[julia-users] Re: so many plotting packages

i wasn't looking for recommendations. am happily using gadfly. started out with pyplot three years ago. rather, i just think the julia community would benefit by collecting all these packages in one place. since tbreloff appears to want to keep an iron grip

[julia-users] so many plotting packages

would be nice to have an organization to contain all of these. as @StefanKarpinski pointed out (i forget where exactly), it would help to encourage developers to work together. it would also help new users of julia figure out which package they want to use

[julia-users] run() yields in @async, why?

spawn() and readandwrite() are documented as being variants of run() which do not block the command line. yet in an @async, run() seems to yield to other tasks. to wit: # bar prints first because it's the first task julia> @sync begin @async println("bar") @async (run(`sleep 10`);print

Re: [julia-users] calling libraries of c++ or fortran90 code in Julia

turns out the problem wasn't name mangling, but rather that the C++ function was defined to be static. hence readelf labelling it as "local". removing "static" and recompiling fixed the ccall errors.

there might be a way to fix this, but since i'm in a hurry, i decided to just modify the C++ so as to avoid mangling. thanks for the help.
