"Water, in all its forms - rivers, lakes, falls, clouds, rain, and, most of all, life, is a source of never ending beauty."
" 'Life' is software that builds its own hardware."
"We are living the first pass of a two-pass algorithm."
"We do not learn; we discover what we did not realize we already knew."
"BIRTHDAY: that special day of the year that most clearly marks that Time pushes the start of our life farther away, and pulls the end nearer."
"The best way to get something programmed is to ask a programmer to do it by hand."
Whether you add (BU__SH__) or subtract (B_S_), the result is the same.
He is now out of office (thank goodness), but we must not forget the horrors of those eight wasted years. Inform yourself about BU__SH__
