@J.M. I wrote about FourierParameters in the pitfalls Q&A, here. I noticed you mentioned this topic as a pitfalls candidate in the chat a couple of days ago. Feel free to tell me or update the post if you have something to add.

@Pickett, thank you very much for writing it! Should you find time, please include a discussion of the discrete case as well, just to stave off people complaining that their FFT "doesn't look right".

I'm trying to understand better the scoping scheme of DynamicModule. 
DynamicModule[{x},
 {x, SymbolName[x], Dynamic@x}

 ]
> {x$$, x$20784, FE`x$$928}
I understand that there is supposed to be some kind of Module-like first step but I don't quite get how this is done.
How the Kernel knows that Global`x$$ symbol name should be x$20784?
> DynamicModule first gives unique names to local variables in expr, just like Module, then evaluates the resulting expression, and then returns a version of this wrapped in DynamicModule.
But 
  Module[{x}, x]
gives x$21513 while in DM we have x$$ first.

Q: Can a comment be accepted as an answer?

SumitIs it possible to accept a comment as an answer? I often see questions which can be answered in a comment. They mostly come from newcomers and sometimes from old members (like me) as well. For me it happens because I don't know some options or proper syntax (learning everyday). If just a small h...

Hello Mr. @Wjx ,I have an another thinking about this post.If we use FindSpanningTree to find the shortest edge connecting every vertex,So how to connect some separate components with longest total length line?As we know,there are not a maximal spanning tree.
And have you look my solution in that post?Do you think why I can't get the solution?
