Description: Polymorphically-typed lazy purely-functional programming.
 

CFP: Commercial Users of Functional Programming (CUFP); Boston, MA Sep 22-24 
  Greetings, I am helping with the organization of CUFP this year. It is an excellent venue for discussing the application of functional programming languages and techniques. The talks are usually quite lively, and presents a great opportunity to influence language direction and design, the audience being a mix of practitioners and academics.... more »

Is it possible to have a version of forkIO that allows 'thread-objects' to return values? 
  Ie. a forkIO with type signature IO a -> IO (ThreadId , a) Can such a thing be implemented without compromising paralelism?

Yesod/Persist (and/or general Haskell) problem 
  Hello there, as I'm very new to Haskell, could someone kindly push me into the correct direction of solving the following problem...? I started with Yesod's scaffolding application. Serving HTML generated from database content works fine, but is there an elegant way to create plain text responses iterating over database tables? Simple plain text... more »

Scalable and Performing Container for Network Packets 
  I would like to solicit suggestions for the 'best' mechanism (in terms of scalability and performance) to use for the following problem: The code monitors multicast packets on a port. The packets are parsed into a data definition that extracts a set of fields which are a mix of Strings... more »

Video - Simon Marlow on High Performance Concurrency - Skills Matter's Haskell eXchange 
  Simon Marlow took the floor at the first annual Haskell eXchange last year to talk about high performance concurrency. Simon observes that the haskell community has been spending inordinate amounts of time designing beautiful programming models and APIs, whilst spending relatively less time building... more »

real-time frame stuff 
  Hello NG, I'm new in this NG and pretty new to haskell too, so hi to everyone. I am converting some of my image-processing routines from C to haskell, as I found it faster to experiment like this. First of all, I found a lot of libraries that do part of the stuff I need; what I figured out is that the way to go is REPA.... more »

Space leak 
  I had a space leak in a program that I distilled down to the following: main = print $ length (replicateM 15 "012") This should generate all the 15-digit ternary numbers (with leading 0's) so the length of the list is 3**15=14348907. It gets that result correctly, but uses almost a gigabyte of ram in computing it.... more »

Call-Site Code Replacement 
  Dear All, I just wonder whether it is possible in a functional language to do call site replacement. I envision this as a special form of lazyness. Basically I would call somewhere a function f with an argument a: ... (f a) ... The function would then manage to replace itself by a function g with an argument b:... more »
