05:01 (nick) Guest22744 -> wwall
05:01 wwall: hello
05:02 wwall: anybody can help me?

05:11 wwall: thanks? but i see this docs? and dont understand as i can do 2 page ( first - register user, second - hello for him)
05:12 wwall: sory my bad English
05:15 eli: This is a tutorial for how to use the web server.
05:16 huma: up/down keys don't work for me in interpreter. do you think it might be a readline problem?
05:16 wwall: ctrl+up row
05:16 wwall: row = key
05:17 huma: nope
05:18 wwall: eli, exists any other document about web in racket?
05:22 huma: wwall, what version are you using? built from source?
05:23 wwall: huma, no.
05:29 eli: huma: Are you using the "drracket" IDE, or the "racket" command-line.
05:30 eli: wwall: There are plenty -- ask on the mailing list and you'll probably get lots of pointers.
05:39 huma: eli, the latter. i had a similar issue with ruby's interpreter built against the wrong readline version. thought maybe it's the case here. i have a binary package from my distro though, which should be tested (in theory :)
05:39 eli: Are you on linux?
05:41 huma: archlinux
05:44 eli: huma: Did you read this: http://docs.racket-lang.org/readline/ ?
05:46 huma: gah! it works :)
05:46 huma: simple (require readline) fixed it
05:46 huma: thanks
05:47 huma: ok, i should rc it then
05:48 eli: huma: The reason it's not on by default is explained at the bottom of that page.
05:48 (quit) wwall: Quit: Ухожу я от вас (xchat 2.4.5 или старше)
05:50 huma: eli, oh... thank you
05:50 huma: this should probably be on top instead :)
05:51 eli: The top explains how to use it.  (Besides, most people are not on a linux terminal...)
07:00 askhader: eli: wtffff
07:01 askhader: have none of that blasphemy in here
07:06 eli: askhader: Most people are on windows.
07:06 eli: Some of those who are not are on some OSX gui.
07:06 eli: Some of those who are neither are using DrRacket.
07:06 eli: Some of those who are none of the above are in Emacs.
07:07 eli: That leaves around 3 people...

07:36 pdelgallego: hi, I want to learn a lisp dialect this summer, I was wondering what are the pros and cons  of learning racket over scheme or clojure.
07:37 pdelgallego: I have copy of the sicp book and the onLisp book that I am planning to use to learn from.
07:39 bremner: well, learning racket and learning scheme have a lot in common...
07:40 pdelgallego: bremner, so what is the main difference between them when learning.
07:41 bremner: I'm not expert enough to answer your question, just to point out that until about 1 month ago, racket was called PLT scheme.
07:42 pdelgallego: I see. so they are quite close
07:42 bremner: I guess racket or some other scheme would be better for sicp than clojure. But you could discuss that on #scheme.
07:43 pdelgallego: kk
07:43 eli: pdelgallego: if you want to go through sicp, then racket will be fine.  There's a package that is intended for that here: http://www.neilvandyke.org/sicp-plt/
07:44 pdelgallego: eli, ohh that is great.
07:47 bremner: eli: would it be fair to say that racket is more "learner oriented" as a project than some of the other scheme-variants?
07:48 eli: bremner: No.  It's was common myth that "PLT Scheme is good for learning, and when you're done learning you move to some serious implementation".
07:48 eli: s/'s//
07:48 eli: It was never true.
07:49 bremner: Yeah, I didn't mean it like that (and wouldn't know anyway), but for example there is more effort to a GUI and integration with texts.
07:49 eli: There's a strong stress on learning, but that doesn't mean that it's any less capable as a working tool.
07:50 eli: You could say that it's more oriented towards learning as long as its clear that "more X oriented" doesn't mean "less anything else oriented"...
07:50 bremner: fair enough.

18:49 cwearl: I have a question about equal? and equal-hash-code:  When can two objects be equal but have different hash-codes?
18:50 cwearl: Code from DrRacket:
18:50 cwearl: > (equal? error-ele error-set-ele)
18:50 cwearl: #t
18:50 cwearl: > (equal-hash-code error-ele)
18:50 cwearl: 655929893
18:50 cwearl: > (equal-hash-code error-set-ele)
18:50 cwearl: 186318028
18:51 cwearl: > The two objects in question are structures with syntax objects, sets (based on equal) and sets of sets.
18:54 jonrafkind: set has its own prop:equal+hash
18:56 jonrafkind: hm, but looking at its implementation it seems like when two sets are equal? they should have equal hash codes as well
18:59 cwearl: If it helps at all, this problem is intermittent:  One run, all the hash-codes are consistent, and there are no problems.  Another run, I get behavior similar to the above REPL.
18:59 jonrafkind: all within drracket, right?
19:00 cwearl: This problem has appeared for me on the command line as well.  There though, the problem is consistent.
19:01 jonrafkind: you could try disabling debugging in drracket to have a more consistent experience
19:01 cwearl: Small changes to my code do give wildly different results on the command line.
19:01 jonrafkind: language -> choose language -> dynamic properties -> no debugging
19:03 cwearl: I've changed to no debugging, but the inconsistency remains.
