comment Mathematica NDSolve and 'Compile'?
for some problems they do, for some they don't. have you tried comparing them for any example? it's hard to make general statements

comment Sorting list with variable
Yes that's much better than what I was coming up with. Is it OK if I add it to the answer (with credit)?

@Margus yes that's true, constant elements will remain in the order they are.

comment Implementing OCR without using TextRecognize
@belisarius yes; perhaps he's not there because when he had the energy he didn't have time and vice versa

comment Mathematica: summing over n abstract indices
I'm only joking. You understood me perfectly well, so it is my fault if this is wrong :)

@belisarius just hope he's not looking for Schroedinger or Wilson

without an example it's hard to say, but maybe NestWhile will be useful

comment compile function and floating points
@OleksandrR. I see your point (I was just experimentally looking for a small enough number so to my shame did not even know what MachineEpsilon is supposed to be). How do you feel about x = 1. + 0.001 $MachineEpsilon;x - 1 as an example, then?

@OleksandrR. I don't understand what you're saying I'm afraid. Can you unpack this a bit? (also, any thoughts on this?)
