Welcome to issue 273 of the HWN, an issue covering crowd-sourced bits

of information about Haskell from around the web. This issue covers the

week of June 30 to July 13, 2013.

Quotes of the Week

* monochrom: 8-bit word uses less memory, but if it doesn't have to

preserve information, I know how to use 0 bits of memory.

* byorgey: you know, servers migrate in the summer to their ancestral

breeding grounds

* emeijer: It must me said on the other hand compiler writers seem to

ignore the existence of formal semantics completely, probably

because they don't like greek letters.

* byorgey: now we have the pig operator <^(++)^> as well as the robot

monkey operator (:[])

* chrisdone: i remember when the internet was black and white and you

had to upload web pages back onto the internet when you were done

with them

* raganwald: Immuteability: The property of functional programmers

that prevents them from shutting up about pure functional

programming.
