comment Undeclared Identifier error in Compile
I am sorry, but without those definitions, the issue is not reproducible and so the question is not answerable. Therefore I have to vote to close your question as it currently is. If it is closed before you are able to update it, please cast a vote to re-open after you have done so, and I'm sure other users will follow suit.

comment Real time solution of a DE with changing parameters
You need to give the system of equations, the range of values that the initial conditions can take, and how quickly you need a result after changing any of the values to be in with a chance of getting an answer to your question. Otherwise, your answer will just be: use Manipulate and ParametricNDSolve.

comment JacobiCN inaccuracy
@Guesswhoitis. I do not see this on version 7.0.1 on Windows (nor version 5.2, or any other version for that matter). The axis labels look like they come from Linux. Unless we can find someone to reproduce it and label it as a bug, I suggest we close this as irreproducible.

comment Global` context not empty at startup in v10.2.0
@ilian that's possible. If the second bug doesn't get fixed before the next release, then I'd support that. But for the time being I don't think there's very much to be gained, from our perspective as users, in having separate questions so long as the bugs aren't independently observable. (After all, this is not a formal bug tracker, but a way for users to know whether unexpected behavior is due to a bug or not.) If you have a test case for the second bug that differentiates it from the first in a way that a user could feasibly observe, by all means, please post that as a separate question.

If you have the gradient, then what's the question?

comment Global` context not empty at startup in v10.2.0
What an oddity. Good job in narrowing this down. I suppose it also suggests that a huge number of symbols are being created all the time in obscure contexts, most of them having no usefully persistent definitions and never to be used again. I wonder what impact all of this has on performance?

comment Global` context not empty at startup in v10.2.0
I just want to respond to the closure and justify my casting of a re-open vote. This is the same type of bug as in the other question, but it is not the same bug. The last one was fixed; this one isn't, and it isn't a regression either, because the symbols are different, as are the circumstances under which the leak appears.

comment How to implement the sample-point process like the built-ins of Mathematica?
Well, the PostScript renderer was amazingly fast, and FullGraphics and AbsoluteOptions actually worked on this type of graphics output. So I miss it for those reasons at least. It's nice to see it brought back (for a brief outing, anyway) nearly a decade later.

revised FullSimplify wrongly reduces expression to zero
bug does not exist in 8.0.4, so must have been introduced in 9.0 (but not sure which version)

comment How to simulate a homogeneous nucleation?
For anyone who actually does not know (or has forgotten) about nucleation, this very nice slide deck by Leonid Zhigilei of the University of Virginia will be helpful. What the OP is seemingly driving at is how to make the rate of growth of the nuclei dependent on their radius and local environment.

comment How to simulate a homogeneous nucleation?
Other commenters have been trying to prompt you, but I think you misunderstand. We all know what homogeneous and heterogeneous nucleation are. The point that people are driving at is: how is your question any different than, "write a simulation of homogeneous nucleation for me"? You seem to have done very little or no work towards this yourself, which makes people disinclined to answer. You do not even clearly define what physical situation the simulation is intended to model.

comment Probability Quesiton Help
Sorry, wrong site. This one is for users of the technical computing software Wolfram Mathematica. You probably intended to ask this at math.SE instead. Your question will be migrated automatically if you don't choose to move it yourself before that.

comment Global` context not empty at startup in v10.2.0
@Szabolcs PLI stands for "Programmable Linguistic Interface". It is in the Semantic` context, which contains things like parsers for various inputs into Dataset objects, although it is not clear to me exactly what it does here or how it works (it seems to be mostly cloud-related). See symbols under Semantic`PLIDump` .

comment Speeding up the built-in Rudin-Shapiro and Thue-Morse sequence functions
I just wanted to point out that the compiler builtins are very fast and don't depend on the existence of the POPCNT instruction, so it is not necessary to use the lookup table. My home computer, for example, doesn't have it. I am actually not sure how the CRTs do it--maybe they indeed use a LUT, but it is surprisingly fast if so. If a HammingWeight function were implemented, it would be a very good building block for all sorts of other functions, of which this seems a good example. Better if it would not be necessary to use IntegerDigits, but this is of course a constraint of LibraryLink.

comment Saving numerical values to a *.dat file
Your question has the same problem as this one: DAT is a file extension, not a file format. One of the most common file formats with DAT extension used to be raw MPEG2 stream. I presume you don't want that. If you have specific requirements of the file format, you should specify it more directly.

comment Undeclared Identifier error in Compile
I upvoted your question because I think this probably should not happen. However, it is not really answerable without the definitions of PointIsWithinCircleWidth and PointIsOnCircleWidth given, so please include those in the question as well. Welcome to the site, by the way. It is a rarer thing than you would think for a brand-new user to post a (almost) fully formed and properly formatted question, and it is appreciated.
