This is a cute collection of fun software bugs from Michael Tsai’s blog: Funniest Software Bugs.
I incidentally enjoyed learning about the units shell command, a useful utility to convert between units from the command line:
stefano ~$ units 586 units, 56 prefixes You have: 100 feet/s You want: km/hr * 109.728 / 0.0091134442 You have: 30 J/yr You want: erg/s * 9.5066294 / 0.10518975
(Its man page informs me that it cannot convert Celsius to Fahrenheit, since it can only handle multiplicative scale changes: boo!). And what the heck is a fathom?
