Communications plan
Objectives:
- keep everyone in the loop without them feeling like they’re overloaded
Everyone:
- ☐ Call for participation (speakers and volunteers)
- ☐ Reminder about CFP
- ☐ Last call
Speakers:
- ☐ Send all speakers backstage access and upload instructions
- ☐ Send all speakers check-in instructions
Volunteers:
- ☐ Send captioning volunteers the backstage info
- ☐ Send past captioning volunteers an invitation to participate - ask when there’s a lot of load
- ☐ Ask for help with audio processing
Good/better/best
This table makes it easier to move the slider depending on who wants to volunteer and how much we can get done. At some point, we’ll figure out how to track our current status so we know what we need to scramble to do in order to get the conference off the ground. bold is our current goal. Feel free to volunteer for anything that interests you!
| Good | Better | Best | |
| Streaming | Regular stream | + alternate streams on PeerTube | + alternate streams on YouTube |
| 480p | Same on live | Separate node | Ansible setup |
| Audio normalization | Core org handling it | Other volunteer | Multiple volunteers |
| Video resolution | Usual reminders | Extra reminders | Everyone remembering to use a large font size |
| Intros | Standard, recorded | Reviewed by speakers | More details/context |

Legend:
- light blue: constraint is <= a time
- peach: constraint is >= a time
- solid line: Q&A will be through BigBlueButton web conference
- dashed line: Q&A will be IRC/Etherpad during the event or e-mail after the event
Notes:
- Updates:
- Removed graph, moved p-search earlier; also learning needs to be in the morning, so I moved pgmacs and org-teach around.
- Swapped org-teach and blee
- Extended blee
- Added org-update to Saturday morning, moving org-teach to Sunday afternoon
- Swapped students and literate for availability reasons
- Moved hyperdrive to the afternoon (swapping with flp) because of changed availability
- I fixed the time constraint for students (needs to be in the afternoon), so I moved hyperbole to the morning.
- General approach:
- I’ve mostly tried to alternate IRC/pad Q&A with live Q&A.
- 1.5 tracks keeps things faster-paced than the 2-track option.
- Sat:
- Gen track:
- papers, project, org-teach, flp, color should be pretty general
- color and theme are both theme-related. color needs to be in the morning and theme needs to be in the afternoon, so I put them on either side of the lunch break.
- Other afternoon talks: water and shell are by the same speaker. casual, hyperdrive, and writing will probably be good for a general audience. These speakers are only available in the afternoon, so this part of the schedule is a bit tight.
- I put emacs30 at the end of Saturday to act sort of as a keynote. Closing remarks on Saturday are usually very light, so we could skip them.
- Dev track:
- Gen track:
- Sun:
- Sunday morning last year had some packet loss issues at around 9:30, so we’ll start with some talks that don’t have BBB Q&A: students, links, regex
- blee and language are probably general-audience
- pgmacs, regex, and transducers are all development-oriented, but are on the general track for scheduling purposes. transducers can only be on Sunday afternoon at 4pm because of availability.
- I’ve separated hyperbole and hywiki by lunch so that people who are interested in that can attend the live Q&A for both without worrying about missing things.
- learning, sharing, literate will probably be good for a general audience

TODO BigBlueButton
- Plan: spin up Linode temporarily: BigBlueButton replacement
Notes
install, sizes
Prerequisites:
- BBB requires 4 CPU cores before it will install. bbb-conf.sh is fairly straightforward, so I guess we could spin down and then spin up again.
Steps:
- Run the BBB installer: ~./bbb-install.sh -v jammy-300 -s bbb.emacsverse.org -e emacsconf@sachachua.com -g ~
sudo apt install bbb-playback-videoand then follow the instructions at Server Customization | BigBlueButton .- https://docs.bigbluebutton.org/3.0/administration/customize/#mute-all-users-on-startup
I think it needs 4 CPU cores for regular running, too.
Sizing to shared 8GB 4 core for testing
linode-cli linodes resize 67329098 --type g6-standard-4 --allow_auto_disk_resize false
takes about 2 minutes
Sizing to shared nanode, dormant
linode-cli linodes resize 67329098 --type g6-nanode-1 --allow_auto_disk_resize true

CANCELLED Customize BBB to process at night
https://docs.bigbluebutton.org/3.0/administration/customize/ Change processing time
On a 2.2.x BigBlueButton server, the server will process recordings as meetings finish. You can restrict the recording processing interval to specific hours by creating the file /etc/systemd/system/bbb-record-core.timer.d/override.conf with the contents
[Timer] OnActiveSec= OnUnitInactiveSec= OnCalendar=21,22,23,00,01,02,03:*:00 Persistent=false
and do systemctl daemon-reload. This file overrides the timing of when systemd runs bbb-record-core.target. In the above example, recordings will start processing between 21:00 and 03:59.

Decisions
BigBlueButton replacement (BBB)
The server running bbb.emacsverse.org has been decommissioned, since the nonprofit that shared it with us is defunct.
- We’d like to figure out what our live Q&A setup is going to be for EmacsConf 2024 (Dec 7-8).
- Nice to have: Hosting for other Emacs meetups like Emacs APAC and OrgMeetup
- Stats from last year: 31 meetings, 84 unique users, 62 max simultaneous users, 6 max simultaneous meetings, 27 max users in one meeting, 36 unique talking
- also includes some notes on hosting
- Nice thing about running our own server: we can make one room per speaker, pre-assign their URLs, and let people stay as long as they want in recorded Q&A sessions
Recommendation:
We spin up a shared CPU 4GB under bandali’s Linode account (for bandwidth pooling and easier reimbursement), do the setup/testing, scale down as small as possible over the next few weeks, scale up to dedicated CPU 16GB a day or two before the conference, and keep it at that level until the recordings are all done. I have access to that Linode account, so I can set it up. If bandali can configure emacsverse.org to be handled by Linode, I can manage the DNS changes, or he can change bbb.emacsverse.org to the IP address of the new node.
Some options:
Linode with 16GB RAM and 8 cores
- Advantages: can experiment with both Galene and BBB, manage things ourselves, have filesystem access
- Disadvantages: needs someone to do it
- Base pricing
- Shared CPU 4GB 80GB storage: hourly USD 0.04, monthly USD 24
- Dedicated CPU 16GB: hourly USD 0.22, daily 5.28, weekly 36.96, monthly USD 144 - meets minimum requirements and can probably support 200 simultaneous (FAQ)
- Shared CPU 8GB 160GB storage: hourly USD 0.07
- Shared CPU 16GB 320GB storage: hourly USD 0.14
- Last year
- Block storage: $1/10GB/month
- 125M/hour - FAQ
- In 2023, we had 31 hours of trimmed recordings (main + answers),
- (* 31 0.125) 3.875, oh, maybe we can get away with 10GB storage and add another chunk of 10GB midway if we need it, or extend the dedicated
- Actually, block storage probably not needed if we’re going to keep the big instance up until the recordings are done
- Ideas
- We’re here – Option B: Run a slightly larger shared CPU instance from now until shortly before the conference, then scale up in case BBB does not work for installation/testing with less memory; block storage probably not needed
- (* 0.07 24 7 3) USD 35.28 for 8GB, total (+ 35.28 36.96) USD 72.24
- (* 0.14 24 7 3) USD 70.56 for 16GB, total (+ 70.56 36.96) USD 107.52
- Option A: Run a small instance continuously, scale up for the conference, pull the recordings off, spin the instance down - est total USD 60+tax
- There are three weeks between now and the conference (* 0.04 24 7 3) USD 20
- Last year, recordings were available within three days after the conference
- Let’s plan for a week at high capacity. (* 0.22 24 7) USD 36.96
- and a month of 10GB, possibly up to 30GB. USD 3
- That’s probably small enough that it doesn’t make as much sense to try to fully spin down for a week in between now and the conference (* 0.04 24 7) - which would save USD 6.72 but require figuring out backing up, etc.
- We’re here – Option B: Run a slightly larger shared CPU instance from now until shortly before the conference, then scale up in case BBB does not work for installation/testing with less memory; block storage probably not needed
Ask FSF if we can borrow their BBB or Galene, maybe limit it to cycling among 6 or 7 rooms
- Waiting for feedback; Corwin has asked them
- Pay for BigBlueButton hosting; can we find one that’s compatible with our commitment to freedom?

- custom domain, 600 concurrent users, USD 149/month
- Compare with Linode pricing
- Try to squeeze it onto res.emacsconf.org
- Tricky to run on a shared server; it likes to use a lot of ports and strongly recommends running it on its own server
- Go back to using meet.jit.si?
- Free:
- Need to check speed, reliability
- Can send RTMP from the meeting itself
- I attended Ihor’s OrgMeetup, which he hosted on meet.jit.si. I think he had bandwidth issues at some point and we lost his audio. I remember we ran into that problem before, too, when we used Jitsi for one of the Emacsconfs. Free Jitsi hosting might not be the right fit for us.
- Paid: USD 99/month + $0.01/min for recordings + $0.01 min (optional) for RTMP streaming
- Free:
- Galene?
- I checked out Galene in the last Emacs Berlin meeting. It’s promising, but I think the user interface might still need a bit of work. Simple deployment (run one Go binary, I think), but muting/unmuting doesn’t trigger enabling the microphone, and the chat was buggy to get to on my mobile device. Supposed to have support for raising hands.
