I saw this and it made me very happy. I was going to mention it in my original comment but I couldn't remember the link. I'm going to put this in my "tutorial TODO" list, it looks like a lot of fun! Thanks :)

If you've had problems with cabal hell in the past and quit using Haskell, this might be your solution!

Theoretically you may be right, but in practice not so much. source: I've been writing production Haskell code for a little while now and haven't had any weird performance issues yet.

>> It may not be a race horse, but if you ported those improvements into something like C, you'll have a high-performance rocket. Code that could possibly automatically refactor itself into more efficient, more general components

Oh? I haven't seen those! I definitely need to look into it more.

Re: why racket isn't used more Last time I did some json parsing it was poetry slow. I've also heard the continuation based webserver was slow and uses a lot of memory. I'll have to benchmark again to be sure. I hope I'm

As I understand it in the Haskell community right now. 1. Pipes | Conduit 2. io-streams (perhaps not in 1 only because of a lack of popularity and it is new) 3. Iteratees (have some issue Pipes/Conduit do not which I can't recall)

I was in a bit of a hurry, so thanks!

> Brainfuck, Haskell, Lisp, Assembly, and a slew of other impractical My argument: Haskell and Lisp are just as practical as Python, Java, C#, or C++ for r/dailyprogrammer problems. Brainfuck is impractical, I can agree with that. H

With Go you have less type safety and no generics though.

LOL, and I spent all that time getting it to compile. Do you know if this compiles with GHC 7.8?
498.
by codygman 11y ago
I've gotten it compiling! Though I'm not as excited after just now noticing salamynder's comment: https://raw.githubusercontent.com/gentoo-haskell/gentoo-hask... I basically have the same modifications

Whoa... I'm surprised this is building (using ghc 7.8.3). I just did: darcs get http://code.haskell.org/frag cabal sandbox init cabal install It's still building right now. I'm expecting some f

by codygman 11y ago
I'm guessing it still runs on GHC 6.8, maybe GHC 7.6.3? It uses HOpenGL-2.0 and the current version is OpenGL-2.12.0.1 (with a name change apparently). I'll try to compile it.

I know, I was just adding on that I am sometimes jealous of you being able to say "Go is a pleasure to work in" when it isn't so much of a pleasure for me anymore.

by codygman 11y ago
> Go is a pleasure to work in. Java, less. Sometimes I wish I'd stopped at Go instead of then exploring Racket, Ocaml, Clojure, Haskell, and Scala so I could continue to hold your opinion. The end result still matters the most to me

Perhaps unsurprisingly, I'm very fond of the Haskell mongoDB package. Here's an example: import Database.MongoDB import Control.Monad.Trans (liftIO) main = do pipe <- connect (host "127.0.0.1&quot
