  3. Face search: upload or paste a face image, and the tool will try to identify and locate that person across images and videos, including timestamps where they appear
  4. Audio search: search within audio files to find relevant segments — e.g.: sound of a bullet

Phabricator task: https://phabricator.wikimedia.org/T424464
Brief description: I have developed a communication tool to allow GLAM professionals to report bugs and make feature requests without needing a phabricator account or needing to actually use phabricator - this was inspired by lived experience noticing that the complaints from end-users in this community rarely made their way to tech contributors who could implement a fix! This tool contains both a submission form that has project tags mapped to PHIDs for phabricator boards, along with a guided step format form that assists with a better ticket generation and mapped priority values; additionally it contains a live tracker of tasks submit via this tool so users can track resolution of the tasks. This is an early prototype and needs some user testing and feedback!

59. Add OpenHistoricalMap support to Wikipedia articles with interactive map features
Phabricator task: https://phabricator.wikimedia.org/T420120
Brief description: GlobStory is an experimental Wikipedia userscript that adds spatial and temporal context to Wikipedia articles. The script detects place names and historical years mentioned in article text and connects them to an interactive map powered by OpenStreetMap and OpenHistoricalMap. This allows readers to explore the geographic and historical context of events while reading.

61. VisualEditor automatic edit summary generation
Phabricator task: https://phabricator.wikimedia.org/T425276
Brief description: It would be helpful to offer users a suggested summary of their edit. They may want to alter it, but we can start them off with something potentially helpful -- "added references to Controversies section", etc. Compared to WikiEditor, VisualEditor already generates visual diffs of your changes, which means that most of the data we'd need for this is being generated and is available in a conveniently semantically-marked-up format.

63. Running parser tests in PHPUnit without dynamic test generation
Phabricator task: T422866
Brief description: parser tests uses a custom DSL to compactly specify content transformation tests (wikitext -> html, html -> wikitext, and a number of other modes) with a variety of wiki-configuration and test-configuration options. So far, even the PHP Unit test runner has relied on existing dynamic test generation code. But, this blocks upgrading to PHPUnit 10 and to run tests in parallel.
Relevant links:
Contact(s): Subbu, Emanuele / Daimona
Status: very early prototype. We now generate a number of PHPUnit test files from the parser test txt files which can then be run via composer phpunit. Of all the transform modes in these files (wt2html, html2wt, wt2wt, selser, etc.), about 50% of wt2htmll wt2wt, html2wt, html2html tests now pass in Parsoid's standalone mode. There is still a lot more work to do to ensure all existing parser-test pass in all content transform modes in both Parsoid-standalone, Parsoid-integrated, and legacy modes, but we are now significantly unblocked and now it is a matter of working through failures and functionality gaps.

@BPiovesan-WMF I received this feedback/suggestions from @simon04 by email:

📋 Hackathon Showcase Efficiency: Structured Feedback

  1. Hardware & Infrastructure

These points focus on providing a standardized environment to eliminate "it works on my machine" syndrome.

  • Standardized Hardware: Provide a dedicated MacBook for presentations starting on Day 3.
  • Peripherals: Ensure a physical mouse is available for easier navigation during high-pressure demos.
  • Remote Assistance: Install and enable remote control software to allow the tech team to assist with troubleshooting or browser cleanup during transitions.
  1. Browser & Software Configuration

To ensure a professional and clutter-free visual experience, the following setup is recommended:

  • Clean Session: Use a separate private window in Chrome exclusively for the showcase.
  • Tab Management: Keep the Etherpad pinned as the first tab; ensure no extraneous tabs are open to reduce confusion.
  1. Presenter Guidelines (The "Demo Day" Protocol)

Clear instructions to help participants prepare for the technical realities of a public presentation.

  • Video Pre-production:
    • Record demos using [Tool X/Y/Z].
    • Upload recordings to [Platform X/Y/Z] as a fallback.
  • Resource Linking: Skip verbal explanations of code locations; instead, place all links in the Etherpad.
  • Zero-State Assumption: Presenters must assume the demo machine is not their own and that they are not logged in to any personal accounts or platforms.
  • Contingency Planning: Advise all teams that live demos are high-risk and likely to fail; encourage pre-recorded backups. ---

I don't think all suggestions are easily implemented, but IMO the suggestions are mostly achievable and some quick wins would make the showcase run more smoothly. Stretch goals would include having two computers so one presenter would be showcasing on one side of the stage, and another would be setting up their presentation on the other side of the stage.
