EmacsConf - Infrastructure and processes

Sacha Chua's EmacsConf presentation on EmacsConf

Q: What did you use to make this?
- All free/libre/open source tools:
  - One private Org file with speaker/volunteer/talk info
    - The talks were generally run using run-at-time, org-after-todo-state-change-hook, and some TRAMP (by the way, TRAMP does not like being run from timers at the same time, so we shifted some talks =) )
  - A public Org file for processes:
    - https://emacsconf.org/2022/organizers-notebook
    - https://emacsconf.org/2023/organizers-notebook
  - An ansible repo for configuration management: https://git.emacsconf.org/emacsconf-ansible/
  - Lots of Emacs Lisp: https://git.emacsconf.org/emacsconf-el/
  - TRAMP for writing files and running commands on remote computers
  - OBS for streaming, Icecast for sharing the stream with viewers
  - VNC for letting hosts and streamers connect to the same display for OBS streaming
  - screen for naming shell commands and making them easier to resume and kill
  - BigBlueButton for video Q&A
  - Mumble for speaking on the stream as well as for backstage communications
  - ERC for Internet Relay Chat within Emacs, The Lounge for web-based IRC
  - Ikiwiki for the wiki (editing through git commits)
  - Etherpad for collaborative note-taking
  - ffmpeg for reencoding videos to free (patent-unencumbered) formats and compressing them
  - Captioning (https://emacsconf.org/captioning):
    - OpenAI Whisper for computer-generated transcripts to be reflowed and edited by captioning volunteers
    - Some Emacs Lisp code to help with reflowing (emacsconf-reflow, in https://git.emacsconf.org/emacsconf-el/)
    - Aeneas (https://www.readbeyond.it/aeneas/) for synchronizing reflowed text with the audio files
    - subed.el (https://github.com/sachac/subed) for editing captions within Emacs (synchronizes with MPV)
  - MPV for playing videos (config tips: https://emacsconf.org/mpv/ https://git.emacsconf.org/emacsconf-ansible/tree/roles/obs/templates/mpv.conf)
Q: How do you have multiple font sizes, countdowns and clocks in

fundamental mode?

- A:

https://git.emacsconf.org/emacsconf-el/tree/emacsconf-stream.el

see emacsconf-stream-display-clock-and-countdown. You can propertize a string with face attributes and then insert it.
