Welcome to issue 156 of the HWN, a newsletter covering developments in the [1]Haskell community in the week of October 17 - 28. I did not manage to filter out good posts from Haskell-Cafe this week. If you see a thread in -cafe that you think would be good to share with the community, please do share it with me. I need to find a better way of keeping up with the mountain of posts to that list. There were a total of 34 new stories posted to the Haskell Reddit channel (+10), 47 new questions taged with Haskell in StackOverflow (+20), and 332 messages posted to Haskell-Cafe (-76). So, what was hot last week? Announcements John Hughes [2]announced that the Functional Programming group at Chalmers is recruiting a postdoctoral researcher for a two year position, starting as soon as possible. Wouter Swierstra [3]called for workshop and co-located event proposals for the ICFP 2011 in Tokyo, Japan. Zhong Shao [4]informed us that the Department of Computer Science at Yale University is seeking applicants for a PostDoc and PhD positions in the broad area of certified software. Josh Tripplett wrote in to tell us about Ore, a [5]packaging system for Ruby inspired by Haskell's Cabal! According to [6]this haskell community calendar, there are 2 events to take note happening next week: The Haskell Communities & Activities Report submission deadline on Nov 1, and BelHac (in Ghent, Belgium) on Nov 5 - 7.
