05:56 tim-brown: mornin all
05:56 tim-brown: are there any plans to make racket threads into fulll OS threads?
05:57 tim-brown: futures seem a bit too granular, and places not granular enough

06:39 noelw: places are essentially os threads, as i understand
06:39 noelw: with controlled shared memory

06:44 (join) sindoc
06:52 tim-brown: any thread programming -> random craziness?
06:52 tim-brown: is shared memory the tough part of thread programming?
06:52 tim-brown: not synchronisation?
06:53 tim-brown: most of my bugs are deadlocks / runaway threads
06:54 noelw: I was being provocative, I admit
06:54 noelw: Shared memory gives rise to race conditions
06:55 noelw: All of my thread programming for … a very long time
06:55 noelw: has used something actor model esque
06:55 noelw: or at least higher level abstractions than just threads
06:56 noelw: so perhaps I shouldn't comment

10:48 klm: hi guys, I'm trying to learn racket as my first LISP language. I really like the diversity and the "clean code" that I hopefully will be able to produce soon
10:49 klm: I've run into a problem that I though would be more common: I have an infinite tream and I wish to pick out the first n elements and make that into a list.
10:49 klm: (stream->list (in-primes)) obviously hangs forever, which function I am looking for?
10:50 noelw: stream-take
10:51 klm: thanks, noelw, I tried that - but there seems to be no such function
10:53 noelw: Oh, it's in SRFI-41, not racket/stream
10:53 klm: ah, so there's a library somewhere I should (require)?
10:53 noelw: I'm not sure if they use a compatible stream representation
10:53 noelw: but you can try (require srfi/41)
10:54 (quit) ahinki: Quit: ChatZilla 0.9.88 [Firefox 10.0/20111228055358]
10:59 klm: I think you're right noelw, I says "non-stream argument"
10:59 noelw: Guess you have to write it yourself.
11:00 noelw: You should be able to base your code on the srfi-41 code
11:00 klm: ok, I'm gonna try that
11:01 noelw: srif-41 code here: https://github.com/plt/racket/blob/master/collects/srfi/41/derived.rkt
11:01 klm: thanks!
11:02 klm: (how did you find where the definition was so fast?)
11:07 klm: I've gotta run, so I have to look into that later. I appreciate the input, noelw!
11:07 noelw: np
11:07 noelw: Github trip: press t to get a file browser
11:07 noelw: A require statement srif/41 corresponds to a file 41.ss in collects/srfi
11:07 noelw: Go from there

13:24 tonyg: Is Racket's OpenSSL support roughly guaranteed to be present on all major platforms? I know *NIX and OS X ship with openssl almost always, but what about Windows? Perhaps the Racket distribution has OpenSSL in it?

14:27 chandler: only issue I had was that the included libcrypto didn't end up in a distribution, so I couldn't distribute programs using vyzo/crypto. this was on 4.x though; don't think I've tried building a windows distribution since that
