Hi Yuras,
thanks for the link. That's the sad truth. I don't know the actual
reasons, but suspect there are many. Overtime work, fatigue, greed and
alienation which are ubiquitous it today's society are among them. I
admire people who nevertheless manage to work on open source projects in

Fay tries to be very simple, the code base is small (~4800 LoC). This

Wow, great idea :) I'd like to participate. May I ask why don't you
schedule the event on weekend or on Friday at least?
Best wishes,

Second, all your examples so far used structural subtyping (objects
with the same fields have the same type) rather than nominal
subtyping of C++ (distinct classes have distinct types even if they
have the same fields; the subtyping must be declared in the class
declaration). For the structural

I've been experimenting with emulating subtyping and heterogeneous

objects of a class hierarchy in C++ program.
So far I implemented upcasting using a chain of type classes and now I'm

I've written a snippet which generates a file full of random strings.
When compiled with -O2 on ghc-7.6, the generation speed is about 2Mb per

rather disappointing. Maybe I've missed something trivial? Any

Recently I've revived my old toy project. It's a sound spectrum analyzer
with Gtk2hs interface. I decided to rewrite it into a pitch tuner.
Basically I'm done, but I've ran into performance difficulties while

Hi, everyone!
I have a function, which sometimes takes a long time to compute or even
may loop forever. So I want to limit it in time somehow.
I tried to run it in another thread in order to kill it after its time
lapsed. But it seems to lock out other threads so they can't terminate it.

Hello, all.
I'm experimenting with concurrent haskell using GHC 6.4.
I wrote these fuctions as described in Tackling the Awkward Squad:
par_io :: IO a - IO a - IO a
par_io t1 t2 = do c - newEmptyMVar :: IO (MVar a)
id1 - forkIO $ wrapper c t1

Hello everybody.
I have a long list consisted of a small number (about a dozen) of
elements repeating in random pattern. I know all the possible elements.
I need to count number of occurences of each particular element and to
do i quickly.
For example
quick_func Eq a = [a] - [(a,Int)]

I'd use a Map in GHC 6.4:
count xs = toList $ fromListWith (+) (zip xs (repeat 1))
or a FiniteMap in earlier versions:
count xs = fmToList $ addListToFM_C (+) emptyFM (zip xs (repeat 1))
both of these seem to be quite fast.
