Hi all,
Users of GHC on PowerPC would probably be aware of this bug:
http://hackage.haskell.org/trac/ghc/ticket/2972
which causes GHCi to segfault as soon as it was started.
Ben M. Collins has come up with a fix for this I am preparing it
for submission to the GHC git tree. I have have test
Kind Sirs/Madams,
Thanks in advance for your patience; the solution will no doubt be obvious to
those with greater experience than me. I have formulated a monad to provide
limited backtracking for implementing a rewrite system. The success case works
fine, but my intention is that on failure th
Hi,
I work developing multi-platform applications in Haskell. This poses
the following problem: I cannot compile binaries for windows from
linux (AFAIK). I "solved" this problem with the following
sledgehammer: I installed windows in a VM, I installed GHC, I
installed all the C/C++ headers & bina
he recent discussion of whether storablevector should be deprecated in
favor of vector reminded me: vector supports storable arrays, but it
doesn't support lazy arrays. While storablevector has lazy arrays and
a builder, it doesn't support boxed types (it would be become misnamed
if it did!).
So
We use Jenkins to build our applications. You can have Jenkins slaves
for different platforms. We also use cabal-dev to sandbox the builds,
separating the environments for different executables. This solution
does require one server for every OS you develop for, but I guess you
need that anyway, fo
Today I have observed that hackage.haskell.org/ timeout twice (in the
noon and in the evening.)
What is the problem? Is it that haskell users have increased so that
haskell.org is overloaded? That's very good news.
I am eager to donate some money if it requires server reinforcement.
Sincerely,

Yes, I would like to add a lazy storable vector to
vector-bytestrin

If you load this function in ghci, it behaves absolutely the same way.
How can I create OpenGL window in GLFW-b in ghci?

tl;dr: Is there any way to pass the Supercombinator level names (the
names in haskell source codes with zero indent) as context to a Monad
so that it will read from "The" context?

Hello
Is there some kind of nagios or similar monitoring software in place? In my
experience that really helps
when you don't have time to check the servers all the time, especially
since it is easy to write
small custom plugins for additional checks (e.g. on some of our work

I don't know about the current arc
Tillmann Rendel has correctly noted that the source of the problem is
the correlation among the random variables. Specifically, our
measurement of Sun's mass and of Mars mass used the same rather than
independently drawn samples of the Earth mass. Sharing (which
