The US Swim Team's Secret Weapon, Science 180

Hugh Pickens writes "When American Swimmer Margaret Hoelzer goes for the gold tonight in the 200-meter backstroke, part of her success will be due to a new system developed by Tim Wei, a mechanical and aerospace engineer at Rensselaer Polytechnic Institute, that uses fluid dynamics to study human movement allowing scientists and coaches to study how fast and hard a swimmer pushes the water as he moves through it. 'Wei uses a tracking technique called digital particle image velocimetry, commonly used to measure the flow of small particles around an airplane or small fish or crustaceans in water.' Wei filtered compressed air in a scuba tank through a porous hose to create bubbles about a tenth of a millimeter in diameter. When an athlete swims through a sheet of bubbles that rises from the pool floor, a camera captures their flow around the swimmer's body and the images show the direction and speed of the bubbles, which Wei then translates into the swimmer's thrust using software that he wrote."

Microsoft Blesses LGPL, Joins Apache Foundation 425

Penguinisto writes "According to a somewhat jaw-dropping story in The Register, it appears that Microsoft has performed a trifecta of geek-scaring feats: They have joined the Apache Software Foundation as a Platinum member(at $100K USD a year), submitted LGPL-licensed patches for ADOdb, and have pledged to expand their Open Specifications Promise by adding to the list more than 100 protocols for interoperability between its Windows Server and the Windows client. While I sincerely doubt they'll release Vista under a GPL license anytime soon, this is certainly an unexpected series of moves on their part, and could possibly lead to more OSS (as opposed to 'Shared Source') interactivity between what is arguably Linux' greatest adversary and the Open Source community." (We mentioned the announced support for the Apache Foundation earlier today, as well.)

Mozilla and Google — Exchange Killers At Last? 336

phase_9 writes "The latest version of Mozilla Thunderbird may still only be in beta but already the user community have started creating an extensive set of viable Exchange killers. One such example is the latest mashup between Thunderbird and Google Calendars, providing bi-directional syncing of calendar information from both the client and internet. How long will it be before open-source software can provide a complete, accessible office suite for a fraction of the cost that Microsoft current imposes?"

adamlazz writes "With an explosion of online video content on sites like YouTube and Google Video, Bill Gates believes that the Internet will revoloutionize the television within the next 5 years. 'I'm stunned how people aren't seeing that with TV, in five years from now, people will laugh at what we've had,' Gates told business leaders and politicians at the World Economic Forum. "
