comment Plotting iterated function system images
@AJY I've added the code defining the depth level version of ShowIFS to the response. It works fine in V9 on my mac. The package contains some other features as well. I don't know why you're having problems with it on your machine. I assume you unzipped the file, opened up the Installation.nb file and executed the commands in order - including the PrependTo command?

@AJY Were you able to get my packages to work? I'd certainly be happy to help.

Did you execute the PrependTo command in the Quick start section before the Needs command? If so, what OS and version of Mathematica are you running?

comment Mathematica vs Python - how does it compare to Python's scientific computing suite?
@halirutan While your question is a good one to ask, note that the original question as asked in the next to last paragraph specifies "other than in computer algebra". Probably, the OP is aware of sympy which is, frankly, vastly inferior to Mathematica. Sympy fails on your suggested integral, for example.

Nice - and, it deals with the colors much better than I anticipated!

comment Ghost trails with Animate?
@Kuba Neat! I never noticed a function that actually declares itself as undocumented in its name before. I'm curious - how did you avoid the problem that I had with the misbehaving invisible characters after copy/paste? It looks like you used 4 space indentation; maybe that's it? My code was inline.

Sadly, the Import code I just wrote doesn't seem to survive a copy from the comment box. Hopefully, you get the idea.

@Kuba But then, you wouldn't have the joy of writing code to extract the code. :) code=StringJoin[Cases[First[Cases[Import["http://mathematica.stackexchange.com/‌​questions/75936/ghost-trails-with-animate","XMLObject"], XMLElement["td", {_, _, "class" -> "answercell"}, ___],Infinity]],XMLElement["pre", {}, {XMLElement["code", _, {code_}]}] :> code, Infinity]]

comment Module function corrupts string?
+1 @TraceKira This code is much more idiomatic and easily readable by anyone who is familiar with Mathematica. This style of programming is also much more efficient in Mathematica, as I've tried to illustrate in my edit.

@B.Lee An accept is ample and you're welcome. Maybe Beli could bounty it, as he has 64K these days. :)

comment Graphs Plotting Discontinuous
Much faster, in fact! I actually considered that but didn't try it as I figured it would be very slow as Eigenvalues is evaluated with each and every step. Evidently, the list Root objects take longer to evaluate than Eigenvalues, which might very well be evaluated numerically in this context. Looks worth a +1!

comment Graphs Plotting Discontinuous
But now, all the plots are the same color. Worse, the standard tricks involving Evaluate, With, or the Evaluated option all bring the discontinuities back, as Chop applied to non-numeric expressions just returns the expressions. I was only able to resolve this by generating the data and using ListPlot.

comment Graphics3D not rendering Ball as a filled object
@m_goldberg Show[{DiscretizeRegion[Ball[],{{0,1},{0,1},{0,1}}],Graphics3D[Sphere[]]}] works fine for me. I really don't understand your object to the answer at all. Regardless, the assertion that it's not relevant seems patently false.

comment Graphics3D not rendering Ball as a filled object
@m_goldberg Well, you asked if it was a bug. I replied "this is a minor bug" with explanation as to why I consider it to be minor and suggested a workaround.

comment StreamPlot for Bifurcation Diagram
@Stephen I'm glad you found the code useful! It sounds like you might need to incorporate a SaveDefinitions option into your code, if you want the dynamic content to work when you open the notebook. It's hard to say for sure, though, without seeing your code.

comment Enumerating all connected graphs with 9 vertices
Should be faster if you use FindIsomorphism[g,g,All] on a Graph object. On my iPhone right now so I can't try it just now.

comment Fitting ellipse to 5 given points on the plane
@Jens My assumption is that the OP simply wants to add more points that are know to be on the same ellipse, rather than find a best fit.

comment Fitting ellipse to 5 given points on the plane
@user153012 If you'd like to plot more points in a list, say morePoints, simply add another Point primitive containing your list to the Epilog.
