Quick tutorial made by the organizers (watch in full screen):

Firefox was used for this tutorial. In Chrome, permission to access camera and microphone feed can be given on the right of the address bar.

Technical information:

• Gather is supported on any desktop or laptop (no tablets and phones), and any OS (Windows, Mac OS, Linux). Camera and microphone are required.
• Only supported in Chrome and Firefox.
• Make sure your browser is up to date.*
• Using a VPN is not recommended (which also applies to Zoom).*
• Make sure "x" is not a shortcut key of a browser plug-in (disable those if needed).

*Based on experiences of the organizers.

On Tuesday, 17:45 CEST, we will host a quiz on Zoom in order to give you a break from the ADFOCS topics.

How to participate:

• Join on Zoom with the provided link. We break you up into teams (using break-out rooms in Zoom).
• Quiz has five rounds with different themes, and works as follows.
• Quiz master releases Google Form with questions, and you and your team members try to solve these (in the break-out room).
• Team captain fills in the form and submits it at the end of the round. No late hand-ins.
• Answers will be given in between rounds.

Web searches are not allowed! We're testing your knowledge, not your Googling skills...

Winners will be announced at the end of the MPI-session on Thursday (17:45-18:30 CEST).
Honorable mention for most original team name!

Below the five question forms of the quiz (choose any team name+captain to move on to the questions). And click here for a PDF with the answers.

• Round 1: Know your community.
• Round 2: Test your algorithmic skills.
• Round 3: TCS/Math musical parody trivia.
• Round 4: Visualization.
• Round 5: Get to know MPII!

This year's ADFOCS features three lecturers. Our invited speakers give five lectures with subsequent exercise and discussion sessions. These sessions will take place daily from 14:30 to 18:30 UTC+2 (CEST). There is also a (pub)quiz planned.

On Tuesday the Fair Division lecture starts at 15:50 CEST (followed by a short break and exercise session).
