*** Lessons learned
:PROPERTIES:
:CUSTOM_ID: draft-cfp-lessons-learned
:END:

- Maybe incentivize proper timezone specification by saying we can translate times to their local time?
- Make sure to include cfp.org as an attachment instead of inline
- bandali likes having the commitment to freedom section in the CFP as a form of activism.
- Ask for public e-mail or contact information, IRC handle in CFP.
- Nudge everyone towards 5/10 or 20 minutes, and consider < or > on a case-by-case basis.
  - In previous years, we offered 40 minutes as a
    regular choice, but that was difficult because
    we had to figure out how to squeeze lots of
    talks into the schedule and we didn't know
    what could be shortened. In 2022, we asked
    people to provide quick outlines for 10-, 20-,
    and 40-minute formats if they wanted a long
    talk slot, which was helpful in prioritizing.
    In 2023, we just suggested 5/10 and 20-minute
    slots knowing that there would probably be
    plenty of time for Q&A, with some longer talks
    approved on a case-by-case basis. Because
    talks are (ideally) prerecorded, 20 minutes
    seems to be a good length to get into
    something interesting while leaving time for
    Q&A so that people could dive deeper into
    particular things that interested them.
- Rolling acceptances were very nice. We gave
  people a week to respond, which felt a little
  quick sometimes, but gave people enough time to
  speak up to see if they had any red flags or
  suggestions.
- We didn't extend the CFP period in 2023, great!
- Two streams worked out well. Sunday morning had network congestion issues, so keep an eye out for those.
- It’s easier for us to extend beyond 5pm than to go before 9am
  (especially for Pacific time).  Extending beyond 5pm puts strain on
  European organizers and volunteers, though.
- Put the speaker introduction right after the talk description for easier web page copying.
** Announce

- Post CFP to emacsconf-discuss, reddit.com/r/emacs, and in Emacs News
- Submit to  https://foss.events/

** Process proposals

1. In the private repository, create a conf.org.
2. Set ~emacsconf-org-file~ to its location.
3. Create a heading for Submissions and set ~CUSTOM_ID~ to ~submissions~.
4. Prepare the ~prepare~ and ~submit~ pages on the wiki.

When proposals come in:

  1. Acknowledge with an e-mail along the lines of:

    #+begin_example
    Hello, ....!

    <feedback> We'll wait another week in case anyone else wants to
    chime in before I add it to the wiki and send further notes. :) Thanks for
    submitting this!
     #+end_example

  2. Use ~emacsconf-mail-add-submission~ if it works, or create the entry and paste it in.
     ~org-toggle-item~ can help convert Org-style headings into a nested list.
  3. Set the following fields (~my/org-set-property~
     can be helpful): EMERGENCY, Q_AND_A,
     AVAILABILITY, NAME, PRONOUNS, TIME,
     SLUG, EMAIL, NAME_SHORT, CUSTOM_ID,
     TRACK, TIMEZONE, CATEGORY, DATE_SUBMITTED,
     PUBLIC_EMAIL
** Accept proposals

Setup:

1. Create YYYY/talks.md.

For each talk:

1. Set up "Talk abstract" and "Talk details" sections in the conf.org talk subtree.
2. Change status to ~TO_CONFIRM~.
3. Create wiki page with ~emacsconf-publish-add-talk~.
4. Use ~emacsconf-publish-info-pages~ and ~emacsconf-publish-schedule~ as needed.
5. Send acceptance e-mail with ~emacsconf-mail-accept-talk~
** Draft schedule
:PROPERTIES:
:CUSTOM_ID: draft-schedule
:END:
- Create entries for opening and closing remarks
  - FIXED: t
  - SCHEDULED
  - TIME: 10
  - BUFFER: 0
  - CUSTOM_ID:
  - SLUG:
  - Q_AND_A: pad
- Create draft-schedule section in the public organizers notebook for the year
- Add missing items to plan
** Set up backstage and upload

See [[emacsconf-ansible:README.org]].

Lessons learned:

- Next year, let's get upload.emacsconf.org in place as the domain name so that people don't try to FTP files to it.

** Post the schedule

- [[elisp:(setq emacsconf-publishing-phase 'schedule)]]
- elisp:emacsconf-publish-info-pages
- elisp:emacsconf-publish-schedule-org-files
- elisp:emacsconf-ical-generate-all
- Update talks.md to refer to watch.md as well


** Process uploaded files

Basic setup:

1. Set up the media server and symlinks: [[emacsconf-ansible:README.org]] (Media).
2. Set up the prerec processing areas on res: [[emacsconf-ansible:README.org]] (Processing prerecs).
2. Set up the caption processor on res: [[emacsconf-ansible:README.org]] (Captioning).

Process:

1. Review uploaded files with elisp:emacsconf-upload-dired
2. Open the JSON for the file you want to process and use elisp:emacsconf-upload-copy-from-json .
   If more than one file uses the same extension, provide a suffix to disambiguate them.
3. On res:
   1. Create a directory ~/current/files/$slug.
   2. Copy the uploaded file from ~/cache as =$video_slug--original.$extension=, or use =rename-original.sh $slug $file=.
   3. Call =process-prerec.sh $file=.
4. When the screens are finished, do locally:
   1. update-cache on my computer.
   2. elisp:emacsconf-publish-cache-video-data or elisp:emacsconf-cache-all-video-data
   3. elisp:emacsconf-publish-backstage-index
** Generate assets
*** In-between pages
- Make the $year/assets/in-between directory and copy the template.svg from the previous year.
- elisp:emacsconf-stream-generate-in-between-pages
*** Intros
- In an empty VTT file, elisp:emacsconf-subed-intro-subtitles
- Record the audio and get captions
- Splice together into a file that will be processed with subed-record-compile-video.
** Prepare the infrastructure

- Send backstage information elisp:emacsconf-mail-backstage-info-to-volunteer . (Can be sent to all captioning volunteers with elisp:emacsconf-mail-backstage-info-to-captioning-volunteers)
* General infrastructure
** Icecast
:PROPERTIES:
:CUSTOM_ID: icecast
:END:

Success: You can use [[#obs-instructions][OBS+VNC to record]], and the results can be viewed by mpv.
- [X] Gen
- [X] Dev
Also, recordings are available in /data.

New year:

1. Reprovision with
   #+begin_src sh :eval no
   ansible-playbook -i inventory.yml prod-playbook.yml --tags stream
   #+end_src
   so that the year is updated in the configuration.
2. SSH to live0.emacsconf.org and run ~/etc/init.d/emacsconf stop~. Confirm that icecast has stopped with ~ps | grep emacsconf~; if not, kill the process.
   Start it again with ~/etc/init.d/emacsconf start~
3. To test, you can use FFmpeg like this for the gen stream:
   #+begin_src sh
   ffmpeg -y -f lavfi -i testsrc=size=1280x720:rate=10 -i background-music.opus \
                            -c:v libvpx -b:v 500K -crf 25  -b:a 128k \
                            -content_type video/webm "icecast://emacsconf:$EMACSCONF_ICECAST_SOURCE_PASSWORD@live0.emacsconf.org:8001/gen.webm"
   #+end_src
   For dev:
   #+begin_src sh
   ffmpeg -y -f lavfi -i testsrc=size=1280x720:rate=10 -i background-music.opus \
                            -c:v libvpx -b:v 500K -crf 25  -b:a 128k \
                            -content_type video/webm "icecast://emacsconf:$EMACSCONF_ICECAST_SOURCE_PASSWORD@live0.emacsconf.org:8001/dev.webm"
   #+end_src
   and then view it with
   #+begin_src sh
   mpv https://live0.emacsconf.org/gen.webm
   #+end_src
** Watching pages
:PROPERTIES:
:CUSTOM_ID: watch
:END:

Success: You can watch at https://live.emacsconf.org.
- [X] https://live.emacsconf.org goes to the current year's page.
- [X] gen stream works in the browser
- [X] dev stream works in the browser
- [X] Schedule is correct

New year:
1. ansible-playbook -i inventory.yml prod-playbook.yml --tags live
2. Republish with elisp:emacsconf-publish-watch-pages.
3. Update front:/var/www/live.emacsconf.org.

Set up test streams (see ffmpeg instructions from [[#icecast][Icecast]]) and then:

** VNC
:PROPERTIES:
:CUSTOM_ID: vnc
:END:

We use VNC to connect to the X servers on res.emacsconf.org so that we can stream from it.

Success:
- [X] Confirm that you can connect to emacsconf-gen via VNC
- [X] Confirm that you can connect to emacsconf-dev via VNC

Setting up
- elisp:emacsconf-publish-res-index

*** Instructions
:PROPERTIES:
:CUSTOM_ID: vnc-instructions
:END:

NOTE: VNC+OBS doesn't work well if you have a window manager that
automatically resizes windows, like i3. Please configure your window
manager so that the VNC window is not resized.

  1. Install a VNC viewer on your system (ex: tigervnc-viewer).

  2. Set up your local environment:

     - gen: ~export TRACK=gen; export TRACK_PORT=5905; export SSH_PORT=46668~
     - dev: ~export TRACK=dev; export TRACK_PORT=5906; export SSH_PORT=46668~

  3. Copy the password:

     scp emacsconf-$TRACK@res.emacsconf.org:~/.vnc/passwd vnc-passwd-$TRACK -p $SSH_PORT

  4. Forward your local ports and connect via VNC viewer to the
     appropriate forwarded port from your laptop:

     #+begin_example
     ssh emacsconf-$TRACK@res.emacsconf.org -N -L $TRACK_PORT:127.0.0.1:$TRACK_PORT -p $SSH_PORT &
     sleep 5   # Give it time to establish the tunnels
     xvncviewer 127.0.0.1:$TRACK_PORT -shared -geometry 1280x720 -passwd vnc-passwd-$TRACK &
     #+end_example

If you get the following error:

#+begin_example
channel 2: open failed: connect failed: Connection refused
CConn:       End of stream
CConn:       The connection was dropped by the server before the session could
             be established.
#+end_example

then the VNC server hasn't started yet. You can start it with

#+begin_src sh :eval no
ssh emacsconf-$TRACK@res.emacsconf.org -p $SSH_PORT /home/emacsconf-$TRACK/bin/track-vnc
#+end_src

and then connect with:

#+begin_src sh :eval no
xvncviewer 127.0.0.1:$TRACK_PORT -shared -geometry 1280x720 -passwd vnc-passwd-$TRACK &
#+end_src

** Streaming with OBS
:PROPERTIES:
:CUSTOM_ID: obs
:END:

Success: Confirm that you can stream
- [X] gen
- [X] dev

New year: reprovision with

#+begin_src sh :eval no
ansible-playbook -i inventory.yml prod-playbook.yml --tags obs
#+end_src

so that the year is updated in the shell scripts.

*** Instructions
:PROPERTIES:
:CUSTOM_ID: obs-instructions
:END:

1. [[#vnc-instructions][Connect to the VNC session for the track.]]

2. Start *recording* (not streaming). If you don't see OBS when you connect, it's probably on workspace 2, so you can switch with Alt-2. If you still don't see it there, you can open a terminal with Alt-Enter and then run ~track-obs~. After you start recording, confirm that it is now broadcasting to the stream.

3. Verify with MPV on your local system:

   #+begin_example
   mpv https://live0.emacsconf.org/$TRACK.webm &
   #+end_example

*** Icecast
:PROPERTIES:
:CUSTOM_ID: icecast
:END:

Success: You can use [[#obs-instructions][OBS+VNC to record]], and the results can be viewed by mpv.
- [ ] gen
- [ ] dev

New year: reprovision with

#+begin_src sh :eval no
ansible-playbook -i inventory.yml prod-playbook.yml --tags stream
#+end_src

so that the year is updated in the configuration.

This is on live.emacsconf.org and can be restarted with =/etc/init.d/emacsconf restart=.
** Shell scripts

Success: From the commandline, hosts can:
- [X] play just the intro: intro $SLUG
- [X] play a file without an intro: play $SLUG
- [X] play a file with an intro: play-with-intro $SLUG (hmm, this didn't show the subtitles)
  ah, it's because the intros need to be in the cache dir?
- [X] open the Q&A for a talk: handle-qa $SLUG
  - [X] open the pad: pad $SLUG
  - [X] open BBB: bbb $SLUG
- [ ] do the whole thing: handle-session $SLUG
- [ ] rebroadcast the other stream:
  - rebroadcast gen
  - rebroadcast dev
- [ ] control background music: music, stop-music

Setup:
- OBS must be streaming from the stream you're testing. [[#obs][Streaming with OBS]]
- You may want to generate test assets and copy them over to the assets/stream directory.
- Generate all the overlays and copy them to assets/overlays
- Set up the assets/music directory
** Backstage

** IRC web client

Success:
- [X] You can join from https://chat.emacsconf.org
- [X] You can join from https://live.emacsconf.org and the channels end up as the latest ones

Remember to schedule a task to ask libera.chat to increase the number of users it will accept from chat.emacsconf.org to avoid connection exhaustion errors.

Message I've posted to support@libera.chat:

Thank you for running libera.chat. We're looking forward to using IRC
(#emacsconf-gen, #emacsconf-dev) for the discussions for the upcoming
EmacsConf (Dec 7-8, https://emacsconf.org). In the past, we've needed to
coordinate with Libera staff to increase the number of connections
allowed from chat.emacsconf.org during conference days in order to avoid
connection exhaustion errors. Is that something we can plan now or would
you like me to bring it up a few days before the conference?
** Etherpad

Success:

- [X] pad.emacsconf.org redirects to this year's entry
- [X] Each talk has its own Etherpad
** Publishing media to the server and to the wiki
:PROPERTIES:
:CUSTOM_ID: media
:END:

Start of year:

1. Set =media_protect_root= to true in Ansible =group_vars/all.yml=.
2. =ansible-playbook -i inventory.yml prod-playbook.yml --tags media=
3. Generate the index with =emacsconf-publish-update-media=

Confirm by setting a submitted talk to =PLAYING= and testing with
elisp:emacsconf-publish-media-files-on-change . The public media
directory should have the files and the entry should be in the index.
Switching it back to =TO_STREAM= and calling
elisp:emacsconf-publish-media-files-on-change should remove it.

*** TODO Switch public media to unprotected root before the conference

1. Clear public media directory.
2. Set =media_protect_root= to false in Ansible =group_vars/all.yml=.
3. =ansible-playbook -i inventory.yml prod-playbook.yml --tags media=

You can generate the index with =emacsconf-publish-update-media=.
