You can also try Julia in your browser here: https://cloud.sagemath.com However, you have to (1) make a free account, (2) create a project, (3) open project, click on "+New", click Terminal, (4) type "julia". If you create a .jl file instead of a Terminal (at +New), you'll have proper Julia syntax highlighting and indentation; you can then run that file from the terminal...

As a general question, is Julia Studio the best way to go about setting up a workflow? Or should I go with something like a Julia plugin for Sublime Text (which I believe exists). Or are there any other tools out there that make Julia dev straightforward?
Julia's standard library includes a host of mathematical functions, in addition to the standard operators. Complex numbers are also supported, using the built-in im unit:
round(pi)
lcm(54, 392, 232) # least common multiple
sqrt(square(100))
e^(pi * im)
log(e ^ 2) + log10(100)
When you're ready, type "next" to continue

no method round(MathConst{:π},)I've been struggling with building a C++ library for astrodynamics simulations (anything involving the motion of objects in space) within my research group for the last four year. The biggest problem is that for our applications, performance-wise a lot of high-level languages just don't cut it (particularly MATLAB, which is pushed down our throat from freshman year onwards). After some deliberation (and before Python…

Not seeing a prompt. It might be because of the internal "POST http://forio.com/julia/repl/sessions 503 (Service Unavailable)" error?
Probably got "slashdotted".
Everything returns: Undefined 500 Is this broken?
There are several options, I chose the one with sudo gedit /etc/apt/sources.list and

Regarding workflow, the best option is IJulia ( https://github.com/JuliaLang/IJulia.jl ) which has nice integration with plotting and useful things like LaTeX. Vi and Emacs are well-supported, and I know the Sublime tools have gotten a lot of attention from several people.

That JPL Ephemeris library has given me an idea. I think I might try porting over the NAIF Spice [1] toolkit to Julia. It has MATLAB, IDL, C and FORTRAN ports so I think Julia would fit right in there.
