Although I'm quite familiar with Mathematica, I always try to keep an open mind and don't use it as golden hammer. I'm particularly good at things that are fun, for instance

comment Can i change the default search paths?
How about writing up your own answer? So that others that may have the same problem find help.

comment Can i change the default search paths?
Yes it can. Simply use AppendTo[$Path, "yourpath/here"] although I don't whether all network drives are accessible.

comment Can Mathematica solve Plateau's problem (finding a minimal surface with specified boundary)?
@Narasimham This was really only an example. I'm interested what one could do in the general case with not too evil initial curves. If you can share knowledge about this, I would be happy to hear it.

comment Simple Choice-Dialog like the auto-completion popup
@Kuba I tried to re-implement auto-completion for the FE. So the goal is that when you start typing, a pop-up appears with suggestions, just like it does with the normal auto-completion. This is why the at cursor position would be very helpful and why the pop-up should grab some of the keyboards attention.

comment Can Mathematica solve Plateau's problem (finding a minimal surface with specified boundary)?
In your answer you have an initial guess for the surface which is the parametric plot. When I understand the question correctly, then the starting point is only a curve. Do you know a solution when we have for instance this curve, let's assume not even analytically but as coordinate list. Do you have an idea for this? Additionally, it would be awesome if you could provide some links to algorithms/literature.

comment Can't comment strings with '*)' inside it
If the closing *) is, like in Murta's case, part of a working Mathematica expression, I wouldn't use this because when you un-comment the region again, you have to go through your entire expression and remove the `. Using (*(*` at the beginning is easier IMO here.

Very nice question. Thanks for taking the time ask it and write this up so carefully. +1

comment How to reduce a quartic form to a quadratic form with equal roots
@E.O. That's better, because the guys over there should know the theoretical background of your problem. I have another question: You write we can assume that the variables only take 0 or 1 as value. Is it important that the polynomial is positive everywhere or is it enough when it is positive when the variables have 0/1 values?

comment Beginner CUDA: two dimensional blocks and two dimensional threads?
The main reason why I don't use it anymore is that it is a pain to keep things working throughout all operating systems but more important is, that my colleagues don't have the hardware I have and it is very likely I have to rewrite code if I want to share the CUDA stuff.

Please edit your example so that it is a working piece of code.

comment How to reduce a quartic form to a quadratic form with equal roots
I don't understand your example x y - z w - 1 because in the first sentence, you say that you have a polynomial of the form P=(...)^2 but your example is not of that form. Furthermore, if you have P=f*f doesn't that imply that f has the same roots as P and it is what you want? Except that it might miss the property of being positive. This all looks like it is a question for Mathematics.
