Open Source

Student applications now open for Google Summer of Code!

Google Open Source Blog - Mon, 03/14/2016 - 20:15
Are you a university student looking to learn more about open source software development? Look no further than Google Summer of Code (GSoC) and spend your summer break working on an exciting open source project, learning how to write code.
vertical GSoC logo.jpgFor twelve years running, GSoC gives participants a chance to work on an open source software project entirely online. Students, who receive a stipend for their successful contributions, are paired with mentors who can help address technical questions and concerns throughout the program. Former GSoC participants have told us that the real-world experience they’ve gained during the program has not only sharpened their technical skills, but has also boosted their confidence, broadened their professional network and enhanced their resumes. 

Students who are interested can submit proposals on the  program site now through Friday, March 25 at 19:00 UTC. The first step is to review the 180 open source projects and find project ideas that appeal to you. Since spots are limited, we recommend a strong project proposal to help increase your chances of selection. Our Student Manual provides lots of helpful advice to get you started on choosing an organization and crafting a great application. 

For ongoing information throughout the application period and beyond, see the Google Open Source Blog, join our Google Summer of Code discussion lists or join us on internet relay chat (IRC) at #gsoc on Freenode.

Good luck to all the open source coders out there, and remember to submit your proposals early — you only have until Friday, March 25 at 19:00 UTC to apply!

Goodnight Melange

Google Open Source Blog - Wed, 03/09/2016 - 21:10
The time has come to say farewell to Melange, the website software which ran Google Summer of Code from 2009 to 2015, and Google Code-in from 2010 to 2014. Both programs have migrated to new websites.
Starting on Thursday, March 31, will become a limited static archive of what projects and tasks were completed. It will contain titles, descriptions, and display names, but no other project information. If there is any data from the site you wish to save, you should extract it now. Melange has facilitated over 11,000 students to get involved in open source software development, working on projects big and small. We encourage our users to export the data and keep it alive.
The code for Melange will continue to be open source but Google will not be doing any further development on it. We'd be pleased to hear someone forked the code and continued working on Melange as a new project.

Thanks to everyone who contributed to Melange and kept it running over the past 7 years: Aditi, Akeda, Anatoly, Andrew, Anthony, Arc, Aruna, Ashish, Augie, Chen, Dan, Daniel, David, Denys, Dmitri, Doug, Drew, Felix, Gilles, Jacob, James, Jasvir, Jenn, Johannes, John, Jonn, Kevin, Lennard, Leo, Leon, Madhusudan, Marcelo, Mario, Matthew, Mayank, Nathaniel, Orcun, Pankaj, Pawel, Piotr, Piyush, Praveen, Raul, Robert, Rylan, Savitha, Selwyn, Shikher, Simon, Sriharsha, Suyash, Sverre, Syed, Tim, Tobias, Todd, Vivek and Zachary.

Melange served us well for a long time, and we hope it enjoys its retirement!

libjpeg-turbo is a JPEG image codec that uses SIMD instructions (MMX, SSE2, NEON) to accelerate baseline JPEG compression and decompression on x86, x86-64, and ARM systems. On such systems, libjpeg-turbo is generally 2-4x as fast as libjpeg, all else being equal. On other types of systems, libjpeg-turbo can still outperform libjpeg by a significant amount, by virtue of its highly-optimized Huffman coding routines. In many cases, the performance of libjpeg-turbo rivals that of proprietary high-speed JPEG codecs. libjpeg-turbo implements both the traditional libjpeg API as well as the less powerful but more straightforward TurboJPEG API. libjpeg-turbo also features colorspace extensions that allow it to compress from/decompress to 32-bit and big-endian pixel buffers (RGBX, XBGR, etc.), as well as a full-featured Java interface.

SMPlayer is a free media player for Windows and Linux with built-in codecs that can also play YouTube videos. One of the most interesting features of SMPlayer: it remembers the settings of all files you play. So you start to watch a movie but you have to leave… don’t worry, when you open that movie again it will be resumed at the same point you left it, and with the same settings: audio track, subtitles, volume… SMPlayer is a graphical user interface (GUI) for the award-winning MPlayer, which is capable of playing almost all known video and audio formats. But apart from providing access for the most common and useful options of MPlayer, SMPlayer adds other interesting features like the possibility to play YouTube videos subtitles.

Teaching kids to program in their native language

Google Open Source Blog - Fri, 03/04/2016 - 19:00

Today we introduce two programs to help kids program in their native language — clojure-turtle and clj-thamil. Both are written in Clojure, a dialect of Lisp that runs on the Java Virtual Machine. What makes Clojure unique is its simple design which can help make the path for kids to learn programming easier.
clojure-turtle: a bridge between logo beginners and lisp experts
For some beginners, the Clojure learning curve has been steep in the area of functions and functional programming. Many students learning to program prefer to start instead with Logo, a dialect of Lisp that is used in Scratch and teaching efforts such as We designed clojure-turtle with this in mind.
The clojure-turtle project was created to bridge the gap between the people using Lisp at opposite ends of the spectrum. It’s for those learning to program for the first time and those with “real-world concerns” who write macros. The project implements Logo in Clojure, and remains faithful to the basics of Logo —(forward 10),  (right 90), etc.  But the door is left open for you to blur the lines of Logo/Clojure, beginner/FP, etc.:
(defn square-by-length  [side-length]  (repeat 4 (all (forward side-length) (right 90))))
(defn mirrored [f]  (fn [& args]    (repeat 2 (all (apply f args) (right 180)))))
(def lengths [40 50 60])(map (mirrored square-by-length) lengths)clojure-turtle2.pngOne place where the Logo in Clojure approach of clojure-turtle has already proven successful is in ClojureBridge, a workshop for beginners aimed at increasing the number of people from underrepresented minority groups within the Clojure community. The section on teaching functions had been challenging for students previously, but students now learning through the Logo-based approach move past it with ease onto higher level concepts.
clj-thamil: programming in your native language
When I originally set out to create a library for processing for the Thamil language, I stumbled upon the realization that I could also program in the Thamil language. Functions are first-class data, which can be assigned to new names. But macros are what enable me to “translate” the rest of Clojure from English to Thamil, doing so in the form of a library, without having to modify the compiler, and in a manner that is generic for any language to use. Now, a function to pluralize a word in Thamil can be itself written in Thamil. In my Clojure/West talk on clj-thamil, I talked about the potential impact on increasing diversity among programmers, especially when we consider the number of people globally who do not have access to a (good) English education that is an implicit prerequisite for learning to program.
Putting the two together: learning Logo in your native language
The approach of clj-thamil is flexible and powerful enough that we can “translate” any code, not just the core of Clojure. So why not translate clojure-turtle in less than 30 lines of code? Here is a video demonstrating the use of Logo in the Thamil language:

The simple concepts of Logo soften the learning curve for programming and can make it fun for all ages! The simplicity of Clojure gives it a power that you can use to shape the program to your will — students can write all their code in a non-English language if they want. The combination of simple concepts can make it  possible to teach programming to kids around the world who do not speak English. I hope that clojure-turtle and clj-thamil can be used to improve literacy and diversity for students learning to code.

Lessons We Can Learn from the Linux Mint Hack Front page news - Fri, 03/04/2016 - 06:14

It’s been two weeks since the Linux Mint hacking incident was first reported. It was no doubt a major blow to the project but thankfully, the people behind it have pulled through and taken every measure to ensure this never happens again. It was certainly a learning experience for the developers of the distro, and for the rest of us as well.

So what can we all learn from this? A few things:

1. Anyone can be hacked.
In response to the generally negative views towards Mint and the hacking, many redditors have commented that this event was actually not that shocking. Many of them pointed out that if large companies like Sony experience being breached multiple times despite tight security, how much more distros like Mint? This is not to downplay the issue, but to inform the general public that it’s really a situation that can happen to anyone. Unlike Sony however, Mint had to deal with more negative press than they could handle, which brings us to the next lesson:

2. Manage your press.
Many Mint users agree that although the situation was bad, it received far more bad press than it should have, with plenty of vitriol along with it. It’s difficult to handle such things, but if the entire Linux community gave their full support and Mint had acknowledged and addressed the situation sooner, then perhaps the negative press would have been minimized. Unfortunately, this wasn’t entirely the case.

3. Always be aware.
According to Silviu Stahie of Softpedia, though the Linux Mint team claimed the hacking to be a recent event, they were already given a warning about it a month prior. On January 16 Pieter Vlasblom, a freelance Information Security Engineer and Developer informed the team of the breach via Twitter, and even had an image to prove it. But as we all know now, the team only publicly recognized the existence of hacked ISOs over a month later. Stahie suggests that this may be because the Mint team simply didn’t check their Twitter account often. This just goes to show that it pays to check on all sources of project-related information especially those served on a silver platter, like your own social media pages.

4. Strengthen security.
This is perhaps the most crucial and pertinent lesson of all. Although it started out as a small project, Mint undoubtedly became a very popular distribution. When distros reach this level of popularity it’s crucial for the developers to have the necessary security structures in place. There’s no room for compromise here, especially for a serious distribution like what Mint turned out to be.

March 2016, “Staff Pick” Project of the Month – WinPython Front page news - Thu, 03/03/2016 - 06:00

For our March “Staff Pick” Project of the Month, we selected WinPython, an open-source portable distribution of the Python programming language for Windows XP/7/8. Pierre Raybaut, creator and developer of WinPython, and his current maintainer Big Stone shared their thoughts about the project’s history, purpose, and direction.

SourceForge (SF): What made you start this project?
Pierre Raybaut (PR): In 2008, I was getting tired of working around MATLAB limitations and looking for an alternative to this language/IDE for signal and image processing software development. Apart from the required scientific features that almost all candidates had (MATLAB, IDL, Python, Ruby, F#), it had to be a modern fundamentally-object-oriented high-level language (exit MATLAB, IDL), with advanced GUI features (exit MATLAB, IDL) and a strong scientific community (exit Ruby, F#). Python was the best choice. And, for various reasons, I had to develop applications on Windows. So, I was rapidly confronted with the distribution issue: how to install all Python material necessary to develop my scientific applications? That’s why I’ve created the Python(x,y) project ( a single Windows executable for installing an all-in-one Python-based scientific development environment (Python official distribution plus tons of third-party libraries, the Spyder IDE, compilers like MinGW, and so on). But Python(x,y) was quite invasive in the Windows OS (registry entries, start menu entries, …) and like the official Python distribution, it did not allow to install more than one Python distribution (let’s say Python 2.7 and Python 3.4 for example) without messing with the environment variables. So, in 2012, I’ve decided to act by creating WinPython: a portable distribution of Python, allowing to install a complete functional scientific Python environment without modifying any Windows system setting (registry entries, environment variables, file type associations and start menu shortcuts are not affected ; unless you want to: there is an option for that, allowing to switch easily from a WinPython folder to another) to install multiple Python versions without any interference whatsoever or to run Python from a removable device.

SF: Has the original vision been achieved?
PR: Absolutely. Of course, the distribution process has been improved since 2012 and other interesting features have been added since then but the original vision has been achieved almost since the first release.

SF: Who can benefit the most from your project?
PR: Scientific Python users working on Windows looking for a complete developement environment that can be executed from anywhere with any requirement.

SF: What core need does WinPython fulfill?
PR: Providing a full-featured scientific Python distribution packaged in an all-in-one installer. Installing Python everywhere with or without administrative privileges. Allowing multiple Python installations on a Windows single machine without any interference.

SF: What’s the best way to get the most out of using WinPython?
Big Stone (BS): When you see an error or a missing feature, contribute ‘ideas’/’error report with sample tests’/’patches and pull request’ to the relevant project.

SF: What has your project team done to help build and nurture your community?
BS:WinPython is trying to grow the number of Python-stack satisfied users:

– on Windows also, where most beginners are, by making installation easy,

– on standards (Python 3, pip), where most beginners should be headed to.

It’s about what Jessica Mc Kellar is describing here :

SF: Have you all found that more frequent releases helps build up your community of users?
BS: Each project has a pertinent pace of releases, and that seems between 6 and 12 weeks for WinPython.

SF: What was the first big thing that happened for your project?
BS: It survived a bus factor of 1 (, and remembers it.

SF: What helped make that happen?
BS: Pierre did create a good enough documentation to allow a User to step-in.

At least one user had no better choice than to step in, because of strong investment in WinPython Deployment.

As result, the current maintainer:

– ensures users can even more easily replicate/fork the project, by improving the build documentation and simplifying WinPython

– tries to improve “Python 3 stack on Windows” as a whole, so the specific cost to achieve “WinPython” experience is going down to “feather price”

SF: How has SourceForge and its tools helped your project reach that success?
BS: Sourceforge is well-suited to WinPython because of the following:

– its capacity to propose and distribute quickly the big WinPython distributions,

– its popularty (downloads) follow-up,

– its asked price (free), for this not-easily-sustainable kind of service.

Thank you, Sourceforge.
(You’re very welcome. :-) )

SF: What is the next big thing for WinPython?
BS: A “Feature-complete” WinPython 3.5.

SF: How long do you think that will take?
BS: Between 2 and 6 months, but that’s just a guess.

SF: Do you have the resources you need to make that happen?
BS: NumFocus provides the support to mingwpy “corner-stone” project that is needed for that.

SF: If you had it to do over again, what would you do differently for WinPython?
BS: Dropping dying technologies sooner rather than later.

Users don’t move away from dying technologies until you stop maintaining them.

SF: Is there anything else we should know?
BS: Dream:

– Python 3+ is the preferred user-script system on all Windows,

– Python 3+ “full stack” for non-admin users is on all Windows,

– Winpython is just a “check list of features” over that, if ever it is still needed.

New algorithms may lower the cost of secure computing

Google Open Source Blog - Wed, 03/02/2016 - 19:00
Here at Google we strive to make computing not only more cost-efficient, faster, and easier but also more secure. Hash functions are essential building blocks in computing, but must be protected against certain inputs. Today, we are open-sourcing 3 new hash function implementations: faster, data-parallel versions of SipHash, a fast cryptographically strong pseudorandom function, and the entirely new HighwayHash, which reaches even higher speeds thanks to the data parallel features of modern computers.
Our first hash function produces the same output as SipHash, but 1.5 times as quickly thanks to AVX-2 instructions. The second improvement uses j-lanes tree hashing to process multiple inputs in parallel, which is 3 times as fast. This technique is known to be secure, but produces different output than the original SipHash and is slightly slower for short inputs.
HighwayHash is based on a new way of mixing inputs with just a few AVX-2 multiply and permute instructions. We are hopeful that the result is a cryptographically strong pseudorandom function, but new cryptanalysis methods might be needed for analyzing this promising family of hash functions. HighwayHash is significantly faster than SipHash for all measured input sizes, with about 7 times higher throughput at 1 KiB.
We believe our efforts represent the current state of the art in high-speed attack-resistant hashing. These new functions can lower the cost of safe and secure computing. We invite everyone to use, study, and analyze the open-source implementations.
