On the matter of new hardware support, there's open-source driver support for Intel Broadwell and AMD Radeon R9 290 'Hawaii' graphics. NFTables will eventually replace IPTables; the multi-queue block layer is supposed to make disk access much faster on Linux; HDMI audio has improved; Stereo/3D HDMI support is found for Intel hardware; file-system improvements are on the way, along with support for limiting the power consumption of individual PC components."
dcblogs writes "One year ago this month, the U.S. Department of Energy announced a $120 million plan to develop a technology capable of radically extending battery life. 'We want to change the game, basically,' said George Crabtree, a senior scientist at Argonne National Laboratory and a physics professor who is leading the effort. The goal is to develop a battery that can deliver five times the performance, measured in energy density, that's also five times cheaper, and do it in five years. They are looking at three research areas. Researchers are considering replacing the lithium with magnesium that has two charges, or aluminum, which has three charges. Another approach investigates replacing the intercalation step with a true chemical reaction. A third approach is the use of liquids to replace crystalline anodes and cathodes, which opens up more space for working ions."
Rambo Tribble writes "The BBC reports on efforts at Sydney University, where researchers have had excellent success herding dairy cows with robots. By designing the robots to move smoothly, they have kept the cows moving without stressing them. From the video, one can see the animals seem not to interpret the machine as any threat. 'The robot could also cut down the number of accidents involving humans on farms. Most dairy farmers in Australia use quad bikes to round up their cattle and they are one of the leading causes of injury. The team hopes that by using the robot to do the job instead, accident rates could fall.'"
Lucas123 writes "Autonomous robots programmed to scan city streets with thermal imaging and robotic equipment carriers created to aid in transporting ammunition and other supplies will likely outnumber U.S. troops in 10 years, according to robotic researchers and U.S. military officials. 5D Robotics, Northrop Grumman Corp., QinetiQ, HDT Robotics and other companies demonstrated a wide array of autonomous robots during a display at Ft. Benning in Georgia last month. The companies are already gaining traction in the military. For example, British military forces, use QinetiQ's 10-pound Dragon Runner robot, which can be carried in a backpack and then tossed into a building or a cave to capture and relay surveillance video. 'Robots allow [soldiers] to be more lethal and engaged in their surroundings,' said Lt. Col. Willie Smith, chief of Unmanned Ground Vehicles at Fort Benning, Ga. 'I think there's more work to be done but I'm expecting we'll get there.'"
