Create the repository on `front0`. Ex: sudo su - git cd repositories mkdir emacsconf-2024-private.git cd emacsconf-2024-private.git git init --bare 2. Edit `gitolite-admin/config/gitolite-conf`. Add lines for the group and the repo. Commit and push. Ex: @emacsconf-2024-org = bandali sachac ... repo emacsconf-2024-private RW+ = @admins @emacsconf-2024-org orga 3. Clone the private repository into the appropriate location. `git clone git@git.emacsconf.org:emacsconf-2024-private private` ## Create the public organizers’ notebook in the wiki Ex: 2024/organizers-notebook/index.org # Phases and lessons learned ## Draft CFP Create linked pages - [ ] year index - [ ] volunteer page - [ ] submit page ### How to mark pages as drafts Put inside double square brackets: `!template id=pagedraft` ### Previous years [2023](file:///home/sacha/proj/emacsconf/wiki/2023/cfp.md) ### Lessons learned - 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 ## 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: Hello, ....! 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! 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 - 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 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 - - - - - Update talks.md to refer to watch.md as well ## Process uploaded files Basic setup: 1. Set up the media server and symlinks: README.org (Media). 2. Set up the prerec processing areas on res: README.org (Processing prerecs). 3. Set up the caption processor on res: README.org (Captioning). Process: 1. Review uploaded files with 2. Open the JSON for the file you want to process and use . 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. or 3. ## Generate assets ### In-between pages - Make the $year/assets/in-between directory and copy the template.svg from the previous year. - ### Intros - In an empty VTT file, - Record the audio and get captions - Splice together into a file that will be processed with subed-record-compile-video. ## Prepare the infrastructure Checklist: - [ ] IRC - [ ] Manual announcements - [ ] Automated announcements - [ ] Web conference - [ ] Streaming assets - [ ] Overlays - [ ] Intros - [ ] OBS - [ ] VNC - [ ] Publishing to the wiki - [ ] Publishing to the media server - [ ] Etherpad - [ ] Mumble - [ ] Icecast ## Getting ready for captions Onboarding: - Add captioner to conf.org with the `:caption:` tag, under a Volunteers heading with the `volunteer` tag. Make sure the `EMAIL` property is set. - Add captioner to emacsconf-org mailing list. - Send backstage information . (Can be sent to all captioning volunteers with ) # General infrastructure ## Icecast Success: You can use [OBS+VNC to record](#obs-instructions), and the results can be viewed by mpv. - [X] Gen - [X] Dev Also, recordings are available in /data. New year: 1. Reprovision with ansible-playbook -i inventory.yml prod-playbook.yml --tags stream so that the year is updated in the configuration. 2. SSH to live0.emacsconf.org and run `/etc/init.d/emacsconf stop`. Confirm that icecast has stopped with `ps | grep emacsconf`; if not, kill the process. Start it again with `/etc/init.d/emacsconf start` 3. To test, you can use FFmpeg like this for the gen stream: ffmpeg -y -f lavfi -i testsrc=size=1280x720:rate=10 -i background-music.opus \ -c:v libvpx -b:v 500K -crf 25 -b:a 128k \ -content_type video/webm "icecast://emacsconf:$EMACSCONF_ICECAST_SOURCE_PASSWORD@live0.emacsconf.org:8001/gen.webm" For dev: 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:$EMACSCONF_ICECAST_SOURCE_PASSWORD@live0.emacsconf.org:8001/dev.webm" and then view it with mpv https://live0.emacsconf.org/gen.webm ## Watching pages Success: You can watch at . - [X] goes to the current year’s page. - [X] gen stream works in the browser - [X] dev stream works in the browser - [X] Schedule is correct New year: 1. ansible-playbook -i inventory.yml prod-playbook.yml –tags live 2. Republish with . 3. Update front:/var/www/live.emacsconf.org. Set up test streams (see ffmpeg instructions from [Icecast](#icecast)) and then: ## VNC We use VNC to connect to the X servers on res.emacsconf.org so that we can stream from it. Success: - [X] Confirm that you can connect to emacsconf-gen via VNC - [X] Confirm that you can connect to emacsconf-dev via VNC Setting up - #### Instructions NOTE: VNC+OBS doesn’t work well if you have a window manager that automatically resizes windows, like i3. Please configure your window manager so that the VNC window is not resized. 1. Install a VNC viewer on your system (ex: tigervnc-viewer). 2. Set up your local environment: - gen: `export TRACK=gen; export TRACK_PORT=5905; export SSH_PORT=46668` - dev: export TRACK=dev; export TRACK\_PORT=5906; export SSH\_PORT=46668 3. Copy the password: scp emacsconf-$TRACK@res.emacsconf.org:~/.vnc/passwd vnc-passwd-$TRACK -p $SSH\_PORT 4. Forward your local ports and connect via VNC viewer to the appropriate forwarded port from your laptop: ssh emacsconf-$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-$TRACK & If you get the following error: channel 2: open failed: connect failed: Connection refused CConn: End of stream CConn: The connection was dropped by the server before the session could be established. then the VNC server hasn’t started yet. You can start it with ssh emacsconf-$TRACK@res.emacsconf.org -p $SSH_PORT /home/emacsconf-$TRACK/bin/track-vnc and then connect with: xvncviewer 127.0.0.1:$TRACK_PORT -shared -geometry 1280x720 -passwd vnc-passwd-$TRACK & ## Streaming with OBS Success: Confirm that you can stream - [X] gen - [X] dev New year: reprovision with ansible-playbook -i inventory.yml prod-playbook.yml --tags obs so that the year is updated in the shell scripts. #### Instructions 1. [Connect to the VNC session for the track.](#vnc-instructions) 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: mpv https://live0.emacsconf.org/$TRACK.webm & ### Icecast Success: You can use [OBS+VNC to record](#obs-instructions), and the results can be viewed by mpv. - [ ] gen - [ ] dev New year: reprovision with ansible-playbook -i inventory.yml prod-playbook.yml --tags stream 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`. ## IRC web client Success: - [X] You can join from - [X] You can join from 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, ). 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 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 . The public media directory should have the files and the entry should be in the index. Switching it back to `TO_STREAM` and calling 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`. ## Automated IRC announcements Success: - [ ] When a talk starts playing, it is announced in the relevant channel ## Manual IRC announcements Success: - [X] You can /opall, /conftopic, and /broadcast ## Low-res stream ## Restream to YouTube ## Restream to Toobnix # Other process notes ## Adding another user to BBB ssh bbb.emacsverse.org docker exec -it greenlight-v2 bundle exec rake user:create["USERNAME","EMAIL","PASSWORD","user"] ## Ansible git clone git@git.emacsconf.org:pub/emacsconf-ansible
