--------------------------------------------------------------------------- Haskell Weekly News http://sequence.complete.org/hwn/20081122 Issue 94 - November 22, 2008 --------------------------------------------------------------------------- Welcome to issue 94 of HWN, a newsletter covering developments in the [1]Haskell community. Lots of interesting reading this week! Martin Escardo writes about [2]finite search over infinite search spaces expressed as a monad; Conal Elliott writes about [3]the unambiguous choice operator and [4]merging partial values; Luke Palmer on [5]restricted data types and [6]Udon, his system for universal distributed object management; a post about [7]incremental parsing in Yi; Ryan Ingram on [8]parametric higher-order abstract syntax; Issue #12 of [9]the Monad.Reader; and much more! Announcements The Monad.Reader - Issue 12: Summer of Code Special. Wouter Swierstra [10]announced Issue 12 of [11]the Monad.Reader, featuring articles by Max Bolingbroke, Roman Cheplyaka, and Neil Mitchell describing their Summer of Code projects. Turbinado V0.1. Alson Kemp [12]announced the release of [13]Turbinado, an MVC web framework for Haskell. EEConfig-1.0. Bartosz Wojcik [14]announced the release of [15]EEConfig, a simple library for reading parameters from a configuration file. Discussion Proof of a multi-threaded application. Silviu Andrica [16]asked about the possibility of proving the correctness of a multi-threaded application written in Haskell, leading to a discussion of STM, model checking, and related issues. Monadic bind with associated types + PHOAS?. Ryan Ingram [17]wrote about using parametric higher-order abstract syntax to get the benefits of HOAS (using the embedding language to express binding and substitution) while still being able to inspect or optimize the resulting expressions.
