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."

pmontra writes "The City of Venice, Italy, started to offer free Wi-Fi to residents (Google translation from the Italian source) on July 3 2009. Tourists and other visitors will pay 5 Euros a day for the service starting from September. The hot spots are connected to a ten thousand kilometer (6,250 mile) fiber optic LAN the City started deploying in the '90s. The first day of free Internet access has been celebrated with a digital treasure hunt in the channels of the lagoon city."

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.'"

jadoon88 writes to share a series of old Atari 7800 games that have been unofficially open sourced. "Remember Dig Dug or Centipede or Robotron? They used to be favorites when Atari's 7800 series was still around. Since the era of those consoles is over, and a different world of interactive reality gaming has taken over, Atari has unofficially released source code of over 15 games for the coders and enthusiasts to admire the state-of-the-art (because this is what it was back then). During those times, nobody would have imagined in their wildest dreams the games that Atari's developers floated into the gaming thirsty market and instantly swept across continental boundaries. But things changed soon after that and a company once regarded as one of the most successful gaming console manufacturers and developers faded away in the pages of our technology's hall-of-fame."

cheezitmike writes "Researchers at Oregon State University are testing a new type of wave-energy converter to generate electricity from ocean waves: 'Even when the ocean seems calm, swells are moving water up and down sufficiently to generate electricity. ... For decades the challenge has been to build a device that can withstand monster waves and gale-force winds, not to mention corrosive saltwater, seaweed, floating debris and curious marine mammals. ... In the most recent prototypes, a thick coil of copper wire is inside the first component, which is anchored to the seafloor. The second component is a magnet attached to a float that moves up and down freely with the waves. As the magnet is heaved by the waves, its magnetic field moves along the stationary coil of copper wire. This motion induces a current in the wire — electricity.'" Meanwhile, researchers at Stanford are working to design "turbine kites" that operate at 30,000 feet, where air currents flow much faster than they do close to the ground. Ken Caldeira, a Stanford associate professor, said, "If you tapped into 1% of the power in high-altitude winds, that would be enough to continuously power all civilization."
