Welcome to issue 203 of the HWN, a newsletter covering developments in the Haskell community. This release covers the week of October 2 to 8, 2011.
Eric Y. Kow has released the 6th issue of the Parallel Haskell Digest.
Janis Voigtlander issued an invitation to send in contributions for the 21st edition of the Haskell Communities & Activities Report. The more the merrier!
New and Updated Projects
- clientsession (Felipe Almeida Lessa; 0.7.3.1) Fix for security vulnerability.
- hit (Vincent Hanquez) An implementation of low level git operations to read and write to a git repository.
- OpenCL (Luis Cabellos; 126.96.36.199) An aparent fork of OpenCLRRaw package, done due to lack of updates from upstream.
- HaTeX (Daniel Diaz Casanueva; 3) A set of combinators which allow you to build LaTeX code, following the LaTeX syntax in a type-safe manner.
- Parsec (Antoine Latter; 3.1.2) A minor point release to the popular monadic combinator library.
- knob (John Millikin) Allows creation of memory-backed handles.
Quotes of the Week
- heatsink: Maybe, (), and Bool go to the Lone Star Bar. The bouncer stops Maybe and says, "we don't serve your kind here."
- DanBurton: correction - there will always be a job for programmers to write code to share pictures of cats
what we need is an adapter package any-lens which uses whichever lens package is available then we get potentially the disadvantages of all, without being able to guarantee the advantages of any.
- mauke: Go too considered harmful
- ddarius: isJust :: Maybe a -> Bool; isJust = unsafeCoerce
- ddarius: Well when people say you need a PhD to program Haskell, you can point out that SPJ doesn't have a PhD.
