    Tokamak 4 Oxygen 3 2010

    The fourth Tokamak Plasma Meeting and the third Oxygen Gathering will take place in Nuremberg, Germany on February 19th to 26th.


    We will be hosted by Novell in the openSUSE offices in Nuremberg. The community space includes a large meeting room with AV infrastructure, a cafe-style area and a hacking bar. And of course you benefit from being only metres away from the KDE SVN server.

    Nuremberg is easily reachable by air or by train. The nearest airports for intercontinental flights are Frankfurt and Munich, and Nuremberg is served from other European hubs such as Paris Charles De Gaulle and Amsterdam. Nuremberg is only a few hours by train from most of the rest of central Europe.

    You can reach the SUSE office in 6 minutes by tram from the rail station by taking the number 8 tram towards 'Thon' from the tram interchange in front of the railway station, follow the square 'Tram' signs. Alight at 'Maxfeldstr' as shown on the signs inside the tram and go to the SUSE office at Maxfeldstr. 5.

    From the airport, a taxi will cost 10-14 EUR and takes about 10 minutes. Alternatively, take the U2 metro from outside Arrivals (any train), alight at 'Rennweg', leave the station by the south exit (in the direction of travel, go to the tram stop in the middle of the road on your right as you exit the metro, and get the number 8 tram towards 'Thon' as above.

    Public Transport

    Nuernberg has a pretty good general public transport information site that covers bus, tram, local trains and underground/metro with some info in English: Nuernberg public transport information. A single journey costs 2EUR, a 10er strip costs 9.20EUR. Buy tickets from multilingual touchscreen vending machines before you get on the bus/tram/underground, and single tickets are already validates. A 10er strip needs stamping, 2 units per single journey for an adult.

    Airport -> BFW

    You probably don't want to do this if you are tired after a long flight. Although it is short and easy you have to find the right stop for the 26 at the interchange at Thon. A taxi cab will be under 10EUR. About every half an hour until midnight:

    Get the 32 bus towards Thon, get off at Thon (last stop). Then get the 26 bus towards Berufsförderungswerk (last stop). This drops you at the entrance to the BFW, take the side entrance to the Gaestehaus.

    BFW -> Airport

    Get the 26 bus towards Thon, get off at Thon (last stop). Then get the 32 bus towards Flughafen (the airport, the last stop).

    BFW -> SUSE

    Get the 26 bus towards Thon, get off at Thon (last stop). Then get the 9 tram towards Doku-Zentrum. Get off at Maxfeldstr. The SUSE building is the large blue building on the right.

    BFW -> Rail station

    Get the 26 bus towards Thon, get off at Thon (last stop). Then get the 9 tram towards Doku-Zentrum. Get off at Maxfeldstr. The SUSE building is the large blue building on the right.

    SUSE (or Rail station) -> BFW

    Get the 9 Tram towards Thon, get off at Thon (last stop). Then get the 26 bus towards Berufsförderungswerk (last stop). This drops you at the entrance to the BFW, take the side entrance to the Gaestehaus.

    Get the U2 Underground (only one direction, Röthenbach). Get off at Opernhaus. Walk to Weidenkellerstr. 4 (see map above and hotel website).

    Hotel Astoria -> Airport

    Walk to Opernhaus underground, get the U2 Underground toward Flughafen (every 2nd train goes to the airport and have an aeroplane symbol on the destination board).

    Astoria -> SUSE

    Either print out the map and address, and walk through the city center (about 10 minutes), or get the U2 toward Flughafen or Ziegelstein, get off at Hauptbahnhof, follow the signs towards Tram at street level, get the 9 Tram towards Thon, get off at Maxfeldstr. The SUSE building is the large blue building on the right. (every 7 or 15 minutes until midnight, about 20 minutes)

    SUSE -> Astoria

    Get the 9 Tram towards Doku-Zentrum, change at Hauptbahnhof, get the U2 towards Röthenbach, get off at Opernhaus.

    Special Needs

    • Laptop/desktop for hacking with KDE trunk on it for: Lukas Appelhans
    • Helpful for hacking on the 3 Intel devices (not vital, but would preed thing up especially the ethernet adaptor):
      • usb hub (preferably powered)
      • usb-to-ethernet adaptor (unreliable drivers for the internal wifi)
      • extra storage/file transfer can be done with the ethernet adaptor of with microsd/thumbdrives
      • usb keyboards and mice would ease things a bit too since it supports them
    • For presentations a video camera would be nice, preferably with a remote microphone. (available in openSuse offices?). (It would be wonderful for those of us that cannot attend, so don't please don't forget us ;-) -sreich).


    We will be focusing on the KDE SC 4.5 release of Plasma, with a particular attention on feature completion, polishing and quality improvements across the code base. Activities and Plasma Mobile will also be topics of interest.

    Oxygen, finishing it up for 4.5 plans for the future.

    • Plasma netbook: State and road ahead - most important work still to be done (Marco Martin)
    • Context: [Details later] (Chani and Ivan)

    • Plasma OSD service
    • GSoC
    • application dashboards using View/Corona/Newspaper

    • javascript test coverage

    Breakout Groups

    Starting on day two we will split up into small groups to focus on specific topics and challenges. The breakout group tracks will start with short presentations designed to share important information about the topic of interest to get everybody up to speed. A schedule for each of the presentations will be posted closer to the start of Tokamak 4.

    Some people will stay with a specific track for the duration of Tokamak 4, but everyone is welcome to drift between the different breakout groups to bring their needs and ideas to bear.

    Plasma Mobile

    Plasma shells on devices with small screens and designed for mobility. The focus use case will be touch screen driven smartphones.
