[Sacha Chua's EmacsConf presentation on EmacsConf](https://emacsconf.org/2023/talks/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.
