This is a small script I’ve written to automate my server-side backups of my blogs. It creates a backup of both the database and the actual WordPress files.

I started developing Google Gadgets for LabPixies, so one of the first thing I looked for was syntax highlighting. Vim recognized the gadgets’ code as XML file (which is correct), but I wanted also HTML syntax highlighting for the HTML part. So after searching a bit for some existing solution, I found one, but I didn’t like as it required me to wrap the HTML code with a specific comment. As I don’t like this kind of solution, I’ve decided to create my own syntax highlighting file for Vim.

Like many Linux users, I use Guarddog as a frontend to my iptables firewall. At some point, I noticed that Guarddog started acting strangely. Every time I restarted my computer, all internet traffic was blocked (both in and out). The only way to fix this situation was to open Guarddog and press “Apply” (without doing any changes).

Sometimes svn switch fails because unversion files exist in the working copy, and the need to erase them comes up. This is also true when updating to an old revision (usually one that misses directories that exist in the head revision), doing some work (like compiling), and then trying to update back to the head revision. Subversion (SVN) will fail complaining that directories/files already exist.
