[Haskell-cafe] Haskell Weekly News: Issue 279

[Daniel Santa Cruz]

Welcome to issue 279 of the HWN, an issue covering crowd-sourced bits
of information about Haskell from around the web. This issue covers the
week of August 25 to September 7, 2013.

Quotes of the Week

   * dmwit: I typically figure a parse error on line 500 means I have
 500 lines to inspect.

   * bos: bah, all you category wonks spoil the atmosphere. we were
 simple peasants, and proud, once.

   * merijn: edwardk's delegation has reached the point where he can
 have the language implementor explain his libraries...

   * ReinH: haasn asks an offhand question. edwardk wrote a thesis on
 it.

   * JaffaCake: children are automatically killed if their parents die
 for any reason

   * geekosaur: if the platform is batteries included, lens is a full
 fledged transformer robot included :)

   * FreeFull: Mathematical laws are so much nicer than legal laws

   * twey: to edwardk, v. to be working on a larger problem and
 absent-mindedly spin out a package to satisfy dependencies,
 accidentally solving the problem more elegantly than existing
 solutions (but perhaps incomprehensibly to anyone who can't dualize
 in their head)

   * elliott: lens is the DLC expansion pack for Haskell

   * monochrom: new catchy thing to say: an IORef Int contains an Int in
 the same sense as an IO Int contains an Int

[Daniel Santa Cruz]

Welcome to issue 271 of the HWN, an issue covering crowd-sourced bits
of information about Haskell from around the web. This issue covers the
week of June 9 to 11, 2013.

Quotes of the Week

   * cmccann: also please note that malign remains one of my best
 function names ever

   * dolio: Peak file descriptors is a myth.

   * mami: i think my brain rewired for higher typesystem compatibility

[Haskell-cafe] Haskell Weekly News: Issue 268

[Daniel Santa Cruz]

Welcome to issue 268 of the HWN, an issue covering crowd-sourced bits
of information about Haskell from around the web. This issue covers the
week of May 12 to 25, 2013.

Quotes of the Week

   * tikhonjelvis: the lesson is that the fix function exists to fix
 any type problems you may encounter

   * shachaf: The trouble with peano arithmetic is that it stops at 88.

   * Peaker: Python's dynamic nature adds slowness and unsafety, but
 doesn't actually make things more expressive

   * sj4nz: Programming in weakly-typed languages forever after will
 feel like working with punch cards. Send in your program to the
 nodejs interpreter and hope for a result to come back.

   * xplat: if you want to carry your machete all the time and not make
 people nervous, you need to constantly blaze trails

   * otters: heh, F# is just the unboxed version of F

   * quchen: This was the first time in months that I thought
 imperatively. Conclusion: 1. it complicated things, 2. it was
 refreshing

   * cmccann: I still kind of expect that the next standard will be
 haskell2017 or something, and all it will do is a minor change to
 lexical syntax of comments that fixes nothing but nevertheless
 breaks 20% of hackage.

   * cmccann: [on reimplementing cryptography in pure Haskell] writing
 in Haskell lets you use type safety to ensure that all the security
 holes you create are subtle instead of obvious.

Quotes of the Week

   * ciaranm: a category is just a category in the category of
 categories

   * cmccann: the Either monad is like the Maybe monad, except with
 something instead of Nothing.

   * sclv: Q: Why are the adjunctions of Galois connections backwards?
 A: He never got the hang of duals.

   * acowley: blackdog's experience with IDEs is apparently both more
 sensual and more culinary than mine

   * cmccann: shachaf jokes are what the quotes section of HWN is for.
 cmccann: though lately there have been not as many :[
 shachaf: cmccann: Hey, there wasn't a single shachaf quote in the
 last HWN!
 shachaf: Leave me alone.
 shachaf: There were two cmccann quotes.

   * edwardk: cmccann: i'm NDA'd out of that space for a while ;)
 elliott: edwardk just collects NDAs so that he can focus.

   * trapdInIO: in java everything happens elsewhere

   * edwardk: i never bothered to release the c preprocessor because it
 was entangled with an old compiler of mind

   * acowley: I get nervous when I haven't triggered the impossible for
 more than a month or so :/

   * hpc: be careful, excessive consumption of lenses will go straight
 to your type signature

   * acowley: The longer I leave this function named jumanji the less
 I want to find a better name

   * ion: The next step is unsafeCoerce. At that point youâre halfway
 into implementing lens.

   * bos: i'm not sure edwardk is a good model to follow. (a) because
 you won't be able to, and (b) because you won't be able to.

 maximum number of type parameters to a type constructor.
   * tac: It's actually really easy to remember all the numeric
 typeclasses in Haskell. Just think about what makes sense... then
 make sure whatever your answer is is not that

[Haskell-cafe] Haskell Weekly News: Issue 257

[Daniel Santa Cruz]

Welcome to issue 257 of the HWN, an issue covering crowd-sourced bits
of information about Haskell from around the web. This issue covers the
week of January 27 to February 02, 2013.

Quotes of the Week

   * shachaf: Everyone forgets about Agda Lovelace, the first
 constructivist.

   * applicative: I have my new ghc and am reinstalling my feeble world

   * wuttf: My world is starting to feel like isToyLanguage x = x /=
 Haskell

   * PenguinOfDoom: Being enlightened gentlemen, we split all
 programming languages into two groups, sucks and doesn't-suck and
 put all of them into the first group.

   * Taneb: lens has got to be the only library with more contributors
 than people who know how it works

   * shachaf: I like to put all my application's modules under GHC.*
 That's because I use the GHC API, and I want them not to conflict.

[Haskell-cafe] Haskell Weekly News: Issue 255

[Daniel Santa Cruz]

Welcome to issue 255 of the HWN, an issue covering crowd-sourced bits
of information about Haskell from around the web. This issue covers the
weeks of January 06 to 19, 201.

Quotes of the Week

   * ky3: Indexed monads are just categories in the category of
 endofunctors, what's the problem?

   * tac: I guess I'm just living in a fantasy world where the docs tell
 you how to use such a basic API :P

   * shachaf: 3.0 is an edwardk phase, not just a version number. It's
 like Picasso's Blue Period.

   * cmccann: Clearly the reason why edwardk uses Haskell now is because
 every C++ compiler has a restraining order against him.

   * shachaf: I'm not sure what your question is, but maybe lens is the
 answer.

   * cmccann: * cmccann has concluded that lenses are just a category
 whose objects are english prepositions and whose morphisms are all
 unsafeCoerce

   * shachaf: Some people, when asking about a problem in #haskell, get
 a link to okmij.org. Now they have two problems.

   * quicksilver: It returns undefined for convenience. I'm not really
 sure it's that convenient, but that's why.

   * edwardk: cmccann: let me get this straight you are saying that
 someone [mm_freak] who by their very nick admits to being a freak
 did something freakish?

[Haskell-cafe] Haskell Weekly News: Issue 254

[Daniel Santa Cruz]

Welcome to issue 254 of the HWN, an issue covering crowd-sourced bits
of information about Haskell from around the web. This issue covers the
week of December 02, 2012 to January 05, 2013.

As some of you might have noticed, there has been an interruption in
the scheduled transmission of the newsletter. I have, over the past few
weeks, completed a move to NYC! It has been wonderful to meet many in
the community at the Haskell NYC meetups. Here is to a great year for
our cherised community.

Let's get things started out the right way, with a litte Lambda
Style :-)
[1] http://goo.gl/nQYdp

Quotes of the Week

   * GuySteele: Some people prefer not to commingle the functional,
 lambda-calculus part of a language with the parts that do side
 effects. It seems they believe in the separation of Church and
 state.

   * edwardk: type level ieee floats are a crime against nature. i had
 to implement them in c++ for template meta programming once. never
 ever again

   * acowley: (regarding Proxy) Haven't you ever wanted to put something
 in a box and never think about it?
 elliott: children

   * merijn: xenocons: I spend the entire week grading FP homework, I
think it's impossible for you to surprise me :p
 merijn: That's confusing :

   * andr00: Today's software engineering word is farpotshket. This is
 a Yiddish word meaning, broken, because someone tried to fix it.

   * dmwit: I know, I know. 0, 1, many. But then I also write most of
 my programs in a language whose type system has 4 levels. Four! Is
 that even a number??

   * aristid: a dubious motivation IMHO
 edwardk: i've had worse =P

   * ziarkaen: I'm thinking I can kill two birds with one stone by
 learning Haskell while producing a website, but all the birds are
 still alive at the moment.

   * ion:
 monad.bind = function (func, args) {
 return func.apply(undefined,
[value].concat(Array.prototype.slice.apply(args || [])));
 };
 is idiomatic JavaScript?

   * beaky: if stacks are recursion, what are queues?
 Hafydd: Procrastination.

   * elliott: I think lens is the first library I've seen that promises
 letting you write abstract totally-inefficient-looking
 compositional code and getting reliably good compilation which has
 actually delivered on that promise.

   * elliott: I didn't say half the things I said.

   * shachaf: The two-letter and three-letter identifiers are for
  edwardk's libraries. The one-letter identifiers are for his actual
  code.
 elliott: edwardk has non-library code?

   * neutrino: in many ways, Haskell is like this primodial soup out of
 which other languages end up springing

   * mm_freak: bruce schneier is an endofunctor that turns all
 automorphisms into identities

   * roconnor: where are all the category theoriest? why don't they
  already have all the answers for us?
 edwardk: roconnor: this is the point in your career where you look
   around for the cavalry and realize that you're it ;)

   * cmccann: multi-letter type variables is an experimental new
 extension

   * elliott: I can't remember the last time I wrote any Haskell without
 an evil grin.

   * neutrino: when you're told you have to use javascript, the viable
 alternative always remains in seppuku. and it's much more
 honorable.

   * shachaf: chrisdone: Please make Author not mandatory. [on hpaste]
 donri: shachaf: just write not shachaf and no one will ever know
 it's you

   * tac: If you're not part of the solution, you're part of the
 precipitate

   * cmccann: some people blame themselves, some people blame the
 language, but the people who really know what they're doing blame
 shachaf.

[Haskell-cafe] Haskell Weekly News: Issue 252

[Daniel Santa Cruz]

Welcome to issue 252 of the HWN, an issue covering crowd-sourced bits
of information about Haskell from around the web. This issue covers the
week of November 18 to 24, 2012.

Quotes of the Week

   * rwbarton: edwardk now has Lens under Control

   * atriq: My son looks a bit like me, he can put away the plates after
 dinner now thanks to edwardk!

   * mgsloan: Lens got 99 operators, but a (|) ain't one.

   * hiptobecubic: I feel like this program is just a bunch of glue and
 duct tape holding a bottle of nitroglycerine off of the ground.

   * xplat: Some software is worth trying; most is just plain trying.

   * edwardk: Control.Lens is my secret ploy to get everyone to give up
 on Haskell and just move on to Agda as they find the Haskell types
 too complicated by comparison.

   * rwbarton: alpha reduction is what happens when you let edwardk
 maintain your module

   * edwardk: er that was a tongue sticking out, not an operator
 suggestion

Quotes of the Week

   * Ralith: [why some people don't use conduits/pipes] also, I think at
 least some people are waiting for edwardk to write his version.

 arrows in the appropriate categories)

   * edwardk: @type (^.)
 lambdabot: s - Getting a s t a b - a
 byorgey: I would not like to be getting a stab, thank you

   * edwardk: I mean we're so oop even our member accessors have

   * shapr: hylo! That's the category theorist greeting.

   * shachaf: type AbstractAlgebra a = Abstract a - a

   * nicoo: Yet many Writers concern themselves with issues of State,
 imaginary or real

   * rwbarton: when you learn C, watch out for the keyword return, it
 doesn't do what you'd expect

week of September 30 to October 6, 2012.

Quotes of the Week

   * monochrom: 98% of people lack the property that they're members of
 the other 2%

   * ManuelChakravarty: We used to say, Learn Haskell, it makes you a
 better Java programmer. Now we say, Learn Agda, it makes you a
 better Haskell programmer.

   * Cale: data Nature a = Rock a | Stream (Nature a) | Bush (Nature a)
 (Nature a)

   * rwbarton: type inference is supposed to be the compiler's job, not
 the reader's job

   * ShelSilverstein: Lazy Lazy Lazy Lazy Lazy Lazy Jane. She wants a
 drink of water so she waits and waits and waits and waits and waits
 for it to rain.

   * Cale: We're up to 950 users which apparently means that any
 beginner question is now answered by 4 people.

   * YayMe: When I first started playing with haskell I could barely
 sleep for 2 days because of how confused it made me

   * EvanLaforge: Then we can tell them about how we had to walk in the
 snow both ways uphill fighting space leaks with bare hands while
 they just have to read about it.

[Daniel Santa Cruz]

Welcome to issue 246 of the HWN, an issue covering crowd-sourced bits
of information about Haskell from around the web. This issue covers the
week of September 23 to September 23, 2012.

Want to contribute quotes for HWN? Until today the only way to help
with those was to use @remember in the IRC channel. Now you can also
use @HWNQuotes in twitter to submit quotes for the weekly newsletter.

Quotes of the Week

   * carpi: all said ... the brain of someone of who writes compilers
 for haskell scares me nuts. I wouldn't want them concentrating on
 me, lest I catch fire.

   * Igloo: The major problem, as far as I can see, is how to construct
 the mumble'.

   * edwardk: i want to be able to know if the compiler is being stupid
 or if its just me, and without any sort of model to reason about it
 with, i always have to assume it could be the compiler; i already
 have to deal with that problem, its called 'scala'

   * ddarius: Now I can just point people at a readable and relevant
 paper instead of having to Cale it.

   * rwbarton: also, a generally safe answer to was there an update to
 lambdabot recently is no

   * camccann: you want a debugger? GHC has one. Except that stepping
 through lazy evaluation is like listening to a stream of
 consciousness narrative told by a 5-year-old with ADHD.

 Quotes of the Week

   * shachaf: You can call the greengrocer and place an order. That'll
 convert their unordered pears into ordered pears!

   * shachaf: Those who would give up essential type independence for a
 little temporary type safety deserve neither independence nor
 safety.

   * ddarius: edwardk: So your plan for Haskell adoption is to write
 Haskell in languages that aren't Haskell, say Man, these languages
 suck, this would be super easy in Haskell, and then use the
 Haskell you started with reproducing functionality at an
 unbelievable rate.

   * cmccann: personally I'm just waiting for an extension that demotes
 types to the value level, so that we can finally have natural

[Haskell-cafe] Haskell Weekly News: Issue 225

[Daniel Santa Cruz]

  Welcome to issue 225 of the HWN, an issue covering crowd-sourced bits
  of information about Haskell from around the web. This issue covers the
  week of April 22 to 28, 2012.

Announcements

  Matthias Fischmann made a call for participation to the Hong Kong
  Haskell hackathon, with tentative dates of May 11-13 or 25-27. Follow
  to link for more information.
  [1] http://goo.gl/9sRLF

  HacPhi, the hackathon in Philadelphia, Pennsylvania, USA, will be
  held between August 3-5, 2012.
  [2] http://goo.gl/Rm2qH

Quotes of the Week

   * lambdabot was last seen on #haskell 1 hour, 37 minutes and 46
 seconds ago, saying: IO ()

   * elliott: oh, it's not haskell-cafe? that explains the reasonable
  responses [it = GHC mailing list]

   * Morandat: The astute reader will have noticed that the above
   example clashes with our claim that R is lexically
   scoped. As is often the case, R is lexically scoped
   up to the point it is not.

   * quicksilver: lisp doesn't have equational reasoning so there is
  nothing to lose :)

   * JoeyA: One thing I like about Haskell versus C++ is that abusing
language features tends to give more satisfying results.
 monochrom: that seems to be a criterion for drugs rather than
languages :)

Some of these announcements are a bit behind, for which I apologize.
Better late than never...

The long awaited version of cabal-install is out!
[1] http://goo.gl/LlO7s

Janis Voigtlander is looking for contributors for the May 2012
edition of the Haskell Comunities and Activities Report. If you have
anything Haskell related that you have been working on, make sure to
send Janis a note. The deadline is May 1st.
[2] http://goo.gl/AW3gR

Jeremy O'Donoghue announced the release of wxHaskell 0.90. his
release represents a significant milestone for us as it includes
support for wxWidgets 2.9.x.

Quotes of the Week

   * TSC: The type families might have little type children

   * mm_freak: i'd love to have an embeddable Agda type checker and
   evaluator
 mm_freak: that would make a great scripting language for haskell
   programs

   * shachaf: You can't spell -funsafe without fun and safe.

   * elliott: By the way, I find the inclusion of a package named
  colour in a section titled Color offensive :)

   * elliott: I don't think Haskell can ever hope to enter the
  enterprise if we can't model non-standard colourblind
  observers with it.

   * danharaj:oh hey this looks nice.
 Mathnerd314: every open-source math library under the sun glued
  together into a Python framework
 danharaj: nevermind o_o

   * elliott: What do we do with people who paste code blocks on IRC? We
  yell at them.

   * acowley: I am a bull in a math shop

   * elliott: I like how edwardk's answer to every question always goes
  most abstract solution to the problem possible --
  microoptimisation details.
 elliott: I swear I've seen him go from category theory to unboxed
  types and unsafeCoerce in a single line of IRC.

   * shachaf: It is a sobering thought that by the time Galois was my
  age, he had been dead for almost two months.

Quotes of the Week

   * tgeeky_: What I cannot create, I do not understand. -- Richard
 Feynman, on his blackboard when he died in 1988.

   * elliott: ... [a] is more of a control structure than a data
 structure.

   * Cale: Basically, we've known how to implement first class functions
 efficiently for 20 or 30 years now, and we've known about their
 importance to abstraction in programming since before the advent of
 electronic computers. There's no excuse to still be writing new
 programs in languages without them.

   * edwardk: When someone throws an exception at you, duck.

   * luite: I think it uses levenshtein distance (he invented this
 distance because nobody could spell his name correctly)

   * edwardk: 'hey ghc devs can you fix this thing that might or might
 not be a bug so we can break a huge pile of invariants in your
 compiler to put go faster stripes on something nobody uses? k thx'

[Haskell-cafe] Haskell Weekly News: Issue 221

[Daniel Santa Cruz]

Welcome to issue 221 of the HWN, an issue covering crowd-sourced bits
of information about Haskell from around the web. This issue covers the
week of March 25 to 31, 2012.

Quotes of the Week

   * Tekmo: Now I have a monoid in the category of problems.

   * hpc: atomically the whole thing

   * BMeph (in announcer voice): In a world, where orphan instances
   collide, one language holds the key to successful compilation, in
   our time.

[Haskell-cafe] Haskell Weekly News: Issue 220

[Daniel Santa Cruz]

Welcome to issue 220 of the HWN, an issue covering crowd-sourced bits
of information about Haskell from around the web. This issue covers the
week of March 18 to 24, 2012.

Quotes of the Week

   * shachaf: Type classes are a scary story that you tell new
  Haskellers so they can go to sleep at night.

   * acowley: Parametric polymorphism is the inspiring story you tell
  them to get them riled up and raring to go.
  It's like Braveheart for programmers.

   * monochrom: the purpose of types is to ban more programs

   * rostayob: I was a type constructor, then I took an arrow in the
   kind

   * shachaf: @let otherfoolish = not otherwise

   * flebron: Monoidal objects in the monoidal category of endofunctors
  on a category. I took a small detour through tensor
  products to understand monoidal categories better, with
  one example of such a product.
 mauke: I have no idea what you just said

   * weexplat: starts a proposal to replace launchMissiles with
   atomicDestroyBiosphere

   * monochrom: rumour: SPJ will write a thick book A New Science of
Kind

   * JonathanShapiro: [on abandoning BitC] And I *still* don't believe
  in monads. :-)

25, 2012.

Quotes of the Week

   * nand`: oh, wait, ANSI is the physical layout

   * cmccann: some programmers have a problem to solve and think I
 know, I need an existential type. now they have another problem,
 but can't solve it because all they know about it is that the

   * hpc: peano arithmetic Z life

   * cmccann: unicode snowman is a valid identifier in Haskell, BTW

   * Jafet: Haskell is an imperatively functional abstract enterprise

   * Brandon Allbery: If you absolutely insist on shooting yourself in
 the foot this way in Haskell, it can be done; but there is no

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

http://contemplatecode.blogspot.com/2012/02/haskell-weekly-news-issue-214.html

Quotes of the Week

   * Jafet: [on memoising an O(n) algorithm:] This is like trying to
 save work in a police investigation by having each detective
 determine whether another detective has already removed all
 evidence from his area by walking through it to search for evidence
 in the area.

   * CodeWeaver: keep in mind encryption's only as good as how much you
 trust that the implementors got it right.

   * cmccann: length [1..10^20]
 lambdabot: mueval-core: Time limit exceeded
 cmccann: looks like 10^20 is infinity

   * elliott: race condition waiting to happen

   * elliott: o'reilly publishes attoparsec tutorial: exactly the same
 as their parsec tutorial, but 10^-18th the size

   * rwbarton: Num works for Float/Double, it's Float/Double that
 doesn't work for Num

   * ddarius: Space isn't that big.

   * Brent Yorgey:
  Sometimes, I suspect that Haskell not only makes easier of the hard
  things for imperative programming languages but also makes harder of
  some easy things.

 This is true.  But usually these are things that you don't *want* to
 be easy, like shooting yourself in the kidney. (But these features are
 often described in ways that make them sound great, like flexible
 usage of bullet-placement tools.)  Inserting arbitrary print
 statements into the middle of some code is difficult for a reason.

[Haskell-cafe] Haskell Weekly News: Issue 211

[Daniel Santa Cruz]

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?

Quotes of the Week

   * dankna: I do [gui on osx] by writing a polyglot ObjC/Haskell
 program
   * maurer: I'd do it kmc style
   * hpc: your next challenge: write a definition of fix in java that
 fits in a twitter post
   * kmc: i leave for 3 seconds and you're all metaprogramming and shit
   * acowley: Haskellers are so abstract they can't even spell primitive
   * edwardk: i was happy that i had the 4th entry on google for a
 topic... but then i realized it was only for me, not for everyone
 that searches for it
   * kmc: oh, my suggestion was to hand off the fd's directly through a
 UNIX socket ... but that's probably silly ... i just like the fact
 that fd's can be passed through a unix socket
   * monochrom: linear types change the world! says Wadler. Record
 updates change the type! says Haskell. :)
   * gosu: Type parameters are covariant. This is not sound, and that
 does not matter.
   * Yitzchak Gale: I certainly wouldn't dream of dragging in type-level
 olegery, unsafe coercion, implicit parameters and other
 experimental extensions. Simplicity just works.

Quotes of the Week

   * kmc: when computer scientists rebuild the world after the
 apocalypse, we will have hanging gardens with trees that grow
 downward

   * kmc: a wise man once said that the entire world can be described as
 convex combinations of drugs, math, and cardboard

   * roconnor: as a rule of thumb, avoid any packages shipped with the
 Haskell Plaform.

   * kmc: Try the new GHC IO Scheduler! It's got what plants crave!

   * kmc: I refuse to believe that any loving god would invent the
 monomorphism restriction

   * AlanPerlis: It is easier to write an incorrect program than
 understand a correct one.

   * [kmc] do you have a theory where the stack overflow is
coming from?
 [copumpkin] joel spolsky

   * @faq is it possible to find things Haskell can't do?
 [lambdabot] The answer is: Yes! Haskell can do that.

   * kmc: Haskell isn't really designed by mathematicians. it's designed
 by people who programmers would consider to be mathematicians and
 mathematicians would consider to be programmers

 told all hope was lost, then simonmar swung in on his web shooters
 and figured it out

   * quicksilver: agda is an alluring trap for haskell programmers who

[Haskell-cafe] Haskell Weekly News: Issue 189

[Daniel Santa Cruz]

   Welcome to issue 189 of the HWN, a newsletter covering developments in
   the Haskell community during the week of June 26 to July 2, 2011.

   It seems that it was a pretty quiet week in the mailing list. There
   were no significant announcements made, and the number of threads was
   low by comparison. Hope everyone is having a great week!

   You can find the HTML version at:
   
http://contemplatecode.blogspot.com/2011/07/haskell-weekly-news-issue-189.html

Quotes of the Week

   * iwtu: [#haskell] is a good channel. Really. People are helpful and
 don't deserve killing or eating

   * [Cale] Finite dimensional vector spaces over a field F are
 algebras for the monad of F-linear combinations of elements of a
 set.
 [ivanm] h _now_ I get you!

   * [quicksilver] C++ templates can embed arbitrary computation at
 compile time
 [quicksilver] that alone tells you something about the
 complexity of the compiler
 [edwardk] yeah. they were accidentally turing complete. (whoops!) ;)
 [quicksilver] edwardk: OOPS I ACCIDENTALLY THE WHOLE TARPIT

   * bos: other companies use expensive firewalls and crypto hardware to
 protect their intellectual secrets. edwardk uses category theory!

   * ManuelChakravarty: After all, you can import any C function with a
 pure type which also allows you to wreak arbitrary havoc. We enable
 the user to disguise arbitrary machine code as a Haskell function
 of essentially arbitrary type. In comparison, `unsafePerformIO'
 seems angelic.

   * NihilistDandy: The best part of Haskell is that 80% of module names
 can be turned into clever blog titles.

   * AlanPerlis: We will never run out of things to program as long as
 there is a single program around.

[Haskell-cafe] Haskell Weekly News: Issue 188

[Daniel Santa Cruz]

   Welcome to issue 188 of the HWN, a newsletter covering developments in
   the Haskell community. This release covers the week of June 19 to
   25, 2011.

   It was brought up in cafe this week that some would prefer to see
   full links in the text version of the mailing list as opposed to the
   shortened links. The reason behind using shortened links is that the
   newsletter becomes pretty much unreadable with long links in a plain
   text buffer. In an effort to accommodate both needs, I'm trying a new
   format for links. One that includes shorter links embedded throughout
   the newsletter, and the full reference at the bottom of the text. Let
   me know what you think!

   If you are reading this on a mobile device, or you would just rather
   see the HTML version, point your browser to:

Announcements

   Alex Mason wrote in to remind us that AusHac2011 (the Australasian
   Haskell Hackathon) will be held on July 8-10, at UNSW in Sydney. If
   you are an Australian haskell hacker, enthusiast, newbie or
   professional, we would love to see you there.

   * Toxaris: #haskell delivers a massively multiprogrammer online
 functional programming (MMOFP) experience

   * sully: although I'm switching to haskell more and more just on
 practical grounds

   * mauke: the greek letter lambda is an imperfect approximation of the

You could always just subscribe to the HWN feed on Contemplating Code. I just 
load up my reader when I don't want to read the text dispatches. Try

   http://contemplatecode.blogspot.com/feeds/posts/default?alt=rss

That's the feed URL I use. Then the one on the mailing list is your plaintext 
fallback. :D

 In the plaintext email I'd prefer full URLs to cut/copy on my computer

  Short, obfsucated, urls may direct you places you don't want to go,
  but I fail to see how that concern applies to HWN: since each url is
  accompanied by a description of its content, that seems to obviate the
  need to see the actual url.  In most cases, the text also indicates
  the domain that you will visit, so you can avoid supporting
  stackoverflow with page impressions if you wish (for example).

 It is also possible to borrow half of Slashdot's system and write something
 like

  http://goo.gl/G081Q [article.gmane.org]

 Is that a good compromise?


That is a nice in-situ style. Someone please correct me if I'm wrong, but I
think the footnote proponents' main argument is that its lightweight nature
causes less of an interruption when reading the text.

I think its fair to say that those who RTFA more often would benefit most
from in-situ and those who rarely RTFA benefit most from the footnote style.
I'm in the former group, but who knows what most people do?

My solution is to never read the text version and only ever read the 
HTML version. Works great for me. :-)

Lyndon,

The links are minimized in hopes of making the plain text version
somewhat readable. It is purely for aesthetical reasons. If you view
the web version
http://contemplatecode.blogspot.com/2011/06/haskell-weekly-news-issue-187.html
you'll see that they are not minimized there.

FYI, a regular link (though longer) seems more appropriate to me.

But anyway, thanks for the HWN (in either short or the long form)!

If we switch to long links, could they be forward referenced in the
footer, so as to not disrupt the flow of the text, as the HWN used to
be? (if I remember correctly.)
