Submission + - B&N Pummels Microsoft Patent Claims with Prior ( 1

itwbennett writes: "As Slashdot readers will recall, Barnes & Noble is being particularly noisy about the patents Microsoft is leveraging against the Nook. Now the bookseller has filed a supplemental notice of prior art that contains a 43-page list of examples it believes counters Microsoft's claim that Nook violates five of Microsoft's patents. 'The list of prior art for the five patents that Microsoft claims the Nook infringes is very much a walk down memory lane,' says blogger Brian Proffitt. 'The first group of prior art evidence presented by Barnes & Noble for U.S. Patent No. 5,778,372 alone lists 172 pieces of prior art' and 'made reference to a lot of technology and people from the early days of the public Internet... like Mosaic, the NCSA, and (I kid you not) the Arena web browser. The list was like old home week for the early World Wide Web.'"

Submission + - Difficult Campground WIFI design 1

MahlonS writes: "I am a retired network hack wintering in my RV in a campground in southern GA. 3 years ago I reconfigured the wifi system to a marginal working ability, It now needs a serious upgrade, prompted by a new cable net connection replacing a DSL. 5 dual radio HP access points connect to a 6th via single or double radio hops in heavily wooded space. The main connect is an old Cisco router. Burying wire is frowned upon, due to shallow utilities. Since I'm not up on current wifi tech, are there solutions out there that would make this system work much better?"

Submission + - Intel Preps Firmware Upgrade to Address SSD Bug (

MojoKid writes: "Semi-good news for Intel 320 Series SSD owners who might be suffering from the notorious 8MB bug. The Santa Clara chip maker is fully aware of the problem and is promising a new firmware update that will supposedly stomp out the annoying bug for good. "Intel has been investigating the "Bad Context 13x" error as seen on select Intel SSD 320 Series drives," Intel said in a statement. The company has been able to reproduce the the anomaly and has noted that it's fixable. As it stands, Intel is in the processing of validating the new firmware, though stopped short of announcing when it will be made available to the public."

Submission + - Time travel proved impossible with a photon (

An anonymous reader writes: In order to time travel all you have to do is manage to travel faster than the speed of light. It sounds quite simple when you put it like that, but the tough bit is managing to go fast enough to break through that speed barrier, a barrier that scientists now believe they have proved is impossible to exceed.

Professor Du Shengwang, physicist and head of a Hong Kong University Science and Technology research team, decided to prove that time travel was impossible once and for all. He did this by managing to measure the speed of a single photon in a vacuum using controllable waveforms. A photon is the basic unit of light and has no mass, it is also known as an elementary particle.

The experiment is relevant because for the past 10 years it has been thought optical pulses may be able to travel faster than light under specific circumstances. This is called superluminal. However, it was later proved wrong, but left scientists with questions about how fast a photon could travel as it would be the one particle that could potentially break the speed of light barrier.

Shengwang’s work has proved that is definitely not the case and Eintein’s theory that light is the “traffic law of the universe” still holds up as true. The research also goes beyond just proving light speed is the upper limit and offers insights into the transmission of quantum information.

Submission + - PS3 'Strong Contender' to Overtake Xbox 360 (

donniebaseball23 writes: Xbox 360 has been having an incredible year so far in 2011, but on a global scale Sony's PS3 is still gaining ground. In fact, this year PS3 has outpaced Xbox 360 by 10% worldwide, analysts have pointed out. While the Wii has clearly won the race for this console generation, the battle for second place is neck and neck, and PS3 has a good shot of overtaking Xbox 360. "As for second place, as far as the hardcore market is concerned, I'd say PS3 is a strong contender for that position," commented M2 Research analyst Billy Pidgeon.

Submission + - Why IT's Control-Freak Days Are Coming to an End (

GMGruman writes: "Many users consider IT to be an annoyance on the road to getting their job done. IT considers itself the defender of the realm, making sure all the technologies are running exactly as they should, everything is managed and accounted for, and security threats are constantly deflected. And IT usually considers users to be idiots or, at best, naive children who need to be controlled. But today, there's a big change afoot, driven by the consumerization of technology, as heralded by the iPhone and cloud computing. Columnist Bob Lewis explains why IT has to change from being a control organization to a stewardship organization — else see itself usurped over time by tech-savvy business users."

There is at least some support in the Senate for the RC guys with bill S.223. There is a section which will prevent the FAA from regulating model aircraft given the meet a certain criteria: (1) IN GENERAL.--Notwithstanding any other provision of law relating to the incorporation of unmanned aircraft systems into FAA plans and policies,, including this section, the Administrator shall not promulgate any rules or regulations regarding model aircraft or aircraft being developed as model aircraft if such aircraft is-- (A) flown strictly for recreational, sport, competition, or academic purposes; (B) operated in accordance with a community-based set of safety guidelines and within the programming of a nationwide community-based organization; and (C) limited to not more than 55 pounds unless otherwise certified through a design, construction, inspection, flight test, and operational safety program currently administered by a community-based organization. (2) MODEL AIRCRAFT DEFINED.--For purposes of this subsection, the term ``model aircraft'' means a nonhuman-carrying (unmanned) radio-controlled aircraft capable of sustained flight in the atmosphere, navigating the airspace and flown within visual line-of-sight of the operator for the exclusive and intended use for sport, recreation, competition, or academic purposes."

Submission + - White House wants to make IP infringement a felony ( 2

Shikaku writes: "The White House today proposed sweeping revisions to U.S. copyright law, including making "illegal streaming" of audio or video a federal felony and allowing FBI agents to wiretap suspected infringers.

In a 20-page white paper (PDF), the Obama administration called on the U.S. Congress to fix "deficiencies that could hinder enforcement" of intellectual property laws."

Submission + - Fukushima - A Simple Explanation 1

Stenchwarrior writes: Along with reliable sources such as the IAEA and WNN updates, there is an incredible amount of misinformation and hyperbole flying around the internet and media right now about the Fukushima nuclear reactor situation. In the BNC post Discussion Thread – Japanese nuclear reactors and the 11 March 2011 earthquake (and in the many comments that attend the top post), a lot of technical detail is provided, as well as regular updates. But what about a layman’s summary? How do most people get a grasp on what is happening, why, and what the consequences will be?

Submission + - 40th Anniversary of the Computer Virus (

Orome1 writes: This year marks the 40th anniversary of Creeper, the world’s first computer virus. From Creeper to Stuxnet, the last four decades saw the number of malware instances boom from 1,300 in 1990, to 50,000 in 2000, to over 200 million in 2010. Besides sheer quantity, viruses, which were originally used as academic proof of concepts, quickly turned into geek pranks, then evolved into cybercriminal tools. By 2005, the virus scene had been monetized, and virtually all viruses were developed with the sole purpose of making money via more or less complex business models.
