Alas, "Pop-ups warn of infections" is the mechanism as well of the purveyors of malicious software. I'd fear that Comcast users who're aware of that fact will ignore Comcast's pop-ups, while Comcast users who're more naive will come to trust even _un_trustworthy pop-ups. Not all that clear which side will be the ultimate beneficiary. Cheers, -- tlvp -- Avant de repondre, jeter la poubelle, SVP

I have seen many freak propagation events at what should be line-of-sight frequencies. I live in Pahrump, NV, separated from Las Vegas by a mountain range whose peak elevation is about 8000 feet above local terrain. One night I had a 2-way 10-minute contact on 2 meters (146 MHz) ham radio with a station on the other side of the mountains, direct from his car to my car, no repeaters. We tried it again for several nights following, but never could repeat it. We must have gotten a lucky bounce off something in the atmosphere. In the middle 1970's, I lived in southern New Hampshire, 20 miles north of Boston. One night, while watching TV Channel 2 from Boston of the air, the picture got strong interference. When the interference cleared, I was watching channel 2 from New York City, 200 miles away. The New York signal completely overrode the Boston signal. This lasted a couple of hours. I never saw the phenomenon again.

The whole point was that the signal from this handset was acquired by one of the many directional antennas in the opposite direction that it was supposed to work because the radiation envelope still had a significant node that would work in the direction the handset was claimed to be located by the defence. Anyone that has worked with microwave equipment knows that unidirectional antennas are not 100% directional, and there are significant usable nodes outside of the direction most of the signal is supposed to go. IIRC in this case the handset was (claimed to be) reasonably close to the base station on the opposite side of the direction the prosecution claimed as part of the evidence that resulted in a conviction, but post-trial other experts showed that it could well have been located where the defence actually claimed with all the factors of base station operation taken into account. The main point was that the initial evidence showed an over-simplistic description of "perfect" antenna radiation patterns of all the microwave antennas on this tower (which was probably initially done with good intentions to simplify things for a non-technical audience - the jury) and told that the signal could only have come from one direction, which was patently incorrect. -- Regards, David.

I would appreciate seeing any versions that you all may have and any recollections of where you have encountered it, and if anyone has seen it in the context of telephone equipment or CO locations, and if anyone can confirm which trade magazines may have printed it. Here is the version as displayed by Wikipedia: ACHTUNG! ALLES TURISTEN UND NONTEKNISCHEN LOOKENPEEPERS! DAS KOMPUTERMASCHINE IST NICHT FÜR DER GEFINGERPOKEN UND MITTENGRABEN! ODERWISE IST EASY TO SCHNAPPEN DER SPRINGENWERK, BLOWENFUSEN UND POPPENCORKEN MIT SPITZENSPARKSEN. IST NICHT FÜR GEWERKEN BEI DUMMKOPFEN. DER RUBBERNECKEN SIGHTSEEREN KEEPEN DAS COTTONPICKEN HÄNDER IN DAS POCKETS MUSS. ZO RELAXEN UND WATSCHEN DER BLINKENLICHTEN. This differs somewhat from my recollection and indeed the Wikipedia article states that a great many versions existed. Michael ***** Moderator's Note ***** This timeless warning was briefly popular at the start of the computer revolution in the U.S., but use subsided amid acccusations of politically-incorrectness because of the "Ginglish" language. Still, it gets high marks for effectiveness: I saw it taped to a #1ESS control panel in 1974. Politicall-incorrect or not, it still has a place beside other timeless warnings: (Next to a paper cutting machine) "Cut fingers will fall on this side. Please dispose of properly." (In the MIT Laser Lab) "Do not look into laser with remaining eye." (On the wall at a driver-training school) "Do not bet on your ego in a fight with the laws of physics. Physics wins every time!" (On the desk of a probabtion officer in a Massachusetts courthouse) "Attention, teenagers: 'No' is a complete sentence." I'm sure there are others. ;-) Bill Horne Moderator

Fortunately, a judge says that relationship isn't enough to squash a rights group's open records request for communications between the nation's telecoms and the feds. The Electronic Frontier Foundation wanted to see what role telecom lobbying of Justice Department played when the government began its year-long, and ultimately successful, push to win retroactive immunity for AT&T and others being sued for unlawfully spying on American citizens.

BUT ... T-Mobile is still cautioning all users to "please DO NOT remove your battery, reset your Sidekick, or allow it to lose power" on the off-chance T-Mobile stumbles upon a miracle by Monday and recovers all the lost data (contacts, calendars, to-dos, photos, etc.) " T-Mobile and the Sidekick data services provider, Danger, a " subsidiary of Microsoft, are reaching out to express our apologies " ... "Microsoft/Danger server failure"? That raises red flags. :-) Full story here: http://forums.t-mobile.com/tmbl/board?board.id=06 And I was only grousing about losing some phone numbers when my AT&T SIM went belly-up. I feel for those who got sucked into the cloud computing concept. Another article [about] why cloud computing is NOT for enterprises or, for that matter, anyone: http://www.enterprisestorageforum.com/technology/features/article.php/3843151 ***** Moderator's Note ***** I've got to tip my hat to Microsoft for having the confidence to name a data-retention service "Danger". Maybe they should invest in the "Cancer" brand of cigarettes ... Bill Horne Moderator

Message-ID: <3b3f71c3-f2c8-4433-a438-24afd364419b@d10g2000yqh.googlegroups.com> Some questions... Is it still true that a cell phone that is no longer in service with a carrier can still be used to dial 911? Will such a phone transmit the GPS coordinates? Can the phone be called back by the 911 center? They can seize a landline and ring it back, but what about a cellphone or a disconnected cellphone? What calling number shows up at the 911 center from a disconnected cell phone? Thanks! Any other info would be appreciated.
