Re: [julia-users] what is "type piracy"?

As far as I know "type piracy" is not a widespread term in CS, but has popped up in the Julia community. Basically it refers to violations of the Julia guideline that a package shouldn't define methods of functions it doesn't own on types it doesn't own. For example, if package A exports a

I generally have pretty granular `@testset`s, which can have messages attached that are printed on failure. That way I still get a description of what failed. I think the lack of indentation for nested testsets is a regression that hit 0.5 (BaseTestNext on 0.4 indents nested testsets), and

[julia-users] RFC: Colored output API

I just filed an issue [1] that currently the print_with_color() doesn't seem to use the correct colors on my system. While checking it out, I was thinking that print_with_color might fit in nicely with Color.jl. We could pull print_with_color out of Base and add all the color terminal codes to

[julia-users] `ccall: could not find function jl_uv_dlopen` with 0.3.0-rc1

jl_uv_dlopen was added 2 weeks ago and is now used by BinDeps, so older Julia installs are breaking. Installing 0.3.0-rc4 fixes the issue. Just in case anyone else runs into the issue. peace, s

Re: [julia-users] JuliaCon Opening Session Videos Posted!

Thanks for all the hard work on these! The videos so far have come out awesome and the presenters are really easy to understand. Good capture at the event, good post work, and good projection by the presenters. The JuliaCon organizers put a HUGE amount of work into making a great conference, so

Re: [julia-users] module/function/type scope confusion

The Modules documentation [1] was recently updated with a nice table that's helpful in understanding what the various using and import statements actually do. One tricky bit is that there's a difference between bringing a name into scope and making it available for method extension. Specifically

Re: [julia-users] OptionTypes.jl

This is really great stuff. I think that figuring this out and incorporating it into idiomatic Julia code would be a really great step forward in writing code that's fast AND safe. I really liked your thoughts during JuliaCon regarding the difference between Epistemological missingness(Absence of

Re: [julia-users] Re: audio- How to play mp3 or ogg file?

AudioIO should handle any sound files that libsndfile can handle, which includes ogg but not MP3. I've considered maybe adding MP3 support using the LAME library, but in general MP3 brings along with it sufficient patent issues that I'd rather not deal with. peace, s On Sun, Jul 27, 2014 at

[julia-users] ccall not finding library installed with Homebrew.jl

Now that Homebrew.jl has support for many more packages, I'm trying to get AudioIO up to speed so portaudio and libsndfile can get installed more automatically. I'm getting Homebrew.jl to install the libraries using BinDeps, but it looks like julia isn't finding libsndfile.dylib #get the latest

Re: [julia-users] ccall not finding library installed with Homebrew.jl

Awesome, thanks Elliot! I didn't realize how to connect the library pulled in by BinDeps and ccall. peace, s On Sun, Jul 27, 2014 at 1:54 PM, Elliot Saba staticfl...@gmail.com wrote: Just to make this a little more clear, I've submitted a PR here https://github.com/ssfrr/AudioIO.jl/pull/18

[julia-users] Allocation differences in while and for loops, and from @time and @allocated

Dear big Julia meta-brain, I'm seeing some strange allocation behavior that I don't understand, so I built a minimal example that seems to be doing the same things. Here's the sample: https://gist.github.com/ssfrr/b4885e3fc10ea3f2ab9d 1. I'm getting different allocation numbers when I use

[julia-users] Re: Allocation differences in while and for loops, and from @time and @allocated

Also, to make sure that it's not some MathConst-related thing I changed `2pi` to `2.0f0` in the loop and saw no difference. peace, s On Sat, Jun 28, 2014 at 12:50 PM, Spencer Russell s...@mit.edu wrote: Dear big Julia meta-brain, I'm seeing some strange allocation behavior that I don't

Re: [julia-users] Re: Allocation differences in while and for loops, and from @time and @allocated

Thanks for the pointer to that thread. After reading it I did an even simpler example and found that in general, @time reports a different amount when called from the global context: https://github.com/JuliaLang/julia/issues/7450 peace, s On Sat, Jun 28, 2014 at 1:13 PM, Ivar Nesje

Re: [julia-users] Re: Performance of accessing object data

. With the change above, there isn't really a point to calling gc() at all, since only with_alloc allocates. Simon On Wednesday, June 25, 2014 3:24:38 PM UTC-4, Spencer Russell wrote: Mystery solved.
