Re: [julia-users] Stepping avg. How faster to compute?

There is no "fast" way of calculating average of many numbers. Though the algorithm used for generating random numbers is not exactly "perfect". There is a probability distribution function involved. If you analyze that graph, then the descriptive statistics will be approximately same for all pract

[julia-users] Re: How to resolve "WARNING: both Compose and PyPlot export "draw"; uses of it in module Main must be qualified"?

Thanks for the help. Using ' Compose.draw(img, compose(sierpinski(8), linewidth(0.1mm), fill(nothing), stroke("black"))) ' results in no plot output whatsoever. Using ' PyPlot..draw(img, compose(sierpinski(8), linewidth(0.1mm), fill(nothing), stroke("black"))) ' results in the following

You can always just ccall fork. Not portable but it should work. On Sunday, January 10, 2016, Thomas S Hatch wrote: > Thank you for the confirmation. One valid point in the Linux world is that > is daemons are being started via systemd there is little need for the old > pid fork anyway as system

[julia-users] Re: What happens when I do x[:] when x::SharedArray{Float64,1}?

I think this differs between master and release, a few of us are still not happy with similar of a SharedArray not returning a SharedArray. I wouldn't rely on anything staying unchanged here.

Re: [julia-users] trying to build Cxx, general

- Cxx.jl master - Julia with `LLVM_VER=3.7.1` - and manually patched LLVM (but this is probably only necessary on Mac) https://github.com/JuliaLang/julia/issues/14585#issuecomment-169712071 However, at this point, unless you are willing/able to debug LLVM-level issues, I don't recommend using this

[julia-users] Change DataArray/DataFrame column type

I have a dataframe which contains `NA` and float values. I would like to change the datatype of one of its columns from `Any` to `Float64`. The solution I found on the web df[:x] = float64(df[:x]) yields a deprecation warning to use `map(Float64, df[:x])` and a conversion error. The map soluti
