From Engadget: 'Microsoft just showed us a pair of 3D games running on its ASUS Windows Phone prototype and built with its brand new XNA Game Studio 4.0 9. The two titles are The Harvest, a good looking touch-controlled dungeon crawler with destructible environments, being developed by Luma Arcade; and Battle Punks. Microsoft spoke to the ease of its Direct3D development platform, which was built by the same folks responsible for the first-gen Xbox. What we saw of The Harvest was built in "two or three weeks," mostly from scratch, and folks who've already built games for XNA in VisualStudio shouldn't have much trouble with a port from the sound of things: "very, very easy," said Microsoft. Right now developers can do their testing in Windows, but there should be a Windows Phone 7 Series emulator out for devs eventually.'"

Hugh Pickens writes "When the wind is blowing, it is usually the cheapest peaking power available. However utilities need consistent always-on power from large, cheap coal and nuclear power plants that are the backbone of the electric grid. Wired reports that operators are looking at Compressed Air Energy Storage (CAES) using abandoned mines and sandstones of the Midwest to store compressed-air. This converts the intermittent motions of the air into a steady power source by using it to run air compressors to pump air into an underground cave where it's stored under pressure. The first CAES plant in the United States actually went online in McIntosh, Alabama in 1991 where engineers created a geological pocket 900 feet long and up to 238 feet wide in a dome by pumping water into it to dissolve the rock salt. When the (briny) water was pumped back out, the salt resealed itself and they had an air-tight container."

AT&T customers (iPhone users notably among them) have seen some wireless congestion in recent months; Brough Turner thinks the trouble might be self-inflicted. According to Turner, the poor throughput and connection errors can be chalked up to "configuration errors specifically, congestion collapse induced by misconfigured buffers in their mobile core network." His explanation makes an interesting read.
