prostoalex writes to tell us The Daily Mail has an interesting look at current research in the field of running and injuries related to running. Most of the evidence pointed at a lack of any need for running shoes. Some of the more interesting points: the more expensive the running shoes, the greater the probability of getting an injury; some of the planet's best and most intense runners run barefoot; Stanford running team, having access to the top-notch modern shoes sent in for free by manufacturers, after a few rounds of trial and error still chose to train with no shoes at all."

prostoalex writes "At QCon San Francisco, Aditya Agarwal of Facebook described how his employer runs its software stack (video and slides). Facebook runs a typical LAMP setup where P stands for PHP with certain customizations, and back-end services that are written in C++ and Java. Facebook has released some of the infrastructure components into the open source community, including the Thrift RPC framework and Scribe distributed logging server."

prostoalex writes "Most companies would call themselves innovative and would claim they're delivering an above-average service to their customers. Yet, their customers opinions might differ. If you drill a company on their innovation practices, they would probably mention two approaches they employ: 1. Their research department meets with target groups, compiles presentations for the upper management, which then occasionally hands those reports over to the development department. 2. Their research or marketing department comes up with competitive matrix of the products available from competition. In a meeting then, executives see that their product is missing a feature, and hence the development department is assigned the task of adding 'an Internet-enabled installer' to the product, since everybody else offers them, thereby creating market expectations." Read on for the rest of Alex's review. Subject to change author Peter Merholz, Todd Wilkens, Brandon Schauer, David Verba pages 186 publisher O'Reilly rating 7 reviewer Alex Moskalyuk ISBN 9780596516833 summary Creating great products and services for an uncertain world Subject to Change is a book, written by four Adaptive Path veterans describing new approaches to product development and innovation. Who are they to have the authority over the subject? Adaptive Path is a consulting shop helping large and small companies with product design, Web design and industrial design. They're perhaps mostly known to the general public for coining the term AJAX, and articulating the idea of building dynamic Web sites with asynchronous data retrieval, but they certainly didn't invent the technology. Their design experience is behind many products we use today, but due to licensing agreements they're not always at liberty to disclose their customers.

So what do Adaptive Path designers advocate?

Making the design emotional. While the idea itself is not new, this is something that product manufacturers have to face sooner or later. Early Kodak cameras did not succeed because of superior technical qualities or ease of film development — they managed to cross this emotional barrier, where people who previously thought "This is too complicated" after getting a glimpse of the ad or product demo thought "Even I might be able to enjoy this."

Understand people's needs outside of your company-approved usability testing guides. Two great examples provided by the book are Adaptive Path's own usability study of Epinions.com — product review and comparison shopping site. When a woman showed up for usability test with her newborn baby, she was frequently distracted by baby's needs during the test. Bad test candidate? Vice versa. Adaptive Path learned how confusing it could be for someone who needs to get away from the comparison shopping process to come back and quickly realize where they were in the process. Another example has to deal with babies as well — after watching new mothers use the diaper wipes at their homes, Kimberly-Clark researchers redesigned their diaper wipe container to be easily accessible with just one hand.

Make the whole system coherent, not just patch new interfaces throughout product holes. Financial companies and banks certainly suffer from a desire by single group to innovate the others out. My own example — I go to Fidelity Web site, and upon login offered to also check my NetBenefits(SM) or check out the FullView(R). Now, there might be customers who think in those terms, but I surely did not log in to check NetBenefits(SM) or do FullView(R) or check out mySmart Cash Account (SM), I just wanted to find out how my investments were doing. A simple graph would do. Yet my options from Fidelity are either downloading quarterly PDF account statements, and then punching the numbers to create a graph, or going to Account Positions page, where I can view the graphs for every single stock and bond I own for any time value except the time span that I need — from the day I bought the security to today. This is not a rant on Fidelity Investments in general, this is just another example of different groups within the company handling such things as stocks, bonds, retirement planning, cash investments, quarterly account reports, and Web site design. Each group probably doesn't think highly of the existing user interface, and hence the desire to introduce that new simple interface, call it a different name, and expect the customers to get on with a program and use it.

The authors provide a lot of good case studies for design successes and failures to support their point. Case studies are borrowed from outside literature or told in first person — Adaptive Path's customer names are changed to be KeyboardCo or FinanceCo to protect the innocent. The book explores several different permutations of design and relevance:

When design is great, and product is relevant, market success is a given. The example is Apple iPod series. Somewhat less known example is Google Calendar, that outgrew Yahoo! Calendar and MSN Calendar, even though all 3 calendars are tied into Web-based e-mails, and Yahoo! and Hotmail both have market shares multiple of Gmail's.

When design is great, but product is not relevant, market success will be extremely hard to achieve. Segway scooter and Apple G4 Cube come to mind.

When design is bad, but product is relevant, market success will quickly turn into failure as competitors copy the product and invest in design. Diamond Rio, the pioneer of digital music player industry, learned a hard lesson that way.

When design is bad, and the product is irrelevant, it's possible it will never even come out in the market. Adaptive Path's own example of KeyboardCo wanting to implement a downloadable music service right on the keyboard is a good example of this.

Overall the book is informative and inspirational, albeit a bit dry. Chapter 7, dedicated to describing agile approach in software development, seems to be out of place. Maybe it's because I am a software engineer, and have familiarized myself on various development methodologies, the chapter was old news to me, or maybe it's the idea that you're being sold one specific methodology, instead of implementing dozens of small improvements within the product development process, that threw me off.

On page 162 the authors claim "Google and Yahoo!, once technology companies, are now media players, and their advertising-based business models mean they compete more with Los Angeles and New York than their Silicon Valley brethren." Now, I don't see how being a media company leads one to compete with a US municipality. Maybe they meant "New York [Times|Post] and Los Angeles [Times]", in which case it's time to look for another proofreader. But to be fair, I haven't noticed any glaring errors or omissions in the title.

Subject to Change is a good book to read if you're into product development or design. If you're staying abreast of the industry trends, most of it is probably not going to be big news to you, nevertheless, it's a good collection of case studies and a summary of rules relevant for modern-day product development.

prostoalex writes "New York Times magazine explores the history and status quo of Internet trolling. They look at the early days of Usenet trolling, current anonymous forums, and social networking pages as the latest venues for trolls: 'In the late 1980s, Internet users adopted the word troll to denote someone who intentionally disrupts online communities. Early trolling was relatively innocuous, taking place inside of small, single-topic Usenet groups. The trolls employed what the M.I.T. professor Judith Donath calls a pseudo-naïve tactic, asking stupid questions and seeing who would rise to the bait. The game was to find out who would see through this stereotypical newbie behavior, and who would fall for it. As one guide to trolldom puts it, If you don't fall for the joke, you get to be in on it.'"

prostoalex writes "The bionic arm project sponsored by DARPA is nearing completion, and might undergo clinical trials. 'The arm has motor control fine enough for test subjects to pluck chocolate-covered coffee beans one by one, pick up a power drill, unlock a door, and shake a hand. Six preconfigured grip settings make this possible, with names like chuck grip, key grip, and power grip. The different grips are shortcuts for the main operations humans perform daily.'"

prostoalex writes "The Annals of Improbable Research, a scientific publication that hosts the annual Ig Nobel awards, has decided to offer its publication free online, News.com reports. According to the journal Web site, visitors can view HTML articles with low-res images or download low-res PDFs for free. High-resolution PDFs and 'traditional on-the-toilet-readable paper-and-ink' issues are still available for a subscription fee."

prostoalex writes "Each December the Bureau of Labor Statistics prepares a report on telecommunications spending among US households. They analyze the previous year's data, so their most recent release says that in 2006 the average US household spent $542 on their landline, and $524 on their wireless bill. The way the curves are headed, 2007 is likely to become the first year when wireless spending will surpass landline spending. 'To be sure, when corporate cell-phone use is counted, overall U.S. spending surpassed land line spending several years ago, analysts said.'"

prostoalex writes "Georgia Tech and University of Oxford scientists claim bees can help up develop a better Internet traffic algorithms. By observing bees, the researchers noticed that bees pass back information on route quality. 'On a basic level, the honeybee's dilemma is a tale of two flower patches. If one patch is yielding better nectar than the other, how can the hive use its workforce most efficiently to retrieve the best supply at the moment? The solution, which earned Austrian zoologist Karl von Frisch a Nobel Prize, is a communication system called the waggle dance.' Any practical applications of that? Well, apparently ad servers, serving banners across a variety of servers, can report back on the time it took to generate the page."

prostoalex writes "Marc Stevens, Arjen K. Lenstra, and Benne de Weger have released their paper 'Vulnerability of software integrity and code signing applications to chosen-prefix collisions for MD5'. It describes a reproducible attack on MD5 algorithms to fake software signatures. Researchers start off with two simplistic Windows applications — HelloWorld.exe and GoodbyeWorld.exe, and apply a known prefix attack that makes md5() signatures for both of the applications identical. Researchers point out: 'For abusing a chosen-prefix collision on a software integrity protection or a code signing scheme, the attacker should be able to manipulate the files before they are being hashed and/or signed. This may mean that the attacker needs insider access to the party operating the trusted software integrity protection or code signing process.'"

prostoalex writes "Several companies have announced solid state hard drives in excess of one terrabyte in size. ComputerWorld describes one from BitMicro that's just 3.5". Their flash drive will support up to 4 Gbps data transfer rate. From the article: 'SSDs access data in microseconds, instead of the millliseconds that traditional hard drives use to retrieve data. The BitMicro E-Disk Altima 4Gb FC delivers more than 55,000 I/O operations per second (IOPS) and has a sustained data transfer rate over 230MB/sec. By comparison, a fast hard drive for example will run at around 300 IOPS.'" Ah, the speed of tech. Seems like only last month we were talking about 500GB drives.

prostoalex writes "MSNBC has a special report on discovering online cheats at AbsolutePoker.com. A Costa Rican company belonging to a Canadian tribe at first denied all the accusations of any cheating going on, but after Serge Ravitch made a scrupulous analysis of the games' events, the reputation of AbsolutePoker.com was at stake. A detailed log file provided investigators with necessary details: an employee and partial owner of the site was one of the players involved, and having direct access to other players' cards allowed him to improve his game substantially."

prostoalex writes "IEEE Spectrum looks at current trends in artificial technology to crack the ancient Chinese game of Go, which theoretically has 10^60 potential endings. Is conquering the game via exhaustive search of all possibilities possible? 'My gut feeling is that with some optimization a machine that can search a trillion positions per second would be enough to play Go at the very highest level. It would then be cheaper to build the machine out of FPGAs (field-programmable gate arrays) instead of the much more expensive and highly unwieldy full-custom chips. That way, university students could easily take on the challenge.'"

prostoalex writes "Scientific American is reporting on scientific work done to map the euphoric religious feelings within the brain. As a result, it's now quite possible to experience 'proximity to God' via a special helmet: 'In a series of studies conducted over the past several decades, Persinger and his team have trained their device on the temporal lobes of hundreds of people. In doing so, the researchers induced in most of them the experience of a sensed presence — a feeling that someone (or a spirit) is in the room when no one, in fact, is — or of a profound state of cosmic bliss that reveals a universal truth. During the three-minute bursts of stimulation, the affected subjects translated this perception of the divine into their own cultural and religious language — terming it God, Buddha, a benevolent presence or the wonder of the universe.""

prostoalex writes "The annual Ig Noble awards by Annals of Improbable Research were announced tonight. The winners included the scientists who discovered that impotence drugs help with jet lag recovery, "a Dutch researcher who conducted a census of all the creepy-crawlies that share our beds, Spanish scientists who found that rats sometimes could not distinguish between Japanese spoken backwards and Dutch spoken backwards, an Australian woman who documented the indexing problems caused by the word "the", a Japanese researcher who extracted vanilla flavoring from cow dung, and a Taiwanese man who patented a Batman-like device that drops a net over bank robbers," MSNBC says."

prostoalex writes "Microsoft has launched a site dedicated to collaboration between Microsoft and open source community. The site helps developers, IT administrators, and IT buyers find out what Microsoft's product offerings are, and read articles about open source such as 'Open Source Provider Sees Sales Doubling After Moving Solutions to the Windows Platform.'" Relatedly, CNet has the news that the company has submitted its shared-sources license to the OSI for approval.

prostoalex writes "FastTCP technology, developed by researchers at CalTech, is being commercialized. A company called FastSoft has introduced a hardware appliance that delivers 15x-20x faster FTP transmissions than those delivered via regular TCP. Says eWeek: 'The algorithm implemented in the Aria appliance senses congestion by continuously measuring the round-trip time for the TCP acknowledgment and then monitoring how that measurement changes from moment to moment.'"

prostoalex writes "Dr. Dobb's Journal runs an article discussing the tools necessary for fuzzing (testing a system by generating random input in order to cause program failure or crash). Quoting: 'You are fuzzing a Web server's capability to handle malformed POST data and discover a potentially exploitable memory corruption condition when the 50th test case you sent that crashes the service. You restart the Web daemon and retransmit your last malicious payload, but nothing happens... The issue must rely on some combination of inputs. Perhaps an earlier packet put the Web server in a state that later allowed the 50th test to trigger the memory corruption. We can't tell without further analysis and we can't narrow the possibilities down without the capability of replaying the entire test set in a methodical fashion.'"

prostoalex writes "PC Magazine looks at 5 ideas that will reinvent computing. IMAX-quality movies at home with new projectors, a mid-air mouse that requires no flat surface, a home quantum computer, a router-based peer-to-peer system, and a man-made brain all made the list."

prostoalex writes "Researchers from Nanyang Technological University in Singapore have created a model teleportation system using quantum dots. PhysOrg reports that 'tiny clusters of atoms known as quantum dots may be excellent media for quantum teleportation, a physics phenomenon in which information — in the form of a quantum state, a very specific mathematical signature of an atom — can be transmitted almost instantaneously to a distant location without having to physically travel through space.'"

prostoalex writes "If you're launching a new blog into the blogosphere, does the common netiquette allow you to have a separate wiki to go with a blog? If the previous sentence irritated you, you're not alone. Folksonomy, blogosphere, blog, netiquette and blook are among the most hated Internet words, Lulu Blooker Prize research found."

prostoalex writes "As part of the deal with the FCC to approve the AT&T/BellSouth merger, AT&T started selling, but not advertising, a $10-per-month DSL service in 22 states, AP has learned. 'The service provides download speeds of up to 768 kilobits per second and upload speeds of up to 128 kbps, matching the speeds of the cheapest advertised AT&T plan, which costs $19.95 per month in the nine-state former BellSouth area and $14.99 in the 13 states covered by AT&T before the acquisition.'"

prostoalex writes "The Sacramento Bee tells the story of an El Dorado resident who had to go to small claims court to get his Gateway PC fixed: 'Right out of the box, he says, the computer displayed scattered graphics and wouldn't work properly. He says he called a Gateway salesman five times and sent him an e-mail to get an authorization number to send the computer back, but his phone calls and message were never returned. Then, over the course of months, Sheehan said he called Gateway technical support dozens of times.' Gateway insists that by clicking 'Accept' on a customer service EULA when the computer was first booted, Mr. Sheehan has waived his rights to sue the computer manufacturer in United States courts. The Gateway EULA states that conflicts must be resolved via private arbitrage. Sheehan, though, argues that he never saw the EULA, because of the broken graphics. As such, he's not held to that agreement." Some connections between this and a discussion about a Second Life case we had yesterday.

prostoalex writes "Facebook is now allowing third-party developers to create pages within the site. Developers can use a combination of the Facebook API and a subset of HTML to create interactive pages accessible from within Facebook. Users retain complete control over which applications they want to have installed, and which applications they want to see on other people's profile. Developers can build on top of Facebook's social grid, and in case of a popular application gain distribution through Facebook newsfeed."

prostoalex writes "Scientific American looks at a new approach to clearing networking jams, in research funded by the US military. Instead of using routers to route the packets from point A and point B, thus making some hop in the sequence critical for delivering the message, researchers are exploring a new approach called 'network coding.' (Here is the illustration cited in the article.)" Quoting: "[Four researchers] then at the University of Hong Kong published groundbreaking work that introduced a new approach to distributing information across shared networks. In... network coding, routers are replaced by coders, which transmit evidence about messages instead of sending the messages themselves. When receivers collect the evidence, they deduce the original information from the assembled clues. Although this method may sound counterintuitive, network coding, which is still under study, has the potential to dramatically speed up and improve the reliability of all manner of communications systems and may well spark the next revolution in the field. Investigators are, of course, also exploring additional avenues for improving efficiency; as far as we know, though, those other approaches generally extend existing methods.'"

prostoalex writes "An 'online media company' Zango, which gained notoriety for redirecting adult affiliate traffic and the first ever MySpace worm, is now suing the anti-spyware vendor PC Tools, maker of an application called 'Spyware Doctor', for removing Zango applications off the consumers' PCs. 'According to a posting on a blog called Spamnotes.com, Zango is seeking at least $35 million in damages, alleging that Spyware Doctor removes Zango's software without warning users that it will be deleted. The lawsuit was filed Tuesday in King County Superior Court in Seattle, according to Spamnotes.com. Formerly known as 180solutions, Zango is trying to clean up its tarnished reputation. In November it paid $3 million to settle U.S. Federal Trade Commission charges that its software was being installed deceptively on PCs.'"

prostoalex writes "The Guardian takes a look at the current developments in the world of holographic storage. Despite being available in research for over 40 years, the technology is getting commercialized only now, with InPhase Technologies launching its 600 GB write-once disk and a drive this fall. What avout the price? "The first holographic products are certainly not mass-market — a 600GB disc will cost around $180 (£90), and the drive costs about $18,000. Potential users include banks, libraries, government agencies and corporations.""

prostoalex writes "Your US driver's license has a magnetic stripe with unique ID in it, and your debit card carries a magnetic stripe with account information on it, so why not link the two together and allow people to use their driver's licenses as debit cards? That's precisely what a young company National Payment Card is doing in select locations, according to Business Week: 'Gas-station owners are pleased with the program too. Because NPC processes the payment as an e-check with the Automated Clearing House (ACH), a network most commonly used for direct deposits, participating retailers bypass credit card companies such as Visa and Mastercard.'"

prostoalex writes "Microsoft told Fortune magazine that various free software products violate at least 235 patents, and it's time to expect users of this software to pay up patent licensing royalties: 'Microsoft General Counsel Brad Smith and licensing chief Horacio Gutierrez sat down with Fortune recently to map out their strategy for getting FOSS users to pay royalties. Revealing the precise figure for the first time, they state that FOSS infringes on no fewer than 235 Microsoft patents.'"

prostoalex writes "At the annual shareholder meeting, Google put forth for voting a proposal for the company not to engage in self-censorship, resist by all legal means the demands to censor information, inform the user in case their information was provided to the government, and generally not to store sensitive user data in the countries with below average free speech policies. As this proposal, if passed, would effectively mean the end of Google's China operations, the shareholders rejected the document at the recommendation of the Board of Directors."

prostoalex writes "Yahoo has finally made a decision regarding Yahoo! Photos vs. Flickr battle, and will be shutting down Yahoo! Photos by the fall of this year. Even though Yahoo! Photos currently maintains a higher share of Internet visits, Flickr growth convinced the company to maintain a single photo site from now on. Says USA Today: 'Stewart Butterfield, who co-founded Flickr in 2004 with wife Caterina Fake, says the move is a "validation" of the central idea of Flickr: that photos in the digital age are very different from a physical print. "We saw it as a means of communication and connecting with people," says Butterfield, Flickr's general manager. "People can take a picture and get immediate feedback from all over the world, and you can't do that with a printed photo."'"

prostoalex writes "Dr. Dobb's Journal reviews 5 AJAX frameworks: Dojo 0.3.1, Prototype and Scriptaculous 1.4, Direct Web Reporting 1.0, Yahoo! User Interface Library 0.11.1 and Google Web Toolkit 1.0. Each framework was tested in two basic scenarios — writing a 'hub' (titled collapsible link list frequently seen on sidebars of many Web sites) and a 'tab panel' (horizontal tabbed navigation bar). During the process, Dr. Dobb's Journal reviewers noted that 'Dojo provides more features and HTML widgets than YUI and Prototype' but eventually 'settled on the Yahoo! User Interface Library.'"

prostoalex writes "Is music played via customized playlist delivered interactively (i.e., via user participation) or non-interactive (i.e., decisions are made on the server side)? The question does seem metaphysical, but it took Sony BMG Music Entertainment and Yahoo! six years to figure it out via a protracted legal battle. User-driven playlists are bucketed with on-demand music services, while server-driven playlists are equaled to broadcasts, thereby causing different licensing mechanisms to take place. Yahoo! inherited the legal wrangle when it purchased a music startup Launch, which built a music recommendation feature. The court decision determined that recommendation algorithms that rely on usage data to build playlists server-side are still eligible for broadcast license, thereby substantially lowering the costs of operating a music recommendation site."

prostoalex writes "The New York Times is running a story on a Silicon Valley company that is planning to revolutionize the movie business. It's no secret that the movie-going experience has been deteriorating, while the number of HDTVs sold has been rising steadily. A company called Vudu, run by a guy who started TiVo, is now building a box for peer-to-peer download of movies straight from the studios. That could enables the movie studios to make movies securely available to viewers on the day of release, and improves on the download experience offered by other shops, like Amazon Unbox, MovieLink and others: 'DVD sales began to stagnate because studios had finally plowed through their entire backlog of movies that could be released on the shiny discs. The success of iTunes was also proving that the digital transition was inevitable and that one powerful player, Apple, could control the market if Hollywood did not find other viable partners. And outlaw services like the pirate Web sites that use BitTorrent technology demonstrated that digital piracy, which had consumed the music business first, now posed a real problem for Hollywood.'"

prostoalex writes "Even if you spent only a single day in an economics class, you're probably familiar with a concept of supply and demand. The Associated Press is running an article on retailers employing mathematical models for price optimization, where some products are priced higher to generate higher margins, and some are discounted to generate larger volumes even at the expense of per-product margins. DemandTec, Oracle and SAP are some of the companies producing those mathematical models for retailers around the country, with AP listing some of the pricing optimizations employed currently."

prostoalex writes "Fed up with numerous violations of tax law by individuals and businesses selling goods on eBay, Amazon Marketplace, uBid.com, etc., IRS is pushing Congress to make online marketplaces responsible for reporting the sales information to the tax man, in order to prevent under-reporting of the income. eBay's 'own statistics suggest that there are 1.3 million people around the world who make their primary or secondary source of income through eBay, with just over 700,000 in the United States', News.com says." How long before the same fate befalls the folks who make a living working the Massively Multiplayer secondary markets?

prostoalex writes "A few days ago a Chinese company, Sohu.com, alleged Google improperly tapped its database for its Pinyin IME product, stirring controversy on whether two databases were similar just due to normal research process. Today Google admitted that its new product for Chinese market 'was built leveraging some non-Google database resources.' 'The dictionaries used with both software from Google and Sohu shared several common mistakes, where Chinese characters were matched with the wrong Pinyin equivalents. In addition, both dictionaries listed the names of engineers who had developed Sohu's Sogou Pinyin IME.'"

prostoalex writes "Washington state Governor signed a tax bill encouraging out of state businesses to collect sales taxes on purchases made by Washington state residents. It should be noted, though, that Washington state does not collect personal income tax, and hence relies on state sales tax for 53.1% of its revenues." As the article notes, "People who purchase items from out-of-state Internet or catalog companies are currently supposed to pay the sales tax, but rarely do." Looks like Washington-staters won't be able to fib on their tax returns about internet purchases, starting in 2008.

prostoalex writes "Music sales are not just falling, they're plummeting — by as much as 20% when you compare January-March 2007 with the 2006 numbers. The revenue numbers are actually worse, since CD prices are under pressure. The Wall Street Journal lists many factors contributing to the rapid decline: 800 fewer retail outlets (Tower Records' demise alone closed 89); increasingly negative attitude towards CD sales from big-box retailers (Best Buy now dedicates less floor space to CDs in favor of better-selling items); and file sharing, among others. Songs are being traded at a rate about 17 times the iTunes Store's recent rate of sales. Diminishing CD sales means that you don't have to sell as many to get on the charts. The 'Dreamgirls' movie soundtrack recently hit #1 by selling 60,000 CDs in a week, a number that wouldn't have made the top 30 in 2005."

prostoalex writes "Consumer Electronics Association and Computer Technology Industry Association introduced a new certification for individuals and companies installing home networks and connecting consumer electronics devices to a central PC: 'The certification is geared to individuals who install, integrate and maintain "smart" homes, in which the PC is the hub controlling lighting, security systems, audio-visual and digital entertainment gear, including home media centers.' The home networking market is predicted to grow at 20% a year globally."

prostoalex writes "2007 ACM International Collegiate Programming Contest is over with Warsaw University (Poland) winning it this year and solving all of the problems. The runner-up, Tsinghua University (China), finished with 7 problems solved, while St. Petersburg University of IT, Mechanics and Optics (Russia) and MIT (USA) are tied up for the third place with 6 problems solved. There were 6000 teams initially in the running, and in the final round of the competition only 88 remained."

prostoalex writes "Dr. Dobb's Journal runs a lengthy introduction to Linden Scripting Language, the language behind avatars and their interaction in Second Life: "LSL is a scripting language that runs server-side, on a piece of software called the simulator. The simulator does just what it's name implies — it simulates the virtual world of Second Life. Each simulator runs everything for 16 acres of virtual land — buildings, physics, and of course, scripts. While you manipulate the script text in a form that is somewhat easy to read, the actual code that runs on the simulator is compiled. A compiler is a piece of software that takes the text version of the script and converts it into something that can actually run. In the case of LSL, the compiler exists within the Second Life viewer itself. In the future, it is likely that the compiler will move from the viewer into the Second Life simulators, but where the code is compiled isn't very important. What matters is that the text is converted into a form that can run on the simulators.""

prostoalex writes "Google Apps is adding a premium offering: a custom 10-GB Gmail box, Google Calendar, GTalk instant messenger, Writely, Google Pages, Google Custom home page iGoogle and Google SpreadSheets for $50 a year per employee. The NYTimes provides some details on competitive pricing: 'By comparison, businesses pay on average about $225 a person annually for Office and Exchange,... in addition to the costs of in-house management, customer support and hardware, according to the market research firm Gartner.' Boston.com quotes an analyst for Nucleus Research on Google's ease-of-use: '"What we see in the Google Apps is a real focus on making them easy to use and intuitive," she said. "And that's something that Microsoft has been unable to do in all of its years with Office."' But the same analyst is bearish on Google Apps' shortcomings relative to the mature Microsoft desktop products: 'Right now Google's going to give companies a better ability to negotiate with Microsoft.'"

prostoalex writes "It's a big victory for Richard Stallman in North America, as Cuba decided to adopt open source software on the national level. Both Cuba and Venezuela are currently working on switching the entire government infrastructure to GNU/Linux operating system and applications, the Associated Press reports from Havana: 'Both governments say they are trying to wean state agencies from Microsoft's proprietary Windows to the open-source Linux operating system, which is developed by a global community of programmers who freely share their code.' The AP article doesn't mention the distro used for government workers, but says that the students are working on a Gentoo-based distro."

prostoalex writes "Canadian company D-Wave Systems is getting some technology press buzz after successfully demonstrating their quantum computer (discussed here earlier) that the company plans to rent out. Scientific American has a more technical description of how the quantum computer works, as well as possible areas of application: 'The quantum computer was given three problems to solve: searching for molecular structures that match a target molecule, creating a complicated seating plan, and filling in Sudoku puzzles.' Another attendee provides some videos from the demo." Anyone want to guess how long before "qubit" gets compressed to "quit" (as "bigit" became "bit" in the last century)?

prostoalex writes "Business Week magazine is looking at social networking sites opening their APIs to third-party developers to enable social applications not supported by the network itself. Facebook is setting an example by releasing their API from beta into 1.0, and many others are expected to follow the suit. Quoting from the article: 'Since Facebook, a network of 17 million college students, started a pilot program last summer, third-party developers have created some 100 new applications. Now a Facebook user name and password can be used to log in to content-sharing and chat site Mosoto, and to automatically import Facebook friends into Mosoto's buddy list for chat. Facebook itself does not offer a chat function.'"

prostoalex tips us to an article in MIT's Technology Review on a Stanford scientist's plan to replicate the processes inside the human brain with silicon. Quoting: "Kwabena Boahen, a neuroengineer at Stanford University, is planning the most ambitious neuromorphic project to date: creating a silicon model of the cortex. The first-generation design will be composed of a circuit board with 16 chips, each containing a 256-by-256 array of silicon neurons. Groups of neurons can be set to have different electrical properties, mimicking different types of cells in the cortex. Engineers can also program specific connections between the cells to model the architecture in different parts of the cortex."

prostoalex writes "Dr. Dobb's Journal reports on GPE Palmtop Environment's aim to create a full stack of open source software for mobile phones.
