I've noticed: "I guess we can announce alpha support for arm in 0.4 as well." (and the other thread on Julia on ARM). Now, Android runs on x86 (already covered, then if you have that kind of device, no need to wait for ARM support), ARM, and MIPS (actually do not know of a single device that u

[julia-users] Re: Does union() imply worse performance?

I'm pretty sure yes. And it seems like a little strange thing to do.. You can use the code_native function to see the code and I did something wrong so I'm not sure I confirmed, but you could try out with and without bool (and Union). If you get lots of code then the length (longer) should be a

I've seen Julia's non-checking of integer overflows questioned (and I know the answer/performance section (and BigInt alternative, that is just slow/overkill), and recall a discussion in the forums). Just now I noticed: https://github.com/JuliaLang/julia/issues/855 [for 1.0 milestone - after

Strictly speaking, according to Stallman himself compilers do not affect the license of binary produced by a compiler. However, the the C library, that you usually incorporate, that is GPL, it would make the whole binary GPL, if it were not for the GPL exception used. I wander what would be tru
