Remember the good old days when we didn't have to worry about sudo or root? We have extensions, and we liked it! Why,
I remember when OS X couldn't even burn a CD! Ah, OS 9 how we miss you.
Just kidding, OS 9 sucked (that's a joke too. Sheesh, lighten up, folks). Thanks to our new Unix overlords we Mac folk should know the difference between sudo and root and this post on Linux Box Admin explains it.
Read it, learn it, and love it (in that order).
