KDAB
Tempelhofer Ufer 11
10963 Berlin
Germany
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.

Hotel

Hotel Ibis Berlin City Ost
An der Schillingbrucke 2
10243 Berlin
Germany
Phone: (+49)30/257600 
Fax : (+49)30/25760333

Google Maps

Easiest way to reach the hotel is by taking a train to Ostbahnhof (it's just across the street from the station). If your train doesn't stop there, take the S-Bahn from Hauptbahnhof, any east-bound line will do.

From TXL take the bus labeld 'TXL' to Hauptbahnhof or Alexanderplatz and switch to the S-Bahn there, any east-bound train will do.

From SXF take the regional train 'RE7' or 'RB14' towards Berlin to station "Ostbahnhof" (2 stops, about 20 min).

Hotel <-> Office

Two options with public transportation:

• via Friedrichstraße
  • any westbound S-Bahn from Ostbahnhof to Friedrichstraße (4 stops)
  • U6 southwards (direction Alt-Mariendorf) until Hallesches Tor (4stops)
• via Warschauer Straße
  • any eastbound S-Bahn from Ostbahnhof to Warschauer Straße (1 stop)
  • U1 westwards (there is only one direction, the station is the terminus for U1) to Hallesches Tor (5 stops)

Or take a taxi, possibly even cheaper when shared with enough people.

Public Transportation

Some general notes on public transportation in Berlin, more relevant this time with hotel and office not in walking distance from each other.

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

Zones

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

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.

Taxis

Taxi to TXL costs 20-25€, taxi between office and hotel around 10€. So, if you order a big one this might actually be the cheapest and most comfortable way to travel between office and hotel.

Airports

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).

Meeting Notes

KOrganizer Refactoring Plan

Make reusable components out of KOrganizer for reuse in the mobile applications, initial draft based on KOrganizer meeting from April 12th. Current status in square brackets.

Incidence Editor

eventually used in: KOrganizer desktop and mobile, invitation BPF plugin, korgac, summary view, plasmoids

• To make it independent from KOrganizer we need at least:
  • split up preferences [done]
  • get rid of interfaces/incidencechangerbase [done]
  • move incidencechanger to kcal_next [done]

• For mobile we need:
  • new fb view, see below [Bertjan volunteered to investigate that]
  • ui'ify [in progress, Bertjan]
  • get rid of Qt3Support usage [done excpet for fbview]

• Bonus points for:
  • remove code duplication between eventeditor, todoeditor, journaleditor

Free/Busy and Timeline view

Write a new freebusy graph widget (libfbview) that can also be used in timelineview

Still unsure which option is best:

• use and extend KDGantt2
• write a entirely new view, possible reusing some of the rendering and layouting code from month/agenda view

[Bertjan volunteered to investigate that]

Incidence Viewer

• eliminate duplication between KOrganizer and akonadi/kcal, necessary since korgac depends on the koeventviewer.

[Tobias volunteered to look into this]

Views

Plan

Make views independent from KOrganizer

• kdepim/libeventviews
  • move all non-todoview views here
  • move interfaces/baseview.h here
  • move view kcms here as well

• kdepim/libtodoviews
  • move todoview here
  • shouldn't need baseview.h
  • anything reusable in/for zanshin here?

• remove Qt3support

Current State

• agenda view extracted
  • Qt3Support removal complete
  • Decorations are still disabled
  • KOrganizer still has its own copy
    • to be ported after 4.5 branching
    • Sergio monitors commits and merges them between the two copies if necessary
    • Porting KOrganizer requires porting the multi agenda view away from Q3ScrollArea as well

• month view
  • Sergio says it's much easier to do

• timeline view
  • see above, requires a rewrite

• todo model/view
  • Sergio says it's easy
