Linux memo

Encouraged by this post on Dominik's blog I installed enscript. I tested it by formatting the source of a C program, using the following command:

enscript --ps-level 2 --highlight=html --header="Listing of Johnson.c|%W|Page $% of $=" -p Johnson.ps Johnson.c

This creates a thumbnail for each jpg image in the current folder, prefixing its name with the _thb_ string. Note that the command convert is provided by the ImageMagick software suite.

Emacs: convert tabs into spaces
In order to convert the tabulations into white spaces, in Emacs, add the following line in the ~/.emacs file (in your home directory):

(setq-default indent-tabs-mode nil)

This can be useful if you want to export the indented code (for example, if you have to insert it in a verbatim environment in LaTex).

Need to work late at night?
You are confronted to an approaching deadline and you need to work during the night: luckily, there's coffee. Surfing on the web I found this interesting article:
