[julia-users] Re: Cxx.jl: Creating a templated class

Is this in any way related to https://github.com/Keno/Cxx.jl/issues/212 ? Any pointer what this means? ERROR: LoadError: Creating LLVM constants for type `T` not implemented yet On Monday, July 4, 2016 at 10:09:34 PM UTC-7, Jan Strube wrote: > > What's the right way to create a templated class

Re: [julia-users] list kw args

Thanks, I've found function: kwarg_decl(sig::ANY, kwtype::DataType) in develop version (not stable version 0.4.6) But I cannot understand (also following code flow) what is kwtype parameter and how kwarg_decl can be called. And finally, can this code run on current stable version? Many

[julia-users] Pkg "threadsafe" or interprocess mutex package

Hi, I have a script that is using some packages. The script is set up such that if the package it is trying to use is not installed, it will do a ``Pkg.add`` to add the package before ``using`` it. This script is triggered by a third process, and it might be triggered multiple times

[julia-users] Re: How to fix writemime deprecation?

Correct. This still needs a doc update (I added #16763 to the v0.5.x milestone). The two-argument form `show(io, x)` should produce a concise, single line description that formats reasonably into any unknown context. The three-argument mime-format aware version `show(io, mime, x)` can be

Re: [julia-users] R code to Julia Performance issues with pmap

This is not entirely true in R: Details: ‘proc.time’ returns five elements for backwards compatibility, but its ‘print’ method prints a named vector of length 3. The first two entries are the total user and system CPU times of the current R process and any child processes on

Re: [julia-users] R code to Julia Performance issues with pmap

I am not seeing your speed-up in R? elapsed is less time, but user significantly more, and it is the sum that counts. When executing in parallel the language needs to copy the data to the workers. If the matrices are large, that takes longer than the speedup of the parallel execution. See what

Re: [julia-users] list kw args

The implementation is not trivial to follow, but have a look at `kwarg_decl` in `base/methodshow.jl`. This might be a reasonable thing to have as a helper function, if you want to open a GitHub issue to discuss. (Be warned: you will pay a severe performance penalty if you try to use reflection

Yes, but I am not using BLAS or FFT transforms so it si a bit surprising that I am not getting any speed improvements On Wednesday, July 6, 2016 at 2:17:49 AM UTC+2, Stefan Karpinski wrote: > > Similar question and answer: >

Re: [julia-users] Re: Master list of constants

While we're at it: since all constants in that list are represented by their symbols, with the names serving as aliases, would it be a good idea to define Catalan's constant using the G symbol? If that's too common a character which we
