The German Community Meeting takes place at the same time: https://wiki.documentfoundation.org/DE/Community-Treffen2018

The LibreOffice Hamburg HackFest 2018 will take place on the weekend of April 6th-8th 2018, at freiheit.com, Budapester Strasse 45, Hamburg.

About the location


From last years description:

The city of Hamburg has throughout history taken its freedom and independance as a high treasure -- as can be seen from the motto: "Libertatem⁠Wikipedia logo v3.svg quam peperere maiores digne studeat servare posteritas". It is also the closest major city to the birthplace of the codebase that later became LibreOffice. We will meet at freiheit.com, Budapester Strasse 45, Hamburg . Hamburg is rumored to have one of the worst climates of Germany (constant low-intensity rain), but in April the weather could be nice and warmy - or it could be all cold and rainy. We will see ;-)


If there is a pet bug/feature you are interested to solve/create on the Hackfest add it here and we will try to find a mentor giving you guidance. Also if there is a general topic you want to cover/have a short talk about, add it here.

"topic/bug/feature interested hacker(s) mentor/speaker
Make LibreOffice able to use the <draw:layer-set> element directly from all three possible locations in content.xml and styles.xml, without using application specific information in settings.xml.

(Thereby learning more, what happens on the way from file open to rendering.)

How to get there

Location at OpenStreetMap: https://www.openstreetmap.org/node/5252500308#map=19/53.55529/9.96426

Street address: Budapester Strasse 45, Hamburg

Public transport

  • from Hamburg airport:

Take the subway S1 (green line) to Barmbek. In Barmbek change to U3 (yellow line) direction Schlump. Exit at "U Feldstrasse". Walk to Budapester Strasse 45. Note the U3 (yellow line) is running a circular track from Barmbek to Barmbek. The downside is choosing the right direction might be a bit more confusing, the upside is, even if you pick the wrong direction, you will likely arrive at your destination -- if only on a bit of a detour.

  • from Hamburg central station:

Take U3 (yellow line) direction Barmbek (via Schlump). Exit at "U Feldstrasse". Walk to Budapester Strasse 45.

If you plan to stay all three days, it pays off to grab a 3-day ticket (3-Tage-Karte). When staying less than 3 days, if you plan more than 2 rides a day, buy a 9 o'clock day pass (9-Uhr-Tageskarte) after 9:00 for the Greater Hamburg Area (Großbereich). Note that with single tickets (Einzelkarte), round or return trips are not permitted.

Subway and light railroad runs every 20 minutes the entire night during weekends.

See the Hamburg public transport pages for details.

  • StadtRAD Hamburg (public bicycle system)

If you are already a customer of the Deutsche Bahn Connect / Call-a-Bike system, you can use the red StadtRAD bicycles. The first 30 minutes of each ride are free (regardless whether you have a BahnCard or not), which is plenty of time to reach the next 5 bike stations and switch bike.. or pay 8ct/min after that.

See the StadtRAD Hamburg website for stations and conditions. It may even be worth to register as a new customer, it costs 5€ (serving as deposit) by SEPA direct debit, or credit card. Having registered with StadtRAD you'll also be entitled to use the Call-a-Bike system in other German cities (though they don't have the "first 30 minutes free" regulation).

By car

It's a downtown area with very little if any parking space at evenings, so plan for some time to find a spot (and walk back). Be advised that Hamburg authorities are rather strict in towing away cars not properly parked, they're especially quick if fire exits or access roads are blocked.


We would like to thank our following sponsors and supporters for making the Hamburg Hackfest possible:

  • freiheit.com technologies for generously hosting us!
  • Hamburg-based LibreOffice hackers, for offering couch surfing
  • The Document Foundation, for providing travel sponsoring


Recommended Hotels close to the location:

Please contact the Hackfest organizers before booking: It is much better to have us share one hotel (e.g. for the evening) instead of being distributed over many!

Local LibreOffice hackers will provide (limited) couch surfing capabilities, which will be handed out on a first-come-first-served basis. Please contact the organizers if you're interested - both for offering and requesting couch surfing.

Travel Bursaries

The Document Foundation may be able to refund tickets to and from the Hamburg Hackfest, after prior approval by the organizers, under the following conditions:

  • transportation-only, please sign-up for couch surfing if you need free accommodation
  • volunteer-first - people affiliated with a company involved in LibreOffice work will come last
  • first-come-first-served - participants will get reimbursed in order of their sign-up on the wiki attendance list, until budget runs out.
  • ask the organizers as soon as possible (ideally right before booking) if budget is still available. Be aware of the fact that tax law requires us to collect original receipts, so please keep them (or hand them in right there in Hamburg)

Please be economic and pick cheap travel - that said, flights to Hamburg might still be available at a reasonable price.

For those who attended: If you'd like to request a travel reimbursal, please follow the HowTo at TDF/Policies/Refunding for the SPI refunding, and mail treasurer@documentfoundation.org with your documents.
