Supercomputers need super, or at least novel, debugging.

To meet that need, Cray has just agreed to license Australian software start-up Guardsoft's "relative" debugging technology for use in its new DARPA-funded supercomputer.

Relative debugging allows programmers to track bugs that creep into software as it is modified, or ported from one system to another, according to Guardsoft. It does this by comparing the execution of a suspect program with a clean version. This differs from traditional debugging in two ways: First, it compares program variables not with the user's expectations but with another program known to … Read more

When it comes to international quagmires, it would be nice to know if the natives are restless before you send in the cavalry.

Apparently, the U.S. military is not happy with the briefings it gets before being dispatched to police deadly fiascos around the world. So it is underwriting a program that will allow commanders not only to predict events and gauge stability in the countries in which they operate, but also to anticipate and respond to political crises worldwide.

The Defense Advanced Research Projects Agency (DARPA) has awarded Lockheed Martin a contract to develop PRESAGE (Predicting Stability through … Read more

For all the times we saw the likes of KITT and Herbie get themselves around the TV screen under their own steam, there is still something simultaneously unnerving and thrilling about watching a car drive right past you with no one on board--for real. To see a driverless car stop at a busy intersection, wait for a gap in the traffic, and then make a left-hand turn makes the hairs on the back of your neck stand on end.

We were on site yesterday in Victorville, Calif., where 36 teams are participating in the 2007 DARPA Urban Challenge, a contest … Read more

Excitement is building in the world of car tech as the 2007 DARPA Urban Challenge approaches. The event, which is the third and most demanding to date in the DARPA Challenge series, requires driverless vehicles to perform mock military supply missions completely autonomously. Over a 60-mile course, the robotic cars will be required to merge into moving traffic, navigate traffic circles, negotiate busy intersections, and avoiding obstacles. Thirty-five teams will compete in the Grand Challenge semifinals taking place between October 26 and 31, with 20 vehicles going on to compete in the final race on November 3. Check out our … Read more

"What the #*%^?" is a common question heard every year from hundreds of bobbing heads attempting the famous Alcatraz swim across San Francisco Bay; arms and legs flail furiously, but it seems they're no closer to the beach.

The government has an explanation for this swimming phenomenon: You suck!

It's spelled out in this month's Popular Mechanics. "Humans are terrible swimmers, converting roughly 3 percent of their kicks, strokes and general underwater exertions into forward motion. We can boost our efficiency to 10 percent by adding fins, but dolphins, by comparison, can turn 80 percent … Read more

After a two-year break since its last robot race, the U.S. government's Defense Advanced Research Projects Agency will hold the semifinals of its Urban Grand Challenge from October 26 through October 31.

Teams are expected to descend on the dusty town of Victorville, Calif., to race their modified robotic cars through a mock city at the former George Air Force Base. The winner of first place will take home $2 million; second place, $1 million and third, $500,000.

CNET News.com reports on and posts photos of Caltech's entrant for the DARPA Urban Challenge. This Ford E-350 van, named Alice, is rigged with GPS, LIDAR, and other sensors, the data from which is processed by Caltech's custom programming. The goal for Alice is to negotiate an urban course designated by DARPA without a driver. This Urban Challenge is a new twist on DARPA 2005 Grand Challenge, which ran through the desert. In the Urban Challenge, cars will have to follow basic street rules, like staying in their lanes and obeying traffic signs and signals. The race … Read more

Oh ye of little faith, behold: Pratt & Whitney Rocketdyne has successfully tested a sub-scale combustor for a dual-mode ramjet engine that could power the DARPA-financed Falcon HTV-3X hypersonic cruiser to Mach 6 and beyond. Dual-mode because the engine can function both at subsonic speeds and then kick up to supersonic scramjet speeds (greater than Mach 5).

By contrast, one of the fastest conventional Air Force jets--the SR-71 Blackbird--does a tortoise-paced Mach 3.4.

The engine technology was developed for Lockheed Martin's Falcon Combined-Cycle Engine Technology (FaCET) program. The goal is to develop hypersonic technologies that would … Read more

Every morning, generals across the world wake up and wonder what the enemy is thinking. Well, it depends: Are they "chicken" or "Rambo"?

That's the bottom line for a new DARPA-funded software program based on the child's game "Capture the Flag." The strategy-predicting software BEE (Behavioral Evolution and Extrapolation) is designed to anticipate enemy actions and deceptions--ideally in time to do something about them.

BEE works by replacing large numbers of combatants with digital avatars on a simulated battlefield, assigning them individual personalities (e.g., alive enemy, injured friendly), factoring in beliefs … Read more
