--------------------------------------------------------------------------- Haskell Weekly News http://sequence.complete.org/hwn/20091213 Issue 142 - December 13, 2009 --------------------------------------------------------------------------- Welcome to issue 142 of HWN, a newsletter covering developments in the [1]Haskell community. First of all, apologies for the late edition, I've only one set of finals left, and then everything should return to a normal schedule (at least, that's the plan). This week brings lots of development on the various usb utilities, an edition of the Haskell Web News (which covers, in summary, the events of the previous month in the Haskell online community), and some really great discussion about why Haskell is Pure. Until next week, Haskeller's, your Haskell Weekly News! Announcements Next meeting: December 17th at MIT (32-G882). Ravi Nanavati [2]announced the next meeting of the Boston Area Haskell User Group. Ryan Newton will be talking about Intel Concurrent Collections for Haskell. PCLT-0.1 and PCLT-DB-0.1. Andrey Sisoyev [3]announced his first two packages he's developed in Haskell. Both of his new packages relate to localization of packages. Announcing a summer internship for a NASA-sponsored project. Lee Pike [4]announced a new summer internship sponsored by NASA and Galois, Inc. unicode-symbols-0.1.1. Roel van Dijk [5]announced the release of his package 'unicode-symbols'. This packages offers alternative symbols for a number of common function and operators from the base and container packages. ls-usb-0.1.0.2. Roel van Dijk [6]announced a minor update of ls-usb, his package for listing USB devices connected to your system. usb-safe-0.1. Bas van Dijk [7]announced the release of his package usb-safe, which provides an abstract interface to the bindings-libusb library. usb-0.3. Bas van Dijk [8]announced a new release of his 'usb' library for high-level communication with usb devices from Haskell. bindings-libusb-1.4.2. Bas van Dijk [9]announced a new version of bindings-libusb, a DSL based, low level binding to libusb The Haskell Web News: December 2009 Edition. Don Stewart [10]announced the Haskell Web News for December. new installment of failure framework. Michael Snoyman [11]announced the next installment of the Failure Framework. PortAudio Windows Tutorial and Binaries. M Xyz [12]announced a tutorial for setting up PortAudio on Windows readline-statevar-1.0.1.0. Krzysztof Skrzetnicki [13]announced a small wrapper for readline. hakyll-0.1. Jasper van der Jeugt [14]announced Hakyll, a simple static site generator written in Haskell. Discussion Why? John D. Earle [15]asked about what benefits of purity in Haskell. Type system speculation. Andrew Coppin [16]asked about why we Haskeller's (including himself) are so obsessed with the type system. To Hackage or not to Hackage. John Van Enk [17]asked about whether it was worth putting a package on Hackage. Hayoo and Hoogle (beginner question). drostin77 [18]asked our 'Hopefully Helpful Haskell Community' about the differences between Hoogle and Hayoo.
