theodp writes "Admit it, IT is ingenious. Also, IT is surprisingly effective for certain uses, including real cops and mall cops. And if you tried IT, you probably smiled to yourself. So why all the Segway hate? Paul Graham looks into The Trouble with the Segway and offers a hypothesis about what prompts people to shout abuse at Segway riders: 'You look smug. You don't seem to be working hard enough.' Not that someone riding a motorcycle is working any harder, adds Graham, but because he's sitting astride it, he appears to be making an effort. When you're riding a Segway you're just standing there. Make a version that doesn't look so easy for the rider — perhaps resembling skateboards or bicycles — and Segway just might capture more of the market they hoped to reach."

firthisaword writes "I will be teaching an enrichment programming course to 11-14 year old gifted children in the Spring. It is meant as an introduction to very basic programming paradigms (conditions, variables, loops, etc.), but the kids will invariably have a mix of experience in dealing with computers and programming. The question: Which programming language would be best for starting these kids off on? I am tempted by QBasic which I remember from my early days — it is straightforward and fast, if antiquated and barely supported under XP. Others have suggested Pascal which was conceived as an instructional pseudocode language. Does anyone have experience in that age range? Anything you would recommend? And as a P.S: Out of the innumerable little puzzles/programs/tasks that novice programmers get introduced to such as Fibonacci numbers, primes or binary calculators, which was the most fun and which one taught you the most?" A few years ago, a reader asked a similar but more general question, and several questions have focused on how to introduce kids to programming. Would you do anything different in teaching kids identified as academically advanced?

Hugh Pickens writes "Time Magazine reports on a $4 million US Army contract to begin developing 'thought helmets' to harness silent brain waves for secure communication among troops that the Army hopes will 'lead to direct mental control of military systems by thought alone.' The Army's initial goal is to capture brain waves with software that translates the waves into audible radio messages for other troops in the field. 'It'd be radio without a microphone,' says Dr. Elmar Schmeisser, the Army neuroscientist overseeing the program. 'Because soldiers are already trained to talk in clean, clear and formulaic ways, it would be a very small step to have them think that way.' The key challenge will be to develop software able to pinpoint speech-related brain waves and pick them up with a 128-sensor array that ultimately will be buried inside a helmet. Scientists deny charges that they're messing with soldiers' minds. 'A lot of people interpret wires coming out of the head as some sort of mind reading,' says Dr. Mike D'Zmura. 'But there's no way you can get there from here.' One potential civilian spin-off: a Bluetooth Helmet so people nearby can't hear you when you talk on your cell phone."

Roland Piquepaille writes "According to ICT Results, an EU-funded project named Embounded 'has achieved the twin, and apparently contradictory, goals of making embedded systems both smarter and tougher.' One example is the robuCAB, a '4 seat automated people mover' developed by a French company and built from a 4 wheel-drive electric chassis with on-board PC. This autonomous vehicle follows the curb and carries several embedded systems, with one camera on the path edge, another device tracking the angle and direction of the curb, while others control the gearing and acceleration. robuCABs are not totally independent. They move over pre-defined circuits which contain a series of sensors below the ground. But read more for additional references and a picture of two robuCABs on the road."

The growing popularity of Massively Multiplayer games has brought the issue of ownership rights in virtual worlds, and the appropriateness of what is called 'real money transfer' (RMT) into an increasingly public light. The success of the company IGE, as well as the launch of Sony Online Entertainment's 'Station Exchange' service would seem to indicate that RMT is now an acceptable part of Massive gaming. The well-known auction site eBay has recently made a policy decision that may throw these assumptions into a different light. Following up on a rumour that's been going around I spoke today with a media representative for the company, who confirmed that eBay is now delisting all auctions for 'virtual artifacts' from the site. This includes currency, items, and accounts/characters; not even the 'neopoints' used in the popular Neopets service is exempt from this decision. Read on below for the company's rationale for this decision, and a few words on the impact this could have on future RMT sales.

symbolset notes that The Register is reporting that PCI SIG has released version 2.0 of the PCI Express base specification: "The new release doubles the signaling rate from 2.5Gbps to 5Gbps. The upshot: a x16 connector can transfer data at up to around 16GBps." The PCI-SIG release also says that the electromechanical specification is due to be released shortly.

The self-assembly kit is part of what they call the Fab@Home project — they hope it will spark development of rapid prototyping for the consumer market in the same way the Altair 8800 did for personal computing in seventies." Here is a video showing a completed machine constructing a silicone bulb (16-MB WMV).
Update: 01/10 04:02 GMT by KD : The developers of this kit are at Cornell, not Carnegie Mellon University as the original post erroneously stated.

An anonymous reader writes "Space.com is reporting that NASA has decided to use the metric system for its new lunar missions. NASA hopes that metrication will allow easier international participation and safer missions. The loss of the Mars Climate Orbiter was blamed on an error converting between English units and metric units. 'When we made the announcement at the meeting, the reps for the other space agencies all gave a little cheer,' said a NASA official."

mytrip writes to mention a Financial Times article detailing Microsoft's apparent interest in Yahoo!, and Yahoo!'s rude reaction to their interest. From the article: "The fight is on between the three internet search titans, after Yahoo's Terry Semel laid down the gauntlet to Microsoft saying the software giant's recently elevated ambitions in the search arena were a lost cause. 'My impartial advice to Microsoft is that you have no chance. The search business has been formed,' he said in an interview with the New Yorker's Ken Auletta."
