00:28 rrenaud: eli: i was maybe importing code wrong?
00:28 rrenaud: i had #lang at the top of a foo-test.rkt
00:29 rrenaud: and i included foo.rkt
00:29 rrenaud: which also had a #lang
00:29 eli: That would be another way to get such a problem.
00:30 eli: Code that is `include'd should be plain code, not a module.
00:30 eli: (Since it's actually included, and you can't write a modele inside another.)

01:58 rrenaud: SingAlong: i am pretty new to racket/scheme in general and so i don't know the terms, but it's the difference between strings (?) and atoms
01:58 rrenaud: it's comes down to the difference betwen foo and "foo"
02:11 SingAlong: rrenaud: oh so there's strings and atoms... thanks! i'll find out and read about it. I didn;t know there was something called atoms... I'm going thru the quick intro to racket page
02:16 SingAlong: rrenaud: i cannot find any page on atoms in the racket guide. can you point me to one?
02:16 rrenaud: atoms are just the building blocks
02:17 rrenaud: so i kind of mislead you, strings are atoms
02:17 rrenaud: but so are functions, ints,
02:17 rrenaud: basically the most nested part of the syntax
02:19 rrenaud: apparently atoms are an outdated concept from out lisp programming, "As more data types were introduced in later Lisp dialects, and programming styles evolved, the concept of an atom lost importance."

12:35 jonrafkind: whats the "best" solution for getting around the fact that bindings cannot be used before their definition in the transformer phase?
12:36 jonrafkind: as in http://paste.lisp.org/display/121014
12:36 jonrafkind: ive seen (define y #f) (define (x) (y)) (set! y (lambda () 2)), but that seems ugly to me
12:42 samth: jonrafkind, (define-values (x y) (letrec ([x ...] [y ...]) (values x y)))
12:42 jonrafkind: is the transformer fundamentally different from the runtime phase such that this is required in the first place? it seems like a bug to me
12:48 samth: (a) it is fundamentally different
12:49 samth: (b) why do you ask these questions on IRC when the world experts are in your office?
12:49 jonrafkind: its just a tad easier to ask here
12:49 jonrafkind: dont have a cow man

14:53 tewk: samth: GCC just genereates a makefile and calls make.
14:53 tewk: http://mad-scientist.net/make/jobserver.html describes how the jobserver works.
14:53 samth: tewk, that seems like cheating :)
14:54 tewk: Yep
14:55 tewk: I think the answer is to get make to spawn setup as if it was a recursive make invocation and just count the characters we can read off the jobserver pipe file descriptor as and indication of the number of jobs we should luanch.
14:55 tewk: Its messy, I've put it on my todo list.
14:55 samth: that looks vaguely right
14:56 samth: if only it just put -j N in the environment variabel
14:56 tewk: The question is can we trick make into launching racket as if it was $(make).
14:56 tewk: I think I need to download and look at the gnu make source.
14:56 samth: yeah, you just put + in front of the command in the makefile
14:56 (quit) Glav: Quit: (let ((call/cc (call/cc call/cc))) (call/cc call/cc))
14:56 samth: the gcc thing talks about that
14:58 tewk: I need to read read that part, hopefully (+) is enough for it to leave the jobserver fds open when it fork/execs racket.
14:59 tewk: re-read
15:02 tewk: samth: I also have your racket, raco, compiler suggestions for parallel make almost ready to checkin

15:02 (quit) anRch: Quit: anRch
15:02 samth: tewk, one other (harder) thing to think about
15:03 samth: i want to parallelize the Typed Racket typechecker
15:03 samth: but this seems hard with both places and futures
15:04 samth: futures because lots of things aren't threadsafe yet
15:04 samth: places because i can't share syntax objects with other places
15:04 tewk: futures probably isn't the right answer, we should be able to get place to work.
15:05 tewk: the syntax objects are immutable right?
15:05 samth: theoretically
15:05 samth: but they're mutated in the impl
15:05 samth: perhaps all the lazy mutations could happen when they get passed over the wire
15:05 samth: but that sounds like a lot of work for matthew
15:06 samth: but it's something to think about
15:06 samth: i'm happy to experiment, since anything that makes TR faster would be good :)
15:07 tewk: ryan, jay, and I have also talked about using serializable closures to make the message passing part of places more natural to the scheme programmer.
15:07 samth: tewk, the haskell folks have a paper that's partly about this that they submitted to ICFP
15:07 samth: http://research.microsoft.com/en-us/um/people/simonpj/papers/parallel/
15:09 tewk: I'll read it thanks for the pointer.
