'Java 8 is trying to "innovate," according to the Microsoft meaning of the word. This means stealing a lot of things that have typically been handled by other frameworks and languages, then incorporating them into the language or runtime (aka standardization). Ahead of the next release, the Java community is talking about Project Lambda, streams, functional interfaces, and all sorts of other goodies. So let's dive into what's great — and what we can hate.'"

tlhIngan writes "Microsoft was the last platform manufacturer to require that all games go through publishers, a much hated policy. Indeed, their approval process was one of the harshest around. But now Microsoft will allow indie developers to self publish, and allow retail Xbox One units to serve as developer consoles. Previously, self-publishing developers were relegated to the 'Xbox Live Indie Arcade' section, as well as developer consoles often costing upwards of $10,000 with special requirements and NDAs. This puts Microsoft's Xbox One more in line with Apple's App Store, including Microsoft's new promise of a 14-day turnaround for approvals. Microsoft's retail debug console system is to work similarly to Apple's — that is, to run pre-release code, the individual consoles used have to be registered with Microsoft."

An anonymous reader writes "How can we ensure, together, that this will not be the last GUADEC? Last year, during GUADEC, there was that running joke amongst some participants that this was the last GUADEC. It was, of course, a joke. Everybody was expecting to see each other in Brno, in 2013. One year later, most of those who were joking are not coming to GUADEC. For them, the joke became a reality. People are increasingly leaving the desktop computer to use phones, tablets and services in the cloud. The switch is deeper and quicker than anything we imagined. Projects are also leaving GTK+ for QT. Unity abandoned GTK+, Linus Torvald's Subsurface is switching from GTK+ to Qt. If you spot a GNOME desktop in a conference, chances are that you are dealing with a Red Hat employee. That's it. According to Google Trends, interest in GNOME and GTK+ is soon to be extinct."
Travis Goodspeed has authored a blog post detailing his method of tracking low-earth-orbit satellites. Starting with an old Felcom 82B dish made for use on maritime vessels, he added motors to move it around and a webcam-based homemade calibration system. "For handling the radio input and controlling the motors, I have a BeagleBone wired into a USB hub. These are all mounted on the trunk of the assembly inside of the radome, sending data back to a server indoors. ... In order to operate the dish, I wanted both a flashy GUI and concise scripting, but scripting was the higher priority. Toward that end, I constructed the software as a series of daemons that communicate through a PostgreSQL database on a server inside the house. For example, I can run SELECT * FROM sats WHERE el>0 to select the names and positions of all currently tracked satellites that are above the horizon. To begin tracking the International Space Station if it is in view, I run UPDATE target SET name='ISS';. For predicting satellite locations, I wrote a quick daemon using PyEphem that fetches satellite catalog data from CelesTrak. These positions are held in a database, with duplicates filtered out and positions constantly updated. PyEphem is sophisticated enough to predict in any number of formats, so it's easy to track many of the brighter stars as well as planets and deep-space probes, such as Voyagers 1 and 2."
dcblogs writes "Software employment is rising at 4 to 5% a year, and may be the only tech occupation to have recovered to full employment since the recession. Other tech occupations aren't doing as well. In 2001, there were more than 200,000 people working in the semi-conductor industry. That number was less than 100,000 by 2010, according to a recent study by the Economic Policy Institute. Darin Wedel, who was laid off from Texas Instruments, and gained national attention when his wife, Jennifer, challenged President Obama on H-1B use, said that for electrical engineers, 'unless you are in the actual design of circuits, then you're not in demand.' He said that much of the job loss in the field is due to the closing of fabrication facilities. Wedel has since found new work as a quality engineer."
Karrde712 writes "Fedora Cloud Architect Matthew Miller announced a proposal on a plan to redesign the way that the Fedora Project builds its GNU/Linux distribution. Fedora has often been described as a 'bag of bits,' with thousands of packages and only minimal integration. Miller's proposal for 'Fedora.Next' describes reorganizing the packages and upstream projects that comprise Fedora into a series of 'rings,' each level of which would have its own set of release and packaging requirements. The lowest levels of the distribution may be renamed to 'Fedora Core.' Much discussion is ongoing on the Fedora Devel mailing list. If any Slashdot readers have good advice to add to the discussion, it would be most useful to respond to the ongoing thread there." A full presentation on the plan will be given at the Flock conference next month, and draft slides have been uploaded. A few more details about the discussion are below the fold.

dryriver writes "I am an intermediate-level programmer who works mostly in C# NET. I have a couple of image/video processing algorithms that are highly parallelizable — running them on a GPU instead of a CPU should result in a considerable speedup (anywhere from 10x times to perhaps 30x or 40x times speedup, depending on the quality of the implementation). Now here is my question: What, currently, is the most painless way to start playing with GPU programming? Do I have to learn CUDA/OpenCL — which seems a daunting task to me — or is there a simpler way? Perhaps a Visual Programming Language or 'VPL' that lets you connect boxes/nodes and access the GPU very simply? I should mention that I am on Windows, and that the GPU computing prototypes I want to build should be able to run on Windows. Surely there must a be a 'relatively painless' way out there, with which one can begin to learn how to harness the GPU?"
New submitter LFSim writes "It's not the Turing test just yet, but in one more domain, AI is becoming increasingly competitive with humans.

From the European Space Agency comes the news that researchers from its Advanced Concepts Team have recently won the Gold 'Humies' award for their use of Evolutionary Algorithms to design a spacecraft's trajectory for exploring the Galilean moons of Jupiter (Io, Europa, Ganymede and Callisto). The problem addressed in the awarded article (PDF) was put forward by NASA/JPL in the latest edition of the Global Trajectory Optimization Competition. The team from ESA was able to automatically evolve a solution that outperforms all the entries submitted to the competition by human experts from across the world. Interestingly, as noted in the presentation to the award's jury (PDF), the team conducted their work on top of open-source tools (PaGMO / PyGMO and PyKEP)."

Towards that end, Microsoft will award $100,000 worth of donations to five technology education nonprofits 'who teach programming and provide technical resources to those who might not otherwise get the chance.' So, how will Microsoft determine who's most worthy? With a popularity contest, of course! At the end of October, the top five vote-getting nonprofits — only Windows AzureDev Community members are eligible to vote — will split the Microsoft Money. By the way, currently in second place but trying harder is Code.org, the seemingly dual-missioned organization advised by Microsoft's Smith which has reached out to its 140,000 Facebook fans, and 17,000 Twitter followers in its quest for the $50,000 first prize."

Have an environment where it’s Linux underneath, boots into Scratch and hold down a key at a particular point during boot and it doesn’t boot into Scratch it just drops into the prompt. So you can play with Scratch for six months, once you’re happy with Scratch you turn over the page and 'Hold down F1 during boot,' and it’s like 'Oh look - it’s a PC!' So I think that’s something we’d really like to do."
An anonymous reader writes "I recently (within the past couple years) graduated from college with a bachelor's degree in Computer Science and currently work as a programmer for a large software consulting firm. However, I've become gradually disillusioned with the financial-obsession of the business world and would like to work for the overall betterment of humanity instead. With that in mind, I'm looking to shift my career more toward the scientific research side of things. My interest in computer science always stemmed more from a desire to use it toward a fascinating end — such as modeling or analyzing scientific data — than from a love of business or programming itself. My background is mostly Java, with some experience in C++ and a little C. I have worked extensively with software analyzing big data for clients. My sole research experience comes from developing data analysis software for a geologic research project for a group of grad students; I was a volunteer but have co-authorship on their paper, which is pending publication. Is it realistic to be looking for a position as a programmer at a research institution with my current skills and experiences? Do such jobs even exist for non-graduate students? I'm willing to go to grad school (probably for geology) if necessary. Grad school aside, what specific technologies should I learn in order to gain an edge? Although if I went back to school I'd focus on geology, I'm otherwise open to working as a programmer for any researchers in the natural sciences who will take me."
Nerval's Lobster writes "Developer and editor Jeff Cogswell is back with a comparison of Eclipse and Visual Studio, picking through some common complaints about both platforms and comparing their respective features. 'First, let's talk about usability,' he writes, 'and let's be frank: Neither Eclipse nor Visual Studio is a model for sound usability.' That being said, as an open-source project, Eclipse wins some points for its customizability and compatibility with languages; it's more difficult to modify Visual Studio to meet some programmer needs, which has led to any number of abandoned projects over the years. Microsoft choosing to eliminate macros in recent versions of Visual Studio has also led to some programmer frustrations (and a need for external tools)."
WebMink writes "After strong criticism last year, Github has finally accepted the view that public repositories with no open source license are a bad thing. Self-described as the 'world's largest open source community,' a significant number of GitHub projects come with no rights whatsoever for you to use their code in an open source project. But from now on, creators of new repositories will have to pick from a small selection of OSI-approved licenses or explicitly opt for 'no license'. In Github's words, 'please note that opting out of open source licenses doesn't mean you're opting out of copyright law.'" A quick scan of their new choose a license site reveals at least a few flaws: they present simplicity, caring about patents, and sharing improvements with others as mutually exclusive points when they clearly are not (e.g. the Apache license and the GPLv3 both help with patent concerns, but only Apache is mentioned; and the MIT/X license is listed as the simple license when BSD-style is more prevalent). They also imply it is entirely optional to actually note your copyright in your files, when it is really bad practice not to unless you really want to make it impossible for people to understand the copyright history when e.g. merging your code into another project. Their list of licenses does provide a nice overview of the features of each, but regrettably encourages the use of the GPLv2 (without the "or later version" clause), listing the GPLv3 and all versions of the LGPL in league with seldom used licenses like the Perl Artistic license.

I'm sitting in my home office wearing a bathrobe. The same way I'm not going to start wearing ties, I'm *also* not going to buy into the fake politeness, the lying, the office politics and backstabbing, the passive aggressiveness, and the buzzwords.

He also offered cookies in exchange for joining the dark side. An earlier reply by Linus further explains why he thinks it is OK to be mean: most of the time, he's only yelling at people who should know better (cultivating a crew of lead developers bound to him by Stockholm Syndrome?).

Except in Amman and other Middle Eastern cities, it seems. There, the share of women entrepreneurs is said to average 35% — an estimate seemingly confirmed by the mix of the sexes at 'Mix'n'Mentor,' a recent gathering in the Jordanian capital organised by Wamda, an online publication for start-ups. Reasons abound, and they are not always positive, says Nina Curley, Wamda's editor. Although more than half of university graduates in many Middle Eastern countries (51% in Jordan) are women, the workforce is dominated by men (women provide only 21% of it overall, and a paltry 16% in Jordan). The internet, however, is a new space that is more meritocratic and not as heavily male. The technology also lets entrepreneurs work from home, making it easier to raise children."

The result is that there is no entry in the database for the special plates when the automated photo radar system is triggered, this means nobody receives a citation. In one case a Colorado resident, who had vanity plates reading '33,' received the photo radar citations intended for Senator Mike Johnston representing district 33, whose vehicle was identified by a '33' on his special plate. Lt. Matt Murray of the Denver Police, speaking of the system commented, 'Our system works, the database works. What needs to happen is the state's database need to be complete.'"

When DB articles come up on Slashdot, I don't recognize a good deal of the terminology. What is the best way for a technical person to learn SQL/DB work using PostgreSQL? Books? Tutorials?

First time accepted submitter jasax writes "As an Amazon frequent buyer, I rely quite a lot on reviews of the books I want. However, some caution is in order: the (bad) quality of Amazon's reviews and reviewers under the Amazon Vine program has already been news in Slashdot. Today I was shocked by a practical result of that program. This second edition (published in 2012) of a very specialized system identification book has 12 reviews: the oldest (dated 2007) certainly targets the first edition. The remaining 11 reviews are all from 'Vine Reviewers' (VRs). All seem to be ignorant of what 'System Identification in the Frequency Domain' really is. None of the reviews is tagged with a 'Verified Amazon Purchase'; most (if not all) are 'small talk reviews' peppered with technical phrases cloning the publisher's book description, and some of the reviews are ridiculous, to say the least. If this sample of reviewing by VRs really is the norm, then the bottom line is that the Vine program is totally irrelevant and unreliable — at least for technical books."
grahamsaa writes "I work at medium sized company that offers a number of products that rely fairly heavily on backend databases, some of which are hundreds of gigabytes and deal with hundreds or thousands of queries per second. Currently, we're using a mix of Postgres, Oracle, and MySQL, though we're working hard to move everything to Postgres. The products that are still on MySQL and Oracle were acquisitions, so we didn't get to choose the RDBMS at the time these products were designed. So far, we've been very happy with Postgres, but I know next to nothing about Oracle. It's expensive and has a long history of use in large enterprises, but I'm curious about what it offers that Postgres might not — I'm not saying this because I think that sticking with Oracle would be a good idea (because in our case, it probably isn't), but I'm curious as to how some companies justify the cost — especially considering that EnterpriseDB makes transitioning from Oracle to Postgres feasible (though not painless) in most cases. For those that use Oracle — is it worth the money? What's keeping you from switching?"

The upshot is that builds are usually late, not properly tested and developers get the flak when things go wrong. I suspect the answer is political, but how do we make things better? One idea I had was that every time a new request comes in — no matter how small — the build gets pushed back by 24 or even 48 hours. I'd love to hear your ideas or success stories.

dcblogs writes "There are about 18.2 million software developers worldwide, a number that is due to rise to 26.4 million by 2019, a 45% increase, says Evans Data Corp. in its latest Global Developer Population and Demographic Study. Today, the U.S. leads the world in software developers, with about 3.6 million. India has about 2.75 million. But by 2018, India will have 5.2 million developers, a nearly 90% increase, versus 4.5 million in the U.S., a 25% increase though that period, Evans Data projects. India's software development growth rate is attributed, in part, to its population size, 1.2 billion, and relative youth, with about half the population under 25 years of age. Rapid economic growth is fueling interest in development. India's services firms hire, in many cases, thousands of new employees each quarter. Consequently, IT and software work is seen as clear path to the middle class for many of the nation's young. For instance, in one quarter this year, Tata Consultancy Services added more than 17,000 employees, gross, bringing its total headcount to 263,600. In the same quarter of 2010, the company had about 150,000 workers."

Compare that to the average annual cost of a single North American developer (about $100,000, plus 50% overhead), 'we see that the cost of either of these VRPs (vulnerability reward programs) is comparable to the cost of just one member of the browser security team,' the researchers wrote (PDF).

Nerval's Lobster writes "In the fall of 2014, 20 promising video game developers will begin a yearlong (and free) program at the University of Texas at Austin, where they will study under some of the gaming industry's most successful executives. 'The idea is to get the best of the best of the best, run them through a Navy Seals boot camp of sorts and not force them to worry about "how do I pay the rent and buy groceries,"' said program leader Warren Spector, who is responsible for creating well-known games such as Deus Ex. 'Fingers crossed, when we start delivering graduates who can contribute in major ways to the development of future games, that philanthropy will continue.' In a wide-ranging interview, Spector also talked about how his future students will be graduating into an industry in which 'every business model is broken, which is either terrifying or an opportunity depending on how you look at it.' Focus groups, analysis of historical trends, and aggregated game review scores may be comforting to number crunchers, but the majority of game projects still end up as commercial failures. Spector ultimately believes the people who actually make the games are going to make better decisions than the number crunchers. 'We've got to be looking forward and any time you start bringing data into it, you're not," Spector said. "I pitched a Lego construction game in 1989, and guess what: Minecraft is basically a Lego construction game. But at the time I was told "no, that won't work." I pitched a western game and the response was "westerns don't sell." And then Red Dead Redemption came out. Stuff doesn't sell until someone makes one that sells, and no amount of data can reveal what new thing is going to sell. The metrics and data guys, and the publishing guys will never come up with the next big thing.'""

So, it's a world that kind of resembles today's Silicon Valley, where the NY Times reports that the median age of workers is 29 years old at Google and 28 years old at Facebook. The report that technology workers are young — really young — comes on the heels of other presumably-unrelated stories that Silicon Valley execs can't find enough skilled workers and no one would fund Doug Engelbart in the last four decades of his life. On the bright side, at least old techies don't die in Silicon Valley — they just can't get hired."
An anonymous reader writes "Following up on an experiment from December, Michael Hansen has recorded video of programmers of varying skill levels as the read and evaluate short programs written in Python. An eye tracker checks 300 times per second to show what they look at as they mentally digest the script. You can see some interesting differences between experts and beginners: 'First, Eric's eye movements are precise and directed from the beginning. He quickly finds the first print statement and jumps back to comprehend the between function. The novice, on the other hand, spends time skimming the whole program first before tackling the first print. This is in line with expectations, of course, but it's cool to see it come out in the data. Another thing that stands out is the pronounced effect of learning in both videos. As Eric pointed out, it appears that he "compiled" the between function in his head, since his second encounter with it doesn't require a lengthy stop back at the definition. The novice received an inline version of the same program, where the functions were not present. Nevertheless, we can see a sharp transition in reading style around 1:30 when the pattern has been recognized.'"
WebMink writes "A discussion in the Debian community reveals that last month Oracle quietly disclosed a change for the embedded BerkeleyDB database from the quirky Sleepycat License to the Affero General Public License (AGPL) in future versions. AGPL is only compatible with GPLv3 and treats web deployment as a trigger to license compliance, so developers using BerkeleyDB will need to check their code is still legally licensed. Even if they had made the switch in the interests of advancing software freedom it would be questionable to force so many developers into a new license compatibility crisis. But it seems likely their only motivation is to scare more people into buying proprietary licenses. Oracle are well within their rights, but developers are likely to treat this as a betrayal. As a poster in the Debian thread says, "Oracle move just sent the Berkeley DB to oblivion" because there are some great alternatives, like OpenLDAP's LMDB."

Tech workers aren't organized in any significant way except through professional associations. They don't strike. But the tech industry is highly organized, and getting more so. Industry lobbying spending has been steadily rising, reaching $135 million last year, almost as much as the oil and gas industry. But in just one day of striking, BART workers have cost the local economy about $73 million in lost productivity due to delays in traffic and commuting. Software developers aren't likely to unionize. As with a lot of professionals, they view themselves as people with special skills, capable of individually bargaining for themselves, and believe they have enough power in the industry to get what they want, said Victor Devinatz, a professor of management and quantitative methods at Illinois State University College of Business. For unions to get off the ground with software workers, Devinatz said, 'They have to believe that collective action would be possible vehicle to get the kinds of things that they want and that they deserve.'"
itwbennett writes "Software developers are, by and large, a cool and analytical bunch, but there are a handful of things that strike terror in their hearts. Phil Johnson scoured developer forums looking for an answer to the question: What's your biggest fear as a programmer? The answers clustered into 5 broad groups ranging from being forced to learn or use a specific technology to working for and with incompetents. What's your biggest fear?"
CowboyRobot writes "ACM has an article about how Netflix conducts its resilience testing. Instead of the GameDays used by sites such as Amazon and Google, Netflix uses what they call The Simian Army, based on the philosophy that 'Resilience can be improved by increasing the frequency and variety of failure and evolving the system to deal better with each new-found failure, thereby increasing anti-fragility.' While GameDay exercises are like a fire-drill, with scheduled exercises where failure is manually introduced or simulated, the Simian Army relies on failure in the live environment induced by autonomous agents known as 'monkeys.' Chaos Monkey randomly terminates virtual instances in a production environment that are serving live customer traffic. Chaos Gorilla causes an entire Amazon Availability Zone to fail. And Chaos Kong will take down an entire region of zones. 'What doesn't kill you makes you stronger' and Netflix hopes that by constantly protecting itself from internal onslaught, they will become increasingly 'anti-fragile — growing stronger from each successive stressor, disturbance, and failure.'"
moon_unit2 writes "Tech Review has a story on research showing that facial recognition software can accurately spot signs that programming students are struggling. NC State researchers tracked students learning java and used an open source facial-expression recognition engine to identify emotions such as frustration or confusion. The technique could be especially useful for Massive Open Online Courses — where many thousands of students are working remotely — but it could also help teachers identify students who need help in an ordinary classroom, experts say. That is, as long as those students don't object to being watched constantly by a camera."
vikingpower writes "Clinkle, a new mobile payments start-up, may or may not have succeeded where so many other efforts have fizzled by inventing a practical way to replace credit cards with smartphones. It's hard to say, though, since Clinkle won't say much about how its system works. Its website is, well ... slight. But a prominent group of Silicon Valley investors who do know what Clinkle is cooking up are acting as though it has achieved a breakthrough. On Thursday, Clinkle announced that it had raised $25 million in early financing from Accel Partners; Andreessen Horowitz; Intel; Intuit; Marc Benioff, the chief executive of Salesforce.com; Peter Thiel, the co-founder of PayPal; and a long list of other investors with technology industry pedigrees. The Huffington Post has an article on Clinkle, or rather on Stanford students putting their degree on hold to go work at Clinkle. The Wall Street Journal [paywalled] mentions Clinkle having some 30-odd employees already."
theodp writes "Silicon Valley's stranglehold on West Coast innovation is in danger. The main problem? It's no fun to live in Silicon Valley. Technology is people, explains The Atlantic's Derek Thompson, and more people are choosing to live in cities. And Silicon Valley isn't like a city, it's like a suburb. 'What's happening now,' says author Bruce Katz, 'is workers want to be in Oakland and San Francisco.' So, how might Silicon Valley save itself? 'Silicon Valley is going to have to urbanize,' Katz said. '[There is a] migration out of Silicon Valley to places where people really want to live.'"
Proudrooster writes "As technologists, developers, and programmers it is essential to keep moving forward as technology advances so that we do not find ourselves pigeonholed, irrelevant, or worse, unemployed. If you had to choose a new technology skill to add to your personal inventory this summer, what would it be and why? Also, where would you look for the best online training (iTunesU, Lynda.com)? The technologies that immediately jump out as useful to me are HTML5, XCODE, and AJAX. How about you?"
