Other projects

[edit]

Special mention should be made of two projects that were not done via the Wikimedia Foundation, but are still relevant to Wikimedia sites. The first was a GSoC project done with CiviCRM, instead of the WMF, as a mentoring organization. The student was Saurabh Batra, and the mentors were Adam Wight and Eileen McNaughton. Saurabh created a fraud-detection API for Wikimedia donations that could potentially save the WMF tens of thousands of dollars in the form of chargeback payments. See the main API code, sample pipeline code that calls the API, and the student's project summary.

The second project was done unsupervised and not as part of GSoC, though it was completed concurrently with GSoC. The student, Balaji Ramasubramanian, developed a Facebook chat bot for Wikipedia that users can subscribe to, to receive notifications for Article of the day, Picture of the day, Random article, Top read, etc. from Wikipedia. See a video of the bot in action, as well as the project task and code commits.

"Turning MediaWiki into an efficient localization platform" - improvements to the Translate extension.

See Nikerabbit's GSoC 2009 wrapup blog post.

  • Student: Niklas Laxström (Nikerabbit)
  • Mentor: Siebrand Mazeland
  • Outcome: In active use on translatewiki.net and dozens other wikis. Niklas Laxström was active in the community before and after this project, and currently works for the Wikimedia Foundation.

Image rendering daemon

[edit]

Was written in Python and designed to handle asynchronous image rendering requests.

"This is a proposal to fix the MediaWiki bug #4854, implementing a daemon program to render and resize images uploaded by Wikipedia users. Separating the image manipulating work from the MediaWiki application will greatly alleviate application server's load, thus improve the overall performance. The API will be designed as general as possible to accommodate the needs of other applications that also render and resize images in large quantity."
  • Student: Zhe Wu
  • Mentor: Aryeh Gregor (Simetrical)
  • Notes: Proposal was very well written, programmer obviously knew what he was doing. Major issues:
    • Was being developed on another repository. Should have been in SVN with everything else.
    • Mentored by an accomplished developer, but someone who had little interest in the subject matter
    • While the proposal was very well written, it wasn't developed with Wikimedia operations in mind. Their wants/needs should've been solicited and probably consulted during the process as well.
  • Outcome: Final status email. Since it was developed off-site, it never really received much input. It appears that none of the code was ever looked at by anyone in operations for potential deployment on WMF.

2008

[edit]

WebDAV

[edit]

"I am working on an extension which provides a WebDAV / DeltaV / Subversion interface to MediaWiki articles: WebDAV"

"The extension enables articles to be browsed and edited with WebDAV or Subversion clients. When complete, it will support editing articles offline, using for example the Subclipse Eclipse IDE plugin or Emacs VC mode."

  • Student: Jack Bates
  • Mentor: ?
  • Outcome: The WebDAV extension became unmaintained soon after its creation, but was then resurrected in 2019.

Visual Diff

[edit]

Visual diffs/2008 project - A system to provide more visually intuitive diffs, rather than lines added/removed.

  • Student: Guy Van den Broeck
  • Mentor: Brion Vibber
  • Notes: Brion was always busy, so Guy asked a lot of questions in #mediawiki.
  • Outcome: Had lots of outstanding issues - i18n, style, etc. Was a part of two releases, 1.14 and 1.15, in which it was disabled by default. Removed from trunk in r58267, and was not in 1.16 or subsequent releases. The code was used, however, as the basis for htmldiff, a non-MediaWiki PHP library that displays diffs of HTML snippets.



Special mention should also be made of another MediaWiki-related project done in 2008, but by Creative Commons and not the Wikimedia Foundation: a project to add RDFa support to Semantic MediaWiki. David McCabe was the student and Nathan Kinkade was the mentor. The code created is no longer in use.

Audio/video file recoding

[edit]

The proposal: "Audio and video can instruct and inform in ways unattainable by words and still images. Currently, audio and video have only limited support and are often cumbersome to access in MediaWiki and the various projects of the Wikimedia Foundation. This project seeks to allow Wikimedia's sites to more effectively leverage the power of audio and video resources. To achieve this, a reliable and expandable system is proposed to automatically recode contributions from numerous digital a/v formats to a single, royalty and patent free compression standard. With the ability to generate such a library, Wikimedia would be poised to easily present a vast range of audio and video to their visitors using an in-browser streaming player."

  • Student: Mike Baynton
  • Mentor: Brion Vibber
  • Outcome: Code appears to have been unused by the WMF.

2006

[edit]

LiquidThreads

[edit]

"Add support for structured discussion pages. Option for discussion pages to be more like message boards with threads. Current discussion format is less than ideal (can modify others' comments, cluttered editing window, etc). This could also include support for embedding polls in discussion pages, voting on proposals, etc. Basically, create a minimal message board system that is tailored for use in a wiki environment (see LiquidThreads [this is a link to the page as it existed then] for some ideas in that direction)."

  • Student: David McCabe
  • Mentor: Erik Möller (?)
  • Outcome: This project created the first version of the LiquidThreads extension. David was temporarily re-hired by the WMF in 2008 to maintain and improve the extension. LiquidThreads was almost entirely rewritten (by Andrew Garrett) in 2010, before being abandoned in 2013.

Video display

[edit]

No-install, in-browser display of video (and audio?) clips for Wikimedia Commons, using reasonably common Java and/or Flash components. Needs to be able to 1) play or transparently pre-convert Ogg Theora videos, 2) avoid use of patent-encumbered formats. Consider integration of Fluendo's Cortado player applet as a starting point.

Brion's talk suggested that this project would also involve creating thumbnails for video clips.

  • Student: Michael Dale
  • Mentor: Brion Vibber
  • Outcome: Michael Dale went on to work on other MediaWiki video efforts (metavid, which eventually turned into mwEmbed and finally into TimedMediaHandler, which is in testing and review before WMF deployment). Tim Starling did the final integration of the Cortado applet and Ogg parsing as part of the OggHandler extension, which currently supports video functionality on Wikimedia Commons. Michael Dale came back to work with the Foundation in late 2008 on a few different projects with support from Kaltura, mentored a student in 2009, and is still active in developing Wikimedia technologies.
