Welcome to issue 38 of HWN, a weekly newsletter covering developments in the Haskell community. Each week, new editions are posted to the Haskell mailing list as well as to the Haskell Sequence and Planet Haskell. RSS is also available, and headlines appear on haskell.org.

This edition mechanised, automated and published thanks to Text.PrettyPrint, hopefully making it easier to keep the weekly news schedule in future.

Announcements

• The GHC Hackathon . Simon Peyton-Jones announced that GHC HQ are going to run a hackathon, in Portland, just before ICFP this September (14-15th). It'll be held at Galois's offices, in Beaverton. Thanks go to Galois for hosting the meeting. Here are the details. If you are interested in finding out a bit about how GHC works inside, then you should find the hackathon fun. It will be informal and interactive. If you think you might come, please take a look at the above page, and register.

• Bytecode API library . Robert Dockins announced a release of an alpha version of a library for reading and writing the YHC bytecode file format. It reads and writes the entire bytecode set, version 1.9 (the one used by recent YHC builds). Check it out.
