Hac4: Haskell Hackathon

Dates: Apr 11-13, 2008.

Chalmers University of Technology, Göteborg, Sweden


1 About

The 4th Haskell Hackathon will be held over 3 days, April 11-13 2008, at the Department of Computer Science and Engineering at Chalmers University of Technology in Göteborg, Sweden. It is a coding festival, focusing on producing and improving Haskell libraries, tools and infrastructure.

To attend please register, and get ready to hack!

The Hackathon itself will be free, but you will have to pay for travel, accommodation and food.

2 Registration

If you will be attending add your name to the Registration page. Numbers may be limited, depending on availablity of space.

3.1 Getting there

3.1.1 Air

There are two airports close to Göteborg, Göteborg Landvetter Airport (GOT) and Göteborg City Airport (GSE). Landvetter airport is the main airport. It is serviced by a large number of airlines. Despite the name, Göteborg City Airport is less convenient to get to and from, since the airport bus runs less frequently. Its main advantage is that it is serviced by budget airlines, mainly Ryanair. See the Wikipedia pages linked to above for more airline and destination information.

3.1.2 Train

SJ has fast train connections to Stockholm, Oslo and Copenhagen, and overnight trains to other european destinations. The trains arrive at the Central Station, right in the city center.

3.1.3 Sea

Stena Line operates ferries from continental Europe along two routes. Fredrikshavn (Denmark) can be reached in 2h on a high-speed craft and in 3.15h on a car ferry. Kiel (Germany) can be reached in 14h. The terminals are situated near the city center.

3.1.4 Local transportation

The Landvetter Airport Bus stops at Korsvägen, where you can take trams 6 or 8 to Chalmers. Tram 7 takes you from the Central Station to Chalmers. See the map of the tram and trunk bus network for more information. The Chalmers stop is located somewhat below the center of the map.

3.2 Accomodation

The Hac4 map includes these accomodation options:

  • Nice Bed & Breakfast is also located close to Chalmers. Single rooms from SEK 425 per night, double 495, triple 695 and four bed room from SEK 995 per night.
  • Quality Hotel Panorama is located close to Chalmers. Single rooms from SEK 490 per night, and double rooms from SEK 840 per night.

4 When

The Hackathon will be held from 10am to 6pm each day, with dinner after at local venues.

5 Preparations

5.1 What to bring

  • A laptop
  • Wireless cards
  • Power adaptors if necessary
  • Mobile phone

There will be wireless network access. Ethernet access will probably not be available. If you really need ethernet access, please contact the organizers.

Power sockets in Sweden are CEE 7/4, delivering 230V at 50Hz.

5.2 Before you arrive

  • Pick out a couple of projects to work on and familiarise yourself with them
  • Install an up to date Haskell toolchain (preferrably ghc-6.8.2).

6 Projects to work on

Add ideas here for which you think hacking together as a group (rather than individually) would be beneficial. See also the more detailed projects page.

6.1 Group projects

  • Building tests that give 100% code coverage for package base.
  • Lots of Cabal hacking still to be done
  • Bindings for <your favourite C library>
  • Haskell library for <your favourite task>
