I think I understand how a flip-flop works thanks to this tutorial, but the example there is contrived just for teaching. Can anyone give an example of how you have actually used or would use a flip-flop?
Edit: I'm looking for a real-world application, not just another demonstration. What problems can this tool solve?

I'm dismayed. Ok, so this was probably the most fun perl bug I've ever found. Even today I'm learning new stuff about perl. Essentially, the flip-flop operator .. which returns false until the left-hand-side returns true, and then true until the right-hand-side returns false keep global state (or that is what I assume.)
My question is c...
So, I believe this has something to do with the difference between arrays and lists, but I don't understand what's going on here. Can anyone explain how and why Perl treats an expression like (1..4) differently than (1, 2, 3, 4) and @{[1..4]}?

I know this isn't really a programming question, but it is definitely computer related and someone might know this.
How do you construct a SR flip-flop with a D flip-flop and other logic gates?
I understand that ultimately, what you want is logic gates (with S and R as inputs) connecting in to the D input of the D flip-flop, but I am...
