The mobile sprint would be the first sprint with KDE on mobile in mind. The idea here is to put together people from different KDE's sub-projects to discuss about problems that affects them all when going to mobile platforms.


November, 18th - 21th

Location / Travel Information


We couldn't find a place or somebody to organize the sprint in a proper way in this city. Thanks a lot for the people that tried making it happen in Dublin, but it just got harder and more expensive than doing in Berlin. Let's try again Dublin the next time :(



Attention: KDAB moved since last time!

Tempelhofer Ufer 11
10963 Berlin
Phone: +49-30-5213254-70

Google Maps

Getting there by public transportation:

  • subway lines U1 or U6 to "Hallesches Tor"
  • subway lines U1 or U7 to "Möckernbrücke"
  • bus line M41 to "Hallesches Tor" (leaves from Berlin Hauptbahnhof)

Getting in:

  • If the big front door is closed, there is a door bell on the right, labeled 'KDAB'.
  • After passing the main gate, there are two options:
    • Take the stairs on the right, go up one floor, take the door on your right and go up one more floor. You'll find a door labeled KDAB in front of your with a door bell on the right (that one might need some more pressure to trigger).
    • Be lazy and go through the second big door right in front of you, turn right and take the entrance to the elevator on your right. KDAB is on the second floor.

Public Transportation

Some general notes on public transportation in Berlin. But the hostels are walking distance from the office anyway.

Reginal trains/S-Bahn/U-Bahn/Tram/Bus Tickets


Everywhere you need to go is covered by the 'AB' zone tickets, with the exception of SXF, for that you need one for the 'ABC' zone.

Buying Tickets

Tickets can be bought at ticket machines which you'll find at every station and the bus stop at TXL. On stations with long-distance connections you might find two types of ticket machines, use the ones labeled 'BVG' in black on a yellow square, not the ones labeled 'DB' or 'Deutsche Bahn'.

Ticket machines always take coins, and sometimes bills and ec cards (no credit cards IIRC).

Prices and Price Optimizations

Single trip costs 2.10€ in 'AB' zone and 2.50€ for 'ABC'. The ticket if valid for a single trip (including changing trains, as long as you go roughly into one direction) for all means of transportation listed above, ie. you don't need two tickets when switching from S-Bahn to U-Bahn for example. Tickets have to be stamped before entering the train once.

There are a number of optimizations though:

  • You can purchase a batch of four tickets at once ("4 Fahrten Karte"), which costs 8€ for 'AB'.
  • If you plan to do more than 2 trips a day, purchase the day ticket instead, 6.10€ for 'AB'.
  • If you do two trips a day with 4 or 5 persons, consider the group day ticket ("Kleingruppenkarte"), which costs 15.90€ for 'AB'.
  • If you only travel for three stops, there is the short trip ticket which costs 1.30€. This might be interesting in combination with the next option.
  • If you are traveling together with a local who has a monthly ticket, one additional person can tag along for free after 20:00 on workdays and during the entire day on weekends and public holidays.

Schedule can be checked online (see link below), which makes sense when traveling outside of the normal working hours on weekdays (where trains go every 5 minutes). During weekdays service ends at around 1am. On weekends, public holidays and nights leading up to those trains usually go all night but only every 15 or 20 minutes.

More Information

Local transportation in Berlin

Subway and railway map of Berlin


Taxi to TXL costs 20-25€.


There are currently two active airports in Berlin: Tegel (TXL) and Schönefeld (SXF). Make sure you know which one to go to, picking the wrong one has only happend to locals so far and you don't want to change that :)

TXL is not connected to any train line, but there is a shuttle bus (called 'TXL') leaving in front of the terminal building towards the city center.

SXF has a station for both regional trains (red 'B' on white square) and a S-Bahn line (white 'S' on green circle).

  • kdelibs modular (different profiles)
  • Results of the KDE Session on MeeGo Conference (KDE mobile UX, QtComponents)
  • Community OBS for MeeGo (easily provide packages)
  • Plasma bridge for QtComponents


  • Plasma's QML infrastructure easily reachable by other KDE apps (i.e. KDE PIM)


  • Plasma mobile
  • Other mobile platforms (non-meego)


  • Show off KDE on MeeGo (ideapad) - DONE
  • Common QML infrastructure in KDE (i18n, KICon, KConfig, etc..) - WIP
  • Qt-Components for Plasma - WIP
  • Decisions about next steps - WIP


  • we will attempt to get a real KDE space on OBS
  • the spec files for MeeGo will be maintained there, using OpenSuse as an upstream, where possible
  • the OBS will be undergoing maintenance over the next few weeks, so be patient with it :)



  • packages packages packages
    • who's doing that? what still needs doing? how fine-grained?
  • how do we make the image?
  • what exactly will the image contain?
  • what will the plasma shell be like?
  • style guide??
  • how do we promote this? (don't be smeegol)
  • what else needs doing?



  • check that our "discoveries" get into another sprints
    • ux meego (kde/distribution) sprint
    • design and interactions sprint (talk to seele and pinheiro)
    • plasma sprint
    • kde platform sprint (talk to aseigo)

Open Questions

  • will we have different KDE libs spins for the three profiles, on OBS?
