Probably because a hacker news comment isn't the best place for a feature request about using a proprietary library and comparing to a commercial distribution of a different language. By the way, Julia partners with Intel as well, but

See https://github.com/JuliaLang/julia/issues/18374#issuecomment... . Open-source Julia builds also need to support non-Intel processors and architectures, and operating systems where MKL isn't available.

The wonderful thing about OBS is you can branch a package, make modifications to your personal version, and add that new repo as a source for zypper to pull from, incredibly easily. PPA's and Launchpad are orders of magnitude more comp

Most Julia users run code more often in an interactive REPL session rather than as a script to do a single thing. The precompiled code loading is now on by default on Windows in Julia 0.5 since the backtrace issue was fixed, but there'

All over, but with decent sized groups in NYC and London. Hard to quantify exactly, but see the sponsors list of the juliacon events for some examples.

> do you know of any teams or companies using Julia in anger in a non-scientific setting, with programmers from a non-scientific background? It's catching on among early-adopters in finance. What do you consider that?

It's an interesting sight, seeing remnants of tourism and an ecosystem that has been decaying for decades. Route 86 by the Salton Sea is the only place I've ever set cruise control to triple digits (mph) and still been passed by m

Modern Fortran gets a bad rap, it's suprisingly good at what it does. I wish there were more than one production quality open-source compiler though.

> this requires timholy's fast lambda package Not on nightly. That's fixed now. The technical concerns here about startup time etc are fixable, we'll get to them.

No summer of code students have had projects that involved work primarily on the core language since 2013. Not that many posts happen on julia-dev because most of the development communication happens on github.

And the Fortran-convention BLAS API is quite a bit more widely used than the CBLAS API. idamax in the Fortran API, and pivot vectors in LAPACK factorizations, return 1-based indices.

I find I don't pass individual array indices back and forth between C and Julia as often as I would in Python or Matlab, since I don't need as much compiled interface glue. You can do iteration and the like entirely on the Julia s

Entirely handled by the underlying BLAS library, OpenBLAS and MKL have this feature but few if any other libraries do. I believe FFTW has something similar, but scipy doesn't use FFTW.

Just don't try to have both a zero sized array and a flexible array in the same struct. g++ 5 or earlier will compile that, but g++ 6 will not: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=69550

Just tried loading a 6MB json log, and it froze Atom horribly. On a nice laptop, less than 6 months old. Not sold yet. Waiting for VS Code to implement tabs then will give that a more serious look.

You have an underinformed and incorrect understanding of what happened there. Leave it at that.

A better compiler is a good thing, as long as its performance model can stay reasonably transparent. https://github.com/JuliaLang/julia/issues/8974

You have to some extent switched to a different language when you're using Cython. Do you teach Cython to newcomers when you're introducing them to Python? If no, why not? Performance and parallelism shouldn't require hurdles

Sure. But self-hosting pacman makes it literally impossible to do correctly. Updating cygwin itself should be done by an outside-of-cygwin solution to invoke setup.exe, just write a little powershell provisioning script or something.
