[julia-users] ANN: node-julia

It's usable enough now, so it's time to announce this. node-julia https://github.com/waTeim/node-julia is a portal from node.js to Julia. It's purpose is partly to allow the node-HTTP-javascript guys access to the excellence that is Julia, and visa versa the Julia guys access to the HTTP

Re: [julia-users] More with embedding with dynamic libraries (Linux)

Oh I knew I could count on you guys. Thanks for the reply, of course my natural response is. What is RTLD_GLOBAL? Don't worry too much about that, I can probably look it up. I found a not desirable workaround by setting LD_PRELOAD to load libjulia.so first, but that causes a 2nd problem see

[julia-users] More with embedding with dynamic libraries (Linux)

Hi all, Remember this problem with dlopen and openblas https://groups.google.com/forum/#!topic/julia-users/A8HwlmldVTM? That problem was resolved by modifying how embedded Julia loads (perhaps only on OS/X).Well now there is a similar problem on Linux. Same software. The exact problem is

Re: [julia-users] How come (x, y) isn't legal syntax?

I would add that ()(1,2) works; I'm imagining that it changes the context and forces the parser to use the one legal interpretation.

Re: [julia-users] Re: self dot product of all columns in a matrix: Julia vs. Octave

I feel that x^2 must among the things that are convenient and fast; it's one of those language elements that people simply depend on. If it's inconvenient, then people are going to experience that over and over. If it's not fast enough people are going experience slowness over and over.

[julia-users] Unable to dlopen openblas and dSFMT by default when using embedded Julia

This is on OS/X I do have a workaround, but I'd like to get to the bottom of it. I don't see anywhere in the code where either of these 2 libraries are loaded explicitly --- maybe it's in loading sys.ji? My workaround can be to set an env variable, but it would be better to understand and

Re: [julia-users] Unable to dlopen openblas and dSFMT by default when using embedded Julia

In fact this does indeed just work. I did need to specify rpath, but didn't need to do anything else, this one value of rpath during the link step was enough to resolve both libjulia and libopenblas, etc. e.g. -Wl,-rpath,/usr/local/julia/lib/julia, Also. *Version 0.4.0-dev+92
