[Haskell-cafe] Haskell Weekly News: Issue 225
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.

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 :) Top Reddit Stories * Darcs 2.8: faster, better annotate; patch stash (obliterate -O); revert hunk split; and more!

[Haskell-cafe] Haskell Weekly News: Issue 189
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 186
Glad you are reading this issue! This is issue 186, not 180... Seems that the last couple of issues got stuck on 180. Hopefully you will find pointers to interesting things happening in the Haskell community. This issue covers the week of June 05 to 11, 2011. Announcements Hakim Cassimally shared with us slides and screencast from Geekup's first ever Functional Programming Night. http://goo.gl/1oCO8 Johannes Waldmann sent an invite to a Local Haskell Meeting (Stammtisch) in Leipzig, Germany on June 27. http://goo.gl/UM9ci We are very proud of the two Simons, Simon Peyton Jones and Simon Marlow. Isaac Potoczny-Jones relayed the announcement from ACM SIGPLAN of the SIGPLAN Programming Language Software Award. Many congrats! http://goo.gl/sAuVv Quotes of the Week * augustss: So JHC has bad code. GHC had a lot of that a long time ago, and they have slowly been converting to the pure way. It's the only sensible way. * geheimdienst monochrom: i thought it maybe would end executing the current do block ... monochrom use when. mm_freak_ use goto hpc use Java * cmccann: programming is a lot easier if you avoid working with dates/times, text, or numbers. I say stick to category theory, it's simpler * xplat: the underlying graph of a category is transitive. transitive graphs have no bridges. this is why trolls always have problems with category theory.

[Haskell-cafe] Haskell Weekly News: Issue 181
Welcome to issue 181 of the HWN, a newsletter covering developments in the Haskell community. This release covers the week of May 1 to 7, 2011. Announcements Last week I failed to note the announcement [http://goo.gl/ApClU] of a new version of Leksah (0.10.0). If you haven't yet, give Leksha a test run and send some feedback! Ketil Malde started a thread [http://goo.gl/Prlu2] about Robert Harper's thoughts on monads and laziness. Hakim Cassimally extended an invitation [http://goo.gl/QIjcF] to anyone living in the Northwest UK for Tuesday May 31st to Geekup's first ever Functional Programming Night. Andy announced [http://goo.gl/uCEn1] a new release of Manatee (0.2.1). Quotes of the Week * hpc: [SPOILER] You can check wikipedia for the definition of fibonacci sequences if you get stuck after half an hour * pmetzger: it is always possible to make an algorithm slower. just give it to a CS freshman to code up. * kmc: ghc -XMixfixOperators -XDependentTypes -XMakeMeASandwich * pmetzger: I have my password tattooed to my forehead. that way when I forget it others can tell me what it is. * alexbagel: i find that my first 26 variables are always easy to name. after that it becomes a bit harder. * Eric Kow: Haskell is a good fit for me because I tend to practise Doh!-oriented programming Top Reddit Stories * More points for lazy evaluation Domain: augustss.blogspot.com, score: 56, comments: 24 On Reddit: http://goo.gl/qecQ1 Original: http://goo.gl/OnJXx * iterIO: iteratee-based IO with pipe operators, courtesy David Mazieres Domain: haskell.org, score: 43, comments: 15 On Reddit: http://goo.gl/YzPJn Original: http://goo.gl/6WQAk * Monad comprehensions are finally in GHC Domain: self.haskell, score: 37, comments: 32 On Reddit: http://goo.gl/1Rjnw * Horner's Rule Domain: patternsinfp.wordpress.com, score: 34, Comments: 2 On Reddit: http://goo.gl/A1wYo Original: http://goo.gl/zeC1f * Patent 5,893,120 reduced to mathematical formulae (via Haskell) Domain: paulspontifications.blogspot.com, score: 31, comments: 13 On Reddit: http://goo.gl/PmB4K Original: http://goo.gl/QknmV * Custom Haskell mug!
