For new people

The DIRAC meeting is a family reunion for DIRAC developers and DIRAC friends. It is a nice opportunity to meet the people behind the DIRAC code. There is no registration fee but for organization purposes please add yourself to the participant list below (send an e-mail to Hans Jørgen using hjj at sdu.dk if you do not have editing permission to this page).

Most people will stay at the campground (more info below). The cabins are very good comfort, not expensive, and it's fun to be there. Book them well in advance.

We will discuss science but a significant part of the program is reserved to discuss the future of the DIRAC code, programming, code maintenance, release planning, as well as for programming task groups.

The meeting program is self-organised, simply add talks and discussion points to the program.

How to get to Odense

Typically you will fly to Copenhagen and then take the train or fly to Billund and then take bus to Vejle plus train Vejle-Odense. From Odense train station you can take bus 61 or 62 (in the right direction!) or share cab to the DCU-Camping Odense. If you arrive to Odense by train on a regular train ticket, then the bus from the railway station to the camp ground (or any other destination in Odense) is included in the train ticket.

Lodging

Make your cabin reservation at DCU-Camping Odense. The cabins can accommodate 3-4 people so organize with others. Use the dirac-developers mailing list.

A downtown hotel at the railway station: CABINN Odense Hotel. You can find other hotels from around 500 DKK per night by searching google for “hotels Odense” and some BBs to less than 500 DKK. Note that hotels might be cheaper via their own web site than on hotels.com etc.

Bus tickets

  • Fynbus web page is here. Notice that there is a Fynbus app.
  • Regular bus tickets for local travel in Odense cost DKK 24 in cash for a single ride (including changing lines) and are valid for 1 hour.
  • With the fynbus app it is the same price, but you will be able to pay with your credit card. The ticket must be bought before entering the bus and you show the ticket on your smart phone when you enter the bus.
  • Bus routes Railway station - campground (line 61-62)
  • Bus routes Railway station - university (line 41-44)
  • A map of all bus lines in Odense can be found here
  • Arriving by train to Odense on a regular train ticket (not discount “orange ticket” bought on http://www.dsb.dk/en/) you can use your train ticket for the bus and get a free ride (to the campground).
  • (Not recommended by Hans Jørgen, unless you plan to travel in Denmark regularly.) You can buy a public transport card (“Rejsekort anonymous”) valid in entire Denmark already at the airport in Copenhagen which you can charge and use for all train and bus rides. However it is quite expensive in start-up fee (110 DKK) + 600 DKK pre-paid to be able to use it for national travel (e.g. to CPH-Odense). In general, you have to charge it with enough money in a “Rejsekort automat” for any travel before the travel. As far as we can see you cannot get a refund of unused money. Furthermore, without a Danish address you won't be able to get receipt for the different travelled distances.http://www.rejsekort.dk
