Welcome to issue 204 of the HWN, a newsletter covering developments in the Haskell community. This release covers the week of October 9 to 15, 2011.
New and Updated Projects
- lhs2tex-hl (Alessandro Vermeulen; 1.4.3) Upgraded package builds with GHC 7.2.x.
- global-variables (Jean-Marie Gaillourdet; 1.0) A package providing a global namespace for IORefs, MVars, and TVars.
- vector-bytestring (Bas van Dijk; 0.0.0.0) "The very ambitious goal of this package is that it will eventually replace our beloved bytestring package. By basing this package on vector, we can benefit from all the optimizations (like stream-fusion!) in that library."
- simple-actors (Brandon Simmons; 0.1.0) An eDSL library for actor model concurrency.
- ircbot (Jeremy Shaw; 0.1.1) ... "becase that's what Haskell really needs -- another irc bot library."
Quotes of the Week
- Pseudonym: A type is a collection of values, and a class is a collection of types.
- xplat: you just need to write a corresponding set of modules for well-hung coinduction
- Porges: State is stored in spacesuits. [via: reddit]
- [djahandarie] Group projects are stupid [shachaf] Try a semigroup project sometime. You need to lose your identity.
