Community:SummerOfCode13

This page lists all the Google Summer of Code 2013 projects with confirmed mentors, and which have been approved by the SoC administrator. New suggestions can be made on the Brainstorming page. This page is locked; contact Gerv with edits.

Potential students: you may choose from the list below, but you do not have to. Feel free to submit a proposal for your own idea. However, before you do so, see the guidelines for good ideas. You can also discuss your ideas or application in the #developers channel on IRC: irc://irc.mozilla.org/#developers . Your idea will have a significantly greater chance of being chosen if you can find an existing member of the Mozilla community who is willing to evaluate or mentor it. (You should name that person in your application.)

In addition to the specifically-named projects below, we have also tagged a number of bugs in Bugzilla with the keyword student-project. However, as the idea of a "student project" is wider than just the Summer of Code, students looking through the list will need to decide whether any particular bug listed there is actually the right size and scope for Summer of Code.

Application Advice

Note that if a project suggests it would be helpful to know XUL (Mozilla's user interface description language), you may be able to get away with learning on the job. Don't be put off from applying if the project otherwise looks right for you.

• Read the GSoC Student Guide and follow its advice.
• Read How Not To Apply For Summer Of Code and avoid doing the things listed there.
• Read our examples of good applications: 1, 2, 3.
• Apply on the GSoC site (note that we have an application template).
• It is entirely acceptable to apply for 2 or 3 projects, if more than one catches your eye; if the applications are high quality, that probably improves your chances a little. However, more than 3 seems like spam.

Questions of any sort? Send mail to Gerv and Florian. We will try and respond as soon as possible and get your questions directed to the right person. Please allow at least 48 hours for a reply. If you want to contact a mentor and contact details are not here, ask people in the #developers channel on IRC: irc://irc.mozilla.org/#developers.

Firefox

Title	Details	Skills Needed	Reporter	Mentor(s)	Comments
Silverfox	Silverfox is the codename of a new feature meant to be an operation mode targeted to beginner users who are being guided on learning how to use the web. In this mode, most settings should be locked down, preventing the user from mistakenly tweaking settings or installing unwanted add-ons. It's not meant to be a tightly controlled, irreversible-without-password setting, but rather a feature that will make it harder to accidentally break or deteriorate the Firefox experience. This project will be implemented using the Add-on SDK.	Good JS skills and ability to work with large codebases. Previous add-on experience is a big plus.	Felipe, Jared	Felipe, Jared (felipe, jaws on IRC)
about:memory For Real People	about:memory has been a very useful tool for us developers to better understand memory consumption in Firefox and help diagnose and fix problems (See the MemShrink project). We would like to make about:memory also useful for web developers and users by providing better data visualization and analysis that will help them understand the footprint of their websites and improve accordingly. You should be able to come up with useful and creative ways to visualize that data and implement those visualization using JS. We would still keep the original about:memory but relabel it as something like "Stats for nerds". It is important to keep the original/light-weight version since a visual-heavy implementation of about:memory will use non-trivial amounts of memory.	Good JS skills and knowledge/passion for data vizualization. Past work with data visualization is a big plus.	Felipe, Jared	Felipe, Jared (felipe, jaws on IRC)
Fullscreen Mode	One upcoming Firefox feature is a fullscreen mode that should provide an immersive experience. This mode will provide a streamlined interface as can be seen in this preliminary mockup. Features such as a clock and other OS indicators (new APIs have been implemented for these from the WebAPI project) might also be part of the project. The implementation of this feature will mostly involve three languages: XUL, CSS and JS.	Great CSS skills are important, and knowledge of XUL/flexbox is a plus. Good JS skills. Past theme development experience would be great.	Felipe, Jared	Felipe, Jared (felipe, jaws on IRC)
Enhanced Customization APIs	Firefox stores most of its configuration using the Preferences system, which uses a plain text file in the user's profile folder to keep its name / value pairs. Certain add-ons have traditionally changed settings like the homepage and search engine by editing this file directly or using the preferences service incorrectly, and fail to revert the settings, causing much user annoyance. With the Enhanced Customization APIs project we want to change this, by moving these critical settings to a different system where the only accepted interaction is through an API that knows when to revert these changes. Storage would most likely be sqlite, so that it isn't trivial to edit from external installers.	JavaScript and C/C++ required. Some add-on development experience is desirable.	jorgev	jorgev / Kris Maglione
Clearer Add-on Installation	There's a mixed bag of features we want to implement in order to improve add-on installation. The ones we want to include in this proposal are the following: (1) Redesign external install opt-in screen (bug 834385, (2) The opt-in screen needs to support multiple add-on installs, (3) Make it possible to completely remove globally installed add-ons from the Add-ons Manager (disable and hide), (4) Make it possible to request add-on install / uninstall from a separate process. All of these mostly concern add-ons being installed by external installers. We want to improve the opt-in screen that shows up when they are installed that way, and other issues that will make it easier to users to control their experience. This is a group of small changes rather than a single big one, so a student would need to work closely with the mentor to direct their time appropriately.	JavaScript required. Some C/C++ might be needed as well.	jorgev	jorgev / Kris Maglione
Autosuggest Search Engines	Many websites have search fields that are used many times over, but these websites do not present themselves as search-capable in order to offer itself to be added as a search engine in the browser. Firefox should detect repeated search field usage and offer that as an option to the user. At a minimum, it should be able to detect it and add an entry with "Add [website]" in the searchbar dropdown (similar to how OpenSearch works). After the detection part is working well, a refined UX for the feature can be discussed and prototyped (but that shouldn't be the focus of the project). The student should be able to propose methods on how the detection algorithm should work and how to make improvements on it over the course of the project.	Great JS skills and understanding of DOM, HTML form fields, and algorithms (db and data structures that will be used to store and search the input field history to detect patterns of search usage)	Felipe	Felipe (felipe on IRC), MattN

Thunderbird

Title	Details	Skills Needed	Reporter	Mentor(s)	Comments
Thunderbird Tests	Thunderbird's test coverage is not as complete as it could be. This task is to write tests, where they are missing, for Thunderbird features. We also have some contributors writing patches that were rejected because the contributor was not also able to produce a test for the feature (which can be much harder than just producing the feature/fix). So the task would also involve the student picking up and helping with these patches. Example bugs: bug 580349, bug 379831, bug 253830. It would be a great opportunity to get to know several different areas of the Thunderbird codebase.	Javascript required. Experience with mozmill or xpcshell test infrastructure an advantage.	aceman	mconley
Backend Connectors for 'Ensemble'	mconley is writing a new address book for Thunderbird. This should be stable enough by the summer so that it is possible to write new connectors to connect to various contact storage backends. We will only be targeting read-only support this summer - writing contacts back will come later. Possible backends include: system address book on any platform, LDAP, CardDAV servers, and Google Contacts. The connector API is specified here, but may evolve during the project. Applicants should specify which backend they're interested in implementing, and should be highly proficient in Javascript. C/C++ is a bonus, but not entirely necessary. Previous experience working with their chosen backend is highly desirable. Thorough tests for the new connector will be expected.	JS, although some C/C++ for native may be necessary	jcranmer	mconley
Mailbox-to-Maildir Converter	Mailbox and Maildir are two alternative on-disk storage formats for email messages. Thunderbird currently uses Mailbox, but wants to use Maildir. Hence the need for a converter. This is one of the last critical pieces blocking moving away from mbox-style mailboxes.	C++, although some JS may be necessary	jcranmer	jcranmer

Bugzilla

Fix Code Review on BMO	The current Splinter extension which provides code review capabilities on bugzilla.mozilla.org (BMO) can be updated quite a bit. We want to pave the way toward integration with CodeReview.js from the Webkit project. Specifically, we want to integrate the Splinter review functionality with the PatchReview Perl module and experiment with integrating that with the CodeReview.js tool.

Web Audio Compatibility Project	The Web Audio API is landing fully-formed and spec-compliant in Firefox 22, however most of the code in the wild was written when this API landed and have not been updated to the version of the spec that Firefox supports. This project would target any and all open source libraries, games and applications that use Web Audio API and ensure that they work properly with Firefox's implementation.	Some expertise in JavaScript, Web Audio, Git/Github, blogging and being polite.	Jeff Griffiths	Jeff Griffiths / Ehsan Akhgari

Automation & Tools

Title	Details	Skills Needed	Reporter	Mentor(s)	Comments
Unit Tests for Mozbase	Mozbase is a set of low level Python classes that all of Mozilla's automated test harnesses will soon be refactored to use. As we gradually move through the process of converting all our test harnesses to use Mozbase, we want to ensure that all our harness modules have explicit unit tests for their targeted use cases - i.e. tests for the test harness :-). We will work with interested volunteers to define a set of test cases that need to be added, and work with them to add those cases.	Python, JavaScript	Clint Talbert (IRC: ctalbert)	Clint Talbert (IRC: ctalbert)
Improve Usefulness and Ergonomics of Peptest	Peptest is a test framework that was written to test the responsiveness of Firefox. In it's current state it is more of a proof of concept that still needs to be fleshed out with all the bells and whistles that will make it truly useful to developers. Some tasks include integration with the built-in profiler, using Marionette as a back-end to drive tests (will also make it easier to run peptests on mobile platforms), improvements to the API exposed to test authors, multitude of other minor tweaks that help make the Peptest experience as painless as possible.

MDN CSS Generation Tools	The task is to create 6 visual and interactive tools to be added into the Mozilla Developer Network website that allow people to generate CSS with complex effects in an easy way. Some examples of CSS features which would benefit from such a tool: gradients (linear and radius), border-radius, border-image, color picker, &-code finder, ... Example of such tool (rough): https://developer.mozilla.org/en-US/docs/CSS/Tools/Cubic_Bezier_Generator	You need to know about JS (good), CSS (basic), HTML (basic)	Jean-Yves Perrier	Jean-Yves Perrier	In your application, you should list the tools you would create. You should submit 8 tool ideas, and the ones you will actually do will be agreed at the beginning of the project. Success will be measured if 6 of these tools are implemented, reviewed and live in the MDN.

Rust

Title	Details	Skills Needed	Reporter	Mentor(s)	Comments
Rust Debug Symbol Generation	Rust is a new compiled programming language that Mozilla is working on. At the moment, Rust programs are tricky to debug when they don't work because they lack debugging symbols. This work has been started, but for many core Rust features the current debugging support is little to none. The goal of this project would be to support building the self-hosted (i.e. written in Rust) compiler with full debugging symbols enabled, and fill out the suite of automated gdb tests to ensure that the debugging support does not regress in the future. The project will require making use of LLVM's source-level debugging features and building on the debugging support that already exists in the compiler.	Rust, LLVM experience beneficial	Josh Matthews (jdm)	Josh Matthews (jdm)	Practical experience with Rust is rare. Therefore, any student interested in this project should take some time to become familiar with Rust so that the actual project time is spent on practical work instead of learning the language.

Add-on SDK

Title	Details	Skills Needed	Reporter	Mentor(s)	Comments
NPM Support for SDK	The add-on SDK (previously known as Jetpack) has no good story for dependency management. It would be great if SDK users could use npm - the Node Packaged Modules system from node.js - for publishing and installing reusable SDK modules.	Javascript, NodeJS	gozala	gozala

Foundation

Title	Details	Skills Needed	Reporter	Mentor(s)	Comments
Notebook Playback	The aim of this project is to add record-and-playback to the IPython Notebook - an interactive Python development environment - using popcorn.js (or its successor) so that people can create "screencasts" that are actually first-class content replayed in the browser. Based on discussion with the IPyNB team and Bobby Richter, we believe this can be done as a Javascript plugin to IPyNB v. 0.14 or higher by embedding timing metadata in the notebook's JSON file. The project would require substantial UI design and evaluation as well as Javascript hacking. The result would immediately be used by Software Carpentry and other projects for teaching, sharing code examples, etc.	JavaScript, User experience design	gvwilson	gvwilson
Meemoo Media Server	Meemoo is a framework for connecting open-source modules, powered by any web technology - "hackable web apps". This task is to design a method to record audio and video locally, using WebRTC streaming to a local Node.js server. Saving images could also be a good goal. It should be easy to save media and then bring it back into the Meemoo app.	JavaScript, WebRTC, Node.js	Forrest Oliphant	Forrest Oliphant
Hacktivity design	http://meemoo.org/ is browser-based data flow coding environment. The goal is to bring more people, including children, to the world of open source creative coding with instantly-hackable creative apps that run in the browser. "Hacktivies" are activities that encourage playful exploration with images and code. For this project, you should prototype and design ways to bridge the digital/analog high/low tech code/craft divide. http://meemoo.org/hack-our-apps/ for some examples. A successful proposal will include some creative output made with Meemoo to show understanding of the system.	JavaScript, craft, activity design, graphic design, writing		Forrest Oliphant, in relation to the meemoo.org project.

Instantbird

Title	Details	Skills Needed	Reporter	Mentor(s)	Comments
FileLinks in Instant Messages	Goal: File transfers that work reliably for every protocol. Description: The Thunderbird Filelink feature allows users to upload attachments to an online storage service, replacing the email attachment with a link. This existing code could be used to implement file transfer. While some protocols support file transfer directly, this approach would provide a fallback that should always work. Designing and implementing a good UI frontend would also be required.	JavaScript, XPCOM, XUL	Florian Quèze	Florian Quèze	The frontend should be flexible enough to be able to handle other file transfer methods when they are implemented, e.g. WebRTC for XMPP or DCC for IRC.
Additional JavaScript Protocol Plug-ins	Goal: Implement new protocol plug-ins in JavaScript, or create more stable implementations of existing ones. Description: Instantbird supports protocol plugins implemented in JavaScript, in addition to the C libpurple plugins. The student will either add support for new protocols in Instantbird (if so, explain why this protocol matters) or reimplement in JavaScript a protocol that is poorly supported by libpurple (if so, explain what will be better supported in the new implementation, or why the current implementation is not adequate). All new protocol plugins will go through a strict code review to ensure high code quality. The student working on new protocols should take every opportunity to improve the code and APIs shared by all JS protocol plugins. Please name the protocol or protocols to be worked on in your application.	JavaScript, XPCOM, maybe js-ctypes	Patrick Cloke	Florian Quèze for JS-SIP, Patrick Cloke for other protocols	IRC, XMPP, Twitter and OSCAR (AIM/ICQ) have been (or are in the process of being) implemented and should not be considered.
Improve JS-XMPP	Goal: Ease working with the JavaScript XMPP implementation and implement new features. Description: Include better syntax for XML handling, implementing handling of MUCs and other features. Feature-parity with libpurple's XMPP support is one of the prerequisites for replacing the libpurple XMPP plug-in that is currently used. One possible improvement would be to support voice and video calls between a JS-XMPP client and a Jingle client using WebRTC.	JavaScript, maybe XUL, XPCOM	Florian Quèze	Florian Quèze
Skype Protocol Plug-in	Goal: Support Skype chat features as protocol plug-in. Description: Microsoft will soon dropping support for MSN/WLM, they suggest that all users migrate to Skype. The student is expected to implement support for Skype chat (private messages and multi-user chats) using the SkypeKit SDK. This project does not need to support voice/video chat to be considered a success. Access to SkypeKit can be provided to a student participating in this project. This may need to be implemented as an extension.	C++, XPCOM	Patrick Cloke	Patrick Cloke
"Awesometab"	Goal: Create a tab that "knows" what conversation you want to open (like the "awesomebar"). Description: The current "Join Chat" dialog is ugly and difficult to use. A user should be able to open a new tab to create a new conversation which will auto-complete fields based on history and server information (e.g. LIST from IRC).	JavaScript, XPCOM, XUL, maybe some protocol interactions?	Florian Quèze	Florian Quèze, aleth

Security Engineering

Title	Details	Skills Needed	Reporter	Mentor(s)	Comments
Project Janus	Build a Firefox addon that emulates dynamic profile switching, like Chrome supports signing in as multiple profiles. The actual profile-switching code is out of scope of a GSoC project, but writing a visual stub that users can interact with would give us valuable information as to what kind of support (real multiple profiles, Guest Mode, Private Mode) are most useful to people. The addon would need to collect metrics, e.g. how often to people switch profiles, how many profiles does an average user need, how many sites to people access across multiple profiles. Building a Chrome extension to collect the same metrics would also be very useful.
