== Fund Raising ==

The fund raising at OctConf yielded a <b>$700</b> donation for GNU Octave on Oct 2, 2015 (Transaction ID

[[File:mathildenhoehe2.jpg|300px|thumb|left|alt=Mathildenhöhe in Darmstadt|Mathildenhöhe in Darmstadt]] 
=== Darmstadt, Germany ===
Darmstadt is a medium sized German city (154.002 inhabitants, cf [http://www.darmstadt.de/fileadmin/Bilder-Rubriken/Standort/Statistik_und_Stadtforschung/pdf/faltblaetter/ZahlenInKuerze2015-internet.pdf http://www.darmstadt.de]) located in the close neighborhood to Frankfurt, i.e., easy to reach due the airport [http://www.fraport.com/en.html FRA]. It is one of the few cities in Germany that are allowed to call themselves "city of science". The reason is that Darmstadt has clearly dedicated itself to academia and research:, it has a technical university ("TU Darmstadt", founded in 1877) and two universities of applied sciences "h_da" and "Evangelische Hochschule" with 40,616 students in total. Furthermore there are several research institutes, e.g., the [http://www.esa.int/About_Us/ESOC European Space Operations Centre], [http://www.eumetsat.int/website/home/index.html EUMETSAT] and the [https://www.gsi.de/en/start/news.htm GSI Helmholtz Centre for Heavy Ion Research], which discovered with their heavy-ion accelerator chemical elements like [http://en.wikipedia.org/wiki/Darmstadtium Darmstadtium]. Many technology companies are also located here, e.g. big cooperations like [http://www.telekom.de/ Deutsche Telekom], [http://www.merck.de Merck] but also SMIs like [https://www.cst.com CST] which is a spin-off of TU Darmstadt and the market leader for high-frequency electromagnetic field simulations.

In former times Darmstadt was the seat of government of the German State [https://english.hessen.de Hessen] and thus has still an active cultural life and in particular important architecture from the beginning of the 20th century. The [http://en.wikipedia.org/wiki/Ernest_Louis,_Grand_Duke_of_Hesse dukes of Hesse] were at that time interested in art, in particular the so-called Jugendstil (the German version of [http://en.wikipedia.org/wiki/Art_Nouveau Art Nouveau]) and funded the [http://en.wikipedia.org/wiki/Darmstadt_Artists%27_Colony Darmstadt Artists' Colony]. It is still located at the [http://www.mathildenhoehe.eu Mathildenhöhe].

=== Venue ===
The upcoming Octconf 2015 will take place at the Graduate School of Excellence Computational Engineering (CE) at the Technische Universität (TU) Darmstadt 

Graduate School CE<br>
[http://www.openstreetmap.org/#map=18/49.87756/8.64091 Dolivostraße 15]<br>
D-64293 Darmstadt

[[File:gsce.jpg|160px|thumb|riht|alt=Graduate School of Computational Engineering|Graduate School CE]]
The institution has been recognized as a center for top-level research and scientific excellence by the highly competitive 'Excellence Initiative' of the German Federal and State Governments. The Graduate School enables PhD students to develop their scientific skills in a focused way, and to cooperate under optimal conditions in a highly stimulating interdisciplinary environment (computer science, engineering and mathematics). One lecture hall and two seminar rooms with wifi ([https://www.eduroam.org eduroam]) are reserved for the whole week.

=== Travelling ===
You can find travel directions [http://www.graduate-school-ce.de/index.php?id=23 here]. The recommended procedure is a flight to [http://www.frankfurt-airport.de/content/frankfurt_airport/de.html Frankfurt's International Airport] and then taking the bus called "[http://www.rmv.de/linkableblob/de/33548-59802/data/AirLiner_Direktbus_Darmstadt_Frankfurt_Flughafen_PDF.pdf Airliner]" to Darmstadt main station. [https://www.hahn-airport.de/Default.aspx?menu=passengers_visitors&cc=en Frankfurt Hahn] is also an option but is approximately 130 km away from Darmstadt and there is no direct connection. To get from Hahn to Darmstadt the best way is to take the [http://www.bohr.de/linienverkehr/buslinie-hahn-frankfurt bus to Frankfurt Hbf], get off at Frankfurt's International Airport stop and take the "Airliner" from there. The conference hotel (see below) is directly at the train station and the venue in 15min walking distance.

We have prebooked rooms in
* 15 single rooms in the [http://en.intercityhotel.com/Darmstadt/InterCityHotel-Darmstadt InterCityHotel Darmstadt] (booking via e-mail or phone is recommended; code "TU Darmstadt, Octconf 2015) 
   Email address is:  reservations@darmstadt.intercityhotel.de
* 2 rooms in the [http://www.djh-hessen.de/jugendherbergen/darmstadt/ youth hostel Darmstadt]

== Dates ==
September 21-23, 2015. This is from Monday to Wednesday. Participants are encouraged to attend for all three days, but anyone is welcome for any duration of time. If necessary, invitation letters can be issued.

Excursions for the technology enthusiasts to ESOC, EUMETSAT and/or GSI are planned.

== Suggestions for Sessions ==
Code sprints and informal discussion will happen every day. Please propose topics of interest for these sessions.

== Child Care ==
TU Darmstadt is a family friendly university. If you are planning to attend OctConf with your family/children please contact us. We will be happy to help you to organize child care.

== Funding ==
There is limited funding to cover the travel expenses of selected participants. The available funds have currently been assigned.

The following institutions have provided funding so far:

* the [http://www.graduate-school-ce.de/ Graduate School CE] has granted travel funds for invited speakers
* the Institute [http://www.temf.de Computational Electromagnetics Laboratory TEMF] offers further sponsoring, e.g. for travel grants
* the [https://www.cst.com CST – Computer Simulation Technology AG] will financially support event (Catering, Coffee breaks etc)

== Questionnaires results ==

* All participants are compilers of Octave themselves.The main reason for them to participate to the conference is their interest in the development of Octave Core. Besides that also meeting the other developers in real life seems to be a motivation to join.
* The desired timespan for the conference is for almost all the participants 3 days.
* The amount of talks was to all participants adequate.
* 43% of the participants would like to have more code sprints for 57% the amount of sprints were adequate.
* Everyone liked the excursions, however 4 out of 14 participants thinks that the amount was too high.
* The poster session was appreciated by all participants and there is a slight request to extend it.
* There is also a request to define specific goals before the conference. The most proposed tool to share those goal is the wiki.
* About the financing of the conference: 8 of 14 participants do not care where the money is coming from. For those who care, they want the contribution of the conference fees to the financing as low as possible. For the other contributions there is no clear line.
* 10 out of 14 participants loved t-shirts and half of them thinks that we should stuff like this.
