Steve Tarzia writes "A research group at Northwestern University and University of Michigan has released open-source display power-management software that uses a new user presence detection technique. The goal is to shut off the display immediately when the user leaves the computer rather than using slow and error-prone mouse/keyboard activity timeouts. Surprisingly, the mic and speakers of many laptop computers are sensitive to ultrasonic frequencies. Those frequencies can be used to silently probe the laptop's physical environment. This software is based on research published at the UbiComp2009 conference. A Windows binary and source code for Windows and Linux are available for download."

Turbine is making their MMO as accessible as possible, and that includes making players who don't pay anything as happy as possible. Subscriptions are up 40 percent. Ars explores how free can be very profitable."

An anonymous reader writes "Starting next July, every person in Finland will have the right to a one-megabit broadband connection, according to the Ministry of Transport and Communications. Finland is the world's first country to create laws guaranteeing broadband access. The Finnish people are also legally guaranteed a 100Mb broadband connection by the end of 2015."

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.

Barence writes "Acer today revealed the world’s first 3D laptop, the Acer Aspire 5738PG, which will launch alongside Windows 7 on October 22. It uses a combination of software and specially coated glass on the 15.4in screen, along with a standard set of polarised glasses. Initial impressions were a bit iffy, and whether anyone actually needs a 3D laptop is another question entirely, but we'll find out this month."

ChiefMonkeyGrinder writes "Once Sebastian Nyström laid out the logic of moving to open source, there was very little resistance within Nokia to doing so. I think that's significant; it means that, just as the GNU GPL has been tested in various courts and found valid, so has the logic behind open source — the openness that allows software to spread further, and improve quicker, for the mutual benefit of all. That idea is also increasingly accepted by hard-headed business people: it's become self-evident that it's a better way."

Writing in the ribbonfarm.com blog, Venkatesh Rao uses The Office to explain and illustrate a theory of management he calls the Gervais Principle (after the TV series's creator). Taking off from Hugh MacLeod's cartoon laying out a corporate hierarchy in layers of Sociopaths, the Clueless, and Losers, Rao riffs on and updates the Peter Principle, in these terms: "Sociopaths, in their own best interests, knowingly promote over-performing losers into [clueless] middle-management, groom under-performing losers into sociopaths, and leave the average bare-minimum-effort losers to fend for themselves." Don't know about you, but this analysis suddenly makes sense of much that mystified me in my sojourn in corporate America.
