Zürich Hackathon 2014/Topics

Add a topic you want to work on at the next Wikimedia Hackathon!

Template:

Galleries for topic pages
Create the concept of a gallery for any type of topic page (Article, User, Wiktionary, Wikivoyage) where a user can search and contribute images from commons.

Interested persons:
 * 1) (add yourself)

= Sprints =

Regular contributors plus some newcomers hack together with a shared goal.

Recommendation engines
A lot of regular users end up reading one article on Wikipedia (through Google Search) and other articles which they need as pre-requisites. It would be interesting to have a recommendation engine for Wikipedia, Wikiquotes and Wikisource.

Production-like Vagrant
Our goal is to make a handful of high-priority puppet roles available to MediaWiki-Vagrant to make developer instances of Vagrant closer to a production-like environment. The ultimate idea is to provide a uniform developer-focussed instance to Mediawiki engineers to facilitate better testing of new and existing code, while also making it easy for new engineers to get started hacking on Mediawiki and Mediawiki with minimal friction for bringing new features to production. The first hurdle will be to provide some crucial production services in MediaWiki-Vagrant, which will be our focus for the Hackathon. Possible services to focus on include
 * Varnish
 * SSL
 * MariaDB
 * Memcache/Redis
 * CentralAuth
 * Possibly multiversion support?
 * configure MW and set of apps in a way to mimic production but for performance tweaks (cf https://gerrit.wikimedia.org/r/#/c/119216/)
 * Prepared XML dump import

Maps integration
The idea is to bring pin map templates, geohack, wikiminiatlas, openstreetmap, Extension:Maps, Special:NearBy, mobile, coordinates extension etc etc etc, more together in a way that works for mobile, desktop, micro and macro contributions. It would be handy if before hand we can do some exploratory work to create a more focused effort during the hackathon: Zürich Hackathon 2014/Geo Namespace.

Wikimaps project
There are topics for meetings/sprints with a wider developer/designer/GLAM advocate community with the Wikimaps project. We are hoping to set up a corner for continuous workshopping and an event for kick-off discussions in quite the beginning of the event.
 * Template:Map for archival metadata, geolocation and temporal properties of maps. For inclusion in the GWToolset.
 * 1) Susanna Ånäs and André Costa (WMSE).
 * Map gadget: Apply the map template to a map image in Commons with a gadget.
 * If your skills apply, please volunteer!
 * I wont be making it to the hackathon for visa issues, would love to volunteer though. Jeph Paul


 * Map upload wizard: Apply the map template to an uploaded image (or any other template).
 * Can we get support from WMF for this?


 * Spatiotemporal gazetteer: How to model change of a place over time in Wikidata? What are limits of notability or granularity?
 * Discussion


 * Linking OHM/OSM to Wikidata: Where to store which data? What technologies are used? What are licensing issues?
 * Discussion (see also new Wikidata property OSM tag or key)


 * Dreaming the maps interfaces: How to roughly place an old map in coordinates? How to search for maps? How would you use maps?
 * Paper prototypes and heated debates in the Maps corner


 * Practical: Testing, gathering comments, documenting, learning: commons:Commons:Wikimaps, http://warper.wmflabs.org/

Historical Maps of Zurich on the open data portal of Zurich
It is possible to get the Maps of the open government data portal under CC0: Example of Stadtplan of 1793 Maybe it would be a good task to "milk" that map and store the maps in Commons. --Micha 11:18, 2 April 2014 (UTC)

Moving from Toolserver to Labs
--Kolossos 18:09, 24 April 2014 (UTC)
 * Reactivate the community we had on maps-l and Toolserver, bring new into the game
 * Optimize render stack, tools and frontends
 * Updating styles, create new styles
 * Playing with PostGIS (we have OSM data, WIWOSM and Wikipedia-coordinates there)
 * Talking about new ideas and priorities
 * I would be glad to give people introductions for first steps in GIS

Geocoding with Wikidata
--Kolossos 18:09, 24 April 2014 (UTC)
 * using classes in Wikidata as a better way than the existing object types in Wikipedia-Geocoding.
 * Connecting Wikidata with OSM, e.g. OSM-Tagging
 * Creating tools to help the community (only 30% of all geo-objects are member in a class).

Future of Wikimedia-Maps
--Kolossos 19:29, 7 May 2014 (UTC)
 * What we expect from the Maps & Geo Team?
 * Where should be the priorities?
 * How will maps in Wikimedia-projects looks in future?
 * What can we do as community?

Snuggle l10n & OAuth sprint
Snuggle (en:WP:Snuggle) is a late (at least not the earliest) adopter of OAuth and that's a shame. There's also requests to extend support to Portuguese and Italian Wikipedias. In this sprint we'll discuss & design UI changes to support an OAuth handshake with MediaWiki. In parallel, we'll also be extending Snuggle's configuration to support IT and PT wikis. Italian and Portuguese Wikipedians needed to help with localization.

Interested persons:
 * 1) Halfak (WMF)
 * 2) Nemo As requested by Gianfranco. :) Will try to get some other Italian join too.
 * 3) (add yourself)

Experts meet novices to share knowledge in hands-on tasks.

Integration of Open Government Data in Wikidata and other Wikimedia projects
There are a lot of open government data evolving with interesting data which can be used for wikimedia projects. For example: The data of polls and referendums, the population of cities and municipalities, the public art in cities (interesting for Wiki Loves Public Art). How can the data of that portals be transfered automatically to the wikimedia projects. For example generating a script on the tool server which checks daily if some numbers have changed. If yes, it transfers the data to wikidata and from there the data is included in the infoboxes of the Wikipedia articles. Or how can the list of public arts or of other objects (ex. fountains) in wikipedia be updated automatically if there is a new object or an object has been removed.

As a concrete task we will promote the integration of demographic data from the open data platform to wikidata for integrating the data in the specific articles of the districts. Ex. in the german article of the Rathaus District.

The RACHEL Project
RACHEL (www.rachel.worldpossible.org) is now reaching over one million users worldwide who lack access to reliable internet. The project was a weekend prototype by just a few Cisco employees years ago. Please consider lending your web development, perl skills (dev.worldposible.org), or linux ideas to help us enhance this fantastic product (as seen on BBC, CNN, RaspberryPi.org and much more). Currently, foreign language wikipedia inclusion requires running a second webserver dedicated to wikipedia, an inefficient use of resources in places where these are scarce. Help us integrate foreign language wikipedia without running a second server (biblioteca.worldpossible.org).

Clean Code
Full title: Clean Code, and other requirements for contributing to Wikibase

This is an introduction to the topic of clean code. It covers basic design principles, effective use of tests, and many general best practices. Want to know how to write code that is easier to maintain? Want to avoid spending so much time in the debugger? Want to write code that reads like well written prose? Want to become more effective at the craft of software development? Then this session is definitely for you.

This introduction is broad and covers a lot of ground. While many topics will not be covered in the depth they deserve, references to other material will be provided. The focus on the most common problem points and practical solutions.

A lot of the topics that will be covered are part of the contribution guidelines for the Wikibase software. Examples from Wikibase will also be used in places, though this session is by no means Wikibase specific.

Flow for bot and tool developers
Flow is a modern discussion and collaboration system for WMF wikis. However, Flow pages aren't talk pages, so bots and semi-automated editing tools (e.g., Huggle, Twinkle) will have to adapt to handle them.

MediaWiki-Vagrant Bootcamp
Introduction to using MediaWiki-Vagrant to manage a development environment for hacking on MediaWiki. We'll do a really quick high level look at what Vagrant is and how MediaWiki-Vagrant uses and extends it. Then we'll learn just enough Puppet to understand what "roles" are and how to use them to configure your MediaWiki-Vagrant instance. Participants will then get hands on by creating roles to install and configure extensions used on Commons that are not yet available in MediaWiki-Vagrant.

How to help pywikibot
Pywikibot is the most popular framework for running bots but how we can help improving pywikibot? There are several ways to help including solving and reporting bugs, wrangling bugs, bug triage and areas of developing including support of Wikibase and Wikidata, porting functionality from compat to core, and or network optimization (in order to reduce pressure on WMF servers)

Interested persons:
 * 1) Ladsgroup
 * 2) Maximilianklein
 * 3) Multichill I would like to see a session on the future of Pywikibot (like this) but I'm not sure if we have the right people at this hackathon. Maybe we should move that part to the Wikimania hackathon.
 * 4) Antoine "hashar" Musso would like to setup an integration test that runs pywikibot against MediaWiki core master and wmf branches.
 * 5) whym - interested in adding more tests for scripts I use.

Translate extension workshop
Nikerabbit is there to explain how the Translate extension works. Let's fix your most wanted (or hated) Translate bugs together or work on new features.

Possible bigger topics to work on, depending on the interest:
 * Repository management. Translatewiki.net is using a collection of shell scripts to manage all repositories where translations are exported to and imported from. Lack of better repository management is blocking further progress on areas like automation of imports and exports.
 * How will page translation work with Parsoid and VisualEditor.
 * Let's provide more useful statistics about translation activity in nicer format.
 * Translation memory improvements.

Translate extension provides an translation editor, support for many different types of content, translation memory, statistics ad lots more. It is also very old and big extension, while also adopting new technologies like composer and CSS grid based interface.

Working with Historical Monuments Data
In this workshop we will look into ways how to work with data concerning historical monuments in the context of Wikipedia/Wikidata. Aspects that could be covered are:


 * Transfer historical monuments data from lists on Wikipedia to Wikidata;
 * Import historical monuments data from third party data sets to Wikidata;
 * Generate monuments lists in Wikipedia based on data stored in Wikidata;
 * Find easy ways to edit monuments lists in Wikidata;
 * Use historical monuments data stored in Wikidata in a mobile web application (How does it work in practice? What are the requirements regarding the data in Wikidata?);
 * Document the workflow and estimate the resources (volunteers, competencies, etc.) needed to include historical maps from Switzerland into the Wikimaps project framework;
 * Use historical maps from Switzerland, prepared by tools provided by the Wikimaps project, in a mobile web application focusing on historical monuments.

There are thematic overlaps with the proposed activities regarding the Wikimaps project, historical maps of Zurich, and the integration of open government data in Wikidata (see above).

Complex questions are discussed in depth until reaching a decision.

Future of version control, bug reporting and other developer tools

 * See also Requests for comment/Phabricator/Plan.

It's been 2 years since we setup the current infrastructure around developer tools with Gerrit and Jenkins. Not everyone's happy and things break more often than we like. Additionally there's been rumblings for years about getting rid of Bugzilla. I think it's high time we have a discussion about what we envision our ideal development environment to be and figure out what it would take to get us there. Are there any tools (hint hint: Phabricator) that can help get us most of the way there?

OpenPGP/GnuPG key signing party
A OpenPGP/GnuPG key signing party to strengthen the Web of Trust. There is no central key registry for this key signing party. Instead it will simply be a paper slip exchange. Bring
 * paper slips with your key id, fingerprint, name & emails, and
 * something to identify yourself (usually a government-issued identification, such as a passport).

If you need to make paper slips, you can for example use generators, or print copies of the output of

Proposals that seem to need clarification. Feel free moving them in any of the categories above.

Local Wikipedia forks
"Semi-autonomous instances of localized Wikipedia". Expand on the work of SOS Children, the Rachel Project to create packaged snapshots of Wikipedia contents that can be deployed on local storage e.g. SD cards in a tablet computer, 3G WiFi router, etc. and on a Raspberry Pi, etc. Ideally there'll be bi-directional updates from the local instance to Wikipedia and from Wikipedia to the local instance - asynchronous synchronization. People using one of these snapshot instances would be able to create new content and revise existing contents. One of the main goals is to help extend the reach locality and relevance of Wikipedia for people throughout the world.

I've been doing some work in this area already and will bring hardware, etc. to demo and test our work.

There's lots of known-unknowns for this project. With your help I hope we'll be able to

Interested persons:
 * 1) Julian Harty
 * 2) Seb35 I’m thinking about an asynchronous MediaWiki with a git-like workflow; I was not aware of existing ideas like the pages linked here.
 * 3) (add yourself)

Possibly interested:
 * 1) Nemo Not interested if it's yet another offline Wikipedia work, but I'd be interested if this was focused on Kiwix/ZIM incremental updates + the ability to edit locally (and then submit changes).
 * 2) Waldir Only interested in the bi-directionality (i.e. "edit feature"). cf. Distributed Wikipedia.

Comments:
 * Except for the "edit feature", what you mean seems to exist already. At least two Kiwix developers will be there during the 3 days. 188.61.123.117 09:11, 7 February 2014 (UTC)

Extend VisualEditor
VisualEditor has been around for quite a while. As an extension developer, it's time to think about how you can integrate your extension. There are several topics that we'll need to talk about: We as a developer community need to explore the workings of the VE, this session is intended to be a starter.
 * How can my extension make use of / add to the VE?
 * Does my code survive the round trip?
 * How is my extension's code displayed in the VE?
 * How can I write dialogs that allow the user to easily edit my tags?
 * How can I add functionality to the VE in general?

The new face of MediaWiki.org
There's an initiative to rework MediaWiki.org. We should discuss the plans and outcomes in order to make MediaWiki.org a site that is easy to use and valuable to all of us, be it users, site maintainers, core and extension developers and any other interested parties. Let's go over the new design and make this a state-of-the-art site a so wide spread software like MediaWiki deserves!
