More on the DARPA robot car contest, currently underway, from Scott Ettinger. Read his previous blog for more info.
Today Junior (Stanford’s robotic vehicle) faced the dreaded merge testing at track A. As I described earlier, this test involves dense two way traffic of human driven vehicles on a loop that Junior must continuously merge into and out of by making left turns. Some of the tests here with other robotic vehicles have been very exciting to watch as some have misjudged the traffic and caused mayhem by pulling into traffic with cars directly in front of them. One managed to collide with one of the traffic cars driven by professionals who are very good at getting out of the way (I have watched them avoid many very close calls).

This blog comes to you from Scott Ettinger of our Applications Research Lab. Scott is on-site at the DARPA Urban Challenge, working with the Stanford team to try and win a unique automobile race where there are no drivers. Photos are courtesy of Jan Becker.
George A.F.B. - Victorville California. This once abandoned air force base has been transformed into a busy tent city filled with some of the top technical talent in the world. Super high-tech vehicles – most covered with arrays of cutting-edge laser sensors can be seen around every corner. With the mass of equipment on board, many look like they are designed to explore distant planets. Instead, these vehicles are designed to explore much closer to home on our own city streets. This entire gathering is in fact dedicated to developing cars that drive themselves. It is the pinnacle of years of work by the best robotics experts from around the world.

Intel Research Pittsburgh Lab opened doors today to academia, press and just about anyone in the general Pittsburgh public who wanted to stop by. The open house buzzed with enthusiasm from an estimated nearly 200 attendees about the advancements the lab is making and ideas sparked on potential areas for collaboration.

In this post, I share with you an interview with Jeff Ravencraft who is a technology strategist in Intel’s Communication Technology Lab, where he leads Intel’s effort in USB and Wireless USB. Jeff is also the Chairman and President of the USB Implementers Forum (USB-IF) industry group, Chairman of the Wireless USB Promoters group, and also serves as the USB 3.0 Promoter group chairman.

After our first ray-tracing article, we received numerous comments from consumers and graphics experts alike. One of these mavens (who happens to be an Intel employee from another group, and also an active SIGGRAPH participant) surprised us with an interesting perspective, and we decided to publish it as a separate article. As always, the Intel @ Research blog values the comments made by our readers. We hope to create a rich discussion forum where research topics can be discussed by industry experts and consumers alike. So please join in and contribute!

Hundreds of GigaFLOPs are available in your PC today….in fact, you might even have a TeraFLOP in there. As someone who cut his teeth on a Cray C90 (15 GFLOPS max), this is an intriguing opportunity to dabble; for the latter-day high performance computing programming (whether you’re trying to predict protein structure, price options, or trying to figure out how to thread your game), it is almost too tempting to ignore. However, like a shimmering, unreachable oasis, today’s GPUs offer the promise of all the performance you require, but achieving that goal for all but a few applications (notably, those they were designed for: rasterization)is elusive.

Security and privacy are hot topics to consider when designing pervasive computing systems. Hot is the operative word, because if you compromise security or privacy, you’ll likely upset a lot of people, and a heated discussion will ensue. I doubt many people would disagree with this observation. However, in practice, I’ve found that attention to security as well as interpretations of privacy vary a great deal.

Let’s take this opportunity to talk about wireless co-existence, an issue that begins to draw broad attention in the mobile communication industry, an issue that will help shape the system and architecture design of mobile device and infrastructure for years to come.

The title seems rather provocative, but PC Perspective seems to think that this is a definite possibility. But is it…? I’d like to explore the current state-of-the-art in real time ray-tracing, based on what has been shown at last months Intel Developer Forum, where ray-tracing expert Daniel Pohl showed off his port of the Quake IV video game to Intel’s real time ray-tracer. I’ll also explore some future applications of ray-tracing that may make it a very compelling alternative to today’s raster pipeline.

I have been pleased by the attention my blog on choice overload has received. I must admit, I overstated things a bit just to get people talking … and on that count, I clearly succeeded.
In my present blog, I’d like to respond to comments on my choice overload blog .. and then discuss how dumb I might be.

I recently had the opportunity to talk with Rob Ennals, the lead researcher on the Mash Maker product, to get an update on how things were going with the evaluation program. Bottom line for Rob and the team was that they were pleasantly overwhelmed by the response to the evaluation program. To date, nearly 7000 people have registered to participate in the evaluation. Rob attributed this response to two primary factors: Slashdot and IDF.

The single most important paper for programming language designers to read came out in 2000. It wasn’t written by a computer scientist, mathematician, or physical scientist. It was written by a couple professors studying social psychology:
