Hi all, I have yet another question. I think I have too much time on my hands. I have two functions: > rf :: (RealFloat a, Integral b) => [a] -> b -> Complex a > rf x k = ... > cf :: (RealFloat a, Integral b) => [Complex a] -> b -> Complex a > cf x k = ... I would like to add these to

Database Mailing List

2003-01-22 Thread Dominic Steinitz
There seems to be a small group of Haskell users who are interested in building and using interfaces to databases. Would it be possible to set up a mailing list for those interested? I'd be happy to administer it if required (although someone would have to show / tell me what needs doing). Domini

Hello Everyone, I believe that haskell would have great benifit from a platform independant specification for a graphical user interface module or set of modules. I've been blessed with a lot of time on my hands so I'd be willing to organize this project if needed. Since there are several wo
