Welcome to issue 161 of the HWN, a newsletter covering developments in the [1]Haskell community in the week of November 28 - December 04. Jan Snajder [2]announced the release of genprog, a genetic programming library. Ian Lynagh informed us that the haskell.org server migration is now complete. There might still be some issues lying around, if you happen to spot one, please let the admins know. The biggest announcement this week came from Galois, Inc. on the [3]immediate release of the Haskell Lightweight Virtual Machine. "The HaLVM is a port of the GHC runtime system to the Xen hypervisor, allowing programmers to create Haskell programs that run directly on Xen's "bare metal."" Isabelle Perseil informed us that there is an [4]extension to the submission deadline for papers for International Conference on the Engineering of Complex Computer Systems (ICECCS) until December 15th. Gregory D. Weber [5]informed us of an update to his Sifflet tool, and sifflet-lib. "Sifflet is a visual, functional programming language and support system for students learning about recursion." This week we had 48 new StackOverflow questions, and 33 new Reddit stories. Hackage saw 108 uploads/updates from 59 distinct contributors. Most active uploaders to hackage were Michael Snoyman (16 uploads) and Andy Stewart (13 uploads). Big note of thanks to Janis Voigtländer and to Benjamin L. Russell for sending in bits for this newsletter. So, what went on this week?
