Normal people spend their nights watching movies, reading articles, socializing or (yes, I know it's odd) sleeping. I spend my nights reading RFCs and pentesting various applications/services.

One night I was randomly reading the tel URI scheme RFC as I am fascinated by old relics that are still used today, their flaws and the way people never read the RFC which leads to RTFM pwnage as I call it. As I finished reading the tel RFC I looked at my iPhone and said: Cool, let's try it out!. I instacoded a small html page and loaded it in Safari. As I clicked the click me link I was prompted with a nice dialog asking me if I really want to call 0000.
