I just got a slight flashback to my 15 year old self sitting in front of little "crackme" programs (<a href="http://en.wikipedia.org/wiki/Crackme" rel="nofollow">http://en.wikipedia.org/wiki/Crackme</a>)<p>Nice to see that things change, but do somehow remain the same :)
I came across a USB thumb drive from when I was in highschool (freshmen), and I was embarrassed when I looked at it just recently...I was storing login credentials in a browser cookie, and not a session cookie, how insecure but I didn't know any better at the time...
