Hangtime writes "The world's most valuable source code could be in the wild. According to a report by Reuters, a Russian immigrant and former Goldman Sachs developer named Sergey Aleynikov was picked up at Newark Airport on July 4th by the FBI on charges of industrial espionage. According to the complaint, Sergey, prior to his early June exit from Goldman, copied, encrypted and uploaded source code inferred to be the code used by Goldman Sachs to process in real-time (micro-seconds) trades between multiple equity and commodity platforms. While trying to cover his tracks, the system backed up a series of bash commands so he was unable to erase his history, which would later give him away to Goldman and the authorities. So the question is: where are the 32MB of encrypted files that Sergey uploaded to a German server?

In 1987, a study published by Jim Gray and Gianfranco Putzolu evaluated the trade-offs between holding data in memory and storing it on a disk. Known widely as the "five-minute rule," their research was updated and expanded 10 years later. Now, as jamie points out, Communications of the ACM is running an article by Goetz Graefe with another decennial update, evaluating the rule using hardware and software typical of 2007, with an eye toward how flash memory will affect the situation. An excerpt from Graefe's conclusion: "The 20-year-old five-minute rule for RAM and disks still holds, but for ever-larger disk pages. Moreover, it should be augmented by two new five-minute rules: one for small pages moving between RAM and flash memory and one for large pages moving between flash memory and traditional disks. For small pages moving between RAM and disk, Gray and Putzolu were amazingly accurate in predicting a five-hour break-even point two decades into the future. Research into flash memory and its place in system architectures is urgent and important. Within a few years, flash memory will be used to fill the gap between traditional RAM and traditional disk drives in many operating systems, file systems, and database systems."

jadoon88 writes to share a series of old Atari 7800 games that have been unofficially open sourced. "Remember Dig Dug or Centipede or Robotron? They used to be favorites when Atari's 7800 series was still around. Since the era of those consoles is over, and a different world of interactive reality gaming has taken over, Atari has unofficially released source code of over 15 games for the coders and enthusiasts to admire the state-of-the-art (because this is what it was back then). During those times, nobody would have imagined in their wildest dreams the games that Atari's developers floated into the gaming thirsty market and instantly swept across continental boundaries. But things changed soon after that and a company once regarded as one of the most successful gaming console manufacturers and developers faded away in the pages of our technology's hall-of-fame."

Jake Lazaroff writes "According to the W3 News Archive, the charter for the XHTML2 Working Group — set to expire on December 31st, 2009 — will not be renewed. What does this mean? XHTML2 will never be a W3C recommendation, so get on the HTML 5 bandwagon now. According to the XHTML FAQ, however, the W3C does 'plan for the XML serialization of HTML to remain compatible with XML.' Looks like with HTML 5, we'll get the best of both worlds."

blackbearnh writes with this excerpt from O'Reilly Radar "Think about Wikipedia, what some consider the most complete general survey of human knowledge we have at the moment. Now imagine squeezing it down to fit comfortably on an 8GB iPhone. Sound daunting? Well, that's just what Patrick Collison's Encyclopedia iPhone application does. App Store purchasers of Collison's open source application can browse and search the full text of Wikipedia when stuck in a plane, or trapped in the middle of nowhere (or, as defined by AT&T coverage...)"

sheepweevil writes "IBM just released Milepost GCC, 'the world's first open source machine learning compiler.' The compiler analyses the software and determines which code optimizations will be most effective during compilation using machine learning techniques. Experiments carried out with the compiler achieved an average 18% performance improvement. The compiler is expected to significantly reduce time-to-market of new software, because lengthy manual optimization can now be carried out by the compiler. A new code tuning website has been launched to coincide with the compiler release. The website features collaborative performance tuning and sharing of interesting optimization cases."

ericatcw writes "The inaugural NoSQL meet-up in San Francisco during last month's Yahoo! Apache Hadoop Summit had a whiff of revolution about it, like a latter-day techie version of the American Patriots planning the Boston Tea Party. Like the Patriots, who rebelled against Britain's heavy taxes, NoSQLers came to share how they had overthrown the tyranny of burdensome, expensive relational databases in favor of more efficient and cheaper ways of managing data, reports Computerworld."

Al writes "The AcceleGlove from AnthroTronix, is the first fully programmable glove that records hand and finger movements. Other gloves — like 5DT's Data Glove, which is used primarily in virtual reality — normally cost $1,000 to $5,000, but the AcceleGlove costs just $499. The AcceleGlove comes with software that lets developers use Java to program it for any application they wish. AnthroTronix initially developed the glove with the US Department of Defense for robotic control but it could also be used in video games, sports training, or physical rehabilitation."

todd10k writes "I've recently decided to go back to college. I have a lot of experience with games, having played them for most of my adult life, and have always toyed with the idea of making them one day. I've finally decided to give it my best. What I'd like to know is: what are the best languages to study? What are the minimum diploma or degree requirements that most games companies will accept? Finally, is C++ the way to go? ASP? LUA?"

Hugh Pickens writes "The Salt Lake City Tribune reports that the National Security Agency will be building a one million square foot data center at Utah's Camp Williams. The NSA's heavily automated computerized operations have for years been based at Fort Meade, Maryland, but the agency began looking to decentralize its efforts following the terrorist attacks of Sept. 11, 2001 and accelerated their search after the Baltimore Sun reported that the NSA — Baltimore Gas & Electric's biggest customer — had maxed out the local grid and could not bring online several supercomputers it needed to expand its operations. The agency got a taste of the potential for trouble January 24, 2000, when an information overload, rather than a power shortage, caused the NSA's first-ever network crash, taking the agency 3 1/2 days to resume operations. The new data center in Utah will require at least 65 megawatts of power — about the same amount used by every home in Salt Lake City — so a separate power substation will have to be built at Camp Williams to sustain that demand. 'They were looking at secure sites, where there could be a natural nexus between organizations and where space was available,' says Col. Scott Olson, the Utah National Guard's legislative liaison. NSA officials, who have a long-standing relationship with Utah based on the state Guard's unique linguist units, approached state officials about finding land in the state on which to build an additional data center. 'The stars just kind of came into alignment. We could provide them everything they need.'"

As IBM continues to build out Jazz, their community-oriented development site, technical lead Dr. Erich Gamma has offered to answer questions about Jazz or anything else in his realm of expertise. Among his many accomplishments, Erich worked with Kent Beck on the Java unit testing framework, JUnit, and was actively involved until JUnit 4. Dr. Gamma was also one of the fathers of Eclipse and the original lead on the Eclipse Java development tools. Feel free to fire away on Eclipse, Java, JUnit, the Rational suite, the Jazz site, or anything else you think Erich might be able to answer. Usual Slashdot interview rules apply. Update 19:05 GMT by SM: As pointed out by user Hop-Frog, Dr. Gamma is also co-author of the influential computer science textbook Design Patterns: Elements of Reusable Object-Oriented Software.

Some of the key new features include: namespaces, late static binding, closures, optional garbage collection for cyclic references, new extensions (like ext/phar, ext/intl and ext/fileinfo), over 140 bug fixes and much more."

snydeq writes "Fatal Exception's Neil McAllister questions whether the 'hacker ethic' synonymous with computer programing in American society is enough for developers to succeed in today's economy. To be sure, self-taught 'cowboy coders' — the hallmark of today's programming generation in America — are technically proficient, McAllister writes, 'but their code is less likely to be maintainable in the long term, and they're less likely to conform to organizational development processes and coding standards.' And though HTC's Vineet Nayar's proclamation that American programmers are 'unemployable' is overblown, there may be wisdom in offering a new kind of computer engineering degree targeted toward the student who is more interested in succeeding in industry than exploring computing theory. 'American software development managers often complain that Indian programmers are too literal-minded,' McAllister writes, but perhaps Americans have swung the pendulum too far in the other direction. In other words, are we 'too in love with the hacker ideal of the 1980s to produce programmers who are truly prepared for today's real-life business environment?'"

twitter writes "There's been a lot of fuss about mono lately. After SCO and MS suing over FAT patents, you would think avoiding anything MS would be a matter of common sense. RMS now steps into the fray to warn against a serious mistake: 'Debian's decision to include Mono in the default installation, for the sake of Tomboy which is an application written in C#, leads the community in a risky direction. It is dangerous to depend on C#, so we need to discourage its use. .... This is not to say that implementing C# is a bad thing. ... [writing and using applications in mono] is taking a gratuitous risk.'" Update: 06/27 20:22 GMT by T : Read on below for one Mono-eschewing attempt at getting the (excellent) Tomboy's functionality, via a similar program called Gnote. Update: 06/27 21:07 GMT by T: On the other side of the coin, reader im_thatoneguy writes "Jo Shields, a Mono Developer, has published an article on 'Why Mono Doesn't Suck,' why it is not a threat to FOSS, why it is desirable to developers and why it should be included in Ubuntu by default."

Midnight Thunder writes "I have spent the past six months working on a software project, and while I can come up with ideas, I just can't seem to sit down in front of the computer to code. I sit there and I just can't concentrate. I don't know whether this is akin to writer's block, but it feels like it. Have any other Slashdotters run into this and if so how did you get out of it? It is bothering me since the project has ground to a halt and I really want to get started again. I am the sole developer on the project, if that makes a difference."

Punk CPA writes "Technology Review has some thoughts about why the health care industry has been so slow to adopt IT, while quick to embrace high technology in care and diagnosis. Hypothesis: making medical records available for data analysis might expose redundancy, over-testing, and other methods of extracting profits from the fee-for-service model. My take is that it might also make it much easier to gather and evaluate quality of care information. That would be chum in the water for malpractice suits."

nerdyH writes "Intel's interesting 3D UI technology has arrived at a significant milestone. Emmanuele Bassi on Monday released Clutter 1.0rc1, commenting 'This is a development release of Clutter 0.9 leading towards the 1.0 stable cycle. It is the first release candidate for the 1.0.0 release.' Clutter is a centerpiece of Intel's Moblin stack for netbooks, MIDs, and IVIs. It aims beyond the traditional 2D 'desktop' UI metaphor, stepping up to a 'theatrical' metaphor in which 2D interface objects are likened to 'actors' moving around on a 3D 'stage,' with developers in the role of 'director.' Also updated Tuesday: the Clutter-GTK+ library, aimed at helping GTK+ developers Clutter up their existing apps."

Didier DURAND writes "Just published an article about our 100% automated migration from IBM mainframe with Cobol to Linux Java: we could convert of our own application (4 million lines of code) through the tools that we developed.

CWmike writes "Google has created a Web site for developers that is focused exclusively on making Web applications, sites and browsers faster. The site will allow developers to submit ideas, suggestions and questions via a discussion forum and by using Google's Moderator tool. Google hopes developers will join it in improving core online technologies such as HTML and TCP/IP. For Google, a prime example of how Web performance can be enhanced is the development of HTML 5, which provides a major improvement in how Web applications process Javascript, Google believes. 'We're hoping the community will spend some time on the basic protocols of the Internet,' Google product manager Richard Rabbat said. 'There's quite a bit of optimization that can be done [in that area].'"
