Idea list for GSoC 2013

Applications for desktop end users

These are coding projects that benefit end users of the Linux desktop.

Integrate Proxy Settings and Network Connections(Locations)

Status: Proposed

Summary of idea: The system should use an appropriate networking profile (e.g. Proxy settings) for each network connection.

Gnome 2 had a concept of network locations in its Network Proxy configuration window. However, user should selected the appropriate location whenever he moves between networks. This idea is about providing an integration between NetworkManager and Desktop environments so that a user can create network profiles for each network location(connection) providing appropriate settings like proxy settings which is the main proposed setting here. NetworkManager can have a "Network Location" concept: for wireless networks, usually the name of the network (ESSID) is usually enough. For wired connections, DHCP servers can and usually do provide network's domain name, which can be used as the name of the location. It is nice if a user can associate each network location with a network settings profile which will be used whenever the user is connected to that network automatically. So, when you connect to a network, a corresponding network settings profile is activated automatically.

Knowledge prerequisite:

Skill level:

Contacts: Hedayat Vatankhah

Mentor(s):

Notes: There is an entry with some description in NetworkManager TODO which should be considered for the implementation


Web hosting control panel

Status: Proposed - Draft

Summary of idea: develop a free alternative of cpanel / plesk control panels, 100% compatible with fedora, and redhat enterprise Linux. written in python.

the control panel will be able to create domains and automatically setup apache, postfix, dovecot, mysql, postgresql bind etc...

Knowledge prerequisite: apache, postfix, dovecot, mysql, postgresql, proftpd, bind

Skill level: Medium

Contacts: itamarjp [AT] fedoraproject [DOT] org, kaustubh [DOT] karkare [AT] gmail [DOT] com

Mentor(s): Dennis Gilmore

Notes: webhosting control panel draft

Assemble a toolchain for recording screencasts easily

Status: Proposed - Draft - Need a mentor

Summary of idea: Creating screencasts on Fedora and post-processing them for upload should be easy and fool proof.

The Fedora Videos project has been launched to bring together a collection of screencasts that help people learn how to use Fedora. There's only one major hurdle, though. Capturing really good screencasts on Fedora, post-processing them to include an intro and outro and other effects, and finally exporting them to an open format is challenging. There are lots of different tools, but each one only gets you part of the way there and you have to be the glue to make it all work. And then there are the bugs.

The goal of this project is to assemble a toolchain (a recommended collection of software available in the Fedora repositories) and write a comprehensive tutorial for how to create an professional-looking screencast. That may included chasing down & fixing bugs in the existing tools, discovering new tools and getting them packaged and learning about techniques in the environment around the computer, such as how to select & setup a microphone or how to draft a good speaking script. One possible task in the project is to add sound recording support to the Gnome 3 desktop recorder. Currently, the desktop recorder only grabs the video of the screen.

The student will get support and advice from the Fedora Videos team since they are trying to learn how to create these screencasts.

Knowledge prerequisite: gstreamer, video and sound editing, blender

Skill level: Medium

Improve Fedora's Tablet User Experience

Status: Proposed - Draft

Summary of idea: Improving Fedora's Tablet User Experience.

The window managers/desktop environments officially supported by Fedora do not match the expectations of people with low power touch devices.

Fedora features new technology to reduce system load and - requirements, the user interface has not seen too much love.

Currently available interfaces for users are:

  • Too Ressource Consuming
  • Too Overloaded or
  • Too Feature Poor
  • Not Customizable With Reasonable Effort

The E17 Desktop Shell, developed as part of the Enlightenment Project, is a perfect match. It provides a rich interface, whilst consuming very little ressources. The Enlightenment Foundation Libraries, on which E17 is built upon, were chosen as Foundation Block of Tizen, the MeeGo successor backed by Samsung and Intel. If things work out, E17 will be the first "real" Desktop Shell for Wayland.

Though it already provides special behaviour for touchscreen devices through certain modules, there's still room for improvement.

The overall goal of this project would be to improve the user experience of people who want to use Fedora on low power devices such as tablets.


The student will get support and advice from the Enlightenment Project developers.

Knowledge prerequisite: C, X11, Wayland, Enlightenment Foundation Libraries

Skill level: Medium to High

Contacts: Michael Bouchaud (yoz [at] efl [dot] so), Leif Middelschulte (leif [dot] middelschulte [at] student [dot] kit [dot] edu)

Mentor(s): Michael Bouchaud (yoz [at] efl [dot] so)

Notes: If this idea gets realized, a proper tablet spin can be created, that honors the spirit of Fedora.

Applications for programmers

Implement a binding translator for GlusterFS

Status: Proposed - Draft

Summary of idea: In transporting data across networks, programmers need GlusterFS language bindings to be able to create apps in their language of choice. A language binding translator would greatly increase the number of programmers who would be able to more easily extend GlusterFS. It's also a fun project for someone wanting to get some experience with multi-threaded architecture and design in the context of distributed systems and data.

Knowledge prerequisite: C, Python, embedded Python

Skill level: Medium to High

Notes: -

Implement a Cassandra/NoSQL Connector or Translator for GlusterFS

Status: Proposed - Draft

Summary of idea: In general, there is a need for the ability to store and access NoSQL data on general purpose distributed filesystems. Currently, there are a host of single-purpose methods for storing and retrieving NoSQL data, which are difficult to access from legacy applications. Creating a NoSQL translator for GlusterFS would help mitigate this problem and give developers more options for storing and accessing "big data" in a way that is accessible via a variety of standard toolkits and protocols.

Knowledge prerequisite: C, GlusterFS internals

Linux kernel project

Implement nfs/fscache writeback cache (Dropped)

Status: Dropped -- This is a GSoC _2012_ idea and is being working on by Hongyi Jia although he didn't get the GSoC slot (http://www.jiayi.net/works/nfsfscache-writeback-cache/). So, I'm not going to mentor the idea this year and if anyone is really interested in it, feel free to contact me and I'll be happy to answer questions:-)

Summary of idea: Currently, the flashcache/bcache only works for local filesystems. For network filesystems, nfs only supports write through cache based on fscache/cachefiles. With wider adoption of SSD on nfs client side, it would be great for nfs to support writeback cache to speed up write intensive clients. This project would implement a writeback mechanism for nfs, which need to make necessary changes to kernel nfs, fscache and cachefiles modules, and take care of nfs close-to-open semantics.

Knowledge prerequisite: C, Linux kernel, nfs

Infrastructure for Fedora contributors and users

Design Hub: FLOSS Collaboration for FLOSS Designers

Status: Proposed - Draft

Summary of idea: Free software designers don't have a great set of tools to work with to collaborate with each other and with the community on their design work. With this project, we'd like to make progress towards fixing that. We have some disparate ideas / tools that we'd like to be integrated:

  • Sparkleshare - a git-backed, Dropbox like system that will automatically check in and push files in project directly to a shared git repo
  • Magic Mockup - a coffeescript/javascript you can insert into an SVG of mockups to enable interactive, click-through mockups (see a demo here
  • Design Hub - an idea and a ruby on rails prototype of a web front end that could potentially serve as a front end to git repos with design assets *and* serve as well as a front end to magic mockup mockups in said repos
  • Inkscape is our preferred design tool of choice; it would be great if it had some GUI integration with Magic Mockup, Sparkleshare, and Design Hub

Knowledge prerequisite: Ruby on Rails, web development, some UI design chops Skill level: Intermediate Contacts: edirsh at redhat dot com

Mentor(s): Emily Dirsh

Notes: We can provide a development platform for the web UI at openshift.redhat.com. Also, note this project doesn't just benefit Fedora designers, but it benefits all FLOSS designers.

Implement a unit test framework for fedpkg and rpkg

Status: Proposed

Summary of idea: Unit tests are good. Testing is good. fedpkg and it's backend rpkg is a growing code base, gaining more and more contributors. It lacks a unit test framework which would be very beneficial to the code base for making sure contributions don't break the code in subtle ways.

Notes: This project is in python.

Setup Gitlab as a front end for Fedora Hosted git repositories

Status: Proposed

Summary of idea: To setup Gitlab as a front end for git repositories at [fedorahosted.org].

Git has fundamentally improved the way that developers share code. The barrier to sharing code has virtually been eliminated. We are also seeing the emergence of a new dynamic called "Social Coding". There's no better example of this than Github.

Creating an environment to foster social coding, and a low barrier to sharing code, requires more than just git, though. A lot of what makes Github successful with git is the web-based front end. That explains why there is such a dramatic difference between Github and fedorahosted.org, and why many projects are moving to Github instead.

Fortunately, there is an open source application named Gitlab that provides much of the interactive functionality and usability that is found at Github. The goal of this project is to bring that experience to fedorahosted.org by setting up Gitlab.

This project will require working with the infrastructure team to get the necessary prerequisites installed, find a server to host the application and configure the existing projects to be wired to this interface.

Knowledge prerequisite: Ruby, git, Linux system administration (web servers, authentication)

Skill level: Medium

Contacts: Dan Allen (general), Vít Ondruch (packaging)

Mentor(s): Ranjib Dey (tentative), Seth Vidal (tentative), Dmitriy Zaporozhets (dzaporozhets), Ariejan de Vroom (ariejan)

Notes: This idea is definitely something the Fedora project is interested in pursuing. The work in this project will be carried on after the project, and is an opportunity for a longer-term involvement in Fedora.

See the discussion on the Fedora Infrastructure list about implementation details: http://lists.fedoraproject.org/pipermail/infrastructure/2012-March/011463.html

A demo of Gitlab can be found here: http://demo.gitlabhq.com

Improving Fedora packaging

AUR Clone for Fedora

Status: Proposed - Students' Idea - Need a mentor

Summary of idea: The idea is to make an AUR clone for Fedora where users can submit buildfiles, which need to be hosted. These set of files can compile packages on the user side, and installed locally.

The benefit of this method is:

  1. No need to host the entire packages (saving space on servers hosting the RPMs)
  2. Make changes to the buildfile, and not compile the package
  3. Can pull sources from any version control system/stored tarballs to make a very upto-date package. (See blog entry for an example)

Contacts: Anuj More

Notes: Need mentor. Need advice on feasibility of the software and issues that can arise. Also, read the extensive blog post on my blog.

Analogy: This is a lot like "having your own library" vs "getting a book from a bookstore". If you refer a book often, you'd keep it in your library. This would occupy space and consume resources. Otherwise, you'd just pull out a separate paper with instructions about the bookstore to find the book, and fetch the book from the store. Though the first method is hassle-free, it is not possible to have all the books in the world with you.

Maven FOSS Repository Extension

Status: Proposed

Summary of idea: With the inception of Maven we have a means to standardize the building of Java projects. However it has also resulted in the usage of a very wide dependency set by these Java projects. This makes it very hard to integrate those projects on a single platform (be it Fedora or JBoss Application Server (or the combination)).

In essence during packaging all these dependencies must be lined up to form a single consistent component set. Thus each project will only have those components available which are actually available on the target platform. This is very hard to enforce using standard Maven setup.

For Fedora I'm envisioning a Maven extension that makes sure only sanctioned components are used during the build (without putting a burden on the packager). This will allow developers who are not on Fedora to also build with this extension and thus verify (and fix) issues which are the result of "Fedora packaging".

A prototype can be viewed at Fedora Maven Extension.

Fedora Spins and remixes

Educational Application for Fedora Robotics Suite

Status: Proposed

Summary of Idea: Create an educational app introducing software from Fedora Robotics Suite

The Fedora Robotics SIG is creating a Robotics Suite consisting of many packages useful in robotics. We want to develop a demonstration application introducing new users step by step to core packages like Fawkes and Player/Stage. It would feature multiple game-like levels with increasing complexity. The general task would be to instruct the robot to fulfill a specific task in a simulation environment.


Knowledge prerequisite: Developing this requires a strong background in C++, a background in robotics is preferred but not necessary. You should be able to familiarize yourself with new software quickly. User visible parts will require GUI programming using Gtkmm.

Skill level: Medium to High

Mentor(s): Tim Niemueller

Applications for systems administrators

RHQ-agent to interface with Matahari

Status: Proposed

Summary of idea: Write a RHQ-agent in Python and make it interface with Matahari to pick up metrics that are provided by Matahari from Fedora or RHEL systems. The agent would talk to the RHQ server via the REST api and push metrics to RHQ etc. This agent will not implement the full functionality of the RHQ java agent.

While RHQ is written in Java, this project does not need any Java knowledge.

Knowledge prerequisite: Python, Linux system administration, qpid, principles of REST

Skill level: Medium to High

Contacts: Heiko Rupp <pilhuhn>

Mentor(s): Heiko Rupp <pilhuhn>

Notes: RHQ wiki is at http://rhq-project.org/

Applications for Testers

Fedora Gooey Karma

Status: Proposed

Summary of idea: Fedora Easy Karma is a CLI application to help testers apply karma to installed updates and while it's great at doing so, it doesn't display much other information on what an update is supposed to fix or what can be done to test a particular update. A GUI tool that pulls in more information on packages under test would help in the testing process and hopefully help encourage less techical users to start testing packages.

Knowledge prerequisite: GUI tool kit (Qt or GTK), python

Skill level: intermediate

Contacts: Tim Flink (tflink)

Mentor(s): Tim Flink (tflink)
