So the other day I messaged another admin from the console using the regular old 'write' command (as I've been doing for over 10 years). To my surprise he didn't know how to respond back to me (he had to call me on the phone) and had never even known you could do that. That got me thinking that there's probably lots of things like that, and likely things I've never heard of. What sorts of things do you take for granted as a natural part of Unix that other people are surprised at?
Otherwise I reject the idea of income redistribution.
Repeat after me: Progressive taxation is not wealth redistribution.
If the government takes 1% of the income of someone making $20k a year, it has a much greater effect on the lifestyle of that person than than if you were to take 1% of the income of a person making $250k a year. To say that the 1% is "equal taxation" for both people is just plain silly.
