These guys access a car, pay at teh pump gass, and other RFID services.
While MasterCard and Texas Instruments state that the new credit cards use a new RFID security, i suspect it will not be long before it is also comprimised.
Imagine walking down the street and some guy bumps you. You check your wallet, and it is still there, but the theif stole your RFID data and is alrady on his way. Your sense of security is physical security. I still have my card in my pocket, therefore, it must be secure. Guess again.
As I recall, CRAY owns the OS and you license it. So, if you happened to buy a computer, you could never run it unless you could fork out the cost of the OS license and maintenance for the servers. Besides, who could afford the electricity and cooling?

Adults can get in for $3.00 Site: my.execpc.com/~cfmit/ Museum of Industry and Technology 21 East Grand Avenue Chippewa Falls, WI 54729 715.720.9206 tel
The University of Minnesota also has a Virtual Cray Museum. http://www.cbi.umn.edu/exhibits/cray/index.html

If you have ever serviced a laser printer, you would know that the Fuser Assebly, the drum that melts the toner on the paper, gets pitted and scared during use. No fuser is perfect. Each leaves a small mark or blemish on the paper with each roll.
It seems to me this would be like id'ing a tiretrack. Look for the scars/imperfections and match it to a fuser.
Inkjets are much harder to id. Since the printing comes from the Print head, and it only drops ink, your best bet is to match a dirt print head or dirty roller.
If you have seen CNN in the past year, you know what will happen to broadcast television. The next logical wave is to incorporate advertising into the program.
It will either exist in the form of in program advertising, watermarking, or scrollers and overlays in the program.
None of these are new concepts. However, consumers way decide which model is adopted. If the program is a movie where the viewer is absorbed into the program, in program product placement will dominate. If the program is news or talk show related, you will see scrollers and drop downs in the programs.
Tivo will never be able to remove the advertising from the media stream, it can only allow you to scan ahead until there is not ad present.
I love Tivo, I hate ads... The only last choice may be subscription programming. I may be more willingto view a program without ads at a fee than deal with the barage of ads I get today.

In order to be verifiable, you need the paper output. If they voting machines would generate a unique paper output from each machine as a backup, votes could be recounted and audited.
Each paper ballot could be encrypted and stored in 2D electronic barcode. It would be easy to scan and verify and data could not be altered without invalidating the crc's.
Electronic voting will never be stand alone until we have a valid way to audit the results.

Is is possible to piggy back onto an existing permit? Example? If the city was to hold a "Movies in the Park" night. Does the city need a permit for the movies since more than a few people will be present? If so, the Mob would have every right to attend and 'perform'.
If the mob showed up at a little league baseball game? Did the game have a permit prior to the event? They already have 18 players and 2 coaches. I don't see how the mob could be fine fined or arrested for gathering at these types of locations.
Many cities have laws limiting the number of people who are allowed to gather without a permit. The way I see it, flash mob where you know the groups are allowed and bypass the entire issue of groups gathering without permits.
The Mall of America was a bad location! The mall is notorious for being a privet location. But, does this mean that the mall cannot have crowds? No. The mall is notorious for crowds. The worst that can happen to the flash mobbers is that the police ask them to leave. At which point, since this is a very short lived event anyways, they disperse.
The problem comes when people decide to gather anyways and become loud. Shouting makes the mob into a public nusence (sp?). If they are too loud, they break the law. The Minneapolis Mob outside of the Sears store had one thing in its favor. No talking! They had no signs and had no message to share. They gathered briefly and peacefully.
Which brings me back to topic. Where is a permit required if groups are already allowed to gather? The mall? Baseball Games? Restaurants? Theaters? These venues do not require a permit for these type of events because we have come to expect these events to be peaceful. Once the city accepts that these mob events are peaceful and non political in nature, the same will come to pass.

The problem with Fluorinert is tha the fumes from the substance is highly toxic if it catches fire. The Cray 2 systems keep the liquid tightly contained so even the vapors do not escape.
I would imageine that if you wanted to submerge your PC in Fluorinert, you would have to create a sealed enclosure and a pump system.
Between the risk of death and the price, ($1k/quart) you are better off buying a mini-fridge at Walmart for $40.00 and moding it to hold your case and power supply.
