comment Issuing user-defined messages takes a long time (Message is slow)
I have very similar timings under V8 and V10 (did not check V9 now) under Linux

comment Potential pollution of Global` context in fresh kernel
Nevermind my earlier comment, I get {"list", "msgs", "rhs", "z"} under Linux.

comment Transparency rendering problems in Mathematica 10 (Mac)
I can reproduce the dots you see under Linux. Also, I think that @Thomas is correct. Try this: Contours -> {.9}, ContourShading -> None, ContourStyle -> {{Red,Thickness[0.1]}}

comment Mathematica Destructuring
I just stumbled over this and I have to say I really like it! Using this with the shorthand notation is especially neat!

comment Is there a way to solve the linear equation, Ax=b, in which A is a “non-constant” sparse matrix that depends on x?
@murray I'm a bit confused by your comment... How is it a linear equation if A depends on x at all?

Very neat! Never thought about this one!

revised Copy a variable to a specific kernel in Mathematica
Shortened question to be more focused on what the OP is really asking.

comment Copy a variable to a specific kernel in Mathematica
I took the liberty to delete the second half of the question, which I think is not really relevant for what you are trying to achieve (edit still has to be reviewed by the mods). Hope that is ok for you, otherwise please revert it.

comment Copy a variable to a specific kernel in Mathematica
@TheQuantumPhysicist So in this case I would suggest that you edit your question to make it clear what you are really looking for, i.e. a way to set a variable on specific kernels. It would also be worth a look if there are any duplicates out there. I did a quick search but didn't find anything appropriate.

I can confirm the exact same behaviour on Linux Mint Debian with both Mathematica 8 and 9.

comment Copy a variable to a specific kernel in Mathematica
Then you can still do what I suggested above, just with a subset of Kernels[]

comment Copy a variable to a specific kernel in Mathematica
I can't answer your question and honestly I'm not completely sure what you are trying to do, but for the second snippet of code you would use something along the lines of With[{var2=var2},ParallelEvaluate[var=var2]]. Also note that mapping over Kernels[] is not necessary as by default the command is evaluated on all available kernels.

Nice, I like this way much better :)

Ok, we will see what the OP says anyways.

I am guessing this is math homework and should be migrated, don't you think so?

comment Make Sinc'[0] return 0 instead of Indeterminate
I of course agree that you need to take the limit but the same reasoning could be applied to Sinc alone. So I agree with @Rojo above that the reason to have a Sinc function should be that you don't have to evaluate Limit[Sin[x]/x,x->0] every time. It would be nice if the same was true for Sinc'.

comment Double integral with variable in the limits
@AlexeiBoulbitch Can you elaborate on your comment a bit? I would be interested what you mean with quasi analtytical. Also, how do you know it's not dimensionless?
