I'm told Vernor Vinge has just released a new short story," Synthetic Serendipity". It's a companion piece to his 2002 short ,"Fast Times at Fairmont High". If you liked one, you'll probably like the other. The cheat sheet version can be found here. The story deals with good, fun stuff like ubiquitous computing, consensus reality, and pervasive localizer nets. If you find any of that compelling, you might want to check out the rest of the magazine, "IEEE Spectrum Online". It's good. Want more? There's a thread on Slashdot, which grapples with these topics in that uniquely Slashdot way. Enjoy.
