00:57 hyungrok: Umm, I used the PLT PPA (private package archive).
00:57 hyungrok: racket -v says it's 5.1.
00:58 eli: In that case it's a good idea to post on the list.
00:59 eli: I think that there was some ubuntu related thing that was discussed, but I'm not sure.

14:53 Znudzon: Hi. I've wondering . Racket is using only for education or maybe in commercial programming ?
14:55 bremner: Znudzon: I don't understand your question. Are you asking if racket is used commercially?
14:55 Znudzon: yes
14:56 (join) anRch
14:57 bremner: I have heard of a few cases, but it is difficult to know. People don't usually talk about commercial projects.
14:57 bremner: but it is certainly reasonable to assume much less than java
14:58 bremner: Znudzon: what is your motivation in asking?
14:59 offby1: Znudzon: it's hard to know what it's used for, since users aren't required to register or anything.
14:59 Znudzon: I'am bored with java on my university
15:00 offby1: if all you want is to relieve boredom, then racket is an excellent choice :)  That's what I mostly use it for.
15:00 Znudzon: and i'am searching for something new and useful
15:01 offby1: I recommend it, but then I would, wouldn't I :)
15:02 Znudzon: I thought that racket it's like Oz or something like that and was created only for teaching
15:05 Znudzon: I you say that i can write for example good,powerful physic simulator with OpenGL on racket ?
15:07 offby1: probably.
15:07 offby1: Dunno anything about OpenGL, so I can't comment.
15:08 Znudzon: It is propably but noone ,never write something big in this ?
15:11 (join) lucian
15:11 bremner: Znudzon: I've used both Oz and Racket, and racket is much more "serious"
15:12 bremner: all of the students I talked to much prefer it.
15:14 bremner: Znudzon: you can look at http://planet.racket-lang.org/  to see some things people wrote in racket
15:15 bremner: most of racket is written in racket, not sure if that counts.
15:24 Znudzon: http://shootout.alioth.debian.org/u32/benchmark.php?test=all&lang=racket&lang2=clojure    its quite fast.
15:24 rudybot: http://tinyurl.com/4432nwu
15:25 bremner: yeah, there is a pretty sophisticated JIT afaui
15:35 Znudzon: bremner: How racket can deal with many threads ?
15:35 bremner: Znudzon: I don't have experience.
15:38 offby1: I think it has its own pseudo-threads; I don't think it makes actual OS threads.
15:38 offby1: On the other hand, it can make subprocesses easily enough.
15:38 Znudzon: ok :) I think that I will write next poject in Racket(double-pendulum with interface) . Thank you for answers .
15:40 bremner: pseudo-threads are often better if you have many (10,000)
15:41 (quit) anRch: Quit: anRch
15:42 Znudzon: If i'll have many threads i was consider to use Erlang . Iheard that he good at this
15:43 offby1: it certainly is.
15:43 offby1: it's a somewhat lower-level language, though.
15:44 bremner: I'd guess erlang support for e.g. opengl would be dicey
15:44 offby1: If you want to have a lot of different machines collaborating, then Erlang is an excellent choice.  But for just one machine, it's probably not that great
15:44 offby1: bremner: yep
15:45 Znudzon: bremner: http://www.wings3d.com/ was written in Erlang
15:46 bremner: wow, neat.

19:59 offby1: damn, that looks pretty straightforward :-|
19:59 offby1: lemme see if it works for me
20:00 rekahsoft: offby1: i know eh...like port 3306 is open and mysqld is running properly (i can get ahold of it using "mysql -u user -p")
20:00 offby1: works, or at least, I get "access denied" rather than "Connection refused".
20:01 rekahsoft: as it should...what do you think is up?
20:01 offby1: you passed "-p" twice on your shell command line.
20:01 offby1: wonder if that's relevant.
20:02 rekahsoft: offby1: what? where?
20:02 offby1: <rekahsoft> but "mysql -p 3306 -p -u ..." works (the mysqld daemon is running and accecable)
20:02 offby1: I see two "-p"s there
20:04 rekahsoft: i meant "mysql --port 3306 -u user -p"
20:04 rekahsoft: my mistake
20:04 offby1: perhaps mysql is actually connecting to some box other than "localhost".
20:04 offby1: and it's running mysql, and localhost isn't.
20:05 offby1: simplest explanation I can think of.
20:05 rekahsoft: offby1: nope..i set up the mysql server..its running locally
20:05 rekahsoft: maybe a firewall issue?
20:05 rekahsoft: the port is open tho?
20:06 rekahsoft: using "iptables -A TCP -p tcp --dport 3306 -j ACCEPT"
20:06 offby1: can't imagine why the "mysql" command-line client would get a different result from racket; they're almost certainly doing the same thing under the covers.
20:07 offby1: might be time for "strace".

21:38 rekahsoft: offby1: work this time?
21:38 offby1: yeah
21:39 offby1: I think you're being burned by the traditional "the top level is hopeless" thing.
21:39 offby1: not sure, really, but that's my hunch.
21:39 offby1: Let's see if the magical genie known as "eli" is around.
21:39 offby1 clears throat
21:39 offby1: Eli, Eli, lama sabachthani
21:40 offby1: sometimes if you say that three times in the mirror, the Great Eli will appear.
21:40 offby1 drums fingers
21:40 offby1: maybe he went out for some KFC
21:40 offby1: anyway: things occasionally work differently in the top level than they do in modules.  Generally the module behavior is more "correct".
21:41 offby1: So you have to ignore that it worked at the repl, and whup the module to work.
21:41 offby1: most schemers would talk you out of using "eval" in the first place; typically, whatever you're using it for, there's a straightforward alternative.
21:42 offby1: Frankly I can never remember why 'eval' is a bad idea, but I know that I never feel the need to use it.
21:42 offby1: another option is to read its docs, and look at optional arguments; you might be able to pass it the current global namespace as an argument.
21:50 offby1: rekahsoft: I think this does what you want: http://ix.io/1Cy
21:50 offby1: you have to talk the "eval" into using the namespace you want.
21:55 eli: rekahsoft: You need a "#lang racket" at the top of the file, so it loads as a module.
21:55 eli: But then you'd obviously go into the problems that offby1 is probably talking about.
21:56 eli: offby1: (BTW, "lama sachtani" would be closer to having a meaning...)
21:57 offby1: ... if what?
21:57 offby1: oh, I just scraped it outta Google.
21:57 offby1: I didn't even know that was Hewbrew; I guess I assumed it was ... uh ... Aramaic?
21:58 offby1: alas, I think Mr Soft is no longer here.  Pity, because  I learned a little bit about namespaces on his account.
22:00 eli: This is strange, that that word is used like that.
22:00 eli: (In what some people call "a bible"...)
22:01 offby1: .oO("Hewbrew"?)
22:01 eli: The wikipedia page (http://en.wikipedia.org/wiki/Sayings_of_Jesus_on_the_cross) has some guesses about what the word could have been.
22:02 eli: The interesting thing is that the word I used ("forgotten me") is not any one of those guesses.
22:02 offby1: that's probably the one I was looking at.
22:03 eli: In any case, if you want to learn about namespaces and why `eval' gets broken when used in side a module: http://docs.racket-lang.org/guide/eval.html
22:03 offby1: oho
22:04 eli: λx→x²
22:05 eli: I just hacked my emacs to enter such things conveniently.
22:06 offby1: ha, that guide is exactly what the late rekahsoft wants.
22:06 offby1: And I'm pleased to see that I figured out the same solution that it recommends.
