Surely by now you’ve seen the video where NextGenHacker101 shows you how to use the “Tracer T” program to view “how many IP’s are looking at Google”, their name, and connection speed (to then to then to then). (And commenter squizz explains why it “worked” in spite of the http prefix.)
But more awesome is the fact that somebody ported the video to linux!
Bonus video craziness: It’s in Korean but somehow that just adds to the insanity. (Warning: Five minutes of your life you will never get back.)
