This is a post about re-designing the whole Haskell web site.
We got a new logo but didn't really take it any further. For a while there's
been talk about a new design for the Haskell web site, and there are loads
of web pages about Haskell that don't follow a theme consistent with
Haskell.org's,
Fran Allen talked about this in Coders at Work (I typed this up quickly so
forgive typos):
Allen: Recently I realized what was probably the root cause of this:
computer science had emerged between 1960 and 1970. And it mostly came out
of the engineering schools; some of it came from mathematics.

Wouldn't it be great if pattern variables could be used more than once
in a pattern? Like so:
foo [x,x,_,x] = "The values are the same!"
foo _ = "They're not the same!"
where this could be rewritten to:
foo [x,y,_,z] | x == y && x == z = "The values are the same!"
foo _
#x27; matches X is
Predicate A.
Likewise, for
foo (x,x) = ...
We can use Predicate A to compare `a' and `b', for determining whether the
(x,x) pattern succeeds.

Hi,
I thought I'd go through my uploaded Hackage packages and decide which
ones I am going to maintain, which are worth others maintaining, and
which are probably not worth maintaining (spoiler, most aren't).
1. Interested in and will continue maintaining:
gd, higherorder, cgi-utils, fastcgi, irc
I've never used the cairo library as it was part of gtk2hs and thus
not on Hackage. Looks like it's on Hackage now as of last may. I'll
take a look next time I want to do graphics. I imagine it's faster.

Does Cabal have a way to produce binary distributions from a package?
I need to create a binary distribution of my project which does not
depend on GHC or any development tools. The package should include all
required data files and configuration files. I've got the latter
covered with Data-Files
Check out the userHooks in Cabal[1]. I believe you can use, e.g.
hookedPreProcessors[2], or preBuild to preprocess your files into
regular Haskell files before building takes place.

Hey autopackage looks swish! WiX also looks like a nice, more native
solution for Windows. Cheers!

I don't know about doing it at the server side.
I've been trying to setup the right filters and quick links in my
GMail to filter out emails I'm not interested. I'd like to recieve
*all* emails, but be able to filter out the ones I'm not interested in
so I never see them again.
I tried an Uninter

OpenID sounds like a plan. I'll probably add OpenID support to
hpaste.org for management over pastes/remembering user details/default
language, tracking annotations of your pastes, etc. We already have an
OpenID Haskell implementation. Programming sites are already using it
(Google, StackOverflow),
FWIW we're still looking for web programming Haskellers at CREATE-NET!

Suppose I have a data type:
data A f = A { a :: f Integer }
why can't I derive a Typeable instance like so?
deriving instance Typeable (A Maybe)
I get:
Can't make a derived instance of `Typeable (A Maybe)':
`A' has arguments of kind other than `*'
In the stand-alone deriving inst
Just for what it's worth, the following does work:
newtype AMaybe = AMaybe { unMaybe :: A Maybe }
deriving instance Typeable AMaybe
Which leads me to be kind of baffled by the above error message.

Actually I suppose the newtype one makes sense because it's opaque and
not paramerized so it doesn't inspect the unMaybe. I'll think about
this some more.
