Haskell Weekly News
Issue 83 - August 30, 2008
Welcome to issue 83 of HWN, a newsletter covering developments in the
This is the "better late than never" edition. As an excuse I could tell
you that my home internet service has been horrible (now fixed) and I
was away from home for a few days with my wife celebrating our third
wedding anniversary. But instead, I give you a link to the
Uncyclopedia entry on Haskell. If you haven't already seen it, you
should give it a read, being sure not to drink any milk at the same
time, or at least pointing your nose away from the keyboard if you
insist on drinking milk.
If Dell sends John Goerzen (CosmicRay) one more catalog, it will
actually be a federal crime.
LogFloat 0.9. wren ng thornton announced a new official release of
the logfloat package for manipulating log-domain floating numbers.
This release is mainly for those who are playing with Transfinite
rather than LogFloat, but the interface changes warrant a minor version
validating xml lib - need some guidance. Marc Weber asked for help
developing an xml generating library validating the result against a
gsl-random 0.1 and monte-carlo-0.1. Patrick Perry announced that he
has started on bindings for the random number generators and random
distributions provided by the gsl. He has also written a monad and
transformer for doing monte carlo computations that uses gsl-random
internally. For a quick tutorial in the latter package, see his
Wired 0.1.1. Emil Axelsson announced the first release of the
hardware description library Wired. Wired can be seen as an
extension to Lava that targets (not exclusively) semi-custom VLSI
design. A particular aim of Wired is to give the designer more control
over the routing wires' effects on performance.
darcs weekly news #1. Eric Kow sent out the first edition of the
new Darcs Weekly News!
zip-archive 0.0. John MacFarlane announced the release of the
zip-archive library for dealing with zip archives.
The Monad.Reader - Issue 11. Wouter Swierstra announced a new issue
of The Monad.Reader, with articles by David Place, Kenn Knowles,
and Doug Auclair.
First Monad Tutorial of the Season. Hans van Thiel announced a new
monad tutorial, The Greenhorn's Guide to becoming a Monad Cowboy.
"Real World Haskell" hits a milestone. Bryan O'Sullivan proudly
announced that the draft manuscript of Real World Haskell is
complete! It is now available online in its entirety. The authors
expect the final book to be published around the beginning of November,
and to weigh in at about 700 pages.
Mueval 0.5.1, 0.6, 0.6.1, 0.6.2, 0.6.3, 0.6.4. Gwern Branwen
announced a number of new releases of Mueval. Lambdabot now
uses mueval for all its dynamic Haskell evaluation needs.
Hoogle Database Generation. Neil Mitchell (ndm) announced that a
new release of the Hoogle command line is out, including bug fixes
and additional features. Upgrading is recommended.Two interesting
features of Hoogle 4 are working with multiple function databases (from
multiple packages), and running your own web server.
Haskell news from the blogosphere.

Simon Peyton Jones.
* Neil Mitchell: Running your own Hoogle on a Web Server.
* Braden Shepherdson: Announcing xmonad-light. Braden is rolling
out a new configuration framework for xmonad, providing an easier
learning curve for those not wanting to learn Haskell right away,
and an easy transition to a more powerful Haskell configuration
when they want it.
* Gabor Grief: Category. Gabor is excited that base-3.0 will
* Douglas M. Auclair (geophf): Ten = 1+2+3+4. Solving an
arithmetic puzzle with Haskell, Prolog-style.
* Paul R Brown: perpubplat now on github.
* Douglas M. Auclair (geophf): "Lucky you!"?. Doug shares some
secrets of his success in getting Haskell/Dylan/Mercury/Prolog
* Neil Mitchell: Hoogle Database Generation. Neil releases a new
command-line version of Hoogle, including bug fixes and additional
features -- multiple function databases and the ability to run your
own Hoogle server.
* Patrick Perry: A Monte Carlo Monad for Haskell.
* Mads Lindstroem: Proposal: Adding composability to WxHaskell.

* >>> Hans van Thiel: The Greenhorn's Guide to becoming a Monad

dividend that pays during your imperative-programming day job.
* Jason Dagit: Darcs 2 Real-World Push Performance Evaluation.
* Well-Typed.Com: What's wrong with make?. A lot, apparently:
it's too static, and makes it easy to write incorrect rules. Duncan
(dcoutts) provides an analysis.
* Dougal Stanton: Lord of the Flies as a window onto monadic IO.
* Real-World Haskell: A tighter page count estimate. Real World
Haskell is going to be about 700 pages!?

Quotes of the Week
* shepheb: #haskell isn't so much on-topic when discussing Haskell,
* chrisdone: it's neat how you learn haskell because you are drawn in
by the purely functional paradigm, and then you find loads more
things like algebraic data types, monad abstractions, arrows and
applicative, lack of objects... so that when people say "well, it's
not haskell, but at least X is functional", it's just not the same
* lambdabot: [tristes_tigres] @vixen unsafe [lambdabot] you're
turning me on :)
* b\6: sometimes i make variables f and ck and find some reason to
multiply them like f*ck if i'm having a bad day.
* waynemokane: wow... thanks everyone - it looks like I have a full
day of reading type signatures ahead of me.
* mauke: call/cthulhu
* seydar: monads are just like saran wrap.
* b\6: keep this info private, but you can actually overclock your
brain. the technique i use is to loop mplayer playing oggs but
increase the speed like -speed 1.25 for 125% normal. your brain's
speed increases accordingly, allowing you to solve problems much
