Security and Obscurity

If you do not know the password but know how to use the password to gain access to something that was secured using this password, then this is security by obscurity.

Nandor's Exhaustive Chemical Words Pages

Few days ago I wrote about pangrams and today I saw in Slashdot another way to play with words – build them from chemical symbols.

Two who knows?
Two I know.

Three who knows?

Infinity who knows?
Infinity I know.
Infinite is the world.

Few years ago, there was a Linux installation party in an obscure Israeli city. The compulsory trashcan got the label “/dev/null” (it was my own proud hand which wrote those fateful letters), and when it was emptied, someone took a shot of its location and labelled it as “/dev/null unmounted”.
