Submission + - Concrete That Purifies The Air (gizmag.com)

fergus07 writes: Although much of the focus of pollution from automobiles centers on carbon emissions, there are other airborne nasties spewing from the tailpipes of fossil fuel-powered vehicles. These include nitrogen oxides (NOx). In the form of nitrogen dioxide it reacts with chemicals produced by sunlight to form nitric acid – a major constituent of acid rain – and also reacts with sunlight, leading to the formation of ozone and smog. Everyone is exposed to small amounts of nitrogen oxides in ambient air, but exposure to higher amounts, in areas of heavy traffic for example, can damage respiratory airways. Testing has shown that surfacing roads with air purifying concrete could make a big contribution to local air purity by reducing the concentration of nitrogen oxides by 25 to 45 percent.

Chewing gum is *the* single thing I truly despise in our free societies. It is ridiculously cheap, ubiquitous, popular - and more stable in the environment than granite. People chew that stuff all the time and spit it everywhere - all floors, streets, corners, sidewalks of all cities are riddled with that decades-old, positively eternal chewed chewing gum.

Just look at the streets on a busy intersection: thousands of flattened chewing gum remains, outlasting the tarmac they are embedded in by decades.

Sometimes when I look down on the city floor for some reason and notice the gum, I have a hard time regaining the faith in personal freedom, pushing back the urge to cry for Singaporean laws against that filth.

Honestly: what part of individual freedom demands that people can spit this stuff everywhere?

Solution? We build our roads out of chewing gum! Problem solved.

Browser Privacy Test 133

lazyforker writes "A NYTimes blog post reports the results of security researcher Kate McKinley's tests of various browsers' (FireFox, Chrome, IE, Safari) privacy protection mechanisms. Specifically she tested their cookie handling. She also examined their handling of Flash's cookies. In summary: Safari on Mac OS X (in the 'private browsing' mode) is not so private ('quirky'). Safari on XP is not private at all. Flash behaves awfully everywhere."

Google Chrome Tops Browser Speed Tests 371

Restaurant Owners Use Zapper To Cook the Books 454

Hugh Pickens passes along a NYTimes report on software programs called "zappers," which allow even technologically illiterate restaurant and store owners to siphon cash from computer cash registers to cheat tax officials. In the old days, restaurant owners who wanted to cheat kept two sets of books. But because cash registers make automated records, hiding the theft requires getting into the machine's memory and changing that record. "...the Canadian province of Quebec may be the world leader in prosecuting zapper cases. Since 1997, zappers have figured in more than 230 investigations, according to the tax collecting body Revenu Québec... In making 713 searches of merchants, Revenu Québec found 31 zapper programs that worked on 13 cash register systems. Only two known zapper cases have been prosecuted in the United States... The cash register security industry is focused on protecting patrons and owners from theft by employees, which may be one reason so few zappers are uncovered in the United States. No one hires security experts to protect the government from devious businesses... As hard as zapper software is to detect, it is easy to make, said Jeff Moss, organizer of the annual hacker convention Def Con. 'If it runs on a Windows system and you are a competent Windows administrator, you can do it,' he said."

ISS Dodges Space Junk For First Time In Five Years 141

Kligat writes "For the first time since 2003, the International Space Station has utilized the rockets on the European Space Agency's Automated Transfer Vehicle to dodge leftover remnants of a defunct satellite. The Russian Cosmos-2421 was launched in June 2006 to track Western Navy vessels and is believed by NASA to have exploded — 'likely due to a self-destruct command issued by Russian officials' according to the article — leaving 500 pieces of space debris. Ordinarily, the rockets on the ATV are used to take the ISS away from Earth's atmosphere and reduce drag. In this case, the 5-minute firing caused the ISS to move downward because it was already near the top of its acceptable range. Estimated probability of impact was 1 in 72, and an avoidance maneuver is called for if the probability is greater than 1 in 10,000. The space junk was predicted to pass the ISS within just a mile."

Smilin' Bob Not Smilin' Anymore 357

Consumerist reports an Associated Press release that Steve Warshak, 42, was found guilty of 93 counts of conspiracy, fraud and money laundering. His 75-year-old mother, who has cancer, was found guilty of conspiracy and other charges, and was sentenced to 2-years, but is free pending appeal. US District Judge Arthur Spiegel, in Cincinnati, OH, denied Mr. Warshak's request to remain free pending appeal, but gave him 30 days to wrap up his affairs and report to prison. Besides Enzyte, Washak's company, Berkeley Premium Nutraceuticals, who also distributes products to boost energy, manage weight, reduce memory loss and aid sleep, will be allowed to stay in business — but must forfeit $500 million. Among their most egregious offenses was a requirement of a Notarized statement from a doctor certifying that they had a small penis. Amazingly, remarkably few customers availed themselves of the refund offer. Unfortunately, it looks like the commercials will still be able to continue...

Comment Re:Defense against Linux boxes? (Score 1) 695

The Eee and its ilk have shown that people are willing to buy Windowsless boxes, which is an affront to Microsoft's business model. You have to wonder if Midori is a "plan B" to allow them to continue to get revenue from Linux users. Alan, Bob and Clarence may well be willing to pay $10 a month for "Windows access" on their Eees if it lets them use Office, and this way Microsoft have a guaranteed revenue stream whatever OS people actually buy with their machine. Especially if it's agressively marketed and bundled.

That may be all well for Alan, Bob and Clarence; but I'm sure ol' Steve has a thing or two to say about that.
