in reply to Bit operations for beginners

It's a good start at a useful topic for those who haven't gone through a basic Boolean algebra course (such as electrical logic or an optional part of high school algebra).

I would even recommend this move into Tutorials, if you could tighten up the topic a little more and pay a little more attention to grammar, readability and markup. I'd probably recommend you refer to ~ as the bitwise 'inverse' operator instead of the bitwise 'not' operator, to reduce a little confusion.

The parts about using bitwise operators on strings or characters may be more clear if pulled out into a separate section: bitwise strings is just like a loop, performing bitwise operations on each character position in the pair of strings.

Also, instead of briefly explaining logical operators (! not && and || or), and the use of DeMorgan's Theorem, just leave a caveat that these aren't bitwise operators-- plenty of material for a follow-up tutorial.
