Hac5: The 5th Haskell Hackathon
April 17-19, 2009 Utrecht, The Netherlands
The Haskell Hackathon is a collaborative coding festival with a simple focus: build and improve Haskell libraries, tools, and infrastructure. Of course, we have fun doing it, too!
The 5th Haskell Hackathon will be held from April 17 to 19, 2009, in the city of Utrecht in the Netherlands. This year's event is being organized by members of the Department of Information and Computing Sciences at Utrecht University and by associates of Tupil.
- 2009-02-11: The date has been picked.
Check out the possible projects that you might work on or add your own.
If you will be attending, please register. The number of attendees may be limited, depending on availability of space or other resources.
See who else is attending. If you've already registered, please add yourself to the list.
- April 17-19 2009
If sufficiently many participants are already around on April 16 or are still around on April 20, a small symposium and/or an excursion could be organized.
7.1 Getting there
- Schiphol Airport (AMS) is the main airport of the Netherlands. There is a train station right underneath the airport, and every 15min there is a direct train to Utrecht.
- The airport in Eindhoven (EIN) is cheaper than Schiphol, so many low-cost airlines fly there. There is a bus terminal outside the airport which will take you to Eindhoven station.
- International trains (UK, France, Belgium, Germany)
- National trains
- General information
- NS is the main public transport railway company in the Netherlands. You can buy tickets on machines at the station (you can also practice this online). Maestro Debit cards are usually accepted and credit cards should work too, but in practice I've seen many people having trouble with this.
- If you pay with cash you have to go the counter, where you'll be charged extra for the ticket.
- From Schiphol, trains depart to Utrecht every 15min. The ticket price is €7,80 (second class, full-fare, one-way). The trip takes about 30min.
- From Eindhoven Airport, first you have to take bus 401 to Eindhoven station. There is a ticket machine inside the bus but you will need (Euro) coins to pay. Then from Eindhoven station you can take the train to Utrecht. There are trains every 15min to Utrecht Centraal. The ticket price is €12,80 (second class, full-fare, one-way). The trip takes about 50min.
- General information
- Arriving at Utrecht Central
- Outside the train station in Utrecht is the main bus station. From there you can take buses number 11, 12 or 12S to the University. The trip takes about 20min and takes 3 'strippen'.
- Pier "Hoek van Hollland"
- From Hoek van Holland you can take the train to Rotterdam (Centraal), and from there to Utrecht. The train station is located just next to the pier. The trip takes about 1h20 and costs €13.30 (second class, full-fare, one-way). You don't need to buy any ticket in Rotterdam, you can just buy a ticket from Hoek van Holland to Utrecht.
7.1.4 Local transportation
- Public transportation
- To travel by bus, tramway or metro in the Netherlands, you're advised to buy your ticket in advance. This ticket is called a 'strippenkaart'. Strippenkaarten of 15 or 45 strips are available for €7.30 and €21.60 respectively, and one trip on the bus within a city (including all transfers within 60 minutes) is usually 2 or 3 strips of the card. Most places within the city center of Utrecht are one zone away from the zone where Utrecht University is located, hence you use 3 strippen for this trip.
- Typically you enter the bus through the front door and tell the driver where you want to go. He then stamps the appropriate number of stripes from your strippenkaart. However, in some cases the bus driver might open all the doors and assume people will stamp the tickets themselves (this will typically happen for buses 11 and 12 during rush hour). You can then use the yellow (or nowadays grey) stamp machines inside the bus or at the station just before you depart.
- Buying tickets on the bus is far more expensive. You can get these multiple-strip-/zone-tickets-card(s) in many places, including bus stations, post offices, cigar/magazine shops and some supermarkets (at the service desk or from a vending machine). You can use it also for multiple-party travel for yourself and other persons at the same time. You can read more about the strippenkaart in the ov-info website.
- By bike
- Biking is a very convenient way of traveling inside a city in the Netherlands. In particular, the way from Utrecht central station to the University is mostly through separate bike lanes and takes about 20 minutes. You can rent a bike from one of 3 bike parking areas at the station. The daily fee is €6.50 and you have to pay a deposit of €60 and show proof of identity (either driver's license or passport). (Note that these are not "OV-fiets"---those require a yearly subscription.) These places are open from 5am to 2am, every day of the week.
- Make sure to obey traffic lights for bikes as being fined for not doing so is very common. You should also have your front and rear lights on when biking during nighttime (a rented bike will most probably have these in working condition). Also be careful where you park your bike and always lock it securely, since bike theft is very common in the Netherlands.
It's not always easy to find loads of choice in accommodation in Utrecht. In particular, the Hackathon weekend coincides with a record fair. So you should try to make your room reservation as soon as possible.

You can also have a look at hotels.nl. They seem to have availability for some of the places which told us they were fully booked.
If you have any doubts about any place, for instance about how easy it is to reach the University from there, just ask the organizers.
There is also an annotated Google Map with important locations.
9.1 What to bring
- A laptop
- Wireless card if necessary. There will be wireless network access. Ethernet access will probably not be available. If you really need ethernet access, please contact the organizers.

9.2 Before you arrive
- Pick out a couple of projects to work on and familiarise yourself with them
