Video Game Teaches Kenyan Youth HIV-Safety 75

QuackenDuck writes "The latest video-game headlines are all about virtual sex, violence, and taxes. Here's a story that turns the 'Think of the Children' battle-cry against games on its head. VOA News reports on how the video game medium is being used to educate Kenyan youths about risky behaviors that lead to HIV infection: 'Kenya has an HIV prevalence rate of about five percent, with young women among the most vulnerable to new infection. Now, the US government and a private entertainment company have teamed up to produce and distribute a video game that teaches Kenyan youth how to avoid contracting HIV, the virus that causes AIDS.' Many parts of the world are gritty, violent and dangerous, and this game designer is using gritty, violent and dangerous content to teach the children of Kenya."

Lawmakers Take Another Shot At Patent Reform 154

narramissic writes "Patent reform legislation was introduced yesterday (PDF), which, if it passes, would be the first major overhaul of US patent law in more than 50 years. (It should be noted that the new legislation is very similar to the Patent Reform Act of 2007, which died on the Senate floor last year.) The legislation would bring US patent law in line with global laws, and introduce 'reasonable royalty' provisions, which change the way damages are calculated and would reduce the likelihood of massive payouts for some patent holders. Representatives from Google, HP and Intel were quick to say that the changes would cut down on frivolous patent lawsuits. But the Innovation Alliance, a group representing patent-holders that oppose the legislation, said that it would 'devalue all patents, invite infringement — including from companies in China, India and other countries — and generate more litigation that will further strain the courts.'"

Analyzing Microsoft's Linux Lawsuit 297

jammag writes "Open source advocate Bruce Perens takes a close look at Microsoft's lawsuit against TomTom (discussed here last week), which involves an implementation of the Linux kernel, and calls it essentially a paper tiger. He notes: 'the technologies claimed in the 8 patents involved are so old and obvious that it's fair to say they have a high "Duh!" factor. There's an anti-trust angle to this suit that could blow up in Microsoft's face. And there's a high probability that some or all of the patents involved are invalid, due to recent court decisions.' Although the legal expense for TomTom to defend itself in court could be astronomical — meaning they may be forced to settle — in Perens' view Microsoft is aware its case is weak, yet hopes for a PR victory at limited cost." And reader nerdyH adds speculation from Open Innovation Network CEO Keith Bergelt that Redmond's action could be retaliation for TomTom's spurning a Microsoft acquisition bid in 2006.

New York Bill Aims To Restrict Games Containing Profanity 133

GamePolitics notes a new bill out of New York which seeks to prohibit "the sale to minors of certain rated video games containing a rating that reflects content of various degrees of profanity, racist stereotypes or derogatory language, and/or actions toward a specific group of persons." It goes on to say: "These games, containing adult images such as morbid violence, rape, alcohol and illegal drug use, as well as other malicious acts, are not appropriate for children under 18. This legislation will regulate the sale of such games." The full text of the bill is available. It also suggests that children who are exposed to in-game crimes are more likely to participate in real-life crime.

Mumbai Police To Enforce Wi-Fi Security 134

caffeinemessiah writes "In the wake of the recent terrorist attacks in Mumbai, India, the local police are going to be sniffing out unsecured wi-fi access points and ordering the owners to secure them. The article notes that 'terror mails were sent through unsecured Wi-Fi connections' before bomb blasts in other Indian cities. No word on if they'll be walking around using Kismet, or if people who use pathetically weak WEP encryption will be ordered to switch to more advanced protocols. Unfortunately, a gesture like this does not take into account the insidious scenario of walking into a cafe, buying a coffee and then (legally) using the cafe's wi-fi. Or the fact that terrorists might actually be able to pay to use a cybercafe, and know what VPNs are." On the other hand, the Mumbai police may still be keeping track of the mandatory keyloggers that went into the area's cybercafes in 2007.

DHS To Grab Biometric Data From Green Card Holders 248

An anonymous reader writes with this excerpt from Nextgov: "The Homeland Security Department has announced plans to expand its biometric data collection program to include foreign permanent residents and refugees. Almost all noncitizens will be required to provide digital fingerprints and a photograph upon entry into the United States as of Jan. 18. A notice (PDF) in Friday's Federal Register said expansion of the US Visitor and Immigrant Status Indicator Technology Program (US VISIT) will include 'nearly all aliens,' except Canadian citizens on brief visits. Those categories include permanent residents with green cards, individuals seeking to enter on immigrant visas, and potential refugees. The US VISIT program was developed after the Sept.11, 2001 terrorist attacks to collect fingerprints from foreign visitors and run them against the FBI's terrorist watch list and other criminal databases. Another phase of the project, to develop an exit system to track foreign nationals leaving the country, has run into repeated setbacks." Reader MirrororriM points out other DHS news that they're thinking about monitoring blogs for information on terrorists.

Vista To XP Upgrade Triples In Price, Now $150 907

ozmanjusri writes "Dell has tripled the charge to upgrade Vista PCs to XP. Under current licensing 'downgrade' agreements, system builders can install XP Pro instead of Vista Business or Vista Ultimate; however, Dell has opted for a surcharge of $150 over the price of Vista for the older but more popular XP Professional operating system. Rob Enderle says the downgrade fees could potentially be disastrous for Microsoft: 'The fix for this should be to focus like lasers on demand generation for Vista but instead Microsoft is focusing aggressively on financial penalties," says Enderle. 'Forcing customers to go someplace they don't want to go by raising prices is a Christmas present for Apple and those that are positioning Linux on the desktop.'"

Guitarist Hopes To Play Again With The Help of Bionic Hand 72

Dorian Cox, the 27-year-old guitarist of the indie band The Long Blondes, thought his guitar playing days were over after he suffered a stroke. He now has a glimmer of hope thanks to some neurological physiotherapy which includes a cutting-edge piece of medical technology. The SaeboFlex helps patients by supporting their wrists and helping them grasp and release objects. "It's a fantastic service, it's helping tremendously and I think it can work wonders for me and others — it's almost like a gym for my hand. I know things might never be the same again and nobody can give me a definite answer about whether I'll play guitar again but I'm getting back on track with their help," Mr. Cox said. This thing looks really cool, and I'm sure many people will benefit from it, though I can't help but wonder if they make a model that lets you shoot your fist at an enemy.

U-Turn On UK ID Cards 143

An anonymous reader writes "The UK appears to be watering down its national ID card system, with the revelation by the government that it will now only check the cards against a central biometric database in a minority of cases. Critics are saying it not only renders the whole scheme pointless, but will pose a security risk by making it far easier to use copied or cloned cards. 'But an Identity and Passport Service spokesman denied the system would be vulnerable to fraud: 'The majority of instances where people use their identity cards will be day-to-day situations where the cards offer a convenient method of proving identity such as a young person proving their age to buy alcohol,' he said.'"

Halloween Pumpkin Carving With CNC Robotics 73

An anonymous reader writes "A guy at Lumenlab has created a way to carve his face on a pumpkin using his DIY CNC gantry robot. I think this demonstration says a lot about the future ubiquity of the technology. I'm really looking forward to the day that I have one of these machines in my garage."

Normal sporting parachutes are required to open in less than 300ft. Mains usually open in the 300-1000ft range. (Anything less quickly becomes painful, anything more is waste of altitude.) Rossy's canopies are probably tandems due to the extra wing weight, so they'll open in about twice the the distance.

The Duke Is Finally Back, For Real 309

After the first announcement on 1997-04-27 and over eleven years of fresh start after fresh start, Duke Nukem Forever finally comes to your system. At least if your system is an Xbox 360. Jon Siegler, the webmaster of 3D Realms, confirms this on their site: "As has been reported around the net today, we can confirm that the game has indeed passed final certification with Microsoft on Friday the 15th of August (on our first try, no less). That means the game is done — it is now in the hands of Microsoft." Update: 08/19 10:47 GMT by T : Several readers have written with a correction: this announcement is actually about Duke Nukem 3D, rather than Duke Nukem Forever.

Comment Re:Iron Man's Suit Defies Physics -- Mostly (Score 2, Interesting) 279

Hydrogen peroxide powered rocket packs fly for around 30 seconds, because they have a specific impulse of around 125, meaning that one pound of propellant can make 125 pound-seconds of thrust, meaning that it takes about two pounds of propellant for every second you are in the air. Mass ratios are low for anything strapped to a human, so the exponential nature of the rocket equation can be safely ignored.

A pretty hot (both literally and figuratively) bipropellant rocket could manage about twice the specific impulse, and you could carry somewhat heavier tanks, but two minutes of flight on a rocket pack is probably about the upper limit with conventional propellants.

However, an actual jet pack that used atmospheric oxygen could have an Isp ten times higher, allowing theoretical flights of fifteen minutes or so. Here, it really is a matter of technical development, since jet engines have thrust to weight ratios too low to make it practical. There is movement on this technical front, but it will still take a while.

Study Finds Film Enjoyment Is Contagious 129

Hugh Pickens writes "A report from Science Daily says that scientists have proven that the presence of other people may enhance our movie-watching experiences by influencing and gradually synchronizing viewer emotional responses. This mutual mimicry also affects each participant's evaluation of the overall experience — the more in sync we are with the people around us, the more we like the movie. In a series of experiments, researchers found that people watching a film together appeared to evaluate the film within the same broad mood and another study found that synchrony of evaluations can be traced to glances at the other person during the film and adoption of the observed expressions. 'By mimicking expressions, people catch each other's moods leading to a shared emotional experience. That feels good to people and they attribute that good feeling to the quality of the movie,' said one researcher."
