Who’s New in Google Summer of Code: Part 2

Friday, June 10, 2011


This is the second in our series of posts this summer highlighting a few of the organizations participating in their first Google Summer of Code. The organizations give a brief description of their project and the tasks the students will be working on this summer.

LanguageTool is one of the very few open source style and grammar checkers. It tries to find errors in a text that a spell checker cannot find. This works by matching the text against pattern rules. If there's a rule for the error, it can be found, if there is no such rule, then it can not be found. There's also the risk that a pattern rule matches text which is actually correct, so the user would get a false alarm. This is where our two student projects come in: one project will be adding more rules by reusing rules from other open source grammar checkers, the second student will develop a way for us to test rules that are still in development against a large amount of text. This way we can fix the false alarms before a release.

The 'Computational Science and Engineering at TU Wien' project develops software for the simulation of a plethora of physical phenomena. Example applications range from fluid dynamics, to the propagation of high frequency waves and electronic devices such as lasers and transistors, to the mechanical stability of human bones.

Our students will be working on the following: Cristina Precup will design a constructive solid geometry input file format that allows users to conveniently specify two-dimensional geometries using boolean operation on primitives such as circles and rectangles. Our second student, Jorge Rodriguez, will investigate a convenient approach to parallelize the volume meshing step for meshes of considerable size. Markus Wagner, our third student, will work on using graphics processing units (GPUs) to accelerate solving the large systems of equations that describe certain physical phenomena.

Learning Unlimited works with over 900 college student volunteers to create educational programs for over 6000 middle and high school students across the US. Our programs invite pre-college students to choose between hundreds of topics like quantum mechanics, urban design, Shakespeare, or street drumming and create an environment where it is socially acceptable to share your excitement about learning. Our open source software automates a lot of the processes for running these programs so that college students can focus on making an awesome weekend for younger students.

We are mentoring two promising students sponsored by Google Summer of Code. Jordan Moldow joins us from MIT, home of the oldest and largest LU chapter; he will be implementing a new student registration system that is easier to use and gives directors more flexibility in implementing application and lottery processes. Jordan is also planning to improve our application's data viewing and export capabilities. Vishal Dugar, from the Birlani Institute of Technology and Science in Pilani, India, has joined us to implement a custom forms builder. This system will act somewhat like Google Forms, but with backend storage in dynamically generated Django models and the ability to link form fields with model fields in the existing schema. These contributions should substantially enhance the ability of our volunteers to coordinate and support unique educational events at a growing number of universities.

YouTube and Creative Commons: raising the bar on user creativity

Monday, June 6, 2011

Have you ever been in the process of creating a video and just needed that one perfect clip to make it pop? Maybe you were creating your own music video and needed an aerial video of Los Angeles at night to spice it up. Unless you had a helicopter, a pretty powerful camera and some fierce editing skills, this would have been a big challenge. Now, look no further than the Creative Commons library accessible through YouTube Video Editor to make this happen. Creative Commons provides a simple way to license and use creative works.

You can now access an ever-expanding library of Creative Commons videos to edit and incorporate into your own projects. To find a video, just search in the YouTube search bar or from within the YouTube Video Editor. We’re working with organizations like C-SPAN, Public.Resource.org, Voice of America, Al Jazeera and others, so that over 10,000 Creative Commons videos are available for your creative use.

To get started, visit youtube.com/editor and select the CC tab:


Any video you create using Creative Commons content will automatically show the source videos’ titles underneath the video player:



As part of the launch of Creative Commons licensing on YouTube, you’ll also be able to mark any or all of your videos with the Creative Commons CC-BY license that lets others share and remix your work, so long as they give you credit. To mark your video with the Creative Commons license, select ‘Creative Commons Attribution license’ on the upload page or on the Video Description page:


You can learn more about Creative Commons on YouTube at our help center, and remember that all content must still follow the rules in our Copyright Center.

We’re excited to see what you come up with!

Who’s New in Google Summer of Code: Part 1

Friday, June 3, 2011



This year we are excited to have 50 organizations participating in their first Google Summer of Code. We asked each of these new organizations to contribute a short description of their project for a series of posts we’ll be running this summer, beginning today.
HelenOS
For some years, we have been developing a microkernel-based multiserver
operating system, which is not quite like the other fish in the pond. HelenOS is designed with hardware portability in mind, so it runs on many different processor architectures, such as SPARC and Itanium to name a few. At the same time, HelenOS is not quite like Unix, which both gives us freedom to design our interfaces as we please and also represents a substantial limitation to what software can be directly added to HelenOS without major modifications.

We are very excited about our acceptance to this year's Google Summer of Code, because through the program, we were given a chance to take our locally popular academic project much further. Two of our three accepted students are from universities with previously zero exposure to HelenOS.

This year, we have a couple of student projects that aim to make the usability gap mentioned above a lot smaller by porting binutils and pcc to HelenOS while enhancing our standard C library in parallel. Having a functional toolchain will take us two steps closer to becoming self-hosting one day. Our third project is focused on improving our FAT file system server and adding support for its many commonly used variants.

illumos is the fully open community fork of the OpenSolaris operating system.

Our goal is to foster open development of technologies for the 21st century while building on a 20 year heritage, but free from the oversight of a single corporate entity and the resulting challenges thereof.

We're thrilled to be part of the 2011 Google Summer of Code, and to have two talented students on board. Harshit Jain is integrating GRUB 2 as our boot loader and Shashank Karkare is rewriting our Perl system tools in C. We also offer mentorship open to anyone through our illumos Students program.

The Freeseer project was created to make recording video extremely easy. It's primary goal was to make recording large conferences with many talks possible on a frugal budget and ensure recordings are high quality. Since its birth in late 2008, Freeseer has evolved to do a very good job of recording talks, presentations, demos, and other video with an intuitive interface and is continuing to mature and develop. We have practical goals for 2011:

1) Improve installation. We want to make Freeseer available on Windows, Linux, MacOS, and *BSD. We want the install experience to be very easy so we've recently been putting work into packaging and thinking about how to simplify software management challenges to get our prerequisites installed on Windows.
2) Live streaming. We want to make sharing content as easy live as it is with recorded videos.
3) We've been approached by organizations that need a solution such as Freeseer to record lectures, meetings, presentations, and so forth. They need features like automatic recording in a given room according to a schedule, automatic uploading of video files after they are recorded, robust and scalable hosting they can count on and voice over IP support so remote participants can participate in the conversation. They are also interested in securing the video feed so it cannot be intercepted or tampered with and a CLI so that one operator could potentially run Freeseer in multiple rooms simultaneously and reduce labor costs.
4) Additional goals we're working on include fancier formats for the video such as adding picture-in-picture support for dual video sources, side by side video, support for an automatic timer based switch between multiple video sources, watermarks/headers/logos, and more.

For Google Summer of Code, our students are working on projects that enable the above goals. Felipe Vieira Falcão is working on adding a shell/command line interface for Freeseer. This enables scheduling, automation, and remote operators. Mathieu Hubbard is working on video uploading capabilities which will make uploading videos automatic after they are recorded and making manual upload much easier.
