  • Cisco Exec: Turnover In Engineering No Problem

    alphadogg (971356) writes The engineering reorganization currently underway at network giant Cisco Systems is intended to streamline product development and delivery to customers. That it is prompting some high profile departures is an expected byproduct of any realignment of this size, which affects 25,000 employees, says Cisco Executive Vice President Pankaj Patel, who is conducting the transformation. "People leave for personal business reasons," Patel said in an interview with Network World this week. "Similar transformations" among Cisco peers and customers "see personnel change of 30% to 50%."

  • Python-LMDB In a High-Performance Environment

    lkcl writes: In an open letter to the core developers behind OpenLDAP (Howard Chu) and Python-LMDB (David Wilson) is a story of a successful creation of a high-performance task scheduling engine written (perplexingly) in Python. With only partial optimization allowing tasks to be executed in parallel at a phenomenal rate of 240,000 per second, the choice to use Python-LMDB for the per-task database store based on its benchmarks, as well as its well-researched design criteria, turned out to be the right decision. Part of the success was also due to earlier architectural advice gratefully received here on Slashdot. What is puzzling, though, is that LMDB on Wikipedia is being constantly deleted, despite its "notability" by way of being used in a seriously-long list of prominent software libre projects, which has been, in part, motivated by the Oracle-driven BerkeleyDB license change. It would appear that the original complaint about notability came from an Oracle employee as well.

  • Mixing Agile With Waterfall For Code Quality

    jones_supa writes: The 2014 CAST Research on Application Software Health (CRASH) report states that enterprise software built using a mixture of agile and waterfall methods will result in more robust and secure applications than those built using either agile or waterfall methods alone. Data from CAST's Appmarq benchmarking repository was analyzed to discover global trends in the structural quality of business application software. The report explores the impact of factors such as development method, CMMI maturity level, outsourcing, and other practices on software quality characteristics that are based upon good architectural and coding practices. InfoQ interviewed Bill Curtis, Senior Vice President and Chief Scientist at CAST, about the research done by CAST, structural quality factors, and mixing agile and waterfall methods.

  • For Game Developers, It's About the Labor of Love

    Nerval's Lobster writes With "GamerGate" and all the debates over who counts as a "gamer," it's easy to forget that games are created by people with a genuine love of the craft. Journalist Jon Brodkin sat down with Armin Ibrisagic, game designer & PR manager for Coffee Stain Studios, the Swedish studio that made Goat Simulator, to talk about why they built that game and how it turned into such a success. Brodkin also talked to Leszek Lisowski, founder of Wastelands Interactive, about the same topic. While these developers might debate with themselves (and others) over whether to develop games for hardcore gamers, or jump on the mobile "casual gaming" bandwagon, they'll ultimately in it because they love games — a small but crucial detail that seems too easy to forget these days.

  • Adobe: Click-to-Play Would Have Avoided Flood of Java Zero-days

    mask.of.sanity writes: Oracle could have saved mountains of cash and bad press if Click-to-Play was enabled before Java was hosed by an armada of zero day vulnerabilities, Adobe security boss Brad Arkin says. The simple fix introduced into browsers over the last year stopped the then zero day blitzkrieg in its tracks by forcing users to click a button to enable Java.

  • Microsoft's JavaScript Engine Gets Two-Tiered Compilation

    jones_supa writes: The Internet Explorer team at Microsoft recently detailed changes to the JavaScript engine coming in Windows 10. A significant change is the addition of a new tier in the Just-in-Time (JIT) compiler. In Windows 10, the Chakra JS engine now includes a second JIT compiler that bridges the gap between slow, interpreted code and fast, optimized code. It uses this middle-tier compiler, called Simple JIT, as a "good enough" layer that can move execution away from the interpreter quicker than the Full JIT can. Microsoft claims that the changes will allow certain workloads to "run up to 30% faster". The move to a two-tiered JIT compiler structure mirrors what other browsers have done. SpiderMonkey, the JavaScript engine in Firefox, has an interpreter and two compilers: Baseline and IonMonkey. In Google Chrome, the V8 JavaScript engine is also a two-tiered system. It does not use an interpreter, but compiles on a discrete background thread.

  • Microsoft, Facebook Declare European Kids Clueless About Coding, Too

    theodp writes: Having declared U.S. kids clueless about coding, Facebook and Microsoft are now turning their attention to Europe's young 'uns. "As stewards of Europe's future generations," begins the Open Letter to the European Union Ministers for Education signed by Facebook and Microsoft, "you will be all too aware that as early as the age of 7, children reach a critical juncture, when they are learning the core life skills of reading, writing and basic maths. However, to flourish in tomorrow's digital economy and society, they should also be learning to code. And many, sadly, are not." Released at the launch of the European Coding Initiative — aka All You Need is Code! (video) — in conjunction with the EU's Code Week, the letter closes, "As experts in our field, we owe it to Europe's youth to help equip them with the skills they will need to succeed — regardless of where life takes them."

  • Oracle Database Certifications Are No Longer Permanent

    jfruh writes: It used to be that you could get an Oracle database certification and declare yourself Oracle-certified for the rest of your career. That time is now over, causing a certain amount of consternation among DBAs. On the one hand, it makes sense that someone who's only been certified on a decade-old version of the product should need to prove they've updated their skills. On the other, Oracle charges for certification and will definitely profit from this shift."

  • The Subtle Developer Exodus From the Mac App Store

    An anonymous reader writes: Milen Dzhumerov, a software developer for OS X and iOS, has posted a concise breakdown of the problems with the Mac App Store. He says the lack of support for trial software and upgrades drives developers away by preventing them from making a living. Forced sandboxing kills many applications before they get started, and the review system isn't helpful to anyone. Dzhumerov says all of these factors, and Apple's unwillingness to address them, are leading to the slow but steady erosion of quality software in the Mac App Store.

    "The relationship between consumers and developers is symbiotic, one cannot exist without the other. If the Mac App Store is a hostile environment for developers, we are going to end up in a situation where, either software will not be supported anymore or even worse, won't be made at all. And the result is the same the other way around – if there are no consumers, businesses would go bankrupt and no software will be made. The Mac App Store can be work in ways that's beneficial to both developers and consumers alike, it doesn't have to be one or the other. If the MAS is harmful to either developers or consumers, in the long term, it will be inevitably harmful to both."

  • Fighting the Culture of 'Worse Is Better'

    An anonymous reader writes: Developer Paul Chiusano thinks much of programming culture has been infected by a "worse is better" mindset, where trade-offs to preserve compatibility and interoperability cripple the functionality of vital languages and architectures. He says, "[W]e do not merely calculate in earnest to what extent tradeoffs are necessary or desirable, keeping in mind our goals and values -- there is a culture around making such compromises that actively discourages people from even considering more radical, principled approaches." Chiusano takes C++ as an example, explaining how Stroustrup's insistence that it retain full compatibility with C has led to decades of problems and hacks.

    He says this isn't necessarily the wrong approach, but the culture of software development prevents us from having a reasoned discussion about it. "Developing software is a form of investment management. When a company or an individual develops a new feature, inserts a hack, hires too quickly without sufficient onboarding or training, or works on better infrastructure for software development (including new languages, tools, and the like), these are investments or the taking on of debt. ... The outcome of everyone solving their own narrow short-term problems and never really revisiting the solutions is the sea of accidental complexity we now operate in, and which we all recognize is a problem."

  • Despite Push From Tech Giants, AP CS Exam Counts Don't Budge Much In Most States

    theodp (442580) writes "Well, the College Board has posted the 2014 AP Computer Science Test scores. So, before the press rushes out another set of Not-One-Girl-In-Wyoming-Took-an-AP-CS-Exam stories, let's point out that no Wyoming students of either gender took an AP CS exam again in 2014 (.xlsx). At the overall level, the final numbers have changed somewhat (back-of-the-Excel-envelope calculations, no warranty expressed or implied!), but tell pretty much the same story as the preliminary figures — the number of overall AP CS test takers increased, while pass rates decreased despite efforts to cherry pick students with a high likelihood of success. What is kind of surprising is how little the test numbers budged for most states — only 8 states managed to add more than 100 girls to the AP CS test taker rolls — despite the PR push by the tech giants, including Microsoft, Google, and, Facebook. Also worth noting are some big percentage decreases at the top end of the score segments (5 and 4), and still-way-too-wide gaps that exist between the score distributions of the College Board's various ethnic segments (more back of the envelope calcs). If there's a Data Scientist in the house, AP CS exam figures grabbed from the College Board's Excel 2013 and 2014 worksheets can be found here (Google Sheets) together with the (unwalkedthrough) VBA code that was used to collect it. Post your insight (and code/data fixes) in the comments!"

  • How Poor Punctuation Can Break Windows

    An anonymous reader writes with a report at Ars Technica about how a small bug can lead to a security problem. In this case, the problem is that quotation marks — or the lack of them — can be significant. From the Ars article: "The scenario... requires a 'standard' user with access rights to create a directory to a fileserver and an administrator executing a vulnerable script," Frank Lycops and Raf Cox, security researchers with The Security Factory, said in an e-mail interview. "This allows the attacker to gain the privileges of the user running the script, thus becoming an administrator." While the attack falls short of the severity of the Shellshock family of Linux shell vulnerabilities, the two researchers stressed that it's a good example of how untrusted input can be used to execute commands on a system. The researchers identified at least one popular script with the vulnerability. When the script attempts to set the starting directory for system administration work, it inadvertently runs the command appended to the malicious directory's name as well. ... The solution is to use proper coding practices—in this case, the judicious use of quotation marks. Quotation marks are used in the shell environment to make sure that the data inside the quotes is not interpreted by the program as a command.

  • Flash IDE Can Now Reach Non-Flash Targets (Including Open Source)

    lars_doucet (2853771) writes Flash CC now has an SDK for creating custom project file formats; this lets you use the Flash IDE to prepare and publish content for (not-the-flash-player) compile targets. Among these new platforms is OpenFL, a fully open-source re-implementation of the Flash API that exports to Javascript and C++ (no Flash Player!), among other targets: When Adobe demoed the custom project feature at Adobe MAX the other night, they brought out Joshua Granick (lead maintainer of OpenFL) to show off a custom OpenFL project format that lets you make Flash Art in Flash CC, then compile it out to Flash, HTML5, and native C++ (desktop+mobile) targets. Maybe Adobe heard us after all?

  • Where Intel Processors Fail At Math (Again)

    rastos1 writes: In a recent blog, software developer Bruce Dawson pointed out some issues with the way the FSIN instruction is described in the "Intel® 64 and IA-32 Architectures Software Developer's Manual," noting that the result of FSIN can be very inaccurate in some cases, if compared to the exact mathematical value of the sine function.

    Dawson says, "I was shocked when I discovered this. Both the fsin instruction and Intel's documentation are hugely inaccurate, and the inaccurate documentation has led to poor decisions being made. ... Intel has known for years that these instructions are not as accurate as promised. They are now making updates to their documentation. Updating the instruction is not a realistic option."

    Intel processors have had a problem with math in the past, too.

  • CSS Proposed 20 Years Ago Today

    An anonymous reader writes: On 10 October 1994, Opera CTO Hakon Lie posted a proposal for Cascading HTML style sheets. Now, two decades on, CSS has become one of the modern web's most important building blocks. The Opera dev blog just posted an interview with Lie about how CSS came to be, and what he thinks of it now. He says that if these standards were not made, "the web would have become a giant fax machine where pictures of text would be passed along." He also talks about competing proposals around the same time period, and mentions his biggest mistake: not producing a test suite along with the CSS1 spec. He thinks this would have gotten the early browsers to support it more quickly and more accurately. Lie also thinks CSS has a strong future: "New ideas will come along, but they will extend CSS rather than replace it. I believe that the CSS code we write today will be readable by computers 500 years from now."

  • BitHammer, the BitTorrent Banhammer

    michaelcole writes: Its name is BitHammer. It searches out and bans BitTorrent users on your local sub-net.

    I'm a digital nomad. That means I travel and work, often using shared Wi-Fi. Over the last year, I've been plagued by rogue BitTorrent users who've crept onto these public hostpots either with a stolen/cracked password, or who lie right to my face (and the Wi-Fi owners) about it.

    These users clog up the residential routers' connection tables, and make it impossible to use tools like SSH, or sometimes even web browsing. Stuck for a day, bullied from the Wi-Fi, I wrote BitHammer as a research project. It worked rather well. It's my first Python program. I hope you find it useful.

  • Goodbye, World? 5 Languages That Might Not Be Long For This World

    Nerval's Lobster writes As developers embrace new programming languages, older languages can go one of two ways: stay in use, despite fading popularity, or die out completely. So which programming languages are slated for history's dustbin of dead tech? Perl is an excellent candidate, especially considering how work on Perl6, framed as a complete revamp of the language, began work in 2000 and is still inching along in development. Ruby, Visual Basic.NET, and Object Pascal also top this list, despite their onetime popularity. Whether the result of development snafus or the industry simply veering in a direction that makes a particular language increasingly obsolete, time comes for all platforms at one point or another. Which programming languages do you think will do the way of the dinosaurs in coming years? With COBOL still around, it's hard to take too seriously the claim that Perl or Ruby is about to die. A prediction market for this kind of thing might yield a far different list.

  • Google Takes the Fight With Oracle To the Supreme Court

    whoever57 writes Google has asked the Supreme Court to review the issue of whether APIs can be copyrighted. Google beat Oracle in the trial court, where a judge with a software background ruled that APIs could not be copyrighted. but the Appeals court sided with Oracle, ruling that APIs can be copyrighted. Now Google is asking the Supreme Court to overturn that decision. (Also of interest.)
