Condobolin sends in an update to the Australian government's ongoing efforts to implement ISP-level filtering. One of the hurdles they had to overcome was to build a system that would allow them to filter content without impairing other internet usage. A trial of the system has just concluded, and the results are positive — at least, for the government. Quoting: "More than half of the Internet service providers (ISPs) taking part in the Federal Government's ISP filtering trial have reported minimal speed disruptions or technology problems. Of the nine participating ISPs, iPrimus, Netforce, Webshield, Nelson Bay Online and OMNIconnect told ARN they had seen no slowdowns in Internet speeds or problems with the filtering solutions in place. Of the remaining four ISPs, Tech2U and Highway1 were unable to respond by time of publication while Unwired and Optus refused to comment. ... 'From a technical perspective we're more than confident that if the government decided to roll out a mandatory Internet filter based on or around an Australian Communications and Media Authority blacklist or subset thereof, then it can be done without any impact whatsoever to the speed of the Internet,' [said Webshield managing director Anthony Pillion]."

Necroloth and other readers sent in the story of Witricity's latest demo at the TED Global conference in Oxford, UK. The company is developing a system that can deliver power to devices without the need for wires. The idea is not new — electrical pioneers Thomas Edison and Nicola Tesla assumed that power would be delivered wirelessly. The BBC quotes the inventor behind Witricity's tech as saying that Tesla and Edison "...couldn't imagine dragging this vast infrastructure of metallic wires across every continent." eWeek Europe notes some hurdles the technology must overcome: "The 2007 experiment it is based on had an efficiency of only around 45 percent, but [Witricity's CEO] promised power delivered wirelessly would start out 15 percent more expensive than wires, and improve on that." Intel has also demonstrated wireless charging.

Michael J. Ross writes "Slow Web page loading can discourage visitors to a site more than any other problem, regardless of how attractive or feature-rich the given site might be. Consequently, many Web developers hope to achieve faster response times using AJAX (Asynchronous JavaScript and XML), since only portion(s) of an AJAX page need to be reloaded. But for many rich Internet applications (RIAs), such potential performance gains can be lost as a result of non-optimized JavaScript, graphics, and CSS files. Steve Souders — a Web performance expert previously at Yahoo and now with Google — addresses these topics in his second book, Even Faster Web Sites: Performance Best Practices for Web Developers." Read on for the rest of Michael's review.

An editorial by Rob Fahey looks into the possibility of game companies experimenting with modern 3D technology. Over the past decade, advances in the field have been enough for film studios to give 3D another shot, but significant price-related hurdles remain when considering individual consumers. Quoting: "[The approach presently favored by game makers] has actually been around for some time. It displays the image for the left eye, then the right eye, in quick succession on screen — while the glasses you wear close LCD 'shutters' over your eyes so that each eye only sees the appropriate image. If this is done fast enough, the brain sees no flicker — just a continuous, steady 3D image. The best thing about this final approach is that some televisions already exist which could, in theory, support it. No new display technology is required, but what you do need is a TV screen which can display twice the number of frames per second as a normal screen — since you now need one frame for each eye, where previously you had one frame for both eyes. You also need LCD glasses synched to the television's refresh rate for each viewer. All of this lies in the realms of being moderately plausible."

fiannaFailMan writes "An international plan to build a nuclear fusion reactor is being threatened by rising costs, delays and technical challenges. 'Emails leaked to the BBC indicate that construction costs for the experimental fusion project called Iter have more than doubled. Some scientists also believe that the technical hurdles to fusion have become more difficult to overcome and that the development of fusion as a commercial power source is still at least 100 years away. At a meeting in Japan on Wednesday, members of the governing Iter council will review the plans and may agree to scale back the project.' Iter will be a Tokamak device, a successor to the Joint European Torus (JET) in England. Meanwhile, an experiment in fusion by laser doesn't seem to be running into the same high profile funding problems just yet."

ausekilis writes "Many outlets are reporting that Time Warner has confirmed plans to spin off AOL. All that's left to deal with are a few financial hurdles, such as buying out Google's 5% stake in AOL. The interesting part of the story is that both AOL's CEO and Time Warner's CEO said effectively the same thing, that AOL will be better off as an independent unit, as opposed to 'a cog in the Time Warner wheel.' Interesting to note that when they originally merged, the idea was for AOL to be a one-stop shop for all your internet goods. Makes you wonder what would have happened if Time Warner had invested in AOL as an exclusive media outlet for movies, TV, music, etc. Perhaps AOL would have regained some speed and become the prominent household name it once was, instead of being that company who sent us all the free coasters."

eldavojohn writes "A policy from the Bush era seen as a hurdle to the government prosecuting companies under antitrust laws has been withdrawn by Obama's Department of Justice. From the article: 'The DOJ's Antitrust Division has withdrawn a September report that "raised too many hurdles to government antitrust enforcement and favored extreme caution" toward antitrust enforcement action, the DOJ said. The change in policy could mean that the department looks harder at the actions of technology vendors such as Google, Oracle and IBM, as detractors have raised antitrust concerns about all three in recent months.' You may recall that Google has come under some antitrust scrutiny recently and the pressure may have just gotten a little more intense."

snydeq writes "Red Hat CEO Jim Whitehurst questioned the relevance of Linux on the desktop, citing several financial and interoperability hurdles to business adoption at a panel on end-users and Linux last night at the OSBC. 'First of all, I don't know how to make money on it,' Whitehurst said, adding that he was uncertain how relevant the desktop itself will be in five years given advances in cloud-based and smartphone computing, as well as VDI. 'The concept of a desktop is kind of ridiculous in this day and age. I'd rather think about skating to where the puck is going to be than where it is now.' Despite increasing awareness that desktop Linux is ready for widespread mainstream adoption, fellow panelists questioned the practicality of switching to Linux, noting that even some Linux developers prefer Macs to Linux. 'There's a desire [to use desktop Linux],' one panelist said, 'but practicality sets in. There are significant barriers to switching.'"

IEEE Spectrum is running a feature about the progress of game AI, and how it's helping to drive AI development in general. They explore several of the current avenues of research and look at potential solutions to some of the common problems. "The trade-off between blind searching and employing specialized knowledge is a central topic in AI research. In video games, searching can be problematic because there are often vast sets of possible game states to consider and not much time and memory available to make the required calculations. One way to get around these hurdles is to work not on the actual game at hand but on a much-simplified version. Abstractions of this kind often make it practical to search far ahead through the many possible game states while assessing each of them according to some straightforward formula. If that can be done, a computer-operated character will appear as intelligent as a chess-playing program--although the bot's seemingly deft actions will, in fact, be guided by simple brute-force calculations."

Daengbo writes "While I live in S.Korea and have virtually unlimited bandwidth in and out of the country, not all my Asian friends are so lucky. Many of the SE Asian and African countries have small international pipes. Even when a user has a high-speed local connection, downloads from abroad will trickle in. Bittorrent clients apparently don't prioritize other users on the same ISP or at least in the same country. Why is that? Is it difficult to manage? If I were to write a plug-in for, say, Deluge, what hurdles would I be likely to come across? If this functionality is available in other clients or through plug-ins, please chime in."

An anonymous reader writes "After attending DEFCON in August and seeing the overwhelming interest in this book, I was eager to dive into The IDA Pro Book by Chris Eagle. Chris Eagle's team, School of Root, won the 'Capture the Flag' event at DEFCON this year and Chris gave a presentation on CollabREate, a tool that integrates with IDA Pro to allow collaboration in reverse engineering (RE). All of that — together with the fact that the book sold out — screamed that this book should quickly make it to the top of my list." This review originally appeared on The Ethical Hacker Network.

Hugh Pickens writes "While it may seem unlikely that single-celled organisms could be trained to salivate like Pavlov's dog at the sound of a bell, researchers say that bacteria can 'learn' to associate one stimulus with another by employing molecular circuits. This raises the possibility that bioengineers could teach bacteria to act as sentinels for the human body, ready to spot and respond to signs of danger. As with Pavlov's dog, the bacteria in the model learn to build stronger associations between the two stimuli the more they occur together. Now called Hebbian learning, it's often expressed as a situation in which 'neurons that fire together wire together.'" (More below.)

least_weasel writes "An article on Ars Technica reveals Mozilla's intention to create and release a plugin for Internet Explorer that would allow the often-criticized IE to utilize some of the cooler rendering code developed for Firefox. The current WIP focuses on rendering using HTML5 standards, but the plans seem to be more ambitious than just fixing this one small piece of IE. The article covers some of the plans, hurdles, and potential benefits. It also spills the beans on the code name for the project: Screaming Monkey."

A few weeks ago, you asked questions of Lt. Col. John Bircher, head of an organization with a difficult-to-navigate name: the U.S. Army Computer Network Operations (CNO)-Electronic Warfare (EW) Proponent's Futures Branch. Lt. Col. Bircher has answered from his perspective, at length, not just the usual 10 questions, but several more besides. Read on for his take on cyberwar, jurisdiction, ethics, and more.

GamerGirll1138 writes to tell us Next-gen has an amusing walk down memory lane with their history of copy protection. There have been some crazy schemes over the years to ensure that you paid for your software, everything from super-secret decoder rings to ridiculous document checks. "With bandwidth expanding and more and more games publishers exploring digital distribution, there's little doubt that we're entering a new phase in the history of copy protection and those who would defeat it. What's more, the demand for games as a chosen form of entertainment has never been higher. All this considered, it's impossible to believe that the cat-and-mouse game of piracy and copy protection will not reach new levels of intensity, with new technologies deployed on each side, and that some of them will surely create new hurdles for even those who simply wish to purchase and play the newest games. Ah, for the heady days of the code wheel."

Newscloud brings us news of a startup called E-Fuel promising to ship a home-brew ethanol plant, the size of a washer-dryer, for under $10,000 by the end of this year. We've had plenty of discussions about $1/gal. fuel — these guys want to let you make it at home. The company says it plans to develop a NAFTA-enabled distribution network for inedible sugar from Mexico at 1/8th the cost of trade-protected sugar, to use as raw material for making ethanol. A renewable energy expert from UC Berkeley is quoted: "There's a lot of hurdles you have to overcome. It's entirely possible that they've done it, but skepticism is a virtue."

The New York Times reports on a deal between MySpace and three of the four major music labels to develop a new music website. Users will be able to stream songs for free, purchase downloadable tracks, and (possibly) pay a flat monthly fee for unlimited access. From the Times: "Exact terms of the deal and details about the new site, like prices for downloaded music tracks, were not disclosed. But MySpace did say the site would offer songs free of digital rights management software or D.R.M., which is used to prevent illicit copying but can create technical hurdles for buyers. The songs would be playable on any portable music device, including Apple's iPod. For the music industry, the deal is partly born of desperation. In the face of widespread, escalating online piracy, music sales dropped to $11.5 billion in 2006 from a peak in 1999 of nearly $15 billion."

An anonymous reader writes to mention Nature is reporting that scientists have discovered a much more efficient way to use silicon to convert heat into electricity. This offers the possibility of many different applications including possibly charging your portable electronics just by wearing them close to your skin. "The concept of converting waste heat into electricity isn't exactly new, but it never really materialized due to efficiency hurdles. Now, scientists from the U.S. Department of Energy's (DOE) Lawrence Berkeley National Laboratory (Berkeley Lab) and the University of California at Berkeley think they may have found a key [to] increase the conversion efficiency by a factor of 100."

lgmac writes "A new survey on the results of Enterprise use of virtualization shows that the process is seeing wide and appreciative use. Technical hurdles are obviously the biggest problem facing corporate IT shops. Just the same, political squabbles among IT staffers fighting for turf after being forced to work together in new ways seems to be a going concern as well. 'Technical woes rank higher--to be expected when CIOs deploy a new technology such as virtualization. However, the politics pain many of you. Remember, virtualization not only asks people to cede some control over their physical server kingdoms, but also asks IT experts from different realms to work more closely together.'"
