comment Detecting patterns of black and white stones on a 2D board
I am afraid this site is for Mathematica programming related questions and answers. Your answer is unfortunately written in Java and does not seem to be related to Mathematica, therefore I'm voting to close.

comment Why does the filling on my ListPlot not reach the axis for some values?
Ordering of options in Show is documented in its help page, both in the 'Details' section as well as the 'Possible Issues'section.

comment Graphing a piecewise function with very different time scales?
@kuba As far as I can see the full functionality of ScalingFunctions does not work for Plot, and its use there leads to various stability issues (kernel crashes) and (visual) errors.Try, for instance, Plot[x^2, {x, 2, 50}, ScalingFunctions -> {"Log", "Log"}].

@kuba ScalingFunctions only works for the Chart family of plot functions.

comment Create a system of linear equations with an arbitrary number of variables
I feel the closest you could get to a vector of symbolic length would be SymbolicTensors. However, they are mostly used in vector calculus like stuff (proving identities and so) and may not be what you are looking for. Perhaps it would help if you could elaborate a bit on what you want to do with them.

Look in the help under $UserBaseDirectory Details section

comment How do I upload a graph as an adjacency list and find the betweenness centrality?
Your data format is not really clear. I guess the numbers are Edgeweigths, or are they distances? And since you seem to use records with varying length I don't really understand how they code for specific nodes. Could you also provide the code that you tried?

comment How to combine more locations (GPS coordinates inside one city) with Google map?
Version 10 will have this built-in.

comment How can I plot my rather complicated function?
You still have to provide h. If you have that, you can replace x and y in the equation with h[k] and h[k] and plot f[x,y] as f[h[k],h[k]] against k. No Table necessary.

comment RandomVariate does not evaluate a Hyperbolic Distribution
It doesn't look like the impact of the third parameter is really large at the given value. The plot of the PDF remains visually unchanged if you increase it by a factor of 1000.

comment How can I use the Rules returned by FindFit?
Evaluate is a function and it is documented. Evaluated is an option. It is not documented indeed.

comment Simplifying trig expressions containing Abs or Sqrt
Are the answers given above your expected answers or the ones Mathematica gave?

comment MathLM: how do I get it?
What do you mean by Mathematica server? There is no product by that name AFAIK.

comment MathLM: how do I get it?
You also have copies of Mathematica itself installed on those machines or only the lightweight grid application? BTW as far as I know, MathLM is a different product, and also different from gridMathematica. It looks like you're confusing things.

I don't see a delay differential equation in your input.

It did work, even with the error... +1 anyway

comment Why does Arrow not work well with Scaled coordinates in 3D?
Since we seem to have agreement that this is not the expected behaviour I added the bugs tag.
