		<description><![CDATA[Easy. Short of.
I did this &#8216;experiment&#8217; to test how much cross-platform Qt really is. I wanted to see if SocNetV can run on Maemo with no modifications whatsoever. These are the steps I followed:
1. Downloaded and installed the Xephyr X11 server (this is a small X11 server that runs inside &#8216;normal&#8217; X and  provides [...]]]></description>

		<description><![CDATA[Simple. At least in Debian, Kubuntu and other Debian-derivatives. Install Samba server and the appropriate KDE4 module as root:
# apt-get install samba kdenetwork-filesharing
The kdenetwork-filesharing package installs a nice System Settings panel to configure network file-sharing using NFS and Samba. It also adds (the initially missing) functionality in the Properties &#62; Share tab of each file [...]]]></description>

		<description><![CDATA[Just use the fabulous command REPLACE provided by mysql. The syntax goes like this:
update database_table set table_column = replace (table_column, "oldstring", "newstring");
For instance, to replace all occurrences of &#8220;modules&#8221; inside the linuxformat.gr drupal db with &#8220;sites/all/modules&#8221; I typed in:
update linuxformat_system set filename = replace (filename, "modules", "sites/all/modules");

		<description><![CDATA[Name-based virtual hosting enables us to serve different domains from a single server. All we need is to add this line to /etc/apache2/sites-available/default:
NameVirtualHost *
The * specifies that Apache will serve requests for all IP addresses; optionally we can specify only a certain IP on the server.
Next, we create a new  for each different domain [...]]]></description>

Despite my eagerness to update my N900 to Maemo 5 v10.2010, the software update tool kept giving me the following cryptic message:
&#8220;not enough memory in target location&#8220;
Wtf? The message was a surprise for me, since I thought the 32GB of my N900 would be more than enough [...]]]></description>

The new graphical theme, designed and implemented by yours truly, plays with the notion of recipe notes pinned on a corkboard. The frontpage &#8216;carousel&#8217; is still the old one, but it somehow fitted nice.&#160; I am not a designer [...]]]></description>

This device runs Linux on an ARM Cortex 600MHz CPU, 1GB RAM and 32GB HDD, and it is more a portable computer than a mobile phone, thanks to its 3.5&#8221; touch screen (800&#215;480 resolution) and the embedded keyboard. Right now, my N900 is still charging (minimum [...]]]></description>
