All Solid State Drives Suffer Performance Drop-off 150

Lucas123 writes "The recent revelation that Intel's consumer X25-M solid state drive had a firmware bug that drastically affected its performance led Computerworld to question whether all SSDs can suffer performance degradation due to fragmentation issues. It seems vendors are well aware that the specifications they list on drive packaging represent burst speeds when only sequential writes are being recorded, but after use performance drops markedly over time. The drives with better controllers tend to level out, but others appear to be able to suffer performance problems. Still not fully baked are benchmarking standards that are expected out later this year from several industry organizations that will eventually compel manufacturers to list actual performance with regard to sequential and random reads and writes as well as the drive's expected lifespan under typical conditions."

StarCraft II Beta Signups Open 123

motang writes "StarCraftWire reports that Blizzard has started taking beta sign-ups for StarCraft II. Quoting: 'Interested parties must simply visit their Battle.net profile page, choose to opt-in for the beta, and re-submit their current system specs by way of a small downloadable piece of software.' Blizzard's Chris Sigaty said in an interview, 'As with previous betas for our real-time strategy games, the StarCraft II beta test will be multiplayer only, and players will have access to all three races — terrans, protoss, and zerg — and all of their units. We'll include a selection of multiplayer maps, but they won't necessarily include all of the maps that will be in the final version of the game. We're making some great progress on the single-player campaign, but we don't plan to do a public beta since we want to keep the story under wraps until the game's out.'"

Hadrosaur Proteins Sequenced 81

jd writes "In a follow-up study to the one on proteins found in a T. Rex bone, the team responsible for the T. Rex study sequenced proteins found in an 80-million year old Hadrosaur fossil. According to the article, the proteins found confirm the results of the T. Rex study, proving that what was found in T. Rex was not a result of modern contamination, as had been claimed by skeptics, but was indeed the genuine thing: real dinosaur protein. Furthermore, despite the new fossil being 12 million years older, they claim they got more out — eight collagen peptides and 149 amino acids from four different samples. This, they say, places the Hadrosaur in the same family as T. Rex and Ostriches, but that not enough was recovered to say just how close or distant the relationship was."

FDA Could Delay Adult Stem Cell Breakthroughs 261

from the culture-club dept.
destinyland writes "A Colorado medical advocate says, 'The FDA contends that if one cultures stem cells at all...then it's a prescription drug,' in arguing that revolutionary new treatments could be delayed by 20 years — even using cells extracted from your own body. According to the FDA, even therapies that simply re-inject your body's adult stem cells could be prohibited without five years of clinical trials and millions of dollars of research. How useful are cultured stem cells? 'In animal models, they routinely cure diabetes.'"

+ - Comcast blocking BitTorrent traffic

Submitted by Phanatic1a
Phanatic1a (413374) writes "P2P-oriented blog Torrentfreak claims that Comcast has now started to sever their customers' BitTorrent connections: "It is reported that Comcast is using an application from Sandvine to throttle BitTorrent traffic. Sandvine breaks every (seed) connection with new peers after a few seconds if it's not a Comcast user. This makes it virtually impossible to seed a file, especially in small swarms without any Comcast users. Some users report that they can still connect to a few peers, but most of the Comcast customers see a significant drop in their upload speed.""

+ - New Cable Modem to Triple Internet Speed

BlueMorpho writes "That's right-optical fiber-to-the-home service had previously offered the fastest available connection for residential Internet. The best-known example is the FiOS service from Verizon Communications, which peaks at 50 megabits per second.

But the cable industry has recently taken the wraps off new cable modem technology that exceeds the FiOS speed by a factor of more than three. Called the Data Over Cable Service Interface Specification (DOCSIS) 3.0, it allows data throughput of as much as 160 megabits.

mikemuch writes "With the release of the demo for Lost Planet: Extreme Condition, the public gets its first look at what DirectX 10 has to offer, and it's not pretty. Jason Cross at ExtremeTech has benchmarks that reveal shortcomings in the demo and particularly in ATI's cards/drivers. ATI claims they weren't given code early to optimize for. Nvidia doesn't fare too much better when all the eye candy is turned up. The game also needs to be re-interfaced for the PC, as opposed to a wholesale port of the Xbox version. Stick this one back in the oven, it's not done."

Adapt. Enjoy. Survive.
