This is for all of the little things I forget to do even though I shouldn't.

Make firefox default x-www-browser

• Unpack firefox in /opt
• # update-alternatives --install /usr/bin/x-www-browser x-www-browser /opt/firefox/firefox 100

Resize the damn root LVM

• Boot into a LiveCD

THIS IS FOR YOU, Aura.

So, you said you want a file like this?

These are your level, exp, whatever respectively.

MySQLdb is a Python wrapper around _mysql written by Andy Dustman. This wrapper makes it possible to interact with a MySQL Server performing all sorts of DDL and DML statements. I began my Python journey recently and stumbled at the installation of the MySQLdb module install. I was keen not to jump at an apt/yum installation as we have servers that have no outbound connections I decided I wanted to build the module from source.

You can download the MySQLdb files from SourceForge (70kb)

When downloaded you need to prep before your system is ready to build the file. Here are some prerequisites that will make life easier for you. I performed this particular install using an Ubuntu 10.04 64bit OS.

Before you start ensure you have the following installed (MySQL isn't actually required but for local Python development it's nice to have a database server to develop against!)

• MySQL Server. I used the MySQL Community Server Version 5.1.49
• gcc - The GNU Compiler

Python Ruiners

Here are some quick and easy ways to ruin Python scripts with only a few lines. Note, not all of them are Pythonic!

Of course, they only work if people are bad and use if this == True, or if this is True.
