apfelmus - FRP - Slides from the tutorial session in Halle
Hello everyone, last Friday, I gave a tutorial session on functional reactive programming (FRP) with reactive-banana at the HaL 7 - Haskell in Halle/Saale meeting. The tutorial was split into two parts: first a 30 minutes talk where I introduced the basic concepts and then one hour of live demonstration, where I sat down in front of a computer and implemented some examples in a dialogue with the a

update: updated for Yesod 1.2 tl;dr: A simple Yesod tutorial. Yesod is a Haskell web framework. You shouldn’t need to know Haskell. Its efficiency (see Snap Benchmark & Warp Benchmark1). Haskell is an order of magnitude faster than interpreted languages like Ruby and Python2. Haskell is a high level language that makes it harder to shoot yourself in the foot than C, C++ or Java, for example. One o

Abstract In this tutorial, we describe how to use monad transformers in order to incrementally add functionality to Haskell programs. It is not a paper about implementing transformers, but about using them to write elegant, clean and powerful programs in Haskell. Starting from a

Learn You Some Erlang for Great Good!
Hey there! This is Learn You Some Erlang for great good! This book is for you if you’ve got some programming experience and if you’re not too familiar with functional programming. It can still be useful if you’re too good for that, as we progressively go into more and more advanced topics. The book started as a free online guide, and you can still read it that way. If you prefer the soft touch of
