We like to have at least a month to work on audio
normalization and transcription, and we want
speakers to have at least a month to work on their
videos (considering early submissions will already
have gotten started on processing).

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

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!

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:
  - [2024-10-27 Sun] Removed emacsconf:graph, moved emacsconf:p-search earlier; also emacsconf:learning needs to be in the morning, so I moved emacsconf:pgmacs and emacsconf:org-teach around.
  - [2024-10-22 Tue] Swapped emacsconf:org-teach and emacsconf:blee
  - [2024-10-21 Mon] Extended emacsconf:blee
  - [2024-10-17 Thu] Added emacsconf:org-update to Saturday morning, moving emacsconf:org-teach to Sunday afternoon
  - [2024-10-15 Tue] Swapped emacsconf:students and emacsconf:literate for availability reasons
  - [2024-10-13 Sun] Moved emacsconf:hyperdrive to the afternoon (swapping with emacsconf:flp) because of changed availability
  - [2024-10-12 Sat] I fixed the time constraint for emacsconf:students (needs to be in the afternoon), so I moved emacsconf: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:
    - emacsconf:papers, emacsconf:project, emacsconf:org-teach, emacsconf:flp, emacsconf:color should be pretty general
    - emacsconf:color and emacsconf:theme are both theme-related. emacsconf:color needs to be in the morning and emacsconf:theme needs to be in the afternoon, so I put them on either side of the lunch break.
    - Other afternoon talks: emacsconf:water and emacsconf:shell are by the same speaker. emacsconf:casual, emacsconf:hyperdrive, and emacsconf: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 emacsconf: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:
    - emacsconf:gypsum, emacsconf:rust, emacsconf:julia, emacsconf:guile, and emacsconf:mcclim are about other projects
    - emacsconf:graph, emacsconf:p-search, emacsconf:secrets, and emacsconf:repro will probably be more dev-focused
- 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: emacsconf:students, emacsconf:links, emacsconf:regex
  - emacsconf:blee and emacsconf:language are probably general-audience
  - emacsconf:pgmacs, emacsconf:regex, and emacsconf:transducers are all development-oriented, but are on the general track for scheduling purposes. [[emacsconf:transducers]] can only be on Sunday afternoon at 4pm because of availability.
  - I've separated emacsconf:hyperbole and emacsconf:hywiki by lunch so that people who are interested in that can attend the live Q&A for both without worrying about missing things.
  - emacsconf:learning, emacsconf:sharing, emacsconf:literate will probably be good for a general audience

:PROPERTIES:

:END:

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
- [[https://sachachua.com/blog/2023/12/emacsconf-backstage-figuring-out-our-maximum-number-of-simultaneous-bigbluebutton-users/][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, monthly USD 144 - meets minimum requirements and can probably support 200 simultaneous ([[https://docs.bigbluebutton.org/support/faq/][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 - [[https://docs.bigbluebutton.org/support/faq/#what-is-the-disk-space-usage-for-storing-one-hour-of-recordings][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.

- 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?
  - https://bigbluebutton.host/plans/#economyplans - Economy 120 (USD 130/month) or Economy 80 (USD 85/month), custom URL
  - https://www.bigbluemeeting.com/#pricing - 100 concurrent users: USD 125/month, custom URL
  - https://www.mynaparrot.com/affordable-bigbluebutton-hosting
    - 100 concurrent users: USD 79/month
    - 200 concurrent users and custom URL: USD 15 setup fee + USD 149/month
  - https://www.webhostingzone.org/solutions/bigbluebutton-hosting.html - 150 concurrent, USD 75/month
  - https://bbbplugin.com/en/pricing/bigbluebutton-for-api/ - 250 concurrent, USD 49 setup + USD 108.80/month
  - https://biggerbluebutton.com/plans
    - 150 concurrent users, 10 concurrent meetings, USD 40/month
    - 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
    - [2024-11-13 Wed] 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
- Galene?
  - [2024-10-31 Thu] 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.
