comment Use remote kernel on debian from win8
Does this work for you? I've been using this method for a while and have no problems. I think you can change the default kernel in the menu Evaluation >> Default Kernel .

comment How to not include data value outside plot range in the plot
@Silvia I guess I'm too lazy :) But seriously, usually the data I generate is a one dimensional list contains only the y value and without the x values, so it would be inconvenient to regenerate all the x values and select out part of the data, especially I usually adjust the plotrange very often. For example, I have a list consists of 100 data points run from -1.2 to 3.1, then if I want to plot the range 2.1 to 2.9, I have to do something like dt = (3.1 - (-1.2))/(100 - 1); ListPlot[Select[Transpose[{Range[-1.2, 3.1, dt], ls}], 2.1 <= #[[1]] <= 2.9 &]].

@Silvia I did consider raster, but it requires the frontend, which is quite slow for generate many plots.

@rasher but why sometime ListPlot do drop the "baggage" if we set the vertical plot range, as linked in the question?

comment How to not include data value outside plot range in the plot
@belisarius What do you mean? I think maybe I didn't say clearly, I meant to make p[[1, 2, 1, 3, 3, 1]] only contains the data points that in the plot range I set.

@rhermans I usually drop one data point if n is odd :)

comment Why IntegerPart[x/(x/2)]=1?
Thanks! I never knew that a/b is interpreted as a*(1/b). That makes me worried a little bit about all the codes I have written. Actually I caught on this because of a strange behavior of my package, and it took me a whole morning to track down to problem to IntegerPart I used in that package.
