Here it is, the latest issue of the Developer Shed newsletter. With everyone worried about a greener environment these days, we thought you'd be very interested in the item we're highlighting this week from eWeek. It's a 21-minute podcast in which Drew Clark, co-founder of IBM's Venture Capital Group, explains how the carbon trading market works and the IBM-developed SOA technology behind it. If you've ever wondered how carbon trading credits work, you're in for an education. Of course we have our usual excellent selection of articles for you this week. On Dev Shed, we continued our series of articles on destructors, Yahoo Web Services, and Python. If you're more into Microsoft-related technologies, check out ASP Free; we finally finish our series on building an online shopping website, and show you how to give WSH a nice-looking user interface. We also continue our series on C. If you're a web designer, you'll want to head over to Dev Articles. We published articles on HTML, JavaScript, and graphic design this week. If you're a hardware enthusiast, you'll appreciate this week's articles on Dev Hardware. We reviewed a super zoom digital camera and two GPS units; we also took a look at perpendicular recording, a new technology that is supposed to speed up hard drives. Over on SEO Chat, we know all of you SEO professionals were buzzing about the news of Microsoft's offer to buy Yahoo, and we were right on top of that for you. We also ran an article on the most important quality you need to build into your landing pages, and which SEO mistakes can really cost you. Finally, we've highlighted a nice group of tutorials for you on Tutorialized. You'll learn how to animate cars and stick figures, create a background of glowing radial beams, and more! As always, thanks for reading. Until next week,Developer Shed Staff |

It leaves the rest of us asking two questions: what are the deal’s implications? And will it actually go through? Read the full article. |
File Sharing, Break It Down! by Michael Lowry, 2008-02-06 -- For all the Internet has done to benefit both business and the individual, there are some corporations that would have you think the Internet has been the biggest burden to capitalism since Karl Marx. They think of it as a world that caters to thieves and ne'erdowells, while they, being oh so chaste, are forced to survive without rules or protection of any kind. It's time we see how dangerous this “Internet” really is when it comes to intellectual property rights. Read the full article. Registrar Responsibility by Michael Lowry, 2008-01-30 -- Imagine that you own a company that provides a service to customers who also run a business of some sort.

Domain registrars and web hosting companies have long been teetering on the edge of this cliff, mainly because “cybersquatting” techniques continue to grow. Read the full article.

Centralized Data Backup Won`t Cripple Your WAN IT organizations have been conflicted between two backup approaches: local and centralized. While centralized backup requires less hardware, reduces administration time, and solves the security problem associated with loose tape media, it can introduce greater bandwidth consumption and longer backup/restore windows. Because of these issues, centralized backup has been a leap some managers have not been willing to make. Request Your Free White Paper!

Weird and Cool Tracking Big Oil Politicians Have you ever wondered how much money political candidates accept from various lobbying groups? Now you can find out, at least for contributions from oil companies and oil-related PACs. OilChange International is hosting an online interactive graphic that shows you how much oil money various presidential candidates have accepted during their campaign. In addition to the presidential races, you can also check the candidates for Congress. Though it defaults to showing the 2008 view, you can also check out the contributions for 2000 and 2004. So you can see that George W. Bush accepted nearly $2 million from Big Oil in 2000, and more than $2.6 million in 2004. You can adjust the views to focus on politicians or companies, and click on various points to show the details. When you play around with the graphic, you quickly discover that both Democrats and Republicans accept money from Big Oil, and not all politicians who accept Big Oil money are from Texas (though that does seem to be a strong trend). You also discover that Big Oil contributions don't always decide races; Giuliani accepted more than half a million dollars from Big Oil, but still had to pull out of the race. Robots Get the Worst Jobs Hardly anybody seems to use the full service option at gas stations anymore because of the expense. Dutch inventors just might have figured out a way to make it cost less, with the assistance of a new robot that fills automobile gas tanks. The robot - really a robotic arm - costs $111,100 and works by matching the car to its database of fuel cap designs and fuel types. The arm is fitted with multiple sensors that guide it while it opens the car's flap, unscrews the cap, picks up the fuel nozzle and puts it in the tank opening. The inventor hopes to place his robot in a select group of Dutch gas stations by the end of this year. Developer Nico van Staveren said he was inspired to invent the robot when he saw a robotic arm milking a cow. He noted that his invention would mean that "Drivers needn't get dirty hands or smell of petrol again." The robotic arm works for any car in the database; it does not work for cars whose tanks need to be opened with a key. Now That's a Power-Saving Chip What if we had chips that were so efficient they could enable gadgets to run on body heat and movement alone? MIT researchers have developed a chip that fits that description. It uses 70 percent less voltage than current chip technologies, opening up a world of possibilities. Anantha Chandrakasan, a professor of electrical engineering at MIT, notes that the technology "will extend the battery lifetime of portable devices in areas like medical electronics." Such low-power chips also have military uses, in body and environmental sensors for example. Nokia and Intel hope to use low-voltage chips in cell phones and computers. Low-voltage chips are tricky to design because voltage changes are what tell transistors to turn on and off - letting information be stored as 1s and 0s. At low voltages, if there is any variation in your transistors, it can cause errors. The research team at MIT came up with a design that could handle transistor variation.
