Is anyone on HN using Julia professionally?
- idunning 11y ago
  Not sure they are on HN, but I know a few companies at least are using the JuliaOpt[1]/ JuMP[2] stack. [1]: http://juliaopt.org http://juliaopt.org [2]: https://github.com/JuliaOpt/JuMP.jl https://github.com/JuliaOpt/JuMP.jl

  Yes, I've used it for a number of academic research problems in biophysics. Our first manuscript that used it is in review right now. To get "real work" done, I stuck with the 0.3 line. I've found it to be quite stable. Master is quite lively but should be settling down soon, at which point I'll migrate.

  I used it professionally from 2012 - 2014, and I know of about a half a dozen companies either developing things in it or supporting it as part of saas offerings. Not that many, but each group that I know of made the switch after extensive reviews of other language options, and they've all had positive experiences so far.

If anyone has any questions about this post or the conference, fire away! Last year's first conference was a big success in my opinion. Videos are available at http://juliacon.org/2014/ http://juliacon.org/2014/, although the speakers weren't mic'ed so the sound isn't so great - we'll be fixing that this year.

  This looks fantastic! Are there any plans for a European conference?
  - one-more-minute 11y ago
    There's definitely some interest in holding a conference from the community over here – we'll probably have a go at gauging general interest and forming more concrete plans soon.

      That would be great !
  - idunning 11y ago
    Not definite plans, but serious thought is being given to having it in Europe next year if all the necessary bits can come together.

Is anyone talking about the future of the module system?
- idunning 11y ago
  No, I don't think so. I don't think there is much that is going to change with modules in the future, or at least I'm unaware of any open issues about it. What did you have in mind? The hackathon on Wednesday will be a particularly good time to bounce around your ideas, and is free to attend.
  - transfire 11y ago
    Because the current system (http://julia.readthedocs.org/en/latest/manual/modules/ http://julia.readthedocs.org/en/latest/manual/modules/) is just sad. It's the one thing that has kept me from fully embracing Julia. I would love to go if I were any where in the neighborhood. But alas I'm over a thousand miles away.
    - idunning 11y ago
      Ouch, "just sad"... would be interested to hear more! Even if you can't attend, anything you could write up as either a blog post, a Github issue, anything, would be helpful for getting some discussions going around it at the conference I'm sure.

      Some people I've talked to have complained that modules aren't objects, and that throwing away the coupling of types and reuse files is "abandoning 30 years of learning" and that "I don't trust myself to be disciplined" I think that these arguments are not strong! But what would be useful would be some detailed critical thinking on the topic. My take is that thinking about where you put multiple dispatch parameterized type matched code components is actually a real challenge. The module structure chosen for a library requires "artful" approaches. Perhaps a good workshop on the topic would yield a guide or an approach to making these decisions? Perhaps a labeling system could be evolved to provide metadata for modules better enabling reuse and promoting discover-ability ? Perhaps static analysis of a code base might be provided that gives recommendations (and assistance) for creating good decompositions and associations?
