This assumes that the names assigned to WiFi access points have any relationship to reality.

Do you get your coffee from the Urban Coffee Lounge or the Starbucks before going to Juanita Beach Park, there in Kirkland, WA?

Nope, no relation to reality whatsoever.

It would also require notching out the TDWR frequencies, instead of allowing them to be used with DFS. I suppose someone could create a fuse controlled radio chip which could be used worldwide, and fuses blown during manufacturing to limit the hardware as required, but somehow I don't think the market is big enough for that to happen anytime soon.

Yep. And the summary completely misses the part which is likely to upset most /. users:

Accordingly, we are adopting the proposal in the NPRM that manufacturers must take steps to prevent unauthorized software changes to their equipment in all of the U-NII bands

That may effectively put an end to all the Linux based APs (DD-WRT, Tomato, OpenWRT, etc.)

Reading is fundamental.

Because the two academic authors merely designed the research and wrote the paper, they would not seem to have been involved, then, in obtaining either data or informed consent.

Cites, please? Because I have one which counters that claim.

Importantly -- and contrary to the apparent beliefs of some commentators -- not all HSR is subject to the federal regulations, including IRB review. By the terms of the regulations themselves, HSR is subject to IRB review only when it is conducted or funded by any of several federal departments and agencies (so-called Common Rule agencies), or when it will form the basis of an FDA marketing application. HSR conducted and funded solely by entities like Facebook is not subject to federal research regulations...

Privacy Oversight Board Gives NSA Surveillance a Pass 170

An anonymous reader writes There's an independent agency within the U.S. government called the Privacy and Civil Liberties Oversight Board. Their job is to weigh the benefits of government actions — like stopping terrorist threats — against violations of citizens' rights that may result from those actions. As you might expect, the NSA scandal landed squarely in their laps, and they've compiled a report evaluating the surveillance methods. As the cynical among you might also expect, the Oversight Board gave the NSA a pass, saying that while their methods were "close to the line of constitutional reasonableness," they were used for good reason. In the completely non-binding 191-page report (PDF), they said, "With regard to the NSA's acquisition of 'about' communications [metadata], the Board concludes that the practice is largely an inevitable byproduct of the government's efforts to comprehensively acquire communications that are sent to or from its targets. Because of the manner in which the NSA conducts upstream collection, and the limits of its current technology, the NSA cannot completely eliminate 'about' communications from its collection without also eliminating a significant portion of the 'to/from' communications that it seeks."

Want to elaborate? Like with some facts and not just a blanket dismissal?

It's been done using a PIN photo-diode. I make no claim that it could be done with a 20 year old consumer camcorder, but there were pro cameras with 1/20,000 shutter speeds available. Whether that applied on a frame or pixel basis, I don't know, so I'm not willing to dismiss the possibility out of hand, as you do. It's believable to me that there were commercially available cameras capable of doing it.

An NTSC video camera records ~480 scan lines every 1/30 second. So, a full scan line would represent about 1 bit at 14400 bps. If you recorded a de-focused LED, so it was recorded full frame, you'd get the bits if the sensor were fast enough (i.e. didn't integrate over the time between scans). If rx/tx were different colors, you could probably get both at once. It should be relatively easy to decode, but you'd be missing some bits during vertical retrace.
