01:26 blahblaghbla: about dr.racket
01:26 ttuttle: Go ahead and ask.
01:26 ttuttle: I probably don't know the answer, but someone else might.
01:26 blahblaghbla: is there some sort of function that will round to the nearest positive integer?
01:27 blahblaghbla: like (round-to-positive -5000) would evaluate to 0
01:33 jon2: (round (inexact->exact (max n 0))) or something
01:34 jon2: (nn 1.3) => 1; (nn 1.8) => 2

03:00 Lajla: samth, you're probably the guy who knows how I can within a reasonable timeframe racket up the list of all primes lower than 2 million right?
03:02 Lajla: Even the mighty sieve was bested by this.
03:03 samth: the sieve is not a good prime-finding algorithm
03:04 samth: i recommend google
03:10 Lajla: But google works a lot less efficiently on variable input. =(

I cannot execute 'ssh git@git.racket-lang.org' successfully because it is asking for a password.  Above, it says "and you should be able to connect to this account using the ssh identity key that corresponds to the public key that you use with the git server."  Well, I haven't used a public key with the git server yet, so I'm a little confused.
15:41 jsnikeris: Is there a public key listed somewhere?

16:37 jsnikeris: ok thanks
16:37 jsnikeris: and if I want to submit a patch?
16:41 jsnikeris: Another question: So the windows binary distribution includes a bunch of source files for DrRacket.  Is it possible to edit these files and test the changes without recompiling everything?

17:32 stamourv: patches are always appreciated!
17:33 sstrickl: stamourv: pong
17:33 stamourv: and for your other question, if you only change the .rkt files, you don't need to recompile everything. running raco setup will compile only what's necessary
17:33 stamourv: sstrickl: did you write the dict contracts implementation?
17:34 sstrickl: stamourv: no, ryanc did
17:34 stamourv: sstrickl: I see. do you know anything about it?
17:35 sstrickl: stamourv: Generally, but not anything about the real specifics.  Ryan and I have talked about it, but I don't have the details on the tip of my tongue at the moment, and haven't gone back to look over the code since.
17:35 stamourv: using pretty much any dict function results expands into calls to contract-related stuff internal to racket/dict
17:36 stamourv: which makes the expansion not really typeable
17:36 stamourv: we'd have to special case all of them, not really interesting
17:36 sstrickl: ah, gotcha.  Yeah, I'd send Ryan an email about it and discuss it with him then.  I'll also mention you're running into this issue next I see him here.
17:37 stamourv: alright, thanks
17:38 sstrickl: stamourv: just send him the email also in case I forget :)
17:47 stamourv: I'll do that
