Haskell Weekly News: July 02, 2008

Welcome to issue 75 of HWN, a newsletter covering developments in the Haskell community.

Announcements

Anglo Haskell 2008. Matthew Sackman announced AngloHaskell 2008, a gathering of all people Haskell-related from beginners, to seasoned hackers to academic giants. All and more are welcomed by large fuzzy green lambdas. The proposed dates and location are Friday the 8th and Saturday the 9th of August, at Imperial College, London.

CFP - Special Issue of Fundamenta Informaticae on Dependently Typed Programming. Wouter Swierstra announced a call for papers for a special issue of Fundamenta Informaticae on Dependently Typed Programming. The deadline for submissions is October 1.

Gtk2Hs 0.9.13. Peter Gavin announced the release of Gtk2Hs 0.9.13, including bindings for Gnome VFS and GStreamer, a new Gtk+ tutorial adapted by Hans van Thiel, cairo image stride support, and more.

Hasim. Jochem Berndsen announced Hasim, a small project to create a library to do discrete event simulation in Haskell, using monads to define a domain-specific language for "actions" of a process.

Galois move. Don Stewart announced that Galois has completed the move of its data center. Expect speedier response times for hackage.haskell.org and darcs.haskell.org.

Google Summer of Code

Progress updates from participants in the 2008 Google Summer of Code.

Hoogle 4. Neil Mitchell (ndm) is working on Hoogle 4. This week, Neil worked on better Haddock database generation, lazy name searching, and a snazzy --info flag for Hoogle. Next up: type search!

DPH physics engine. Roman Cheplyaka (Feuerbach) is working on a physics engine using Data Parallel Haskell. This week, he worked on implementing Mirtich's V-Clip algorithm for collision detection (and got it to work), cabalized his project and added documentation. He also ran into an interesting QuickCheck puzzle.

Generic tries. Jamie Brandon is working on a library for efficient maps using generalized tries. This week, he created a generic framework for automatically running QuickCheck tests at a number of different types. This week he plans to synthesize the many suggestions from the discussion on the libraries list into a stable API design.

Language.C. Benedikt Huber (visq) is working on Language.C, a standalone parser/pretty printer library for C99. This week he worked on a better representation for declarators, and abstracted the notion of an InputStream over both String and ByteString, among other accomplishments.

GHC plugins. Max Bolingbroke is working on dynamically loaded plugins for GHC.

Cabal dependency framework. Andrea Vezzosi (Saizan) is working on a make-like dependency analysis framework for Cabal.

GHC API. Thomas Schilling (nominolo) is working on improvements to the GHC API. Officials at HWN headquarters have released a statement reversing their previous position regarding the existence of Thomas, citing regrettably faulty information to explain their previous misapprehensions. Expect to hear more from Thomas soon, now that he has finished graduating and moving.

Libraries

Proposals and extensions to the standard libraries.

GetOpt formatting improvements. Duncan Coutts proposed some modifications to make the output of the System.Console.GetOpt library more readable, resulting in quite a bit of discussion.

HughesPJ improvements. Benedikt Huber proposed a patch with some bug fixes, performance improvements, and QuickCheck test suite for the Text.PrettyPrint.HughesPJ pretty-printing library.

Discussion

A Monad for on-demand file generation?. Joachim Breitner asked about a monad for transparently tracking files which may need to be regenerated due to dependencies, leading to an interesting discussion of incremental computation, strict vs. lazy I/O, and other issues.

New mailing list proposal: Haskell-Edu. Benjamin L. Russell sent out a message proposing a new mailing list hosted at haskell.org, "Haskell-Edu: The Haskell Educational Mailing List." The new mailing list would be guided by the principle that Haskell is useful not just in research, but also in teaching programming as part of a liberal arts education. Comments and discussion welcomed.

Learning GADT types to simulate dependent types. Paul Johnson is trying to use GADTs to simulate aspects of a dependently typed system, and asks for help improving his Oleg rating.

Call graph tool?. C.M.Brown asked whether there is a tool for visualizing the call graph for a collection of source files, leading to a discussion of various tools.

Jobs

Formal methods and automated reasoning at Rockwell Collins. Janis Voigtlaender passed on an opening for a Senior Systems Engineer at Rockwell Collins. The opening is for a computer scientist or engineer to develop and apply automated analysis to computer systems and to pursue research in formal methods and automated reasoning. Contact: rmgatto at rockwellcollins.com.

Haskell Weekly News: June 25, 2008

Welcome to issue 74 of HWN, a newsletter covering developments in the Haskell community.

This week, you'll notice a bit more detail in the 'Blogs' section. I've added summaries to some of the posts, to help you decide which you might be interested to read (only a few this week, since I added them at the last minute). I've also >>> highlighted blogs not syndicated on Planet Haskell---mostly people who have just begun learning Haskell and decided to blog about it. Go show them some comment love, and invite them into the community!

Community News

Andrew Wagner (chessguy) recently flew out to Microsoft for an interview with their Live Search team. In an email to the cafe, he shares some stories from his experience and some interesting coding challenges.

Google Summer of Code

Progress updates from participants in the 2008 Google Summer of Code.

Hoogle 4. Neil Mitchell (ndm) is working on Hoogle 4, and recently added two new features, multi-word search and intelligent suggestions.

DPH physics engine. Roman Cheplyaka (Feuerbach) is working on a physics engine using Data Parallel Haskell. This week he intended to implement simple ad-hoc cubic collision geometry to test collisions with rotation, but the code became too cumbersome and non-extensible. He took a break to read some papers, and found a better solution.

GHC plugins. Max Bolingbroke is working on dynamically loaded plugins for GHC. This week he worked on adding arbitrary user-specified phases to GHC, implementing a control system, pipeline generation, and Template Haskell integration. Next he plans to work on a plugin annotation system.

Language.C. Benedikt Huber (visq) is working on Language.C, a standalone parser/pretty printer library for C99. This week he worked on AST documentation and improvements, prepared to port the AST analysis from c2hs, and worked on the pretty printer's internals.

Generic tries. Jamie Brandon is working on a library for efficient maps using generalized tries. Recently he has worked on implementing some bitpacking tools to save memory.

GHC API. Thomas Schilling (nominolo) is supposedly working on improvements to the GHC API. However, officials at HWN headquarters have begun privately speculating that Thomas does not, in fact, exist.

Discussion

history of tuples vs pairs. Conal Elliott asked about the history of support for n-tuples in Haskell and ML.

hackageDB maintainer policy. Ross Paterson began a lengthy discussion towards agreeing on a policy for uploading packages to Hackage, specifying whether the package is maintained and who is maintaining it, and other related issues.

What is a rigid type variable?. Xiao-Yong Jin asked what the 'rigid type variables' are that are sometimes referred to in GHC error messages. Read the thread for a concise discussion and the solution to the original problem.

Map interface. Jamie Brandon started a thread asking for feedback on his proposed API for generic tries, and the discussion is still ongoing.

Left and right folds. George Kangas exhibited a pair of very elegant alternate definitions for left and right fold, and showed how this alternate viewpoint makes obvious several algebraic identities as well as the generalization to Data.Foldable. A must-read for the aspiring functional programmer.

ribbonsPerLine. Alfonso Acosta asked an interesting question about "ribbonsPerLine" in the Text.PrettyPrint.HughesPJ library. Do you know what it does? The answer can be found in the original paper describing the library.

Jobs

PhD position at University of Strathclyde, Glasgow. Simon Marlow announced, on behalf of Patricia Johann, an open PhD position in operational and categorical approaches to parametricity. The funded position is in the newly-formed Mathematically Structured Programming group at the University of Strathclyde, comprising Neil Ghani, Patricia Johann, and Conor McBride.

Haskell Weekly News: June 11, 2008

Welcome to issue 72 of HWN, a newsletter covering developments in the Haskell community.

Greetings, Haskellites! As many of you have already heard, Don Stewart has passed on the editorship of the HWN to me (Brent Yorgey). I'd like to thank Don and John Goerzen for their great work putting it together in the past, and I'm excited to make the HWN once again into a reliable, useful compendium of happenings in the Haskell community. You can expect to see a few changes---for example, hackage uploads will no longer be listed in the HWN (unless they are announced on the haskell or haskell-cafe mailing lists), since you can now see a dynamically updated list on the front page of the Haskell wiki. This edition includes all the announcements going back to Issue 71, but only some of the blog posts, since I couldn't find a way to get old feed data from Planet Haskell. Hopefully next week things will settle down to something more normal(ish) and I can begin tinkering with the format. Feel free to send suggestions and/or stories for inclusion to me, byorgey at gmail dot com. Enjoy---'Putting the W back in HWN!'

Quotes of the Week

  • teamonkey: the Haskell solutions that people are posting are generally so much more concise and elegant than for any other language
  • Dan Zwell: I am fairly new to Haskell, and I didn't realize how easy concurrent code is until I wrote this
  • anonymous: The Haskall (sic) language is often uses by very intelligent programmers, it often allows to use lazy computations and iterations, but it has the advantage that its iterators behave better (than in Python), and during the generation of some items you can, when you want, refer and use the items already generated.
  • Corun: I don't understand, what's the advantage of hugs? The uni here says to use hugs, though, but I kept finding myself going in to ghci to get a useful error message
  • They say that if it compiles, it will run correctly. It?s nearly true! I?m amazed. ... Such buglessness will remove a huge source of indeterminism in production environments where the work of many teams is co-ordinated by schedules.
  • dolio: I've made a domain specific notation for describing puddings.
  • cschneid: [Haskell] changed the way I look at decomposition of problems in the more corporate languages (Java and C#). I use far fewer variables, and more side-effect free methods. It's made my code clearer, and easier to test.
  • nicodemus: I've written some Erlang and much more Haskell. My take so far is that Erlang is good for teaching you how to fish, Haskell is good for teaching you about procuring food (including fish).
  • paulzork: Haskell is to functional programming like C is to imperative languages? Sort of the latin root?
