Come share + your experiments and adventures with the Emacs text editor / operating + system / way of life! We welcome speakers of *all backgrounds* and + *all levels of experience*, including newcomers giving their first + talk. What have you found exciting about Emacs lately? What do you + wish someone had told you when you were starting out? What part of + your workflow might inspire someone to get into Emacs or go deeper? + + A great way to get started with writing a proposal is to start by + exploring the programs from previous years: [[https://emacsconf.org/2020/schedule/][2020]], [[https://emacsconf.org/2019/schedule/][2019]], [[https://emacsconf.org/2015/schedule/][2015]], [[https://emacsconf.org/2013/#program][2013]]. + You might also find some neat ideas on the [[https://emacsconf.org/2021/ideas/][ideas]] page.

You can join + the chat using [[ircs://irc.libera.chat:6697/emacsconf][your favourite IRC client]], or by visiting + [[https://chat.emacsconf.org][chat.emacsconf.org]] in your web browser. + + All kinds of people use Emacs for all kinds of things. We'd love it + if EmacsConf 2021 could highlight interesting perspectives and reflect + the diversity of our community. If you know someone who might have a + good idea for a talk, please reach out to them and encourage them to + submit a proposal. Many people (especially from underrepresented + groups such as women, people of colour, non-developers, etc.) might + not consider themselves expert enough to share their thoughts. If you + let them know that you value their knowledge and maybe even suggest + something that you think others would like to hear more about, they + may realize that they have something worth sharing and that we would + love to hear from them. + + * Important dates + + For EmacsConf 2021, we are planning for 9am to 5pm Toronto/EST + (2pm-10pm UTC) on November 27 and 28.

You can + always handle questions after the conference, and we might even be + able to coordinate with other Emacs meetups for regional events (if + you're an Emacs meetup organizer and would like to make this happen + let's [[https://emacsconf.org/contact/][get in touch]]!). + + Please note that although we will try our best to stick to the above + dates in the coming months, given the current state of the world, we + may have to move things around a bit in case of unforeseen events. + Thank you for your patience and understanding. + + * Talk formats + + We'd like EmacsConf 2021 to inspire lots of different people to + explore lots of different things in Emacs. We hope to put together a + stream of quick ideas followed by lots of conversation over IRC and/or + Q&A sessions, with occasional deep dives into topics that many people + might find interesting or useful. + + As you think about your talk, consider what you can share in: + + - *Up to 10 minutes total:* What is the core idea? What do you want + people to do or remember? You can show just enough to get people + interested and then point them to where they can learn more + afterwards. You can answer questions over IRC, the pad, or the + wiki, and there's no limit to how long that conversation can go. + + - *Up to 20 minutes total:* How would you flesh out some of the points + from your 5-10 minute presentation? How can you show the pieces + working together? + + - *Up to 40 minutes total:* What would benefit from a deep dive? + How do you keep it engaging? + + When writing your proposal, please write an outline of what you plan + to talk about if you have 5-10 minutes. If you'd like to propose a + longer talk, outline what you might include if you had more time to + present (up to 40 minutes, including Q&A). + + Here's an example for a potentially 40-minute talk: + + - 5-10 minutes: quick demo of the abc package working together with + xyz package. + - 20 minutes: same as above, with some customization options to + accommodate a different workflow. + - 40 minutes: all of the above, including modifying the behaviour of + the package in order to add something new. + + This flexibility would help us in devising the conference schedule so + that as many people as possible could get a chance to present their + ideas, while still allowing for featuring longer deep dive talks. + + Other session formats such as tutorials, workshops, and hangouts are + welcome as well, in case you would find those other formats preferable + to a traditional talk format. If you're interested in these or other + session types, please let us know [[https://lists.gnu.org/mailman/listinfo/emacsconf-org][publicly]] or [[https://lists.gnu.org/mailman/listinfo/emacsconf-org-private][privately]]. We'll be + happy to work something out with you. + + * Office hours + + We're aware that it can be intimidating to submit a proposal to a + conference, so we thought we'd try to help! This year, we're opening + up the doors of our virtual offices for you to come talk to us about + your proposals with hopes of helping you with any hurdles you may be + facing with preparing your proposal. + + We'd like to publish a schedule of availabilities of volunteers for + holding office hours. Currently these volunteers consist of some of + the EmacsConf organizers, but we'd love to have the help of other + members of the Emacs community as well. If you are a more experienced + Emacs user and would like to help with this, please [[https://emacsconf.org/contact/][get in touch]]! + + Our first office hour this year is planned for Saturday, August 14, + from 3pm to 4pm UTC with zaeph (Leo Vivier) at the following + BigBlueButton room: https://bbb.emacsverse.org/b/ban-qye-fd1-5kw. + + * Submitting your proposal + + Once you're ready to submit your proposal, the [[https://emacsconf.org/2021/submit/][submit]] page has the + instructions on how to submit your talk. + + We use an anonymized submission process to reduce bias and encourage + contribution. Identifying information will be removed from + submissions by a conference organizer who will not participate in + talk selection. The anonymized submissions will then be reviewed by + a selection committee. + + If your talk is approved, we'd love it if you could help us make sure + the conference runs smoothly. After we email you with the time + allotted for your talk, we'll ask you to + + - prepare a prerecording of your talk, or record it with our help if + that'd be easier for you; and + - schedule a short tech-check if you'd like to be able to answer + questions in a live session. + + Don't forget to subscribe to our main mailing list, [[https://lists.gnu.org/mailman/listinfo/emacsconf-discuss][emacsconf-discuss]], + for discussion and announcements about the EmacsConf conference. + + We look forward to your ideas and submissions! + + * Getting involved + + If you would like to help with the conference (planning the sessions, + reviewing proposals, helping with infrastructure, making sessions more + accessible, editing video transcripts, etc.), see our [[https://emacsconf.org/2021/planning/][planning]] page + and come say hi to us at =#emacsconf= on =irc.libera.chat=. + + In addition to the [[https://lists.gnu.org/mailman/listinfo/emacsconf-discuss][emacsconf-discuss]] list, feel free to subscribe to + [[https://lists.gnu.org/mailman/listinfo/emacsconf-org][emacsconf-org]] as well, for discussions related to organizing the + conference by the EmacsConf organizers and volunteers. + + We'd really appreciate your help in making EmacsConf 2021 the best one + so far! + + * Commitment to freedom + + We remain fully committed to freedom, and we will continue + using our infrastructure and streaming setup consisting entirely + of [[https://www.gnu.org/philosophy/free-sw.html][free software]], much like previous EmacsConf conferences. + An article describing our infrastructure and tools is underway, + and will be announced on the emacsconf-discuss list when published. + + + * COMMENT Copyright & License + + Copyright (c) 2020 Amin Bandali, Sacha Chua, David Bremner + Copyright (c) 2021 Amin Bandali, Sacha Chua, Leo Vivier, + Sebastian Crane + + The EmacsConf 2021 Call for Proposals is part of the EmacsConf wiki, + and is dual-licensed under the terms of the Creative Commons + Attribution-ShareAlike 4.0 International Public License; and the GNU + General Public License as published by the Free Software Foundation, + either version 3 of the License, or (at your option) any later + version. + + A copy of these two licenses is available on the EmacsConf wiki, in + the [[https://emacsconf.org/COPYING.CC-BY-SA][COPYING.CC-BY-SA]] and [[https://emacsconf.org/COPYING.GPL][COPYING.GPL]] files. + + * COMMENT How to export this file + + As of the time of writing this document (Org mode version 9.3.7), the + Org links library (=ol.el=) does not yet recognize =ircs= link types, + and will throw an error if you try to export a file containing them, + such as this file. + + To work around that, you can use something along the lines of the + Emacs Lisp code below, by either adding it to your init file, or by + putting the point in the code block and hitting =C-c C-v e= (that is, + hold Ctrl, then hit c followed by v, then release Ctrl, and hit e) to + evaluate the code, working around the issue only for the current + session. + + #+begin_src emacs-lisp :results silent + (org-link-set-parameters + "ircs" + :export + (lambda (link description format) + "Export an ircs link. + See `org-link-parameters' for details about LINK, DESCRIPTION and + FORMAT." + (let ((desc (or description link))) + (pcase format + (`html (format "<a href=\"ircs:%s\">%s</a>" link desc)) + (`md (format "[%s](ircs:%s)" desc link)) + (_ nil))))) + #+end_src + + +<a id="second-cfp"></a> + +### Second (and final) call for proposals (closing Sep 30) :email: + +Sent Sept 27, 2021 to the same lists as the CFP +Included inline Markdown and attached Org version of the CFP + +- E-mail text + + Dear fellow Emacsians, + + This is the second and final Call for Proposals for EmacsConf 2021, + open until September 30.

A few weeks ago, +we excitedly shared the EmacsConf 201 program with you. We're now +happy to share the conference schedule with you, i.e. the program +plus each talk's (approximate) scheduled time slot: + +<https://emacsconf.org/2021/schedule> + +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 the '~' tildes near the times, indicating that they are +approximations and not meant to be taken as exact times. + +On November 27 and 28 you will be able to watch the livestreams via +<https://live.emacsconf.org>, which also has details on how to watch the +streams using media players that support streaming (like mpv and VLC). +Also, for Asia-Pacific folks, there will be an alternate stream by +LibreAustralia, at 11:00-17:30 UTC+11 on Sunday, November 28. Please +see the <https://libreau.org/upcoming.html#emacsconf21> page on their +site for more details and how to tune into the alternate stream. + +Last but not least, please see the <https://emacsconf.org/2021> page +of the EmacsConf wiki for more details on watching and participating +in the conference. + +We hope to see you all around on November 27-28 for EmacsConf 2021! + +Amin Bandali, Leo Vivier, and Sacha Chua, +On behalf of the EmacsConf 2021 organizers team + + +<a id="follow-up-prerecs"></a> + +## Follow up regarding prerecorded videos :email: + +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/2021/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; +- we have your emergency contact information in case of frozen + Internet connection, etc. Please e-mail us the phone number we can + use to call you. We promise to use it only for EmacsConf 2021 + emergency coordination; and +- 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/2021/speakers> . + We keep adapting the schedule as things come up, so please check + <https://emacsconf.org/2021/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.

Come share +your experiments and adventures with the Emacs text editor / operating +system / way of life! We welcome speakers of *all backgrounds* and +*all levels of experience*, including newcomers giving their first +talk. What have you found exciting about Emacs lately? What do you +wish someone had told you when you were starting out? What part of +your workflow might inspire someone to get into Emacs or go deeper? + +A great way to get started with writing a proposal is to start by +exploring the programs from previous years: [[https://emacsconf.org/2020/schedule/][2020]], [[https://emacsconf.org/2019/schedule/][2019]], [[https://emacsconf.org/2015/schedule/][2015]], [[https://emacsconf.org/2013/#program][2013]]. +You might also find some neat ideas on the [[https://emacsconf.org/2021/ideas/][ideas]] page. Feel free to +add yours there too! If you're still not sure, come by our IRC +channel =#emacsconf= on =irc.libera.chat= and say hi. You can join +the chat using [[ircs://irc.libera.chat:6697/emacsconf][your favourite IRC client]], or by visiting +[[https://chat.emacsconf.org][chat.emacsconf.org]] in your web browser. + +All kinds of people use Emacs for all kinds of things. We'd love it +if EmacsConf 2021 could highlight interesting perspectives and reflect +the diversity of our community. If you know someone who might have a +good idea for a talk, please reach out to them and encourage them to +submit a proposal. Many people (especially from underrepresented +groups such as women, people of colour, non-developers, etc.) might +not consider themselves expert enough to share their thoughts. If you +let them know that you value their knowledge and maybe even suggest +something that you think others would like to hear more about, they +may realize that they have something worth sharing and that we would +love to hear from them. + +,* Important dates + +For EmacsConf 2021, we are planning for 9am to 5pm Toronto/EST +(2pm-10pm UTC) on November 27 and 28. Depending on people's +availability, it might be two half-days. + +| CFP opens | August 5, 2021 | +| CFP closes | September 30, 2021 | +| Speaker notifications | October 15, 2021 | +| Schedule published | October 31, 2021 | +| EmacsConf 2021! | November 27 and 28, 2021 | + +If you are not available during the conference itself but you have a +neat idea that you'd like to share, please propose it anyway! You can +always handle questions after the conference, and we might even be +able to coordinate with other Emacs meetups for regional events (if +you're an Emacs meetup organizer and would like to make this happen +let's [[https://emacsconf.org/contact/][get in touch]]!). + +Please note that although we will try our best to stick to the above +dates in the coming months, given the current state of the world, we +may have to move things around a bit in case of unforeseen events. +Thank you for your patience and understanding. + +,* Talk formats + +We'd like EmacsConf 2021 to inspire lots of different people to +explore lots of different things in Emacs. We hope to put together a +stream of quick ideas followed by lots of conversation over IRC and/or +Q&A sessions, with occasional deep dives into topics that many people +might find interesting or useful. + +As you think about your talk, consider what you can share in: + +- *Up to 10 minutes total:* What is the core idea? What do you want + people to do or remember? You can show just enough to get people + interested and then point them to where they can learn more + afterwards. You can answer questions over IRC, the pad, or the + wiki, and there's no limit to how long that conversation can go. + +- *Up to 20 minutes total:* How would you flesh out some of the points + from your 5-10 minute presentation? How can you show the pieces + working together? + +- *Up to 40 minutes total:* What would benefit from a deep dive? + How do you keep it engaging? + +When writing your proposal, please write an outline of what you plan +to talk about if you have 5-10 minutes. If you'd like to propose a +longer talk, outline what you might include if you had more time to +present (up to 40 minutes, including Q&A). + +Here's an example for a potentially 40-minute talk: + +- 5-10 minutes: quick demo of the abc package working together with + xyz package. +- 20 minutes: same as above, with some customization options to + accommodate a different workflow. +- 40 minutes: all of the above, including modifying the behaviour of + the package in order to add something new. + +This flexibility would help us in devising the conference schedule so +that as many people as possible could get a chance to present their +ideas, while still allowing for featuring longer deep dive talks. + +Other session formats such as tutorials, workshops, and hangouts are +welcome as well, in case you would find those other formats preferable +to a traditional talk format. If you're interested in these or other +session types, please let us know [[https://lists.gnu.org/mailman/listinfo/emacsconf-org][publicly]] or [[https://lists.gnu.org/mailman/listinfo/emacsconf-org-private][privately]]. We'll be +happy to work something out with you. + +,* Office hours + +We're aware that it can be intimidating to submit a proposal to a +conference, so we thought we'd try to help! This year, we're opening +up the doors of our virtual offices for you to come talk to us about +your proposals with hopes of helping you with any hurdles you may be +facing with preparing your proposal. + +We'd like to publish a schedule of availabilities of volunteers for +holding office hours. Currently these volunteers consist of some of +the EmacsConf organizers, but we'd love to have the help of other +members of the Emacs community as well. If you are a more experienced +Emacs user and would like to help with this, please [[https://emacsconf.org/contact/][get in touch]]! + +Our first office hour this year is planned for Saturday, August 14, +from 3pm to 4pm UTC with zaeph (Leo Vivier) at the following +BigBlueButton room: https://bbb.emacsverse.org/b/ban-qye-fd1-5kw. + +,* Submitting your proposal + +Once you're ready to submit your proposal, the [[https://emacsconf.org/2021/submit/][submit]] page has the +instructions on how to submit your talk. + +We use an anonymized submission process to reduce bias and encourage +contribution. Identifying information will be removed from +submissions by a conference organizer who will not participate in +talk selection. The anonymized submissions will then be reviewed by +a selection committee. + +If your talk is approved, we'd love it if you could help us make sure +the conference runs smoothly. After we email you with the time +allotted for your talk, we'll ask you to + +- prepare a prerecording of your talk, or record it with our help if + that'd be easier for you; and +- schedule a short tech-check if you'd like to be able to answer + questions in a live session. + +Don't forget to subscribe to our main mailing list, [[https://lists.gnu.org/mailman/listinfo/emacsconf-discuss][emacsconf-discuss]], +for discussion and announcements about the EmacsConf conference. + +We look forward to your ideas and submissions! + +,* Getting involved + +If you would like to help with the conference (planning the sessions, +reviewing proposals, helping with infrastructure, making sessions more +accessible, editing video transcripts, etc.), see our [[https://emacsconf.org/2021/planning/][planning]] page +and come say hi to us at =#emacsconf= on =irc.libera.chat=. + +In addition to the [[https://lists.gnu.org/mailman/listinfo/emacsconf-discuss][emacsconf-discuss]] list, feel free to subscribe to +[[https://lists.gnu.org/mailman/listinfo/emacsconf-org][emacsconf-org]] as well, for discussions related to organizing the +conference by the EmacsConf organizers and volunteers. + +We'd really appreciate your help in making EmacsConf 2021 the best one +so far! + +,* Commitment to freedom + +We remain fully committed to freedom, and we will continue +using our infrastructure and streaming setup consisting entirely +of [[https://www.gnu.org/philosophy/free-sw.html][free software]], much like previous EmacsConf conferences. +An article describing our infrastructure and tools is underway, +and will be announced on the emacsconf-discuss list when published. + + +,* COMMENT Copyright & License + +Copyright (c) 2020 Amin Bandali, Sacha Chua, David Bremner +Copyright (c) 2021 Amin Bandali, Sacha Chua, Leo Vivier, +Sebastian Crane + +The EmacsConf 2021 Call for Proposals is part of the EmacsConf wiki, +and is dual-licensed under the terms of the Creative Commons +Attribution-ShareAlike 4.0 International Public License; and the GNU +General Public License as published by the Free Software Foundation, +either version 3 of the License, or (at your option) any later +version. + +A copy of these two licenses is available on the EmacsConf wiki, in +the [[https://emacsconf.org/COPYING.CC-BY-SA][COPYING.CC-BY-SA]] and [[https://emacsconf.org/COPYING.GPL][COPYING.GPL]] files. + +,* COMMENT How to export this file + +As of the time of writing this document (Org mode version 9.3.7), the +Org links library (=ol.el=) does not yet recognize =ircs= link types, +and will throw an error if you try to export a file containing them, +such as this file. + +To work around that, you can use something along the lines of the +Emacs Lisp code below, by either adding it to your init file, or by +putting the point in the code block and hitting =C-c C-v e= (that is, +hold Ctrl, then hit c followed by v, then release Ctrl, and hit e) to +evaluate the code, working around the issue only for the current +session. + +,#+begin_src emacs-lisp :results silent +(org-link-set-parameters + "ircs" + :export + (lambda (link description format) + "Export an ircs link. +See `org-link-parameters' for details about LINK, DESCRIPTION and +FORMAT." + (let ((desc (or description link))) + (pcase format + (`html (format "<a href=\"ircs:%s\">%s</a>" link desc)) + (`md (format "[%s](ircs:%s)" desc link)) + (_ nil))))) +,#+end_src + +#+end_src +*** Second (and final) call for proposals (closing Sep 30) :email: +:PROPERTIES: +:CUSTOM_ID: second-cfp +:END: +Sent Sept 27, 2021 to the same lists as the CFP +Included inline Markdown and attached Org version of the CFP + +**** E-mail text +:PROPERTIES: +:SUBJECT: [ANN] EmacsConf 2021 Second (and final) Call for Proposals (closing Sep 30) +:END: + +Dear fellow Emacsians, + +This is the second and final Call for Proposals for EmacsConf 2021, +open until September 30.

We will definitely want to make sure that: + - your self-serve tech check works: https://test.bigbluebutton.org + at your convenience; + - we have your emergency contact information in case of frozen + Internet connection, etc. Please e-mail us the phone number we can + use to call you. We promise to use it only for EmacsConf 2021 + emergency coordination; and + - 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/2021/speakers . + We keep adapting the schedule as things come up, so please check + https://emacsconf.org/2021/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 ${duration} 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! + +Sacha +** Offer speakers the opportunity to go live if they really really want to :email: +:PROPERTIES: +:CUSTOM_ID: go-live-maybe +:END: +Sent November 25 +*** Email text +Thank you so much for sending in your prerecording. We were able to +caption most of the talks, yay! That will help more people appreciate +the talks, and it'll make it easier for people to look up technical +terms too. The talks will be streamed with open captions, and the talk +pages will have the videos with closed captions when they're streamed. + +We're still adapting the schedule as stuff comes up, so please check +the schedule again on the day of the conference and check in as early +as you can.
