Submission + - First production flying car to be built

Submitted by Tookis on Sunday July 22, 2007 @05:58PM

Tookis writes: The first production flying car is being designed to be a vertical take-off and landing vehicle. The flying car, under production for consumer purchase, is called the M200G. Its cost to customers is estimated to be at least $90,000 (in U.S. dollars). The M200G uses eight low-emission Rotapower engines (Wankel rotary engines, produced by Freedom Motors). Its advanced cooling system allows it to be a fairly lightweight vehicle. Its projected cruising speed is about 50 miles per hour at about 10 feet off the ground. A Mark II version under development will have a cruising speed of 300MPH at an altitude of more than 6 miles. http://www.itwire.com.au/content/view/13627/1066/

First "Real" Benchmark for PostgreSQL 275

Posted by ScuttleMonkey on Monday July 09, 2007 @04:15PM from the waiting-for-the-opportune-moment dept.

anticlimate writes "A new benchmark published on SPEC shows PostgreSQL's performance approaching that of Oracle's and surpassing or on par with MySQL (however the test-hardwares of the other DB systems are somewhat different). The test was put together by PostgreSQL's core developers working at Sun. They certainly are not unbiased, but this is the first 'real' benchmark with PostgreSQL — according to Josh Berkus's blog. The main difference compared to earlier benchmarks (and anecdotes) seems to be the tuning of PostgreSQL."

berberine writes: "Recent research suggests the obvious: that building an undifferentiated network requires far more capacity than one in which traffic is prioritized, throttled, and controlled. But when AT&T researchers are involved in writing the paper in question [pdf], the results seem a bit more sinister. Is the research just another attempt by a major backbone Internet operator to justify a non-neutral Internet?"

StaffInfection writes: "The NASA Dawn mission launch has been slipped to September 15th to begin its journey to the Asteroid belt. Dawn will orbit the two largest asteroids — Vesta and Ceres, and flyby several other smaller asteroids. The Phoenix mission to Mars, the resurrected twin lander to the ill-fated Mars Polar Lander (MPL), remains scheduled for a launch between August 3rd and August 20th, weather and systems permitting. Phoenix will execute the Mission profile of MPL — land at a high martian latitude to study surface morphology, the atmosphere and soil samples with a keen interest in water content. Link to the NASA Dawn announcement and related Phoenix links is located at http://www.nasa.gov/mission_pages/dawn/news/HQ_071 50_Dawn_postpone_Sep.html."
