I am a retired software developer. I retired at the end of 2003 and since then my computer programming activities have been for recreational purposes. I find Mathematica excellent for that.

I started using Mathematica in 1997 (Ver. 3). I am currently using Ver. 9. Although I have used Mathematica for all kinds of stuff, I use it mostly to pursue my long standing interest in Euclidean geometry, both in the classical Greek synthetic form and in the more modern analytical form.

comment Problem with clipping of tick labels
I disagree with your assessment of eldo's problem not being a bug. I find that Show, given discretized graphics, is not scaling the image properly after rotation. During rotation, the graphics look fine, but as soon as I release the mouse button, bad scaling takes place.

comment Issue in ParallelTable after evaluating another function using NDSolve and FindRoot. What is wrong with this inverse?
No, not in your post. You have funcB[t_?NumericQ, k_] := funcB[t?NumericQ, k] = Exp[NIntegrate[funcA[et, k], {et, tini, t}]]. The t?NumericQ is bad.

Try funcB[t_?NumericQ, k_] := funcB[t, k] = Exp[NIntegrate[funcA[et,k], {et, tini,t}]]

comment How can my Manipulate be aware of a local variable inside a nested Module
It is always a bad idea to have variable definition as part of the first argument to Manipulate. See my answer here. The comment thread is relevant.
