Outside of a dog, a book is man's best friend.  Inside of a dog, it's too
dark to read.

Over the shoulder supervision is more a
need of the manager than the programming task.

Overall, the philosophy is to attack the availability problem from two
complementary directions:  to reduce the number of software errors through
rigorous testing of running systems, and to reduce the effect of the remaining
errors by providing for recovery from them.  An interesting footnote to this
design is that now a system failure can usually be considered to be the
result of two program errors:  the first, in the program that started the
problem; the second, in the recovery routine that could not protect the
system.

Overconfidence breeds error when we take for granted that the game will
continue on its normal course; when we fail to provide for an unusually
powerful resource -- a check, a sacrifice, a stalemate.  Afterwards the
victim may wail, `But who could have dreamt of such an idiotic-looking
move?'

Overdrawn?  But I still have checks left!

Oxygen is a very toxic gas and an extreme fire hazard.  It is fatal in
concentrations of as little as 0.000001 p.p.m.  Humans exposed to the
oxygen concentrations die within a few minutes.  Symptoms resemble very
much those of cyanide poisoning (blue face, etc.).  In higher
concentrations, e.g. 20
