comment How to restore corrupted files?
I'd use a simple ASCII editor to open the file and see whether it would be possible to salvage complete cells from it and perhaps try to close unclosed (because of missing closing brackets) function code.

comment Problem with mathematica plot 3d
Don't raise the function Exp to a power rather use the constant E. Either use E^power or Exp[power].

comment Time zone Projection
Could you describe the desired projection somewhat more detailed? There are many possible projections and as it currently is, your description is insufficient to answer the question.

comment Importing binary structured C++ data file
Have you tried the third syntax format of BinaryReadList (BinaryReadList["file",{type1,type2,...}])? If so, did it work for you or did you encounter any problems?

comment Invariant curves of complex functions
Could you provide somewhat more details about what you want? By the way, is your question related to the software Mathematica or maths as in the branch of science?

comment What ratio of example per class gives best results and least overfitting?
I don't believe your question is really specific to Mathematica. Rather it is a question related to classifiers or classification algorithms and their use in general.

comment Color degrades when using Copy As Bitmap
Copying a bitmap just by ctrl-C ctrl-V seems to leave the bitmap unaltered though.

comment Color degrades when using Copy As Bitmap
On Windows Mathematica versions 8, 9 and 10 have exact the same problem.

This is probably the question OleksandrR. is referring to: my-mathematica-has-turned-orange-and-not-able-to-find-out-why

comment Creating “detached” plots
Yeah, but we mostly did DisplayFunction->Identity and DisplayFunction->$DisplayFunction.

+1 for the DisplayFunction idea.

comment How to solve the heat flow PDE for the constant source term
I'm just speculating here and have never done this myself, but couldn't you rewrite your DE so that the arrow of time points backwards?

comment Fitting Data using GeometricBrownianMotionProcess
I guess you could estimate drift by a linear fit to the data and volatility by its standard deviation.

comment Fitting Data using GeometricBrownianMotionProcess
You don't. There's absolutely no reason whatsoever for peaks and dips to match.

comment Fitting Data using GeometricBrownianMotionProcess
Did you look at EstimatedProcess? BTW note that the fitted process quite probably will generate paths differing from the original. It is a random process after all.

comment How can I evaluate untrusted Mathematica code in a sandbox?
As a follow-up to belisarius' comment: try the program sandboxie. It won't help against Quit but it will prevent your computer from being messed up by the code. Related: list-of-dangerous-functions.

comment Coloured image transformation in pointillism
If you tried something but got stuck somewhere it would be good to add that to your question.

comment How to retrieve the remaining cashflows from a FinancialBond object
@user1775372 It doesn't "go back in time" because the OP was talking about "remaining coupons", i.e., coupons that will be active in the future. If you want to calculate this from a date in the past just replace the DateList[][[;; 3]], part of the code with the date of your interest.
