Why LEDs Don't Beat CFLs Even Though They Should 685

TaeKwonDood writes "LEDs don't beat CFLs in the home yet, but it's not simply because PG&E is getting rich making people feel like they are helping the environment buying CFLs made in China that are shipped to the US using a lot more fossil fuels than they save. It's a problem of indication versus illumination. However, some new discoveries are going to change all that."

An economic disincentive for our kids to do homework. That is not what we as a nation or any society on this planet need. Somehow I think we are missing part of the proposal. Of course I haven't looked into it beyond one of the links. I just don't see how anyone is going to find this arrangement appealing! There will be a massive outcry if they try to force this on people and it will die an even more pathetic death than Vista. Well, that is my first reaction and I don't think I care enough to look into any further... Heh.

An In-Depth Look At Game Piracy 504

TweakGuides is running a detailed examination of PC game piracy. The author begins with a look at the legal, moral, and monetary issues behind copyright infringement, and goes on to measure the scale of game piracy and how it affects developers and publishers. He also discusses some of the intended solutions to piracy. He provides examples of copy protection and DRM schemes that have perhaps done more harm than good, as well as less intrusive measures which are enjoying more success. The author criticizes the "culture of piracy" that has developed, saying. "Fast forward to the 21st century, and piracy has apparently somehow become a political struggle, a fight against greedy corporations and evil copy protection, and in some cases, I've even seen some people refer to the rise of piracy as a 'revolution.' What an absolute farce. ... Piracy is the result of human nature: when faced with the option of getting something for free or paying for it, and in the absence of any significant risks, you don't need complex economic studies to show you that most people will opt for the free route."

Change.gov Uses Google Moderator System 436

GMonkeyLouie writes "The website for President-elect Obama's transition team, Change.gov, has unveiled a section called Open for Questions, which lets users submit questions and vote them up or down, in an effort to let the collaborative mind produce the questions that are the most important to the American populace (or at least the web-savvy portion). The page is powered by Google Moderator. It was unveiled yesterday, and CNet reports that when they went to post last night, '159,890 had voted on 1,986 questions from 3,255 people.'"

Intel On Track For 32 nm Manufacturing 139

yaksha writes "Intel said on Wednesday that it has completed the development phase of its next manufacturing process that will shrink chip circuits to 32 nanometers. The milestone means that Intel will be able to push faster, more efficient chips starting in the fourth quarter. In a statement, Intel said it will provide more technical details at the International Electron Devices Meeting next week in San Francisco. Bottom line: Shrinking to a 32 nanometer is one more step in its 'tick tock' strategy, which aims to create a new architecture with new manufacturing process every 12 months. Intel is obviously betting that its rapid-fire advancements will produce performance gains so jaw dropping that customers can't resist."

The Science of the Lightsaber Screenshot-sm 197

Smartcowboy writes "Chances are that you have seen a lightsaber at one time or another, whether on the evening news or down at the local cantina. Therefore you know that a lightsaber is an amazing and versatile device that is able to cut through nearly anything in a matter of milliseconds. Have you ever wondered how these remarkable weapons work? Where does the energy come from, and how are they able to contain that energy in a rod-like column of glowing power? In this article, you will have a chance to look inside a lightsaber and discover the source of its incredible characteristics." I was sure the blade was made from the focused hate and disappointment of the last three movies.

PC Makers Try To Pinch Seconds From Their Boot Times 399

Some computers are never turned off, or at least rarely see any state less active than "standby," but others (for power savings or other reasons) need rebooting — daily, or even more often. The New York Times is running a short article which says that it's not just a few makers like Asus who are trying to take away some of the pain of waiting for computers, especially laptops, to boot up. While it's always been a minor annoyance to wait while a computer slowly grinds itself to readiness, "the agitation seems more intense than in the pre-Internet days," and manufacturers are actively trying to cut that wait down to a more bearable length. How bearable? A "very good system is one that boots in under 15 seconds," according to a Microsoft blog cited, and an HP source names an 18-month goal of 20-30 seconds.

New State of Matter Could Extend Moore's Law 329

rennerik writes "Scientists at McGill University in Montreal say they've discovered a new state of matter that could help extend Moore's Law and allow for the fabrication of more tightly packed transistors, or a new kind of transistor altogether. The researchers call the new state of matter 'a quasi-three-dimensional electron crystal.' It was discovered using a device cooled to a temperature about 100 times colder than intergalactic space, following the application of the most powerful continuous magnetic field on Earth."

Economic Crisis Will Eliminate Open Source 753

An anonymous reader writes "The economic crisis will ultimately eliminate open source projects and the 'Web 2.0 free economy,' says Andrew Keen, author of The Cult of the Amateur. Along with the economic downturn and record job loss, he says, we will see the elimination of projects including Wikipedia, CNN's iReport, and much of the blogosphere. Instead of users offering their services 'for free,' he says, we're about to see a 'sharp cultural shift in our attitude toward the economic value of our labor' and a rise of online media businesses that reward their contributors with cash. Companies that will survive, he says, include Hulu, iTunes, and Mahalo. 'The hungry and cold unemployed masses aren't going to continue giving away their intellectual labor on the Internet in the speculative hope that they might get some "back end" revenue,' says Keen."

Geoengineering To Cool the Earth Becoming Thinkable 419

johkir writes "As early as 1965, when Al Gore was a freshman in college, a panel of distinguished environmental scientists warned President Lyndon B. Johnson that CO2 emissions from fossil fuels might cause 'marked changes in climate' that 'could be deleterious.' Yet the scientists did not so much as mention the possibility of reducing emissions. Instead they considered one idea: 'spreading very small reflective particles' over about five million square miles of ocean, so as to bounce about 1 percent more sunlight back to space — 'a wacky geoengineering solution.' In the decades since, geoengineering ideas never died, but they did get pushed to the fringe — they were widely perceived by scientists and environmentalists alike as silly and even immoral attempts to avoid addressing the root of the problem of global warming. Three recent developments have brought them back into the mainstream." We've discussed some pretty strange ideas in the geoengineering line over the last few years.

And Apple is just the company to deliver it. The whole system for watching TV, whether it is movies or other regular TV, is broken. It is a pain in the ass. There is too much chaos. Apple has done a very good job, judging by market success, at creating an orderly, pleasing user experience for both music players and smart phones. You can count on it that they are working on something for video delivery, and video on the iPod is not the end of it. As far as it being announced soon, that too is plausible. They have certainly had enough time to work on it. Technology has advanced since the Apple TV, which didn't interest me but, I am certainly curious to see what they come up with next for that space.

Geneticist Claims Human Evolution Is Over 857

GogglesPisano writes "UK geneticist Steve Jones gave a presentation entitled Human Evolution Is Over. He asserts that human beings have stopped evolving because modern social customs have lowered the age at which human males have offspring, which results in fewer of the mutations necessary to drive evolutionary change. Apparently the fate of our species now depends upon older guys hooking up with younger woman. I, for one, welcome this development."

Nagios 3 Enterprise Network Monitoring Screenshot-sm 147

jgoguen writes "Nagios, originally known as Netsaint, has been a long-time favourite for network and device monitoring due to its flexibility, ease of use, and efficiency. Nagios provided, and still provides today, a low-cost, versatile alternative to commercial network monitoring applications. Nagios 3 takes a huge step forward compared to Nagios 2, providing improved flexibility, ease of use and extensibility, all while also making significant performance enhancements. Due to its extensibility and ease of use, no device or situation has yet been found that cannot be monitored using Nagios and a pre-made or custom script, plug-in or enhancement." Read on for the rest of jgoguen's review.

FTC Bans Prerecorded Telemarketing Drivel 381

coondoggie writes "In the ongoing battle to let us eat dinner in peace without being interrupted by amazingly annoying telemarketer blather, and in this case the even more infuriating recorded telemarketing drivel, the Federal Trade Commission today basically outlawed recorded telemarketing calls. Specifically, the FTC changed its venerable Telemarketing Sales Rule (TSR) to prohibit, as of Sept. 2009, telemarketing calls that deliver prerecorded messages, unless a consumer has agreed to accept such calls from a given caller/seller. Between now and 2009, telemarketers must provide an obvious, easy and quick way for consumers to opt-out of any call, the FTC said. Such an opt-out mechanism needs to be in place by December 1, 2008."

Duke Nukem Forever Preview On Jace Hall Show 341

An anonymous reader writes "The Jace Hall Show launched today on Sony's Crackle with a real gameplay preview of Duke Nukem Forever. Jace Hall is a former video game producer and Warner Bros exec and apparently this is his foray into online celebrity. DNF is 12 years in development ... it might be real after all." And if you have had enough self-indulgent gaming-news patter, another reader says "If you want to simply skip right ahead, it's about 4:20 in."
