Via the EFF comes news that, during a case involving the use of a Stingray device, the DOJ revealed that it was standard practice to use the devices without explicitly requesting permission in warrants. "When Rigmaiden filed a motion to suppress the Stingray evidence as a warrantless search in violation of the Fourth Amendment, the government responded that this order was a search warrant that authorized the government to use the Stingray. Together with the ACLU of Northern California and the ACLU, we filed an amicus brief in support of Rigmaiden, noting that this 'order' wasn't a search warrant because it was directed towards Verizon, made no mention of an IMSI catcher or Stingray and didn't authorize the government — rather than Verizon — to do anything. Plus to the extent it captured loads of information from other people not suspected of criminal activity it was a 'general warrant,' the precise evil the Fourth Amendment was designed to prevent. ... The emails make clear that U.S. Attorneys in the Northern California were using Stingrays but not informing magistrates of what exactly they were doing. And once the judges got wind of what was actually going on, they were none too pleased:"
Correct. Also, it's important to point out that the Mach number of a vehicle is a local measure of vehicle speed. As the speed of sound varies with temperature, and thus altitude, you'll find that two vehicles having the same trace ground speed but that are flying different altitudes will be at different Mach numbers. Acoustics and aerodynamics are fun.
Here is an even more obscure privacy setting. If you read through the privacy page here...
You'll notice about halfway down the page in the "cookies and other technology" section a discussion of interest based advertising, which is basically iAd's targeted at you based on your usage habits. The only way to opt out of this "feature" on an iOS device is to click on the link in that paragraph to http://oo.apple.com/ from Safari on your iOS device, which will bring you to a settings page that will allow you to disable "interest based iAds". I have not found a way to get to this setting page through the settings App (queue up the people who will promptly correct me).
