Julia (programming language)http://en.wikipedia.org/wiki/Julia_(programming_language)
Julia is a high-level dynamic programming language designed to address the requirements of high-performance numerical and scientific computing while also being effective for general purpose programming. Unusual aspects of Julia's design include having a type system with parametric types in a fully dynamic programming language and adopting multiple dispatch as its core programming paradigm. It allows for parallel and distributed computing; and direct calling of C and Fortran libraries without glue code. Julia includes efficient libraries for floating point, linear algebra, random number generation, fast Fourier transforms, and regular expression matching.
Julia (programming language)http://en.wikipedia.org/wiki/Julia_(programming_language)
Julia's core is implemented in C and C++, its parser in Scheme, and the LLVM compiler framework is used for just-in-time generation of machine code for x86(-64) with work being done to get it working on ARM. The standard library is implemented in Julia itself, using Node.js's libuv library for efficient, cross-platform I/O. The most notable aspect of Julia's implementation is its speed, which is often within a factor of two relative to fully optimized C code. Development of Julia began in 2009 and an open-source version was publicized in February 2012.
