  • KDE Releases Frameworks 5

    KDE Community (3396057) writes The KDE Community is proud to announce the release of KDE Frameworks 5.0. Frameworks 5 is the next generation of KDE libraries, modularized and optimized for easy integration in Qt applications. The Frameworks offer a wide variety of commonly needed functionality in mature, peer reviewed and well tested libraries with friendly licensing terms. There are over 50 different Frameworks as part of this release providing solutions including hardware integration, file format support, additional widgets, plotting functions, spell checking and more. Many of the Frameworks are cross platform and have minimal or no extra dependencies making them easy to build and add to any Qt application. Version five of the desktop shell, Plasma, will be released soon, and packages of Plasma-next and KDE Frameworks 5 will trickle into Ubuntu Utopic over the next few days. There's a Live CD of Frameworks 5 / Plasma-next, last updated July 4th.

  • Oculus Suspends Oculus Rift Dev Kit Sales In China

    An anonymous reader writes with news about how Oculus is dealing with the reselling of dev kits in China. Bad news for those of you looking to get your hands on a preorder of the Oculus Rift virtual reality headset. A representative from Oculus recently confirmed that the company has had to stop selling its headsets in China as a result of an undisclosed amount of reselling. Which is to say, some of those preordering the developer edition of the virtual reality headset in China — not the consumer product, which hasn't been officially released in any capacity just yet — aren't actually looking to develop anything on the headsets. Nor are they even interested in getting a first look at the virtual reality capabilities of the $350 development kit. They're scalping, plain and simple, to take advantage of what appears to be a hefty amount of demand for the device.

  • IEEE Spectrum Ranks the Top Programming Languages

    An anonymous reader writes Working with computational journalist Nick Diakopoulos, we at IEEE Spectrum have published an app that ranks the popularity of dozens of programming languages. Because different fields have different interests (what's popular with programmers writing embedded code versus what's hot with web developers isn't going to be identical) we tried to make the ranking system as transparent as possible — you can use our presets or you can go in and create your own customized ranking by adjusting the individual weightings of the various data sources we mined.

  • Ask Slashdot: How Often Should You Change Jobs?

    An anonymous reader writes "We all know somebody who changes jobs like changing clothes. In software development and IT, it's getting increasingly hard to find people who have been at their job for more than a few years. That's partly because of tech companies' bias for a young work force, and partly because talented people can write their own ticket in this industry. Thus, I put the question to you: how often should you be switching jobs? Obviously, if you find the perfect company (full of good people, doing interesting things, paying you well), your best bet is to stay. But that's not the reality for most of the workforce. Should you always be keeping an eye out for new jobs? Is there a length of time you should stick around so you don't look like a serial job-hopper? Does there come a point in life when it's best to settle down and stick with a job long term?"

  • Does Google Have Too Much Influence Over K-12 CS Education?

    theodp writes:Google recently announced Global Impact Awards for Computer Science, part of the company's $50 million investment to get girls to code. But Google's influence over K-12 CS education doesn't stop there. The Sun-Times reports that Chicago Public School (CPS) teachers are participating in a summer professional development program hosted by Google as part of the district's efforts to "saturate" schools with CS within 3 years: "The launch of CS4All [Computer Science for All], in partnership with Code.org and supported by Google, starts this fall in 60 CPS schools to try to bridge the digital divide and prepare students." And in two weeks, the Computer Science Teachers Association [CSTA] and Google will be presenting the National Computer Science Principles Education Summit. "Attendees at this event have been selected through a rigorous application process that will result in more than 70 educators and administrators working together to strategize about getting this new Advanced Placement course implemented in schools across the country," explains CSTA. The ACM, NSF, Google, CSTA, Microsoft, and NCWIT worked together in the past "to provide a wide range of information and guidance that would inform and shape CS education efforts," according to the University of Chicago, which notes it's now conducting a follow-up NSF-funded study — Barriers and Supports to Implementing Computer Science — that's advised by CPS, CSTA, and Code.org.

  • Famo.us: Do We Really Need Another JavaScript Framework?

    An anonymous reader writes Front-end developer Jaroen Janssen has a post about Famo.us, "a custom built JavaScript 3D rendering and physics engine meant as a replacement for the standard layout engine of the browser." The engine effectively replaces a big chunk of HTML5 in order to render more efficiently by using technology based on WebGL. Janssen questions whether the world really needs another JavaScript framework: "Is it a bad thing that Famo.us replaces major parts of HTML5? To be honest, I'm not sure. As a Front-end developer I have to admit it makes me slightly uneasy to have to use a custom API instead of 'standard' HTML5. On the other hand, like almost everyone that makes web apps for a living, I have been terribly frustrated by some of HTML5 limitations, like slowness and browser incompatibilities. Either way, it might be a good thing to try a fundamentally different approach so I'm keeping an open mind for now.

    Famo.us chases another holy grail, namely the 'write once, run anywhere' dream. Instead of having to write different code for different platforms, like iOS and Android, developers can write one application that works and looks as good on all platforms, in theory anyway. This of course saves a huge amount of time and resources. Unfortunately, this idea is not without its problems and has never really worked very well with earlier attempts like Java-applets, Flash and Silverlight. In the end native applications have so far always been faster and slicker and I'm pretty skeptical Famo.us will be able to change this."

  • Damian Conway On Perl 6 and the Philosophy of Programming

    M-Saunders writes: Perl 6 has been in development since 2000. So why, 14 years later, hasn't it been released yet? Linux Voice caught up with Damian Conway, one of the architects of Perl 6, to find out what's happening. "Perl 6 has all of the same features [as Perl 5] but with the rough edges knocked off of them", he says. Conway also talks about the UK's Year of Code project, and how to get more people interested in programming.

  • Ask Slashdot: Switching From SAS To Python Or R For Data Analysis and Modeling?

    An anonymous reader writes "I work for a huge company. We use SAS all the time for everything, which is great if you have a bunch of non-programmer employees and you want them to do data analysis and build models... but it ends up stifling any real innovation, and I worry we will get left behind. Python and R both seem to be emerging stars in the data science game, so I would like to steer us towards one of them. What compelling arguments can you give that would help an old company change its standard if that company is pretty set in its ways?"

  • ARM Launches Juno Reference Platform For 64-bit Android Developers

    MojoKid writes One of the trickiest aspects to launching a new platform update is the chicken and egg problem. Without any hardware to test on, developers are leery of committing to supporting new hardware features. Without software that takes advantage of new hardware capabilities, customers aren't willing to pay for new equipment. This is the crux of the issue with respect to the ARMv8 architecture and enabling development for 64-bit Android platforms. As such ARM is readying their Juno development platform that combines several of ARM's most advanced technologies on a single board. The product supports big.Little in an asymmetric configuration; each board ships with two Cortex-A57s, four Cortex-A53s, and a modest Mali T-624 core. All this hardware needs an OS to run on — which is why ARM is announcing a 64-bit port of Android as part of this new development board. By including AOSP support as well as additional hooks and features from Linaro, ARM wants Juno to be a sort-of one-stop shopping product for anyone who needs to test, prototype, or design a 64-bit product for the ARM ecosystem. The Android flavor that's coming over is based on Linaro Stable Kernel 3.10. At launch, Juno will support OpenGL-ES 3.0, on-chip thermal and power management, up to 8GB of RAM (12.8GB/s of bandwidth), an optional FPGA, and USB 2.0. OpenCL 1.1 will be added in a future product update. The project is positioned as a joint ARM / Linaro launch with ARM handling the hardware and Linaro taking responsibility for the software stack.

  • Ask Slashdot: Choosing a Web Language That's Long-Lived, and Not Too Buzzy?

    adelayde (185757) writes "In my day job, I work on a web based service with a lot of legacy code written in that older (and some may say venerable) web-scripting language, Perl. Although we use Modern Perl extensions such as Moose, the language just seems to be ossifying and we're wanting to move to a more up-to-date and used language for web applications, or even an entire framework, to do new development. We're still planning to support the legacy code for a number of years to come; that's unavoidable. This is a fairly big project and it's mission critical to the business. The thing we're afraid of is jumping onto something that is too new and too buzzy as we'd like to make a technology decision that would be good at least for the next five years, if not more, and today's rising star could quite easily be in tomorrow's dustbin. What language and/or framework would you recommend we adopt?"

  • Happy Software Developers Solve Problems Better

    First time accepted submitter HagraBiscuit (2756527) writes Researchers from the Faculty of Computer Science, Free University of Bozen-Bolzano, Bolzano, Italy, have quantified and analysed affective mood index against objective measures of problem-solving effectiveness for a group of software developers. From the report abstract: "The results offer support for the claim that happy developers are indeed better problem solvers in terms of their analytical abilities. The following contributions are made by this study: (1) providing a better understanding of the impact of affective states on the creativity and analytical problem-solving capacities of developers, (2) introducing and validating psychological measurements, theories, and concepts of affective states, creativity, and analytical-problem-solving skills in empirical software engineering, and (3) raising the need for studying the human factors of software engineering by employing a multidisciplinary viewpoint.

  • Is K-12 CS Education the Next Common Core?

    theodp (442580) writes In an interview with The Washington Post's Lyndsey Layton that accompanied her report on How Bill Gates Pulled Off the Swift Common Core Revolution (the Gates Foundation doled out $233 million in grants to git-r-done), Gates denied that he has too much influence in K-12 education. Despite Gates' best efforts, however, there's been more and more pushback recently from both teachers and politicians on the standards, GeekWire's Taylor Soper reports, including a protest Friday by the Badass Teacher Association, who say Gates is ruining education. "We want to get corporations out of teaching," explained one protester. If that's the case, the "Badasses" probably won't be too pleased to see how the K-12 CS education revolution is shaping up, fueled by a deep-pocketed alliance of Gates, Google, Microsoft, Facebook, and others. Google alone has already committed $90 million to influence CS education. And well-connected Code.org, which has struck partnerships with school districts reaching over 2M U.S. students and is advising NSF-funded research related to the nation's CS 10K Project, will be conducting required professional development sessions for K-12 CS teachers out of Google, Microsoft, and Amazon offices this summer in Chicago, New York City, Boston, and Seattle. So, could K-12 CS Education ("Common Code"?) become the next Common Core?

  • Google Is Offering Free Coding Lessons To Women and Minorities

    redletterdave writes: According to a blog post from Gregg Pollack, CEO of the Code School, Google is paying for three free months for any women and minorities interested in tech to expand their skills. The offer is part of Google's $50 million "Made With Code" initiative, which aims to help close the gender gap in tech. While Google is also offering the same vouchers to the women in attendance at its annual I/O developers conference this week, the search giant has released an online application that's available to women everywhere. Google says its available vouchers for women number in the "thousands."

  • An Army Medal For Coding In Perl

    shocking writes: Arizona National Guard member Vivin Paliath was surprised to be commended for writing Perl scripts and Excel macros while his unit was deployed in Iraq. His work automated a number of previously manual processes that were part of the logistics processes of his unit. He wrote, '[A]s a programmer, I'm constantly looking for ways to make my job easy. I didn't want to sit and add qualifications, and print licenses one by one. I was too lazy for that, and worse, the whole thing was horribly inefficient. So I decided to figure out how to automate the process. ... I started writing Perl scripts to query the data. By the time we had reached Iraq, I had a working script that generated licenses as text files for all the soldiers. The script only took a second or two to run, and the longest part of the process was simply printing out the licenses. But I wasn't done yet. I was still annoyed that I would have to add driver qualifications manually. So I wrote another script that would go and add qualifications to drivers en masse. The script even had a configuration file where you could specify what qualifications you wanted to add and to whom."

  • Visualizing Algorithms

    An anonymous reader writes "Many people reading this site probably have a functional understanding of how algorithms work. But whether you know algorithms down to highly mathematical abstractions or simple as a fuzzy series of steps that transform input into output, it can be helpful to visualize what's going on under the hood. That's what Mike Bostock has done in a new article. He walks through algorithms for sampling, shuffling, and maze generation, using beautiful and fascinating visualizations to show how each algorithm works and how it differs from other options.

    He says, "I find watching algorithms endlessly fascinating, even mesmerizing. Particularly so when randomness is involved. ... Being able to see what your code is doing can boost productivity. Visualization does not supplant the need for tests, but tests are useful primarily for detecting failure and not explaining it. Visualization can also discover unexpected behavior in your implementation, even when the output looks correct. ...Even if you just want to learn for yourself, visualization can be a great way to gain deep understanding. Teaching is one of the most effective ways of learning, and implementing a visualization is like teaching yourself."

  • Building the Infinite Digital Universe of No Man's Sky

    An anonymous reader writes: Hello Games is a small development studio, only employing 10 people. But they're building a game, No Man's Sky, that's enormous — effectively infinite. Its universe is procedurally generated, from the star systems down to individual species of plant and animal life. The engine running the game is impressively optimized. A planet's characteristics are not computed ahead of time — terrain and lifeforms are randomly generated on the fly as a player explores it. But, of course, that created a problem for the developers — how do they know their procedural generation algorithms don't create ridiculous life forms or geological formations? They solved that by writing AI bot software that explores the universe and captures brief videos, which are then converted to GIF format and posted on a feed the developers can review. The article goes into a bit more detail on how the procedural generation works, and how such a small studio can build such a big game.

  • Why Software Builds Fail

    itwbennett writes: A group of researchers from Google, the Hong Kong University of Science and Technology and the University of Nebraska undertook a study of over 26 million builds by 18,000 Google engineers from November 2012 through July 2013 to better understand what causes software builds to fail and, by extension, to improve developer productivity. And, while Google isn't representative of every developer everywhere, there are a few findings that stand out: Build frequency and developer (in)experience don't affect failure rates, most build errors are dependency-related, and C++ generates more build errors than Java (but they're easier to fix).

  • Google I/O 2014 Begins [updated]

    Google I/O, the company's annual developer tracking^wdevelopers conference, has opened today in San Francisco. This year the company has reduced the number of conference sessions to 80, but also promised a broader approach than in previous years -- in other words, there may be a shift in focus a bit from Google's best known platforms (Chrome/Chrome OS and Android). Given its wide-ranging acquisitions and projects (like the recent purchase of Nest, which itself promptly bought Dropcam, the ever smarter fleet of self-driving cars, the growing number of Glass devices in the wild, and the announcement of a 3D scanning high end tablet quite unlike the Nexus line of tablets and phones), there's no shortage of edges to focus on. Judging from the booths set up in advance of the opening (like one with a sign announcing "The Physical Web," expect some of the stuff that gets lumped into "the Internet of Things." Watch this space -- updates will appear below -- for notes from the opening keynote, or follow along yourself with the live stream, and add your own commentary in the comments. In the days to come, watch for some video highlights of projects on display at I/O, too. Update: 06/25 17:41 GMT by T : Updates rolling in below on Android, wearables, Android in cars, Chromecast, smart watches, etc.Keep checking back! (Every few minutes, I get another chunk in there.)
