Researchers Claim "Effectively Perfect" Spam Blocking Discovery 353

A team of computer scientists from the International Computer Science Institute in Berkeley, CA are claiming to have found an "effectively perfect" method for blocking spam. The new system deciphers the templates a botnet is using to create spam and then teaches filters what to look for. "The system ... works by exploiting a trick that spammers use to defeat email filters. As spam is churned out, subtle changes are typically incorporated into the messages to confound spam filters. Each message is generated from a template that specifies the message content and how it should be varied. The team reasoned that analyzing such messages could reveal the template that created them. And since the spam template describes the entire range of the emails a bot will send, possessing it might provide a watertight method of blocking spam from that bot."

Tynt Insight Is Watching You Cut and Paste 495

jerryasher writes "In recent weeks I've noticed that when I copy and paste text from Wired and other websites, the pasted text has had the URL of the original website appended to it. Cool, and utterly annoying, and how do I make that stop? Tynt Insight is a piece of Javascript that sends what you copy to Tynt's webservers and adds the backlinks. Tynt calls that a service for the site owner, many people call that a privacy invasion. Worse, there are some reports that it sends not just what you copy, but everything you select. And Tynt provides no opt outs. Not cookie-based, not IP-based, but stop-it-you-creeps-angry-phone-call-based. It ain't a pure useful service, and it ain't a pure privacy invasion. But I sure wish they'd go away or have had the decency never to start up in the first place. I block it on Firefox with Ghostery."

Mars Images Reveal Evidence of Ancient Lakes 128

Matt_dk writes "Spectacular satellite images suggest that Mars was warm enough to sustain lakes three billion years ago, a period that was previously thought to be too cold and arid to sustain water on the surface, according to research published today in the journal Geology. Earlier research had suggested that Mars had a warm and wet early history but that between 4 billion and 3.8 billion years ago, before the Hesperian Epoch, the planet lost most of its atmosphere and became cold and dry. In the new study, the researchers analysed detailed images from NASA’s Mars Reconnaissance Orbiter, which is currently circling the red planet, and concluded that there were later episodes where Mars experienced warm and wet periods."

Palm Pre and WebOS Get Native Gaming 49

rboatright writes "WebOS developers have been waiting, and with the 1.3.5 release, Palm's open source page suddenly listed SDL. Members of the WebOS internals team took that as a challenge and within 24 hours had a working port of Doom running in SDL on the Pre, in a webOS card. 48 hours later, they not only had Quake running, but had found in the latest LunaSysMgr the requirements to launch a native app from the webOS app launcher from an icon just like any other app. At the same time, the team demonstrated openGL apps running. With full native code support, with I/O available via SDL, developers now have a preview into Palm's future intent with regard to native code SDK's, and a hint of what's coming."

Saboteur Launch Plagued By Problems With ATI Cards 230

An anonymous reader writes "So far, there are over 35 pages of people posting about why EA released Pandemic Studios' final game, Saboteur, to first the EU on December 4th and then, after knowing full well it did not work properly, to the Americas on December 8th. They have been promising to work on a patch that is apparently now in the QA stage of testing. It is not a small bug; rather, if you have an ATI video card and either Windows 7 or Windows Vista, the majority (90%) of users have the game crash after the title screen. Since the marketshare for ATI is nearly equal to that of Nvidia, and the ATI logo is adorning the front page of the Saboteur website, it seems like quite a large mistake to release the game in its current state."

Linux Reaches 32% Netbook Market Share 389

christian.einfeldt writes "Linux netbooks have captured 32% of the global netbook market, says Jeff Orr, an analyst with consumer computer research firm ABI Research. The largest share of netbook sales is in the Asia-Pacific region, including Japan, Australia, and New Zealand, according to Orr. ABI's latest figures align with a statement by Dell executives in February of this year, to the effect that Linux netbooks comprised about 33% of Dell shipments of Dell Inspiron mini 9s netbooks. These data points cast doubt on claims by Microsoft that Windows XP has captured 98% of the netbook market (a figure Microsoft later revised to 93%). In an interview with DesktopLinux.com, Orr made clear that the 32% Linux netbook market share did not include either user-installed Linux or dual-boot systems, but was confined to just pre-installed Linux shipments."

Calling Video Professor a Scam 385

palmerj3 writes in to give some wider attention to a piece on Techcrunch today in which Michael Arrington reacts to Video Professor's desperate attempts to shut him up after he called Video Professor a scam in a piece syndicated by the Washington Post. As described by Arrington, the ways the company's site operates (differently depending on where a visitor comes from) are strongly reminiscent of the practices a Senate committee recently condemned. (Here is a detailed example of another, similar scam, from a not-naive victim. Video Professor's tactics sound even more deceptive.) Video Professor seems to react with belligerence, not to mention legal threats, towards any hint of criticism. Please share any direct experiences you have with this outfit.

Contest Winners Show Potential For Pressure-Sensitive Keyboard 129

Chris Harrison writes "About a month ago, Microsoft sent out prototype pressure sensitive keyboards to 40 international teams. They had four weeks to hack and cobble together some cool ideas. The innovation contest that centered around the keyboards released the winners last night (after a voting period Monday night at the ACM UIST conference). Some pretty neat ideas, ranging from pressure-sensitive password entry (Safelock), magnetic pens for cursor control (Hidden Forces), and even cool climbing (Rock Climbing) and land-deformation games (BallMeR)."

Dissolvable Glass For Bone Repair 168

gpronger writes "Sticks and Stones May Break My Bones, but Glass Will Certainly Mend Them! The old schoolyard ditty may be changed to reflect developments using metallic glass that will dissolve in situ instead of the traditional stainless steel or titanium hardware, which require removal by surgery once the bone has healed. Physics World reports that researcher Jörg Löffler at ETH Zurich has created an alloy of 60% magnesium, 35% zinc, and 5% calcium, molded in the form of metallic glass. Through rapid cooling, the alloy forms a molecularly amorphous glass that slowly dissolves over time, supporting the injury long enough for healing, then slowly dissolving away."

Ben Heck's PS3 Slim Laptop 84

We've occasionally discussed Ben Heckendorn's various console modifications, and he's now come out with a new one: a laptop version of the PS3 Slim. It has volume control buttons for the built-in speakers, and plenty of vents for cooling. The display is a 17" widescreen panel, and the Slim's hardware doesn't fill that much space in the case, so there's a neat little compartment for the power cord. Ben's blog post shows details of the laptop's construction.

Microsoft Tax Dodge At Issue In Washington State 681

newscloud writes "With Washington State facing a billion-dollar biennial budget deficit, the spotlight again shifts to Microsoft's software licensing office in Reno, Nevada. 'Although the majority of its software development is performed in Washington State, Microsoft records its estimated $18 billion in licensing revenue per year through a corporate office in Reno, Nevada where there is no licensing tax. Just by enforcing the state's existing tax law from 2008 onwards, we could reduce Washington's revenue shortfall by more than 70 percent. Alternately, we could pursue the entire $707 million from Microsoft's thirteen years of tax dodging and cover most of the expected deficit going forward.' We have discussed Microsoft's creative capitalism in the past."

FCC Backs Net Neutrality, Chairman's Full Speech Posted 270

ArmyofGnomes writes "FCC chairman Julius Genachowski delivered Monday on President Obama's promise to back 'net neutrality' — but he went much further than merely seeking to expand rules that prohibit ISPs from filtering or blocking net traffic by proposing that they cover all broadband connections, including data connections for smartphones. Genachowski stated: 'I understand the Internet is a dynamic network and that technology continues to grow and evolve. I recognize that if we were to create unduly detailed rules that attempted to address every possible assault on openness, such rules would become outdated quickly. But the fact that the Internet is evolving rapidly does not mean we can, or should, abandon the underlying values fostered by an open network, or the important goal of setting rules of the road to protect the free and open Internet. ... In view of these challenges and opportunities, and because it is vital that the Internet continue to be an engine of innovation, economic growth, competition and democratic engagement, I believe the FCC must be a smart cop on the beat preserving a free and open Internet.'"
