a playwright once had a line like "The reasonable man adapts himself
to the world; the unreasonable one persists in trying to adapt the
world to himself. Therefore all progress depends on the unreasonable
man".

there are not many unreasonable men of the right kind (englebart
perhaps), too many of the wrong kind, and too many reasonable men who
don't realize the need to become unreasonable until it has become too
late for them, even them personally.

that last one is why mass human rights violations sneak up on
populations and are rejected out of hand until it is too late, and,
imo trivially, why computers interfaces in the broad sense are dumb.

i don't think there is any intent behind computer dumbness except get
it out the door.  the dbas of the past could have had no intent to
create the y2k problem, just to save space.  and with that i am out of
this ot discussion :).

Please send the file lesson1.html for review, and if I find right
workflow for you, I will tell you how I have done that.

Regarding moodle, I would make lessons in Emacs, and people would
accessing them from Emacs to the central database and answering it
that way. But that is my opinion, browsers are by opinion of other
people more practical.

[O] Pandoc and Org-mode: list indention

[Devin Prater]

Hi all. I am not a programmer, but have found Org-mode useful for editing 
course lessons.
I, blind myself, teach other blind people how to use technology and software, 
along with my supervisor and quite a few others. We have many courses on the 
use of Microsoft Office, Gmail, Internet basics, and so on. These courses are 
handled by Moodle, which accepts HTML and Markdown formatted text. Why it 
doesn’t use Org-mode, which is superior to Markdown in every way, is beyond me.
So, these course lessons are awfully malformed HTML. Empty  tags, misused 
 things litter these files, and “middle dot” characters are used instead 
of  elements.
I’ve taken it upon myself to clean all this up, and Org-mode does it all. The 
only problem is, when I convert from HTML to Org-mode using Pandoc, just doing:
Pandoc -I lesson1.html -o lesson1.org 
The lists are not made into indented ones, just a paragraph, which I manually 
have to indent, marking the lines below the list marker line, and doing C-x 
C-I, then indenting 3 or four spaces, then filling the paragraph just to make 
sure.
Is there anything I can do to make this less tedious?
Other than all that, Org-mode does amazingly for everything I’ve used it for, 
so thanks so much for all who, knowing much more than I do about code, work on 
Org-mode, and Emacs in general.

[O] Feature Request: Use ~org-set-tags-command~ for ~%^g~ in capture

[Samuel W. Flint]

Hello!

Is there a way to use the ~org-set-tags-command~ function to complete
tags during capture?  It currently uses whatever my normal completion
method is, but this means that I can't use the faster tag-selection
method that I'm used to otherwise.

Thanks,

I am glad to have found that information as it clarifies what means
Internet as from its beginnings. That is definitely the first thing to
teach in computer classes when mentioning Internet.

It is also sad state that for long time the concepts were not
available to people and still are not.

The file system concept is somehow unintentionally or intentionally
hidden to common people. It is a hierarchy, a data tree, that is well
suitable for nice sorting of files, but how to sort files really is
not well explained, it is somehow lacking. For example there is not
example concept given in books or instructions of operating systems
on how to keep files. I think it would be beneficial.

So is the concept of hierarchical data management or structured data
management.

And I remember the concept of entering the links and menus already
from the BBS[1], and I do not know why and how, I remember being
isolated in former Yugoslavia, without any contact to Internet or
outside knowledge, and we were making similar menus like on the demo
of Douglas Engelbart[2] on our small replicas of TRS-80 computers.

Video conferencing is quite a large need and have been shown in movies
so many times, but is still not developed and not in use by large. Sad
situation, I was really expecting much more from the 21st century,
about 50 years after the inventions of Douglas Engelbart.

Org mode is a simple way by which one can build such augmented
information systems. But it is not as integrated.

Look at "What it offered"[3]:
> Doug's lab pioneered progressive work processes while using each

There are packages and possibilities for shared screen and
collaborative viewing, publishing on Internet and editing. I am not
sure if this is really demanded overall. But in one way or other we
have it in GNU Emacs.

GNU Emacs basically became what NLS/Augment offered and what Douglas
Engelbart envisioned

> document cataloging

Not sure about that, but software tools exist for this, maybe one such
is Orgadoc[4], and document indexers also exist. However, not well
integrated and not easily accessible to population.

> project management

We are lucky that Org mode offers project management features provided
the user knows how to start and where to start. But what about the
population? Project management shall be introduced in my opinion by
every operating system.

In fact every operating system shall be given to user with one or
other similar information management package.

For my biased needs it would be best to improve the GNU Emacs to the
level that it can boot and then offer to users options to launch other
software. 

> shared address book,

I guess that LDAP[5] and various CRM[6] related software do offer such
possibilites. We still do not have such options from GNU Emacs, I wish
we would. It is necessary for any larger organization or remote work
stations to have some kind of centralized database from which access
to shared address book would be possible.

I guess this can be easily implemented in GNU Emacs by creating an SQL
database to which Emacs work stations could gain the access.

Of course there would be no need for slow motion browsers.

This we surely have within Emacs

Emacs has this pretty much, but not as much as I would wish and
like. Hyperlinking is important feature. We cannot just link
everything in Emacs. GNU Hyperbole[7] have given the concept of
linking to many information references, but it is not as polished and
not as easy to go for common man.

> For example, you can create a link to any paragraph or line of code
> or email paragraph

That would be great. I need this feature, this would be so useful. It
should not matter which type of file it is. Not just Org files, it
should work like Hyperbole on many other files.

Version control systems exist, we have this.

This can be known today by using version control systems, including
file system ownership.

Many outlines modes exist in GNU Emacs. Org mode is one of them. I
wish Org could have some

Assume that there is file A and symlink B that points to file A. If
there is an open buffer that points to A and we

since get-file-buffer does not follow symlinks.

Re: [O] change font-size in python plots depending on context

[Thomas S. Dye]

Aloha Johanna May,

This works:

#+name: fs
#+BEGIN_SRC emacs-lisp
10
#+END_SRC

#+RESULTS: fs
: 10

#+header: :var fontsize=fs() :results output
#+begin_src python
print(fontsize)
#+end_src

#+RESULTS:
: 10

Note "fs()" instead of "fs".

All the best,

Re: [O] [week?] (was: insert date-stamp for one month)

Hello,

Uwe Brauer wrote at 16:33 on August 18, 2019:

: The problem seems to be that there is no function

Well, there is, it's called `calendar-week-end-day'.

This returns the index into 'calendar-day-name-array.  Note that the
variable 'calendar-week-start-day should be set properly (it defaults
to 0 = $SUNDAY, while I set this to 1, meaning $MONDAY).

This will only get you as far as computing the name of the day.
Computing a date and/or timestamp for an instance of that day name
relative to a date is quite another matter.  The file
calendar/time-date.el might provide useful stuff for doing so.

Re: [O] change font-size in python plots depending on context

Hi Johanna,

> chapterwise or the whole book. And just as with tikz (latex) I want the font

What I do, for a similar use case, is to define values using properties
and then extract these values with a little function I wrote (see
below).  For example,

#+begin_src org
,#+property: myvariable 10
...
,#+begin_src ... :var v=(esf/get-parameter "myvariable")
... (use v in here)
,#+end_src
#+end_src

The esf/get-parameter function is:

#+begin_src emacs-lisp
  (defun esf/get-parameter (p)
(let ((value (org-entry-get (point) p 'inherit)))
  (message "parameter %s value obtained %s" p value)
  (if value
  (if (string-match-p "^[-+ ]*[[:digit:].]+$" value)
  (string-to-number value)
value)
(error "Property parameter \"%s\" not known." p
#+end_src

I'm sure there are better ways but this is what I have developed
organically over the years...

HTH,
eric

[O] change font-size in python plots depending on context

[johanna . may]

Dear org-mode fans,

I have various files that go together in one document, either
chapterwise or the whole book. And just as with tikz (latex) I want the font
size of python plots to change automatically when the context changes.

So I tried to define a variable in one of the header files like this:

#+name: fs
#+BEGIN_SRC emacs-lisp
10
#+END_SRC

I also tried to define it like this

#+name: fs
#+begin_src python :results output :session :exports none
fontsize=10
return fontsize
#+end_src

And then, in another file (that is being included by the header file) I
added :var fontsize=fs to the header and replaced the number by this
variable. I understand it complained that fs could not be found if I
used C-c C-c directly to test, since apparently the variable fs only
belongs to the other buffer (This is the first problem).

However, it doesn't work either when I compile everything (the second problem). 
Probably it
is also possible to solve this with some function in elisp. But, I have
to admit, that I haven't started learning elisp yet.

Does anyone have a solution to this problem? Any hints to helpful blogs
or stackexchange pages would be appreciated. I did a search but probably
not using the right keywords.

Thanks!

J
