comment Is there a way to recreate the typical Red/Blue-Postereffect using Mathematica?
I think you got the colors reversed for the text & bg... great answer nevertheless! Now if only there was a way to fix that hatch from bleeding into the bg... :)

comment Symbolic solution(s) to generalized Heat equation
@chris One huge criticism I have with the Mathematica community is that no one wants to pick up the slack and build a package for missing functionality... everybody wants everything to come from WRI. This is not sustainable in the long run and only makes us over dependent on them. Taking this example, you think symbolic solutions to the heat equation are very important. I don't. Maybe I want a new WYSIWYG HTML and CSS editor within the Front End or maybe a useless FashionData function. We can't be blaming WRI for not aligning their business goals with an individual's personal needs can we?

comment Is there a list of Octave functions mapped to the related Mathematica one?
@Mr.Wizard I think so... teaching someone to forget a particular way of thinking is much harder and in my experience, bulk of the effort must come from their end. I think that what we've been doing so far is a good strategy — user posts short MATLAB snippet, explaining what it does and also posts their best effort Mathematica translation; someone posts an answer explaining the idiomatic way of doing things.

comment Symbolic solution(s) to generalized Heat equation
Please edit your question and title to remove the focus from WRI... what the company does or does not do is not our concern. Instead you can rephrase it to ask how you can implement this in Mathematica.

comment Is there a list of Octave functions mapped to the related Mathematica one?
@Mr.Wizard As an example for the multiple outputs comment, consider sorting: res = sort(a) does the same as res = Sort[a], but [~, ind] = sort(a) is ind = Ordering[a] despite the function being called sort. And then [res, ind] = sort(a) is {res, ind} = Through[{Sort, Ordering}[a]] or {res, ind} = {a[[#]], #} &@Ordering@a, both of which would be too advanced for someone making the transition from MATLAB to Mathematica.

comment Is there a list of Octave functions mapped to the related Mathematica one?
@Mr.Wizard Then there are cases like this where both have specialized functions, yet use different definitions. In the end, I personally feel that there is no substitute for programming idiomatically in each system and that comes only with practice and reading the documentation.

comment Is there a list of Octave functions mapped to the related Mathematica one?
@Mr.Wizard I think that once you move past the basic single input-single output functions, you'll realize that there are a lot more differences — MATLAB has a single input-many outputs functionality that would be confusing to a Mathematica programmer. One of my early questions was about mimicking this (although, my question was more academic in intent and to populate the site during the private beta). There really is no equivalent to this in Mathematica (and for good reason) and you won't be able to draw parallels without causing more confusion.

comment Is there a list of Octave functions mapped to the related Mathematica one?
@Mr.Wizard I object because I think this is futile... Having used both MATLAB and Mathematica extensively, I'll second Szabolcs in saying that the two are sufficiently different in feel and functionality that compiling such a list would 1) mostly consist of trivial mappings like cos -> Cos 2) some more like ones, eye, etc. which might not be idiomatic in Mathematica. I think this will only encourage horrible programming practices in Mathematica. Also, why not Python + Mathematica, Java + Mathematica, and so on? I would probably suggest closing this question...

comment Why is SparseArray and InterpolationFunction always grayed out?
Actually, no. The functionality works fine. It just appears that it is not applied correctly to some functions.
