Canonical Announces Ubuntu App Showdown 56

alphadogg writes "Linux developers will soon have a chance to compete for prizes of laptops and smartphones, thanks to Canonical's announcement this week of the Ubuntu App Showdown contest. Developers will have from June 18 until July 9 — a total of three weeks — to create an app using Canonical's Quickly development tool, which combines Python and GTK into a single Ubuntu-centric package. The resulting apps will be judged by a five-member panel, with the developers of the top three receiving new Nokia N9 smartphones."

Google Blockly — a Language With a Difference 141

mikejuk writes "There are aspects of Google that increasingly don't make sense. First they dump App Inventor — a graphical language for Android apps — in a fit of spring cleaning and closures — and now they have launched another Scratch-like graphical language, Blockly. However Blockly is different. It works like Scratch or App inventor but it is written in JavaScript. This means it can be included in any web page or web app very easily. This, in turn, means that it can be used for education, getting people to learn to program, or as an easy-to-use script generator for the app. The FAQ gives the example of automating GMail filters and management. The additional difference is that Blockly can compile its programs to JavaScript, Dart or Python so you can take the script and develop it further. This is a really good idea. As long as Google doesn't throw this one out in a fit of reorganization and spring cleaning, it's a welcome new language."

Samba 4 Enters Beta 170

rayk_sland writes "Progress is being made on the long awaited Samba 4 release. On Tuesday the Samba 4 team announced their first beta. Those of us who refuse to have a closed-source server at the core of our networks will be encouraged to see this milestone. Here are a few of the new features: 'Samba 4.0 beta supports the server-side of the Active Directory logon environment used by Windows 2000 and later, so we can do full domain join and domain logon operations with these clients. ... Samba 4.0 beta ships with two distinct file servers. We now use the file server from the Samba 3.x series 'smbd' for all file serving by default. For pure file server work, the binaries users would expect from that series (nmbd, winbindd, smbpasswd) continue to be available. Samba 4.0 also ships with the 'NTVFS' file server. This file server is what was used in all previous alpha releases of Samba 4.0, and is tuned to match the requirements of an AD domain controller. We continue to support this, not only to provide continuity to installations that have deployed it as part of an AD DC, but also as a running example of the NT-FSA architecture we expect to move smbd to in the longer term. ... Finally, a new scripting interface has been added to Samba 4, allowing Python programs to interface to Samba's internals, and many tools and internal workings of the DC code is now implemented in python.'"

Barter-Based School Catching On Globally 118

sethopia writes "In 2010, three people had the crazy idea to start a school where the teachers teach whatever they want and the students pay for classes with whatever teachers need — cutlery, art, advice — but never with money. Trade Schools have been popping up around the world and are now active in 15 cities and 10 countries, with almost no prodding from its founders. Caroline Woolard, one of the founders, discusses the challenges and opportunities of adapting their idea to an international audience and making the Trade School software — based on Python and Django — great."

Comparing R, Octave, and Python for Data Analysis 61

Here is a breakdown of R, Octave and Python, and how analysts can rely on open-source software and online learning resources to bring data-mining capabilities into their companies. The article breaks down which of the three is easiest to use, which do well with visualizations, which handle big data the best, etc. The lack of a budget shouldn't prevent you from experiencing all the benefits of a top-shelf data analysis package, and each of these options brings its own set of strengths while being much cheaper to implement than the typical proprietary solutions.

SciRuby: Science and Matrix Libraries For Ruby 138

Aciel writes "Ruby has long been popular in the web/business community, while Python dominates the scientific community. One new project seeks to bring balance to the force: SciRuby. We've already introduced a linear algebra library called NMatrix (currently alpha status). There's at least one fellowship available for students interested in working on the project this summer."

GNU Media Goblin 0.3.0 Released 43

A mere year since the Mediagoblin photo/video sharing project was started, the project has hit version 0.3.0. Release highlights include: a rewrite of the database from MongoDB to SQL (via SQLAlchemy, making it much easier to install), audio support (using the HTML5 <audio> tag), a first take on a mobile interface, and smarter video buffering. Not content to sit idle, the developers are starting work on Salmon protocol support to federate with software like Diaspora in the next release.

Oracle and the End of Programming As We Know It 577

An anonymous reader writes "An article at Dr. Dobb's looks into the consequences of a dangerous idea from Oracle during their legal battle with Google: 'that Google had violated Oracle's Java copyrights by reimplementing Java APIs in Android.' The issue is very much unsettled in the courts, but the judge in this case instructed the jury to assume the APIs were copyrightable. 'In a nutshell, if the jury sides with Oracle that the copyrights in the headers of every file of the Java source base apply specifically to the syntax of the APIs, then Oracle can extract payment and penalties from Google for having implemented those APIs without Oracle's blessing (or, in more specific terms, without a license). Should this come to pass, numerous products will suddenly find themselves on an uncertain legal standing in which the previously benign but now newly empowered copyright holders might assert punitive copyright claims. Chief among these would be any re-implementation of an existing language. So, Jython, IronPython, and PyPy for Python; JRuby, IronRuby, and Rubinius for Ruby; Mono for C# and VB; possibly C++ for C, GCC for C and C++ and Objective-C; and so forth. And of course, all the various browsers that use JavaScript might owe royalties to the acquirers of Netscape's intellectual property.'"

C/C++ Back On Top of the Programming Heap? 611

Drethon writes "On this day in 2008, a submission was posted that C/C++ was losing ground so I decided to check out its current state. It seems that C has returned to the top while Java has dropped by the same amount, VB and PHP have dropped drastically, C++ is holding fast but now in third place and Objective-C and C# have climbed quite a bit. 2008 data thanks to SatanicPuppy: 1. Java (20.5%); 2. C (.14.7%); 3. VB (11.6%); 4. PHP (10.3%); 5. C++ (9.9%); 6. Perl (5.9%); 7. Python (4.5%); 8. C# (.3.8%); 9. Ruby(2.9%); 10. Delphi (2.7%). The other 10 in the top 20 are: JavaScript, D, PL/SQL, SAS, Pascal, Lisp/Scheme, FoxPro/xBase, COBOL, Ada, and ColdFusion."

Parlez-vous Python? 164

Hugh Pickens writes "The NY Times reports that the market for night classes and online instruction in programming and Web construction is booming, as those jumping on board say they are preparing for a future in which the Internet is the foundation for entertainment, education and nearly everything else. Knowing how the digital pieces fit together will be crucial to ensuring that they are not left in the dark ages. 'Inasmuch as you need to know how to read English, you need to have some understanding of the code that builds the Web,' says Sarah Henry, 39, an investment manager who took several classes, including some in HTML, the basic language of the Web, and WordPress, a blogging service. 'I'm not going to sit here and say that I can crank out a site today, but I can look at basic code and understand it. I understand how these languages function within the Internet.' The blooming interest in programming is part of a national trend of more people moving toward technical fields. 'To be successful in the modern world, regardless of your occupation, requires a fluency in computers,' says Peter Harsha. 'It is more than knowing how to use Word or Excel but how to use a computer to solve problems.' However seasoned programmers say learning how to adjust the layout of a Web page is one thing, but picking up the skills required to develop a sophisticated online service or mobile application is an entirely different challenge that cannot be acquired by casual use for a few hours at night and on the weekends."

Militarizing Your Backyard With Python and AI 112

mikejuk writes "Kurt Grandis took some cutting edge and open source AI tools, Python, an Arduino and a SuperSoaker and built the (almost) perfect squirrel hosing machine. The project involved Open Computer Vision (OpenCV), an a SVM learning procedure that he trained to tell the difference between a squirrel and a non-squirrel. After 'perfecting' the classifier the hardware came next — a SuperSoaker Mark I was used as the 'water cannon.' A pair of servos were used to aim the gun and a third to pull the trigger."

Ask Slashdot: Finding an IT Job Without a Computer-Oriented Undergraduate Degree 504

An anonymous reader writes "Contrary to what many individuals think, not everybody on Slashdot went to college for a computer-related degree. Graduating in May of this year, my undergraduate degree will be in psychology. Like many undergraduate psychology students, I applied to a multitude of graduate programs but, unfortunately, was not given admission into a single one. Many are aware that a bachelor's degree in psychology is quite limiting, so I undoubtedly have been forced into a complicated situation. Despite my degree being in psychology, I have an immense interest in computers and the typical 'hard science' fields. How can one with a degree that is not related to computers acquire a job that is centered around computers? At the moment, I am self-taught and can easily keep up in a conversation of computer science majors. I also do a decent amount of programming in C, Perl, and Python and have contributed to small open source projects. Would Slashdot users recommend receiving a formal computer science education (only about two years, since the nonsensical general education requirements are already completed) before attempting to get such a job? Anybody else in a similar situation?"

Van Rossum: Python Not Too Slow 510

snydeq writes "Python creator Guido van Rossum discusses the prospects and criticisms of Python, noting that critics of Python performance should supplement with C/C++ rather than re-engineering Python apps into a faster language. 'At some point, you end up with one little piece of your system, as a whole, where you end up spending all your time. If you write that just as a sort of simple-minded Python loop, at some point you will see that that is the bottleneck in your system. It is usually much more effective to take that one piece and replace that one function or module with a little bit of code you wrote in C or C++ rather than rewriting your entire system in a faster language, because for most of what you're doing, the speed of the language is irrelevant.'"

New Programming Languages Come From Designers 435

eldavojohn writes "A very lengthy and somewhat meandering essay from Crista Videira Lopes has sparked off some discussion of where new programming languages come from. She's writing from the viewpoint of academia, under the premise that new languages don't come from academia. And they've been steadily progressing outside of large companies (with the exception of Java and .NET) into the bedrooms and hobbies of people she identifies as 'designers' or 'lone programmers' instead of groups of 'researchers.' Examples include PHP by Rasmus Lerdorf, JavaScript by Brenden Eich, Python by Guido van Rossum and — of course — Ruby by Yukihiro Matsumoto. The author notes that, as we escape our computational and memory bounds that once plagued programming languages in the past and marred them with ultra efficient syntax in the name of hardware, our new languages are coming from designers with seemingly little worry about the budget CPU being able to handle a large project in the new language. The piece is littered with interesting assertions like 'one striking commonality in all modern programming languages, especially the popular ones, is how little innovation there is in them!' and 'We require scientific evidence for the claimed value of experimental drugs. Should we require scientific evidence for the value of experimental software?' Is she right? Is the answer to studying modern programming languages to quantify their design as she attempts in this post? Given the response of Slashdot to Google's Dart it would appear that something is indeed missing in coercing developers that a modern language has valid offerings worthy of their time."

Ask Slashdot: Do Kids Still Take Interest In Programming For Its Own Sake? 276

nirgle writes "I have been wondering lately if there are any kids interested in programming for its own sake anymore. When I was my nephew's age, computers were still fascinating: There wasn't a laptop on every table, facebook wasn't splattered on every screen, and you couldn't get any question answered in just a couple seconds with Google. When I was 10, I would have done anything for a close programming mentor instead of the 5-foot high stack of books that I had to read cover-to-cover on my own. So I was happy when my nephew started asking about learning to do what "Uncle Jay does." Does the responsibility now shift to us to kindle early fires in computer science, or is programming now just another profession for the educational system to manage?" Another reader pointed out a related post on the Invent with Python blog titled "Nobody wants to learn how to program."

Stroustrup Reveals What's New In C++ 11 305

snydeq writes "Bjarne Stroustrup discusses the latest version of C++, which, although not a major overhaul, offers many small upgrades to appeal to different areas of development. From the interview: 'I like the way move semantics will simplify the way we return large data structures from functions and improve the performance of standard-library types, such as string and vector. People in high-performance areas will appreciate the massive increase in the power of constant expressions (constexpr). Users of the standard library (and some GUI libraries) will probably find lambda expressions the most prominent feature. Everybody will use smaller new features, such as auto (deduce a variable's type from its initializer) and the range-for loop, to simplify code.'"

2011's Fastest Growing Language: Objective-C 356

mikejuk writes "Every January, it is traditional to compare the state of programming language usage as indicated by the TIOBE index. So what's up and what's down this year? The top language is still Java, but it's slowly falling in the percentages. Objective-C experienced the most growth, followed by C# and C. JavaScript climbed back into the top 10, displacing Ruby. Python and PHP experienced the biggest drops. If you like outside runners, then cheer for Lua and R, which have just entered the top 20. However, I have to wonder why Logo is in the top 20 as well. I know programming education is becoming important, but Logo?"
