Friends I'm giving a talk at a developer conference in London on Friday 18th, about parallel programming in Haskell. http://skillsmatter.com/event/scala/functionalpx-2011/ad-1382 I know that some of you have been using Haskell for parallel or concurrent programming quite a bit, so this email is just to ask could you contribute a little vignette or story about using Haskell in a *parallel/concurrent* application that I could use to illustrate my talk? I can rant all I like about the glories of Haskell, but I'm a biased witness. It's much more convincing if I can illustrate with true tales from the trenches. I'm interested in both parallelism and concurrency, so for example the success of Warp in using Concurrent Haskell is in scope. I can't say a lot about any one example, obviously, but what would be great would be - an idea of how Haskell helped (esp if you have a head to head comparison) - code snippets that illustrate how lovely it all is - brief performance indicators *Insight* is the key word. I don't just want to say "Company X used Haskell to do Y" because that doesn't convey any re-usable insights or ideas. What is the essence? I'll start writing in earnest on Monday 14th; the talk is on Friday. I have plenty to say already, so treat this as an opportunity not an obligation. But still, examples would be good! Do let me know if you have one. Simon
