[Haskell-cafe] Timing difference

Programming for Rosetta Codes task http://www.rosettacode.org/wiki/Probabilistic_Choice I observed a remarkable (that's to say: for me) difference in timing using lambda function in the one case and point free in the other. Timing was measured in GHCi. Compiled there's no difference! Using

Re: [Haskell-cafe] Timing difference

Hi Bulat, That I (can) understand, but of course the main question is: is point free in (some/several/all) cases faster than the more readable lambda construction? That's to say when executed in GHCi. I noticed this behavior before (pity I haven't other examples at hand). In prog. lang. J (

Compiled timing (point free version: doesn't matter though as mentioned by Bulat): .. ghc -O2 ./../Puzzels/Rosetta/probabilistic_choice.hs -o proba .. time ./proba ... real0m9.975s user0m9.765s sys 0m0.212s GHCi: (12.26 secs, 2470869600 bytes) So about 20 pct faster than

[Haskell-cafe] ANN: Hieroglyph 0.85

I have changed the name of Thingie to Hieroglyph and added support for displaying images on the Cairo canvas. I'm still working on using template haskell to derive the basic UIState class, but I don't understand template haskell all that well, so it's taking some time. Hopefully I can get some

[Haskell-cafe] Hackage packages for indexing by Google

When testing the ShowMeta parallel web: http://hackage.haskell.org.showmeta.parallelnetz.de/packages/archive/pkg-list.html I found, that all HackageDB pages forbid crawling and indexing. Actually, the content of this page is dynamic - but it changes only incrementally. It would be very

[Haskell-cafe] Re: How does one use Text.Regex.Base.RegexLike?

Yeah! I am glad the mailing list has helped. If you get stuck or need something fancier then let me know (I wrote RegexLike). But I still don't know how to get makeRegex to work. You need it to specify options like case insensitivity, or to use functions like matchAllText. Well, the
