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). # About this document Tags: - `conforg`: Requires access to private conf.org repository # Communications plan Objectives: - keep everyone in the loop without them feeling like they’re overloaded Everyone: - [ ] Call for participation (speakers and volunteers) - [ ] Reminder about CFP - [ ] Last call Speakers: - [ ] Send all speakers backstage access and upload instructions - [ ] Send all speakers check-in instructions Volunteers: - [ ] Send captioning volunteers the backstage info - [ ] Send past captioning volunteers an invitation to participate - ask when there’s a lot of load - [ ] Ask for help with audio processing # Good/better/best This table makes it easier to move the slider depending on who wants to volunteer and how much we can get done. At some point, we’ll figure out how to track our current status so we know what we need to scramble to do in order to get the conference off the ground. **bold** is our current goal. Feel free to volunteer for anything that interests you!

# Phases ## DONE Draft CFP #### Draft linked pages - [X] cfp - [X] submit page - [X] year index - [X] volunteer page #### DONE Check with other organizers #### DONE Post CFP in the usual places emacsconf-discuss, reddit.com/r/emacs, Emacs News, emacs-tangents, Mastodon, X ## TODO Draft schedule 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 [graph](https://emacsconf.org/2024/talks/graph "Graph mode: a major mode to create, edit and display discrete element graphs"), moved [p-search](https://emacsconf.org/2024/talks/p-search "p-search: a local search engine in Emacs") earlier; also [learning](https://emacsconf.org/2024/talks/learning "Survival of the skillest: Thriving in the learning jungle") needs to be in the morning, so I moved [pgmacs](https://emacsconf.org/2024/talks/pgmacs "PGmacs: browsing and editing PostgreSQL databases from Emacs") and [org-teach](https://emacsconf.org/2024/talks/org-teach "org-teach: a minor mode for writing course materials in Emacs") around. - [2024-10-22 Tue] Swapped [org-teach](https://emacsconf.org/2024/talks/org-teach "org-teach: a minor mode for writing course materials in Emacs") and [blee](https://emacsconf.org/2024/talks/blee "About Blee: enveloping our own autonomy directed digital ecosystem with Emacs") - [2024-10-21 Mon] Extended [blee](https://emacsconf.org/2024/talks/blee "About Blee: enveloping our own autonomy directed digital ecosystem with Emacs") - [2024-10-17 Thu] Added [org-update](https://emacsconf.org/2024/talks/org-update "The Future of Org") to Saturday morning, moving [org-teach](https://emacsconf.org/2024/talks/org-teach "org-teach: a minor mode for writing course materials in Emacs") to Sunday afternoon - [2024-10-15 Tue] Swapped [students](https://emacsconf.org/2024/talks/students "An example of a cohesive student workflow in Emacs") and [literate](https://emacsconf.org/2024/talks/literate "Literate programming for the 21st Century") for availability reasons - [2024-10-13 Sun] Moved [hyperdrive](https://emacsconf.org/2024/talks/hyperdrive "New in hyperdrive.el: quick install, peer graph, transclusion!") to the afternoon (swapping with [flp](https://emacsconf.org/2024/talks/flp "The Free Life Planner: Empowering lives with Emacs-based AI")) because of changed availability - [2024-10-12 Sat] I fixed the time constraint for [students](https://emacsconf.org/2024/talks/students "An example of a cohesive student workflow in Emacs") (needs to be in the afternoon), so I moved [hyperbole](https://emacsconf.org/2024/talks/hyperbole "Fun things with GNU Hyperbole") to the morning. - General approach: - I’ve mostly tried to alternate IRC/pad Q&A with live Q&A. - 1.5 tracks keeps things faster-paced than the 2-track option. - Sat: - Gen track: - [papers](https://emacsconf.org/2024/talks/papers "Writing academic papers in Org-Roam"), [project](https://emacsconf.org/2024/talks/project "Managing writing project metadata with org-mode"), [org-teach](https://emacsconf.org/2024/talks/org-teach "org-teach: a minor mode for writing course materials in Emacs"), [flp](https://emacsconf.org/2024/talks/flp "The Free Life Planner: Empowering lives with Emacs-based AI"), [color](https://emacsconf.org/2024/talks/color "Colour your Emacs with ease") should be pretty general - [color](https://emacsconf.org/2024/talks/color "Colour your Emacs with ease") and [theme](https://emacsconf.org/2024/talks/theme "My journey of finding and creating the “perfect” Emacs theme") are both theme-related. [color](https://emacsconf.org/2024/talks/color "Colour your Emacs with ease") needs to be in the morning and [theme](https://emacsconf.org/2024/talks/theme "My journey of finding and creating the “perfect” Emacs theme") needs to be in the afternoon, so I put them on either side of the lunch break. - Other afternoon talks: [water](https://emacsconf.org/2024/talks/water "Watering my (digital) plant with Emacs timers") and [shell](https://emacsconf.org/2024/talks/shell "Emacs as a shell") are by the same speaker. [casual](https://emacsconf.org/2024/talks/casual "Re-imagining the Emacs user experience with Casual Suite"), [hyperdrive](https://emacsconf.org/2024/talks/hyperdrive "New in hyperdrive.el: quick install, peer graph, transclusion!"), and [writing](https://emacsconf.org/2024/talks/writing "Emacs Writing Studio") will probably be good for a general audience. These speakers are only available in the afternoon, so this part of the schedule is a bit tight. - I put [emacs30](https://emacsconf.org/2024/talks/emacs30 "Emacs 30 Highlights") 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: - [gypsum](https://emacsconf.org/2024/talks/gypsum "Gypsum: my clone of Emacs and ELisp written in Scheme"), [rust](https://emacsconf.org/2024/talks/rust "An experimental Emacs core in Rust"), [julia](https://emacsconf.org/2024/talks/julia "Exploring shared philosophies in Julia and Emacs"), [guile](https://emacsconf.org/2024/talks/guile "Beguiling Emacs: Guile-Emacs relaunched!"), and [mcclim](https://emacsconf.org/2024/talks/mcclim "Elisp and McCLIM") are about other projects - [graph](https://emacsconf.org/2024/talks/graph "Graph mode: a major mode to create, edit and display discrete element graphs"), [p-search](https://emacsconf.org/2024/talks/p-search "p-search: a local search engine in Emacs"), [secrets](https://emacsconf.org/2024/talks/secrets "Committing secrets with git using sops-mode"), and [repro](https://emacsconf.org/2024/talks/repro "Reproducibly building Emacs: “Hey your checksum is the same as mine!”") 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: [students](https://emacsconf.org/2024/talks/students "An example of a cohesive student workflow in Emacs"), [links](https://emacsconf.org/2024/talks/links "Unlocking linked data: replacing specialized apps with an Org-based semantic wiki"), [regex](https://emacsconf.org/2024/talks/regex "Emacs regex compilation and future directions for expressive pattern matching") - [blee](https://emacsconf.org/2024/talks/blee "About Blee: enveloping our own autonomy directed digital ecosystem with Emacs") and [language](https://emacsconf.org/2024/talks/language "Immersive language learning with Emacs") are probably general-audience - [pgmacs](https://emacsconf.org/2024/talks/pgmacs "PGmacs: browsing and editing PostgreSQL databases from Emacs"), [regex](https://emacsconf.org/2024/talks/regex "Emacs regex compilation and future directions for expressive pattern matching"), and [transducers](https://emacsconf.org/2024/talks/transducers "Transducers: finally, ergonomic data processing for Emacs!") are all development-oriented, but are on the general track for scheduling purposes. [transducers](https://emacsconf.org/2024/talks/transducers "Transducers: finally, ergonomic data processing for Emacs!") can only be on Sunday afternoon at 4pm because of availability. - I’ve separated [hyperbole](https://emacsconf.org/2024/talks/hyperbole "Fun things with GNU Hyperbole") and [hywiki](https://emacsconf.org/2024/talks/hywiki "HyWiki: Fast, hyperlinked note-taking with no markup required") by lunch so that people who are interested in that can attend the live Q&A for both without worrying about missing things. - [learning](https://emacsconf.org/2024/talks/learning "Survival of the skillest: Thriving in the learning jungle"), [sharing](https://emacsconf.org/2024/talks/sharing "So you want to be an Emacs-fluencer?"), [literate](https://emacsconf.org/2024/talks/literate "Literate programming for the 21st Century") will probably be good for a general audience ## DONE Prepare shift calendar, ask people to sign up AM: 9-12 PM EST, PM: 1-5 PM EST (plus a little extra for setup/transition) Saturday Dec 7 2024

You can ask questions in the web conference by joining from the talk page, or you can ask questions through Etherpad or IRC. ### WAITING Rerecord intro for Ihor Radchenko and Bastien Guerry zaeph’s tips: Ihor said his name in this presentation: You’re rolling your Rs for both “Ihor” and “Guerry”, but I think both are supposed to be smooth. For Bastien’s family name, it’s “ghey-ree”. zaeph will probably pronounce this so much better than I can. =) Next, we have "The future of Org", by Ihor Radchenko and Bastien Guerry. They will answer questions via web conference. You can join using the URL from the talk page or ask questions through Etherpad or IRC. ### TODO Rerecord Eev intro with MAC-SYM-A pronunciation :record:emacsconf: > My name in the intro is perfect, but Maxima comes from Macsyma, and it is > pronounced mac - sym (<- as in “symbolic”) a… Next, we have "Emacs, eev, and Maxima - now!", by Eduardo Ochs. You can ask questions via Etherpad or IRC. ### WAITING Rerecord Vincent Conus using psitransfer version :record:emacsconf: cuhn-us Next, we have "Writing academic papers in Org-Roam", by Vincent Conus. He will answer questions via web conference. You can join using the URL from the talk page or ask questions through Etherpad or IRC. ### WAITING Rerecord Joseph Turner with new title :emacsconf:record: [2024-12-02 Emacs news](https://sachachua.com/blog/2024/12/2024-12-02-emacs-news/) New in hyperdrive.el: quick install, peer graph, transclusion! Next, we have "New in hyperdrive.el: quick install, peer graph, transclusion!" by Joseph Turner. You can ask questions in the web conference by joining from the talk page, or you can ask questions through Etherpad or IRC. ### STARTED Record sat-open remarks :emacsconf:record: Welcome to EmacsConf 2024, where we have fun exploring how much we can do with a text editor. It’s hard to give a general overview of all the cool talks today and tomorrow, so you can flip through the talks and see what sparks your interests. Don’t feel limited to one track or another. The best parts of EmacsConf are the conversations. The wiki has a page on how to watch and participate, and I’ll give you a quick overview as well. You can watch both streams at live.emacsconf.org using free and open source software. Using a streaming media player like mpv seems to be the best way to watch in terms of performance but there are also web-based players just in case that’s all you’ve got. The schedule shows the General track on top and the Development track on the bottom, so you can see what else is going on. As you’re watching the talks, you can refer to the schedule in another window. Hover over the boxes to see the times and titles, and click on the boxes in the schedule to jump to the talk’s page for more details. You can also get the schedule as an iCalendar file or as an Org file in different time zones. Many talks will be followed by live Q&A web conferences with the speaker, which will be done in BigBlueButton or BBB. These are indicated with a solid border on the schedule and by Q&A: BBB on the schedule page. You can join the web conference room by clicking on the BBB link on the schedule page or the talk’s webpage. Then you can ask your questions yourself when the Q&A starts. To improve performance, please keep your webcam off and stay muted until it’s your turn to talk. If you don’t like Javascript, you can still ask questions via IRC and the hosts can read them out for you. We’re probably going to automatically switch between talks and Q&A sessions, so the transitions on the stream might be a little sudden. People in the BigBlueButton room can continue the conversation even after the talk moves off-stream. and you can also reach out to the speakers using the contact information on the talk page. Other talks will have Q&A via Etherpad or IRC, depending on what the speakers prefer. This is indicated in the schedule with a dashed border and on the schedule page as well. Some talks will have the Q&A after the event, so you can add your questions to their Etherpad or ask on IRC. We’ll e-mail the speakers afterwards and update the talk pages when they answer. The schedule pages and track pages have quick shortcuts so that you can find out more about talks, open the Etherpads, and join the Q&A sessions. The watch page has more tips on how to make the most of Q&A. If you can, please add notes and ask questions in the Etherpad for the talk. That makes it easier for everyone to share their notes, and speakers and hosts can read the questions from there. We’ll copy the notes to the talk pages afterwards. We have one pad for each talk, so you can follow the links to get to the next one or go back to the schedule and get the link from there. If you have general feedback about the conference itself, please put it in pad.emacsconf.org/2024 , which is linked on each pad. You can also use this as a general community message board for things like Help Wanted. Internet Relay Chat or IRC can be another great way to be part of lots of conversations. You can use chat.emacsconf.org to join the IRC channels through your web browser. The tabs on the left can help you switch between the different channels. There’s #emacsconf-gen for the General track and #emacsconf-dev for the Development track. If you need to reach us, you can join #emacsconf-org or e-mail emacsconf-org-private@gnu.org. You can use #emacsconf for hallway conversations. Of course, you can join any of these channels with your favourite IRC client. You can connect to irc.libera.chat port 6697 with TLS. Once again, we’re going to be streaming with open captions for most of the talks this year, thanks to our speakers and captioning volunteers. The captioned talks are indicated on the schedule, and with any luck, we’ll be posting transcripts on talk pages shortly after the talks start. If you need additional accommodations, please let us know in #emacsconf-org and we’ll see if we can make things happen. If something goes down, we’ll update status.emacsconf.org. If it doesn’t look like we’ve noticed yet, please let us know in the #emacsconf-org IRC channel, where we will be quietly panicking. In all of these conversations, please keep in mind our guidelines for conduct. You can find them on the wiki, They basically boil down to: please be nice. If all goes well, the prerecorded talks and transcripts should be available from the talk pages shortly after they start playing, and we’ll post the recordings of live talks and Q&A sessions within the next month or so. If you’d like to get an update, you can subscribe to the emacsconf-discuss mailing list. All right, let’s get going. Leo is hosting the general track, and Corwin hosting the development track. The other volunteers and I will run around mostly backstage, and you’ll probably meet us in the closing remarks. That’s also where we get to thank all the people and organizations who make EmacsConf possible. Thanks for coming to EmacsConf 2024. ### TODO Record sun-open remarks Welcome to the second day of EmacsConf 2024. Today we have one track of talks, so you don’t have to worry about missing out on anything. The best parts of EmacsConf are the conversations.

We’ll e-mail the speakers afterwards and update the talk pages when they answer. We’re going to start Sunday morning with more IRC/Etherpad Q&A to try to get around some of the bandwidth issues that we noticed last year. The schedule pages and track pages have quick shortcuts so that you can find out more about talks, open the Etherpads, and join the Q&A sessions. The watch page has more tips on how to make the most of Q&A. If you can, please add notes and ask questions in the Etherpad for the talk.

This file overrides the timing of when systemd runs bbb-record-core.target.

# Decisions ## BigBlueButton replacement (BBB) The server running bbb.emacsverse.org has been decommissioned, since the nonprofit that shared it with us is defunct. - We’d like to figure out what our live Q&A setup is going to be for EmacsConf 2024 (Dec 7-8). - Nice to have: Hosting for other Emacs meetups like Emacs APAC and OrgMeetup - [Stats from last year](https://sachachua.com/blog/2023/12/emacsconf-backstage-figuring-out-our-maximum-number-of-simultaneous-bigbluebutton-users/): 31 meetings, 84 unique users, 62 max simultaneous users, 6 max simultaneous meetings, 27 max users in one meeting, 36 unique talking - also includes some notes on hosting - Nice thing about running our own server: we can make one room per speaker, pre-assign their URLs, and let people stay as long as they want in recorded Q&A sessions Recommendation: We spin up a shared CPU 4GB under bandali’s Linode account (for bandwidth pooling and easier reimbursement), do the setup/testing, scale down as small as possible over the next few weeks, scale up to dedicated CPU 16GB a day or two before the conference, and keep it at that level until the recordings are all done. I have access to that Linode account, so I can set it up. If bandali can configure emacsverse.org to be handled by Linode, I can manage the DNS changes, or he can change bbb.emacsverse.org to the IP address of the new node. Some options: - Linode with 16GB RAM and 8 cores - Advantages: can experiment with both Galene and BBB, manage things ourselves, have filesystem access - Disadvantages: needs someone to do it - Base pricing - Shared CPU 4GB 80GB storage: hourly USD 0.04, monthly USD 24 - Dedicated CPU 16GB: hourly USD 0.22, daily 5.28, weekly 36.96, monthly USD 144 - meets minimum requirements and can probably support 200 simultaneous ([FAQ](https://docs.bigbluebutton.org/support/faq/)) - Shared CPU 8GB 160GB storage: hourly USD 0.07 - Shared CPU 16GB 320GB storage: hourly USD 0.14 - Last year - Block storage: $1/10GB/month - 125M/hour - [FAQ](https://docs.bigbluebutton.org/support/faq/#what-is-the-disk-space-usage-for-storing-one-hour-of-recordings) - 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? - - Economy 120 (USD 130/month) or Economy 80 (USD 85/month), custom URL - - 100 concurrent users: USD 125/month, custom URL - - 100 concurrent users: USD 79/month - 200 concurrent users and custom URL: USD 15 setup fee + USD 149/month - - 150 concurrent, USD 75/month - - 250 concurrent, USD 49 setup + USD 108.80/month - - 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.
