Welcome to issue 211 of the HWN, a newsletter covering developments in the Haskell community. This release covers top stories found around the net between January 01 to 14, 2012.
This is going to be a shorted version, as I have been out of time. I did not want to let more time go by without a heartbeat from your friendly HWN.
Happy coding!
Quotes of the Week
- <ddarius> xtalmath: #math or #not-math would probably be a more appropriate place to ask.
<shachaf> ddarius: Those two channels pretty much cover it all.
<ddarius> shachaf: You're clearly not an intuitionist. - monochrom: in fact, freedom is the freedom to write 2.2 = 4
- Jafet: caleskell is the standard golf course.
- byorgey: Escaped skolem! Authorities mount massive search. News at 11.
- BMeph: loves swapping function arguments, he said flippantly
- kmc: "Haskell is great, because Curry-Howard! Proving things in the type system. We can prove that, uh, Ints exist, unless they're [bottom]."
- Jafet: In Soviet Russia, State executes you
- byorgey: that would be known as "low-dimensional linear algebra", where "low-dimensional" is said in as condescending a tone as possible
- monochrom: at a crossroad you meet an angel (always tells the truth) or demon (always lies). the crossroad gives you two choices of roads, one to heaven, one to hell, and only the angel or demon knows which is which. if you ask "how would you answer if I asked 'what is a monad?'", what will happen?
