03:19 <rumpl> Hi, is this good or is there a better way of doing lists in ocaml? http://rafb.net/p/b1Hq3Y68.html

03:23 <rumpl> Of course, there are already lists in ocaml...

07:18 <gaja> Hi. I'm trying to understand how to get the module DynArray to work but it seems ocaml can't find it. I'm quite new at using ocaml so I may well be missing a quite basic step. Or maybe it's not installed, I don't know if it is installed via ocaml-libs in debian. Any advice on how to start?

07:28 <pango> ocamlopt -I +extlib -ccopt ...

07:29 <gaja> Ahh.. cool. I'm sure there is some place I would have found this had I read it. Where could that be?

07:29 <gaja> And yeah thanks pango. =)

07:29 <pango> or if you have findlib, ocamlfind ocamlopt -package extlib ...

07:31 <pango> I used the latter with -verbose to see how it's expanded ;)

07:34 <gaja> Hmm.. Still don't quite get it. What is it that those commands do? Should the ... be replaced by a call to the compiler or what? What about if I want to try out dynarray in the interpreter?

07:34 <pango> mmh actually -ccopt is not required

07:35 <pango> gaja: then findlib can help too :) echo '#use "topfind" ;;' >> ~/.ocamlinit then #require "extlib" ;; in the toplevel

07:38 <gaja> Yay.. Now it works in the toplevel. =)

07:39 <gaja> I have always the process of compilation and such to frustrate me. Never have been able to make make work and such. =) Gotta get on that.

07:39 <gaja> +found

07:42 <pango> ocaml 3.10 has a new tool called ocamlbuild that's supposed to relieve some of the pain... Haven't test it yet (still using 3.09.3)

07:44 <gaja> Me too.. I'm just getting started on quite a big project for me. Will surely need a lot of knowhow if I wan't to have more than one sourcefile and I do..

07:45 <gaja> I find that the best way to learn a new programming language is to get in way over your head.

08:28 <TFK> Howdy, folks. I'm writing a program that needs to generate lots and lots of random numbers, and I use the Random module for that. After profiling, it turns out that up to 40% of program execution time are taken up by that module. Is there anything faster out there?

09:13 <flux> tfk, if you don't need good random numbers, you could google the web for a trivial random number generator algorithm

09:13 <TFK> And if I do?

09:13 <flux> ..and then implement one..

09:13 <flux> tfk, or you could check out the openssl/gnutls binding libraries, they are likely to provide random number generators

09:14 <flux> if not by other means, then by generating an encryption key and encrypting a sequence of zeroes with it..

09:15 <flux> btw, what kind of program are you writing, if I may ask?

09:16 <flux> hmh, atleast the savonet bindings of openssl don't provide access to random functions..

09:16 <flux> you could also write a piece of C code that generates a bulk of random numbers by using some library

09:17 <flux> I'm off the irc for a while now, so happy hacking..

09:34 <ygrek> TFK, ocamlgsl provides mersenne twister

09:36 <TFK> flux, I'm porting Nanopond to OCaml, it's a small Artificial Life program. It does a lot of random genome generations... Nanopond actually comes with its own RNG, but I was too lazy to port that :-(

09:37 <ygrek> MT is rather fast, and ocamlgsl is a binding to C GSL library which is widely used and so you can expect effective implementation

09:39 <ygrek> also there is mathlib package (never tried it though)

09:42 <TFK> ygrek, thanks, I'll check it out :-)
