<jdh30> hi
<mbishop> Hello
<jdh30> Hi Martin, how you doin?
<mbishop> Good
<mbishop> You?
<jdh30> Very well, thank you. Just writing an F# Journal article before I get back to F# for Scientists... due at Wileys in 2 weeks!!!
<jdh30> Wish I'd read that LaTeX book sooner. ;-)
<mbishop> Speaking of, I saw "Expert F#" is supposed to be out this month?
<jdh30> Yes indeed. Don's made me privvy to prereleases for reviewing and I must say its a bloody good book!
<jdh30> Robert Pickering's is a solid introduction (particularly for OOP people) but Expert F# is just wicked.
<jdh30> I spent the last week trying to grok "asynchronous workflows"...

<flux> cairo is ok for drawing charts: http://www.modeemi.cs.tut.fi/~flux/ovi/
<flux> (those are statistics on how the door to a local university computer club has been open)
<tristram> you draw with cairo from caml ? (and how do you read those charts ?)
<flux> yes
<flux> they are the number of seconds the door has been open at different times of day, drawn on a 12-hour clock face
<flux> dark segments are for night, light segments for day time
<flux> and the roman numerals are rotated, hence IIX for XII ;)
<tristram> oh ok; stupid me... i wondered why there are to numbers for the same time

<chris2> hi, where can i find a description of the new "reloaded" syntax?
* Yoric[DT] is fighting revised syntax problems atm.
<chris2> i dont mean revised
<flux> what do you mean, then? I haven't heard of that..
<chris2> it's new in 3.10 i heard
<flux> unless you pdrhaps refer to the whitespcaace-sensitive ocaml parser, but it doesn't xsound like it.
<flux> oh, dunno about that ;)
<chris2> there is an indentation-based parser?
<flux> yes
<flux> I don't remember its name, though
<chris2> hrm
<flux> it uses the preprocessor for doing the trick
<chris2> "I do like the "reloaded" syntax included with 3.10 that is basically original syntax with "end" after various constructs."
<Yoric[DT]> flux: "twt"

<flux> hm, fun bug with an ubuntu's ocaml-cairo.. my program works fine, but if I try to compile a toplevel, I get "The external function `ml_cairo_trasnform' is not available"
<wy> Is there a good ocaml-mode or ocaml editor around?
<c> both
<wy> I'd prefer the latter if it exists
<tristram> I only got convinced by tuareg (mode for emacs) though i usually don't use emacs
<Smerdyakov> Emacs is THE platform for functional programming.
<Smerdyakov> It might have some flaws, but it's the standard. New tools tend to be for Emacs.

<flux> does someone use cameleon, for real? I've never even managed to make it start..
<wy> I tend to use something like Eclipse recently, but it's unfortunately not for FP
david_koontz has quit []
<c> flux cameleon installed on debian sid, but toplevel was broken
<c> compiling it now on gentoo
<c> Unbound value Glade.create
<c> shouldnt that be part of lablgtk? hmm
<c> nm. gentoo modularized the crap out of lablgtk

<mbishop> Anyone here use the graphics module? I am making a simple program to flash colors, and it works, but if I move the window
<mbishop> it just disappears and exits
<asmanur> mbishop: what is the code ?
<mbishop> lemme paste it
<asmanur> hm
<asmanur> mbishop: it's strange because it seems that a X-event make the sleep call stop
<mbishop> weird

<RobertFischer> Hey there. Anyone alive?
<Smerdyakov> Lo, but we are deceased
<RobertFischer> Well, that's a shame.
<mbishop> asmanur: any idea on how to fix it?
<mbishop> or if it's even possible to fix? :P
<asmanur> mbishop: hum
<asmanur> i don't remember sleep() has this comportement in C, so it's maybe due to Graphics/Unix module :p
<mbishop> that must be it
<asmanur> yes
<mbishop> Hmm, any alternatives, or should I just make a function that does nothing for a second? :P
pants1 has joined #ocaml
<mbishop> Just removing the sleeps makes it go WAY too fast heh
<asmanur> mbishop: maybe with a ignore (read_key ()) ? but you need user input :/
<mbishop> perhaps I should just use SDL to get rid of the problem

<tristram> good evening, stupid question : i have 2 float arrays a and b of same dimension; I would like that b gets the same values as a (ie. b.(0) <- a.(0); b.(1) <- a.(1) ...)
<tristram> is there a simple/short/clever way to do that ?
