The first unofficial implementation of the PC-controller API has just been posted. Using the SDK, the 17 servos that give the robot its mobility can be remote controlled by the PC via WiFi or bluetooth, and their current position can be retrieved several times per second. This unique feature will allow robot fans to go beyond simple performance of motion sequences or low-level gyro-based motion correction and develop algorithms that involve feedback control and AI.”

Frank W. Zametti has written an article and accompanying webapp that shows simple usage of Ajax (Asynchronous Javascript + XML), specifically within a Struts application. Mr. Zametti walks through how Ajax is working, why it might be used, and how to apply it in a number of interesting usages of Ajax, including a sortable table and an RSS feed parser, with full code.

[/.] An anonymous /. reader asks: “Slashdot recently covered a story that DARPA
would significantly cut CS research.
When I was completing graduate work in AI, the ‘baby bootstrap’ was considered the holy grail of military applications. Simply put, the ‘baby bootstrap’ would empower a computing device to learn like a child with a very good memory. DARPA poured a small fortune into the research. No sensors, servos or video input – it only needed terminal I/O to be effective. Today the internet could provide a developmental database far beyond any testbed that we imagined, yet there has been no significant progress in over 30 years. MindPixels and Cycorp seem typical of poorly funded efforts headed in the wrong direction, and all we hear from DARPA is autonomous robots. NIST seems more interested in industrial applications. Even Google
is remarkably void of anything about the ‘baby bootstrap’. What went wrong? Has the military really given up on this concept, or has their research moved to other, more classified levels?”

Now, imagine a single technology combining the advantages of photonics and electronics. This Stanford University report says a new technology can do it: plasmonics. (For more about plasmons, read this Wikipedia article.) Theoretically, it is possible to design plasmonic components with the same materials used today by chipmakers, but with frequencies 100,000 times greater than the ones of current microprocessors. There is still a challenge to solve before getting plasmonic chips. Today, plasmons can only travel a few millimeters before dying, while today’s chips are typically about a centimeter across. Read this overview for more details and references about plasmonics, and to discover why it’s one possible future for chips’ circuitry.”
