Have to agree with you there, what the hell is the point in that?
That's wrong. It is extremely inefficient. On many filesystems, it uses 4096 times as much space as it claims, for example.
So what byte value is it?
Haha! That guy has some interesting photos too... the "Portraits de Toilette" section is rather amusing.
1byte... a single 0x0D (carriage return).
