Welcome to issue 154 of the HWN, a newsletter covering developments in the Haskell community in the week of October 03 - 09. This community does not stand still! The last section of the newsletter contains a list of new or updated packages this passed week. All 87 of them! I had my doubts about listing them all, but there was encouragement from IRC folk to showcase them all, at least this time. If you are having a hard time filling your day with Haskell stories, make sure to jump into Reddit and help everyone by posting comments and voting on stories that are meaninful. If you manage to have time left after that, the volume of postings on the mailing lists is more than one person can keep up with. Send threads that you think the rest of the community would benefit from. For those of you who manage to have extra-extra time, you can use [1]twitterfall to try to keep up with the many tweets about Haskell! So, what was hot this week? Announcements Want to know what events are comming up in the community? Come and see the [2]Haskell Community Calendar. Send new events to dstcruz@gmail.com Michael Snoyman [3]announced and asked for advice on [4]Haskellers.com. If you are into Haskell, by all means, please stop by and make a profile on the site! A new version of the venerable Haskell XML Toolbox (version 9.0.0) [5]was announced by Uwe Schmidt. A package for tls, native TLS/SSL protocol implementation [6]was announced by Vincent Hanquez. Interesting Threads on Haskell-Cafe Petr Pudlak Asked if there are any suggested/recommended Haskell coding conventions? Perhaps something like Java has? [7]see thread caseyh commented of difficulties with GUIs working under Windows. The thread included talk about the state of Haskell GUI programming in general. [8]see thread Don Steward and Duncan Coutts presented a status report on the Haskell distribution infrastructure: Hackage, Haskell Platform and Cabal, during the Haskell Implementors Workshop held in Baltimore. You can find the [9]slides and the [10]video of the presentation. Christopher Done [11]annouced that he has been doing some refactoring on Haskell web development entries on the Wiki. Max Bolingbroke [12]told us about a proposed haskell feature: lambda-case/lambda-if. There seems to be interest from multiple people to see this feature. Some modifications to the original syntax were also proposed in the thread. Top Reddit Stories * Learn You a Haskell for Great Good! The Book!
