Re: [julia-users] Define `similar` function for a custom array

The idea of Ngram is that it is a view of N string of length k without using k times as much memory. I would like to preform operation the set of Ngram string, let's say unique(). In those cases I expect it to be treat as 1 dimension Array of String. I am making some progress with similar defin

If all you want to do is run Julia rather than build it (and the soon-to-be-C++11 libraries that it depends on), then as Peter said the best option is to use the generic Linux binaries. We just had to build GCC ourselves on the centos 5 buildbot VM we use for those, because the devtoolset does

Re: [julia-users] movingpastasquishedcaseconvention?

The general philosophy is that for user code, having underscores in names is fine, especially when the name refers to a composite thing. In Base Julia, we consider long names with underscores to be a library design smell that suggests that we're exposing something that's not sufficiently atomic. Th

Re: [julia-users] movingpastasquishedcaseconvention?

It seems such a small thing, but optional squished case bugs me. In fact, it is the one blemish on Julia that bugs me most. (Of course, that's pretty high praise for a language if the thing you like least about it is a naming convention.) Squished case

Re: [julia-users] movingpastasquishedcaseconvention?

An underscore is basically the only option here, seeing basically every other operator imaginable is taken. Still, I'm personally happy with the current convention of underscore_case alongside squished case where it doesn't hurt readability. I agree that things like `searchsortedlast` could proba

I don't see how it's magical. The function joinpath(path1,path2) gives the path of path2 relative to path1 – that's what it means. When path2 is absolute, path1 doesn't matter to answer that question. On Thu, Feb 5, 2015 at 2:06 PM, Milan Bouchet-Valat wrote: > Le jeudi 05 février 2015 à 13:55 -

You don't need a cluster manager to use MPI with Julia. You can start the Julia processes in the MPI-usual way via "aprun julia myproc". In the Julia code, you can then use MPI to determine the workers' rank etc. I have written a semi-usable set of communication primitives that work in this env
