I was just researching on how the file format of the xt_recent module works.
That's where I found this nice easter egg: instead of writing down the size of
an IPv6
address plus one,
they simply used a dummy string +b335:1d35:1e55:dead:c0de:1715:5afe:c0de", reading "beesides less dead code it is safe code".
Hehe.
