Philips Electronics, a Netherlands-based company, has come up with a device designed to protect day traders from emotionally based trading decisions. The Rationalizer measures your galvanic skin response and lets you know when you are under stress. An online trader can then take a "time-out, wind down and re-consider their actions," according to the company. This may have come too late for us, but at least future generations won't have to live through the horror of angry day trading.

Hugh Pickens writes "Apple co-founder Steve Wozniak is going back to work as chief scientist at Fusion-io, a start-up company that tweaks computers to let them tap vast amounts of storage at very quick rates. In the early days of Apple, Wozniak stood out as one of Silicon Valley's most creative engineers, demonstrating a knack for elegant computer designs that made efficient use of components and combined many features into a cohesive package and Wozniak will do similar work at Fusion-io, although this time with larger server computers and storage systems rather than PCs. 'I have a pretty quiet life, and I like to watch technology evolve,' says Wozniak. 'In this case, I like the people and the product, and said I would like some greater involvement.'"
