ANNOUNCE: ioctl 0.0.1
by Maciej Piechotka 13 Sep '15

13 Sep '15

A package for type-safe I/O control. Currently only ioctl is supported. Currently simply a extract from my tuntap fork TODO: - Return the integer as well as structure (will break the API) - Port for Windows Network.Socket.IOCtl (as soon as I manage to setup some sane environment on this platform) - Wrapping around DeviceIoControl Example (in hsc): data NotRead = NotRead instance NotRead Int where ioctlReq _ = #const FIONREAD notRead s = ioctlsocket' s NotRead Regards

[ANN] haddock-2.15-0, haddock-api-2.15-0, haddock-library-1.1.1
by Mateusz Kowalczyk 31 Aug '14

31 Aug '14

Hello, I'd like to announce the release of Haddock 2.15.0. Before we dive in, I'd like to announce that Haddock development has moved out of the GHC tree and is now done against the latest compiler release. If in the past you wanted to contribute but were intimidated by having to make sure it works against GHC HEAD then here's your chance. Additionally, it now should also work with GHC 7.8.2 so if for whatever reason you're forced to use that, you can now get the latest Haddock features. If you want to contribute then please let us know, we're understaffed! Come chat at #haddock or send us an e-mail. If you have been using 2.14.x, you should be good to simply ‘cabal install haddock’. Now the changes: This is an API-breaking bugfix release so any tickets originally scheduled for 2.15.0 were pushed towards 2.16. Perhaps the biggest change is that ‘cabal install haddock’ will now only give you the Haddock binary. To use Haddock API, please depend on ‘haddock-api’ from now on. I have sent out an e-mail about this couple of weeks in advance to any reverse dependencies of ‘haddock’. This is to workaround cabal's inability to pass flags to dependencies from the cabal file. ‘haddock-library’ only got a minor bump, 1.1.0 → 1.1.1 improving its output. The Monoid instance for DocH is gone however as it was ill-formed to begin with. Changes in version 2.15.0 * Always read in prologue files as UTF8 (#286 and Cabal #1721) * parser: don't wrap headers in DocParagraph (#307) * parser: don't mangle append order for nested lists (pandoc #1346) * parser: preserve list ordering in certain scenarios (#313) * parser: update the attoparsec version used internally giving slight parsing performance boost. * Move development to be against latest GHC release and not GHC HEAD. * Further split up the package to separate the executable from the library, necessary by things like GHCJS. We now have ‘haddock-library’ which are the parts that don't use GHC API, ‘haddock-api’ which are (some of) the parts that do use GHC API and ‘haddock’ which merely provides the executable. * Export few extra functions in the API. * Add compatibility with GHC 7.8.2. * Omit unnecessary ‘forall’s (#315 and #86) * Remove some files which were really old or did not belong in the repository in the first place. Once again, we'd love to have more people on board be it for the HTML backend, refactoring, LaTeX/Hoogle backend, parser improvements, test writing, new feature implementation or bug fixing. Our issue tracker[1] is up to date if you are interested. Thanks! [1]: https://github.com/haskell/haddock/issues -- Mateusz K.

ANN: Agda 2.4.2
by Andreas Abel 29 Aug '14

29 Aug '14

Agda 2.4.2 has been released! It comes with an experimental implementation of "type" classes (see "instance search" below). Download with cabal install Agda-2.4.2 (might need cabal update first) or go to http://wiki.portal.chalmers.se/agda/pmwiki.php?n=Main.Download. Highlights: - Recursive instance search. Instance arguments are much faster than before and now work like a proper class system. - Major improvements to reflection - Quoting and unquoting of declarations and pattern matching lambdas. - New syntax to simplify using reflection: tactic f is sugar for quoteGoal g in unquote (f g) More details here: https://github.com/agda/agda/blob/2.4.2/doc/release-notes/2-4-2.txt -- Andreas Abel <>< Du bist der geliebte Mensch.

Postdoctoral Researcher at Stevens Institute of Technology in domain-specific languages, security and privacy
by Dominic Duggan 29 Aug '14

29 Aug '14

Stevens Institute of Technology Department of Computer Science has an open position for a Postdoctoral Researcher in the fields of domain-specific languages, security and privacy, and mobile technologies for health information systems in Low and Middle Income Countries (LMIC). The MEDDC project (Mobile eHealthcare Delivery for Developing Countries) is a NIH and NSF-funded project that is developing and deploying tools for data collection and healthcare management in LMIC. It is affiliated with Central Africa IEDEA (International Epidemiological Databases to Evaluate AIDS), one of several NIH-funded projects that are engaged in data collection and analysis as part of the fight against the HIV/AIDS pandemic. The project has developed tools for producing data collection systems from declarative specifications. Some of the work to be done will involve adapting ideas from statistical and functional programming languages, to pursue a domain-specific language approach to developing local capacity for data analysis. This effort has a significant software development component. Although the IEDEA project employs full-time software developers to support data collection, this research work also includes software deliverables, as described. The development language is Java, but the applicant will preferably also have experience with, and enthusiasm for, functional programming languages such as Haskell and some of its domain-specific derivatives. Research opportunities include the adaptation of concepts from functional programming languages to build local capacity for medical and epidemiological analysis in LMIC, as well as the investigation of security and privacy issues in the collection and analysis of patient health information. For further information, please contact Professor Dominic Duggan ( dduggan(a)stevens.edu, dd(a)dominicduggan.org) Applications for the position should be submitted via this Web site: https://www2.apply2jobs.com/Stevens/ProfExt/index.cfm?fuseaction=mExternal.… Applicants for the position should also forward a copy of their application to Prof. Duggan, at the emails above. Job requirements: - PhD (or equivalent degree) in topics related to domain-specific languages, security and privacy, and mobile technologies. - Excellent Java programming skills. - Preferably a strong functional programming background. - Commitment to doing high-quality research. - Oral and written proficiency in English. -- Dominic Duggan Associate Professor, Computer Science Stevens Institute of Technology Hoboken, NJ 07030.

Fwd: [racket-dev] Call for Participation: SPLASH Educators Symposium
by Robby Findler 27 Aug '14

27 Aug '14

Do consider checking out SPLASH-E, as below. Best, Robby ---------------------------- SPLASH-E Call for Participation Tuesday, Oct 21 2014, Portland OR In conjunction with the SPLASH conference http://2014.splashcon.org/track/splash2014-splash-e SPLASH-E is a forum for software and languages researchers with activities and interests around computing education. This year's SPLASH-E will feature sessions around three themes: * Creating (and Assessing) Projects and Courses to Engage Students * Design Issues around Drag-and-Drop languages * Designing Software Engineering Courses as well as time dedicated to impromptu discussion around these and other topics that arise. Formal presentations will be short (15-20 minutes), designed to raise questions for discussion rather than to simply present papers. The PC is framing discussion questions within each theme, but also welcomes questions on these topics from the broader SPLASH community. If you have a research question or idea related to these themes and plan to attend, drop me a line so we can include your question in the discussion period. Come experience an interactive day of discussion on educational aspects of software systems. Hope to see you in Portland! Kathi Fisler SPLASH-E chair

After 359 days, I'm pleased to announce the first official release of Goatee, a game editor for the board game Go. (Don't worry, those two remaining liberties are eyes.) Here's the project summary: > Goatee is a Go library and game editor, written in Haskell. It > provides a GUI for recording, studying, and editing game records. > Underneath this is a portable library for manipulating SGF files to > build UIs and tools. Goatee aims to be full-featured by supporting > all of the SGF spec and allowing for full and easy customization of > the game records you create. UI features include: - Game navigation, variations and variation modes, game tree restructuring. - Annotations: marks (r/w), arrows and lines (r/o), visibility (r/o). - Full support for game info. - Manual editing of SGF properties. - One-color and blind Go modes. Two Hackage packages are available: 'goatee' is the shared library, and 'goatee-gtk' is the UI. Lots more is planned; stay tuned! http://khumba.net/projects/goatee http://hackage.haskell.org/package/goatee http://hackage.haskell.org/package/goatee-gtk Cheers, Bryan
