Comment Suggestions to EPA (Score 4, Interesting) 272
I submitted a comment to the EPA suggesting that the "Gallons / 100 Miles" number be more prominent relative to MPG. (Converting to metric is a lost cause, unfortunately.)
I also suggested that they add "Gallons SAVED per 100 miles" relative to an average car in its class. This statistic can be surprising: switching from a 33mpg Corolla to a 50mpg Prius saves one gallon per 100 miles, but switching from a 10mpg Hummer to a 14mpg Land Rover saves three gallons per 100 miles driven.

Browser-Based Jailbreak For iPhone 4 Released 154
WrongSizeGlass writes "Apple Insider is reporting on a browser-based 'jailbreak' for iPhone 4. Hackers on Sunday released the first 'jailbreak' for the iPhone 4, a browser-based exploit that allows users to run unauthorized code. Unlike previous jailbreaks, which required users to run software on their Mac or PC and tether their iPhone to their computer, the latest hack is done entirely within the Safari browser. Users simply visit the URL to begin the process, which modifies the iOS mobile operating system found on the iPhone, iPod touch and iPad. Some users have reported that the modification results in broken MMS and FaceTime functionality. This jailbreak does not work on iPads running iOS 3.2.1. "

Petaflops? DARPA Seeks Quintillion-Flop Computers 185
coondoggie writes "Not known for taking the demure route, researchers at DARPA this week announced a program aimed at building computers that exceed current peta-scale computers to achieve the mind-altering speed of one quintillion (1,000,000,000,000,000,000) calculations per second. Dubbed extreme scale computing, such machines are needed, DARPA says, to 'meet the relentlessly increasing demands for greater performance, higher energy efficiency, ease of programmability, system dependability, and security.'"
Amazon Seeks 1-Nod Ordering Patent 194
theodp writes "Amazon.com is famous for its patented 1-Click ordering system. But what about 1-Nod ordering? Amazon CEO Jeff Bezos is seeking a patent on a system that would let people make purchases with a nod, a smile, or even a raise of the eyebrow. Bezos' invention — 'Movement Recognition as Input Mechanism' — envisions a computing device that could interpret certain facial expressions and enhance or potentially replace conventional input devices such as keypads and touch screens."
Your Computer Or iPad Could Be Disrupting Sleep 351
Crash McBang sends in a CNN report on electronics and sleeplessness and asks, "So, what do Slashdotters do to get a good night's rest?" "More than ever, consumer electronics — particularly laptops, smartphones, and Apple's new iPad — are shining bright light into our eyes until just moments before we doze off. Now there's growing concern that these glowing gadgets may actually fool our brains into thinking it's daytime. Exposure can disturb sleep patterns and exacerbate insomnia, some sleep researchers said in interviews. ... Unlike paper books or e-book readers like the Amazon Kindle, which does not emit its own light, the iPad's screen shines light directly into the reader's eyes from a relatively close distance. That makes the iPad and laptops more likely to disrupt sleep patterns than, say, a television sitting across the bedroom or a lamp that illuminates a paper book, both of which shoot far less light straight into the eye, researchers said."

How Nintendo's Mario Got His Name
103
harrymcc writes "In 1981, tiny Nintendo of America was getting ready to release Donkey Kong. When the company's landlord, Mario Segale, demanded back rent, Nintendo staffers named the game's barrel-jumping protagonist after him. Almost thirty years later, neither Nintendo — which continues to crank out Mario games — nor Segale — now a wealthy, secretive Washington State real estate developer — like to talk about how one of video games' iconic characters got his name and Italian heritage. Technologizer's Benj Edwards has researched the story for years and provides the most detailed account to date."
Aral Sea May Recover; Dead Sea Needs a Lifeline 131
An anonymous reader writes "It's a tale of two seas. The drying up of the Aral Sea is considered one of the greatest environmental catastrophes in history, but the northern sector of the sea, at least, is showing signs of life. A dam completed in 2005 has increased the North Aral's span by 20 percent, and birds, fish, and people are all returning to the area. Meanwhile, the Dead Sea is still in the midst of precipitous decline, since too much water is being drawn out of the Jordan River for thirsty populations and crops. To keep the sea from shrinking more, scientists are pushing an ambitious scheme called the 'Red-Dead conduit,' which would channel huge amounts of water from the Red Sea to the Dead Sea. However, the environmental consequences of such a project may be troubling."
A Crowdsourcing Project To Make Predictions More Precise 69
databuff writes "Predictions are critical to modern life. Police predict where and when crimes are most likely to take place, banks predict which loan applicants are most likely to default, and hotels forecast seasonal demand to set room rates. A new project called Kaggle facilitates better predictions by providing a platform for forecasting competitions. The platform allows organizations to post their data and have it scrutinized by the world's best statisticians. It will offer a robust rating system, so it's easy to identify those with a proven track record. Organizations can choose either to follow the experts, or to follow the consensus of the crowd — which, according to New Yorker columnist James Surowiecki, is likely to be more accurate than the vast majority of individual predictions. The power of a pool of predictions was demonstrated by the Netflix Prize, a $1m data-prediction competition, which was won by a team of teams that combined 700 models. Kaggle's first competition is underway, and it is accessing the 'wisdom of crowds' to predict the winner of this May's Eurovision Song Contest." Understandably, participation requires registration.

Toyota Acceleration and Embedded System Bugs 499
An anonymous reader writes "David Cummings, a programmer who worked on the Mars Pathfinder project, has written an interesting editorial in the L.A. Times encouraging Toyota to drop claims of software infallibility in their recent acceleration problems. He argues that embedded systems developers must program more defensively, and that companies should stop relying on software for safety. Quoting: 'If Toyota has indeed tested its software as thoroughly as it says without finding any bugs, my response is simple: Keep trying. Find new ways to instrument the software, and come up with more creative tests. The odds are that there are still bugs in the code, which may or may not be related to unintended acceleration. Until these bugs are identified, how can you be certain they are not related to sudden acceleration?'"
