One of the coolest uses for this was maneuvering around Microsoft Virtual Earth using your hands. Microsoft showed off two methods, the first using a projector that gleams down on a table top. Using your hands, you can pull the map around, and zoom in and out by pinching in a similar fashion to what Apple has done with the iPhone.

At Microsoft, Ozzie has led the company's "Live" initiative, focused on supplementing Microsoft's traditional desktop applications with web-based software and services. But his mission is much broader: to make sure the company's various product groups coordinate their efforts to take advantage of what he termed -- in a now famous memo sent to Microsoft's executive staff on October 28, 2005 -- the "Internet services disruption."
Accomplishing this feat won't be easy, in part because Microsoft is facing challenges on multiple fronts -- technical, business and cultural. New cross-platform technologies threaten to establish a new layer of abstraction that could reduce the importance of the operating system as a software development platform. Emerging business models -- such as open-source software and "free" advertising-supported applications -- threaten to undermine the economic basis for Microsoft's longstanding success. And while Microsoft's size provides it with enormous resources, some wonder whether this may make it difficult for the company to remain agile enough to break from its past successes and address these new challenges.
Back in February we reported that Intel's Douglas Carmean, new Chief Architect of their Visual Computing Group (VCG) in charge of GPU development at Intel, had been touring universities giving a presentation called "Future CPU Architectures -- The Shift from Traditional Models". Since then he's added a few more major university stops, and now the feared B3D ninjas have caught up with him. Our shadow warriors have scored a copy of Carmean's presentation, and we've selected the juicy bits for your enjoyment and edification regarding the showdown that Intel sees as already underway between CPU and GPU makers.
According to Clyde Stubbs, CEO and Founder, HI-TECH Software, the new methodology, cakked Omniscient Code Generation (OCG), overcomes many of the pitfalls of conventional compilers that frequently miss inconsistent calling conventions, variable declarations, and redundant code because they compile each module independently and separately.
"OCG optimizes the size of each pointer variable, based on its usage, eliminates the need for many non-standard C qualifiers and compiler options," he said, "and produces more optimal interrupt context switching code, and customizes the functionality of library function."
