-If we take all talks at the minimum time requested (and maybe nudge
-the retro gaming talk to be a lightning talk because it's been covered
-elsewhere, and maybe nudge the eev talk to be a lightning talk as
-well), we can probably fit in the 80% schedule.  If we're feeling
-confident about time, we can prioritize some talks and make them a bit
-longer.  Prerecorded lightning talks would give us more flexibility,
-as usual.
-
-I removed reviewer identification. Note that if you commit to the Git
-repository, your commit is tagged with whatever you're using for
-identification.  If you want to stay anonymous-ish (... and you
-haven't already posted it to the public emacsconf-org list =) ), you
-can send comments to Amin or me and we can put them in for you.
-
-If you move a talk around or change the time
-allocated to it, use =M-x my/org-sum-min-time-in-subtree= (see [[Code]])
-to recalculate each affected subtree.  (Someday we should have
-something that will update everything!)
-
-I've added some of my thoughts to the talks that a reviewer wasn't
-sure about (see the quote blocks) to see if we can get those talks to
-be a good fit.
-
-Does anyone have strong feelings about saying no to some talks in
-order to give more time to other talks? There are some pretty
-promising ones that could benefit from more time.  We'll probably have
-more time freed up if people withdraw talk proposals or if we move
-lightning talks around (last year we queued up a whole bunch at the
-end), so we might not have to say no right away unless we feel
-strongly about it.

-#+begin_quote
-It might be good to nudge this to be a lightning talk since eev was in
-last year's conference as well.  What's new in terms of the talk
-coverage?
-#+end_quote
-
-Name: Eduardo Ochs
-
-****** Preferred format
-
-Extended talk
-
-****** Abstract
-
-In the last months there were several hundreds of messages in
-emacs-devel in threads with names like "A proposal for a friendlier
-Emacs", "How to make Emacs popular again", and "Interactive guide for
-new users".  On the one hand I am absolutely sure that eev is very
-good answer to all these themes; on the other hand I know that eev is
-based on some design decisions that offend most people used to modern,
-"user-friendly" interfaces - and I feel that at this moment mentions
-to eev in those discussions in emacs-devel would not be welcome.
-
-In this talk I will start by presenting very quickly the main "killer
-features" of eev - namely:
-
-  1) Elisp hyperlinks,
-
-  2) interactive tutorials that can be navigated with just three keys,
-
-  3) non-invasiveness - people can easily turn eev on for only five
-     minutes each week, play with it a bit, and then turn it off,
-
-  4) high discoverability factor,
-
-  5) a way to create "hyperlinks to here",
-
-  6) hyperlinks to specific points in PDF documents and video files -
-     i.e., to specific pages, strings, and timemarks,
-
-  7) a way to control shell-like programs ("eepitch"), and
-
-  8) an Elisp tutorial,
-
-and after that I will present the design decisions behind eev, in two
-parts:
-
-  1) eev is a very thin layer above Emacs-the-Lisp-environment; it is
-     as simple as possible, but in the sense of "simple" that was used
-     in Forth, and that is not very familiar today.
-
-  2) Very often when I am using Emacs - which is my main interface
-     with the system - I realize that I can automate some task that I
-     just did by hand twice of thrice; and that I should do that,
-     because automating that would be both easy and fun.  Over the
-     years I experimented with several ways of automating tasks,
-     refined some of these ways a lot, and found a certain "best"
-     style that, again, usually offends people who are accustomed with
-     the modern ideas of user-friendliness.  In this style, used in
-     most template-based functions in eev, both textual documentation
-     and error-handling are kept to a minimum.  I will show how, and
-     why, eev makes this style works so well, and how users can create
-     their own templated functions very quickly - as "5-minute hacks".
-
-****** (Un)availability
-
-I will be available the whole day.
-
-****** Speaker release
-
-By submitting this proposal, I agree that my presentation at EmacsConf
-2020 is subject to the following terms and conditions:
-
-The EmacsConf organizers may capture audio and video (a "Recording")
-of my presentation and any associated materials, which may include
-slides, notes, transcripts, and prerecording(s) of my presentation
-that I provide to the EmacsConf organizers.
-
-I authorize the EmacsConf organizers to distribute, reproduce,
-publicly display, and prepare derivative works of the Recording and
-any derivative works of the Recording (the "Licensed Materials") under
-the terms of the Creative Commons Attribution-ShareAlike 4.0
-International (CC BY-SA 4.0) license.
-
-I grant to the EmacsConf organizers permission to use my name,
-likeness, and biographic information in association with their use of
-the Licensed Materials under the above license.
-
-I represent that I have the authority to grant the above license to
-the EmacsConf organizers.  If my presentation incorporates any
-material owned by third parties, I represent that the material is
-sublicensable to the EmacsConf organizers or that my use of them is
-fair use.

+Name: Eduardo Ochs
+
+***** Preferred format
+
+Extended talk
+
+***** Abstract
+
+In the last months there were several hundreds of messages in
+emacs-devel in threads with names like "A proposal for a friendlier
+Emacs", "How to make Emacs popular again", and "Interactive guide for
+new users".  On the one hand I am absolutely sure that eev is very
+good answer to all these themes; on the other hand I know that eev is
+based on some design decisions that offend most people used to modern,
+"user-friendly" interfaces - and I feel that at this moment mentions
+to eev in those discussions in emacs-devel would not be welcome.
+
+In this talk I will start by presenting very quickly the main "killer
+features" of eev - namely:
+
+  1) Elisp hyperlinks,
+
+  2) interactive tutorials that can be navigated with just three keys,
+
+  3) non-invasiveness - people can easily turn eev on for only five
+     minutes each week, play with it a bit, and then turn it off,
+
+  4) high discoverability factor,
+
+  5) a way to create "hyperlinks to here",
+
+  6) hyperlinks to specific points in PDF documents and video files -
+     i.e., to specific pages, strings, and timemarks,
+
+  7) a way to control shell-like programs ("eepitch"), and
+
+  8) an Elisp tutorial,
+
+and after that I will present the design decisions behind eev, in two
+parts:
+
+  1) eev is a very thin layer above Emacs-the-Lisp-environment; it is
+     as simple as possible, but in the sense of "simple" that was used
+     in Forth, and that is not very familiar today.
+
+  2) Very often when I am using Emacs - which is my main interface
+     with the system - I realize that I can automate some task that I
+     just did by hand twice of thrice; and that I should do that,
+     because automating that would be both easy and fun.  Over the
+     years I experimented with several ways of automating tasks,
+     refined some of these ways a lot, and found a certain "best"
+     style that, again, usually offends people who are accustomed with
+     the modern ideas of user-friendliness.  In this style, used in
+     most template-based functions in eev, both textual documentation
+     and error-handling are kept to a minimum.  I will show how, and
+     why, eev makes this style works so well, and how users can create
+     their own templated functions very quickly - as "5-minute hacks".
+
+***** (Un)availability
+
+I will be available the whole day.
+
+***** Speaker release
+
+By submitting this proposal, I agree that my presentation at EmacsConf
+2020 is subject to the following terms and conditions:
+
+The EmacsConf organizers may capture audio and video (a "Recording")
+of my presentation and any associated materials, which may include
+slides, notes, transcripts, and prerecording(s) of my presentation
+that I provide to the EmacsConf organizers.
+
+I authorize the EmacsConf organizers to distribute, reproduce,
+publicly display, and prepare derivative works of the Recording and
+any derivative works of the Recording (the "Licensed Materials") under

+I grant to the EmacsConf organizers permission to use my name,
+likeness, and biographic information in association with their use of
+the Licensed Materials under the above license.
+
+I represent that I have the authority to grant the above license to
