To replace numbers in a document with other calculated numbers (e.g. to replace a 20 with 20-10=10, and a 43 with 33), the best is to use

M-x query-replace-regexp

which is bound to

M-C-%  (= M-C-Shift-5).

Or use

M-x replace-regepx

E.g. to subtract 8 from each number in  the string

out_11_14Small.png

do the following:

M-x query-replace-regexp

[Query replace regexp:] \([0-9][0-9]\) RET
[Query replace regexp in region \([0-9][0-9\) with:]   \,(+ -8 \#1) RET

RET = press the return key.

If you e.g. want to show all blog entries with the tag "bash" when clicking on the menu tab "bash", here is what you have to do.

Install following two modules:

ctools

views

and enable views, views ui and ctools.

go to
  structure > views > add new view

  View name: bash_view
  Show Content of type all tagged with YOUR-TAG sorted by Newest first  

A list with examplary parameters of how to use the terminal function "find" (in Linux). This function can be used to find files, directories, etc. First open the terminal (Ctrl+Alt+t) and then type in one of the following commands.

This post explaines how to get highlighted code in Drupal 7 like:

for i = 1:3
   j = i;
end

For me the combination of CKEditor and the code highlighting tool Geshi did not work.

Hence I tried the combination of the module [[https://www.drupal.org/project/prettify | google code prettify]] (which is used by stackoverflow.com) and CKEditor.

Prerequisite

CKEditor must be installed. See other post for that.

Getting it to run

In short:

M-x dired-do-query-replace-regexp

Longer version:

To replace the same regexp, string or word in multiple files go into dired mode

C-x C-f RET

Then you should see a list of files.

Mark the files you want to edit with m.

To mark all files press t (M-x dired-toogle-marks).

Sometimes you don't want to display figures or plots within matlab, e.g. if running matlab with the -nodesktop flag on a remote machine, e.g.

matlab -nodesktop

Include following lines in your code or paste it in the matlab command window to disable the figures:

set(0,'DefaultFigureVisible','off');

Sometimes it is also good to include

NOTE: you should only allow anonoymous users to post comments if you have some human checking feature implemented, like the captcha module.

go to

  people > permissions

or navigate your browser to

and check

If the search bar is not showing up in Drupal, it is a permissions problem

By default the search bar is only visible for admin users. To enable the search bar for all users, go to

  people > permissions

In Emacs 24.1, there’s a command

  C-x r N (‘M-x rectangle-number-lines’)

for numbering lines.
