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. You can find a HTML version of this issue at: http://contemplatecode.blogspot.com/2011/10/haskell-weekly-news-issue-203.ht... Announcements Eric Y. Kow has released the 6th issue of the Parallel Haskell Digest. [1] http://goo.gl/zyIWX Janis Voigtlander issued an invitation to send in contributions for the 21st edition of the Haskell Communities & Activities Report. The more the merrier! [2] http://www.mail-archive.com/haskell-cafe@haskell.org/msg93759.html New and Updated Projects * clientsession (Felipe Almeida Lessa; 0.7.3.1) Fix for security vulnerability. [3] http://goo.gl/Ot8d1 * hit (Vincent Hanquez) An implementation of low level git operations to read and write to a git repository. [4] http://goo.gl/bVxHw * OpenCL (Luis Cabellos; 1.0.1.3) An aparent fork of OpenCLRRaw package, done due to lack of updates from upstream. [5] http://goo.gl/bVxHw * 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. [6] http://goo.gl/zuW36 * Parsec (Antoine Latter; 3.1.2) A minor point release to the popular monadic combinator library. [7] http://goo.gl/Gx6Y3 * knob (John Millikin) Allows creation of memory-backed handles. [8] http://goo.gl/Jq7kl 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 * quicksilver: 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.
