Welcome to issue 165 of the HWN, a newsletter covering developments in

the [1]Haskell community. This release covers the week of January 9 to

15, 2011.

Announcements

Brent Yorgey [2]announced the release of issue 17 of The Monad.Reader,

containing the following three articles: List Leads Off with the Letter

Lambda by Douglas M. Auclair, The InterleaveT Abstraction: Alternative

with Flexible Ordering by Neil Brown, and The Reader Monad and

Abstraction Elimination by Petr Pudlak.

Andy Stewart [3]sent an invite to anyone interested in joining the

Manatee team. Manatee is a Haskell integrated environment written in

Haskell. Follow the link to see some videos posted for a better idea of

what the tool is.

Niklas Broberg [4]announced the release of version 1.10.1 of

haskell-src-extensions.

Huibiao Zhu [5]sent a call for papers to the 13th International

Conference on Formal Engineering Methods to be held in Durham, UK on

October 25-28 2011.

Read on to see what was hot in the Haskell community around the net...

Quotes of the Week

* ion: ddarius: Yeah, abstract concepts absolutely hate being

anthropomorphized.

* gwern: there are no beginnings or ends to the circular list; but a

cons cell thunked in Amador...

* tac-tics: If you wish to create the universe from scratch, you must

first invent the continuation.

* sproingie: hm. Ā i can't remember how to use @remember

* NOTE: Just say @remember :) I'm grepping the logs to find these

things

* Kaidelong: <Kaidelong> take 6 "bananas" <lambdabot> "banana"

<Kaidelong> clearly lambdabot is keeping the bananas to itself and

lying about it

* hpc: functor and applicative are easy, since you can remember them

as "those things what look like function application, sort of"
