New submitter NeoHermit writes "This language (Dao) has never been mentioned on Slashdot before, but it might be interesting to many people here. As it has recently become feature-complete and just made its first beta release, it may be the right time to mention it here. Dao is an optionally-typed programming language that supports many advanced features with a small runtime. The feature list is probably as long as that of Python, but they are supported by a much smaller runtime (somewhere between Lua and Python, but closer to Lua). Besides optional typing, the other major features that worth mentioning include: built-in support for concurrent programming for multicore computers, very friendly C programming interfaces for embedding and extending, a LLVM-based JIT compiler, a Clang-based module for embedding C/C++ codes in Dao, and a Clang-based tool for automatic binding generation from C/C++ header files. You can also see many familiar features from other languages."
First time accepted submitter rarkian writes "I am the teacher in this story. I teach Python and C++ to high school students: grades 9-12. I use CentOS 6 with DRBL to run my computer lab. Some of my students have become Linux experts. Next year I'm planning on allowing students to create and run their own VMs in a segregated LAN. Any advice on which virtualization technology to use and security concerns with allowing students to be root in a VM?"
itwbennett writes "Whoever said 'everyone has to start somewhere' has clearly never tried contributing to an open source project — the Linux Kernel development team in particular is known for its savagery. But if you're determined to donate your time and talents, there are some things you can do to get off on the right foot. Of course you should pick something you're interested in and that you use. Check, and double check. You should also research the project, learn about the process for contributing, and do your utmost to avoid asking questions that you can find the answers to. But beyond that there are some hallmarks of beginner-friendly open source projects like Drupal, Python, and LibreOffice — namely, a friendly and active community, training and mentorship programs, and a low barrier to entry."
theodp writes "In a widely-read WSJ Op-Ed, English major Kirk McDonald, president of online ad optimization service PubMatic, informed college grads that he considers them unemployable unless they can claim familiarity with at least two programming languages. 'Teach yourself just enough of the grammar and the logic of computer languages to be able to see the big picture,' McDonald advises. 'Get acquainted with APIs. Dabble in a bit of Python. For most employers, that would be more than enough.' Over at Typical Programmer, Greg Jorgensen is not impressed. 'I have some complaints about this "everyone must code" movement,' Jorgensen writes, 'and Mr. McDonald's article gives me a starting point because he touched on so many of them.'"
mask.of.sanity writes "A researcher has found that Apple user locations can be potentially determined by tapping into Apple Maps and he has created a Python tool to make the process easier. iSniff GPS accesses Apple's database of wireless access points, which is collected by iPhones and iPads that have GPS and Wi-Fi location services enabled. Apple uses this crowd-sourced data to run its location services; however, the location database is not meant to be public. You can download the tool via Giuthub."
An anonymous reader writes "While complementing Debian APT/DPKG, Canonical is now developing their own package format. The new package format has promised highlights of having no dependencies between applications, each package would install to its own directory, root support wouldn't always be required, and overall a more self-contained and easier approach for developers than it stands now for Debian/Ubuntu packages. The primary users of the new packaging system would be those distributing applications built on the Ubuntu Touch/Phone SDK. The initial proof-of-concept package management system is written in Python and uses JSON representation." This quote from the post by Canonical's Colin Watson bears repeating: "We'll continue to use dpkg and apt for building the Ubuntu operating system, syncing with Debian, and so on."
crookedvulture writes "AMD has revealed more details about the unified memory architecture of its next-generation Kaveri APU. The chip's CPU and GPU components will have a shared address space and will also share both physical and virtual memory. GPU compute applications should be able to share data between the processor's CPU cores and graphics ALUs, and the caches on those components will be fully coherent. This so-called heterogeneous uniform memory access, or hUMA, supports configurations with either DDR3 or GDDR5 memory. It's also based entirely in hardware and should work with any operating system. Kaveri is due later this year and will also have updated Steamroller CPU cores and a GPU based on the current Graphics Core Next architecture." bigwophh writes links to the Hot Hardware take on the story, and writes "AMD claims that programming for hUMA-enabled platforms should ease software development and potentially lower development costs as well. The technology is supported by mainstream programming languages like Python, C++, and Java, and should allow developers to more simply code for a particular compute resource with no need for special APIs."
Rambo Tribble writes "This new, third edition of Sobell's book brings enhancements that add to the text's value as both a learning tool and a reference. This has always been a foundation book for those wanting a professional level of familiarity with Linux. The addition of chapters to introduce the Python language and MySQL database serves to offer the reader practical insights into additional Linux-related technologies." Read below for the rest of Rambo's review.
theodp writes "Its Code of Conduct describes PyCon as 'a welcoming, friendly event for all.' But will the post-conference fallout from this year's 'Donglegate' debacle and proposed remedies affect your decision — one way or the other — to attend next year's PyCon in ironically naughty Montreal? And even if not, could 'Donglegate' influence the-powers-that-be whose approval you'll need to attend? How about conference sponsors?"
XWWT writes "A few weeks ago Make offered to send us a sample of its Raspberry Pi Starter Kit to see if we would do a review of the product. Samzenpus asked around the engineering team to see if there was someone who would be willing to do an on-camera review of the device. With all of the buzz about Raspberry Pi, I was very excited to get hands-on time with the device so I could more closely examine the platform. At first we wanted to do this piece as a video but quickly realized that a) it would probably be boring to see some blinky lights and push buttons working on a sample project, and b) the amount of audio that would need to be bleeped to cover my frustration with parts of the kit would be annoying. On a personal note, I also wanted to document all of my experience here as I thought it would be beneficial for newcomers to the maker technology and sometimes having someone else’s experience documented can help you avoid pitfalls and mistakes. (Full Disclosure: I am the Director of Engineering for Slashdot Media. We were given a review copy of the Make: Raspberry Pi Starter Kit. We were not paid for this review but had fun doing it.)"

Mrs. Grundy writes "When creative professionals want to visualize colors in three dimensions, they often use dedicated and sometimes expensive software. Photographer Mark Meyer shows how, with the help of its Python scripting interface, you can create graphics of color models in Blender. He demonstrates plotting in XYZ, LAB, and xyY space, and also includes the Blender file to show how it's done."
dstates writes "ProPublica, the award winning public interest journalism group and frequently cited Slashdot source, has published an interesting guide to app technology for journalism and a set of data and style guides. Journalism presents unique challenges with potentially enormous but highly variable site traffic, the need to serve a wide variety of information, and most importantly, the need to quickly develop and vet interesting content, and ProPublica serves lots of data sets in addition to the news. They are also doing some cool stuff like using AI to generate specific narratives from tens of thousands of database entries illustrating how school districts and states often don't distribute educational opportunities to rich and poor kids equally. The ProPublica team focuses on some basic practical issues for building a team, rapidly and flexibly deploying technology and insuring that what they serve is correct. A great news app developer needs three key skills: the ability to do journalism, design acumen and the ability to write code quickly — and the last is the easiest to teach. To build a team they look to their own staff rather than competing with Google for CS grads. Most news organizations use either Ruby on Rails or Python/Django, but more important than which specific technology you choose is to just pick a server-side programming language and stick to it. Cloud hosting provides news organizations with incredible flexibility (like increasing your capacity ten-fold for a few days around the election and then scaling back the day after), but they're not as fast as real servers, and cloud costs can scale quickly relative to real servers. Maybe a news app is not the most massive 'big data' application out there, but where else can you find the challenge of millions of users checking in several times a day for the latest news, and all you need to do is sort out which of your many and conflicting sources are providing you with straight information? Oh, and if you screw up, it will be very public."
A couple of weeks ago you had the chance to ask Khan Academy lead developer Ben Kamens about the future of online education and the academy itself. Below you'll find his answers to the questions we sent and a few extra that he found interesting.
WebMink writes "Is it possible that the CEO of the company that's trying to file a trademark on 'Python' was unaware of Python's importance as a programming technology? That's what he claims — despite running a hosting company that's trying to break into cloud computing, where Python is used extensively. Still, he also regards the Python Software Foundation as a hostile American company and thinks that getting attention from half the world's geeks is a DDoS. From the article: '[The CEO, Tim Poultney,] confirmed that he'd not involved any technical staff in the decisions he'd made about the Python product brand, and told me he regretted that as it would probably have helped him understand the likely reaction to his trademark challenge. ... He said he now understood how offended the global developer community are and told me there was obviously only one outcome that was now possible.'"
mvar writes "A company in the UK is trying to trademark the 'Python' term for all things computing. The Python Software Foundation is asking for help. According to the PSF, they contacted the company in order to settle the matter but 'They blew us off and responded by filing the community trademark application claiming the exclusive right to use "Python" for software, servers, and web services — everywhere in Europe.' They now seek help from the community in several ways: By sending a letter to the EU council if you happen to work on a company that uses the Python programming language, by providing EU-published material regarding the Python language (articles etc) and/or financially supporting the PSF in the upcoming legal battle."
itwbennett writes "DARPA (the U.S. Defense Advanced Research Projects Agency) has awarded $3 million to software provider Continuum Analytics to help fund the development of Python's data processing and visualization capabilities for big data jobs. The money will go toward developing new techniques for data analysis and for visually portraying large, multi-dimensional data sets. The work aims to extend beyond the capabilities offered by the NumPy and SciPy Python libraries, which are widely used by programmers for mathematical and scientific calculations, respectively. The work is part of DARPA's XData research program, a four-year, $100 million effort to give the Defense Department and other U.S. government agencies tools to work with large amounts of sensor data and other forms of big data."
sciencehabit writes "A quick visit to Monty Python's Ministry of Silly Walks shows just how many ways humans (or at least British comedians) can think of to travel from point A to point B. So why don't we high kick our way to the bus stop or skip to the grocery store? New research suggests that there may be a deep biomechanical reason governing the gaits we choose in different situations. In short, people consistently choose to walk when they need to travel slower than 2 m/s to reach their goal in the given time; when they needed to move about 3 m/s or faster, they ran. But in between—in 'the twilight zone between walking and running'—people tended to mix the two gaits, minimizing their energy expenditure. The findings could help scientists design better prosthetic limbs and even build more human-like robots"
Matt Steelblade writes "I've been in love with computers since my early teens. I took out books from the library and just started messing around until I had learned QBasic, then Visual Basic 5, and how to take apart a computer. Fast forward 10 years. I'm a very recent college graduate with a BA in philosophy (because of seminary, which I recently left). I want to get into IT work, but am not sure where to start. I have about four years experience working at a grade/high school (about 350 computers) in which I did a lot of desktop maintenance and some work on their AD and website. At college (Loyola University Chicago) I tried to get my hands on whatever computer courses I could. I ended up taking a python course, a C# course, and data structures (with python). I received either perfect scores or higher in these courses. I feel comfortable in what I know about computers, and know all too well what I don't. I think my greatest strength is in troubleshooting. With that being said, do I need more schooling? If so, should I try for an associate degree (I have easy access to a Gateway technical college) or should I go for an undergraduate degree (I think my best bet there would be UW-Madison)? If not, should I try to get certified with CompTIA, or someone else? Or, would the best bet be to try to find a job or an internship?"
