10:39 gelph: What is the common wisdom about distribution to multiple platforms?  Does one create binaries for each platform, or does one require racket to be installed then provide the script source code?
10:40 bremner: I'd say it pretty much depends on your audience.
10:41 (join) tauntaun
10:41 gelph: Note taking software (command line first, then gui, "access from anywhery", think dropbox or evernote, maybe a mobile app too)
10:43 bremner: ah, sounds like binaries would be most suitable. Unfortunately they are a bit big.

13:15 rekahsoft: hi all..i have been doing some problems from projecteuler.net and stuff with crypto just for kicks but i noticed something that made me wonder..
13:19 rekahsoft: i wrote what i though was a super fast fibinocci function..but when i execute it on my quadcore i oly see one cpu spike..how can i make it use all cores? do racket threads work for this?
13:20 offby1: nope
13:20 offby1: alas
13:20 offby1: there's some work in progress to allow racket to use multiple cores, but it's still early days yet
13:20 (quit) realitygrill: Quit: realitygrill
13:20 rekahsoft: offby1: awe :S so i'm out of luck eh?
13:21 offby1: far's I know.
13:21 rekahsoft: any idea if common lisp supports multiple cores?
13:21 offby1: dunno.
13:21 offby1: I bet Clojure does, though :)
13:22 JohnnyL: rekahsoft: python does

13:28 Daemmerung: jonrafkind: that doesn't help you when your office is cold
13:29 Daemmerung: perhaps it could titrate the degree of memoization based on a calendrical calculation

16:31 Daemmerung: An Inside question, or rather a confirmation: the result of a call to scheme_make_byte_string() is not GC'd unless I take steps to register that returned value with the collector, right?
16:31 offby1 shifts uncomfortably
16:31 Daemmerung: (I'm trying to understand readline/mzrl.rkt's custom ctypes.)
16:31 offby1: will this be on the test?
16:31 Daemmerung: God, I hope not.
16:37 mithos28: is there anything like struct-out but that works in reverse (i.e. for require instead of provide)?
16:37 Daemmerung: Pertinent semi-mystifying ctype is _bytes/eof/free in mzrl.rkt; specifically, how it's registering its finalizer, and how that differs from _string/eof/free.
16:38 offby1: mithos28: interesting question ... dunno
16:43 Daemmerung: mithos28: can you provide a concrete example?  You want a finer-grained import than (require m), but broader than (require (only-in m single-binding))?
16:44 mithos28: I am trying to fix require/typed's struct import, and am looking to see if some one else solved my problem already
16:45 mithos28: the problem is some structs export different constructors depending on whether they were made with define-struct or struct
16:46 mithos28: a user knows which one they want, but I am trying to figure out how to do that programatically
16:49 offby1: ah, so you want (require (struct-stuff m structure-type-id)) where it always does the right thing
16:49 offby1: dunno about typed racket, but I doubt that'd be that useful in regular racket: when I define a struct in module s, I typically do _not_ export all of the automatically-defined names
16:50 offby1: instead, I generally write a wrapper constructor, which does sanity checks before calling the automatically-defined constructor, and I export _that_
16:53 mithos28: I usually do export all the names, through provide/contract to do the sanity checking
16:55 offby1: I seem to recall having some constraints that couldn't be checked with contracts ... either that, or I didn't know how to use contracts :)
16:55 mithos28: I now actually think it isn't even possible, because the available information isn't enough
