comment All irreducible factors of a polynomial over $F_{p[x]}$
I'm voting to close this question as off-topic because because the issue it raises is not a Mathematica issue but a mathematics one. That it is formulated in terms of Mathematica is not sufficient to make it an appropriate question for Mathematica.SE.

comment Help needed with assignment
As posed this question is not very attractive to those who could probably answer it. It asks them to do too much work for you -- work that you should have done before you posted the question. Your post would be much more attractive if you were to edit it to include: 1) a markdown formatted data set that can copied into Mathematica for use as test data; 2) a markdown formatted Mathematica expression or an image showing what you expect the final output to look like; 3) the code you have tried and and explanation of why you find it unsatisfactory.

comment How to disable dynamic update in DynamicModule when certain variable is updated
To answer your question, we would have to know how your progress bar is coupled to your other dynamic variables -- that is, we need to see your code.

comment i need generalized code for genetic algorithm(an optimization technique)?
I've written several GA implementations in the last 30 years. I can tell you that implementing chromosome modification (mutation, crossover, reversal, etc.), creating the initial population, and evolving the population are all easy because these things require only a little programming skill. What is hard is defining a good chromosome schema and a good fitness function. These last two things are hard because they require extensive domain knowledge as well as programming skill.

comment Adding a 3D point using Epilog
@SjoerdC.deVries. Yes, but the graphics primitives in the list given to the Epilog option must all be 2D.

comment How to map over the corresponding elements of matrices
Evidently, your interpretation, and not mine, was the correct one.

comment Understanding a code for exploring XML tree
As for how the recursion is built-in, definitions such as f[x_, y_] := {f[x], f[y]}, for example, are clearly recursive and, therefore, induce recursion in the Mathematica kernel when f is called with two arguments. The kernel keeps evaluating an expression it is working on until it reaches a fixed-point.

comment Understanding a code for exploring XML tree
You should not write code with a structure you do not understand. That way lies madness. You should not just read the excellent tutorial on Transforming XML, you should work with its examples in your own Mathematica notebook. Then, perhaps, you will acquire enlightenment.

comment Evaluation speed of apparently equivalent functions
I would be surprised if [x_Integer] := x were not the fastest of the examples you give, for the simple reason that it requires the least effort to determine whether the actual argument passed matches the argument pattern.

comment Discrepancy in the series expansion of $\log(z/(z-1))$ in Mathematica 5
The OP's result is not local to V5. In V10.1 Series gives the same result.

comment How can I perfect this game for Wolfram Demonstration publication?
I'm voting to close this question as off-topic because it is too localized; i.e, it applies only to the local situation and needs of its poster and answers will not benefit others.

comment Suppress attributes of all XMLElements of a XMLOBject
I'm voting to close this question as off-topic because the OP posted this question again later with more detail, thus invalidating this one.

comment Animating a Sphere to move along a 3D curve
The title says 3D curve, but the question body says 3D function (aka surface). Which do you mean?

comment NDSolve second order differential equation with boundary condition
Hint: bc2 is not bound to an equation form. You may have meant bc2 = Pa[0.009] == 1

comment Button labels in different platforms
@magma. I learned the identity of the system fonts from a Google search. And you are right, "SB" was a typo, which I have now corrected. That "SR" is Helvetica is a guess based on long experience with Helvetica.

OK, edit your question to provide the pieces. We should be able to help you write the glue code.

comment Need help with code for number theory problem
Your question reads as if you are looking for someone to do your homework for you. We don't do that. Especially as you don't provide complete specification. We are willing to help with specific coding issues expressed in Mathematica code

comment ComplexExpand does not treat everything as real number
I'm voting to close this question as off-topic because this is question results from a mathematical misconception on the part of the OP.
