comment Visualsinig the system of linear equation using r program
Although we cannot help you here, I will mention that probably nobody else will help you either unless you apply more of your own effort to your problems first. Surely how to produce a 3-d contour plot must be listed in the R documentation.

comment Can I model the general political landscape with mathematica?
If you don't know where to start thinking about this I would suggest browsing the site until you see something similar or related to part of what you envision doing. To be honest, for sales advice, I would recommend you approach WRI directly.

comment Can I model the general political landscape with mathematica?
Mathematica is not really suitable for making a website. You can do it in various ways, but I wouldn't choose this path myself. For back-end processing, maybe, in which case you will need a WebMathematica licence. The Wolfram|Alpha API charges depend on what you are using W|A for, and maybe for a website it will require a special contract with WRI to use their service in such a way. Can you be more specific about your needs in terms of the analysis and processing of the data than just "political modelling"? WRI do offer trials if that will help. This forum is totally unoffical, by the way.

comment Compilation of Total with compensated summation
Very interesting. I must admit I'm surprised that Total doesn't use compensated summation by default, given that it is an RTL call from the VM, and that it is so much slower than the straightforward implementation.

comment Unix 2 way communication while running M on Windows
I really don't understand your use case, sorry. What do Linux shell commands have to do with Mathematica? And have you considered just using Cygwin?

comment Protocol - Is it OK to write a long Comment as an Answer?
I would not suggest doing this on StackOverflow, because there is no provision for this in the formal StackExchange rules. But each community makes its own informal rules, and here it seems to be an accepted practice. So go ahead, as I highly doubt that anyone will complain about it. (And nor should they, in my opinion.)

Has nothing to do with the question.

Use a TVS diode.

comment How to sort my list? Help
Question is both ill-defined and too localized, and OP does not respond sensibly to requests for clarification.

comment import of a opj file (Origin)
I don't know, but I wouldn't have high hopes for it. Origin's file format seems not to be publicly documented, and there are many different and incompatible versions of it.

comment How can a high-voltage transistor be in such small packaging?
Considering that the mentioned standard is fairly costly, I believe it would be very helpful if you would quote from it the actual recommended minimum spacings as they apply to this transistor.

comment Different solutions for seemingly same Integral
@m_goldberg even if the question contains some mistakes, it also contains enough that is correct and clear to tell that it seems highly likely to be a bug (or maybe two bugs). So, I vote to keep it open.
