"Julia is a high-level, high-performance dynamic programming language for technical computing, with syntax that is familiar to users of other technical computing environments. It provides a sophisticated compiler, distributed parallel execution, numerical accuracy, and an extensive mathematical function library." - julialang.org
Here, we meet two members of the Julia design team - Stefan Karpinski and Jeff Bezanson - to get a casual peek inside Julia (why a new language, what makes it special, why "Julia" for the name, etc...). You can (and should!) watch Stefan and Jeff's Lang.NEXT 2012 session for more details (and more formality).
