Google Code-in/2013

Google Code-In is a contest to introduce pre-university students (ages 13-17) to the many kinds of contributions that make open source software development possible. Students must complete tasks (see examples), one at a time. The Google Code-in 2013 contest runs from November 18, 2013 to January 6, 2014.
 * 2013-11-01: Mentoring Organizations for Google Code-in 2013 are announced (Google's announcement)
 * 2013-11-01: Wikitech-l: Google Code-in: YES, WE ARE IN! (our community annoucement)

Tasks
This selection shows the variety of tasks available. The descriptions of the tasks are not final, and we are still polishing them. We can generate more tasks for most categories. As a reference, currently we have identified about 240 annoying little bugs.

Code
Tasks related to writing or refactoring code.

Matma Rex (talk) 15:55, 18 October 2013 (UTC)
 * [ & ] Interwiki tooltip shouldn't start with a dash on the main pages; interwiki tooltip: " should not be double-escaped. Explanation for each in bug comments; they're both simple fixes in the same area of code, so sticking them together. Matma Rex (talk) 18:34, 18 October 2013 (UTC)

 * Create and document an API so external tools may a) provide a list of images asynchronously b) add jQuery-Objects or DOM-Elements to the caption/info-container (e.g a button for votes). Rillke (talk) 14:11, 2 November 2013 (UTC)
 * Apply MediaWiki's coding-style to Common's Stockphotot gadget, outsource style (maybe create a sprite for all the images), make it modular: Input: HTML-string; Output: An object containing all the links -- this allows us to re-use this gadget inside other tools. Rillke (talk) 14:17, 2 November 2013 (UTC)
 * Media uploads via websockets as HTTP multipart/form-data submission streaming to avoid firewalls.

Quality Assurance
Tasks related to testing and ensuring code is of high quality.


 * [] Triage (test) any 10 of the Vector skin (default) issues tracked on . [There are currently 38 open sub-bugs, so this could be split in up to 4 tasks.] Matma Rex (talk) 15:55, 18 October 2013 (UTC)
 * First part: Read and understand Bug_management/Bug_report_life_cycle. Then edit the embedded file Bug_Life_Cycle_Diagram.svg with a Vector graphics application (e.g. Inkscape) and update the file (also the PNG version) to also include the recently introduced "PATCH_TO_REVIEW" status which only comes before "RESOLVED FIXED" (but none of the other resolutions). This needs graphic skills how to present information in a non-confusing way. Second part: Follow the steps on How_to_report_a_bug and check if they are all still correct in the new "guided bug entry form" which can be tested on . --AKlapper (WMF) (talk) 16:04, 22 October 2013 (UTC)

User Interface
Tasks related to user experience research or user interface design and interaction.


 * [] Fix any 3 of issues reported with interface translation messages needing rewording or documentation tracked on . [There are currently 78 open sub-bugs, so even if not all fit this we have basically infinite supply. Some of them are more complicated, though… a quick triage might be needed.] Matma Rex (talk) 18:14, 18 October 2013 (UTC)


 * Make MediaWiki High-density display friendly. Bugs from [], some selected below:
 * [] Vector: Add SVG version of magnifying-glass icon. It would have to be redrawn as an SVG image (it's pretty simple) and added to our LESS styles with the background-image-svg mixin (like, for example, arrow-down-icon.svg). Matma Rex (talk) 19:36, 18 October 2013 (UTC)

 * [] RSS/Atom feed icon for sidebar is low-resolution. Find and integrate an SVG version. Pginer (talk) 11:26, 22 October 2013 (UTC)

Mentors' corner
First things first:
 * 1) Become an official mentor in Google's Melange.
 * 2) Continue listing polishing tasks in this wiki page. Only org admins can post them in Melange...
 * 3) Watch this page for more instructions, or ask for them.
 * 4) Be ready to learn with the rest of us along the way.  :)

Become a Wikimedia GCI mentor
Register as mentor. If you have technical problems send your GCI username to Quim.

Requirements of a task
All the tasks listed here must be also listed in Melange well before November 17, since that is the interface that students will use. We can discuss the details e.g. having a basic boilerplate task description pointing to bug reports with all the details.

Mentors can add tasks at any time, also after GCI has started. Usually this is what happens when students are finishing tasks, they have already learned about a specific area, and they want more tasks related to it.
 * Tasks are supposed to take 2-3 hours to an experienced contributor. It is fine if the first task takes even 2-3 days to a student because they must understand many concepts and setup their environment first. And it is also ok if students specialize in a type of task, so every new task takes less time to complete until they are also able to complete them in a couple of hours.
 * Tasks are self-contained. Students must be able to complete it without much knowledge of the context, or the background.
 * By default, tasks are described in a bug report with the keyword "easy" and 1-2 mentors CCed and volunteering explicitly in the comments.

A list of potential candidate bugs is available as the GCI candidate bugs saved search on Bugzilla (MediaWiki and extensions, +easy, -gci2013, no patches pending).

Candidate bugs should have " gci2013 https://www.mediawiki.org/wiki/Google_Code-In#Candidate_tasks " added to their Whiteboard field to make it easy to track them.

Org admins Quim Gil and Andre Klapper go through proposed tasks and confirm them. CC us in the bug reports.
