Wikimedia Technical Talks

Overview
Technical talks are presentations created by and for members of the Wikimedia technical community. Technical talks cover technical concepts and ideas that make it easier for others to contribute to Wikimedia projects. Formal technical talks are typically broadcast live, recorded and posted publicly for others view.

This page contains information about Wikimedia technical talks and how to view or contribute to them. You will also find links to additional information about setting up and creating technical talks.

Who can give a technical talk?
Short answer: You!

Long answer: Technical talks are open to anyone who wants to share what they know about the technology we use on Wikimedia projects.

Why give a technical talk?
Technical talks are a good way to share information with other people who are working in technical spaces on Wikimedia projects. We all benefit from each other's knowledge, and we all benefit from having different ways to learn.

When you produce a technical talk, you build your skills as a public speaker, story teller, trainer, and teacher. You become more visible to others in the community, and you contribute valuable knowledge to the Wikimedia movement.

Who watches technical talks?
Technical talks are broadcast live and archived for anyone to view in the future. Most people in your audience will be technical contributors just like you.

Wikimedia monthly technical talk
The Wikimedia Foundation currently supports a monthly technical talk with A/V support and hosting for speakers. This talk is generally 45 min in length with a live question and answer session at the end. These talks are broadcast using Google Hangouts On Air, and are immediately available on the MediaWiki Youtube channel. Viewers can ask questions through Youtube or on the #wikimedia-office IRC channel, which is reserved for the talk.

Wikimedia monthly technical talks are announced via email lists and social media. Speakers are encouraged to upload supporting material, including slideshows and videos to Wikimedia Commons following their talk.

Propose a Wikimedia monthly technical talk
Monthly technical talks can be scheduled up to 6 months ahead of time. Learn how to propose a Wikimedia monthly technical talk

Other technical talk opportunities
The Wikimedia monthly technical talk is only one forum for sharing technical information with others. Some potential speakers may want to start with a shorter talk, or they may want to record their own talk or video to share.

Join Youtube stream: TBA

Slides: TBA

Speaker: Evan Promodou and Gilles Dubec

Topic Area: Standards

Description:

The Wikimedia Foundation is now a member of the W3C, as of April. We will walk you through how you can join working groups, what to expect of W3C participation, what we hope Wikimedia staff can achieve through W3C and we will share our own experiences as W3C members.

Episode 3: Sharing global opportunities for new developers in the Wikipedia community
April 24, 2019 at 18:00 UTC, 45 Min

Join Youtube stream: https://www.youtube.com/watch?v=SXyeRujCrAs

Slides: https://upload.wikimedia.org/wikipedia/commons/3/37/Slides_from_Wikipedia_session_at_LibrePlanet_2019.pdf

Speaker: Srishti Sethi, Developer Advocate, Wikimedia Foundation

Topic Area: Developer Advocacy, onboarding new technical contributors

Description:

Wikimedia offers a plethora of opportunities for newcomers to get involved; however, as with many other free software projects, getting involved with the Wikimedia technical community can be a daunting prospect for newcomers. This talk is a gentle introduction to the Wikimedia ecosystem, and gives pointers on how to get involved as a volunteer. I will delve into the various ways newcomers can make successful contributions in areas ranging from design to documentation, from programming to testing, and much more.

Episode 2: Ouch, I have an OOUI: using OOUI without pain

 * March 27 2019 at 18:00 UTC, 45 Min
 * Join Google Hangout Meet Live: https://www.youtube.com/watch?v=T_CUN2o4faw
 * Slides: TBA
 * Speaker: Moriel Shottlender
 * Topic area: OOUI
 * Description: OOUI is the interface widget library we are using for UI in the Wikimedia projects. The library is meant to allow implementers to create useful interfaces that automatically answer internationalized needs that are unique to the global nature of our projects. Right-to-left support, supporting old browsers, accessibility, etc, are things that OOUI is doing in the background for you.This tech talk will present OOUI’s history, basic and advanced usage, and demonstrate how to create great interfaces without (much) pain within our wiki ecosystem.

Episode 1: The long and winding road to making Parsoid the default mediaWiki parser

 * February 27 2019 at 19:00 UTC, 45 Min
 * Video: https://www.youtube.com/watch?v=lQGfuLP9MqA
 * Slides: https://commons.wikimedia.org/wiki/File:The_Long_And_Winding_Road_To_Making_Parsoid_The_Default_MediaWiki_Parser.pdf
 * Speaker: Subbu Sastry, Principal Software Engineer
 * Topic area: Parsoid, Wikitext Parsing
 * Description:
 * This will be a talk in two parts: The first part will provide a bunch of background to make sense of the roadmap presented in part 2. The second part will have 3 components: (a) Parsoid history (b) Porting Parsoid to PHP: the whys and wherefores (c) From here to Parsoid as the default.
 * Parsoid started in 2012 as a project to support Visual Editing and since then has gone on to support a number of products (Flow, Content Translation, Kiwix, and Android app). Given that (a) Parsoid's annotated HTML output enables clients to infer things about wikitext without having to parse wikitext, (b) the PHP parser cannot support Visual Editor and other products, and (c) we cannot continue to have two parsers, it is inevitable that Parsoid will be the default parser for MediaWiki. This has been known since at least 2015 but while we are nearer to that goalpost, we are still not quite there yet.
 * In this talk, we'll talk about what else needs to be completed, and what the porting of Parsoid to PHP means for this goal.
