Eric Y. Know released the 5th edition of the Parallel Haskell
Digest.

New and Updated Projects
* swapper (New - Roman Smrz) Provides a wrapper for functors,
which allows their data to be automatically and transparently
swapped to disk and loaded back when necessary.
[2] http://goo.gl/CwojE
* GA (New - Kenneth Hoste) Provides support for working with
genetic algorithms in Haskell.
[3] http://goo.gl/XjvFA
* hledger[-web] (Update - Simon Michael) Bugfix update.
[4] http://goo.gl/98ApM
* bindings-DSL (Update - Mauricio CA) Provides a language to
describe foreign interfaces on top of hsc2hs.
[5] http://goo.gl/fFL4Y
* hspec (Update - Trystan Spangler) This latest release includes a
command line runner that can search through directory trees for
specs and support for nested specs.
[6] http://goo.gl/rVbF0
* EclipseFP (Update - JP Moresmau) New features and bugfixes.
[7] http://goo.gl/dXS6t
Quotes of the Week
* dankna: I do [gui on osx] by writing a polyglot ObjC/Haskell
program
* maurer: I'd do it kmc style
* hpc: your next challenge: write a definition of fix in java that
fits in a twitter post
* kmc: i leave for 3 seconds and you're all metaprogramming and shit
* acowley: Haskellers are so abstract they can't even spell primitive
* edwardk: i was happy that i had the 4th entry on google for a
topic... but then i realized it was only for me, not for everyone
that searches for it
* kmc: oh, my suggestion was to hand off the fd's directly through a
UNIX socket ... but that's probably silly ... i just like the fact
that fd's can be passed through a unix socket
* monochrom: "linear types change the world!" says Wadler. "Record
updates change the type!" says Haskell. :)
* gosu: Type parameters are covariant. This is not sound, and that
does not matter.
* Yitzchak Gale: I certainly wouldn't dream of dragging in type-level
olegery, unsafe coercion, implicit parameters and other
experimental extensions. Simplicity just works.
