Check out the blog. i scanned through http://www.galois.com/blog/category/haskell/ and don't found anything about this. probably we mean different things - i'm saying about implementation of cpu-intensive algorithms like deflate, md5 or mpeg for crypto-algos we have haskell library and afair it was 3-10 times slower than C equivalents and probably harder to write too? -- Best regards, Bulatmailto:bulat.zigans...@gmail.com ___ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe

Hi Jamie, As a side note - I'd be very interested to see a Haskell implementation of H264 decoding. I'm currently having to use the ffmpeg library in C, and it's notoriously buggy with memory leaks left right and centre. A haskell solution would be very much welcome! Regards, Chris.

Really? How does performance relate to it being possible to write? I would be surprised if it was indeed impossible to get something that runs fine one *some* machine. It may be difficult to beat C, but that doesn't mean it's impossible to write something useful. -- Sebastian Sylvan +44(0)7857-300802 UIN: 44640862 ___ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe
