		<title>How to get Emacs key bindings in Ubuntu</title>
		<description><![CDATA[To get the Emacs key bindings (especially, Ctrl-a to go to beginning of line, Ctrl-e to end of line) systemwide, e.g. in Firefox, you use:
gconf-editor
and change the setting desktop &#8594; gnome &#8594; interface &#8594; gtk_key_theme from &#8220;Default&#8221; to &#8220;Emacs&#8221;.

		<title>How not to ask a question on R-help</title>
		<description><![CDATA[One great way to get help with R is by asking a question on the r-help mailing list. More often than not I have actually figured out the answer simply by typing up the question, because that made me think more clearly about what the problem really was. The people on the list are exceedingly [...]]]></description>

		<title>MySQL settings in ~/.my.cnf</title>
		<description><![CDATA[You can specify default settings for MySQL in the file ~/.my.cnf (create it if it doesn&#8217;t exist). E.g., you could spare yourself typing your password each time you connect with an entry in that file like this:
[client]
password='mypassword'
This gets loaded in addition to the system configuration file, which for me is at /etc/mysql/my.cnf.

		<title>Use R to help with lottery drawing</title>
		<description><![CDATA[When you start using R, it can be confusing that if you assign something to an object you do not get visual feedback:
x  x
 [1] 1 2 3 1 2 3 1 2 3 1 2 3 1 2 3
You can exploit this fact for doing a quick-and-dirty lottery. Assume you have a file [...]]]></description>

		<title>Small hyperref error solved</title>
		<description><![CDATA[For the record. I got an error running hyperref:
Paragraph ended before \Hy@setref@link was complete
This was due to having a regulare closing parenthesis directly after the curly bracket that closed a \ref, like this: (see section \ref{section-1}). Putting in a space between the closing curly bracket and parenthesis solved the problem: ... section-1} )

		<title>Nice R example from r-help</title>
		<description><![CDATA[I don&#8217;t know the first thing about programming, but sometimes you see something and appreciate how elegant it is. This small solution from r-help is a good example. Someone wanted, given a vector c('p','p','t','t','t','p','k','t') to produce NA NA 1 2 3
