What hides between Shadow and Light?

So, I´m starting to think that the guy, who said that the "hole-digging critters" were bugs in a computer program, was right!

If that is so, a "way to track this development" would be version control software. For example, Subversion: http://en.wikipedia.org/wiki/Subversion_(software)

The same guy said that a "seed" was slang for "initial setting of some random number generating machine". Well, Thomas gave us a hint - Vernam - and googling that lead me to this encryption related article:http://en.wikipedia.org/wiki/One-time_pad

The one-time pad is derived from the Vernam cipher
