Some tools in Backtrack Linux version 5 R3 were written for older versions of Python so if you are interested in using some of these tools in can be beneficial to install older versions of Python such as Python 2.4. Below I describe how to easily install Python 2.4 without causing issues with the Python 2.6 that is installed by default on Backtrack Linux 5 R3 or Ubuntu 10.04.
Yesterday I needed to upgrade a single application on CentOS Linux. First I figured out that the application was part of the coreutils RPM package which is currently only available up to version coreutils 5.97-23 on CentOS. The current coreutils package is already up to coreutils 8.5 and upgrading coreutils is near impossible on CentOS because of other package requirements that it needs. Below are instructions on how to download the coreutils source, build the coreutils applications in a new directory, and then upgrade one application.
Notepad++ is one of my favorite applications on Windows because of all of the functionality it provides. One thing I needed to do recently was to add text to the end of each line in a text file but I wasn’t sure exactly how to do it without a little research.

I recently launched my first word press web site and had a friend tell me that a important security precaution was to change the table prefix of your word press database. The default prefix for the tables is “wp_” which can make it extremely easy for a attacker to run sql injection commands through flaws the they may find in word press. If we can change the name of a table a attacker will have to figure out that information as well thereby adding one more layer of security to our site. I was getting ready to change all the wp_ prefix’s manually when I discovered a plug in called WP Security Scan which claimed to automate the process.
