R Throwdown Challenge 185

Posted by timothy from the if-you-pirate-it-so-much-the-better dept.
theodp (442580) writes "'R beats Python!' screams the headline at Prof. Norm Matloff's Mad (Data) Scientist blog. 'R beats Julia! Anyone else wanna challenge R?' Not that he has anything against Python, Matloff adds, but he just doesn't believe that Python or Julia will become 'the new R' anytime soon, or ever. Why? 'R is written by statisticians, for statisticians,' explains Matloff. 'It matters. An Argentinian chef, say, who wants to make Japanese sushi may get all the ingredients right, but likely it just won't work out quite the same. Similarly, a Pythonista could certainly cook up some code for some statistical procedure by reading a statistics book, but it wouldn't be quite same. It would likely be missing some things of interest to the practicing statistician. And R is Statistically Correct.'"

Microsoft Office Mix: No-Teacher-Left-Behind Course Authoring 27

Posted by timothy from the it's-just-respecting-their-character-class-as-gatekeepers dept.
theodp (442580) writes "While they aim to democratize learning, the Massive Open Online Course (MOOC) movement has, for the most part, oddly left K-12 teachers out of the online content creation business. ZDNet's Simon Bisson reports on Office Mix, Microsoft's new PowerPoint plug-in and associated cloud service, which Bisson says makes it easy to create and distribute compelling educational content (screenshots). GeekWire's Frank Catalano also makes an interesting case for why Office Mix's choice of PowerPoint, "the poster child for delivering boring presentations in non-interactive settings," could still be a disrupter in the online content creation space. By the way, MOOC.org, the collaboration of edX and Google which also aims to help "teachers easily build and host courses for the world to take," is slated to go live in the first half of 2014. It'll be interesting to see how MOOC.org's authoring tools differ from Google Research's Course Builder effort."

LegoTechno -- Making Music With Lego Bricks, Python, OpenCV and a Groovebox 5

Posted by Soulskill from the not-compatible-with-mega-bloks dept.
bauhausinteraction writes "A team from the Bauhaus-University and Native Instruments Developers built and programmed a fully functional interactive Lego Sequencer / Tangible Groove Machine that sends control data to the Maschine drum sequencer to make music. The thing was built within 24 hours as an unofficial weekend collaboration between bauhausinteraction and NI at the MidiHack 2014 in Stockholm. A standard webcam is mounted underneath the baseplate. The image is processed by a Python Script using the OpenCV Library to track the bricks. The tricky bit was to not track the user's hand, but we succeeded at that as well.

The information about brick color, position, and orientation is derived from the image and then converted into OpenSoundControl (OSC) messages. Those are sent over a network connection to a computer running Native Instruments Maschine to play back the sounds. Of course, this would work with other sound generators as well, since the whole thing simply spits out OSC-Messages and MIDI — but hey: if the guys from Native are there, you'd better use their Maschine stuff. Being real Masterbuilders, of course we used only unmodified, standard Lego Parts and no Kragle* for the construction. (*see the Lego Movie for reference.)"

First time accepted submitter NotInHere (3654617) writes "Mozilla has introduced a new program called MWoS, or 'Mozilla Winter of Security,' to involve university students in security projects. The attending students will write code for a Mozilla security tool during (northern hemisphere) winter. Unlike GSoC, attending it involves no monetary payment, but the student's universities are expected to actively cooperate and to give the students a credit for their work. From the article: 'MWoS is a win for all. Students get a chance to work on real-world security projects, under the guidance of an experienced security engineer. Professors get to implement cutting-edge security projects into their programs. Mozilla and the community get better security tools, which that we would not have the resources to build or improve ourselves.'"

Fixing the Pain of Programming 294

An anonymous reader writes "Light Table is a Kickstarted, open source IDE that's been trying to integrate real-time feedback into code creation. Part of their process has been figuring out how to improve the practice of programming, from top to bottom. They've put up a post about the troublesome aspects of programming that we've learned to deal with and take for granted, but which need solving if programming is to be made accessible for more people. 'Surprisingly, one of the most common difficulties we have heard from beginners is just running code. Even if we were to hand [a new programmer the whole source code] they would likely still struggle to actually use it. They have to install dependencies, compile code, start servers and open ports. At each step the errors are difficult to diagnose and time-consuming to fix.' But these problems extend to experienced coders, too: 'The simplest question we could ask about our application is "what is the current state." Bizarrely, very few programming environments give you any help on this front. Many programmers get by with nothing but print statements.' It's interesting to see somebody working on these issues, instead of accepting that they're the status quo and just part of the experience of programming."

The Technical Difficulty In Porting a PS3 Game To the PS4 152

Posted by Soulskill from the more-than-you-bargained-for dept.
An anonymous reader writes "The Last of Us was one of the last major projects for the PlayStation 3. The code optimization done by development studio Naughty Dog was a real technical achievement — making graphics look modern and impressive on a 7-year-old piece of hardware. Now, they're in the process of porting it to the much more capable PS4, which will end up being a technical accomplishment in its own right. Creative director Neil Druckmann said, 'Just getting an image onscreen, even an inferior one with the shadows broken, lighting broken and with it crashing every 30 seconds that took a long time. These engineers are some of the best in the industry and they optimized the game so much for the PS3's SPUs specifically. It was optimized on a binary level, but after shifting those things over [to PS4] you have to go back to the high level, make sure the [game] systems are intact, and optimize it again. I can't describe how difficult a task that is. And once it's running well, you're running the [versions] side by side to make sure you didn't screw something up in the process, like physics being slightly off, which throws the game off, or lighting being shifted and all of a sudden it's a drastically different look. That's not 'improved' any more; that's different. We want to stay faithful while being better.'"

Here's a guy who hires and manages programmers, and he says it's not about age at all — it's about skills, period. 'It's each individual's responsibility to stay fresh in the field and maintain a modern-day skillset that gives any 28-year-old a run for his or her money. ... Although the ability to learn those skills is usually unlimited, the available time to learn often is not. "Little" things like family dinners, Little League, and home improvement projects often get in the way. As a result, we do find that we face a shortage of older, more seasoned developers. And it's not because we don't want older candidates. It's often because the older candidates haven't successfully modernized their developer skills.' A company that actively works to offer all employees the chance to learn and to engage with modern technologies is a company that good people are going to work for, and to stay at."

Finding More Than One Worm In the Apple 116

Posted by timothy from the looking-deeper dept.
davecb (6526) writes "At Guido von Rossum's urging, Mike Bland has a look at detecting and fixing the "goto fail" bug at ACM Queue. He finds the same underlying problem in both in the Apple and Heartbleed bugs, and explains how to not suffer it again." An excerpt: "WHY DIDN'T A TEST CATCH IT? Several articles have attempted to explain why the Apple SSL vulnerability made it past whatever tests, tools, and processes Apple may have had in place, but these explanations are not sound, especially given the above demonstration to the contrary in working code. The ultimate responsibility for the failure to detect this vulnerability prior to release lies not with any individual programmer but with the culture in which the code was produced. Let's review a sample of the most prominent explanations and specify why they fall short. Adam Langley's oft-quoted blog post13 discusses the exact technical ramifications of the bug but pulls back on asserting that automated testing would have caught it: "A test case could have caught this, but it's difficult because it's so deep into the handshake. One needs to write a completely separate TLS stack, with lots of options for sending invalid handshakes.""

Could High Bay-Area Prices Make Sacramento the Next Big Startup Hub? 190

Posted by timothy from the cost-of-living-is-important dept.
waderoush (1271548) writes "Don't laugh. As the cost of housing spirals out of control on the San Francisco peninsula, neighboring metro regions like Sacramento are beginning to look more attractive to startup founders who prefer a Northern California lifestyle but haven't worked in the Silicon Valley gold mines long enough to become 1-percenters. Today Xconomy presents Part 1 of a two-part look at innovation in the Sacramento-Davis corridor and efforts to make the region more welcoming to high-tech entrepreneurs. In Sacramento's favor, there's a talented workforce fueled by a top-20 university (UC Davis), space for expansion, proximity to the ski mountains at Tahoe, and a far lower cost of living — the average house in Sacramento is selling for $237,000, compared to $909,000 in San Francisco. The downsides include a shortage of local investment dollars and a lower density of startups, meaning there's less opportunity for serendipitous collaboration. But locals say recent efforts to boost the local high-tech economy are working. 'I really feel like we are in a renaissance area,' says Eric Ullrich, co-founder of Hacker Lab, a Midtown Sacramento co-working space."

If history is any indication, it will take a cultural phenomenon to shift the percentage higher: Blogger Phil Johnson point out that there were 'two distinct peaks, one in 1985 (4.4% of U.S. college degrees) and one in 2002 (4.42%). These would represent big increases for the classes entering school in 1981 and 1998 respectively. The former year corresponds to the beginning of computers coming into the home and the release of things like MS-DOS 1.0, all of which may have increased interest in programming. The latter year was during the dot com bubble, which, no doubt, also boosted interest.'"

Should The Art of Computer Programming, Design Patterns, or Structure and Interpretation of Computer Programs be on the list? What about The Mythical Man-Month, or similar works that are about concepts relating to programming? Is there any code that every programmer should take a look at? Obviously, the nature of this question precludes articles about the nitty-gritty of particular languages, but I'm sure a lot of people would be interested in those, too. So if you can think of a few articles that every C++ programmer (or Perl, or Haskell, or whatever) should know, post those too."

WebKit Unifies JavaScript Compilation With LLVM Optimizer 170

Posted by Soulskill from the like-peanut-butter-and-javascript dept.
An anonymous reader tips this post at Webkit.org: "Just a decade ago, JavaScript – the programming language used to drive web page interactions – was thought to be too slow for serious application development. But thanks to continuous optimization efforts, it's now possible to write sophisticated, high-performance applications – even graphics-intensive games – using portable standards-compliant JavaScript and HTML5. This post describes a new advancement in JavaScript optimization: the WebKit project has unified its existing JavaScript compilation infrastructure with the state-of-the-art LLVM optimizer. This will allow JavaScript programs to leverage sophisticated optimizations that were previously only available to native applications written in languages like C++ or Objective-C. ... I'm happy to report that our LLVM-based just-in-time (JIT) compiler, dubbed the FTL – short for Fourth Tier LLVM – has been enabled by default on the Mac and iOS ports. This post summarizes the FTL engineering that was undertaken over the past year. It first reviews how WebKit's JIT compilers worked prior to the FTL. Then it describes the FTL architecture along with how we solved some of the fundamental challenges of using LLVM as a dynamic language JIT. Finally, this post shows how the FTL enables a couple of JavaScript-specific optimizations."

Ask Slashdot: Minimum Programming Competence In Order To Get a Job? 466

First time accepted submitter Wisecat (3651085) writes "So we all know that computer programming jobs are hot right now. Heck, even President Obama has been urging Americans to learn the skill. But all of us in tech know that not everyone can hack it, and what's more it takes a while to learn anything, and keep up your skills as technology changes. Add to that the fact that companies (and their hiring managers) are always looking for 'the best of the best of the best' talent, and one starts to wonder: just how good does one actually have to BE to get hired? Certainly, there must be plenty of jobs where a level 7/10 programmer would be plenty good enough, and even some that a level 5/10 would be enough. And perhaps we can agree that a level 2/10 would not likely get hired anywhere. So the question is: given that we have such huge demand for programmers, can a level 5, 6, or 7 ever get past the hiring manager? Or is he doomed to sit on the sidelines while the position goes unfilled, or goes to someone willing to lie about their skill level, or perhaps to an H1-B who will work cheaper (but not necessarily better)? I'm a hardware engineer with embedded software experience, and have considered jumping over to pure software (since there are so many jobs, so much demand) but at age 40, and needing to pick a language and get good at it, I wonder whether it would even be possible to get a job (with my previous work experience not being directly related).

Reading, Writing, Arithmetic, and Lately, Coding 125

Posted by samzenpus from the show-and-tell dept.
theodp (442580) writes "The NY Times reports that the national educational movement in computer coding instruction is growing at Internet speeds. 'There's never been a move this fast in education,' said Elliot Soloway, a professor of education and computer science at the Univ. of Michigan. But, cautions the NY Times' Matt Richtel, it is not clear that teaching basic computer science in grade school will beget future jobs or foster broader creativity and logical thinking, as some champions of the movement are projecting. And particularly for younger children, the activity is more like a video game — better than simulated gunplay, but not likely to impart actual programming skills. 'Some educators worry about the industry's heavy role,' adds Richtel. 'Major tech companies and their founders, including Bill Gates and Facebook's Mark Zuckerberg, have put up about $10 million for Code.org,' which recently announced its CS programs will be rolled out to more than 2 million students — nearly 5% of all U.S. K-12 students — at 30 school districts this fall. Among the 20,000 teachers who Code.org says have signed on is Alana Aaron, a fifth-grade math and science teacher who, with her principal's permission, swapped a two-month earth sciences lesson she was going to teach on land masses for the Code.org curriculum. 'Computer science is big right now — in our country, the world,' she said. 'If my kids aren't exposed to things like that, they could miss out on potential opportunities and careers.'"
