Speaker instructions

  • Please use your favourite IRC client to join #emacsconf-org on on the day of the conference. It should be a low-traffic channel for coordinating with speakers. Check in with sachac and bandali by saying hi, mentioning your name/talk if it's not obvious from your nick. Sacha (or the backup organizer) will coordinate with you for a tech check before you speak, and will give you the go-ahead to join a Jitsi session for the main presentation.
  • You can also join #emacsconf if you'd like to keep an eye on the conversations, or #emacsconf-questions for a more moderated view.
  • Please wear earphones or headphones in order to minimize microphone feedback.
  • Some of our attendees are blind, so please try to verbally describe what you're showing on the screen. We will also ask volunteers to describe what's going on in the #emacsconf channel (or maybe

  • Both organizers start recording again
  • Main organizer updates wiki with watching instructions
  • Backup organizer confirms watching instructions
  • Main organizer switches to agenda/opening image and does opening remarks
  • Backup organizer streams on phone so that she can monitor it while doing tech checks

Throughout the day

  • Backup checks #emacsconf-org channel and coordinates with speakers.
    • Planned talks: check if the speaker is available and can do a quick tech check
    • Lightning talks: Check who's ready to do their talk live with a quick tech check beforehand
      • All right, who wants to do the next lightning talk?
      • Please go to for a quick tech check.
      • When you're ready, close the tech check tab and go to ___.
  • Backup does tech check with speaker in a separate jitsi room and coordinates via IRC.
  • When ready, speaker joins main conference room and presents OR main organizer changes to a different room.
  • Backup organizer updates organizer's notebook with talk status
  • Backup organizer tweets talk info

Playing prerecorded videos

  • Main organizer introduces talk
  • Main organizer switches to OBS video player scene and plays video with video player
  • Main organizer posts "PLAYED: " in #emacsconf-org (so that it's easy to check which ones have been played already - maybe we should have a wiki page?)

In case of...

Technical issues / speakers not present

  • Main organizer makes brief announcement, then play prerecorded videos
  • If there are no more prerecorded videos, possibly open the floor to participants and treat it as a hangout

Speaker talking too long

  • If the next live presenter is lined up, main organizer gently nudges speaker to wrap up in five minutes
  • If no live presenter is lined up, backup organizer keeps checking the #emacsconf-org channel to see who will speak next, doing tech-check before giving the main organizer the go-ahead to nudge the speaker.

We don't have to bump live presenters for a prerecorded presentation, because we can play all the prerecorded presentations at the end.

Disruptive people joining Jitsi room

  • Main organizer switches to technical difficulties message or different Jitsi room
  • Backup coordinates with speaker to join a different room

Jitsi down

  • Main organizer describes technical difficulties and updates status page
  • Main organizer plays prerecorded videos while backup organizer retries Jitsi with help from volunteers, coordinating via IRC
  • TODO Back up plan in case Jitsi doesn't work? Say sorry and try again a different day?

After live presentations end

  • Main organizer makes closing remarks
  • Main organizer plays remaining prerecorded videos
  • After all prerecorded videos, main organizer says thank you, ends the stream, and ends the recording.

Lessons learned for next time

  • Indicate conference times and timezone in call for proposals.
  • Consider anonymized conference submissions to reduce bias. Encourage people to do personal outreach if there are people they would like to invite to speak.
