igrigorik writes "In the short span of just a couple of years, the Ruby VM space has evolved to more than just a handful of choices: MRI, JRuby, IronRuby, MacRuby, Rubinius, MagLev, REE and BlueRuby. Four of these VMs will hit 1.0 status in the upcoming year and will open up entirely new possibilities for the language — Mac apps via MacRuby, Ruby in the browser via Silverlight, object persistence via Smalltalk VM, and so forth. This article takes a detailed look at the past year, the progress of each project, and where the community is heading. It's an exciting time to be a Rubyist."

Hugh Pickens writes "The Charleston Daily Mail reports that machinist Mike Daugherty built his son a working cannon for his birthday — not a model — a real working cannon. 'It looks like something right out of the battle at Gettysburg,' says Daugherty. The 700 pound cast iron and steel howitzer, designed to use comparatively small explosive charges to propel projectiles at relatively high trajectories with a steep angle of descent, has a 4-inch gun barrel that is 36 inches long mounted on a wooden gun carriage with two 36- inch diameter wheels and took Daugherty about two weeks to build at a cost of about $6,000. 'I've always been interested in the Civil War and cannons, so I thought it would be a good gift,' says Daugherty's 11-year old son Logan. Daugherty said he is not worried about the federal government coming to get his son's cannon because he spoke to the federal Bureau of Alcohol, Tobacco, Firearms and Explosives and found it is legal to own such a cannon because it does not use a firing pin and is muzzle loaded so the government does not consider the weapon a threat. Two days after the family celebrated Logan's 11th birthday, father and son offered a field demonstration of the new cannon on top of a grassy hill overlooking Fairmont, West Virginia and on the third try, the blank inside the barrel went boom and a cannon was born. For a followup they popped a golf ball into the gun barrel, lit the fuse, and watched the golf ball split the sky and land about 600 yards away. 'Any rebels charging up this hill would be in trouble with a cannon like this at the top,' Logan says."

Hugh Pickens was one of several readers to let us know that, according to a NY Times story, the 89-year-old Ray Bradbury hates the Internet. But he loves libraries, and is helping raise $280,000 to keep libraries in Ventura County open. "Among Mr. Bradbury's passions, none burn quite as hot as his lifelong enthusiasm for halls of books. ... 'Libraries raised me,' Mr. Bradbury said. 'I don't believe in colleges and universities. I believe in libraries because most students don't have any money. When I graduated from high school, it was during the Depression and we had no money. I couldn't go to college, so I went to the library three days a week for 10 years.' ... The Internet? Don't get him started. 'The Internet is a big distraction,' Mr. Bradbury barked... 'Yahoo called me eight weeks ago,' he said, voice rising. 'They wanted to put a book of mine on Yahoo! You know what I told them? "To hell with you. To hell with you and to hell with the Internet." It's distracting. It's meaningless; it's not real. It's in the air somewhere.'"

Two recent announcements lend support Sony's promise to bring a stronger game lineup to its PSP console this year. Tekken 6, which was already known to be in development for the 360 and PS3, has now been confirmed for the PSP as well. "... the portable version of the game is set to release alongside the other console iterations and will pack additional stages, content, items, and an ad-hoc multiplayer mode using 'original' and 'fan favorite characters.'" We've also found out that Soul Calibur: Broken Destiny is being specifically designed for the PSP, and will include "arcade, versus, and survival modes, as well as a character creation mode." In addition, 1Up reports on the latest rumors surrounding a redesigned PSP (possibly called the "Go!"), which they say will be unveiled later this year at E3.

tuna writes "A real-world test by the Dutch province of Zeeland (a very windy place) demonstrates that small windmills are a fundamentally flawed technology (PDF of tests results in Dutch, English summary). Twelve much-hyped micro wind turbines were placed in a row on an open plain. Their energy yield was measured over a period of one year (April 1, 2008 — March 31, 2009), the average wind velocity during these 12 months was 3.8 meters per second, slightly higher than average. Three windmills broke. The others recorded ridiculously low yields, in spite of the optimal conditions. It would take up to 141 small windmills to power an average American household entirely using wind energy, for a total cost of 780,000 dollars. The test results show clearly that energy return is closely tied to rotor diameter, and that the design of the windmill hardly matters."
