Haxxor World no longer loads because of some old, broken JavaScript. I made a Chrome extension to fix that: http://virus.game-hackers.com/hw_fix.crx
Simply open your extensions page in Chrome and drag that crx file into it. You may need to check the developer mode box at the top of the page for it to install.
If you are using another browser, here is a user script that can be used with GreaseMonkey (or a similar plugin): http://virus.game-hackers.com/hw_fix.user.js

I haven't heard anything from Pure Chaos since 2010 when he made a blog post here. He did log in about a year ago, though.
Also, nice job on your education. I actually just graduated with honors and obtained a degree in computer science.
