:END:
We're now in the harvesting phase of the conference, where we work on
collecting the ideas that people shared in the Q&A sessions as well as
any talks that were not available as pre-recorded videos. It's a great
way to help speakers get stuff out of their heads and into a form we
can all learn from. =)
Status of talks and Q&A sessions:
- All talks except for the new version of grail should now be
available at https://media.emacsconf.org/2022/ and on talk pages
- Links to the BBB playbacks and to the various BBB resources (--bbb-*
for each talk) are now in the backstage area for speakers and/or
volunteers to review
- RMS Q&A audio has been uploaded (--questions.ogg)
- grail talk will be reuploaded by the speaker
- IRC logs have been copied to the backstage area; see the links at
the top of the backstage area
- Etherpads have been converted to Markdown and included on the talk pages
- BBB chats have been converted to Markdown and included on the talk pages
Here's a good/better/best scale for stuff we can do during this phase:
- Good:
- Look at IRC log at the top of the backstage area and copy
anonymized questions/answers/feedback to the wiki pages as well,
if they weren't already on the page
- Somewhat manual because of overlapping conversations; might be
easier to have one volunteer do all the talks in one shift
(Saturday morning gen, Saturday morning dev, Saturday afternoon
gen, etc.), so you can e-mail to call dibs if you like. We
usually remove names from the public log as well. Most of the
conversations should be in the track-specific channels, but some
might have ended up in #emacsconf as well. You can check the
talk page to see if the questions are already there. If you're
already set up to edit the wiki or you can figure out the
slightly complicated setup for editing, feel free to edit the
page directly. If not, you can email a Markdown or Org Mode
snippet to emacsconf-submit@gnu.org and let me know what page to
put it on.
- Better:
- Review the BBB recording to check if there's anything that needs
to be deleted from the recording before we publish it so that
people can listen to things themselves; publish the recording or
excerpts of it
- Might be easier with the transcript, but can also be done
without one. asmblox, async, buttons, dbus, detached, and eshell
have --bbb-webcams.vtt as the autogenerated Whisper transcripts.
- Even better than that:
- Make chapter markers for the Q&A recording so that people can jump
to the question they're particularly interested in. You can write
them in the form:
mm:ss text goes here
mm:ss more text
and I can turn those into chapter headings.
- Totally awesome:
- Edited captions/transcripts for the Q&A
- Answers copied into the Q&A section, possibly with linked timestamps
**** Process for reviewing and trimming the videos
Helper function:
- emacsconf-extract-publish-qa (call with C-u in order to specify a time for truncating the video)
Skim the transcript and the videos to see if anything needs to be removed, and which video to use
BigBlueButton gives us the webcams and audio as one video
(`--bbb-webcams.webm`) and the screenshare (if any) as another video
(`--bbb-deskshare.webm`). If the speaker shared their screen, we can
focus on that instead of their webcam. The following ffmpeg command
combines the audio from the webcams (which has been previously
extracted into a separate file, `--bbb-webcams.opus`) with the video
from the screenshare.
ffmpeg -i example--bbb-webcams.opus -i example--bbb-deskshare.webm -c copy example--answers.webm
We also want to check if people accidentally shared sensitive
information on their screen, or if anyone said something that they
might not have said if they remembered that the the Q&A videos will be
shared after the talk. Sometimes there's some time before we get
around to closing the meeting at the end of the Q&A. Usually, a quick
read of the transcript will show anything that needs to be trimmed.
Here's how to stop the recording at a specified time:
ffmpeg -i input.webm -to hh:mm:ss -c copy output.webm
Cutting out stuff from the middle of a recording is slightly more
complicated. It might be easier to use a nonlinear video editor such
as kdenlive to edit the video. If you want to use ffmpeg, using
filters to select the frames and reencode the video will probably work
out better than splitting the file into multiple parts and then
concatenating them without reencoding, as the latter tends to need to
be split on keyframes. Here's a sample command based on this
[StackOverflow](https://stackoverflow.com/questions/64866231/remove-a-section-from-the-middle-of-a-video-without-concat) answer that removes the section between 15 seconds and
45 seconds:
ffmpeg -i input.webm \
-vf "select='not(between(t,15,45))', setpts=N/FRAME_RATE/TB" \
-af "aselect='not(between(t,15,45))', asetpts=N/SR/TB" \
output.webm
Alternatively, you can let us know what parts needs to be trimmed, and
we can figure that part out.

There were lots of interesting notes and Q&A on IRC and the pad. If we can copy them to the talk page on the wiki, then we can catch any questions that hadn't been answered and forward feedback to the speaker. It's a little challenging because the IRC conversation might get mixed up when another talk starts, so it helps to read the IRC log and decide what lines to include. We usually remove names from the public log as well. Most of the conversations should be in the track-specific channels, but some might have ended up in #emacsconf as well.
I've added IRC chat logs to the top of the backstage page. Each talk also links to the HTML (--pad.html) and Markdown (--pad.md) version of the pad.
You can see the 2021 talks (ex: https://emacsconf.org/2021/talks/frownies/ , https://emacsconf.org/2021/talks/pattern/ ) for an example of how the discussions were archived on the talk pages. Sometimes we organize them by type of comment, so it's easy to see Q&A vs. notes vs. feedback about the talk itself.
To avoid duplicating work, maybe we can use this Etherpad to call dibs on talks to process. You can write your name or nick next to the talk(s) you're archiving.
If you're already set up to edit the wiki or you can figure out the slightly complicated setup for editing, feel free to edit the page directly. If not, you can email a Markdown or Org Mode snippet to emacsconf-submit@gnu.org and let me know what page to put it on.

aaaaaah, hmm. recording timestamp seems earlier, that might just be when BBB starts the whole thing.
aha! The raw directory has the whole thing, not just the recorded part, and the recording timestamp is the beginning of the meeting. So let's find out where the actual recording starts.
Maybe StartWebRTCShareEvent ?
ParticipantStatusChangeEvent might be the webcam start.
Is it DeskShareStartRTMP ?

Hi, ${speakers-short}!
Thank you so much for being part of EmacsConf ${year}! Hundreds of
people enjoyed it, and I'm sure even more will come across the videos
in the days to follow.
Your ${video-is} available on the talk page${plural} at ${urls} , and
we've added the discussions from Etherpad/IRC.${bbb-note}${wrap}
We've also uploaded your talk video${plural} to Toobnix (a PeerTube
instance) at ${toobnix-url} and YouTube at ${youtube-url} . If you
want to reupload the video to your own channel, please feel free to do
so. If you let me know where you've uploaded it, I think I can switch
our playlist to include your version of the video instead. That way,
it might be easier for you to respond to comments on videos.${wrap}
If you would like to share more resources, you can add them to the
talk page or e-mail them to us and we can add them for you.
Thanks again for speaking at EmacsConf!
Sacha

If it was announced in the last 5 minutes, don't reannounce it as part
of the hook, but allow reannouncements if called manually.
How to detect announcements:
If it was the most recently announced talk in the channel, don't re-announce it

:END:
Summary:
- bandali will stream from his computer; confirmed can stream to dev
- corwin will probably connect to gen by VNC; confirmed can connect to VNC and click around, need to become more familiar with setup after trip
- sachac will be backup streamer if bandali or corwin are unavailable
Goals:
- Good: Streamers are set up to broadcast from their own OBS if needed (could be a backup plan, could be the main plan)
- Better: Streamers can connect to the VNC session for their track, manage OBS, start videos (with overlays), and browse the Q&A links
- Best: Streamers can connect via emacsclient in orga@res.emacsconf.org, manage the task status, and have everything working
Agenda:
- Get familiar with the setup
- Consider whether we want to prioritize local OBS (more screen real estate) or stream OBS (easier swapping, can be controlled remotely)
- Consider whether we want mumble to be able to quickly add audio; how do we want to set it up scene-wise?

**** Template
We plan to use Mumble as a virtual walkie-talkie during the conference
so that we can quickly talk to each other as needed. It can also be a
way for us to add our audio to the streams. Please set up your system
as follows:
1. Install a Mumble client on the device you want to use to connect to
the voice channel. It can be your computer or phone. You can choose
the username that you would like to log in with.
2. Create and backup your certificate. (This is part of the wizard for
the desktop client, and it might be automatic on a phone client.)
3. Connect to mumble.emacsconf.org with your desired username.
4. Register your account on the server using the ~Self > Register~
command. This reserves your username using your certificate and
allows me to add you to ACLs.
5. Let me know (sachac on #emacsconf-org in IRC or
sacha@sachachua.com) when you've registered so that I can add you
to the access control lists for the private channels. If I'm around
on mumble (sachac), you can say hi to me there and confirm that
it's working.
You can enter a channel by double-clicking on it. (On Mumla for
Android, entering a channel is instead done by clicking on the arrow
to the right of the channel.) Then your audio will go to that channel,
and you can hear audio from that channel. We can use the
~emacsconf-gen~ and ~emacsconf-dev~ channels to speak on air, and we
can use the ~backstage~ channel for coordination.
Looking forward to hearing from you!

- Opening remarks Sat
- Welcome to EmacsConf 2022
- What's new at EmacsConf?
- This year, we have two tracks: General and Development.
- Prerecorded videos will be published as soon as possible (aiming
for publishing them as the talks stream), so you can check the
talk page for the video and the transcript a few minutes after the
talk starts.
- How to participate
- You can watch at live.emacsconf.org using free and open source software.
- Select the stream you're interested in.
- There are quick shortcuts on the watch page so that you can
open the Etherpad, Q&A, or IRC.
- We recommend adding notes asking questions in the Etherpad
for the talk. That way, it's easier to organize the
questions and answers, and the host can read questions out
to the speaker as needed.
- You can also use the track-specific IRC channels
(#emacsconf-gen and #emacsconf-dev).
- You can look at the schedule to see what else is going on.
- IRC:
- You can use #emacsconf for hallway conversations.
- If you need to reach conference organizers, you can use the
#emacsconf-org IRC channel or e-mail sacha@sachachua.com .
- General feedback in pad.emacsconf.org/2022
- Accessibility
- Streaming with open captions thanks to speakers and volunteers
- Talks indicated with "captioned" on the schedule
- Transcript available on talk pages
- Encourage people to add notes, questions, and answers to the
Etherpad, which will be archived as plain text on the talk
pages after the conference
- If you need additional support, ask in #emacsconf-accessible or #emacsconf-org
- Closing remarks Sat
- Thanks

- [[https://community.jitsi.org/t/tutorial-etherpad-integration-in-jitsi-meetings/99697][Etherpad integration in Jitsi ]]
- Good: One pad per session
- Better: Some kind of monitoring so that we can link to the pads or embed
the pads even before the conference starts while not risking too
much vandalism
- Best:
- Pad can be easily regenerated from Emacs Lisp with a check to see if people have been adding to it
- Pad links to next talks
Where should we host this?
- live0: gets scaled up the most, lots of people connect to it for the conference, didn't hit performance constraints last time
- front0: lower risk of interfering with stream
- bbb: will already be put on strain with the concurrent streams (test showed it was stable with up to 10 concurrent video streams and 40 total participants)
- opal’s: no news from owner, but beefy server that we used for reencode last year
- new Linode (probably 4GB or 8GB shared CPU): can easily be spun up, yay Ansible
[[#ansible][Ansible notes]]
Consider if we need extra scaling beyond being on a beefy live0?
- Scale calculator: https://scale.etherpad.org/
- assuming 3 concurrent authors, 100 lurkers per pad, 3 concurrent pads
- 1 core, 4GB RAM, bandwidth Mb/s: 7.488
- https://mclear.co.uk/2021/09/08/deploying-etherpad-at-scale-in-one-minute/
- https://github.com/ether/etherpad-load-test
Will need to try this again when we resize nodes. Probably just the extra memory will be enough and the CPU use from node won't step on the streaming, but not sure

tl;dr: Either a separate 4GB Linode or being on live0 will probably be
okay, but I'm not 100% sure due to the limitations of my load-testing
setup. I don't know if we need to shard by pad.
It looks like etherpad-load-test tends to max out at ~40 connections
on a specific node. I used GNU Parallel to run the loadtesting tool
against a 4GB Linode instance (shared CPU) from five nodes at the same
time (my X220, my 2GB Linode instance, front0, and the node with the
pad), and they all reached about 35-45 clients before failure (not
updating within 100ms).
#+begin_src sh :eval no
echo 'node node_modules/etherpad-load-test/app.js http://170.187.195.5:9001 -d 120 > ~/output.txt' | parallel -J loadtest -j 1 --onall --verbose --tag

:end:
Files were created at roughly the same time, so the max loads probably
overlapped. It would be good to have finer control over the
etherpad-load-test tool. Haven't figured out how to properly use ~-l~
and ~-a~ yet.

*** #EmacsConf behind the scenes: Testing the schedule with SVGs
#+begin_quote
Org mode allows you to have inline images, and you can return them as the results of Org Babel
blocks. I wanted to test different #EmacsConf scheduling strategies quickly. I used Emacs's XML and
SVG support to create the SVGs based on the scheduling data I gave it. Splitting my window made it
easy to change the schedule, use `C-c C-c` to execute the block, and see the schedule image
(including any validation notes) in the other window. The code is in
https://git.emacsconf.org/emacsconf-el/tree/emacsconf-schedule.el .

jotaemei@social.coop - @sachac I like this idea of a timezone converter for people displayed on (or by) the listing. For me, the cause was that I was trying to find my way around the site at the last second and was afraid I’d missed a presentation I saw someone post earlier about coming up, but I think it was just that the speakers were running a little behind schedule.

** Do we want to drop talks?
:PROPERTIES:
:CUSTOM_ID: drop
:END:
- *Keep the slot open, allow people to speak live*
- If they don't show up, continue with previous Q&A or have an open room
** How do we want to coordinate during the conference itself?
:PROPERTIES:
:CUSTOM_ID: coordination
:END:
- Considerations:
- Good to have something that the hosts and streamers can walk through step by step
- Do we want the check-in volunteer to also keep something
- Announcing and publishing are easier if the task states are updated
- Mumble for walkie-talkie communications?
- Can we keep it off the stream more reliably, but still be able to choose to put it on the stream?
- We can keep it in the combined sink and then manually go to that
channel in our clients when we want to talk on stream
- Should we have a Gen channel and a Dev channel so that we can choose to speak into ?
- Checklist
- Etherpad
- All the volunteers can access it easily
- Tasks can be updated through SSH commands
- conf.org
- Run Emacs commands directly from it
- A little trickier in terms of access
** How do we want to make the full schedule more manageable?
:PROPERTIES:
:CUSTOM_ID: sched-decision
:END:
Host role:
- Give the speaker a heads-up before their Q&A session begins
- If needed, read the questions from the pad to the speaker (Many speakers are comfortable reading the pad on their own.)
- Give the speaker time warnings before the end of their Q&A session on the stream. Interested participants can continue
Streamer role:
- Switch between playing the prerec and joining the Q&A session
- Adjust audio volume at the beginning of the Q&A session
- (optional) Switch scene layouts to focus on different things
Shifts will be Sat AM, Sat PM, Sun AM, or Sun PM per track. People can take multiple shifts.
https://emacsconf.org/2022/decisions/#schedule
- Figure out how hosting can be done in shifts
- Add notes in one place
- Figure out how streaming can be done in shifts: OBS in the cloud?
- [[*Investigate streaming options, maybe OBS in the cloud][Investigate streaming options, maybe OBS in the cloud]]
- Figure out how publishing can be done in shifts
- Console Emacs in a VM with everything set up for publishing to the wiki
[2022-10-04 Tue]
- Added option H: general starts with general Org use cases and moves on to more niche things on day 2.
- compared to A, general audience will be more interested in Org use
cases than in Hyperbole, and then we can look at specific
techniques on day 2
[2022-10-04 Tue]
- Discussed option G with zaeph on #emacsconf-org. zaeph prefers
option A over option G because it gives people more choices -
they can hop from talk to talk.
[2022-10-03 Mon]
- Discussed with bandali and zaeph on #emacsconf-org
- Decided on Option A with B, C, or F as fallbacks depending on volunteer roster
- Better for the viewers and the volunteers
** Do we want to skip the closed Q&A and go straight to open?
:PROPERTIES:
:CUSTOM_ID: closed
:END:
- Closed: Less moderation needed in the beginning
- Open: less coordination needed (since the host doesn't have to either tell me that it's okay to open it up or change the task status themselves), and people are generally good at meeting etiquette
** How much do we want to enrich the wiki with JS?
:PROPERTIES:
:CUSTOM_ID: wiki-design
:END:
Ideas to consider:
- Toggling local time display on the schedule
- Making organizers-notebook nicer to browse through (or maybe use organice?)
- Improve the video player (resolution switching? chapter markers?) - https://github.com/sampotts/plyr for video?
*** SOMEDAY [#C] ?: Figure out JS and CSS niceties that will make organizers-notebook more enjoyable to browse through :css:js:
- TODO/DONE/etc. keyword highlighting?
- Collapsible sections?
*** SOMEDAY [#C] ?: Find a way to add JS libraries to the wiki but shield them from anon editing :js:
gitolite should have some options to do this
*** SOMEDAY [#C] ?: Beautify video players :js:css:
Might not be necessary.
** How do we want to make better use of Etherpad?
:PROPERTIES:
:CUSTOM_ID: pad-decision
:END:
Pain points:
- Lots of scrolling for speakers
- Takes some effort to move questions from IRC to the pad
*** How many pads do we want?
- One pad for everything
- Scroll down, down, down
- Easy to set up at the beginning
- Inertia
- One pad per set of talks (Saturday AM, Saturday PM, Sunday AM, Sunday PM)
- Less scrolling
- One pad per talk, plus one meta pad
- Very little scrolling
- Can send people directly to the pad
*** Do we want to host our own?
- Use etherpad.wikimedia.org
- Worked fine last year
- Host our own
- Might be able to use API to append questions to it, if we want to get super fancy
*** Do we want to embed the pad as an iframe on the watch page? on talk pages?
This guides people to use the pad for discussion/questions instead of IRC
Options:
- Current: None, just a link
- Big pad on the watch page:
- Individual pads:
- Watch page needs to be updated with current pad and link to previous pad
- Individual talk page can embed the iframe
- Embed the IRC channel instead
** Can we nudge people to ask IRC questions in a way that will make it easier for us to follow them?
:PROPERTIES:
:CUSTOM_ID: irc-markers
:END:
Two tracks mean two IRC channels with lots of space for Q&A, so this may become less of an issue
Pain points:
- Q&A/discussions often overlap with the next talks
- Sometimes questions don't get copied to the pad
- Fast discussions can get overwhelming
Ideas:
- Announce pad link at the beginning of the talk and at the start of
live Q&A, encourage most people to ask questions there
- Encourage people to start questions with Q:
- A little extra work, but not as much as including the slug
- Easier to pick out when people search
- Volunteers can restate questions easily if people forget the Q:
- Encourage people to start questions with Q-slug: (ex: Q-news: question about Emacs News Highlights, Q-journalism: ...)
- Easier to pick out questions even with overlapping Q&A/talks
- Use two or three IRC channels so that talks can rotate among channels
- Easier to pick out questions even with overlapping Q&A/talks
- Needs logging and more organizer attention
- Maybe a volunteer can have an ERC command that copies a question into a buffer, or even into the Etherpad
** Do we want people to advertise any openings with their companies or any work that they're looking for?
:PROPERTIES:
:CUSTOM_ID: advertising

*** Where should volunteers e-mail?
:LOGBOOK:
- Note taken on [2022-09-23 Fri 11:26] \\
Discussed in #emacsconf-org
:END:
- *Default to emacsconf-org and offer emacsconf-org-private as an option*
- emacsconf-org-private
- less public, e.g. if for whatever reason we might have to decline an offer of help
- Also, some people want to volunteer but do not want to be in the public’s eye.
- emacsconf-org
- If you’re thinking about the enticement factor of having people
volunteer publicly, we’ll still have a well-furnished list of people
helping us run the conf somewhere on the wiki. [11:22]
- i would think if someone doesn't want to do it publicly, they could
opt to write to -org-private instead, but otherwise the defacto
should be public (-org)
- i just think most folks would want to do this publicly unless for
specific reasons, rather than the other way around
*** CANCELLED Do we want to do alt-stream the same way again this year?
Superseded by decision to have multiple tracks
- Alt stream joins the current session and then continues with it until the Q&A finishes; people join the BBB room if they want to ask questions
- Nice and convivial, Q&A still gets captured
- Inertia means most people get the main message
- Multiple streams with more space between talks, people choose which stream they want to watch
- How other conferences do it
- Speakers can attend related talks more easily
*** DONE Shall we put a generic e-mail address for sending feedback, maybe with different mailtos?
CLOSED: [2022-10-07 Fri 14:45]
Pain points:
- Many talk pages don't have public e-mail addresses, so it takes a
little extra work (or is sometimes impossible) for people to follow
up if they have questions
Options:
- Do nothing (current)
- Add a mailto link to emacsconf-discuss that prepopulates the subject
- Add a mailto link to emacsconf-org
- Wider discussion
- *Add a mailto to emacsconf-org-private*
- Private feedback that can be forwarded to the speaker
*** DONE How many BBB rooms do we want to set up?
:PROPERTIES:
:CUSTOM_ID: bbb-rooms
:END:
- One per talk
- We can send speakers a direct link to their room and they can check into it themselves
- Needs a little more work when setting up rooms and when extracting videos
- Easier for the host to join
- Check-in person can just keep an ear open in that room
- Five or so, rotating among them
- Check-in person directs the speaker to the next available room
- Worked fine last time
*** DONE How easy do we want to make it to join the BBB session?
:PROPERTIES:
:CUSTOM_ID: bbb-join
:END:
Considerations:
- It's easier for the checkin person to deal with only the speaker
- We may not want people to join the Q&A session at the beginning
- We want to make it easy for people to join the Q&A session eventually
Options:
- PROBABLY EASIEST: Set it to anyone can join, but the meeting needs to be started by a
moderator. Start the meeting on the day of the talk. Announce the
BBB URL in the pad, IRC channel, and on the talk page when the host
is ready. Maybe add a rewrite rule when the host is ready.
- Set an access code. Announce the access code when the host is ready.
- Access codes are annoying to copy and paste.
- Access codes might get accidentally unset or regenerated.
- Set room so that moderators have to approve waiting users.
- Check-in has to watch out for waiting speaker.
- Host sets it to accept everyone who's waiting when the host is ready.
- Changing it to turn the option off doesn't seem to affect an
ongoing meeting, even though the web interface says you should be
able to change the setting any time.
- Waiting users don't make the user notification go ding.
Change talk status to OPEN_Q or UNSTREAMED_Q, and change to TO_ARCHIVE when done.

Needs to be easy to:
- share all the BBB rooms for a particular shift with the check-in volunteer
- start the BBB rooms for the morning
- match up the recordings with the talks afterwards
- find the BBB room for a talk or speaker
- remove all the BBB rooms for the year

- Speakers and general public will be able to edit it more easily
- Git: (current)
- Haven't had a problem with spam
- Reduces merge conflict potential

:PROPERTIES:
:CUSTOM_ID: roles
:END:
Each role comprises different responsibilities. A person may have multiple roles. An organizer might take the lead for a role, but if you want to volunteer, speak up and they'll probably be glad to share the load.

This can only be done by the admins of the gitolite instance (zaeph,
or bandali as a backup). This is because the changes need to be made
in the gitolite-admin repo that can only be accessed by admins. In a
pinch, people with access to the `orga` user on front0 can manually
add themselves to the list of admins and manually rebuild the
instance.
Regular process:
- Get public key from volunteer,
- Add key under ~./key/dir/~,
- Update permissions on ~./conf/gitolite.conf~,
- Push to origin.

${minutes} minutes long (${time} minutes budgeted).
We'll be working on captioning it over the next few weeks. We'll
e-mail again a little closer to the conference with schedule updates
and other useful information. If you want to upload a new version, you
can upload it the same way you did the previous one.
Please feel free to e-mail us at emacsconf-submit@gnu.org if you need
help updating the talk wiki page at ${url} or if you have other
questions.
Thank you so much for all the work you put into preparing a talk for
EmacsConf ${year}, and thank you for submitting the prerecorded video
before the conference!

*** Mastering the prerec’s audio-track
:PROPERTIES:
:CUSTOM_ID: mastering
:END:
Mastering is the process of preparing an audio-track for a purpose. For
us, the purpose is quite simple: maximize the intelligibility of the
speaker and minimize the noise.
We can get great results with Audacity for the vast majority of
audio-tracks. Sometimes, however, some audio-tracks have intractable
noise-profile that require the use of model-based denoising filters that
can applied with ffmpeg.
We’ll start with the average Audacity workflow, and we’ll move on to the
model-based filters after.
**** Audacity workflow
When we process a prerec, we extract the audio of the original upload
and add it to the backstage. You should be able to find it under the
name --original.$audio_format or --main.$audio_format. If it’s not
there, it’s easy to extract the audio from the original video, but
we’d prefer if you warned core-organizers about it because it’s not
normal.
We’ve simplified the process down to these steps:
1. Open the audio file in Audacity.
You might want to increase the size of the waveform by pulling on the
bottom of the bottom of the track.
[[https://media.emacsconf.org/misc/audacity-demo-noise-reduction.webm][audacity-demo-noise-reduction.webm]]
2. Find a moment of quiet in the video, and select it.
We ask our speakers to include 5 seconds of quiet at the beginning or
end of their prerecs, but even if they don’t, it’s relatively.
3. Effects → Noise Reduction → Get Noise Profile
4. Select → All
5. Effects → Noise Reduction → OK
You can select a spoken portion of the track before applying the
effect and preview it to test your settings. The default are usually
enough (Noise reduction (dB): 12, Sensitivity: 6.00, Frequency smoothing
(bands): 3).
[[https://media.emacsconf.org/misc/audacity-demo-noise-reduction.webm][audacity-demo-noise-reduction.webm]]
6. Tools → Apply Macro → Alpha
Before you can apply the Alpha macro, you need to save its content to
disk and import it via Tools → Macro Manager → Import.
#+begin_src txt :eval no :tangle audacity-macro-alpha.txt
Reverb:Delay="20" DryGain="5" HfDamping="99" Reverberance="15" RoomSize="70" StereoWidth="25" ToneHigh="0" ToneLow="100" WetGain="-13" WetOnly="0"
Amplify:Ratio="1"
FilterCurve:f0="79.621641" f1="101.02321" FilterLength="8191" InterpolateLin="0" InterpolationMethod="B-spline" v0="5.9148936" v1="0.042552948"
Normalize:ApplyGain="1" PeakLevel="-3" RemoveDcOffset="1" StereoIndependent="1"
Compressor:AttackTime="0.1" NoiseFloor="-50" Normalize="1" Ratio="2" ReleaseTime="1" Threshold="-30" UsePeak="0"
#+end_src
7. Export → Export Audio… → Opus Files (.opus format)
Use the following settings:
[[https://media.emacsconf.org/misc/audacity-export-settings.png][audacity-export-settings.png]]
#+begin_quote
Bit Rate: 64 kbps

Compression: 10
Application: Audio
Frame Duration: 20 ms
Cutoff: Disabled
#+end_quote
**** Model-based denoising filter
If you can’t manage to get a good result with Audacity, chances are it’s
because there’s too much noise in the video, even after profile-based
denoising. This usually happens when the noise-pattern of an
audio-track evolves over the video, or if has an aperiodic quality. For
those, we’re going to need a bigger boat.
Model-based denoising means using an AI-generated model to remove the
audio frequencies that are usually associated to noise and preserve
those that aren’t. A different context (e.g. noisy room with statics,
noisy room with people chatting, etc.) means a different model; for us,
this means a model that minimizes background noise and maximizes clear
voices (the speakers’).
This is the model we’ve been using:
[[https://media.emacsconf.org/misc/audio-denoiser-model-mp.rnnn][audio-denoiser-model-mp.rnnn]] (download link)
Source: [[https://github.com/GregorR/rnnoise-models][rnnoise-models]], Model: [[https://raw.githubusercontent.com/GregorR/rnnoise-models/master/marathon-prescription-2018-08-29/mp.rnnn][marathon-prescription]]
You should always apply the filter on the original’s audio, as opposed
to an Audacity-processed audio. This is to ensure that we have the most
information about the signal, which means we can have gather the most
information about the noise-profile.
Following is the ffmpeg incantation to use to apply the filter-model.
Make sure to modify the ~DENOISER~ variable and adapt input/output.
#+begin_src sh :tangle audio-denoiser.sh :eval no
DENOISER="/path/to/audio-denoiser-model-mp.rnnn"
input="original.opus"
output="denoised.opus"
ffmpeg -i "$input" -af "arnndn=m=$DENOISER" "$output"
#+end_src
There’s no need to customize the libopus export information; the default
is more than enough for human-speech.
When you’re done with this step, you can then process the outputted
audio-track with Audacity, skipping the denoising steps (1 to 5).

If you’ve got any question on the process, you canget in touch with me (zaeph)!

FFMPEG process for sending the desktop and audio to the $CONFALT mountpoint on Linux with X11 and Alsa:
1. Set the CONFALT environment variable to icecast://user:password@live0.emacsconf.org:8000/alt.webm
2. Install pavucontrol if you don't have it already.
3. Start the following command ([[file:stream-desktop-and-audio.sh]]:
#+begin_src sh :eval no :tangle stream-desktop-and-audio.sh
while true; do ffmpeg -loglevel 0 -ar 48000 -f alsa -channels 2 -sample_rate 48000 -i default -re -video_size 1280x720 -framerate 25 -f x11grab -i :0.0 -cluster_size_limit 2M -cluster_time_limit 5100 -content_type video/webm -c:v libvpx -b:v 1M -crf 30 -g 125 -deadline good -threads 4 -f webm $CONFALT; done
#+end_src
4. Use pavucontrol to set the recording source for the ffmpeg
command to be the audio monitor, so you get system output as
well.
- OR:
- [? splitting audio] (look for “Set up sinks for sound” under 2021/)
- [? same audio]
- Set up audio monitor as the input for FFMPEG
- MPV goes to MPV sink, browser goes to recording sink, FFMPEG takes in recording monitor

Here's the tentative schedule for when your EmacsConf talk${plural}
will be streamed. Your talk${plural} will be streamed once, but I've
included a few timezone conversions for convenience.

${availability-note} You'll also have time for Q&A afterwards, which
can be as short or as long as you like. We'll send you more
information about how the Q&A will work as the conference gets closer.
If you'd like to see the other talks for context, you can check out
the draft schedule at https://emacsconf.org/${year}/draft-schedule/ .
The times may move around a bit as we update the schedule, so I'll
check in with you if things change a lot. ${coordination-note}
We'd like to publish the schedule this month, so we'd love to hear
from you by *${reply-by}* if the times don't work for you. (We can
shuffle things around even after that date if something comes up.)
Also, if you think your talk${plural} would go better next to a
different talk, please let us know. ${timezone-note} Please keep
emacsconf-submit@gnu.org in To or Cc when replying. Thanks!

Hi ${speakers-short}!
I tweaked the schedule to allocate a little more time for the meetups
talk, and I moved the buddy talk earlier to make space. I think this
might improve the flow as well, since the meetups will refer to how
meeting up with a buddy is a good way to get a public Emacs meetup off
the ground. If you'd like to see the latest schedule for your talk,
you can go to https://emacsconf.org/${year}/talks/ . Thanks for your
patience!

Hello, EmacsConf volunteers!
We're starting to gear up for EmacsConf 2022, and we would love to
figure out how to work with your skills, interests, and availability.
<https://emacsconf.org/2022/volunteer/> has some specific task ideas and
general roles.
<https://emacsconf.org/2022/organizers-notebook/#overall> has an
overall prioritization matrix. If any of those options look like
something you want to learn or help with, or if you want to make
things even better than what's in the table, let me know.
Given the number of talks this year, we're going to try to see if we
can pull off two tracks. I've posted a draft schedule at
<https://emacsconf.org/2022/draft-schedule/> and have e-mailed speakers
to confirm their availability. This schedule staggers live Q&A
sessions so that the person managing the streams can jump back and
forth as needed. We'll figure out shifts once we've sorted out the
processes and training info, but if you want to call dibs on
something, feel free.
<https://emacsconf.org/2022/organizers-notebook/#shifts>
Please let me know what kinds of things you'd like to learn more about
or help out with!

Hello, folks! Here's the weekly update on what's happening backstage
for EmacsConf 2022 in case you notice something that you want to help
out with. =)
- All the speakers have confirmed that they've gotten the acceptance
e-mails. Many speakers have confirmed that the schedule works for
them after I reshuffled a few talks for better availability. I've
posted the schedule at https://emacsconf.org/2022/talks/ . We'll
announce the schedule on the emacsconf-discuss mailing, Reddit, and
various places this week.
- zaeph has been working on the ffmpeg incantations for preprocessing
the videos that will be submitted soon. bandali is working on
getting the FTP and web-based uploads sorted out so that speakers
can submit their videos.
- I created some watch pages to support viewing different tracks:
https://emacsconf.org/2022/watch/ . The livestreams won't work yet
and it would be nice to figure out something that can dynamically
display info for recent/current/upcoming talks, but it's a start.
- We set up a self-hosted Etherpad (ex:
https://pad.emacsconf.org/2022-journalism) with an easy way to
redirect to using Wikimedia in case we run into scaling issues. I've
added it to our Ansible playbook
(git@git.emacsconf.org:pub/emacsconf-ansible) and I'm looking
forward to incorporating Ry P.'s improvements. Karl Voit gave
feedback on the first draft of the template.
- vetrivln volunteered for some of the dev hosting shifts, Karl Voit
volunteered for some of the gen pad shifts, and FlowyCoder
volunteered for some of the gen check-in shifts. Thanks!
Next week, we hope to:
- Announce the EmacsConf 2022 schedule in the usual places (got any wording/JS/CSS suggestions?)
- Finalize the upload instructions so that speakers can start submitting their files
- Put together volunteer training materials
- Set up per-speaker BBB rooms and friendly URLs

zaeph: I can work on it, but I’m not experienced in this domain, so I’d prefer to be a back-up.
task is currently with bandali
Lesson learned from last year: "Since people kept running into ftp
problems, we might want to set up a web-frontend next year to minimise
problems."
Maybe we could ask some of the volunteers who wanted to help us with
the infra? It shouldn’t be complicated to deploy a ready-made
solution.
"file drop" is a common keyword for looking for information.
Considerations:
- Probably run it on media.emacsconf.org
- Bonus features:
- password-protected or hidden behind some kind of authentication or hidden behind some kind of URL, so we don't have to worry too much about spam
- extra points for sending speakers links to upload to specific folders so that we can separate resources by talk
- Resumable uploads would be good, since some speakers had a hard time with unreliable connections
- What other conferences do:
- LibrePlanet uses plain FTP and recommends FileZilla https://libreplanet.org/wiki/Video_upload_instructions
- FOSSDEM uses Pentabarf to receive uploads https://archive.fosdem.org/2022/manuals/program/speaker/
- DebConf uses SReview(?)
- FOSSGIS uses Seafile https://vmx.cx/cgi-bin/blog/index.cgi/video-uploads-for-an-online-conference%3A2021-06-12%3Aen%2Cconference%2Cgeo
- Some options:

| https://github.com/pomf/pomf | | | php+mysql | |
| https://github.com/psi-4ward/psitransfer | official | | node | can set upload password, resumable; data volume needs uid 1000 |

Hi, ${speakers-short}!
${prerec-note}Here are the instructions for uploading the
video${plural} for your talk${plural}. You can find the latest version
of the instructions at https://emacsconf.org/2022/upload/ . There are
two ways to upload your talk${plural} this year, so you can pick the
one that works best for you:
- Web-based: https://ftp-upload.emacsconf.org , password emacsconf
- FTP: host: ftp-upload.emacsconf.org, port: 21, username: anonymous
folder: upload-here
If you upload slides and other resources, we can include them on the
talk page when your talk goes live. If you happen to have a script or
a transcript, please include them as well (it’ll speed up the
captioning for us).
Please add a comment or start your filenames with the ID for the talk
that it's for: ${slugs}.
If you're still working on your talk, you might find the tips at
https://emacsconf.org/2022/prepare useful. In brief:
- at least 1280x720 resolution
- we recommend dark text on a light background, with enough contrast
to make it easy to read
- if possible, use a headset or external microphone to record audio
in order to minimize computer noise
- upload a separate 5 second recording of quiet or leave 5 seconds
of quiet at the end of your talk video so that we can process your
video for noise reduction
Please plan to upload your talk by November 4 (next Friday) so that we
can get started preparing it for streaming. If you can't make it by
then, we can accept later submissions, although it's a bit more of a
scramble and our stress levels go up as the conference approaches. =)
We'd really appreciate the extra time for captioning and
double-checking. Thank you for your help in getting ready for a smooth
EmacsConf 2022!

Hello, folks! Here's the weekly update on what's happening backstage
for EmacsConf 2022 in case you notice something that you want to help
out with. =)
- We've e-mailed the speakers instructions for uploading their files through either a web browser or an FTP client, and three speakers have already done so! Those talks are now available in the backstage area (https://media.emacsconf.org/2022/backstage/), along with the first set of edited captions (thanks Jai Vetrivelan!). If you don't have the username and password for the backstage area and you would like to access it, please e-mail me and I'll send you the details.
- We've created a BBB room for each speaker's live Q&A session. The URLs are in conf.org in the private repository if you need them.
- We've drafted some documentation for different volunteer roles. If you'd like to volunteer as a captioner, check-in person (hmm, reception?), Etherpad scribe, IRC monitor, or host, please check out the appropriate link and let me know if I need to add anything to the docs:
- https://emacsconf.org/2022/volunteer/caption
- https://emacsconf.org/2022/volunteer/irc
- https://emacsconf.org/2022/volunteer/pad
- https://emacsconf.org/2022/volunteer/checkin
- https://emacsconf.org/2022/volunteer/host
- Thanks to David O'Toole for signing up for some IRC shifts! If you would like to volunteer for a shift, check out https://emacsconf.org/2022/organizers-notebook/#shifts .
- We've updated our streaming configuration for the General and Development tracks, and have started testing them using mpv and the watch pages. Videos aren't currently streaming, but you can check out the layout of the watch pages at:
- https://emacsconf.org/2022/watch/gen/
- https://live.emacsconf.org/2022/watch/gen/
- https://emacsconf.org/2022/watch/dev/
- https://live.emacsconf.org/2022/watch/dev/
These pages could probably be a lot prettier and easier to use. If you have some ideas for improving them or if you'd like to work on the HTML/CSS/JS, we'd love your help!
- There are now Q&A waiting rooms with friendly URLs so that it's easier for people to join the live Q&A when the host decides it's okay to let everyone in. They're linked on the watch pages (along with the pads) and they'll be linked from the talk pages once we're ready to share them.
- zaeph has been busy tweaking the ffmpeg workflow for reencoding and normalizing videos. Thanks to Ry P. for sharing the res.emacsconf.org server with us - we've been using it for all the processing that our laptops can't handle.
- We experimented with using the OpenAI Whisper speech-to-text toolkit to create the auto-generated captions that captioning volunteers can edit. Looks promising! If you'd like to compare the performance between small, medium, and large models, you can look at the VTT files for the sqlite talk in the backstage area. I've also added support for tab-separated values (like Audacity label exports) and a subed-convert command to subed.el, which might give us a more concise format to work with. I'll work on getting word-level timing data so that our captioning workflow can be even easier.
Next week, we hope to:
- improve the prerec and captioning workflows
- get more captions underway
Lots of good stuff happening!

Hello, everyone! Here's the weekly update on what's happening backstage
for EmacsConf 2022 in case you notice something that you want to help
out with. =)
- Help wanted - Captioning: There are three talks open for captioning
in <https://media.emacsconf.org/2022/backstage/> , so feel free to
e-mail me if you'd like to reserve one. I've tweaked the captioning
process a little bit so that I can reflow the transcripts into
shorter subtitles before people edit the captions, so editing is
easier to do because you don't have to split along the way. (If
you're curious about the technical stuff, I switched to manually
splitting the text using emacsconf-reflow from emacsconf-el and then
the using aeneas for forced alignment, because I couldn't figure out
how to get torchaudio unstuck sometimes.)
If you don't have the username and password for the backstage area
and you would like to access it, please e-mail me and I'll send you
the details.
- Help wanted - tech checks: For sessions with live Q&A, we'd like to
set up tech-checks with speakers to make sure that their setup works
well with BigBlueButton. A rough outline of the process is in the
tech-checking protocol heading at
<https://emacsconf.org/2022/organizers-notebook/#tech-checks> . If you
would like to help with tech-checks, please e-mail us with your
general availability (including timezones) and preferred public
contact information so that we can include you on the list at
<https://emacsconf.org/2022/prepare/#tech-check> and in the e-mail to
speakers.
- Help wanted - intro/intermission slides, OBS overlay, ??: It might
be interesting to design something to show right before and right
after a talk so that people can see the title, speaker name, talk
page URL, Q&A info, pad URL, pronouns, etc. Ideally we'd be able to
generate a whole bunch of these from the talk data, so maybe SVG or
a TikZ picture? If this is your jam, let us know.
- OBS in the cloud: We've been able to figure out how to stream both
streams using OBS, VNC, and PulseAudio on Ry P.'s virtual server, so
it's even more likely that we're going to pull off two tracks this
year. Yay!
- Tom Purl has joined as a captioning volunteer. Hi Tom!
This week we hope to get lots of talks submitted, processed, and on
the way to being captioned. We're also planning to make the captioning
workflow even better, and to improve the OBS streaming workflow. Whee!

Hi everyone!
Here's what's been happening backstage.
- Speakers have been submitting their videos, hooray! I added a
schedule to the backstage page at
<https://media.emacsconf.org/2022/backstage/> so that people can see
how the schedule's coming along. We expect more talks to come in the
next two weeks. Not panicking yet. =)
- Thanks to all the people who've been working on captions so far!
Bhavin, Andrea, and Ramin did the captions for their talks, and Jai
captioned Bala's talk. Tom, Bhavin, and Hannah are currently working
on captions. There are three more talks backstage if anyone wants to
work on them.
- I just posted some notes on how I reflow and edit subtitles in case
they're helpful:
<https://media.emacsconf.org/2022/backstage/editing-captions.html>
It's also linked from the backstage page under More info: editing
captions.
- We added the Emacs development updates talk from John Wiegley and
updated the times of other talks based on messages from the
speakers.
- We did a dry run of the OBS streaming setup with Leo, Amin, and
Corwin. I think we're on track to being able to broadcast two
streams this year.
- IRC announcements, BBB redirection, and media file publishing can
now all automatically happen when the talk status changes,
simplifying our work during the conference. Video playback and Q&A
browser windows can happen automatically if streaming from
res.emacsconf.org. I want to get the publishing workflow all
smoothed out too, so that talks and transcripts can be more easily
published to the wiki pages during the conference.
Plans for this week:
- More videos and captions!
- I plan to work on talk page publishing so that it happens smoothly during the conference
- Leo's going to review the videos submitted so far and prepare intros for them
- Might be a good idea to reach out to speakers for tech checks and bios
EmacsConf is a little less than four weeks away. Stuff is happening!

:TO: emacsconf-discuss@gnu.org, emacs-tangents@gnu.org
:END:
Greetings, fellow Emacsians!
On behalf of the EmacsConf 2022 organizers team, I'm very excited to
announce the schedule for EmacsConf 2022 (Dec 3 and 4), available at:
https://emacsconf.org/2022/talks
All of the times listed on the schedule are in EST (UTC-5). You can
click on each talk's title to open its page for more information,
including its scheduled time in your local time. (Displaying local time
requires running a tiny bit of AGPLv3+-licensed free/libre JavaScript
code, included on the talk pages.)
For prerecorded talks, this time is also when the talk's video will be
made available on the same page. Please note that the times are
approximations, and that the schedule may change leading up to the
conference.
As the conference approaches, we'll post more details on how to watch
and participate.
You can subscribe to the emacsconf-discuss mailing list at
https://lists.gnu.org/mailman/listinfo/emacsconf-discuss to
be sure you'll get updates.
Want to help make EmacsConf even awesomer? Volunteer!
https://emacsconf.org/2022/volunteer/
We hope to see you all around on Dec 3-4 for EmacsConf 2022!
P.S. please direct all replies to this post either to myself or to the
emacsconf-discuss list, so as to help avoid generating extra off-topic
chatter in the other lists cc'd in this message; thank you.

Goals:
- Reassure people that they're in the right stream for the talk that they're looking for
- Direct them to the pad and Q&A for the talk
What to show in between talks:
- Previous talk: title, speaker, pronouns, talk page, Q&A information (if still live)
- Next talk: title, speaker, pronouns, talk page, Q&A information, countdown
https://media.emacsconf.org/2022/backstage/gen-in-between.pdf
https://media.emacsconf.org/2022/backstage/dev-in-between.pdf
- Good: Static image, maybe created with LaTeX
- Better: Video with unobtrusive sound so people can doublecheck that their audio works
- Best: Emacs thing so that we can have a dynamic timer and last-minute announcements, and so that it's Emacs =)
- Even better than that: A compact view that can be overlaid on the Q&A session using OBS
See break commercials
https://www.collabmagazine.com/organizing-a-multi-track-virtual-conference-with-microsoft-teams-live-events-a-technical-playbook-and-lessons-learned/
OBS scenes (maybe?):
- splash-screen when we’re on break
- scene when broadcasting a talk (where we might want a logo and a bar or surrounding to broadcast messages like time left in
recording); and
- Q&A scene with host-webcam, optional speaker-webcam, and pad with questions.
- Q&A scene focusing on shared screen from speaker
- Q&A scene with IRC and pad
Nothing is urgent, blocking it, or being blocked by it, so you can
play around with ideas.
We're experimenting with two tracks this year, so we expect that some
people will join midway through a talk or Q&A session and
would like to reorient themselves. Some Q&A sessions may end
early, so we would like to reassure people that they're in
the right spot for the next talk. Most Q&As will be done
live, but some Q&As will be done over IRC, so we need to
point people to the right place.
and if there's room for a little extra info like public e-mail
addresses or pronouns, that can help people when they discuss
things. That info will be in the pad and IRC, though, so it's
also okay to omit it
We can programmatically replace strings in
SVG from Emacs, so we can easily use that as an overlay.
<zaeph> …Or, if you just want to focus on the look of
things, we can think of the content on our own.
<sachac> oh yeah, totally, you can just focus on the design and use
placeholder text
Overlay considerations:
- talk videos will likely have subtitles; no subtitles for Q&A
- zaeph doesn't like vertical text

:CUSTOM_ID: streaming
:END:
Current status:
- res.emacsconf.org seems to be able to handle 2x (OBS + TigerVNC + MPV, should test with Firefox as well)
- corwin and jman will stream gen from OBS on res
- bandali will stream dev from his laptop
- let sachac know if you want manual control or more autopilot for the gen stream
Goals:
- [X] Be able to start a VNC server with OBS, MPV, and Firefox, connect to it, and stream
- [X] Have another session with the sound isolated
- [-] Split the audio so that we can join the Q&A room before the MPV ends - handled by automatic scene switcher detecting mpv, but we can't share just a window, so we might as well just wait
- [X] Control MPV from the commandline: track-mpv appears in the correct display, and it can also be controlled via the socket like this: echo '{ "command": ["loadfile", "test2.webm"] }' | socat - ~/mpv-socket-emacsconf-dev
- [ ] Share the window instead of the desktop?
Prerequisites:
- You need to be able to SSH out to res.emacsconf.org on port 46668
and forward ports, so one of the main organizers needs to add your
SSH public key to the authorized_keys file. Please e-mail your SSH
public key to sacha@sachachua.com and test that port 46668 is not
blocked.
- For streaming from OBS in VNC, you will need a VNC viewer like
tigervnc-viewer.
- For streaming from your local computer, you will need OBS and FFmpeg.
During the conference, you will:
- play the talk video (unless it's automatically managed by the agenda) and update the overlays
- display intro/intermission information as needed
- open the Q&A windows, like the pad and the BBB room/IRC (unless it's automatically managed by the agenda)
- adjust the volume if needed
- arrange windows and focus the BBB room on the speaker's webcam if needed
- if you like, you can be responsible for managing the track from conf.org on orga@res.emacsconf.org
Dry run checklist:
- [ ] Connect to the server
ssh orga@res.emacsconf.org -p 46668
emacsconf # runs emacsclient -c -a emacs
- [ ] Forward ports and connect via VNC
- [ ] Find the OBS or start it if it is not running
- [ ] Start recording
- [ ] Play a video
- [ ] Open two Firefox windows and arrange them
- [ ] Manage windows on the workspace
- [ ] Adjust the volume in OBS
- [ ] SSH to the server and play a video off-screen
- [ ] SSH to the server with X forwarding and adjust the volume off-screen
*** Broadcasting from local OBS (option A)
- You can copy the profile from your track or look inside it for the icecast mount point details:
- Gen: rsync -avze 'ssh -p 46668' emacsconf-gen@res.emacsconf.org:~/.config/obs-studio/basic/profiles/ ~/.config/obs-studio/basic/profiles/
- Dev: rsync -avze 'ssh -p 46668' emacsconf-dev@res.emacsconf.org:~/.config/obs-studio/basic/profiles/ ~/.config/obs-studio/basic/profiles/
- Sacha will turn off the OBS recordings on res so that you can test streaming from your computer
- If you're doing this independently, you can jump ahead to "Connecting to VNC" in order to stop the recording yourself
- Verify with MPV:
#+begin_example
mpv https://live0.emacsconf.org/gen.webm
mpv https://live0.emacsconf.org/dev.webm
#+end_example
- With luck, the 480p streams will be up automatically as well
#+begin_example
mpv https://live0.emacsconf.org/gen-480p.webm
mpv https://live0.emacsconf.org/dev-480p.webm
#+end_example
*** Connecting to VNC (option B)
1. Stop broadcasting locally if you were testing local OBS.
2. Install a VNC viewer on your system (ex: tigervnc-viewer).
3. 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
4. Copy the password:
scp emacsconf-$TRACK@res.emacsconf.org:~/.vnc/passwd vnc-passwd-$TRACK -p $SSH_PORT
5. Forward your local ports and connect via VNC viewer to the
appropriate forwarded port from your laptop:
#+begin_example
ssh emacsconf-$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-$TRACK &
#+end_example
(If this doesn't find a VNC server to connect to, you can start it with ~ssh emacsconf-$TRACK@res.emacsconf.org -p $SSH_PORT /home/emacsconf-$TRACK/bin/track-vnc~)
6. 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.
7. Verify with MPV on your local system:
#+begin_example
mpv https://live0.emacsconf.org/$TRACK.webm &
#+end_example
8. With luck, the 480p streams will be up automatically as well. On your local system:
#+begin_example
mpv https://live0.emacsconf.org/$TRACK-480p.webm &
#+end_example
9. Play a video. It should display the video and update the overlays. If you need to update the overlays manually, you can copy files from ~/data/emacsconf/overlays~ onto ~$HOME/other.png~ and ~$HOME/video.png~.
You can play a video with ~play video-id~ (ex: ~play meetups~), or you can specify the filename (ex: ~play ~/stream/emacsconf-2022-meetups*.webm).
termit: Ctrl-Shift-t makes a new tab
i3 cheat sheet:
- Alt-Enter creates a terminal
- Alt-d runs a command
- Alt-e toggles horizontal/vertical split
- Alt-f toggles full-screen
- Alt-w switches to tabbed view
- Alt-1 switches to workspace 1, Alt-2 switches to workspace 2
- Alt-Shift-2 moves things to workspace 2
- Alt-Shift-Left moves the current window to the left
- Alt-Shift-Right moves the current window to the right
10. Test Q&A. You can either wait for the video to finish or quit it with "q".
You can paste in the URLs or use
~firefox /data/emacsconf/2022/index-$TRACK.html~
11. Test adjusting the audio
- ~ssh emacsconf-$TRACK@res.emacsconf.org -p 46668~
- Then use ~qa-louder~, ~qa-quieter~, or ~qa-vol vol%~ (ex: ~qa-vol 90%~)
Other notes and tips:
- You can use Emacs for emergency or ad-hoc announcements.
- Use OBS or ~pavucontrol~ to adjust the volume of BBB as needed. You might be able to manage ~pavucontrol~ off-screen with ~ssh emacsconf-$TRACK@res.emacsconf.org -X -p $SSH_PORT pavucontrol~.
- You can also ~ssh emacsconf-$TRACK@res.emasconf.org -p 46668~ and start new processes from the command-line, such as using ~track-mpv~. If you specify commands when you call SSH instead of using an interactive shell, you may need to also specify DISPLAY=:5 (for the gen track) or DISPLAY=:6 (for the dev track), since ssh won't pick up the variables from ~.bashrc~.
- If you have a Wayland-only desktop without any X11 compatibility layer (example: [[https://swaywm.org][Sway]] with ~xwayland disable~) the suggested software (~tigervnc~) might no work. You can use instead for example ~gnome-remote-desktop~. The password for the VNC connection can be retrieved from the file ~vnc-passwd-$TRACK~ (3DES encrypted).
*** Managing the stream from the agenda (option B2)
ssh orga@res.emacsconf.org -p $SSH_PORT
emacsconf # runs emacsclient -c -a emacs
You can then use
- emacsconf-stream-play-video
- emacsconf-stream-open-qa-windows-on-change
- emacsconf-agenda-by-track
- emacsconf-agenda
If things are going well, you can use C-c C-t on the agenda view to change a talk to PLAYING, CLOSED_Q, or OPEN_Q, and various things should happen in the background. If they don't happen in the background, use emacsconf-add-org-after-todo-state-change-hook to add the todo state change hook, then try again.
Task state shortcuts for C-c C-t:
- m (mpv) :: PLAYING - -stream-play-video, emacsconf-stream-set-talk-info, publish the files to the media directory
- q (Q&A) :: CLOSED_Q
- o (open) :: update the BBB redirect URLs to let people into the room
- u (unstreamed)
- r (to archive)
You can leave the emacsclient with ~C-x 5 0~
**** Do Q&A
From the emacsclient on orga@res.emacsconf.org, you can open various talk-related things:
- emacsconf-stream-open-pad
- emacsconf-stream-join-qa
- emacsconf-stream-join-chat
Alternatively, you can switch to the VNC viewer and use the links in
file:///data/emacsconf/2022/index-gen.html or
file:///data/emacsconf/2022/index-dev.html .
For Q&A, you may want to have the Etherpad on the left, the BBB Q&A or
IRC chat on the right, and the terminal and OBS windows on
workspace 2.
*** Other tasks as needed
**** Display emergency news / announcements
M-x emacsconf-stream-broadcast to send a message to both streams
or M-x emacsconf-stream-set-news to send a message to one stream.
If that doesn't work, edit the news file directly with:
~ssh emacsconf-$TRACK@res.emacsconf.org > ~/news.txt~
If that doesn't work, use the VNC session to switch to an Emacs window
and type your message in.
**** Kill the VNC server:
ssh emacsconf-$TRACK@res.emacsconf.org "vncserver -kill"
| ~/bin/track-obs | start OBS with the track's profile and scene collection |
| ~/bin/track-mpv file.webm | play the file using the track's sink |
**** Making OBS scenes
Making OBS scenes is pretty straightforward as you can move the
different blocks on your scene in the preview window. However, it’s
important to make sure that your video-captures and your overlays are
snapping properly to the edges of the view-port. To do this, make sure
to right-click on the block inside the preview window, and try the
different fitting options (fit by width, height, etc.) until you find
one that works best.
We’ll probably be streaming at 720p, but since we’re also considering
a 1080p update, try to create your overlays in a format or a resolution
that would support resizing.
*** Other notes
There are sockets in the home directory for MPV control if you want to keep that process.

*** Other notes
- bandali doesn't have much cognitive bandwidth at the moment, so we can keep things simple with OBS on laptops
- Issue: zaeph was dropping frames and couldn’t pay attention to as many things as he wanted
- Issue: corwin needs assistance to not be locked in his chair for the whole conf. Premptively, zaeph can do it by broadcasting OBS scenes via the rtmp (instead of just his webcam).
- With a long day, we may want to be able to schedule hosts/streamers/publishers in shifts
- Ideal: Easy reproducible setup to spin up an OBS VM with scenes set up, allowing multiple users to connect to it at the same time. Maybe x2go or vnc? VMs with 8 vCPUs and a vGPU cost more, so it would be good to figure out what's needed, spin it down, and then spin it up maybe the day before or something like that.
- Plus points if we can control the OBS via password-protected websocket so we can tell it to switch scenes (and even more points if we do so from Emacs, maybe via that obs-websocket.el ;) ). MPV is also controllable via IPC, so we can use the same MPV player and then switch videos around. Maybe mpvc? https://unix.stackexchange.com/questions/664728/how-can-i-control-mpv-in-command-line
- Probably Linode's Dedicated 32 GB + RTX6000 GPU x1 at $1.50 an hour for 2-3 days + dev time, since live.emacsconf.org is in Linode as well
- We should also look into normalization across the board, especially if we have BBB participants. pipewire + easyeffects on the box might be the easiest way to do it.

:END:
Hi ${name}!
Thank you for volunteering to help with the captions for ${conf-name}
${year}! Last year, we were able to get almost all the talks captioned
in time for streaming. Participants found them very useful for
understanding different technical terms, names, accents, and so on.
We'd love to be able to pull that off again this year, and it would be
great to have you on board.
We've set up ${backstage} as the backstage area where you can view the
videos and resources uploaded so far. You can access it with the
username "${backstage-user}" and the password "${backstage-password}".
Please keep the backstage password and resources secret. If you see a
talk that you'd like to caption, you can e-mail me at
sacha@sachachua.com and I can reserve it for you. Then you can correct
any misrecognized words, fix capitalizations, remove filler words as
needed, and so on.
You'll probably want to work with either the VTT or the TXT versions
(VTT is WebVTT format and has timestamps), but you can check the other
talk resources in case the speaker has posted scripts or other useful
things. Both VTT and TXT are plain text, so feel free to use your
favourite text or subtitle editor. I've posted a brief demo of how I
edit captions at
https://media.emacsconf.org/2022/backstage/editing-captions.html , and
you can find more captioning tips at https://emacsconf.org/captioning/
. You can convert it to whatever format you like. If you prefer to
work with plain text, we can figure out the timestamps afterwards.
Let me know if you want to reserve a talk for captioning or if you have
any questions or suggestions. We're also in the #emacsconf-org channel
on the libera.chat IRC network, which you can connect to with your
favourite IRC client or through the web-based interface at
https://chat.emacsconf.org/ .

Goals:
- Ask speaker verify their scheduled time
It has already been confirmed with them, but it might have changed slightly
- HOW: They should check the time at the top of their talk page on the day of the conference
- Double-check Q&A preference, encourage tech checks for live talks/Q&A
- If they are available:
- Direct to tech-checks via https://emacsconf.org/${year}/prepare/
- Inform them of the check-in process
- They come say hi to us 30' before their session in #emacsconf-org or #emacsconf (they can use chat.emacsconf.org )
- We get them set up in a room where they can wait until the end of the broadcast of their pretention
- They’re joined by the streamer and host.
- Warning about potential emergency changes
Slightly more complex because of the conditionals

Hello, ${speakers-short}!
We're looking forward to having you join us at EmacsConf!
We've updated the schedule based on the submissions and cancellations,
and we'll probably update the schedule even on the day of the
conference. You can get a rough idea of your schedule on your talk
page${plural}. You might want to check your talk page${plural} some time next
week to get a rough sense of where it is, and then check it again on
the day of your talk${plural}. Please let me know if the times don't
work for you.
We'll try our best to keep your talk in the same general timeslot (ex:
Saturday morning, Saturday afternoon, Sunday morning, Sunday
afternoon). We've done some dry-runs, but just in case it turns out
that running two tracks at the same time leaves us too frazzled, we
may drop back to one track with Q&A on an alternate stream, like last
year. If there are big changes to your schedule on the day of your
talk${plural}, you'll get an e-mail from us with a subject like
"URGENT: EmacsConf 2022: ...".${wrap}
Here's your talk page URL and checkin information:
${checkin-info}
Please check in early so that we can deal with scheduling changes or
technical issues, and so that we don't worry too much about whether
you'll be ready to go for Q&A. =) You can find the check-in process at
${base-url}${year}/speakers/ .${waiting}
If something comes up, please let us know as soon as you can. Here's
my emergency contact information: ${emergency}
Thank you for sharing your time and energy with the EmacsConf community!
Sacha
p.s. If you need to cancel, that's okay too, life happens. Let me know
as soon as you can and I'll try to shuffle things around. Thank you!

Thank you so much for contributing a talk for EmacsConf ${year}! We're
looking forward to collecting questions and forwarding them to you by
e-mail after the conference. We'll also post the prerecording at the

If it turns out that you can make it to the conference after all, feel
free to drop us a line at #emacsconf-org and we'll let people know

Sorry about the last-minute change. We needed to update the schedule
because two tracks turned out to be too much for us to handle at the
moment. The new schedule will play all the talks on one stream, and
the other stream will handle Q&A.
Here's a copy of the updated schedule for your convenience:
${schedule}
Please check in at least 30 minutes before your talk (or 60 minutes if
you're going to do it live). https://emacsconf.org/2022/speakers/ has
more details.
You can also find the new schedule at the page URL${plural} above.
Please let me know if you can't make it. We can collect the questions
and you can follow up afterwards. You can reach me by e-mail or in
#emacsconf-org on IRC, or with this emergency contact info:
${emergency}
Thank you for your patience!

** DONE Ask emacsconf-org-private for feedback on early submissions
The EmacsConf 2022 CFP was extended to Sept 30 with notifications to
go out on Oct 15. We've got plenty of submissions and with any luck,
you've been reviewing them as they come in (assuming you have access to
emacsconf-submit@).
As a courtesy to people who got their stuff together in a timely manner
and to give them extra time to prepare a prerecorded talk (which might
also translate into extra time for us to process and caption the talks),
I'd like to send acceptances and tentative time allotments by Sept 30.
I plan to offer a max of 20 minutes with a note that additional time may
be available for Q&A depending on how many additional submissions we get.
Could everyone who wants a say in the program please add comments to
$url by **Sept 26** so that we can send out early acceptances? In
general, we try to say yes to everything, so here's your chance to
raise any red flags or suggest ways to make things even better.
Thanks!

Hi, ${speakers-short}!
Summary:
,${acceptance-tasks}
We've accepted your EmacsConf proposal${plural} for ${titles}! Thanks
for volunteering to share what you're learning about. I know it takes
a fair bit of work to prepare a presentation, so I appreciate that
you're taking the time to show what's possible with Emacs and
encourage people to learn more.
---------------------------------------------------------------------
${talk-details-and-comments}
---------------------------------------------------------------------
You'll have some time after your talk${plural} for Q&A, so the allocated time
can be just for your pre-recorded talk${plural}. Of course, if you like, you
can make it shorter.
We've posted preparation tips at https://emacsconf.org/${year}/prepare/ .
We'll send you instructions on how to upload files once we get that
set up.
Could you please plan to **put your pre-rec${plural} together by
${prerec-target}** (or even earlier if you want)? We're going to try
to caption as many talks as possible again this year, and extra time
helps a lot. People found the captions really helpful while watching
the stream, and sending your talk in early will make it more likely
that we'll be able to get your captions edited and reviewed before the
conference.
**Please reply to this e-mail by ${reply-date}** (doublechecking that
emacsconf-submit@gnu.org is in the To: or Cc:) so that we can confirm
that we've got the right email address for you and that messages can
get properly delivered. Also, would you like us to put ${email} as the
public contact information for you, or would you like us to add
something else to the talk page${plural}?
${page-urls}
If you have any questions, please e-mail us at
emacsconf-submit@gnu.org or pass by the #emacsconf-org IRC channel on
irc.libera.chat (Web-based: https://chat.emacsconf.org/#/connect).
Thank you so much!

Hi, ${name}!
I think we haven't heard from you since we accepted your EmacsConf
${year} proposal for "${title}". EmacsConf coming up soon, so I wanted
to check in with you to see how you're doing.
Could you please e-mail us to let us know if you're still working on
your prerecorded video, if you're planning to present live, or if you
can't make it this year? No worries if other priorities have come up
and you don't have the time for a presentation.
If you've been working on a presentation, fantastic! When you're
ready, you can upload it following the instructions at
https://emacsconf.org/${year}/prepare/ (ideally before ${prerec-date} so
that we have time to download it, doublecheck, etc.).
If you plan to present live, please go through the self-check at
https://test.bigbluebutton.org/ . Some speakers have encountered
technical issues with BigBlueButton that they didn't have with Zoom or
Google Meet, so this is something we definitely want to look into
earlier rather than later. If that works for you, please e-mail us
back so that I can keep your timeslot. The tentative schedule for your
talk is on the talk page at ${url} .
*Please e-mail us your plans before ${date}.* I'm
planning to shift the schedule around to give more time to confirmed
speakers for Q&A and possibly live demos. If I don't hear from you by
then (maybe an over-enthusiastic spam filter has been swallowing up
all our mail?), I'll probably reallocate the ${time} minutes that had
been set aside for your talk. We might be able to squeeze it back in
afterwards or play a video from you at the end of the conference day,
but it would be nice to get the schedule sorted out instead of
scrambling to fill gaps on the day of the conference.
Hope to hear from you by ${date}!

:SUBJECT: [need answer by Friday noon EST] EmacsConf ${year}: Don't have a prerec from you yet, aaah!
:EMAIL_ID: missing
:END:
Hi ${speakers},
EmacsConf is in a few days and I don't think we have your prerecorded
video yet, so I'm getting miiiildly stressed about the schedule. And
you're probably stressing out about it too, so let's go figure out how
we can make this work.
Option A: If you happen to have the prerecording or can get it done by
tomorrow, we can probably squeeze it in. Please upload it to
ftp-upload.emacsconf.org by following the instructions in
https://emacsconf.org/${year}/prepare#ftp-upload , or send us a link using
your favourite file-sharing service (especially if FTP is giving you
problems).
Option B: If you want to present live, it might be an option. I'm a little
worried about the potential for technical issues, since we've had
problems with that in previous EmacsConfs. The tight schedule means
there's not a lot of time to figure things out, and it can be hard to
make something as focused as a prerecorded video when you're doing it
live. We will definitely want to make sure that:
- your self-serve tech check works: https://test.bigbluebutton.org
at your convenience;
- you check in as early as possible (at least 1 hour before, so we
know if the speaker before you needs to extend) and let us know
that you want to do it live https://emacsconf.org/${year}/speakers .
We keep adapting the schedule as things come up, so please check
https://emacsconf.org/${year}/schedule/ on the day of the conference.
If there are technical issues or your talk runs a little over time, we
might have to stop streaming it on the main stream when it's time for
the next talk. We may be able to continue streaming it on the
alternate stream. If so, people can continue watching it there if they
wish to.
Option C: If you can't make it, that's okay. Life gets crazy
sometimes. Please let us know and we can update the wiki. If you
happen to be able to make a prerecorded video afterwards, we can add
that to the wiki, playlists, and announcements. We hope you can join
us next year.
Since EmacsConf is *this weekend* (aaaaaaah), please let us know by
tomorrow noon EST (Friday; 9AM PST, 5PM GMT, 6PM CET) so that we can
keep the time allocated for you in the schedule. If we don't hear from
you, we'll probably reallocate the ${time} minutes reserved for you so
that other talks can have longer Q&A. If you can still make it, check
in early and let us know so that we can try to work out an alternate
stream for you. Hope to hear from you soon!

#+begin_quote
Friends, emacsians, hackers, lend me your ears!
This is it, the final stretch until the next EmacsConf. A couple of weeks
ago, we’ve shared our program with you; now, it is time for us to share our
schedule, i.e. when the talks will happen!
You can find it on our wiki:
https://emacsconf.org/$year/schedule/
All the times on the program are listed in EST (UTC-5). If a talk catches
your eye, we invite you to click on its title to find out at what time it will
be broadcast in your local time. Also, if the talk is pre-recorded, it will
also be the time at which the talk will be made available on the same page.

Hi ${speakers-short}!
Thank you so much for being part of EmacsConf ${year}! Hundreds of people
enjoyed it, and I'm sure even more will come across the videos in the
days to follow.
Your prerecorded video is available on the talk page at ${url} , and
we've added the questions and comments that we've collected from
IRC/BBB/Etherpad. ${qa-note}
We've also uploaded your talk video to ToobNix (a PeerTube
instance) at ${toobnix-url} and YouTube at ${youtube-url} . If you
want to reupload the video to your own channel, feel free to do so.
${subtitle-note} If you let me know where you've uploaded
it, I can switch our playlist to include your version of the video
instead. That way, it might be easier for you to respond to comments
on videos.
If you would like to share more resources, you can add them to the
talk page or e-mail them to us and we can add them for you.
Thanks again for speaking at EmacsConf!

** From previous years
- [X] Shorter CFP, longer recording time
- [X] Ask for talk title to be subject in submission
- [X] Fresh eyes can doublecheck that all the talks are included and that availability properties have been set/followed
- [X] Putting ‘availability’ towards the top of the submission template would make it harder for us to miss it during reviews, and it shouldn’t change anything for speakers.
- [X] All the personalised messages we’ve sent during the scheduling campaign should probably be kept in a repo so that it’s less work for those who will be in charge of it next.
- [X] Since people kept running into ftp problems, we might want to set up a web-frontend next year to minimise problems.
- [X] Might be a good idea to avoid Thanksgiving weekend, as lots of people travel then
- [X] Tech-checks haven’t been really popular this year, but there are so many ways we could make them more useful. On the [2021-11-16 Tue], 10 days prior the conf, we thought that it could be nice to use them as recording sessions for late-prerecs, and that’s only one example.
- [X] Having the NO_NEWS / WAITING_FOR_PREREC contrast from the start of ~conf.org~ might have made it easier for us to ping speakers who were late to the party this year. Rather than sending the personalised 10 days prior to the conference, we might have sent it a week after the submission of the anticipated scheduled (where we ask speakers if their allocated time is okay, based on their availability).
- [X] Move first dry run earlier (maybe one month before?) to give us more time for process tweaks
- [ ] Dropping talks one week before the conf might allow us to have a near-fixed schedule to announce early.
- or we can plan for live or gaps, that's cool too
- [ ] CRM
- [ ] zaeph: Implementing a variable for ~automatic-emails~ would make it easier to suppress user-hooks for message-mode
- [ ]zaeph: Even though we’re sending emails automatically, we might want to keep trace of them in our ~Sent~ IMAP folder. notmuch does it with ~Fcc:~ in the header, so we might need a user-customisable var here as well.
- [ ] less tiring lighting
- [ ] split host and streamer?
- [ ] Cram less with different tracks
- [ ] Review pre-recs, even late submissions in their entirety to ensure no syncing issue
- [ ] Tight opening-remarks, possible pre-rec.
- [X] Asking pronunciation of name as soon as application with SA-cha CHEW-ah pattern would be good. Not a lot of diligence with it this year.
- [ ] People need to specify their IRC handle on application (potentially forcing nick and/or first-name/last-name.
- suggested, but not everyone has IRC, so that's okay. We'll manage. Walk new speakers through it?
- [ ] We might want to figure out an ffmpeg workflow for noise-suppressing on top of normalisation. Take inspiration from Audacity macros.
- [ ] Having a more relaxed Saturday might give us time to adjust to tech-stack.
- [X] Creating BBB rooms in anticipation and/or automatically, before or during, might make for smoother check-in; right now, people keep wanting to check in via email even though we told them to use chat
- One BBB room per talk
- [ ] Pre-recs were a little blocky wrt encoding; we might want to bump the bitrate next year
- [ ] we can see if bot + pads + merging will help next year, and we can also experiment with multiple streams if there are enough people to pull it off so that speakers don't feel like they've just been dropped in a room and left to their own devices :)
** Lessons learned for next year
*** CFP & Review period
- Ask for public e-mail or contact information, IRC handle in CFP
- Be even more stringent about the 10/20/40-min splits. A lot of
speakers still default to the 20- or 40-min formats without
providing us shorter formats, and that puts strain on our schedule
and requires us to use a different template for the notification
(which can be confusing). We need to stress that not respecting the
format makes it harder not only for the organizers, but also for the
speakers themselves (since they will have to rethink their
presentation). Maybe we can have an e-mail template for a quick
reply that says something like "Just in case we need to squeeze
talks into shorter times, could you please also propose an outline
for a possible 10-minute talk that could get people interested in
your topic and point them to where they can find out more?"
- Two people is the sweet number of reviewers to have for the
proposals before sending the notifications, and there’d be
diminishing returns with more. Two is enough to release the pressure
on SCHED, verify the metadata (esp. speaker availability), and
suggest a different ordering where appropriate. It can take a long
time to comb through the proposals (roughly 10 proposals per hour),
and whilst it’d be difficult to justify more in-depth reviewers,
other orgas can do a shallow-pass to catch red-flags or discuss the
submissions as they come in. Other organizers can always chime in on
topics they particularly care about so that their encouraging
comments or suggestions can be included in the acceptance e-mail.
- We extended CFP-end by two weeks this year, but that made it coincide
with speaker-notifs, and that’s awkward. Next time, we should only
extend the CFP by one week to avoid having to scramble with the
schedule until the very last day.
- Some people assume that they have to suggest longer formats even if
they intend their talks to be 10′ or 20′. We should change the
wording on the CFP to ask them to only provide alternatives for
shorter formats, not longer.
- It was hard to squeeze all the org/hyperbole talk on day-1.
Generally, the people who submit these kinds of talk come from all
over the world, and US mornings are more accommodating than US
evenings when it comes to timezones. We might consider having two org
*mornings* rather than an org *day*; it would give us more flexibility
with those talks.
- We’re starting to reach critical mass on the org-talks. We might want
to consider splitting the org-talks and the dev-talks into two
distinct events to allow them to grow independently.
- We should associate time-of-day with CFP-deadline; otherwise, the
scheduler has to be on edge until the very end of the day. It’s worse
this year because we made CFP-end coincide with speaker-notif, so this
might not be as much of a problem next year.
- It’s easier for us to extend beyond 5pm than to go before 9am
(especially for the West coast). Extending beyond 5pm puts strain on
European organizers and volunteers, though.
- Sometimes, ikiwiki on front0 took a lot of time to process the new
commits. sachac assumed this is due to a faulty regex parsing. We
should be able to find out more by looking at the logs from ikiwiki
after a slow commit.
- Ask for preferred timezone in CFP
- Check with John Wiegley re: schedule - we always happen to coincide with his work trips
*** When processing prerecs
- We should flesh out the prepare.md section on audio-recording because
some speakers have annoying coil-whines when recording from their
laptop’s microphone which are particularly hard to remove. We should
ask speaker to record some silence, listen to it in isolation, and
gauge how silent it actually is. It’s not a biggie though, since we
can usually degrade the audio quality for the sake of removing the
noise.
- We can ask for silence in a separate recording so that we don't have to worry about cutting it out.
** Possible big projects for next year
*** Prolog’ing the schedule
*** Designing the EmacsConf suite (to make it easier for people other us to run their own versions)
