Welcome to issue 153 of the HWN, a newsletter covering developments in the [1]Haskell community. It sure has been a while since we last saw one of these. Hopefully the dry spell for the newsletter is now a thing of the past. I sure hope you enjoy it, and give plenty of feedback. As you can see, there are some changes to the contents of the letter. The first, and major change, is the use of Reddit and StackOverflow as aggregators to interesting links around the net. The number of links on each sections is rather arbitrary, I'd be interested in hearing your thoughts about them. This current issue is missing an "Announcements" section, as I did not have any to put there this time around. Hopefully that will be solved as soon as you start sending them in. I decided that rather than keep on waiting to have all the right pieces in perfectly working order, the priority was to get the newsletter back in circulation as soon as possible. Tweaking can always be done along the way. Some of the sections that I would like to add are: a Hackage report, interesting conversations from the different mailing lists, general community announcements, job opportunities, and the occasional interview with some of Haskell's celebrities. A major event last week were the meetings in Baltimore. Don Stewart collected a list of some of [2]the papers that were presented at the Haskell Symposium. You can find [3]videos from the Haskell Implementors' Workshop, posted by Simon Marlow. From the looks of things, seems like we sure need more than a 767 to fit all Haskellers! Ok.

About the Haskell Weekly News New editions are posted to [29]the Haskell mailing list as well as to [30]the Haskell Sequence and [31]Planet Haskell. [32]RSS is also available, and headlines appear on [33]haskell.org. To help create new editions of this newsletter, please send stories to dstcruz * at * gmail * dot * com. The code used to produce this version of the newsletter is not yet publicly available, as it is a complete hack design to get things started again.
