comment Can't get DynamicModule[{..},..EventHandler[] ] working
Sorry for being a pain, but I still haven't learned how to format the code. Much of the time I come here using my iPhone which has many features in stack exchange missing. Sometime when I am at home, I will try to contact one of you on chat and learn some stuff. Want my email address?

comment When to make (file.nb) instead of (file.cdf)?
there is more to it than that. WRI could have made it so you can't use the Option Inspector to modify a CDF file. They could have made it so you can't use Drawing Tools in a CDF file. It turns out you can use Mathematica to do these things, but you can't know that from looking at the file with a text editor. I found out that I can do those things because I tried and they worked. The problem is that there are a few hundred other features that may or may not work.

comment Does Mathematica have advanced indexing?
I like the UnitStep, ReplacePart solutions a lot. Some of the other solutions are very complicated and sure to turn off people who are new to Mathematica. .... I think I finally figured out how and when to 'Add Comment' in this forum :)

comment How does Interpolation really work?
I understand cubic spline interpolation has a few different varieties depending what the derivative does at the end points. I thought InterpolationOrder->3 used a cubic spline interpolation. Is a cubic spline interpolation a specific case of a B-Spline?

comment Expression evaluation inside of FindRoot inside a Compiled Function
In that case you still might be able to improve performance if your compiled code includes a root-finding method built from scratch. It looks like you are doing root finding in 1D. If you know you can start with two points where the function changes sign Brent's method is a great choice. I could provide a Mma implementation of Brent's method. If you can't use Brent's method, another method such as Newton's method or secant method might work well. They are both easy to implement. You may also need to roll your own version of other function that can't be compiled.

comment Quality of random numbers
To learn about issues with the legacy Random numbers check MathGroup. Search for "Andrzej Kozlowski Random" and I think you will see those issues explained and discussed.
