Pushing the speed limits of quantum memory

// March 10th, 2010 // No Comments » // Tech News

It feels like quantum computers have barely been invented, and scientists are already testing how extensible the current technology is. A paper published in Nature Photonics this week describes how researchers are beginning to push the bandwidth limits of quantum memory. Using photon pulses and cesium vapor has provided bandwidths on par with broadband connections, rates 100 times those of other quantum memory systems currently being tested. However, the system’s efficiency is still very low, and advances will have to be made in other fields before it can be improved. Since many quantum computing implementations operate on photons, a quantum memory that doesn’t involve converting photons into other media, like electrical pulses, would be ideal. Unfortunately, current photon-based media suffers from problems with storage time, retrieval efficiency, and bandwidth. The paper tackles the last issue, as current quantum systems are limited to a data rate of a few megahertz at most. Read the comments on this post

p2pnet view P2P:- Hi all: I’ve just turned down a cash offer, plus a promise of royalties, for p2pnet. I turned it down because it would’ve meant a 100% buyout. The new owner would’ve taken exclusive control of the content, disbarring me from making any use of it in the future – copyrighting it, in other words. Obviously, I couldn’t accept such a condition. p2pnet will stay online as-is, and I’ll add to it as and when I can while my wife and I develop other sources of income. I’ll also continue to work on a2f2a.com Cheers!

Cellcos hoping to cash in on iPad with 3G/4G mobile hotspots

// March 10th, 2010 // No Comments » // Tech News

Though the 3G-equipped version of the iPad will only be able to get data services from AT&T, Verizon apparently sees the introduction of Apple’s tablet device as “an opportunity” for the company to sell data services. A supposed internal sales memo published by Engadget reveals Verizon’s plan to push its MiFi mobile hotspot for the WiFi-only version of the iPad, which will be available April 3 . The memo points out that the WiFi + 3G iPad won’t go on sale for at least a few weeks after the WiFi model, costs $130 more, and can only get service through AT&T, which the memo describes as “an overloaded network with limited coverage.” Ouch. To be fair, the extra $130 includes GPS hardware in addition to the 3G radios, and AT&T continues to make improvements to its network. But, if you don’t want to wait, don’t want to pay extra, or just don’t want to use AT&T service, Verizon has a point—a mobile hotspot like the MiFi (which can connect up to 5 devices at once) can make a good alternative. A MiFi 2200 from Verizon will run you $50 with current promotions and a two-year contract; without a contract expect to pay about $250. However, Verizon’s plans aren’t as generous or affordable as the data options AT&T offers for the iPad. Through AT&T, you’ll pay $15 per month for up to 250MB of data or $30 per month for unlimited via AT&T, and those plans don’t require a contract. With Verizon, you’ll pay $40 per month for up to 250MB, or $60 per month with a 5GB cap. Prepaid, non-contract options start at $15 per day with a 75MB limit. Like AT&T, however, your plan also includes free access to Verizon WiFi hotspots. Sprint offers a branded MiFi 2200 as well, though you can get it free after a $50 mail-in rebate. The company only offers one data plan, though: $60 per month with a 5GB cap (and a 300MB cap on roaming). Sprint also offers the Sierra Wireless Overdrive 4G/3G hotspot for those in an area with WiMAX coverage. Though it costs $100 after rebate, for the same $60 a month you’d get unlimited 4G data and 5GB of 3G data. For a 4G-only option, you can go directly through Clear to get a 4G USB modem and a Clear Spot WiFi adapter that works with up to eight devices for under $200 total. Data plans start at $40 per month for 4G-only access, though bundles with home service or 3G fall-back are also available. Other combinations of mobile data modems and/or mobile hotspots are also possible, and it’s probably worth it to check with the provider in your area to see what options are available. Despite the extra cost of the WiFi + 3G iPad and the associated data plans, you’re not likely to find a cheaper alternative. But going this route means you’ll have data access for other devices, such as a laptop, iPod touch, or Nintendo DSi, and can serve data to multiple devices at the same time. The extra flexibility may fit your particular needs and justify the extra cost. Read the comments on this post

Free wireless broadband plan is déjà vu all over again

// March 10th, 2010 // No Comments » // Tech News

As part of the grand hoopla-fest building up to the release of the Federal Communications Commission’s National Broadband Plan this month, the agency hosted a Digital Inclusion Summit at Washington, DC’s Newseum on Tuesday. Co-sponsored with the Knight Foundation, during the course of the event the FCC disclosed more components of The Plan. These include recommending the creation of a Digital Literacy Corps “to conduct skills training and outreach in communities with low rates of adoption,” and tapping into the agency’s Universal Service Fund to subsidize broadband for low income people. But what really got our attention was this: the NBP will ask the government to “consider use of spectrum for a free or very low cost wireless broadband service.” That’s odd, we thought, since the FCC and Congress have been considering such an idea for years.

Scientific examination of the subject has found that as the use of porn increases, the rate of sex crimes goes down The Scientist Most people have seen it, and have a strong opinion about it. Many of those opinions are negative—some people argue that ready access to pornography disrupts social order, encouraging people to commit rape, sexual assault, and other sex-related crimes. And even if pornography doesn’t trigger a crime, they say, it contributes to the degradation of women. It harms the women who are depicted by pornography, and harms those who do not participate but are encouraged to perform the acts depicted in it by men who are acculturated by it. Many even adamantly believe that pornography should become illegal. Alternatively, others argue that pornography is an expression of fantasies that can actually inhibit sexual activity, and act as a positive displacement for sexual aggression. Pornography offers a readily available means of satisfying sexual arousal (masturbation), they say, which serves as a substitute for dangerous, harmful, and illegal activities. Some feminists even claim that pornography can empower women by loosening them from the shackles of social prudery and restrictions. But what do the data say? Over the years, many scientists have investigated the link between pornography (considered legal under the First Amendment in the United States unless judged ‘obscene’) and sex crimes and attitudes towards women. And in every region investigated, researchers have found that as pornography has increased in availability, sex crimes have either decreased or not increased. German publisher in row with Apple over pin-ups in iPhone app Guardian The International Federation of the Periodical Press (FIPP) is considering making a complaint to Apple over the computer firm’s request that German publisher Springer censor the naked girls on one of its iPhone apps. Springer-owned tabloid Bild’s “Shake the Bild Girl” app allows iPhone users to undress a model. Each time the user shakes the phone, the girl strips an item of her clothing. While Bild features naked women daily in its pages, Apple ruled that the girls in its iPhone app should wear bikinis. The Association of German Magazine Publishers (VDZ) asked FIPP last week to approach Apple over the issue. FIPP is debating the issue, but has no further comment at the moment. Actor Corey Haim dies from drug overdose CBC Los Angeles police have confirmed Canadian actor Corey Haim died at age 38 early Wednesday, apparently from an accidental drug overdose. The LAPD said Haim was taken to a Burbank hospital, where he was pronounced dead at 2:15 a.m. local time, according to the L.A. coroner’s office. Police said Haim had been living in an apartment in North Hollywood. His mother Judy was said to have been with him in the apartment, and she called 911. Limewire Hooks Up with AVG, Promises Virus Free P2P Maximum PC Surely you are aware the p2p networks are crawling with nasty malware. It’s almost enough to make you go elsewhere for your copyrighted public domain content. The MPAA and RIAA are of the opinion that people running torrents are a bunch of pirates that deserve what’s coming to them. The makers of Limewire, however, feel differently and have licensed the AVG antivirus engine to provide real-time scanning of downloaded files. Limewire accesses both the Gnutella and BitTorrent protocols. The pro version of the software will be the one getting the security upgrades. Users of the free edition will still be on their own. Files scanned with the integrated scanner will be labeled as ‘Protected by AVG’. The software will make no distinction between legal and illegal files. Privacy Protection Needed As Smart Grid Arrives EFF Privacy advocates are warning that “smart meters” intended to precisely measure and control home electrical consumption could erode the privacy of daily life unless regulators limit data collection and disclosure. In a joint filing yesterday, the Center for Democracy & Technology (CDT) and the Electronic Frontier Foundation (EFF) urged the California Public Utilities Commission (PUC) to adopt rules to protect the privacy and security of consumers’ energy-usage information. The Samuelson Law, Technology & Public Policy Clinic at UC Berkeley School of Law drafted the comments for CDT. Smart meters being installed now in California will collect 750 to 3,000 data points a month per household. This detailed energy usage data can indicate whether someone is at home or out, entertaining guests, or using particular appliances. Marketers and others may seek such data. To head off misuse of the information, CDT and EFF urged the California PUC to adopt comprehensive privacy standards for the collection, retention, use and disclosure of consumers’ household energy data. Pa. woman accused of recruiting jihadists online Washington Post A suburban woman “desperate to do something” to help suffering Muslims has been accused of using the Internet to recruit jihadist fighters and help terrorists overseas, even agreeing to move to Europe to try to kill a Swedish artist, prosecutors said Tuesday. Authorities said the case shows how terror groups are looking to recruit Americans to carry out their goals. A federal indictment charges that Colleen R. LaRose, who called herself JihadJane and Fatima LaRose online, agreed to kill the Swede on orders from the unnamed terrorists and traveled to Europe to carry out the killing. It doesn’t say whether the Swede was killed, but LaRose was not charged with murder. New MySpace chiefs plan major relaunch Telegraph In their first interview since the shock departure of Owen Van Natta, MySpace’s former chief executive, Mike Jones and Jason Hirschorn, the company’s new co-presidents, say they will be ready to ‘win back old users’ by the end of this year. While both executives refused to be drawn on the reasons surrounding Mr Van Natta’s sudden exit, they admitted that they would ‘now be innovating at an accelerated pace’. It was felt that Mr Van Natta had failed to develop and implement new services quick enough, according to a senior digital source close to the company who spoke to The Telegraph at the time. - … .. … and identi.ca More First they ignore you, then they laugh at you, then they fight you, then you win ~ Mahatma Gandhi March, 2010 Use free p2pnet newsfeeds for your site.

Is BitStalker an(other) ACTA prop?

// March 10th, 2010 // No Comments » // p2p

p2pnet view Freedom | P2P:- Is a new application developed by PolyCipher, a Comcast, Time Warner Cable  and Cox joint venture, evidence of ISP support for ACTA and a global three-strikes law? That’s what Soulskill wonders in a Slashdot post. “I was scanning conference proceedings to come up with ideas for a reading group I run at my workplace, and I noticed an interesting paper from the new IEEE WIFS forensics conference “, he says, continuing: “Researchers from the University of Colorado have published a technique for tracking BitTorrent users (PDF) by joining and actively probing torrent swarms using low-cost cloud computing services.” They claim their methods “allowed them to monitor the entire Pirate Bay torrent set for as little as $13/mo using EC2″, says the post, adding: ” But that’s not even the interesting part. Their work appears to have been ‘funded in part through gifts from PolyCipher’ — a broadband ISP consortium . “That’s right; three major national ISPs funded this round of BitTorrent tracking research, not the MPAA/RIAA?” Says the abstract to BitStalker: accurately and efficiently monitoring BitTorrent traffic > > > BitTorrent is currently the most popular peer-to-peer network for file sharing. However, experience has shown that Bit-Torrent is often used to distribute copyright protected movie and music files illegally. Consequently, copyright enforcement agencies currently monitor BitTorrent swarms to identify users participating in the illegal distribution of copyrightprotected files. These investigations rely on passive methods that are prone to a variety of errors, particularly false positive identification.” To mitigate the potential for false positive peer identification, we investigate the feasibility of using active methods to monitor extremely large BitTorrent swarms. We develop an active probing framework called BitStalker that identifies active peers and collects concrete forensic evidence that they were involved in sharing a particular file. We evaluate the effectiveness of this approach through a measurement study with real, large torrents consisting of over 186,000 peers. We find that the current investigative methods produce at least 11% false positives, while we show that false positives are rare with our active approach. Says the conclusion: “BitStalker collects concrete evidence of peers’ participation in file sharing in a way that is robust to tracker pollution, highly accurate, and efficient. “In contrast, the past and present investigative monitoring strategy consists of tracker server queries and ICMP ping probes. While this method is simple, it is also prone to a variety of significant errors, especially false positive identification, since this monitoring technique does not verify participation in the file sharing. We present an alternative monitoring strategy based on actively probing the list of suspected peers to obtain more conclusive evidence of participation in the file sharing. “There are several aspects of our approach that warrant additional attention. In particular, a specific definition of what constitutes ‘evidence’ in the context of file sharing across various legal systems should be explored. Also, the general legal issues that this type of monitoring exposes should also be investigated further.” Stay tuned.

Street Fighter IV: as good as you can expect on the iPhone

// March 10th, 2010 // No Comments » // Tech News

Street Fighter IV is now available on Apple’s App Store; you can pick it up right now for $10 if you’d like to see what Capcom can do with Apple’s hardware. Capcom also threw quite the party at GDC, allowing the press and community some hands-on time with the game. After playing for about 15 minutes, the verdict is in: this is about as good as you can expect from a fighting game on the iPhone. It looks great, but you’ll still be fighting the controls As a tech demo it’s amazing. The characters are large and detailed, and they move fluidly with grace. Many people enjoyed simply watching others play the game; this is one of the prettiest portable fighting games out there. The problem is simple: the iPhone doesn’t have any actual buttons. Many gamers are snobs about the input for their Street Fighter experience, playing with only arcade-quality parts. Going from my home set-up to virtual buttons on the iPhone screen took a while to get used to. I was able to pull off the dragon punches and fireballs after a while, but the game never felt good to me. It never felt like a game I could sit down and play for hours. The iPhone just isn’t set up for this kind of game, and Street Fighter IV felt like someone trying to prove that it could be done. The question they should have asked was should it be done. A good iPhone game takes advantage of what the hardware can do well and works around what it does poorly. Street Fighter IV is simply a graphical curiosity. Read the comments on this post

Bluster and threat, Sun and Apple

// March 10th, 2010 // No Comments » // p2p

p2pnet view P2P:- Bluster and threat are essential tools of business, says Jonathan Schwartz, former CEO of Sun Microsystems. His observation comes in his personal blog when he has a serious go at Steve Jobs and Bill Gates, as Slashdot points out. In 2003, “after I unveiled a prototype Linux desktop called Project Looking Glass , Steve called my office to let me know the graphical effects were “stepping all over Apple’s IP”, says Schwartz, going on > > > If we moved forward to commercialize it, “I’ll just sue you. My response was simple. “Steve, I was just watching your last presentation, and Keynote looks identical to Concurrence – do you own that IP?” Concurrence was a presentation product built by Lighthouse Design, a company I’d help to found and which Sun acquired in 1996. Lighthouse built applications for NeXTSTEP, the Unix based operating system whose core would become the foundation for all Mac products after Apple acquired NeXT in 1996. Steve had used Concurrence for years, and as Apple built their own presentation tool, it was obvious where they’d found inspiration . “And last I checked, MacOS is now built on Unix. I think Sun has a few OS patents, too.” Steve was silent. And that was the last I heard on the topic. Although we ended up abandoning Looking Glass, Steve’s threat didn’t figure into our decision (the last thing enterprises wanted was a new desktop – in hindsight, exactly the wrong audience to poll (we should’ve been asking developers, not CIO’s)). As in life, says Schwartz, “bluster and threat are commonplace in business – especially the technology business”, continuing: ” So that interaction was good preparation for a later meeting with Bill Gates and Steve Ballmer. They’d flown in over a weekend to meet with Scott McNealy, Sun’s then CEO – who asked me and Greg Papadopoulos (Sun’s CTO) to accompany him. As we sat down in our Menlo Park conference room, Bill skipped the small talk, and went straight to the point, ‘Microsoft owns the office productivity market, and our patents read all over OpenOffice.’ OpenOffice is a free office productivity suite found on tens of millions of desktops worldwide. It’s a tremendous brand ambassador for its owner – it also limits the appeal of Microsoft Office to businesses and those forced to pirate it. Bill was delivering a slightly more sophisticated variant of the threat Steve had made, but he had a different solution in mind. ‘We’re happy to get you under license.’ That was code for ‘We’ll go away if you pay us a royalty for every download’ – the digital version of a protection racket. “But fearing this was on the agenda, we were prepared for the meeting. Microsoft is no stranger to imitating successful products, then leveraging their distribution power to eliminate a competitive threat – from tablet computing to search engines, their inspiration is often obvious (I’m trying to like Bing, I really am). So when they created their web application platform, .NET, it was obvious their designers had been staring at Java – which was exactly my retort. ‘We’ve looked at .NET, and you’re trampling all over a huge number of Java patents. So what will you pay us for every copy of Windows?’ Bill explained the software business was all about building variable revenue streams from a fixed engineering cost base, so royalties didn’t fit with their model … which is to say, it was a short meeting.” With the above, and the rest of the post, in mind, Schwartz “has already hinted at plans to write a book”, says Slashdot.

Nanotubes help create thermopower waves

// March 10th, 2010 // No Comments » // Tech News

A paper published in Nature Materials this week details a new method for using nanotubes to generate significant amounts of power, at least for their size. When multi-walled carbon nanotubes are covered with a material that produces an exothermic reaction, the nanotubes help conduct the heat in one focused direction. To the apparent surprise of the researchers, this created an electrical pulse, a quick surge of power, that could be put to a number of uses. When you couple a heat-activated material with exothermically-reactive chemicals, it’s theoretically possible to create self-propagating waves of heat. However, there are a couple of problems with implementing systems like these. The waves generally propagate in all directions, which is not terribly efficient for heat- or power-generating purposes. Furthermore, materials that both prevent the wave of the pulse from scattering and can stand up to a large amount of heat are fairly rare. Read the comments on this post

Whatever happened to ‘courts of record’?

// March 10th, 2010 // No Comments » // p2p

p2pnet view P2P:- “Now that we finally have the technology to know and share what is really going on in our courts, the parties and/or the courts seem bound and determined to take that away from us”, says Ray Beckerman (right) on Recording Industry vs The People , going on: “I sincerely hope that the media who have money for such things protest.” I wouldn’t hold your breath, Ray. In Viacom v YouTube , the  two are “making partial summary judgment motions on the applicability of the DMCA to YouTube”, he says.

It did as it was told but “that apparently wasn’t enough for Viacom and now it’s suing Google and YouTube for $1 billion, ‘over unauthorized use of its copyrighted entertainment,’ said The New York Times . The suit accused Google and its YouTube of  “massive intentional copyright infringement” of Viacom’s “entertainment assets” and sought an injunction against “further violations.” Three years on, they’re still at each other’s throats, hacking and parrying, and this time their documents have been filed under seal. “Whatever happened to ‘courts of record’?” – Beckerman asks, adding: “There is too much of this going on, and it always seems to be in RIAA/MPAA cases.
