Welcome to issue 158 of the HWN, a newsletter covering developments in
the [1]Haskell community in the week of October 31 - November 06.
I'd like to start things off with a quote from Jeremy O'Donoghue this
past week on a thread that produced plenty of laughs:
Haskell was developed by Isaac Newton in the 15th Century as a tool
to help his investigations into the Alchemic arts. It was
rediscovered in the 1980s by three Cambridge undergraduates who were
browsing through Newton's laboratory notebooks looking for smutty
jokes in the margins, and has since developed into an elaborate joke
perpetrated by elite computer scientists who believe that
predictable order of execution is contrary to natural law. The
current version of Haskell is Haskell 1714, which adds syntactic
sugar for Zygohistomorphic Premorphisms to the original language
definition of 1693.
This week we had 378 messages posted to Haskell-Cafe (up 76 from last
week!), 30 stories posted to Reddit (1 more than last week), 40
questions posted to StackOverflow (15 more than last week), and 96
updates to Hackage (11 more than last week). Busy busy week!
From all the noise in the intertubes, it sounds like BelHac was
awesome. There were plenty of kudos to Jasper Van der Jeugt for how
well things went. Jasper posted a [2]summary blog, and we also have
some [3]pictures from the event.
Announcements
Will Sonnex [4]updated Zeno, a fully automated inductive theorem
proving tool for Haskell programs.
Gregory D. Weber [5]updated Sifflet, a visual, functional programming
language and support system for students learning about recursion.
Mario BlaÅ¾eviÄ/= [6]updated monad-coroutine and SCC to version 0.6.
The monad-coroutine package exports a generic monad transformer:
Coroutine: Functor s => MonadTrans (Coroutine s).
Johan Tibell informed us that he has [7]merged network-bytestring into
the network package. This means that efficient and correct networking
using ByteString is available as part of the standard network package.
By far, the most popular thread this week in -cafe was a thread
entitled [8]"Haskell is a scripting language inspired by Python." As
you can imagine, many could not resist! The thread diverted into some
interesting historical notes about Haskell.

Quotes of the week
* Luke Palmer:Also they "don't scale well", which I guess means that
they don't make it inconvenient to design badly.
* merijn: <dankna> someday we'll need meta-software that converts
from obsolete languages into modern ones <merijn> Don't we call
that compilers?
* dolio: Let's spawn a thread every time we want to and two booleans.
* ray: how about a language where you program with unit vectors:
orientation oriented programming
* Axman6: Haskell is easy, you just apply functions to arguments, and
then you apply them to other arguments. Axman6's girlfriend: I
don't like conflict
* monochrom: in soviet haskell, functions run you
* geheimdienst: in soviet russia, i remember lambdabot's quotes
* Funktorsalat: sum is just the free monoid functor applied to the
mediating arrow of the terminality of ()
* geheimdienst: ah, yes. now we have to make a lambdacat captioned
"kittehs no bery gud at speling. we says leksah fur lexer and monad
fur moniod in catagory of ennobunktors"
* Vanadium: That tripped my C++ highlight.
* jmcarthur: what you just typed isn't even well typed
About the Haskell Weekly News
