theodp writes "Newsweek reports that high-schoolers are being denied the joy of ordering unhealthy lunches thanks to their schools' adoption of services like MealpayPlus. New web-based services allow moms to prepay for cafeteria food, specify what their kid can and can't buy, and go online to track his purchases." From the article: "If the child tries to buy a prohibited item, an alert flashes on the cashier's computer. Of course, the system isn't foolproof. According to a KRC Research survey, 73 percent of 8- to 12-year-olds are throwing out part of their lunches at least once a week; 36 percent are trading them." All I ever got was PB&J.

Roland Piquepaille writes "A substance found in crab shells called chitosan has very useful properties. For example, it has been used in bandages to stop bleeding. But now, researchers at the University of Maryland have used the chitosan from blue crabs living in Chesapeake Bay as a component of a nanoscale sensor system which could save many lives in the future. These blue crab nanosensors will be used to improve security in airports, hospitals and other public locations by detecting tiny amounts of explosives or chemicals in air and water. Read on for additional references and pictures of these blue crab nanosensors."

feminazi writes "Flash memory is being integrated with the hard disk by Seagate and Samsung and onto the motherboard by Intel. Potential benefits: faster read/write performance; fewer crashes; improved battery life; faster boot time; lower heat generation; decreased energy-consumption. Vista's ReadyDrive will use the hybrid system first for laptops and probably for desktops down the road. The heat and power issues may also make it attractive in server environments."

douder writes "Windows Vista will have a new 'previous versions' feature when it ships next year. According to Ars Technica, the feature is built off of the volume shadow copy technology from Windows XP and Windows Server 2003. Now turned on by default, the service stores the modified versions of a user's documents, even after they are deleted. They also report that you can browse folders from within Explorer to see snapshots of what they contained over time. It can be disabled, but this seems like a privacy concern." From the article: "Some users will find the feature objectionable because it could give the bossman a new way to check up on employees, or perhaps it could be exploited in some nefarious way by some nefarious person. Previous versions of Windows were still susceptible to undelete utilities, of course, but this new functionality makes browsing quite, quite simple. On the other hand, it should be noted that 'Previous Versions' does not store its data in the files themselves. That is, unlike Microsoft Office's 'track changes,' files protected with 'Previous Versions' will not carry their documentary history with them."

zer0skill writes to mention a CNN summary of a Time cover story. The Truth about Stem Cells deals with an increasingly politicized area of scientific inquiry, and likens the fight to those over global warming and evolution. From the article: "Five years after Bush announced that federal money could go to researchers only working on embryonic stem cell lines that scientists had already developed, Democrats hope to leverage the issue as evidence that they represent the reality-based community, running against the theocrats. States from Connecticut to California have tried to step in with enough funding to keep the labs going and slow the exodus of U.S. talent to countries like Singapore, Britain and Taiwan."

ennuiner writes "Over at Newsweek Steven Levy has a column commemorating IBM's introduction of the first hard drive 50 years ago. The drive was the size of two refrigerators, weighed a ton, and had a vast 5MB capacity. They also discuss the future of data storage." From the article: "Experts agree that the amazing gains in storage density at low cost will continue for at least the next couple of decades, allowing cheap peta-bytes (millions of gigabytes) of storage to corporations and terabytes (thousands of gigs) to the home. Meanwhile, drives with mere hundreds of gigabytes will be small enough to wear as jewelry."

An anonymous reader writes "For the first time, you can smack your computer and get a meaningful response! An article at IBM Devworks show you how to rap on the laptop case with your knuckles and have commands run on those knocks. Enterprising hackers have developed modules for the Linux kernel to take advantage of laptop integrated accelerometer sensors; with them the possibilities are endless."

Ground Glass writes "Next Generation is reporting that E3 as we know it is finished. The games industry has lost its most glamorous show." Update: 07/30 21:18 GMT by Z : A reader wrote in with a link to an Ars Technica story saying that the event is to be downsized, not cancelled. From that article: "At the end of the day, the reason is very simple: ten years ago, you needed a big trade show to generate buzz and hype. It used to be that COMDEX was a special event because so much new stuff was unveiled, and this was the only way to see it. Now, however, information comes down the pipe faster than ever, and companies are wondering if there's really any benefit to spending the big money on displays only to share the floor with other competitors looking to out-wow attendees." I guess we'll see in a day or two what the future of E3 looks like.

An anonymous reader writes "Whitedust is running an interesting article on honeypots and their uses. From the article: 'Most papers deal with the potential gains a honeypot can give you, and the proper way to monitor a honeypot. Not very many of them deal with the honeypots themselves... Honeypots can be used to ensnare and beguile potential hackers; entice them to give you more research information, and actively defend your production network."" From the article: "Once an attacker has taken all the trouble to set up shop on your honeypot, he'll probably want to see what else there is to play with. If your honeypot is like most traditional honeypots, there's not much for an attacker to do once he gets in. What you really want if for the attacker to transfer down all the other toys in his arsenal so you can have a copy as well. Giving an attacker additional targets with various operating systems and services can help him decide to give you his toys. The targets can be real, but you'll get almost as much mileage if they're simulated. A good place to start is to put a phantom private network up hung off the back of the honeypot."

WilliamSChips writes "The United States military has announced that they are shutting down the facility at Cheyenne Mountain, home to the high-tech NORAD which tracks every object in the sky. NORAD's operations will be moved to the nearby Peterson Air Force base. The mountain facility is being placed on standby in case they need it again." From the article: "The Cheyenne Mountain center, at the eastern foot of the Rockies near the base of Pikes Peak, was constructed underground in the mid-1960s. Fearing nuclear attacks at the time, the United States built sites such as the Cheyenne Mountain complex. The Navy prepared a floating White House aboard the communications cruiser USS Northampton, in case the president needed to be evacuated from U.S. soil. Another protective bunker was created near White Sulphur Springs, W.Va., for members of Congress."

Vexorian writes "Two NASA websites were hacked today by a group of Chilean activist hackers. The reason was to protest against the war on Lebanon. The mirror of the defaced site contains an image of an injured child and claims that the sites were running MacOSX."

PunkOfLinux writes "My parents are running a pirated copy of windows that my mom received from a teacher at school. My parents want to go legit, and buy a copy of Windows, but they are afraid of deleting everything and having to reinstall all their programs. Seeing as I know you guys will have an answer, I'm going to ask you: What would you do in this situation?"

slashthedot writes "Japan has built the fastest supercomputer in the world. While the BlueGene/L contains 130,000 processors, Japan has managed to create the first Petaflop supercomputer, called MDGrape-3, with just 4808 chips, and it cost just $9 million to develop."

An anonymous reader writes "C|Net is reporting that JavaScript malware is opening the door for hackers to attack internal networks. During the Black Hat Briefings conference Jeremiah Grossman (CTO, WhiteHat Security) '...will be showing off how to get the internal IP address, how to scan internal networks, how to fingerprint and how to enter DSL routers ... As we're attacking the intranet using the browser, we're taking complete control over the browser.' According the the article, the presence of cross-site scripting vulnerabilities (XSS) dramatically increase the possible damage that can be caused. The issue also not which-browser-is-more-secure, as all major browsers are equally at risk. Grossman says 'The users really are at the mercy of the Web sites they visit. Users could turn off JavaScript, which really isn't a solution because so many Web sites rely on it.'"

Servo writes "Last month a man was arrested in New Hampshire after presenting evidence of a police officer being verbally abusive that he had captured on his home security camera system. Now just recently in Philadelphia a 21 year old student was arrested on his property after he took a photo of the police who were in the process of arresting a drug dealer down the street." From the article: "Cruz said that when he heard a commotion, he walked out of his back door with his cell phone to see what was happening. He said that when he saw the street lined with police cars, he decided to take a picture of the scene. 'I opened (the phone) and took a shot,' Cruz said. Moments later, Cruz said he got the shock of his life when an officer came to his back yard gate."
