Hi, I am an enthusiastic emacs-org user. Thanks for making this great
tool! I gave a talk on emacs-org in a local workshop (Government Advances
in Statistical Programming) in Washington D.C. yesterday. I'd like to
share the slides and org source file with the community (see attached).
Please help. Thanks!
Sincerely,
Feiming Chen

I have already learned some cool org-mode features by looking at your .org
file :-)
My own mantra for preparing slide-packs is to minimize text. I want the
audience to listen to me rather than reading text on my slides.
My 2 cents...

please don't overdo that.
People have quite different ways of taking in information. Some memorize
best if they hear something. Others memorize best if they have visual
input. Others memorize best if they somehow take that information into
their hands (for example by writing).
If all you give is auditory input, you will leave a lot of interested
persons in your auditory in the cold.
My 2 cents...

Thanks for sharing!
I wonder why you stress the following:
- Not good for collaborative use (unlike Microsoft Office).
- Good for private, non-collaborative use.
My view is the opposite: Org mode is excellent for collaboration as
it is plain text, suitable for diff/merge in Git repositories.
Thanks to the separation of contents from style,
cross-organizational collaboration is possible, which I find *very*
hard with any office tool: Changing a document master leads to all
kinds of layout destruction. Switching to a different corporate
identity is just hard with what-you-see-is-what-you-get tools.
In contrast, Org mode can be a basis for what is called Single
Sourcing [1] in the context of technical writing.
You can see my approach towards Open Educational Resources with Org
mode at [2].
Best wishes
Jens

There is always a balance to be achieved, in my experience. The trick
is to have slides that support you but do not compete. If there is too
much text, the audience will be tempted to read and will not be paying
attention to what you say. I tend towards Martin's view with little or
no text on many slides but slides with text will be limited to 3-4
bullet points and each bullet point having 5-6 words maximum. But, of
course, this all depends on your intended audience.
In any case, in the spirit of this thread, please find attached a
presentation (both PDF and original org file) I gave earlier this year
to an academic audience consisting mostly of mathematicians and
numerical analysts. The topic was literate programming but it was
really about org and Emacs. Lot of interest from the audience and I
hope I converted some to this eco-system.

#+title: Literate programming and reproducible research
#+author: Professor Eric S Fraga, UCL
#+macro: lastchange 2018.06.06 10:36
* Introduction
** The aim & challenge
*** Reproducible research
To ensure that our research is *reproducible* both by ourselves and by others.
*** Coding, processing, writing
In doing research,
1. we all *write* programs ...
2. which generate *results* ...
3. which need to be *processed* ...
4. and which should be *disseminated*.
Currently, we use different tools for each step.
*** Tools
Workflow:
- coding :: IDE, MATLAB editor, ~vi~, ~notepad~, ...
- results :: ~.txt~, ~.xls~, ~.dat~
- processing :: spreadsheet, ~R~
- dissemination :: ~Word~, ~PowerPoint~, LaTeX, ~beamer~
- project management :: ?
leading to constant *transfer* of data from one place to another.
** Literate programming
*** Definition
#+begin_quote
Literate programming is a programming paradigm introduced by Donald Knuth in which a program is given as an explanation of the program logic in a natural language, such as English, interspersed with snippets of macros and traditional source code, from which a compilable source code can be generated.
#+end_quote
https://en.wikipedia.org/wiki/Literate_programming
*** Code and documentation
#+attr_latex: :width 0.8\textwidth
[[file:literate-programming-tangling.png]]
[[http://howardism.org/Technical/Emacs/literate-programming-tutorial.html][Source]]
*** Example: the Strawberry algorithm
[[file:strawberry-outline-withborder.png]]
[[https://www.ucl.ac.uk/~ucecesf/strawberry.html]]
** Emacs
*** Editor
- originally written in 1976
- content aware editing
- fully extensible in ~Emacs LISP~
- self-documenting with comprehensive help system
- large eco-system of packages
https://www.gnu.org/software/emacs/
*** org mode
Text (*it's all text*) based mode for
- writing & dissemination
- project management
- literate programming
https://orgmode.org/
* org mode
** Programming
*** Example objective function
\begin{align*}
\min_x z &= \sum_{i=1}^{n} x_i^4 + x_i^3 - 2x_i^2 \\
x & \in [a,b]\cap\mathbb{R}^n
\end{align*}
*** Plot of objective function
#+results: plot-f
[[file:f.png]]
:plotcode:
#+name: plot-f
#+header: :term "png crop"
#+begin_src gnuplot :file f.png :exports results
reset
set cntrparam levels 40 bspline
set contour base
set hidden3d
unset key
set view 60,326
set xrange [-2:2]
set yrange [-2:2]
unset xtics
unset ytics
unset ztics
unset zlabel
splot x**4+y**4+x**3+y**3-2*x*x-2*y*y
#+end_src
:end:
*** Tangling
Create an ~octave~ file with the objective function using *tangling*:
#+name: octave-f
#+begin_src octave :tangle "f.m"
function [z g] = f(x)
z = sum(x.^4 + x.^3 - 2*x.^2);
g = 0; % unconstrained
endfunction
#+end_src
*** Code segments
Specify the parameters for the optimisation problem:
#+name: problem-setup
#+begin_src octave :noweb yes
n = 2;
x0 = rand(n,1);
a = -2*ones(n,1);
b = 2*ones(n,1);
#+end_src
*** Bringing bits together
The code to include the problem setup directly and solve the problem:
#+name: strawberry
#+begin_src octave :results value :noweb yes
clear
format short
<<problem-setup>>
[x y] = strawberry(x0, a, b, @f, 10, 10);
[x;y]'
#+end_src
:results:
#+name: strawberry-results

** Writing
*** Outlines
Example (a recent paper):
[[file:impact-paper-outline.png]]
Can show, hide, and move individual sub-trees.
*** COMMENT Content
- export can handle mathematics:
\[ y = \sqrt{x} \]
- figures:
[[file:~/s/personal/avatar-australia-hat-sunglasses-64x64.png]]
- tables (as we have already seen) but with formatting:
| Item | Description |
| <l> | <r> |
|------+-------------|
| One | Interesting |
| Two | Boring |
*** COMMENT Inline LaTeX for full control
- We can include inline LaTeX directives.
- For instance, \fbox{in a box} would output as you expect.
*** Publishable output
~org~ will *export* to LaTeX (and hence to ~PDF~) or ~ODT~ (~MS Word~ compatible).
[[file:odt-export.png]]
*** Project management
Support for tasks, scheduling, appointments:
**** TODO [3/4] prepare and give presentation on literate programming
DEADLINE: <2018-06-06 Wed>
- [X] collect images
- [X] write slides
- [X] book hotel
- [ ] give presentation
*** Revision control
- A research project is a long term activity comprised of many individual tasks.
- Revision control should (*must*) be an integral element of project management.
- Think *track changes* but on steroids and which works for *data* as well.
- Excellent tools exist: ~git~, ~mercurial~, ~subversion~, ...
*** Example of revision control
[[file:hg-log-view.png]]
* Conclusions
** Summary
*** Emacs & org
Single tool for *writing*, *coding*, *data manipulation*, *data provenance*, *dissemination*, and *project management*.
*** Testimonial I
#+begin_quote
By the age of 35 you should have realized that Emacs is the One True Editor and should have embraced it. If that’s not the case - your life so far has been completely wasted.
#+end_quote
[[https://twitter.com/bbatsov/status/998217369204948992][@bbatsov, 04:02 pm May 20, 2018]]
*** Testimonial II
#+begin_quote
The advantages of plain text are hard to overstate, as is the advantage of having everything from plot notes to research material in a single (large) file under version control. And building up a novel from an outline is a natural process with org-mode.

Hello,
This LaTex code to put before \begin{document} :
\AtBeginSection[]{\begin{frame}<beamer>\frametitle{}\tableofcontents[currentsection,hideothersubsections]\end{frame}}
is very useful, because it recalls the steps of your presentation and
focuses on the current section.
I hope that helps.
Best wishes,

Jo

Thanks, Jens, for your comment! I understand your point of view! My point
is that Org mode is not ubiquitous and most people (esp. non-programmers)
do not use emacs. But I do concur that Org mode is great for
collaboration IF a team can agree to using it.
Thanks for your interesting references! I am glad to learn about "single
source" and OER. Your OER material looks fascinating: I don't know that
.org file can be rendered instantaneously as HTML on GitLab.
