Welcome to issue 61 of HWN, a weekly newsletter coverin
I've created a new wiki page documenting all the new user groups for
Haskell that are springing up!

If you're starting a new group, please add it here, and publicise.

P.S. Some obvious user group candidates, in my opinion, would be a

Hi Dan,
Don't forget the 2nd law of thermodynamics: no 4-line file will stay 4
lines long after repeated code iterations. You might as well plan for
the inevitable.
If this library is for the extra interactions available when using a
libary with 2 classes (thats all BinaryDefer is likely to ev
Taking a lesson from relational databases, I'd put it in 5-normal form:
a separate module importing its two dependencies.

I've had a similar question, which I think boiled down to a
compilation issue. Consider packages A and B that can be defined
independently. But, just as Neil pointed out, perhaps A and B could
also interact beyond their basic definition.
My naive idea is that A would compile the simple independen
Hi
I currently maintain two libraries, TagSoup which defines the Tag data
type, and BinaryDefer, which defines the BinaryDefer class. If I
wanted to include an instance for BinaryDefer Tag, where would I put
it?
Putting it in either library introduces an artificial dependency on
the other. Putti
I am delighted to announce the first meeting of the London Haskell
User Group on Wednesday 23rd May from 6:30PM. The meeting will be
held at City University's main campus in central London, and Simon
Peyton Jones will be coming to give a talk.

HAppS LLC has part-time and full-time positions open for haskell programmers to:
* improve the open source haskell codebase at HAppS.org
* implement infrastructure to make it work well in Amazon S3/EC2 environments

The biggest advantage of Haskell to me is that it helps me write
better programs in other languages.
For one reason or another Haskell never turns out to be my final
implementation language my my programs gain in the process.

Hello haskell-cafe,
In System.Time,
data ClockTime = TOD Integer Integer
, where the first integer represents the number of seconds since epoch,
and the other represents the number of picoseconds. Is there a way of
retrieving the first part? (In Haskell 98, the ClockTime type is abstract).
I suspect this may be because gcc has managed to pick up the Cygwin ld instead of the mingw one.
Monique - what exactly is your PATH? What happens when you say 'ld --version'?
'ld --version' doesn't show differences between mingw/cygwin, does it?

Hi
Does cpphs allow me to include a whole file into a Haskell source
file, inserting automatically the string gaps?
No, but Hugs does with "Here documents".

Hi
How does
test = putStr "I\n\
\need\n\
\multiline\n\
\string\n\
\literals\n"
look?
Like the cpp will choke and die :) Multiline string literals were one
of the motivations for cpphs.

Hello,
Just for fun I'm trying to define multi line string literals. I have
the following code and I'm wondering if it can be improved
(understandability, elegance, performance): http://hpaste.org/1582
(look at the second annotation)
