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

In the section "Check whether two files contain the same data", there is the claim that the awk solution is O(n). However, this is dependent on the associative array entry creation and lookup being amortised O(1). Surprisingly many utilities don't use such associative arrays but instead have O(n) behaviour for sufficiently large data. This can be caused by e.g. static hashtables or hashtables that resize by a constant amount.
If the hashtable implementation _is_ good, then the solution's linearity depends on loading all data into memory. If insufficient memory is available, sort is often a faster alternative. However, this depends on many factors.

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. :)
