For a different type of background, Bryan O'Sullivan is the author of some of the best Haskell libraries out there. The de facto standard JSON parser/serializer is his doing, for example, and his Riak client is the best I've seen in any language. This guy really knows what he's talking about.

I'm very impressed with the amount and quality of libraries they have released on Github [1].

Going to use the following in my "webmachine in Haskell" project.

  - aeson: Fast json library [2]
  - pronk: load test webservers [3]
