C# Memory Leak Torpedoed Princeton's DARPA Chances 560

nil0lab writes "In a case of 20/20 hindsight, Princeton DARPA Grand Challenge team member Bryan Cattle reflects on how their code failed to forget obstacles it had passed. It was written in Microsoft's C#, which isn't supposed to let you have memory leaks. 'We kept noticing that the computer would begin to bog down after extended periods of driving. This problem was pernicious because it only showed up after 40 minutes to an hour of driving around and collecting obstacles. The computer performance would just gradually slow down until the car just simply stopped responding, usually with the gas pedal down, and would just drive off into the bush until we pulled the plug. We looked through the code on paper, literally line by line, and just couldn't for the life of us imagine what the problem was.'"

Ubiquitous Multi-Gigabit Wireless Within Three Years 152

Anonymous Howard passed us a link to the Press Escape blog, and a post about the future of ultra-fast wireless connectivity. Georgia Tech researchers unveiled plans to use ultra-high frequency radio transmissions to achieve very high data transmission rates over short distances. In a few years, the article says, we'll have ubiquitous multi-gigabit wireless connectivity, with some significant advances already under their belts. "GEDC team have already achieved wireless data-transfer rates of 15 gigabits per second (Gbps) at a distance of 1 meter, 10 Gbps at 2 meters and 5 Gbps at 5 meters. 'The goal here is to maximize data throughput to make possible a host of new wireless applications for home and office connectivity,' said Prof. Joy Laskar, GEDC director and lead researcher on the project along with Stephane Pinel. Pinel is confident that Very high speed, p2p data connections could be available potentially in less than two years. The research could lead to devices such as external hard drives, laptop computers, MP-3 players, cell phones, commercial kiosks and others could transfer huge amounts of data in seconds while data centers could install racks of servers without the customary jumble of wires."

Drug Selectively Removes Rats' Memory 64

rednuhter writes "Nature online is reporting scientists have used drugs to selectively remove one memory while not affecting another. Musical tones were played to the rats and at the same time the subjects were given a mild electric shock. Half the study group were given the drug (not approved for use in humans) and then the experiment was repeated with a new tone. The following day the rats that had not been given the treatment were afraid of both tones while the treated half were only afraid of the second tone: the memory of fear of the first had been erased."

Anti-Missile Defenses For Commercial Jets 594

The AP reports that the first anti-missile defense system has been installed for testing on a commercial jet, a FedEx cargo carrier. The system is intended to detect the launch of a shoulder-fired missile at takeoff or landing, and disable the missile with a laser beam. Sen. Barbara Baxter (D-California) is one of the supporters of the system. She and other members of Congress are hoping to equip all US commercial passenger liners with this system in 20 years, at a cost of billions of dollars. Is this good common sense or the costly future of a society hobbled by fear of terrorism?

UK Woman Charged As Terrorist For Computer Files 470

Terror Alert Brown writes "Reuters is reporting that a UK woman has been charged as a terrorist because of computer files on her hard drive. According to the article, these files included 'the Al Qaeda Manual, The Terrorists Handbook, The Mujahideen Poisons Handbook, a manual for a Dragunov sniper rifle, and The Firearms and RPG Handbook.' She was picked up in connection with the plot stopped in August to detonate explosives in airplanes flying out of Heathrow airport. Now might be a good time to delete any copies of the Anarchist's Cookbook you once read for amusement and still have floating around on your hard drive."

How Much Does a Vista Upgrade Cost? 321

dptalia writes "Microsoft has rolled out its Vista upgrade program, where people can buy a qualifying PC with XP today and upgrade to Vista later for free. This article talks about what free really means. Some companies, such as Dell, charge $45 for converting to Vista Home from XP home. And then comes the question of actually trying to upgrade your computer... Is "free" really worth it?"

Network Neutrality Threatened In Norway 110

eirikso writes, "In June 2006 NextGenTel, one of the biggest broadband providers in Norway, decided to deliberately limit the bandwidth from the Norwegian Broadcasting Corporation. The CEO of NextGenTel, Morten Ågnes, told the Norwegian newspaper Aftenposten that they will give priority to the content providers who pay for better bandwidth. The Consumer Council of Norway takes this as a serious threat to network neutrality in Norway and wants to call a meeting with the biggest broadband providers in Norway to find a solution."

Administration Ignored Bin Laden Intel 800

gettin-bored noted a nice article running in very high priority on the Washington Post, right up there on page 17 of the print edition, where it's revealed that the CIA Director warned Rice about Bin Laden two months before 9/11. And strangely, the meeting was never mentioned during all the 9/11 commission reports making you really question what exactly they were actually hearing that was more important than the CIA director telling the National Security Advisor that Bin Laden was going to attack Americans.

Vista Hacking Challenge Answered 388

debiansid writes "Microsoft's most secure Operating System yet has been compromised at the Black Hat hacker conference. We all know that Andrew Cushman, Microsoft's director of security outreach invited the Black Hats over to touch and feel Vista in order to showcase the superiority of this OS. Joanna Rutkowska, from Coseinc, a Singapore-based security firm, obliged and showed how it is possible to bypass security measures in Vista that prevents unsigned code from running with the help of a little software she calls the 'Blue Pill.'" To be fair, the hack was possible only when the target is in administrator mode rather than a limited user account.

Congress vs Misleading Meta Tags 473

Krishna Dagli writes "The U.S. House of Representatives on Tuesday approved a bill that would make it a federal felony for Webmasters to use innocent words like "Barbie" or "Furby" but actually feature sexual content on their sites. Anyone who includes misleading "words" or "images" intended to confuse a minor into viewing a possibly harmful Web site could be imprisoned for up to 20 years and fined, the bill says." Terrible news for the Barbie/Furbie fetishists out there, to say nothing about being completely impossible to enforce globally.

UK Hackers Face Antisocial Behaviour Orders 444

ukhackster writes "The UK government has proposed that suspected cybercriminals could be banned from the Internet or have their PCs seized, even if they've not been convicted. These so-called Asbos have typically been used against teenage hoodlums or small-time crooks, but now they're gunning for organised criminals." From the article: "Asbos give the courts almost unlimited powers when imposing conditions on the person receiving the order. Under the Home Office proposals, the courts would have almost unlimited discretion to impose the order if they believe it probable that a suspect had 'acted in a way which facilitated or was likely to facilitate the commissioning of serious crime.' In a civil court, hearsay is admissible evidence, and the burden of proof is lighter than criminal courts."

FBI Planning New Net-Tapping Push 367

Section_Ei8ht writes to tell us CNet is reporting that the FBI is pushing for legislation to allow law enforcement officials free access to networking gear via built in backdoors for eavesdropping. From the article: "Jim Harper, a policy analyst at the free-market Cato Institute and member of a Homeland Security advisory board, said the proposal would 'have a negative impact on Internet users' privacy. People expect their information to be private unless the government meets certain legal standards,' Harper said. 'Right now the Department of Justice is pushing the wrong way on all this.'"

Next Step in ISP Control Panels? 111

rdelon writes "Finally there is some movement in the hosting provider control panel department. cPanel and Ensim have been around for years but some people have grown increasingly frustrated with them. WebFaction has developed a new type of control panel. It offers an Ajax web interface that decouples the application from the domain: the root of a website might be served by Ruby on Rails while the /blog URL might be served by WordPress; reciprocally, multiple websites might be served from a single Django application, which reduces the resource usage on the server. A screencast demo of the control panel is available on their blog."
