The Dutch Haskell Users Group is hosting a combined event for Haskell enthusiasts: an informal mini-conference and a weekend hackathon. It is the Dutch HUG Day followed by Utrecht Hackathon, or more concisely ...

Event: DHD >>= UHac
Dates: April 20 - 22, 2012
Location: Utrecht, The Netherlands

1 Introduction

The DHD and UHac are two events held over a long weekend and organized by the Dutch HUG.

NOTE: Everything regarding the DHD >>= UHac is in English!

1.1 Dutch HUG Day

Dhug2.png The DHD will be on Friday, April 20. We invite people from all backgrounds to speak about their hobby projects, their research, or anything else related to functional programming.

This will be the second time the Dutch HUG has hosted such an event. The first Dutch HUG Day was held on April 24, 2010. It was a great success and brought together people from all over the Netherlands, as well as Germany and Belgium.

We intend to make this year's DHD just as successful and open it to an even wider audience by binding it to a hackathon, which usually attracts people from all over Europe.

1.2 Utrecht Hackathon

Hac-axe-icon.png UHac immediately follows the DHD and lasts from Friday, April 20, to Sunday, April 22. In the now-grand tradition of Haskell hackathons, UHac is an international, grassroots collaborative coding festival with a simple focus: build and improve Haskell libraries, tools, and infrastructure.

Haskell hackathons have been held every year since at least 2006. Utrecht hosted its first hackathon, Hac5, in 2009, and this is the second.

1.3 Dutch Haskell Users Group

The Dutch HUG is an informal group with monthly meetings. Each meeting often includes talks on novel applications of functional programming. Other times, members just gather for drinks at a pub. The group was founded on April 19, 2009, at the end of Hac5. In April, 2012, the group celebrates its 3rd year of existence.

2 Schedule

We have combined two events in the hopes that people interested in one might also take the opportunity to check out the other. Thus, it's much easier if the events are juxtaposed. In that light, here is a preliminary schedule to help you plan your time here.

Date Time Event
Friday, April 20 9:30 - 15:30 DHD at Ordina (venue, program)
16:00 - 20:00 UHac at Newton (venue)
Saturday, April 21 9:00 - 19:00 UHac at Newton (venue)
Sunday, April 22 9:00 - 19:00 UHac at Newton (venue)

3 Registration and Attendees

Registration allows us (the organizers) to determine the number of participants (for logistics such as seating, lunch at the DHD, and rooms for UHac) and gives us a means to contact them. Please register:

Registration deadline for the DHD: April 1, 2012
Registration deadline for UHac: April 19, 2012

In addition to registering, it is often helpful to arrange things (such as accommodation, transportation, etc.) with other participants. Please include some information about yourself in the list of attendees, so that others may contact you to coordinate.

4 Local arrangements

Refer to the local information page for the latest on everything related to the location.


See the program page for details.

6 UHac

6.1 Project information

Have plans for a project to work on during UHac? Want to find out about other people's projects? Check out the project page for details.

6.2 Rooms

We have two rooms for UHac, and one of those rooms will support tutorials and presentations (and anything else that requires a projector or group meetings). See the rooms page for more information.

7 Discussion and social


Join the official #uhac channel on


Use the mailing list to communicate broadly with other hackathon attendees.

Join the mailing list to chat with other Haskell hackers in the area of the Netherlands (and even occasionally Belgium and Germany). The Dutch Haskell Users Group meetings are announced on this list. Most communication is in English, since there are a number of foreigners involved.

Hash Tags

8 Sponsors


We are extremely grateful to Ordina for hosting the Dutch HUG Day on their premises and for providing lunch to the participants. This is the second time they have hosted the DHD.
