Harry writes "In 1968, computers tended to occupy entire rooms, and were therefore hard to take with you. But Computerworld reports on Anderson Jacobson's 75-pound Teletype-terminal-in-a-case, an early attempt to let folks compute from anywhere. (Well, anywhere they had power and access to a telephone for the Teletype's acoustic coupler.) Wheels were optional."

Slatterz writes "The Tesla Roadster has almost mythical status among electric car enthusiasts. It's fast, with high torque over a wide RPM range, and can beat a Ferrari in terms of acceleration. Now Tesla has released new video of its upcoming new electric car, called the Model S, which Tesla Motors claims is the world's first mass produced fully-electric vehicle. Unlike the Lotus-Elise based Roadster, the Model S is a traditional sedan of the type millions of commuters might actually drive. Tesla claims it will fit seven people, and has mounted a rather large 17in LCD in the dash. Key to Telsa's future will be the evolution of lithium-ion battery technology. Tesla Motors claiming the new Model S can travel up to 300 miles on a single charge, but the battery will still take 45 minutes to quick-recharge." (And for those in countries where it matters, this article mentions that it should also be available in right-hand drive.)

An anonymous reader writes "A new Canadian study deconstructs how copyright lobby groups manipulate public opinion by laundering proposals through seemingly independent groups. The study started after the Conference Board of Canada was shown to have plagiarized several of its IP reports and now shows the connections that all lead through the MPAA and RIAA. Micheal Geist writes, 'It is not just that these reports all receive financial support from the same organizations and say largely the same thing. It is also that the reports each build on one another, creating the false impression of growing momentum and consensus on the state of Canadian law and the need for specific reforms.'"

Oracle Goddess writes "After 30 years, CompuServe is all but dead, as AOL has pulled the plug on the once-great company. The original CompuServe service, first offered in 1979, provided its users with addresses such as 73402,3633 and was the first major online service. CompuServe users will be able to use their existing CompuServe Classic (as the service was renamed) addresses at no charge via a new e-mail system, but the software that the service was built on has been shut down. Tellingly, the current version of the service's client software, CompuServe for Windows NT 4.0.2, dates back to 1999."

An anonymous reader sends news that TerreStar-1, the largest satellite ever made for the purpose of telecommunications, successfully launched earlier this week from a European spaceport. Its launch weight was 6,910 kg, and it is "distinguished by a giant, 60-foot (18-meter) wide S-band antenna that will be unfurled in the coming weeks. Once the satellite's two solar wings are deployed, TerreStar-1 is expected to have a wingspan of about 106 feet (32.4 meters). ... It is designed to provide mobile voice and data communications in North America to smartphone-size handsets using the 2-gigahertz, or S-band, portion of the radio spectrum. The system is designed to function with a network of ground-based signal amplifiers to permit service in areas the satellite cannot reach, such as urban canyons and areas outside the line-of-sight view of the spacecraft." Video and details of the launch are available from the ESA.

Hugh Pickens writes "TechCrunch's Michael Arrington has been talking for a year about building a touch-screen tablet for Web surfing and now it appears that the CrunchPad is close to becoming a reality. 'We're going to make some really big announcements,' said Arrington, who predicted a prototype would be ready for unveiling by the end of July. The purpose of the CrunchPad will be very simple: surfing the Web. Turn it on and up comes a browser — 'an Internet consumption device,' for reading, checking e-mail or watching video. The CrunchPad will not have a hard drive or keyboard and photos of the latest prototype show a device with a 12 inch screen. 'The screen is now flush with the case and we've decreased the overall thickness to about 18 mm,' writes Arrington. 'The case will be aluminum, which is more expensive than plastic but is sturdier and lets us shave a little more off the overall thickness of the device.' The CrunchPad boots directly into the browser with a Linux-based operating system and a WebKit-based browser. A video of an earlier CrunchPad prototype in action shows a device which, unlike the iPhone, runs flash. 'The next time we talk about the CrunchPad publicly will be at a special press and user event in July in Silicon Valley,' writes Arrington. 'We're full on. These prototypes are real.'"

CNet reports that the lawyers representing Jammie Thomas-Rasset have confirmed she will be fighting the $1.9 million verdict handed down in her case against the RIAA. "The Recording Industry Association of America said on Monday that it had made a phone call to Sibley and law partner Kiwi Camara last week to ask whether Thomas-Rasset wanted to discuss a settlement. An RIAA representative said that its lawyers were told by Sibley that Thomas-Rasset wasn't interested in discussing any deal that required her to admit guilt or pay any money. ... 'She's not interested in settling,' attorney Joe Sibley said in a brief phone interview. 'She wants to take the issue up on appeal on the constitutionality of the damages. That's one of the main arguments — that the damages are disproportionate to any actual harm.'"

thefickler writes "Clearly, the rise of free antivirus is starting to worry Symantec, with one of their top executives warning consumers not to rely on free antivirus software (including Microsoft's Security Essentials). 'If you are only relying on free antivirus to offer you protection in this modern age, you are not getting the protection you need to be able to stay clean and have a reasonable chance of avoiding identity theft,' said David Hall, a Product Manager for Symantec. According to Hall, there is a widening gap between people's understanding of what protection they need and the threats they're actually facing."

Ponca City, We love you writes "David Ropeik writes at MSNBC that there's a lot more to making a basic firework display than putting a fuel source and an oxidizer together. Pyrotechnic chemists, who are trying to create bedazzlement instead of bang, don't want their work to explode, but to burn for a bit, so it gives a good visual show. To achieve the desired effect, the sizes of the particles of each ingredient have to be just right, and the ingredients have to be blended together just right. To slow down the burning, chemists use big grains of chemicals, in the range of 250 to 300 microns, and they don't blend the ingredients together very well, making it harder for the fuel and oxidizer to combine and burn, thus producing a longer and brighter effect. Surprisingly few emitters are used in pyrotechnics, and there are no commercially useful emitters in blue-green to emerald green in the 490-520 nm region. Energy from the fire in the basic fuel is transferred to the atoms of the colorant chemicals, exciting the electrons in those chemicals into a higher energy state. As they cool down, they move back to a lower state of energy, emitting light. So, you actually see the colors in fireworks as they're cooling down. To get the really tricky shapes, like stars or hearts, the colorant pellets are pasted on a piece of paper in the desired pattern. That paper is put in the middle of the shell with explosive charges above it, and below. When those charges go off, they burn up the paper, and send the ignited colorant pellets out in the same pattern they were in on the sheet of paper, spreading wider apart as they fly."

schliz writes "Researchers behind the world's largest quantum encrypted network said the technology could secure business networks inside six years. The prototype Quantum Key Distribution network was built by the Secure Communication Based On Quantum Cryptography (SECOQC) group last year. It is described in a journal paper published by the Institute of Physics this week, which includes details on how it is based on the trusted-repeater paradigm."
