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."

olyar writes "I worked for an internet start-up last year and during the 'we have plenty of money' phase, a lot of server hardware was purchased. Eight months later, there is very little money, but we're still plugging along — using only a fraction of the hardware. We just cleared out a co-lo and I now have a stack of 17, 1U servers in my garage. Each of those has 2 servers, each of which is a 2-processor, dual-core box with 8 GB of RAM. Add that up and I have 136 processors and 272 GB of RAM with nothing to do. The IT guy in me thinks that's a waste of FLOPS. The wanna-be businessman in me thinks its probably a waste of money as well. So I've been brainstorming ways to put all of that power to good use. Any ideas?"

Presto Vivace writes to tell us that CIO has an interesting article about customer "gag orders" that some ERP vendors are trying to impose contractually. "The effect: customers will be prevented from working with peers and others in the software company's "ecosystem" to help with technical issues or compare pricing options. 'In addition,' Wang adds, 'the customer now lacks the proper checks and balances in pressuring a vendor to deliver on promised capabilities or address severe security issues, and cannot go to the media as a last resort, if needed.'" What other questionable practices (and potential solutions) have others had to work with?

Iain writes "I'm a teacher at a British 'City Academy' (ages 11-19) that is going to move into a new building next year. Management is deciding now on the IT that the students will use in the new building, as everything will be built from scratch. Currently, the school has one ICT suite per department, each containing about 25-30 PCs. My issue with this model is that it means these suites are only rarely used for a bit of googling or typing up assignments, not as interactive teaching tools. The head likes the idea of moving to a thin client solution, with the same one room per department plan, as he see the cost benefits. However, I have seen tablet PCs used to great effect, with every single classroom having 20-30 units which the students use as 'electronic workbooks,' for want of a better phrase. This allows every lesson to fully utilize IT (multimedia resources, Internet access, instant handout and retrieval of learning resources, etc.) and all work to be stored centrally. My question is: In your opinion, what is the best way for a school to use IT (traditional computer lab, OLPCs, etc.) and what hardware is out there to best serve that purpose? Fat clients for IT/Media lessons and thin client for the rest? Thin client tablets? Giving each student a laptop to take home? Although, obviously, cost is an issue, we have a significant budget, so it should not be the only consideration."

ubergamer1337 writes "Next semester I will be participating in a college study abroad program known as Semester at Sea. The gist of it is that over four months 600ish students sail around the world on a converted cruise ship, visiting diverse port cities while taking classes when we are between ports. Debates about its educational merit aside, my internet options while I will be at sea will be severely limited. We get just 100 minutes of internet access for the entire voyage, and once thats gone the only internet access we have is a university email address, which is limited to messages under a megabyte with no attachments. I have been pondering different ways to staying in contact with friends and family back at home without running to an internet cafe in every port, and I have already decided that I want to set up a blog that can be updated by email, but I wanted to ask the collective wisdom of Slashdot if anyone knows of any other ways to transmit more then just your standard message through email. Some things I would be particularity interested in being able to figure out would be a way to send photos (encode them as text?), and a way to get Wikipedia pages etc. emailed to me."

Sportsqs writes "When Nikola Tesla got creative with transformers and driver circuits at the turn of the 20th century he probably had no idea that others would have so much fun with his concepts over a hundred years later. One such guy is an Australian named Peter who runs a website called TeslaDownUnder, which showcases all his wacky Tesla ways, or rather electrickery, as Peter calls it." Very cool stuff, I wish I would have had something like this to protect my comic books from my little brother when I was a kid.

Destructoid is running an opinion piece looking at the state of the survival-horror genre in games, suggesting that the way it has developed over the past several years has been detrimental to its own future. "During the nineties, horror games were all the rage, with Resident Evil and Silent Hill using the negative aspects of other games to an advantage. While fixed camera angles, dodgy controls and clunky combat were seen as problematic in most games, the traditional survival horror took them as a positive boon. A seemingly less demanding public ate up these games with a big spoon, overlooking glaring faults in favor of videogames that could be genuinely terrifying." The Guardian's Games Blog has posted a response downplaying the decline of the genre, looking forward to Ubisoft's upcoming I Am Alive and wondering if independent game developers will pick up where major publishers have left off.

Banquo writes "I have a friend who has a small datacenter (SQL/Mail/IIS/File Repository ... 5 or 10 servers) and he was saying that his boss wants to see some kind of 'visual display of changing metrics' — Net/server/sql stats with moving lines and graphs and pretty colors. Basically they want something to display on a big LCD panel that will give a tiny bit of 'Wow' factor to customer visits. Back in my datacenter days I saw a million packages to do this stuff, but I was always blessed with an IT budget for metrics/monitoring. Can anyone suggest a free/cheap package that will make pretty moving pictures, moving lines, graphs, etc. from server/net stats? There's no worry about actually using this for real data tracking or metrics purposes. He has a pretty robust log/alert/metrics setup, but command line is a little too dry for marketing purposes. I jokingly suggested he just use a looped flash animation but he actually does want stats that are coming from and reflect his environment. Anyone know of any cheap or free data center stats/metrics 'Eye Candy' software out there?" Better yet, can you think of any particularly interesting ways to display that sort of information?

hcg50a writes "NASA has successfully tested the first deep space communications network modeled on the Internet. Working as part of a NASA-wide team, engineers from NASA's Jet Propulsion Laboratory in Pasadena, CA, used software called Disruption-Tolerant Networking, or DTN, to transmit dozens of space images to and from a NASA science spacecraft located about 20 million miles from Earth. The store-and-forward protocol was designed by NASA in consultation with Vint Cerf. Here's a discussion from last July before the test began."

jddeluxe writes "In an article in today's NY Times, John Doerr of Kleiner-Perkins proffered up Bill Joy's name when queried by Barack Obama for a recommendation for the position of Chief Technology Officer of the Unites States which Obama has promised to create and that the country is overdue to have. I think that's a brilliant idea, and while you're at it, have the FCC report to him as well, why don't you?" If Bill is unavailable, I'll throw my hat in the ring, although I'm holding out for Secretary of Tubes.

An anonymous reader writes "BD+, the Blu-ray copy protection system that was supposed to last 10 years, has now been solidly broken by a group of doom9 researchers. Earlier, BD+ had been broken by the commercial company SlySoft." Someone from SlySoft posts a hint early in the thread, but then backs off for fear of getting fired. The break is announced on page 15.

vitamine73 writes "At 9 a.m. next Sunday, six computer programs — 'artificial conversational entities' — will answer questions posed by human volunteers at the University of Reading in a bid to become the first recognized 'thinking' machine. If any program succeeds, it is likely to be hailed as the most significant breakthrough in artificial intelligence since the IBM supercomputer Deep Blue beat world chess champion Garry Kasparov in 1997. It could also raise profound questions about whether a computer has the potential to be 'conscious' — and if humans should have the 'right' to switch it off."

musatov writes "There's talk on The Minor Planet Mailing List about a small asteroid approaching Earth with a 99.8% probability of colliding. The entrance to the Earth's atmosphere will take place October 7 at 0246 UTC (2:35 after this story goes live) over northern Sudan, releasing the energy of about a kiloton of TNT. The asteroid is assumed to be 3-4 meters in size; it is expected to burn up completely in the atmosphere, causing no harm. As a powerful bolide, it may put on quite a show in the sky. For those advanced enough in astronomy to observe, check the MPEC 2008-T50 and MPEC 2008-T64 circulars. NASA's JPL Small Body Database has a 3D orbit view. The story has been already picked up by CNN and NASA."
