eviltangerine writes “Twitter user stroughtonsmith was dickering around with the carrier bundle files for his developer version of the iPhone 3.0 OS and enabled the USB tethering options. Apparently he has even been able to use his laptop to access the internet over the USB tether. MacRumors comments that while Apple has announced the availability of tethering, it hasn’t hashed out the details with the mobile carriers (probably so they can charge more in fees). No word on connection speed, but here are some pictures of his phone while tethering.”

Brietech writes “This is a homebrew laptop project based on a Picaxe microcontroller. It has 16kb of RAM, 256kb of storage, sound and a self-hosted development environment! It has a simple CLI, file-system, ‘EMAXE’ text editor and a programming language called ‘Chris#.’ Oh, and yes, it runs Linaxe.”

Avram Piltch writes “Last week, LAPTOP reported that Office Depot employees were routinely lying to customers about notebook inventory, telling them that systems were out of stock if they didn’t want to buy extended warranties or tech services. Now LAPTOP has spoken to more Office Depot associates, one of whom goes by the name Alex and reports widespread altering of prices in his region. He says he even Photoshops higher price tags on clearance notebooks so that associates can tell customers that they’re getting a free warranty or tech service, when the price has been raised to cover it. LAPTOP also talked to a representative from the FTC, who would not comment on Office Depot specifically, but said that the sales practices described by LAPTOP clearly violate federal law.”

narramissic writes “Two separate research teams have found that the electromagnetic radiation that is generated when a computer keyboard is tapped is actually pretty easy to capture and decode. Using an oscilloscope and an inexpensive wireless antenna, the Ecole Polytechnique team was able to pick up keystrokes from virtually any keyboard, including laptops — with 95 percent accuracy over a distance of up to 20 meters. Using similar techniques, Inverse Path researchers Andrea Barisani and Daniele Bianco picked out keyboard signals from keyboard ground cables. On PS/2 keyboards, ‘the data cable is so close to the ground cable, the emanations from the data cable leak onto the ground cable, which acts as an antenna,’ Barisani said. That ground wire passes through the PC and into the building’s power wires, where the researchers can pick up the signals using a computer, an oscilloscope and about 0 worth of other equipment. Barisani and Bianco will present their findings at the CanSecWest hacking conference next week in Vancouver. The Ecole Polytechnique team has submitted their research for peer review and hopes to publish it very soon.”

angry tapir writes with this excerpt from Good Gear Guide: “One Laptop Per Child is set to dump x86 processors, instead opting to put low-power Arm-based processors in its next-generation XO-2 laptop with the aim of improving battery life. The nonprofit is ‘almost’ committed to putting the Arm-based chip in the next-generation XO-2 laptop, which is due for release in 18 months, according to Nicholas Negroponte, chairman of OLPC. The XO-1 laptop currently ships with Advanced Micro Devices’ aging Geode chip, which is based on an x86 design.”

From the beginning of the recession in December 2007 through February 2009, 4.4 million people have lost their jobs in the U.S. And for about one in two workers,a software license, a PC or a laptop has also been left behind, often times with sensitive data intact.

Al writes “A new lithium-ion electrode allows batteries to be charged and discharged in 10 seconds flat. Developed by Gerbrand Ceder, a professor of materials science at MIT, it could be particularly useful where rapid power bursts are needed, such as for hybrid cars, but also for portable electronic devices. In testing, batteries incorporating the electrodes discharged in just 10 seconds. In comparison, the best high-power lithium-ion batteries today discharge in a minute and a half, and conventional lithium-ion batteries, such as those found in laptops, can take hours to discharge. The new high rate electrode, the researchers calculate, would allow a one-liter battery based on the material to deliver 25,000 watts, or enough power for about 20 vacuum cleaners.”
