Hugh Pickens writes "NPR reports that owners of ships that ply the dangerous waters near Somalia are looking at options to repel pirates including slippery foam, lasers, electric fences, water cannons and high-intensity sound — almost anything except guns. One defense is the Force 80 squirt gun with a 3-inch nozzle that can send 1,400 gallons a minute 100 yards in any direction. 'It is a tremendous force of water that will knock over anything in its path and will also flood a pirate's ship very quickly,' says Roger Barrett James of the the Swedish company Unifire. Next is the Mobility Denial System, a slippery nontoxic foam that can be sprayed on just about any surface making it impossible to walk or climb even with the aid of a harness. The idea would be to spray the pirate's vessel as it approached, or to coat ropes, ladders, steps and the hull of the ship that's under attack. The Long Range Acoustic Device, or LRAD, a high-powered directional loudspeaker allows a ship to hail an approaching vessel more than a mile away. 'Knowing that they've lost the element of surprise is half the battle,' says Robert Putnam of American Technology Corp. The LRAD has another feature — a piercing "deterrent tone" that sounds a bit like a smoke detector alarm with enough intensity to cause extreme pain and even permanent hearing loss for anyone directly in the beam that comes from the device. But Capt. John Konrad, who blogs for the Web site Gcaptain.com, says no anti-pirate device is perfect. 'The best case scenario is that you find these vessels early enough that you can get a Navy ship detached to your location and let them handle the situation.'"

walrabbit writes "Wang et al (2009) (from Albert-László Barabási's lab) modeled the spread of mobile phone viruses based on anonymised call and text logs of 6.2 million customers spread over 10,000 towers. Their simulations shows that the spread is dependent on the market share of a particular handset, human mobility and mode of spread: bluetooth or MMS or hybrid. 'We find that while Bluetooth viruses can reach all susceptible handsets with time, they spread slowly due to human mobility, offering ample opportunities to deploy antiviral software. In contrast, viruses utilizing multimedia messaging services could infect all users in hours, but currently a phase transition on the underlying call graph limits them to only a small fraction of the susceptible users. These results explain the lack of a major mobile virus breakout so far and predict that once a mobile operating system's market share reaches the phase transition point, viruses will pose a serious threat to mobile communications.'

IGN reports that Prince of Persia will be getting downloadable content on February 26th for the PS3 and Xbox 360 versions of the game. It will be an epilogue to the original game, and it will add about three hours of gameplay. "Expect everything to be at a higher pace and to keep you on the edge of your seat. Figuring out how to succeed passing this long acrobatic sequence mined with traps or how to defeat this boss before he regenerates his energy will definitely be more intense. What hardcore Prince of Persia gamers want is a challenge and some of them found the game too easy. We understand this. Seeing such feedback, our vision and intentions with the DLC coincided with their comments quite well. We wanted to build a challenge and experience even greater with all the tools at our disposal, and let me say that there are a lot: Elika's power, traps, combat system, etc."

Zonk pointed out an interesting video presentation by Shamus Young on the importance of the new Prince of Persia, calling it the most innovative game of 2008. Young brings up the fact that many of today's games punish failure by wasting the player's time; being sent back to a check point, the beginning of a level, or sometimes even further. This cuts into the amount of time players have to enjoy the meat of the game — the current challenge they have to overcome. Unfortunately, as Young notes, modern controllers are designed for players who have been gaming since they were kids, and have evolved to be more complicated to operate than an automobile. The combination of these factors therefore limits or prevents the interest of new players; a problem Prince of Persia has addressed well through intuitive controls and the lack of punitive time sinks.

A new study of 86 galaxy clusters in the early universe has provided independent confirmation of the existence of dark energy. In its absence, gravity's pull should have caused the number of clusters to increase by a factor of 50 over the last 5.5 billion years. What is observed is a factor of 10 increase. "Together with earlier observations... the new data strengthen the suspicion — but do not prove — that dark energy is a weird antigravity called the cosmological constant that was hypothesized and then abandoned by Albert Einstein as a 'blunder' almost a century ago. If that is true, the universe is fated to empty itself out eventually, and all but the Milky Way's closest neighbors will eventually be out of sight. ... Adam Riess of Johns Hopkins and the Space Telescope Science Institute, said: 'If this was a fox hunt and dark energy was the fox, I think they have closed off another escape route. But there is still a lot of terrain left for the fox, and we've seen little more than a glimmer of fur.'"

Ars Technica reports that the upcoming PC version of Ubisoft's Prince of Persia will not feature any sort of copy protection. (Not including Steam downloads, of course.) After the backlash in recent months over the DRM in games like Spore and GTA IV, Ubisoft is giving gamers the chance to demonstrate that DRM actually increases piracy. One of Ubisoft's community reps had this to say about their decision: "You`re right when you say that when people want to pirate the game they will but DRM is there to make it as difficult as possible for pirates to make copies of our games. A lot of people complain that DRM is what forces people to pirate games but as PoP PC has no DRM we`ll see how truthful people actually are. Not very, I imagine. Console piracy is something else entirely and I`m sure we`ll see more steps in future to try to combat that."

NewYorkCountryLawyer writes "The RIAA's 'Prince of Darkness,' Washington DC lawyer Matthew Jan Oppenheim of The Oppenheim Group, who controls and supervises all of the RIAA litigations against ordinary folks, has requested permission to intervene in the 'probable cause' hearing scheduled next week in Raleigh, North Carolina, against MediaSentry. The hearing was convened by North Carolina's Private Protective Services Board, after complaints were filed by a law firm representing a number of North Carolina State University students who had been targeted by the RIAA based on the unlicensed 'investigation' conducted by SafeNet (the new name for MediaSentry). I guess the RIAA is worried. They should be."

Joystiq reports that work on Ubisoft's re-imagined Prince of Persia is complete, and the game has been sent off for certification leading up to its scheduled December 2nd launch. They were able to get some hands-on time with the game, and they have nothing but praise for the controls and the combat system. Quoting: "The game walked us through several fights' worth of control tutorial until we honestly didn't have to give second thought to what button we were pressing to execute a particular move. By the time we wrapped up our play session, we were sliding between enemies' legs, tossing them into the air, calling in Elika to teleport-kick them, and thwacking away until they teetered on the edges of cliffs — just before we delivered a final blow that sending them plummeting. What was doubly impressive about the combat system was the fact that, according to Delbuquet, it continues to evolve steadily throughout the course of the game. We were already stringing together our own combos at this point; nothing felt canned."

Hugh Pickens writes "Traditionally the best treatment for post-traumatic stress disorder [PTSD] — being raped, narrowly escaping the collapse of the Twin Towers, or witnessing a buddy die on the battlefield — is to have the person relive the trauma using his or her imagination. Repeated exposure to the horror can desensitize individuals and help them stay calm enough to reprocess what happened and get beyond it. Now Clinical Psychologist Albert "Skip" Rizzo has developed a program that has had great success in treating returning troops from Iraq. A soldier with PTSD recounts what happened, and a therapist seated before a computer then creates an environment in the program Virtual Iraq that captures the essential elements of the episode. By donning special goggles, the soldier can see a reenactment and while the simulation starts off relatively tame over the course of several weeks, the therapist monitors the patient 's response and more elements of the episode are introduced until the individual can finally go through an intensely vivid recreation of it without being overpowered by terror. Other programs offered to treat PTSD include Virtual Airplane, Virtual Audiences, Virtual Heights, Virtual Storm, and Virtual Vietnam."

dotne writes "Microsoft has submitted Embedded OpenType (EOT) to W3C and a slimy campaign for EOT has been launched. EOT is a DRM layer on top of normal TrueType/Opentype files; EOT ties a font file to a certain web page or site and prevents reuse by other pages/sites. Microsoft's IE has supported EOT for years, but it has largely been ignored due to the clumsiness of having to regenerate font files when a page changes. Now that other browsers are moving to support normal TrueType and OpenType on the web (Safari, Opera, Mozilla, Prince), W3C is faced with a question: should they bless Microsoft's EOT for use on the web? Or, should they encourage normal font files on the web and help break Microsoft's forgotten monopoly?"
