I would like to start with a NoSQL solution for scaling, and ideally it would be dead simple if possible. I've been looking at MongoDB, Couchbase, Cassandra/Hadoop and others. What do you recommend? What problems have you run into with the ones you've tried?"

First time accepted submitter ControlsGeek (156589) writes "The Raspberry Pi Foundation has developed a new product. It is basically a Raspberry Pi model A processor, memory, and flash memory on a DDR2-style SODIMM connector. Also available will be a development board that breaks out all the internal connections. The board design will be open sourced so you can develop your own devices using the BCM2835 processor. No network, but support for 2 HDMI displays and 2 cameras, so 3D TV is a possibility.
theodp (442580) writes "Over at Microsoft on the Issues, Microsoft continues to lament the computer programming skills gap of American kids, while simultaneously lobbying for more H-1B visas to fill that gap. Saying that states must do more to 'help students gain critical 21st century skills,' Microsoft credits itself and partner Code.org for getting 30,606,732 students to experience coding through the Hour of Code, claiming that K-12 kids have 'written 1,332,784,839 lines of code' (i.e., dragged-and-dropped puzzle pieces), So, if it's concerned about helping students gain programming skills, shouldn't Microsoft be donating fully-functional desktop versions of MS-Office to schools, which would allow kids to use Visual Basic for Applications (VBA)? While Microsoft's pledge to give 12 million copies of its Office software to schools was heralded by the White House and the press, a review of the 'fine print' at Microsoft suggests it's actually the online VBA-free version of Office 365 Education that the kids will be getting, unless their schools qualify for the Student Advantage program by purchasing Office for the faculty and staff. Since Microsoft supported President Obama's call for kids to 'Don't Just Play on Your Phone, Program It', shouldn't it give kids the chance to program MS-Office, too?"
An anonymous reader writes "Linux kernel developers are currently evaluating the possibility of using QR codes to display kernel oops/panic messages. Right now a lot of text is dumped to the screen when a kernel oops occurs, most of which isn't easily archivable by normal Linux end-users. With QR codes as Linux oops messages, a smart-phone could capture the display and either report the error string or redirect them to an error page on Kernel.org. The idea of using QR codes within the Linux kernel is still being discussed by upstream developers."
xyourfacekillerx writes "Not long ago, Slashdot readers answered a question for someone seeking to finish a BS in CS online. I am in a similar situation with a different question. I have spent five years frivolously studying philosophy at a very expensive university, and now I want to start towards an Associate's in CS, and then perhaps a Bachelor's (I want to program for a living; I write code daily anyways). After four hours of combing through Google results, I still don't have much useful information. Problem 1: I am out of money and I have an 8 to 5 job, so on-campus enrollment is not an option. Problem 2: and I have very little to transfer due to the specificity of my prior studies: I don't even have my core English/Language or even math cores to transfer. My questions are: 1) Just where are the open CS courses? Who offers it in a way that's more than just lecture notes posts online? 2) Can any of it help or hinder me getting a degree (i.e. does any of it transfer, potentially? Is it a waste of time? Additionally, any tips about accredited online universities (preferably self-paced) where I can start to get my associates and/or bachelor's in CS at low cost would be useful. I intend to be enrolled online somewhere by Fall, and I am starting my own search among local (Colorado) junior colleges who don't demand on-campus presence like most four-years schools do."
An anonymous reader writes "The F# programming language team has been providing source code releases for years, but all contributions to the core implementation were internal. Microsoft is now changing that. They've announced that they'll be accepting code contributions from the community for the core F# language, the compiler, library, and Visual F# tools. They praised the quality of work currently being done by the F# community: 'The F# community is already doing high-quality, cross-platform open engineering using modern tools, testing methodology and build processes. Some particularly active projects include the Visual F# Power Tools, FSharp.Data, F# Editing Support for Open Editors, the Deedle DataFrame library and a host of testing tools, web tools, templates, type providers and other tools.' Microsoft is actively solicited bug fixes, optimizations, and library improvements."
alphadogg writes: "An argument between developers of some of the most basic parts of Linux turned heated this week, resulting in a prominent Red Hat employee and code contributor being banned from working on the Linux kernel. Kay Sievers, a well-known open-source software engineer, is a key developer of systemd, a system management framework for Linux-based operating systems. Systemd is currently used by several prominent Linux distributions, including two of the most prominent enterprise distros, Red Hat and SUSE. It was recently announced that Ubuntu would adopt systemd in future versions as well. Sievers was banned by kernel maintainer Linus Torvalds on Wednesday for failing to address an issue that caused systemd to interact with the Linux kernel in negative ways."
An anonymous reader writes "By the end of next week, NASA will release a master catalog of over 1,000 software projects it has conducted over the years and will provide instructions on how the public can obtain copies of the source code. NASA's goal is to eventually 'host the actual software code in its own online repository, a kind of GitHub for astronauts.' This follows NASA's release of the code running the Apollo 11 Guidance Computer a few years back. Scientists not affiliated with NASA have already adapted some of NASA's software. 'In 2005, marine biologists adapted the Hubble Space Telescope's star-mapping algorithm to track and identify endangered whale sharks. That software has now been adapted to track polar bears in the arctic and sunfish in the Galapagos Islands.' The Hubble Space Telescope's scheduling software has reportedly also been used to schedule MRIs at hospitals and as control algorithms for online dating services. The possibilities could be endless."
itwbennett (1594911) writes "Hackathons have stirred up their share of controversy — mostly around too-big prizes and the inevitable cheating that follows. But for some developers they also can be the ultimate job interview — not just a coding test, but an opportunity to show off your people skills. Take the case of the January 2014 GlobalHack contest in St. Louis that was initially attended by several hundred programmers. The story of the contest isn't who took away the top $50,000 prize but about the other participants who didn't finish in the money but came away with something else that is arguably more important."

atrader42 (687933) writes "Microsoft announced a new .NET compiler that compiles .NET code to native code using the C++ compiler backend. It produces performance like C++ while still enabling .NET features like garbage collection, generics, and reflection. Popular apps have been measured to start up to 60% faster and use 15% less memory. The preview currently only supports Windows Store applications, but is expected to apply to more .NET applications in the long term. A preview of the compiler is available for download now. (Caveat: I both work for MS and read Slashdot.)"
Nerval's Lobster (2598977) writes "Amazon is serious about conquering the living room: the online retailer has launched Fire TV, a set-top box that not only allows viewers to stream content, but also play games. That streaming-and-gaming capability makes Amazon a threat to Apple, which rumors suggest is hard at work on an Apple TV capable of doing the same things. In addition, Fire TV puts the screws to other streaming hardware, including Roku and Google's Chromecast, as well as smaller game consoles such as Ouya (a $99, Android-based device). Much of Amazon's competitive muscle comes from its willingness to sell hardware for cheap (the Fire TV retails for $99) on the expectation that owners will use it to stream and download digital content from Amazon, including television shows and apps. Those developers who've developed Android games have an advantage when it comes to migrating software to Amazon's new platform. "Porting You Don't Know Jack was really like developing for Android, with the exception of the store and the new controller library," Jackbox Games Designer/Director Steve Heinrich told Gamasutra after the Fire TV announcement. "The store itself is the same as the Kindle version, which we've used many times now, and the way the controller works is very close to what we did for Ouya." While Fire TV could represent yet another opportunity for game developers looking to make a buck, it also raises a pressing question: with so many platforms out there (iOS, PC, etc.), how's an indie developer or smaller firm supposed to allocate time and resources to best advantage?"
Nerval's Lobster writes: "An article in the Harvard Business Review does its best to punch a small hole in the startup-hype balloon. 'Encouraging kids to blow off schoolwork to write apps, or skip college to become entrepreneurs, is like advising them to take their college money and invest it in PowerBall,' Jerry Davis, Wilbur K. Pierpont professor of management at the Ross School of Business and the editor of Administrative Science Quarterly, wrote in that column. 'A few may win big; many or most will end up living with their moms.' Whether or not the unfortunate developer ends up back in the childhood bedroom, it's true that, with millions of apps available across all mobile platforms, it's increasingly difficult for independent developers to stand out. Compounding the problem, some of the hottest companies out there for developers and programmers don't have nearly enough job openings to absorb the flood of graduates from the world's universities. So what's a developer to do? Continue to plow forward, with adjusted expectations: the prospect of becoming the next Mark Zuckerberg is just too tantalizing for many people to pass up, even if the chances of wild success are smaller than anyone rational would like to admit."
bellwould (11363) writes "Our CTO has asked us to move our entire dev/test platform off of shared, off-site, hardware onto Amazon, Savvis or the like. Because we don't know enough about this, we're nervous about the costs like CPU: Jenkins tasks checks-out 1M lines of source, then builds, tests and test-deploys 23 product modules 24/7; as well, several Glassfish and Tomcat instances run integration and UI tests 24/7. Disk: large databases instances packed with test and simulation data. Of course, it's all backed up too. So before we start an in-depth review of what's available, what experiences are dev shops having doing stuff like this in the cloud?"
Sockatume (732728) writes "Would you like to see a half-million-dollar TV show in which four teams of indie developers and Youtube personalities compete to create amazing videogames? Tough luck, because GAME_JAM from Maker Studios has spectacularly imploded. Although a lot could go wrong with this kind of show, the blame isn't being levelled at game developer egos or project mismanagement but the heroic efforts of one Matti Leshem, a branding consultant brought in for Pepsi. After imposing Mountain Dew branding rules that even banned coffee from the set, his efforts to build a gender divide amongst the teams culminated in the competitors downing their tools and the production collapsing. Accounts from Adriel Wallick, Zoe Quinn, and Robin Arnott are also available."

The fourth repo "KDE:Unstable:SC" will offer early builds as they are being devloped."
An anonymous reader writes "Chris Granger, creator of the flexible, open source LightTable IDE, has written a thoughtful article about the nature of programming. For years, he's been trying to answer the question: What's wrong with programming? After working on his own IDE and discussing it with hundreds of other developers, here are his thoughts: 'If you look at much of the advances that have made it to the mainstream over the past 50 years, it turns out they largely increased our efficiency without really changing the act of programming. I think the reason why is something I hinted at in the very beginning of this post: it's all been reactionary and as a result we tend to only apply tactical fixes. As a matter of fact, almost every step we've taken fits cleanly into one of these buckets. We've made things better but we keep reaching local maxima because we assume that these things can somehow be addressed independently. ... The other day, I came to the conclusion that the act of writing software is actually antagonistic all on its own. Arcane languages, cryptic errors, mostly missing (or at best, scattered) documentation — it's like someone is deliberately trying to screw with you, sitting in some Truman Show-like control room pointing and laughing behind the scenes. At some level, it's masochistic, but we do it because it gives us an incredible opportunity to shape our world.'"
