And the moon on a stick :-) Not sure many "technical" programmers would take c as the desert island programing language. Sound interesting though if it can make hadoop easier to use id take that as win I dont think its going to replace fortran as a HPC language.

C as desert island programming language but making all indexing 1-based: "the first element of any integer-indexed object is found at index 1, not index 0, and the last element is found at index n rather than n-1, when the string has a length of n." Also begin end blocks - maybe there was a pascal ninja hidden in the syntax committee room?

Matlab, Octave, Mathematica, and other mathematical programming environments use 1-based indexing, it's a well-established norm for the domain.

I'm a little worried about some of those benchmarks. They appear to have benchmarked R from a few years back against 2011 Matlab, for instance. In addition, they provide no code used for the benchmarks. That being said, this looks really interesting, and I'm gonna bookmark it for when I have time to examine it properly (after the damn phd is finally submitted).

"The source code for the various implementations can be found here:" (And then follow the links for each language...)

Pretty tied into Python/Numpy ecosystem & 3rd party libs; however, after reading that (somewhat over the top, albeit very persuasive) posting, I'm definitely going to dig a bit deeper. Really nice first impression, especially like the clean syntax and calling of c -- looks promising, thanks!

Fortran too and in HPC we all code in Fortran a lot. Look at the loop construct:

     for i = 1:t
in Fortran:

     DO I=1,T
The ability to load both C and Fortran dynamic libraries is also really really nice.

They do link to the code: https://github.com/JuliaLang/julia/tree/master/test/perf . It doesn't look like a very reliable microbenchmark - run test x 5 times - but it should provide a useful starting point if you want to run your own.

Looks very much like a python without the legacy and a touch of ruby, ipython as the default shell, better multiprocessing, better os/system access, decorators and mathematics. Nice clear documentation too.

Given how similar to python they are their main competitor is pypy, which isn't too far behind them in performance I'd suspect (absent from the benchmarks though). I was fully expecting someone to make a non-compatible fork of pypy to create a faster python-like lang/something like julia. They should quickly get some elegant small libraries like sinatra/bottle and requests (access to dbs with http interfaces as well). A robust requests+lxml library built-in would be simply amazing.
