0x1A4 

Hexadecimal for 420. This number can often be useful as a testing value when writing simple or not-so-simple programs on a computer, but more often indicates that it's time to pack a bong full of kush and burn it first to see if genuine value can be derived from such an effort.

This hydroponic management program just threw another Exception 0x1A4 when I tried to simulate growing with a second lighting system, this is hella bunk!
