Anyone who considers arithmetical methods of producing random numbers is, of course, in a state of sin.

Thanks for another excellent post!
Which shell are you using? In bash 3.2.48, the builtin read takes a lowercase -n.
I have the following in my .bashrc:
alias timer='(stty -echo; time read -n 1; stty echo) 2>&1 \
| grep real | sed "s/real/Elapsed time:/"'
Alternatively, one could use:
command time -f "Elapsed time: %es" bash -c "read -n 1"
Not sure why, but stty doesn't seem confined to the sub-shell; ergo calling it the second time.

I love to read science books. They make my day and I get ideas for awesome blog posts, such as Busy Beaver, On Functors, Recursive Regular Expressions and many others.
Take a look at my Amazon wish list, if you're curious about what I have planned reading next, and want to surprise me. :)
