Quotes of the Week

* nand': haskell has a few advantages in the industry that few other

languages can offer. these will become more obvious as time goes on

and programming is forced into a functional direction in general.

* seo: What i do not realize is actually how you are now not really

much more well-liked than you might be right now. You are so

intelligent. You realize thus significantly in terms of this

subject, produced me in my view consider it from so many numerous

angles. Its like men and women are not interested unless it‚s one

thing to do with Woman gaga! Your personal stuffs excellent. Always

care for it up!

* monochrom: Schrodinger's Klein glass bottle: before you look, the

cat is inside or outside; after you look, it is inside and outside

* cmccann: Ruby is a fine language if you're secretly a lisp

programmer but want to hide behing perl and smalltalk so nobody

catches you

* mlh: nice quote -- quick, someone register it for posterity

* something: somebody never said, naturally.

* irene-knapp: I was going to take a famous quote and put it in

lambdabot as my own but I couldn't decide on one

* shachaf: getLine :: IO String contains a String in the same way

that /bin/ls contains a list of files

* edwardk: [unsafePerformIO] sounds like a good idea, its tempting,

it makes life easy, for the first 2 lines of code. then you go to

write the third and everything goes to shit

* cmccann: Idiom brackets are where you consume a mixture of alcohol

and Conor McBride papers until your vision gets blurry enough that

you can't actually see the Applicative operators anymore.

* Philippa: incidentally, if you think about this you're probably

starting to image control flow that looks like it's a glyph for

summoning cthulhu - and then realising that it's 3d and consists of

'towers'. Make sense?

* c_wraith: also, "actual" reals is a funny thing to call a set that

consists mostly of things that cannot be described.

* NihilistDandy: I feel like a hipster whenever I talk programming

with people at my school. I always have to preface discussions with

"you've probably never heard of it" :/

* ion: Three lefts make two wrongs

* elliott: Explicit recursion should generally be avoided. Also,

general recursion should be explicitly avoided!

* CodeWeaverX: I expect that Weird Untraceable Suitcases Full Of Bad

could result from the program assuming such an operation is pure

when it clearly isn't.

* elliott: cmccann: the instances list haddock generates is now a

thing of majesty

edwardk: elliott: welcome to my world

* mzero: functional programming has a property that is often lacking

in other languages... at dinner last night we were discussing it,

and I dubbed it: "The Princess Bride" property --- which is, that a

piece of code means what you think it means

* sclv: You have a problem and think "I'll use a hash function." Now

you have intermittantly colliding problems.

* monochrom: data Ph a = Ph -- the phantom monad

ksion: Is that a new Star Wars prequel? ;)

* user1151874: i already declare hp as int with value 3 now my

problem is when i put "hp--", it shows error [...] but if i put

"--hp", the result print is 3 not 2.

* edwardk: thats my secret. really i don't write anything. i just let

others do the work and upload it to hackage behind their backs
