This week is an experiment, I'm eliminating the mail client from the sendout,
and simply using sendmail directly. If this doesn't fix the line ending problem,
then I'm pretty sure it's a software issue, and not a client issue. If you
notice problems, please email me at this address, put [HWN] in the subject
line so my filters will catch it. Please _don't_ email me if there are no
Haskell Weekly News
Issue 133 - September 26, 2009
Welcome to issue 133 of HWN, a newsletter covering developments in the
This week, we have a few new libraries, some interesting discussion
about EDSLs, a comment from Oleg, and dons extolling the virtues of
SCIENCE! On the new HWN software front, I've decided to jump right into
something I had planned for far further down the development chain.
Specifically, rather than scraping GMane for messages, I've been
working on a way to grab the messages directly from the mailing-lists.
I'm not entirely sure how I'm going to create links as they are now for
the messages, but one crisis at a time. Till next week, here's the
Haskell Weekly News!
epoll bindings 0.2. Toralf Wittner announced the release of epoll
bindings 0.2 available here. Epoll is an I/O event notification
facility for Linux similar to poll but with good scaling
characteristics. This release adds a buffer abstraction on top of the
existing low-level bindings, so client code can write and read to
buffers without having to deal directly with the underlying epoll event
diagrams 0.2.1, and planned major improvements. Brent Yorgey
announced version 0.2.1 of the diagrams library, available now on
Hackage. This minor release which fixes a few bugs and adds a few
new combinators, most notably a grid layout combinator contributed by
Workflow-0.5.5, TCache-0.6.4 RefSerialize-0.2.4. Alberto G. Corona
announced Workflow 0.5.5. Workflow provides a monad transformer that
encapsulates any monad in a state monad that bring automatic state
logging and recovery. A workflow can be viewed as a thread that persist
across planeed or unplanned application shutdowns. When recovering the
execution is resumed at the last action that was logged. The process
continues at the same state as if not interruption took place.
graphviz-29126.96.36.199. Ivan Lazar Miljenovic announced version
29188.8.131.52 of the graphviz library. This is another bug-fix release,
fixing the problem spotted by Kathleen Fisher where Dot keywords need
to be explicitly quoted if used as labels, etc. There is no change to
histogram-fill, library for creating histograms. Khudyakov Alexey
announced histogram-fill. histogram-fill provides a generic and
convenient API for making histograms. Features include, multiple
simultaneous histogram creation, Immutable histograms, and
Serialization to and from human readable text.
Darcs Hacking Sprint - 14-15 November Vienna. Eric Kow announced
the third Darcs Hacking Sprint. Which will take place 14-15 November,
2009 at the University of Technology, Vienna, Austria. Anybody who
wants to hack on Darcs (or Camp, Focal, SO6, etc) -- Beginners
especially -- are welcome!
2nd CFP: TLDI 2010. Andrew Kennedy announced a second call for
papers for TLDI2010, the Types in Language Design and Implementation
darcs 2.3.1: better docs, fewer bugs. Reinier Lamers announced a
new stable version of darcs, with bugfixes from 2.3.0, improved
documentation, and removal of the old autoconf build system.
TFM09: Call for Participation (FMWeek, Eindhoven, November 2009). J.N.
Oliveira announced a Call for Participation in TFM2009 2nd Int. FME
Conference on Teaching Formal Methods Friday, November 6th 2009,
co-located with FM2009 : 16th Int. Symposium on Formal Methods
Eindhoven, the Netherlands, November 2 - November 6, 2009.
Monad Tutorial in C++. Adrian May wrote a tutorial about monads in
some other niche language...
Beginning of a meta-Haskell. Oleg -- as if he needs any
introduction -- commented on things far above my ability to understand.
Evidently, however, it involves extensible, modular interpreters in the
``tagless final'' style. It was a reply to an earlier thread here.
An issue with EDSLs in the ``finally tagless'' tradition. Brad Larsen
talked about his run in with the expression problem while
experimenting with EDSLs.

Quotes of the Week
* lilac: ponders whether unsafePerformIO would be better as
* bos: [On the type signature of hPrintf] This makes me a sad Irish
* ksf: (But if (on the other hand)) (I think only a number in general
(whether it be five or a hundred)) (this thought is rather the
representation of a method (whereby a multiplicity (for instance a
thousand) may be represented (in an image in conformity with a
certain concept)) than the image itself.
* dons: ah, via the magic of SCIENCE
* dobblego: many of my colleagues used to be [fond of ruby] as well
until I was let loose on them
* dons: (on whether a library is wanted) *yes* put it on Hackage!
* BMeph: (about parsec) 'Cause it's light-years ahead of the
* switch: Comeon people! You make the news!
* ray: I think programmers make the worst programmers, also the worst
people, and I'm saying this having not looked at programming reddit
in a while.
* Orclev: ... a lot of haskell still looks greek to me, and I'm not
talking about lambdas.

for Cabal packages. Let's call them cabbages." [see
* Reinier Lamers: If we keep up the current pace of performance
hacking, darcs will be complete before you even hit the enter key
in a few years
* Trent Buck: [To Reiner Lamers] With the appropriate (ie unbuffered)
terminal, this is already the case for interactive prompts.

too many opening) parentheses (although it was still funny (even
though it could have been edited (to make the parentheses match (even
though that is not an important issue)))).
