I haven't used Julia for any big projects but I routinely use it for small projects or utilities. I have used it for: 1) Obfuscating source code 2) Reading and presenting iOS provisioning profile data 3) Simple social science related simulations ported from Ruby or Python. 4) Code completion plugin for TextMate etc So no huge projects, but I found Julia to be a very nice and versatile language to work in. I find I can write code which is clearer than its corresponding Python and Ruby version and which has less bugs because type info is a bit more explicit, but without getting too much in the way as is typical with statically typed languages. I tried Haskell for some of the same projects, but I got to say Haskell takes way longer time to get proficient in. For the stuff I did I also found the way the Julia type system worked, made code reuse much easier than Haskell. E.g. with the Julia Union type it was possible to define individual function across multiple specific types. E.g. I could make a particular implementation of f apply to type A, B and C, while another particular implementation of f applies to D and E. Function g could have a specific implementation of A and E. While another implementation of g is used for B and C.
