Welcome to issue 95 of HWN, a newsletter covering developments in the Haskell community.

Real World Haskell is finally here! Read it online, and/or get your own dead tree copy. Better yet, get two copies, one for yourself and one for a friend. The fifteenth Haskell Communities and Activities Report is also here---check out all the exciting stuff being worked on in the Haskell world!


HCAR. Janis Voigtlaender announced the 15th edition of the Haskell Communities and Activities Report (HCAR) is now available!

Not quite another Haskell tutorial, but .... Janis Voigtlaender announced that he submitted his Habilitation thesis last week. The first few chapters of it try to give an introduction to Haskell with emphasis on types and reasoning principles.

hledger 0.2. Simon Michael announced version 0.2 of [http://joyful.com/hledger hledger, a minimal haskell clone of John Wiegley's "ledger" text-based accounting tool.

darcs zlib error workaround. Eric Kow outlined workarounds and future plans for a darcs bug relating to broken CRCs in gzipped patch files. You should read this if you have installed darcs 2.1.2 via the Cabal build method.

Turbinado 0.2. Alson Kemp announced version 0.2 of Turbinado, an easy-to-use, fast web application framework.

Fun with type functions. Simon Peyton-Jones requests examples of compelling use cases for type functions: "can you tell us about the most persuasive, fun application you've encountered, for type families or functional dependencies? Simple is good. It doesn't have to be elaborate: just something that does something useful you could not have done otherwise."


PhD Positions in Language-based Security at Chalmers. Andrei Sabelfeld announced the availability of PhD student positions in programming language-based security in the Department of Computer Science and Engineering at Chalmers University of Technology, Sweden. The application deadline is January 30, 2009.

FP Jobs. Julien Sylvestre announced several new permanent positions, based in Paris, with MLstate -- an IT company whose functional programming approach to SaaS and cloud computing has been recently recognized by the French Ministry of Research Innovation Award.
