Issue 141 - November 29, 2009
---------------------------------------------------------------------------
Welcome to issue 141 of HWN, a newsletter covering developments in the
[1]Haskell community.
Firstly, sorry for the late HWN, a turkey coma is equal parts gift and
curse. This week, we have some very exciting news, a new Haskell
standard -- Haskell 2010 -- was announced, including several small
changes. Also, we have lots of new packages, a possible Boston-area
Hackathon coming up soon, and some great discussion. I won't hold you
back from skipping all that and just reading the funny quotes!
Haskellers, your (belated) Haskell Weekly News!
Announcements
Haskell 2010. Simon Marlow [2]announced the new revision of Haskell,
Haskell 2010. Part of the new, less monolithic Haskell Prime process,
Haskell 2010 includes several changes to the Haskell Language,
including support for nonstandard if-then-else syntax (particularly wrt
`do` notation and indentation), pattern guards, and several other
changes. See the post for details.
Clutterhs 0.1. Matt Arsenault [3]announced Clutterhs, version 0.1. A
set of bindings for Clutter, a GObject based library for creating 2.5D
interfaces using OpenGL.
Interesting experiences of test automation in Haskell? Automation of
Software Test 2010. John Hughes [4]announced a 'heads up' for the
Automation af Software Test 2010 workshop
NoSlow - Microbenchmarks for array libraries. Roman Leshchinskiy
[5]announced his benchmark suite for various array and list libraries.
CMCS 2010: First call for papers. Alexandra Silva [6]announced a first
call for papers for the Tenth International Workshop on Coalgebraic
Methods in Computer Science, taking place 26-28 March 2010, in Paphos,
Cyprus.
GPCE'10 First Call for Papers. Bruno Oliveira [7]announced a first call
for papers for the Ninth International Conference on Generative
Programming and Component Engineering. GPCE 2010 October 10-13, in
Eindhoven, The Netherlands.
Call for Participation: TLDI'10. Andrew Kennedy [8]announced a call for
participation in the 2010 ACM SIGPLAN Workshop on Types in Language
Design and Implementation
Deadline Extension: JSC Special Issue on Automated Specification and
Verification of Web Systems. demis [9]announced an extension to the
paper deadline for the JSC Special Issue on Automated Specification and
Verification of Web Systems.
VSTTE 2010: Verified Software -- Second Call for Papers. Gudmund Grov
[10]announced the second call for papers for the Third International
Conference on Verified Software: Theories, Tools, and Experiments
GPipe-1.1.0 with greatly improved performance. Tobias Bexelius
[11]announced a new version of the GPipe package, now with greatly
improved performance.
wumpus-core. Stephen T [12]announced a new version of the wumpus-core
package, a library for drawing 2D vector pictures, supporting output to
SVG and postscript.
package-vt-0.1.3.3, Haskell Package Versioning Tool. Krzysztof
Skrzetnicki [13]announced the first release of his automatic version
tracking tool, package-vt.
Elerea 1.1. Patai Gergely [14]announced a new version of Elerea, a
simple pull-based FRP library. Elerea (and FRP in general) allow for
stream oriented programming, typically done in a applicative style.
mecha-0.0.4. Tom Hawkins [15]announced a new version of Mecha, a little
constructive solid modeling language intended for doing 3D CAD.
atom-0.1.2. Tom Hawkins [16]announced a new release of Atom, a DSL for
designing hard realtime embedded software with Haskell. This release
adds guarded division operations, a new scheduling constraint, and a
new rule scheduling algorithm.
Managing Cabal Dependencies using Nix and Hack-nix. Marc Weber
[17]announced a package for dealing with Cabal dependencies on the Nix
OS platform.
Discussion
haskell in online contests. vishnu [18]asked about using Haskell in
online contests, and particularly dealing with the SPOJ tool for
judging programs.
Namespaces for values, types, and classes. Sebastian Fischer
[19]suggested allowing a namespace separation between class-names and
other language elements.
I miss OO. Michael Mossey [20]lamented his desire for Object-oriented
features in Haskell, this led to a interesting discussion about name
punning and typeclasses.
Haskell Hackathon in Boston January 29th-31st? Ravi Nanavati
[21]proposed a potential Hackathon in this editor's favorite city, to
be held the 29th to the 31st.
