[O] Bug: python code block single import line [9.0.9 (release_9.0.9-754-g940c90)]

[Paul Stansell]

Hello,

When executing the python code block

  #+begin_src python :session python1
import numpy as np
  #+end_src

I get this error in my python buffer

Re: [O] Tracking Interruptions -- Work Flow Question

[Bob Newell]

Solutions to the interruption problem are definitely individual. In my
case I simply tracked frequency of interruptions. I got from that the
bottom line that I should not try to work at home--- a conclusion that I
probably needed no software support to justify.

When I switched to working at libraries and coffee shops, the issue
became one of focus, and the pomodoro method solved that problem for
me after a little fine-tuning of work and break intervals.

I use one of the non-org pomodoro packages also, but it's all according
to how you organize your work.

I only think tracking length of interruptions adds value if you bill
clients in time increments, and even in that case clocking out of the
billable task is arguably more important than clocking in to the
interruption task.

If you want to know how much time is lost to interruptions, etc., just
subtract your logged productive time from the length of your workday, to
get the same depressing result as if you had logged all interruptions.

Re: [O] Tracking Interruptions -- Work Flow Question

[Tim Cross]

One of the problems with the many recommendations for productivity
techniques is that they can never really take account of the endless
number of differences in workflows, working environments and personal
preferences. For me, I found the GTD approach was geared more towards
the procrastination problem (washing windows rather than doing taxes)
and Pomodoro was more about managing interruptions you have been
conditioned to respond to (phone, email) or from colleagues/bosses.

My own journey has resulted in taking some ideas from both
approaches. It is still and work in progress and probably always will
be.

It sounds like your on the same road I was on. The one warning I would
make is that unless you can also do something about managing those
interruptions, just tracking them will likely only make matters
worse. It is even more depressing being able to measure the amount of
lost productivity or interruptions if at the end of the day you cannot
do anything about them. This is where I found the Pomodoro approach
better than GTD. I found GTD was really about organising your work so
that you were more efficient. The pomodoro approach on the other hand
has some concept about managing your environment. It recognises there
will always be people in your environment that are important enough to
be able to interrupt you at any time. However, it also highlights that
many of your interruptions are not from this group and provides one
technique to help you set expectations and agreements within your work
environment which helps everyone.

There is a pomodoro mode for org, but I preferred to use an external
program with a big clear timer. Initially, I used an old monitor and put
the timer on it and set the monitor so that anyone who came to my desk
could see it. When people interrupted me, I would say "Sorry, I'm in the
middle of something important, can you come back in x minutes (x =
coutdown on monitor) or send me an IM/Email and I will look at it in x
minutes.  While it took some time, people soon understood and would even
come to my desk, look at the monitor and then leave without saying
anything, coming back x minutes later instead. 

After me doing this for a while, a number of other staff started to do a
similar thing and now there is greater acceptance of the idea that you
don't just walk up and interrupt someone. We actually had some cultural
change where people now send an IM instead of walking and directly
interrupting someone. More importantly, they don't expect an instant
response to the IM or email.  

There is a relatively inexpensive book (paper, ebook and audio)
available from Pragmatic Pub which is relatively short and has some good
ideas. I would recommend looking at that and try out the org-pomodoro
package for a while to get a feel for it. It probably won't be quite
right, but may give you some ideas.

Tim

Re: [O] Tracking Interruptions -- Work Flow Question

[Raymond Zeitler]

Yes, I like your setup with org-capture.  I think I can overcome the problem of 
invoking the capture when someone pops in to complain that email is down, for 
example.  I would use either AutoHotKey (I'm on Windows) or bind a function key 
in Emacs to a taskerruption function for F2F issues.  One or two keypresses 
(ALT-TAB F12), under those circumstances, would not be considered rude in my 
environment.
I used Planner for several years.  It had (has) a time-warp function so that 
the user could create content retroactively.  If all else fails, I could 
schedule the taskerruption retroactively using a similar function in org.

I do.

I have set up capture templates for phone calls, mail read/write, and
general journal log. The former two, I clock-in automatically, the
latter one, manually, in case I just want to log something in the course
of my current activity.

I use tags to identify phone calls and mails, so I could sum up their
time, comparing to the whole. I don't do it though. Maybe that's why I
didn't tag my "general log journal". But to achieve what you want,
that's what I would do.

When I handle a phone call or mail or general interruption, I usually
keep the clock running until I managed all actions related to it
(e.g. summarize the phone call, and scheduling any actions resulting
from it), so rather than the interruption itself, I keep track of the
whole time to handle it. It doesn't take into account the context
switching however, as pointed out by Eric.

As for the time to trig the capture... For mails, there are obviously no
problems. I am eager to have my mu4e setup running to link directly to
the content at the same time. For phone calls, the bell is ringing up to
3 times, so it's ok. It's when somebody comes in that it's a bit tricky
to handle, because people expect your attention. I usually focus on the
need to take notes to have the opportunity to start my template, where I
just write write down a summary of what is said during the talking.

I have/had similar problems with hebrew. I attach two screenshots.

The fonts which seems to display hebrew correctly in the setting
discussed, but is quite ugly is:

(defun my-hebrew-emacs-etl-set-240 ()
  (interactive)
  (set-face-font 'default "-etl-*-*-*-*-*-*-240-*-*-*-*-ISO8859-8"))

It seems however that arabic is better displayed with

(custom-set-faces 
   '(default ((t (:family "DejaVu Sans Mono" :foundry "unknown" :slant

Re: [O] Tracking Interruptions -- Work Flow Question

[Raymond Zeitler]

Yes I see your point.  Maybe it's too ambitious to determine productivity.  But 
knowing how much time is spent on the interruption (taskerruption) would be a 
good start.

Seems to me the danger of interruptions is not how much time they take
up, but how much time it takes you to recover from them, and get back to
work. Much harder to clock!




   

[O] Bug: Explicit <6> table column width [9.0.9 (release_9.0.9-754-g940c90)]

[Paul Stansell]

Hello,

I think there might be a something wrong when explicitly setting a width
of a table column.

For example, for this table

  |---+--|
  |   | <6>  |
  | 1 | one  |
  | 2 | This is a long chunk of text |
  | 3 | three|
  |---+--|

when I press  in the table the view changes to

  |---+--|
  |   | <6>  |
  | 1 | one  |
  | 2 | This i |
  | 3 | three|
  |---+--|

and when I press C-c the view toggles between

  |---+|
  |   | <6>|
  | 1 | one|
  | 2 | This is a long chunk of text |
  | 3 | three  |
  |---+|

and

  |---+--|
  |   | <6>  |
  | 1 | one  |
  | 2 | This is a long chunk of text |
  | 3 | three|
  |---+--|


Based on previous versions of org mode, I expect to see

  |---+|
  |   | <6>|
  | 1 | one|
  | 2 | This=> |
  | 3 | three  |
  |---+|

and

  |---+--|
  |   | <6>  |
  | 1 | one  |
  | 2 | This is a long chunk of text |
  | 3 | three|
  |---+--|


Thanks,

Paul

https://emacs.stackexchange.com/q/30495/2443


Look forward to your feedback. Best Regards.


I'm afraid that I cannot offer any real help, but since nobody else has  
answered yet, I'll throw out a few thoughts. Bear in mind that I do not  
speak or read Arabic, and that my knowledge of the language is restricted  
to being able to recognize three or four of the letters and to being able  
to say Salaam aleikum.


I'm afraid that the problems are inherent in the usual presentation of  
Arabic text, in which the form of each letter can vary depending upon  
context. It seems that some people are working on trying to invent better  
"monospaced" versions of the alphabet, but those all look clumsy, even to  
their inventors, and especially so to people who are already conditioned  
to see the beauty of handwritten Arabic. Your mention, elsewhere, of the  
related problem of Japanese text seems appropriate. In Japanese, the use  
of kanji, rather than kana, can be seen as more artistic and proper, and  
the use of non-standard kanji is regarded by some as "intellectual". (Some  
would say that the more esoteric Chinese characters you know, the smarter  
you appear to be.)


You thus have in front of you a problem as large as you might wish. Think  
of it as an opportunity. You can design additional Arabic fonts, and  
campaign to make them popular. You can develop extensions to emacs to  
handle whatever versions of Arabic text you wish, including the  
omnipresent need for dealing with "mixed" text where Arabic and other  
languages occur together. In particular, you can create your own  
extensions to org mode. I'm thinking that a better set of rules for  
positioning the elements of a table need to be defined. We'll help you (a  
little bit) with the lisp. The difficulties, although huge, are not  
insurmountable. Slightly more than half a century ago the idea of using  
computers to handle Arabic text in any way at all was regarded as  
ridiculously complicated. Now it's merely complicated.


You might think, "This answer does not even begin to touch the problem. It  
omits the distinction between the identity of the character and its  
presentation. It omits regional substitutions. It omits nearly  
everything." You're right. I've provided many words, and very little help.

This makes sense and works. Thanks. It would probably have helped if I had read 
the Property syntax section of the manual more closely.

You cannot have multiple identical properties in the same property
drawer.

You could try

 :export_html_head: line 1
 :export_html_head+: line 2

I do.

I have set up capture templates for phone calls, mail read/write, and
general journal log. The former two, I clock-in automatically, the
latter one, manually, in case I just want to log something in the course
of my current activity.

I use tags to identify phone calls and mails, so I could sum up their
time, comparing to the whole. I don't do it though. Maybe that's why I
didn't tag my "general log journal". But to achieve what you want,
that's what I would do.

When I handle a phone call or mail or general interruption, I usually
keep the clock running until I managed all actions related to it
(e.g. summarize the phone call, and scheduling any actions resulting
from it), so rather than the interruption itself, I keep track of the
whole time to handle it. It doesn't take into account the context
switching however, as pointed out by Eric.

As for the time to trig the capture... For mails, there are obviously no
problems. I am eager to have my mu4e setup running to link directly to
the content at the same time. For phone calls, the bell is ringing up to
3 times, so it's ok. It's when somebody comes in that it's a bit tricky
to handle, because people expect your attention. I usually focus on the
need to take notes to have the opportunity to start my template, where I
just write write down a summary of what is said during the talking.

Re: [O] Tracking Interruptions -- Work Flow Question

[Tim Cross]

I'm not sure there is any *good* way to track interruptions. As
pointed out by others, interruptions are not equal and the actual length
of the interruption is not necessarily a good reflection of the actual
impact to your productivity.

I've found two things which have helped me. One has helped to reduce the
interruptions and the other has provided some (minimal) help when I've
been questions on why a task has taken longer to complete than
estimated.

The first has been to use a type of pomodoro technique. Essentially, I
break my work up into blocks of time where I will not answer the phone,
email or anyone coming to my desk. I do run a timer which ticks down and
/allow/ interruptions in breaks between 'pomodoros'. The timer is really
useful as when someone comes to interrupt me, I can say, come back in x
minutes. It takes some training of your work colleagues, but they will
eventually respect your request (and being able to give them a definite
'come back in x minutes' helps).

The second thing I do is if an interruption cannot be avoided, I do
check out of my current task and only check back in once the
interruption has finished. While this doesn't tell you how much
productivity was actually lost by the interruption, you can at least do
some analysis of the clock times and show how often and for how long you
were interrupted - or at least working on that task was interrupted.

yepp. Maybe add a 'braininess' factor to every task. Tasks, that need a
lot of thinking, let's say hacking, have a higher 'braininess' than, for
instance, sharpening pencils. Depending on the 'braininess' of the
interrupted task add another 15 or 30 minutes to the interruption
account.

[O] [Feature Request] Provide a way to jump to noweb reference definition under point

[numbch...@gmail.com]

For example I have an Org buffer like this:

```org
#+NAME: define food-journal
#+BEGIN_SRC clojure
(def food-journal
  [{:month 1 :day 1 :human 5.3 :critter 2.3}
   {:month 1 :day 2 :human 5.1 :critter 2.0}
   {:month 2 :day 1 :human 4.9 :critter 2.1}
   {:month 2 :day 2 :human 5.0 :critter 2.5}
   {:month 3 :day 1 :human 4.2 :critter 3.3}
   {:month 3 :day 2 :human 4.0 :critter 3.8}
   {:month 4 :day 1 :human 3.7 :critter 3.9}
   {:month 4 :day 2 :human 3.7 :critter 3.6}])
#+END_SRC

#+BEGIN_SRC clojure
<>

(take-while #(< (:month %) 3) food-journal)
#+END_SRC
```

The point is at `<>`. Hope org-mode can provide and
shortcut to jump to noweb reference definition `#+NAME: define
food-journal`.

[O] babel, matlab export plot to png fails

[Uwe Brauer]

Hi

I would like to execute some matlab code in org file (using GNU emacs 26
and the git version of org mode) and save the result of the plot command
in a png file, so I tried

#+begin_src matlab :session :exports both :file testplot.png
t=[0:0.1:1];
y=sin(t);
plot(t,y)
print -dpng  testplot.png 
#+end_src

And also
#+begin_src matlab :results output latex :exports results  :file testplot.png
t=[0:0.1:1];
y=sin(t);
plot(t,y)
print -dpng  testplot.png 
#+end_src

But the resulting png files are corrupt. I presume also the matlab
commands are included in the png file which is not correct. But I don't
know who to achieve that just the last command is saved in a png file.

I googled without success. Does somebody know the correct syntax?

Thanks

Uwe Brauer

[O] Bug: Babel result block '#+end_example' not indented [9.0.9 (release_9.0.9-748-g3359e0 @ /Users/xcy/src/org-mode/lisp/)]

[Chunyang Xu]

For example (noticing the last line '#+end_example' is not indented with
two space)

* test
  #+BEGIN_SRC sh :results output
  seq 10
  #+END_SRC

  #+RESULTS:
  #+begin_example
  1
  2
  3
  4
  5
  6
  7
  8
  9
  10
#+end_example


By reading the source code, I think 'indent-rigidly' doesn't the correct
end bound so the last line is not indented

(defun org-babel-insert-result (result  result-params info hash lang)
  ...
  (org-babel-examplify-region beg end results-switches inline)
  (setq end (point))
  ...
  (indent-rigidly beg end indent)
  ...
  )

'org-babel-examplify-region' wraps the result within
#+begin_example..#+end_example but doesn't move the point forward by one
line because of using save-excursion.

I attach a patch which uses the marker 'end' to track where the result
block ends, instead of (point). I have tested it against Emacs
24.5 and 25.2 slightly.

[O] Org table: reuse formula in non-rectangular range

[Jarmo Hurri]

Greetings.

I have a situation where I need to use the same table formula all over
the place in a table. The problem is that "all over the place" is not
rectangular - if it were, this would be trivial.

I can see two possible solutions, but I don't know if either of them is
possible in Org.

1. A non-rectangular range on the left hand side of a formula. This
   would be the best choice if it were available.

2. The possibility to create a shorthand (macro) for the formula so that
   it would be easier to reuse the formula in a large number of
   rectangular ranges.

Is either of these feasible?
