Thou shalt not have any other programming languages/OS before Java/Linux
Thou shalt not make unto thee any golden image, since there is no such thing
Thou shalt not use the name of the root in vain
Remember the backup day, to keep it holy
Honour thy sysadmin and warez supplier
Thou shalt not kill -9
Thou shalt not commit cyber-adultry
Thou shalt not steal media online
Thou shalt not play with false negatives when tuning your spam filter
Thou shalt not covet every new CPU model and GFX card
