왜 이렇게 모든 것이 불안할까

알 수 없다. 왜 무엇이든 불안한지. 

독일어 공부를 하다가도 아무 것도 머리에 남지 않을 것 같아서 불안하고, 폰도씨랑 결혼에 필요한 문서를 준비하는 것도 뭐가 잘 안 될까봐 불안하고. 한국에 있을 때 왜 아무 준비도 안했었는지 불안하고. 

Org mode, resize inline-image without installation of ImageMagick in window

Place the ImageMagick portable in a certain directory and use the convert command as

d:/emacs/bin/ImageMagick/convert

Add following script in .emacs
and then it will generate width: 800pix temp-image under _filename.png and shows in org-mode.

(require 'ox)

(defun org-display-inline-images (&optional include-linked refresh beg end)
  "Display inline images.
Normally only links without a description part are inlined, because this
is how it will work for export.  When INCLUDE-LINKED is set, also links
with a description part will be inlined.  This can be nice for a quick
look at those images, but it does not reflect what exported files will look
like.
When REFRESH is set, refresh existing images between BEG and END.
This will create new image displays only if necessary.
BEG and END default to the buffer boundaries."
