Join us at the next meeting of pdxfunc, the Portland Functional Programming Study Group, on Monday, 14th January, at CubeSpace. ------------------------------------------------------------------------ We'll have presentations, demos and discussions. We welcome programmers interested in all functional languages and our meetings have content for coders of all skill levels. If interested, please also subscribe to our mailing list at http://groups.google.com/group/pdxfunc PRESENTATIONS (1) Justin Bailey: Exploring Haskell's space and time profiling tools A presentation on the space and time profiling tools available for GHC Haskell, featuring slides and interactive demos. Heap profiling tools and methods will be discussed, along with a demonstration of how to use them to detect a space leak. Time profiling tactics will be covered using "cost-centre" annotations to help select candidates for optimization. Recommendations will be given on how to read the "Core" language with an eye for optimization. Justin Bailey (jgbailey@gmail.com) has been programming professionally for 12 years, and is currently a Computer Science master's student at Portland State University. Until 2006, he coded exclusively with object-oriented languages like Java and C#, but then discovered Haskell and hasn't looked back. He's released a Haskell library for building command-line applications called HCL, made contributions to several other Haskell libraries, and continues to hack Haskell every day he can. (2) Iavor Diatchki: Writing parsing combinators with Haskell A presentation on parsing combinators, given as a hands-on demonstration for developing a small library to parse JSON data using Haskell. The entire process will be shown from scratch, starting with defining the concept of JSON values, using pretty-printer combinators to turn values into strings, and finally using parser combinators to turn strings into values. Iavor S. Diatchki is an engineer at Galois Inc., where he uses functional programming for the development of high assurance software. Iavor obtained his PhD degree in 2007. His research focused on various aspect of using functional languages for the development of low-level systems software such as OS kernels.
