Federal judge rules in favor of cell phone privacy Message-ID: <Pine.NEB.4.64.1011092118370.4261@panix5.panix.com> (hat tip to Lauren Weinstein of Privacy Digest) A federal judge has ruled that subscriber data captured from cellphone towers is protected by the US Constitution's Fourth Amendment guarantee against illegal searches and seizures. The decision is part of a sea change from half a decade worth of previous rulings, in which police weren't required to obtain search warrants based on probable cause before accessing the subscriber information. US Magistrate Judge Stephen Wm Smith of the Southern District of Texas said recent changes in case law and rapidly evolving mobile technology required a departure from the outcomes in that long line of cases. ... "In 1789 it was inconceivable that every peripatetic step of a citizen's life could be monitored, recorded, and revealed to the government," he wrote in a decision that was released late last month but only noticed in the last few days. "For a cell phone user born in 1984, however, it is conceivable that every movement of his adult life can be imperceptibly captured, compiled, and retrieved from a digital dossier somewhere in a computer cloud. Now as then, the Fourth Amendment remains our polestar." ------ rest: http://www.theregister.co.uk/2010/11/05/cellphone_data_protected/ ------------ http://www.aclu.org/files/pdfs/freespeech/2010_1029_texas_cellphonetracking_opinion.pdf _____________________________________________________ Knowledge may be power, but communications is the key dannyb@panix.com [to foil spammers, my address has been double rot-13 encoded]

Dentsu will be responsible for the selling and creative execution of iAds in Japan, and Apple will host, target and deliver the iAds to its iPhone and iPod touch users. iAd was launched in the US in July and has emerged as a powerful new way for leading brands to reach the tens of millions of iPhone and iPod touch users, while providing a significant new revenue stream for developers. ... http://www.apple.com/pr/library/2010/11/09iads.html

Does it have anything to do with the number of pairs on a 66 block? (24 pair for voice/data channels, one for timing, etc.). I'm not sure why I remember this. Gordon L. Burditt ***** Moderator's Note ***** Probably not: 66 blocks are for 25-pair cable, of course, but T-Carrier banks were always wired to CO frames, with at least 3 pairs per channel (TR, T1R1, E&M).

Second, they could reliably transmit and decode 24 channels between manholes, but not 36 (too many errors due to transmission distortion). Another point of trivia: At one time, they had digital switching of analog carrier channels: Transmission between cities was analog, but the switches were digital. Dick ***** Moderator's Note ***** Although T-Carrier banks had to interface with Analog banks, the connections were always at "baseband", i.e., 300-4,000Hz connections on pair wire. The Analog banks could never interoperate with T-Carrier banks on the "high speed" side of the banks: a "T-1" 1.544 Mbps circuit can't feed an analog carrier system. Apples and Oranges, really.

Subject: Re: MSNBC on text message spam Message-ID: <fa9kd615tsi205jvqab2m1nhtcv8cc2sot@4ax.com> I don't text and I tell my friends not to text to me. [I'm a Luddite who only uses a mobile phone to talk. No texting, no cameras, no web browsing.] Fortunately I don't get spam texts, except from my mobile-phone company Tracfone. Once a month or so, Tracfone sends an advertisement via text. When I buy additional months service and/or airtime minutes, Tracfone sends a text message to my phone to update the expiration date and minutes automatically. That's cetainly more convenient that when I first started with Tracfone: I would visit their website, or call their toll-free number, to arrange the update, and then I would have to enter a zillion digits into the phone.
