The document summarizes JuliaCon, a conference about the Julia programming language, held in Chicago on June 26-27, 2014. It provides details of the conference schedule and sessions, which covered topics like scientific applications, optimization, statistics, and graphics in Julia. It also describes some of the presentations, including one on the design and implementation of the Julia debugger by Keno Fischer. The author shares their experience of attending the small, 70-person conference and plans to hold local Julia user group meetings in Seoul to share knowledge gained from the event.

- 4. 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.
- 5. 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.
