Submission Setting up a big, one day WiFi network? 4

FurryFeet writes: "I work for a medum size K-12 school and have been notified that in a few weeks we'll have a big training event for teachers. We're expecting about 50 teachers to all bring in their laptops for a full-day training session; they'll all need internet access to do the work. I though I'd just set up a couple of Wi-Fi routers and call it a day, but after googling a bit I bumped into the "Wi-Fi at conferences problem"; namely, there is not a good and easy way to give 50 people a great Wi-Fi connection simultaneously. This is a one-day event, so I don't have a lot of budget. Should I just explain the situation and install a bunch of Ethernet cables? Is there any other way to set up this network that won't cost thousands of dollars?"

Hacked iRobot Uses XBox Kinect To See World 124

kkleiner writes "A student at MIT's Personal Robotics Group is going to put Microsoft's Kinect to a good use: controlling robots. Philipp Robbel has hacked together the Kinect 3D sensor with an iRobot Create platform and assembled a battery-powered bot that can see its environment and obey your gestured commands. Tentatively named KinectBot, Robbel's creation can generate some beautifully detailed 3D maps of its surroundings and wirelessly send them to a host computer. KinectBot can also detect nearby humans and track their movements to understand where they want it to go." In related but less agreeable news, "Dennis Durkin, who is both COO and CFO for Microsoft's Xbox group, told investors this week that Kinect can also be used by advertisers to see how many people are in a room when an ad is on screen, and to custom-tailor content based on the people it recognizes."

If it has syntax, it isn't user friendly.
