Logistics

Approaching Karlsruhe

Karlsruhe is on the Rhine in Baden-Württemberg in Germany. It is in the north of the Black Forest, close to the French border.

• Baden Airpark (FKB) is the nearest local airport, about 40 km from the city. The airport is now served by low-cost carrier Ryanair, which offers cheap flights to several European destinations. There is a cheap airport shuttle bus (Baden Airport Express) (leaving 8 times a day on weekdays, 3 times a day on Saturdays, synchronized with the flight schedule) to Karlsruhe Hauptbahnhof (Karlsruhe Main Station). One-way tickets can be bought from the driver (9 EUR, cash only, accepted currency is EUR); alternatively, you can take a train or a tram-train to Rastatt or Baden-Baden and take a connecting bus to Baden Airport. Through-ticketing is available, for current prices and schedules see Karlsruher Verkehrsverbund (Karlsruhe Area Mass Transit Authority).

• Frankfurt Airport (FRA) is Germany's biggest airport and is served by all major carriers that operate in Germany. It has a direct ICE high speed train connection to Karlsruhe (60 minutes).
• Stuttgart Airport is reachable by train in 90 minutes.

• Frankfurt Hahn Airport (HHN) is about 200 km from the city and reachable by car, or a combination of train and bus. The airport is served by Ryanair and other low-cost carriers. To get to the airport with public transport you need to take a train to Heidelberg, Mainz, or Frankfurt -- there you can catch a bus to the airport.

• The train station is located south of the city center, with roughly 5-10 minutes by tram to the central market square, and direct tram links to other parts of the city. Karlsruhe is well-linked to other larger cities by ICE high speed trains. The schedules for the inter-city connections can be found on the site of the Deutsche Bahn (German Railroads).

• The bus station is located at the south entrance of the train station. You can buy tickets for international destinations inside the train station.
• Arrival by car:
  • From the A5 (Frankfurt): Karlsruhe-Mitte exit.
  • From the A8 (Stuttgart): onto the A5 towards Frankfurt.
  • From the Karlsruhe-Mitte exit: Stadtmitte/Staatstheater/Kongresszentrum turn-off (also from the A65).

Approaching Best Western Queens Hotel

The conference place and the primary accommodation (Best Western Queens Hotel) is next to the Karlsruhe Zoo has a tram stop right in front of it, and is a five-minute walk from the Main Station.

Approaching Karlsruhe Institute of Technology

Karlsruhe has an excellent public transport system. You can ride Tram #2 from Best Western Queens to "Durlacher Tor" and have a two-minute stroll to the University Building. 5 people can share a 24-hour "CityPlus" Ticket for 7.40 EUR that can also be used for going out in the evening. That is 3 EUR per person for transportation for the two days. Trains run every 10 minutes during the day (till at least 8:00 PM) then every 20 minutes (till around midnight) and then selected trains every 1 hour.

The event was on the campus of the former University of Karlsruhe (TH), now part of the Karlsruhe Institute of Technology. The campus is located next to the central building of Karlsruhe, the Karlsruhe Palace. The booked rooms were in building number 50.34 (street address: Am Fasanengarten 5).

Schedule

(KIT = Karlsruhe Institute of Technology)

The developer summit span two days, with a mixture of presentations, hacking, and working group meetings. We had room for up to 6 sessions at once on both days, although "talks" were reserved for the mornings and "discussions"/"hacking" for the afternoons. We primarily counted on short talks of maximum 15 minutes (a 5-minute presentation followed by 10 minutes of discussion) to keep things moving but having flexibility to allow discussion to run on as needed, with the possibility of a dedicated session in the afternoon.

We reserved 4 rooms at Karlsruhe Institute of Technology for the developer summit, all of them were available between 9 AM and 6 PM on both days.

Thursday 7 October 2010

Friday 8 October 2010

Registration

REGISTRATION HAS NOW CLOSED. A registration fee was charged for all attendees in order to cover snacks and beverages served during the sessions. The fee was 30 EUR on October 7 covering both days, and 15 EUR on October 8 covering only that day. The fee was to be paid in cash on site when checking in.

Lunches and dinners were paid on individual basis, but all the places were booked in advance. Here is a list of the attendees and their guests at the summit. (BWQ = Best Western Queens Hotel)

Developers were welcome to invite guests to attend the developer summit, subject to their tolerance for ceaseless hours of kernel hacking, and availability of space at the venue.

Proposed Topics

Here is a brief listing of various proposed topics were presented and partially discussed at the summit.

Note to Leaders

If you were in trouble with preparing your slides, you could use the template attached to the page. It contains a LaTeX source file that you can modify to create PDF slides for the FreeBSD Developer Summit. It uses the Beamer class which is an easy-to-use extension to LaTeX for making presentations. You can easily install it by the following command (as root):

# pkg_add -r latex-beamer

This will install Beamer and pdfLaTeX that can be used for compiling the sources to produce the desired PDF file.

$ pdflatex my-presentation.latex

A few rule-of-thumbs when creating slides:

• Try to make things legible, use large fonts.
• Have title and closing.
• Use less text, you do not have to include everything on the slides. (Prepare and) Do a demonstration if needed.
• You have only 5 minutes, having only 5 slides (in addition to title and closing) is usually fine.
• Sometimes images can tell more than pure text.
• Discussions and meetings are the place where you might want to talk about the details.

Contact PáliGáborJános if you have questions or problems.
