Some notable improvements over the initial beta release include 'reduced memory usage, improved text rendering and a 60% install size reduction on Android (from around 43 MB to 17 MB).' Mozilla also makes mention that 'actions like panning and zooming are faster and smoother, and page load times are reduced from our previous beta. On Android 2.2, we're now around 25% faster on the SunSpider JavaScript benchmark than the stock browser.' A future beta release will enable GL acceleration, which should further improve the performance of the browser."

Valve announced yesterday that their extension of Steam, called Steam Cloud, will launch later this week with the Left 4 Dead demo. Steam Cloud is "a set of services for Steam that stores application data online and allows user experiences to be consistent from any PC." We discussed an early announcement for it back in May. Valve adds that "Steam Cloud will be available to all publishers and developers using Steam, free of charge, and Valve will add Cloud support to its back catalog of Steam games. Cloud services are compatible with games purchased via Steam, at retail, and other digital outlets."

An anonymous reader writes "The BBC reports on a proposal to use RFID and wi-fi to track students wherever they go on campus: 'Battery-powered RFID tags are placed on an asset and they communicate with at least three wireless access points inside the network to triangulate a location.' At The Wireless Event in London, 'Marcus Birkl, head of wireless at Siemens, said location tracking of assets or people was one of the biggest incentives for companies, hospitals and education institutions to roll out wi-fi networks.' The article points out that integration of RFID and wi-fi raises the possibility that RFID can be used for remote surveillance."
