All you need to know about asynchronous exceptions is: *don't use
them!* They're
too difficult to reason about, in terms of failure modes and such. Use TVars
or MVars instead.

Just want to point out that this is actually surprisingly less of an impact
than I thought. As I did the step-by-step break down (you can see my blog
post), this one (changing `quotRem` to `quotInt#` and `remInt#`) yielded

Thanks for your input.
As stated by Ivan I was looking for a solution to use in a public blog
like wordpress.com.
I chose Chris Yuen solution with a minor revision because I use

Hi,
I released this library a while ago but didn't tell anyone, thought I would
let people know.
Would be cool to get feedback, suggestions etc.

PS: There are no recent commits since I'm going to be overhauling the
architecture once Snap 6 comes out
Hi Simon,
I found a bug in alex-3.0 and I'm attaching a fixed source file -
templates/wrappers.hs (modified against alex-3.0 from cabal unpack).
Explanation:
I was installing bytestring-lexing 0.2.1 and it failed to install with
alex 3.0, which was released on Aug 4.
It succeeded, however, with

I was recently reading "Asynchronous Exceptions as an Effect" by Harrison,
Allwein, Gill and Procter, and noticed at the end that they found an error

I didn't have any trouble building lambdabot when linking to readline built
through Homebrew. Currently using Lion, Xcode 4.1, and GHC 7.0.4.

No, GHC calls out to C for 64-bit integer ops on all 32-bit platforms.

You can probably just post your code as Gists in GitHub. They provide an
"embed" button to give you a
Hi all,
Thanks Bryan, reading your clean code was good for my Haskell health :)
I took your code and did some more research. I think I have found the
answer. I have written an extensive analysis in my blog post

Dear all,
I am using the library Text.XHtml.Strict.Formlets to build a validating
form. I use the function "file" to get a file upload widget. The
encoding is set to multipart. I want to check, if the user entered
something or left the widget empty. However, when entering nothing,

Hi, there is a conflict between ghc' libiconv and Ports installed libiconv.
make sure first sudo port deactivate -f libiconv
then install again, it should work.
however, it is very ugly since your other port installed libraries needs
libiconv, like gnuplot, so when you need port installed libico
Another alternative is to use the HsColour package:
