Wikimedia CH/Tech boost

Wikimedia CH sometime organizes a Tech Boost during which a project will be boosted with development support.


During a Tech Boost, at least one IT staff member will be available in this channel:


During these meetings you can meet one of these developers and system administrators, have a Jitsi Meeting conference with them, discover what they do, what are the current issues, share your ideas about a development, report bugs, leave feedback etc.


Here a showcase of some projects often involved in Wikimedia CH Tech boosts:

Description and challenges


core innovation principle: Factory is an independent community project powered by the MediaWiki software. Since 2022, it's hosted in the Wikimedia CH's infrastructure.

Boosting this entry, the technical quality of the project will be advanced.

WMCH Contributors annual report


core innovation principle: Incubator

The WMCH contributors annual report is a tool born in 2020 to generate community reports, useful to give prizes to the community.

This project can be boosted to improve criteria, data collection methods, performances, maintainability, documentation, user interface, etc.


Activities that can be boosted:

  • phabricator:T277279 - allow to display data directly online (sort by whatever column, search for an user, download, etc.) (expected max 1 working day)
Community technical support


core innovation principle: Pit-stop

During this boost we will invest some development for community templates and Scribunto Lua modules (introducing new functionalities, fixing bugs, improving documentation - whatever you think should be prioritized).

WMCH Matomo


core innovation principle: Safe space

During this boost Wikimedia CH can contribute in making reports with their dedicated Matomo instance. We can analyze web traffic on some websites and some interesting projects adopting very strange criteria, create new variables, check global performances, monitor internal goals, etc.

WMCH Cronos


core innovation principle: Incubator

During this boost Wikimedia CH will contribute in developing our "definitive wiki-calendar", a wiki-friendly calendar.

WMCH Grant


core innovation principle: Pit-stop

During 2020, Wikimedia CH implemented an automatic notification system in its Grant apply page. This activity is considered stable but can be boosted to introduce new features.

WMCH Tech Infrastructure


core innovation principle: Safe space

During this boost we will invest on new powerful tools for Wikimedia CH members or the Wikimedia community or we will just maintain Wikimedia CH components up 'n' running with latest security patches.

This takes in consideration documentation, release of our configurations to the community, installation of new features, hardening, etc.

Tech Documentation (at the moment accessible only to WMCH members)
MediaWiki goodies


core innovation principle: Pit-stop

Development activities related to MediaWiki integrations and extensions can be boosted.

Core Activities concluded:

Zabbix monitoring


core innovation principle: Safe space

The Zabbix monitoring is a Wikimedia CH activity that can be bosteed to be even more proactive in identifying an infrastructure problem in Wikimedia CH's servers hosting community projects.

Activities that can be boosted:

  • put the administration panel online (now very confidential)
  • more proactive monitoring


core innovation principle: Safe space

The WMCH LimeSurvey platform is available to WMCH staff members to conduct multi-language surveys, in a GDPR-friendly way and 100% data ownership.

Argo Wikimetrics


core innovation principle: Pit-stop

The Argo Wikimetrics was a project started in 2017 to collect metrics from wiki. Project information:

Wikimedia CH/Project/Argo Wikimetrics

Activities that can be boosted:

Bug fixes, addition of more languages, etc.

Fixed technical debt in Argo MetricsEdit

Tracked in Phabricator:
task T313737

Technical debt is when our airplane hasn't belts. That's not a problem for a prototype, but you know that will be to do. Today we fixed some small technical debt in the Argo Metrics platform.

The platform deals with querying databases of some wikis, and then do stats. The problem: some time ago, many databases were on the same Wikimedia server and you could make certain undocumented speculations. The instrument stopped working because all connections were being made to a server that did not have requested databases, but some others. In fact, you should, for each language, query the related hostname, pointing to the right server. So you cannot just query one hostname, but you should this operation dynamically, basing on what language you need.

But in addition, these servers are not public. So to query them, it is necessary to do some hacky things.

Today we have both corrected this tool and proposed a potential simplification for the whole community. Please see both tickets for info. --Valerio Bozzolan (talk) 21:56, 22 September 2022 (UTC)

Migrating from Gerrit to GitlabEdit

Since we are creating some new Wikimedia CH -related git repositories, it seems like a good thing to migrate our old repositories from Gerrit, which has a pretty complicated user interface, even just to find your repository by name, browse its README and see last commits and who can commit. So we started migrating everything to Wikimedia GitLab, which on the other hand is very cute and it has tons of stuff within a single click away. In addition, people are much more familiar with the concept of pull requests, so we expect more contributions (note: we will consider 1 contribution more than 0 contributions). --Valerio Bozzolan (talk) 21:35, 22 September 2022 (UTC)
