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?'

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 |

, the toxic effect is somewhat delayed and it
takes about 2.5 billion inhalations before death takes place. The reason
for the delay is the difference in the mechanism of the toxic effect of
oxygen in 20% concentration. It apparently contributes to a complex
process called aging, of which very little is known, except that it is
always fatal.
However, the main disadvantage of the 20% oxygen concentration is in the
fact it is habit forming. The first inhalation (occurring at birth) is
sufficient to make oxygen addiction permanent. After that, any
considerable decrease in the daily oxygen doses results in death with
symptoms resembling those of cyanide poisoning.
Oxygen is an extreme fire hazard. All of the fires that were reported in
the continental U.S. for the period of the past 25 years were found to be
due to the presence of this gas in the atmosphere surrounding the buildings
in question.
Oxygen is especially dangerous because it is odorless, colorless and
tasteless, so that its presence can not be readily detected until it is
too late.
