The first link (#Rational) explains the issue:

In Africa, people regularly pay a "prophet" 1/3 of their monthly salary
for a bottle of gasoline juice. The gasoline juice cures cancer, brings
dead children back to life etc., maybe programmers drink it to write
software that can be used to take snapshots of file systems that don't
support snapshots. However, to my limited atheist's knowledge gasoline
can cause cancer and can kill children, I doubt that it cures cancer,
brings dead children back to life or does other faith healing. In other
words, is the source code of the backup software available that performs
miracles?
