# 1 Generic Information

How to create repositories...

# 2 Active Projects

Please feel free to describe your current project here!

## 2.1 Cabal

## 2.2 ByteString network

Change Network.* to use strict ByteStrings instead of Strings. It would also be nice to tidy up the #ifdef mess.

Current hacker(s): tibbe (Johan Tibell)

## 2.3 Probability monads

A really cool existing implementation: Probabilistic functional programming

Darcs repository and draft paper.

Things to work on:

- Get MaybeT into Hackage.
- Is WriterT really the right monad transformer? We want the join and bind operations, but not the rest of the MonadWriter type class.
- Should probabilities be represented as floats, fractions or a type class?
- Can this run fast enough to be useful?
