If you click here you'll find some links to my colleague who is really into fulhacks.

More about the Fulhack concept:

And remember these old but simple hackers' rules:

• Do no harm
• Respect private property
• Share what you learned
• Backup your stuff
• A nanosecond's optimization is worth a hundred lines of incomprehensible code
