Haskell

what is | in this code?

    class (Monad m) => MonadState s m | m -> s where
        get :: m s
        put :: s -> m ()

It is most likely an OR in one way or another... I'm afraid my grasp of the Haskell syntax is not that great, many things are still out of my reach.

By the way, I've always wondered what the forall thingy does in type signatures!

lolwut?

class Monad m => MonadState s m | m -> s where
 get :: m s
 put :: s -> m ()

modify :: MonadState s m => (s -> s) -> m ()

gets :: MonadState s m => (s -> a) -> m a

class Gonad m => GonadState s m | m -> s where
 get :: m s
 put :: s -> m ()

modify :: GonadState s m => (s -> s) -> m ()

gets :: GonadState s m => (s -> a) -> m a

Yeah, I'm fucking talking to you, /prog/ and all of you stupid asswipes who post here with your shitty wannabe elitist crap.

I run a Linux server.  I wanted it to handle my torrents instead of me.  I wanted to be able to access it via a web browser, and have it run constantly.  I did not want a gui at all.  There were not a lot of choices for me.  Basically btpd and Azureus.

After some consideration, and reading, I chose Azureus.  Never knew it had a console-only mode.  I installed it.  This necessitated me to install the Java runtime.  You guys have commented on various occasions about the slowness of Java and memory leaks.  So I was worried.

Well, assholes, the shit's been running for about two weeks (on my server which has an uptime of 43 days) and the performance of my server has not been impacted, even when it's handling three simultaneous torrents.  Nor is it a memory hog, and I don't notice an increase in it's memory footprint over time.

Azureus rocks.  Fuck off, you dumb motherfuckers.

Oh, and my server isn't a powerful machine.  500Mhz Celeron CPU with 256MB RAM running 2.6.19.

Again, fuck off.

In before flurry of memes, useless comments, faggotry, and Redcream flood.

DID ANYONE FIND OUT THE ANSWER PLZ???????????????????????????????

>>6
rtorrent or gtfo.
in before YHBT.

It is a haskell guard.

>>9
No it isn't.

>>10
what is it then?

>>6
HOLY SHIT THREE SIMULTANEOUS TORRENTS !!!  Too bad I can run 20 simultaneous torrents with rTorrent.

>>11
I don't know, some kind of OR.

>>13
Dont guess, we can all make stupid guesses

No, you.

>>15
faggot

>>16
Same person.

>>17
Pame serson.

>>9
Then what condition does it stand for?

Functional dependency.

>>20
Hm, I've heard of that... what is it :)?

fundeps

>>22
Thanks.

>>22
What's it do?

>>24
Something like this ...

... I don't quite get it, but I can at least categorize it in my head (the gay porn category, which is very large).

Don't change these.
