoddy job actually examining the patents (i.e. what has actually been happening). If they are expected to pass only a certain fraction of patents, this is slightly better since it forces them to actually come up with reasons to reject some patents, but what fraction should they use? Two examiners doing perfect jobs may have very different fractions of accepted patents simply because one got better patents to review than the other, especially if they have different focus areas. Does the patent office even know the fraction of submitted patents in various areas which are good? A better metric would be whether accepted patents survive in the courts, but this depends on somebody actually challenging the patents and takes years after the fact. It might help now throw out some of the patent examiners who clearly haven't been doing their jobs in the past.
I'm not sure what the right solution is. Blind peer review and multiple review? Assign each patent to 2 or 3 different reviewers and call to carpet the ones who most consistently differ from others? Does that even work if half your patent examiners are shirking?
About 4 or 5 years ago, all the broadcast TV in the US changed over to a digital format, and the digital format includes HDTV broadcasts. If you have an HDTV and an antenna, and you live in a place where you can receive the signals, you can get the HDTV of all the broadcast networks over the air (OTA) with no cable.
It has been reported that Comcast re-compresses the digital HDTV streams, cramming them into a smaller digital channel in their cable system, in order to fit more channels in. This leads to reduced quality in the picture you view on Comcast compared to the OTA HDTV broadcast. I don't know about other cable systems. Here is one such report, though it seems to be specifically about other non-OTA HD channels (where the FIOS broadcast was used for comparison).
The first stage is to orbit a cubesat, a tiny, coffee can sized satellite that would contain two highly accurate accelerometers that would go into orbit around Europa and measure its gravity field. In this way the location of Europa's subsurface oceans would be mapped. Indeed it is possible that the probe might find an opening through the ice crust to the ocean, warmed it is thought by tidal forces.
The second stage is to deploy even smaller probes called chipsats, tiny devices that contain sensors, a microchip, and an antenna. Hundreds of these probes, the size of human fingernails, would float down on Europa's atmosphere to be scattered about its surface. While some might be lost, enough will land over a wide enough area to do an extensive chemical analysis of the surface of Europa, which would then be transmitted to the cubesat mothership and then beamed to Earth.
