Web Engines Hackfest 2025

From Monday, June 2nd to Wednesday, June 4th, 2025, the Web Engines Hackfest 2025 will be held in Coruña.

If you need tutoring for this week, send me an email and we’ll try to accommodate a slot on Friday.

If you’d like to watch or participate in any of the Web Engines Hackfest sessions, these are the links.

• Monday 2nd: Talks live stream at https://www.youtube.com/live/De4n7vjEO1o
• Tuesday 3rd & Wednesday 4th: Links to conference calls in each breakout session issue. In each session, you’ll find a link to a meeting using jitsi (an open-source, secure, and privacy-focused platform for video conferencing) and a link to the notes using hackmd (a collaborative, real-time Markdown-based note-taking platform). I think anyone can join even if they haven’t registered, but I’m not sure.

In particular, we will participate in the session Involving students and researchers in web engine implementation #47 organized by Barash:

• Date & Time: Wednesday 4th June at 12:00 CEST (local time)
• URL: https://meet.jit.si/WEH2025-Students
• Notes: https://hackmd.io/@rego/WEH2025-Students/edit
