Comment Re:hydrogen cars (Score 1) 769

Since hydrogen has, at a theoretical best, a 1.0 eROI, it should never be considered an energy source.

Modern batteries (or even flywheels) are better at storing energy than stored hydrogen. The electric grids transmit energy more efficiently than hydrogen can be transported (except to exotic places where installing power lines is difficult. Like on a launching space shuttle.)

I think you can get that with a single spinning design. You can run in the same direction as the rotation (basically, faster rotation) and get a good workout. Or, you can leap in the opposite direction, and get around the rim pretty quick. Or you can just hang out in the "hub" and let the station turn around you.

Windows 7 Taskbar Not So Similar To OS X Dock After All 545

cremou brulee writes "Redmond's photocopiers have been unusually busy for the last couple of years, with the result that Windows 7 copies a lots of Mac OS X features. First and foremost among these is the Dock, which has been unceremoniously ripped off in Windows 7's new Taskbar. Or has it? Ars Technica has taken an in-depth look at the history and evolution of the Taskbar, and shows just how MS arrived at the Windows 7 'Superbar.' The differences between the Superbar and the Dock are analyzed in detail. The surprising conclusion? 'Ultimately, the new Taskbar is not Mac-like in any important way, and only the most facile of analyses would claim that it is.'"

Why Does the US Have a Civil Space Program? 308

BDew writes "The Presidents of the National Academy of Science and the National Academy of Engineering have commissioned a study on the Rationale and Goals of the US Civil Space Program. In short, the Academies are asking why the nation has a civil space program (including human, robotic, commercial, and personal spaceflight). The study is intended to provide a strategic framework for the nation's activities in space that can provide consistent guidance in an increasingly interconnected world. The members of the study committee are interested in the views (positive or negative) of the general public, particularly those people with a scientific and/or technological interest."

Recovering Moldy Electronics? 512

cookiej writes "We just completed having our basement gutted and our house decontaminated from mold. The finished basement is gone, my office floor has been removed as well as 24' of drywall around the base of the room. So, we had a full home theater downstairs along with a couple of computers in the electronics closet that were completely immersed (rainwater, not sewage). We moved them to a sheltered area outside and covered them with a plastic tarp. Since the electronics were off when the water hit them, 1) do I have a chance of recovering them? 2) If so, is there a way to clean them with some sort of liquid bath that would not damage the electronics? and 3) I don't want to bring moldy pieces back in the clean house. How could I decontaminate the electronics themselves, pre-bath? Not looking to save the speakers, just the amp, DirecTV box, video switch, etc. Thanks for any help, here, Slashdot."

"Stayin Alive" Helps You Stay Alive 31

In a small study conducted at the University of Illinois medical school, doctors and students maintained close to the ideal number of chest compressions doing CPR while listening to the Bee Gees hit, "Stayin' Alive." At 103 beats per minute, the old disco song has almost the perfect rhythm to help keep accurate time while doing chest compressions. The study showed the song helped people who already know how to do CPR, and the results were promising enough to warrant larger, more definitive studies with real patients or untrained people. I wonder what intrinsic power is contained in "How Can You Mend A Broken Heart?"

Steve Wozniak Predicts Death of the IPod 573

Slatterz writes "Apple co-founder Steve Wozniak, better known in the industry as 'Woz,' believes that the iPod is on its way out and has revealed his discomfort with some aspects of the iPhone. Wozniak said that the iPod has had a long time as the world's most popular media player, and that it will fall from grace due to oversupply. Wozniak also commented on the iPhone's proprietary nature and locked service provider, and compared it to Google's open Android platform. 'Consumers are not getting all they want when companies are very proprietary and lock their products down,' he said. 'I would like to write some more powerful apps than what you're allowed.'"

Plug-in Hybrids May Not Go Mainstream, Toyota Says 519

mattnyc99 writes "Honda's challenger to the Prius — the Insight hybrid that we discussed so lividly a month ago — got its official unveiling today at the Paris auto show, with insiders confirming it would be cheaper than the world's most popular 'green' car while still hitting the same fuel-efficiency range. But the hybrid-electric showdown comes in the midst of a sudden rethink by Toyota about plug-in hybrids. Apparently all the recent hype — over the production version of the Chevy Volt, plus Chrysler's new electric trio and even the cool new Pininfarina EV also unveiled today — has execs from the world's number one automaker, and alt-fuel experts, questioning how many people will really buy electric cars, whether people will really charge them at night to keep the grid clear, whether batteries will make them too expensive and more.

Submission + - SPAM: Software improves airdrops by 70%

coondoggie writes: "When it comes to airdropping tons of water on a huge forest fire or loads of food to flood survivors, dropping things from an airplane to a precise spot on the ground in the face of wind and nasty weather can be a black art. National Oceanic and Atmospheric Administration (NOAA) scientists have developed wind-forecast software that promise to improve aircraft airdrop target accuracy up to 70%. The US Air Force is already using they system for dropping Army cargo and paratroopers into Iraq and Afghanistan, but the package can be used for releasing almost any cargo from an airplane into a target area: water over a blazing wildfire, food to a famine-stricken population, or supplies, tanks, and Humvees into a war zone, NOAA said.

Submission + - Domains May Disappear After Search 1

Ponca City, We Love You writes: "A perfect domain name pops into your mind, a quick check at your registrar reveals that the domain is available, you put off the registration a few minutes and when you come back to register the domain, it's taken by someone else. How much time has elapsed between the search and the attempted registration — in one case, less than 90 seconds. Daily Domainer has an interesting story alleging that there may be a leak that allows domain tasters to intercept, analyze and register your domain ideas in minutes. "Every time you do a whois search with any service, you run a risk of losing your domain," says one industry insider. ICANN's Security and Stability Advisory Committee (SSAC ) has not been able to find hard evidence of Domain Name Front Running but they have issued an advisory (pdf) for people to come forward with hard evidence it is happening. Here is how domain name research theft crimes can occur and some tips to avoiding being a victim."

Submission + - Dissecting Apps Source Code for Vulnerabilities (net-security.org)

Chim3 writes: Application source code scanning for vulnerability detection is an interesting challenge and relatively complex problem as well. There are several security issues which are difficult to identify using blackbox testing and these issues can be identified by using whitebox source code testing methodlogy. Application layer security issues may be residing at logical layer and it is very important to have source code audit done to unearth these categories of bugs.
