Hello,
I am interested in exploring more in depth FRP. I had a look at the wiki
page and started to explore "reactive" which looked promising at first
glance and backed by quite a few articles and tutorials, but 1) it did not
install properly on my haskell platform and 2) from the mailing-list

How about recommending a Scala book instead of Java? That would teach a
functional mindset, and on stepping back to Java, they'd just have a
different syntax for types, and some missing stuff.
On the Java side, I own "A Little Java, a Few Patterns" by Friedmann and
Felleisen. This would certainly

Has anyone read the news at http://kennethreitz.com/xcode-gcc-and-homebrew.html?
It looks like Apple is going to support a minimalist command-line
based toolchain for Xcode called "Command Line Tools for Xcode" based
on the OSX-GCC-Installer project.
Would Haskell support this rather t

Hello,
I have been looking through Hackage database for a Haskell
implementation of a database(not a binding) but couldn't find anything.
Probably it was under my nose??

Two standard books are "Effective Java (EJ)" and "Java Concurrency in

Hi, cafe,
I find myself in the unusual position of having to recommend a few
books on Java to people who want to use it professionally. As the people
demanding this live in Burundi, I can't really say "Learn Haskell".
Odds are they won't find a job there if they don't use mainstream languages.

Sometimes we want to store very large collection types in RAM -- such as a
Data.Map or Data.IxSet.
It seems like we could trade-off some speed for space savings by
compressing the values in RAM.
Lemmih has previously created compact-map:

The desugaring is simpler with the current setup:

do { p <- e; STMTS }

It seems like it would still be useful for *optimizing* the implementation
of STM in Haskell; in particular, small transactions seem like a great way
to implement lock-free data structures by handling the non-composability of
compare-and-swap.
So while you wouldn't implement "atomically a" by "XBE

Since people are mentioning how great the Haskell type system is for
refactoring, here's one of those "wow, that's really great" experiences I
just had hacking on some Java code in Eclipse. I wanted to remove duplicate
code, so I selected one of the duplications and used Refactor->Extract
method.
Got this figured out, so I thought I'd update the list:
The problem was a call to `addFinalizer` on a `Socket` value, where
data Socket a = Socket {
_socket :: Ptr ()
, _sockLive :: IORef Bool
}
Under 7.4.1 with -threaded, the finalizer was being run prematurely. I'm
not clear on
Neat, thanks Johan! (I had no idea it was so easy to post to Reddit.)
I also put the proposed project on the trac:
http://hackage.haskell.org/trac/summer-of-code/ticket/1608
So feel free to contact me, interested students!
Cheers,

If we have separate directories, then you can "build-depends:
own-package". This means that on

Note that there's also support for ghc-mod using [syntastic][1] for
