Welcome to issue 166 of the HWN, a newsletter covering developments in the [1]Haskell community. This release covers the week of January 16 to 22, 2011. Announcements Sukit Tretriluxana [2]proudly announced version 1.0 of SiteBridge. He also included a short introductory video. Mark Wright [3]annouced the release of a Haskell binding to ANTLR LL(*) parser generator C runtime library. Jasper Van der Jeugt [4]inveted everyone to the 6th Ghent Functional Group Meeting to be held on Feb 17, 2011 in the Technicum Building (Sint-Pietersnieuwstraat 41, 9000 Gent) of Ghent University. I know I'm not the only one who wishing I could attend!. Quotes of the Week * Guy Steele: Although Fortress is originally designed as an object-oriented framework in which to build an array-style scientific programming language, [...] as we've experimented with it and tried to get the parallelism going we found ourselves pushed more and more in the direction of using immutable data structures and a functional style of programming. [...] If I'd known seven years ago what I know now, I would have started with Haskell and pushed it a tenth of the way toward Fortran instead of starting with Fortran and pushing it nine tenths of the way toward Haskell. * geheimdienst:ah, yes. now we have to make a lambdacat captioned "kittehs no bery gud at speling. we says leksah fur lexer and monad fur moniod in catagory of ennobunktors" * mreh:some jerk said to me over my shoulder once, if you're doing functional programming, why do you have all those assignments? * revenantphx:You don't need category theory to understand Haskell, though you may need it to understand #haskell. * tolkad:haskell isn't even turing complete without infinite memory * monochrom:C-c C-p was the secret command for sending a report to the kgb * Draconx|Laptop:Rice's theorem: Let P be an interesting problem that you want to solve with a computer. Haha, you're screwed! * monochrom:one ring to rule them all! and in your monad >>= them!
