No Entropy Left

I urgently needed a random sequence of 16-bit. I decided to collect some entropy from the Internet. Isn’t it weird I came across the following sequence several times: 09F911029D74E35BD84156C5635688C0 ? I decided to generate one myself. I did so and found out that number generated was the same. Veselin Kolev seems to have experienced the same problem.

It turned out that it’s a global problem. Some large companies involved in Digital Restriction Management (oops!) have generated the same sequence some time ago and seem to have incorporated its use in their audio, video & document reading/processing hardware… How unfortunate ! No more entropy. Physics is dead. :)
