Install multiple OS Without Cds
Orig published 2006. I had a CD-RW drive but being a computer security researcher I had no money for blank cd-recordables. What follows is how I managed to install various operating systems on my computer (1 hard drive) without having to burn to a CD the ISO and then boot from that.

Add CSS Class to body when Sidebar is Present
Here's the problem I was having while working on a custom theme for a client. Certain pages, posts, tag pages, archive pages, and custom pages either had the sidebar, or did not have the sidebar. The main content div #ContentW had a 72% width when the sidebar was present, otherwise it was 96%. The problem was that I dislike having to do things manually when they can be automated through code. What I was having to do was manually add/remove page-specific classes to the css file to reflect whether the sidebar was present on that page or not.
Show or Hide WordPress Admin Bar Plugin
The Admin Bar in WordPress is always shown when in the backend administration area no matter what.
You are given the option to show/hide the admin bar when viewing the site, but there is no option to show/hide the admin bar when using the backend... So I created a plugin to provide that option on profile pages.
Why hide the admin bar in backend?
Normally I like the admin-bar and usually have it enabled, but it's nice to be able to switch it on/off from the "Edit Profile" page. The biggest reason for not loading/showing the admin_bar in the backend is SPEED. Here are 2 instances where I hide it-

AskApache Password Protection, For WordPress
AskApache Password Protect adds some serious password protection to your WordPress Blog. Not only does it protect your wp-admin directory, but also your wp-includes, wp-content, plugins, etc. plugins as well. Imagine a HUGE brick wall protecting your frail .php scripts from the endless attacks of automated web robots and password-guessing exploit-serving scripts.
Preload flash .flv files into browser cache
How I was able to preload many flash flv and swf files on one of my clients sites that has a lot of online video and relatively small traffic. Their site visitors would usually watch 3-10 videos per visit and so to make the videos load almost instantly on every page I came up with a way to preload the top 10 .flv files and the swf flv player files as soon as the visitor successfully started watching the 1st video. Of course I also setup .htaccess caching on the server so that once they downloaded the files into their cache they would never request them from the server again. I was having fun with this so its pretty funky and uses some really cool combinations of javascript, swf preloader from xml, css classes to help automate it all..

View all MySQL Variables for Pasting into my.cnf
This is really useful for me because I work with dozens of different database servers. The first thing I do is run this command and paste it into the servers /etc/my.cnf file. That way I will always know the original value and it just makes life much easier.

COMPUTER SECURITY TOOLBOX
List of mainly obscure security software geared more for the master pentester. These are mostly for unix, bsd, and mac and many are difficult to install and setup (require custom servers, inside access points, obscure libraries). Only programs that output data are included, so no actual exploits or anything. Most of these output extremely useful albeit extremely technical information.FastCGI on DreamHost

Notes from Apache HTTPD Source Code
thought I'd take a break from coding and post about how open-source is such a great tool for finding the best answers to the toughest questions,

Automated Folder Backup Shell-Script
This simple unix shell script automatically creates backups of a specific folder at regular hourly, nightly, weekly, and monthly intervals. Instead of the usual method for copying directory trees using tar with fifo, pipes, rsync, or NFS methods this script uses cpio which is much much faster and has cool options like saving m/a/c times, symlinks, relative paths, and weird file names.

.htaccess trick to show Alternate CSS file based on IP
