In light of the new development philosophy for Org-mode, I would like
to present my developer story from discovering Org-mode in 2014 to
becoming a maintainer for a big project in 2020.  The goal is to show
the logical progression between interest, gaining skills, becoming an
expert, authoring, contributing and maintaining, in hope that it would
bolster people to do the same.

As someone who majored in a non CS-related degree, I feel that my
story has a potential to grasp the attention of many attendees, since
I basically started from the bottom of the ladder.  Most people should
be able to relate to one step on that ladder, which should hopefully
encourage them to reach for the next step.

I am in CET, and I would rather have the presentation early in the day
(9am-12pm EST would be stellar).  If need be, I could present later,
but I do not think I would be as effective.

****** Talk information

You want to write a novel, but you don't know how to create an
outline.  You have a seed idea for a novel, and you intend to expand
it into a complete story.  You have many ideas for a novel, and you
are wondering how to proceed.  You started writing your heart out, and
you now feel the need to create a framework for a novel.

Worry not, Emacs is here to the rescue.

Listen to this talk to find out how to develop your story idea into a
framework for a novel, all within your favourite text editor, Emacs.

What you will learn during the session:

- How to write a single-line plot for a novel
- How to write the backbone of the novel, the main character arc
- How to create characters and write their arcs
- How to create a story design
- How to create the scenes design
- How to plan your novel writing project
- How to track your project

The modified Emacs template has all the ingredients and flow to start
from a basic idea to a full fledged thrashed out novel superstructure.

Once you are done with the superstructure, you can use the planning
and clocking infrastructure to finish scene after scene, thus
finishing your masterpiece.

We will use:

- The snowflake method -
https://www.advancedfictionwriting.com/articles/snowflake-method/
- The seven-point story structure -

LilyPond is an extensible program for producing high-quality sheet
music engraved with traditional layout rules.  Similar to LaTeX and
other typesetting programs, its input format simply describes the
visual layout of the score using commands to define musical
expressions.  This makes collaboration easier, prevents users from
having to adjust layout settings manually, and faciliates digital
archiving and distribution of musical scores.  In this talk, I begin
by showcasing LilyPond syntax and mode using literate programming
techniques as examples for building sheet music in Emacs, and proceed
with an overview of the setup I use for producing music books with GNU
Make, LilyPond, and LilyPond-mode.

I hoped to become a successful musician someday, and while that has
yet to happen, I've recorded a fair share of unreleased music over the
years.  I decided it was time to share some of it with the world
through the power of Emacs!

Rather than using the available non-free (or even free?) platforms out
there, I decided to build a Bandcamp-like page from scratch.  While I
could have chosen many of the static-site building tools, I decided to
use the tool closest to my heart and automate the process of building
a web page from a directory of audio files with Emacs Lisp.

I will share with you how I managed to create a personal workflow for
releasing an album without leaving the One True Editor that includes
editing audio metadata with EMMS and generating HTML while cobbling
together yasnippet and the format macro.

I think this might be a better fit as a lightning talk or maybe a
standard talk that demonstrates the concept with a few well-chosen
examples. A possible goal might be to show people that they can
develop a mental model and remap more keys to fit it.
#+end_quote

****** Talk information

A practiced dexterity with the arcane incantations known as keybindings is
the true mark of the veteran Emacs user. Yet, it takes years to get there,
and if you tried to explain what you were doing there, nobody would
understand, least of all those Vim users who would say that the whole
enterprise was foolhardy to begin with. They don't get it, those fools. Let
them flounder about in their "normal mode." Normal isn't good enough for
me! I want exceptional, IDEAL, I want... glorious mode, that's what I want.
And the only thing that'll cut it is if I do it ... my way. Why, with my
precious emacs.d, I'm invincible! Well... just between you and me, there
are times when learning new keybindings every time someone makes a new toy
gets to be a bit of a drag, and some days I can't keep my C-c's and my C-c
C-c's straight if I'm being honest with you, but you'll never catch me
admitting it! I do wonder if there's a better way to get to glorious mode,
even though my .emacs.d is already perfect (of course).

If this secretly sounds like you, then rejoice, there just might be a new
way, a better way! And you could potentially get there in days instead of
years, so that even your script kiddie coworker with their "VSCode" (groan)
may at last come around to your way of looking at things, and, maybe, just
maybe, even those Vim users (hiss!)!

"Epistemic" Emacs is a user interface paradigm based on treating aspects of
the user interface as conceptual entities that can be reasoned about in
terms of a standard language. Essentially, instead of learning keybindings
for each specific action, you learn keybindings for general, conceptual
habits, kind of like Vim, except that instead of reasoning only about text,
you reason about any aspect of your interaction with the machine, whether
it's windows or buffers or even those interactions themselves. The promise
of this approach is that you just learn a simple language once, and you can
then apply it to vastly different aspects of your user interface, with the
same keybindings doing different things in different contexts, in sensible
and predictable ways. And in principle, whenever that new toy technology
comes around, anyone could extend the UI language to apply to it in a
matter of minutes, and you'd already know how to use it.

****** Talk information

It's not always easy to take part of someone's configuration and make
it work, it's almost never easy to move your configuration to fresh OS
installation or hardware.  Not sure that this snippet is enough to
make package work?  Forgot to install ripgrep in your system for
rg.el?  Got a broken version of package on package-install?

There is a way to make an Emacs configuration reliable, composable and
self-contained.  It's possible to freeze package versions, create
systemd unit for emacs daemon, maintain system dependencies and
package subconfigurations in one place with one tool.

The talk explains how to leverage the power of nix package manager and
use-package to make pretty good emacs configuration.

There is a stream record on the same topic:
https://youtu.be/2_e3kPJQ93s.  It lacks few interesting points about
composability of such configuration approach, but already have enough
interesting information.  The talk will be a little more structured
and more Emacs-users oriented.

****** Talk information

 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".

I'm also not sure we need a 20-minute tutorial on Org Mode, since it's
a perennial topic for other videos.  I suppose people unfamiliar with
Org Mode will probably benefit from a quick pointer to beginner
resources (maybe a 5-minute pointer).  I'm always curious about Org
workflows, though, so if this talk is rejigged as a workflow demo, it
might be a good fit for 10-20 minutes.
#+end_quote

***** Talk information

This is a talk about Orgmode, my favorite Emacs application.  The goal
is to show you the power of Emacs when you want to manage and organize
your life.  Orgmode is your swiss army knife for that job, and so far
the only tool that you can customize for your needs and you need to
customize yourself to fit the restrictions of a "ToDo list tool".

Background info: I'm using Orgmode for many years now, and I'm not
exaggerating if I tell you that it saved me from a nervous breakdown
when my wife got diagonosed with severe illness and I was suddenly in
charge of everything.  Orgmode was there and reminded me of the
important things so nothing was forgotten and I could focus on what
really matters.

This talk should introduce people to Orgmode, showing them what they
can do and how it makes your life easier, freeing time for the things
that matter to you.

I was holding a similar talk at the local Linux Day in our town in
2017.  In 2016 I recorded a set of tutorial videos which are available
on my YouTube channel which gained more than 3500 subcribers because
of those tutorials.  In Summer 2020 I recorded the tutorials again for
a course at Udemy which went online in October 2020 and is
supplemented by a 100+ pages course book.

The world is full of possibilities. A person life is rather short
though, and one can easily end up carry on without focus.

In this short talk I want to share how Org mode empowers me into
organizing and monitoring my tasks to make sure I am working towards
achieving my vision.

The emphasis of the talk is on defining a direction, monitoring the
progress towards your planned destination, and keeping a trail of your
actions to review and set up a healthy feedback loop.

***** Talk information

Many discussions have been had over the years on the debate between
using few big files versus many small files.  However, more often than
not, those discussions devolve in a collection of anecdotes with
barely any science to them.

Once and for all (or, at least until org-element.el get overhauled), I
would like to settle the debate by explaining why the way we parse
Org-mode files becomes slower as our files grow in size or numbers,
and how that affects their browsing and the building of custom-agenda
views.

I feel qualified to talk about this topic for two reasons:
- I went through the trouble of optimising my agenda-views by
  implementing clever regex-based skips, so I know the ceiling that
  can be reached with the current tech.
- My work on Org-roam has led me to consider the use of an external
  parser for Org-mode files, and whilst we are only at the prototyping
  stage, we know what is at stake.

I intend the talk to be fairly light-hearted and humorous, which is the
only way we can do true justice to the topic.

***** [#B] Talk information

We present a short experience report from the perspective of two
long-time Emacs users and one relative newcomer.  Our motivations
relate, broadly, to reproducibility of research in science.  We
reflect on our experiences with off-the-self solutions available
through the Emacs package manager, and describe some of our custom
extensions.

When working on a scientific research project, one typically has
multiple different computer programs running at the same time.  For
example, we may use a computer algebra system such as Maxima for
calculations, an interactive language such as Julia for numerical
computations, TeX for writing up results, a reference manger such as
Zotero for the bibliography, Roam for note-taking, and Jekyll for
blogging.  Switching and moving content among these programs can be
distracting, time-consuming, and prone to error.  These issues are
compounded when there are several collaborators involved.

We explore a solution that looks toward building better "computational
notebooks" using Emacs.  We take Org mode as our foundation.  As many
in this audience will know, Org mode integrates features such as
writing, task management, program evaluation, typesetting,
presentation, and navigation.  Tightly integrated add-on packages
round out the picture either by directly replacing the functionality
of the other programs mentioned above or automatically dispatching
commands to them.  We outline both the pleasure and pain involved in
this experience.

Many source code projects these days begin with a README file. While most
people use markdown, if you use org-mode you can use literate programming
to generate all of your source code directly from the documentation.

This strategy is a great way to keep your documentation from getting
outdated, and it allows you to use all the other wonderful features of
org-mode. Watch "README-Driven Design" to see exactly how to make your

Org-roam is a Roam replica built on top of the all-powerful Org-mode.

Org-roam is a solution for effortless non-hierarchical note-taking with
Org-mode.  With Org-roam, notes flow naturally, making note-taking fun
and easy.  Org-roam should also work as a plug-and-play solution for
anyone already using Org-mode for their personal wiki.

Org-roam aims to implement the core features of Roam, leveraging the
mature ecosystem around Org-mode where possible.  Eventually, we hope to
further introduce features enabled by the Emacs ecosystem.

# ----------------------------------------------------------------------

# I am one of the co-maintainers for Org-roam.

The purpose of the talk is to introduce people to Org-roam, whether
they be Org-mode connoisseurs or newcomers.  A lot of people have
found value in adopting Org-roam and the Zettelkasten method in their
workflows, and the goal is to demonstrate how they achieved it.  The
last part will present the future milestones that are in store for
Org-roam.

#+begin_quote
org-roam has a lot of talks in this agenda, but it (and other
Zettelkasten-type things) have resulted in a lot of buzz in the Org
community, so it's probably worth looking at it from the intro, user,
and dev perspectives. It would be good to get the presenter
coordinating with the one doing the org-roam overview in order to
minimize overlap. This might even be doable in a lightning talk.
#+end_quote


***** Talk information

Org-mode improved so much over the years, and the use-cases in org-mode are
vast and highly technical. There is something for everyone in org-mode, and
it's important to sift through all of these features and figure out what's
best for a given situation or specific users. Therefore, I will be
targeting academics and scholars that are engaging with literature in the
early stages of a project or their academic careers.

Academics and scholars engage with complex ideas and unstructured research
workflows. I believe that org-mode can add more structure to the madness,
and I will use this talk to clarify a possible solution to reduce such
complexity.  I propose a research workflow framework that utilizes
org-mode, its raw form, and its many associated packages. However, the main
package I will be mostly talking about is Org-Roam, and the way its
underlying principles will revolutionize the research workflow.

This presentation will help researchers organize and build their knowledge
database in a streamlined and effective way. The research workflow is
presented in three phases: planning, note-taking, and reference management.
I will talk briefly about the packages and special-use cases for each stage
and learned lessons along the way. Finally, the presentation concludes with
future considerations and possible org-mode features.

# ----------------------------------------------------------------------

The purpose of the talk is to present some technical aspects of
Org-roam.  From the very beginning, we wanted Org-roam to scale with
your notes, and this meant that we had to keep a close eye on our
performances.  As we iterated, optimisation remained a top-priority,
leading us to constantly peek under Org-mode's hood.  Not only has
this made us better developers, but it has also uncovered paths of
optimisation for Org-mode itself.

The talk is targeted at software engineers willing to peek under
Org-mode's hood.  A rudimentary understanding of Elisp will be
required.

Points to be covered
- SQL database via emacsql
- Elisp libraries
- Parsing of Org-mode files
- org-elements.e
- Parsing with a background-process
- Ensuring consistency via hooks

In this 20m talk I'll briefly introduce some rationales leading to
storing all game source and play state information within org-mode

***** Talk information

Users will generally only make use of a few predefined `special
blocks', such as `example, centre, quote', and will not bother with
the effort required to make new ones.  When new encapsulating notions
are required, users will either fallback on HTML or LaTeX specific
solutions, usually littered with `#+ATTR' clauses to pass around
configurations or parameters.

Efforts have been exerted to mitigate the trouble of producing new
special blocks.  However, the issue of passing parameters is still
handled in a clumsy fashion; e.g., by having parameters be expressed
in a special block's content using specific keywords.

We present a novel approach to making special blocks in a familiar
fashion and their use also in a familiar fashion. We achieve the
former by presenting ``defblock'', an anaphoric macro exceedingly
similar to ``defun'', and for the latter we mimic the usual
``src''-block syntax for argument passing to support special blocks.

For instance, here is a sample declaration.

#+begin_example
(defblock stutter () (reps 2)
  "Output the CONTENTS of the block REPS many times"
  (org-parse (s-repeat reps contents)))
#+end_example

Here is an invocation that passes an /optional/ argument; which
defaults to 2 when not given.

#+begin_stutter :reps 5
Emacs for the win ⌣̈
#+end_stutter

Upon export, to HTML or LaTeX for instance, the contents of this block
are repeated (`stuttered') 5 times.  The use of ``src''-like
invocation may lead to a decrease in `#+ATTR' clauses.

In the presentation, we aim to show a few `practical' special blocks
that users may want: A block that ...
  - translates /some selected/ text ---useful for multilingual blogs
  - hides /some selected/ text ---useful for learning, quizzes
  - folds/boxes text ---useful in blogs for folding away details
In particular, all of these examples will be around ~5 lines long!

We also have a larger collection of more useful block types, already
implemented.

The notable features of the system are as follows.
  + Familiar ``defun'' syntax for making block ---``defblock''
  + Familiar ``src'' syntax for passing arguments ---e.g., ``:key
    value''
  + Fine-grained control over export translation phases ---c.f.,
    ``org-parse'' above
  + *Modular*: New blocks can be made out of existing blocks really
    quickly using ``blockcall'' ---similar to Lisp's ``funcall''.  We
    will show how to fuse two blocks to make a new one, also within ~5
    lines.

It is hoped that the ease of creating custom special blocks will be a
gateway for many Emacs users to start using Lisp.

***** Talk information

Tree-sitter is a parser generator and an incremental parsing library.
emacs-tree-sitter is its most popular Emacs binding, which aims to be
the foundation of Emacs packages that understand source code's
structure.  Examples include better code highlighting, folding,
indexing, structural navigation.

In this talk, I will describe the current state of emacs-tree-sitter's
APIs and functionalities.  I will also discuss areas that need
improvements and contribution from the community.

***** (Un)availability

The conference will start at 9PM in my timezone (GMT+7).  I would

***** Talk information

Emacs, show me how much technical debt and where it is in this
software repository!

Also how complex is this module?

And who is the main developer of this component?

Mmm, if I change this file, do I need to change something else, Emacs?

Ah, I need help of somebody to change this code! Emacs can you tell me
who knows something about this file?

The above are some questions my Emacs can answer (an M-x away).

It all started with "Your Code as a Crime Scene", an insightful book
by Adam Tornhill, and it continued with a big useful hack.

In this talk I want to show the analyses I can produce on software
repositories with my Emacs, explain how they help me in my daily work,
give a bit of context of how Adam came up with them, and show the
dirty code that makes this wonderful functionality work.

***** Preferred format

Lightning talk (pre-recorded video is possible)

***** Talk information

If you are working with complex nested JSON structures, you are
probably familiar with jq which is like sed for JSON data and great at
what it does.  However, being a command-line tool like sed, the
feedback for writing queries and seeing their results is a discrete
process and not live.

When working with Emacs, we are used to good auto-completion and live
feedback.  Formerly, this was mostly done with static input, but with
modern completion frameworks like Ivy and Counsel, this can be done
with dynamic inputs, as well.

counsel-jq is a package with which you can quickly test queries and
traverse a complex JSON structure whilst having live feedback.  Just
call =M-x counsel-jq= in a buffer containing JSON, then start writing
your =jq= query string and see the output appear live in the message
area.  Whenever you're happy, hit =RET= and the results will be
displayed to you in the buffer =*jq-json*=.

In this lightning talk, I'll give a quick overview on how to use
counsel-jq and how to build similar completion functionality.

***** (Un)availability

Probably good idea to reach out to this speaker and check on the angle
of this talk.  It could be a good way to explore the question of how
new people discover Emacs, get motivated to try Emacs, and get through
the roadblocks, keeping in mind that it's from personal experience.
#+end_quote

***** Talk information

Could Emacs be humanity's solution to the turbulent years of
adolescence?  So much more than a text editor, Emacs changed the way I
approach everything at the age of 15.  In the two years since
discovering Emacs in my sophomore year of high school, I have been
constantly amazed at what Emacs is capable of.  In this talk, I would
like to share this journey of discovery and what I've learned along
the way, beginning with what led me to Emacs.  I will describe the
many ways that Emacs has shaped my life as a student, a programmer, a
violinist, and a productive and happy adolescent.  In each case, I
have thoroughly enjoyed figuring out the best way to make Emacs work
for me, and I'd like to share this with others.  In addition, I'd like
to take this opportunity to address some roadblocks that I have
noticed having observed some of my peers' attempts at learning Emacs
and possible solutions for those barriers, taking inspiration from
various sources both from inside and outside the Emacs community.

***** Talk information

Dungeon is an oral and physical media fantasy and abstract role-play
gaming tradition that seems to have grown from miniature and
war-gaming communities in and around the University of Minnesota, Twin
Cities in the 1950s and 60s.

Dungeon is inherently free (or nearly free, you do need paper and
dice), both to play and to create your own games.  Moreover, as a
generality among practices, as Dungeon authors, we dislike impositions
on our creative freedoms beyond those of our own imagination and
tastes, especially those such as of a "brand" or "system", or e.g.
copyright holder.

In December of 2019 some friends who grew up creating and playing in
each others' Dungeons decided to try making an engine for these types
of games using Emacs and Emacs Lisp, org-mode, and maybe some
duct-tape if needed.  In this 50 minute talk Corwin and Erik introduce
dungeon-mode, and explain why we decided to do that.  We'll sketch out
the project in both lay and technical terms, provide a tactical update
with respect to completing our initial concept, describe how things
are going in human terms, and share some things we've learned so far
from and about Emacs and the free software community working on this
project, while leaving 10-15m for questions and discussion.

***** Preferred format

Standard talk (20m, including 5m Q&A)

***** Talk information

We hope the dungeon-mode project will eventually support three primary
use-cases related to editing/designing, playing and running/hosting
RPG games.  In a "vanilla" game, characters descend from the "General
Store" (the one safe haven available) into the dungeon, a (nominally)
underground labyrinth of unknown dimensions with generally asocial
occupants and occasional bits of treasure.

Players can track (as long as the "lights" stay on) the location of
their party of characters via a process we usually call "mapping".
This has usually involved the dungeon master "calling out" the shape
of the map level as the party, in turn, calls out their route or
"pathing" decisions.

#+begin_example
   DUNGEON-MASTER
      "Corridor East-West"
   PARTY-LEADER
       "West"
   DUNGEON-MASTER
      "Ten feet, corridor ends goes South"
   PARTY-LEADER
      "South"
   DUNGEON-MASTER
      "Step into an area.  It's a
       twenty-by-twenty area extending
      West, with exits in the Western
      part of the southern wall and the
      Southern part of the eastern wall."
             **rolls dice**
      "Nothing waiting in the area"
#+end_example

Mapping quickly emerged as a focal point for development.  Especially,
we were to excited to try creating an 'on-the-fly' graphical
representation of the map that could respond to changing in-game
circumstances.  (Oops, all your Elves are dead.  Where'd the secret
doors go?)

During this 20m talk I'll provide a couple of reference points on
Emacs's image and especially SVG rendering capabilities, then
introduce a series of proofs-of-concept focusing on our experience
using core libraries such as `svg.el' to make them.

As of submitting abstracts, these include
 * "DM map view" - select and render a complete game map,
 * "play mode map" - progressively render maps based on game action,
 * "battle-board" - track damage taken by player characters, and
 * "character-sheet" - a graphical character sheet
 * "previews" - view map tiles when hovering their draw code in org
 * "sketch" - a "click-to-draw" experiment

For an advanced peek please see our git repository (but note we're
moving to Savannah soon).  We'll be talking first about [[https://github.com/dungeon-mode/game/blob/master/src/dm-map.el][map.el]],
especially `dm-map-draw' and helpers.  A few sample game maps this can
render are available as org-mode documents in the [[https://github.com/dungeon-mode/game/blob/master/Docs/Maps][Docs/Maps]] folder.

Those interested could compare functions between dm-map.el and
[[https://github.com/dungeon-mode/game/blob/master/src/dm-draw.el][dm-draw.el]], which is an incomplete rewrite of the "SVG rendering"
functions used only by [[https://github.com/dungeon-mode/game/blob/master/src/dm-sketch.el][dm-sketch.el]] (so far).  Hopefully, it will be
writing our "sketches" back out to org docs in time for the
conference.

The project is transitioning to Savannah.  Please watch for
redirects/moved notices when using these links.

***** Preferred format

10 minutes - Lightning talk
I am flexible.  I've done a 5 minute version as well.

***** Talk information

When I began learning Lakota, the language of my ancestors, there was
no way for me to type it on a computer without using non-free
software.  Additionally, the only software I could find supported just
one of the proposed orthographies for the language.

As an Emacs user, I knew that free software offered the ability for
many types of languages to co-exist in the same program and went
looking for how to enable an input mode for Lakota in Emacs.  This
talk will discuss how Emacs enabled me to define input modes for
multiple Lakota orthographies using the Quail multilingual input
package.

I will also discuss some of the ethical and cultural considerations I
went through when publishing the package.  Lakota and many other
indigenous languages were actively suppressed for many years, and are
in danger of extinction.  The language is being recovered now, but
much of the available educational material comes from non-indian
people.  Before publishing an input mode for Emacs, I wanted to ensure
that I included an orthography developed by Lakota people, not only
the suggested orthography present in most of my educational material.
Additionally, the choice of where to publish the source as an Emacs
package was important, since some corporations have been known to
support ongoing oppression against indigenous descended peoples.

20 minutes should be fine (I'm happy to record in advance, as well).
It would be fun to have a Q&A, if that's an option.

***** Talk information

The venerable Gnus newsreader has evolved over the years to interface
with many different types of news- or mail-like backend programs,
presenting all of them using a unified interface.  This sort of
software often calls for an object-oriented architecture, at least as
regards polymorphism, yet Gnus was written well before Emacs lisp
acquired the object-oriented tools and libraries -- largely borrowed
from Common Lisp -- that it boasts today.

Yet Gnus needed something "object-oriented-like", and so nnoo.el was
born: a rather amazing (and frankly terrifying) implementation of
object-oriented behavior using functional code.

This talk will be a brief introduction to how this existing system
works, and to the ongoing, incremental effort to port it over to newer
Elisp tools like generic functions, structs, and objects.

***** Talk information

Maxima is a great tool for symbolic mathematics, it has some support
for Emacs in the main repository, but is quite outdated and doesn't
receive the love I think it should, so a couple of months ago I decide
to improve and "modernize" the maxima-mode.el code base.  So, I want
to talk about the integration with Emacs, the maxima REPL, how some of
the main tool for Emacs integrate in maxima-mode and in general show
how to start using maxima within Emacs.
