One year of open governance for OTB: thoughts and context

Manuel Grizonnet
One year ago, in the frame of the OSGeo incubation process, OTB team decides to initiate a Project Steering Committee to formalize the way that decisions are taken. It was largely inspired by existing governance in other OSGeo projects related to OTB like GDAL, Quantum GIS or GRASS. This initiative aims in encouraging people and organization to join the effort and participate more actively in the evolution and the decision process of the library. Most...

Call your NetBSD

Pierre Pronchery
After focusing on improving NetBSD support for tablet hardware, NetBSD enthusiast and DeforaOS developer Pierre Pronchery (khorben@) is working on running NetBSD on smartphone hardware, with the OMAP-based Nokia N900 as the main target. After a quick summary of the different steps taken, he will introduce the user interface, installation procedure and underlying specificities to this setup. If all goes well, he will even be able to give a call! NetBSD is a very portable...

Videos in Public Libraries

Tilman Scheel
Providing access to video can be challenging, especially when it comes to film. To clear the rights, to get hands on the material, to manage the licenses, different language versions and age ratings - all this needs to be solved before a film is shown to any kind of public. More often than not, public institutions do neither have the expertise, the personnel, the money or the experience to answer to this challenge. The solution...

Jenseits von Mercator

Christoph Hormann
Karten im OpenStreetMap-Umfeld werden fast immer in Mercator-Projektion produziert. Diese prägt durch ihre Verbreitung nicht nur in OpenStreetMap, sondern auch in so gut wie allen anderen globalen Internet-Kartendiensten unser Verständnis von Geographie und Kartographie in einem erheblichen Ausmaß. Dieser Vortrag erläutert die Vor- und Nachteile dieser Projektion, insbesondere auch den Einfluss, den diese auf die Datenerfassung in OpenStreetMap hat. Es werden verschiedene Alternativen mit ihren möglichen Anwendungsfeldern vorgestellt sowie die praktischen Schwierigkeiten beim Umgang mit...

Otti Csaba: Security in our hands (?)

András Fehér, Sándor Kapitány & Dániel Martinkovics
A kézgeometria azonosítás egy széles körben elterjedt és használható technológia, amely bizonyos esetekben hatékonyan képes helyettesíteni a környezeti körülményekkel szemben kevésbé ellenálló társait, ugyanakkor kevesen tudják csak azt, hogy valójában hogyan muködik. Élo bemutatónk keretében megvizsgáljuk a technológia elonyeit, hátrányait, felfedjük sebezhetoségeit, és olyan támadásokat hajtunk végre, amelyek túlmutatnak magán a technológián.

Advanced Database Programming with Python

Marc-Andre Lemburg
Marc-Andre Lemburg - Advanced Database Programming with Python The Python DB-API 2.0 provides a direct interface to many popular database backends. It makes interaction with relational database very straight forward and allows tapping into the full set of features these databases provide.

How to GIS with Python

Anders Lehmann
Anders Lehmann - How to GIS with Python In this talk I will present some tools for working with Geographic Information Systems in Python. Geographic information Systems are widely used for managing geographic (map) data. As an example I will present how to use Open Street Map data, in routing, traffic planning and estimation of pollution emission. For the purpose of the project EcoSense, GPS data from users smartphones are mapped to OSM roads. The...

3/3 Lagrangian Floer cohomology in families

Mohammed Abouzaid
We will begin with a brief overview of Lagrangian Floer cohomology, in a setting designed to minimise technical difficulties (i.e. no bubbling). Then we will ponder the question of what happens to Floer theory when we vary Lagrangians in families, which we will not require to be Hamiltonian. We will see rigid analytic spaces naturally arise from such families; these spaces are the analogue of complex analytic manifolds over the Novikov field. In order to...

Trade-offs in Statistical Learning

Quentin Berthet
I will explore the notion of constraints on learning procedures, and discuss the impact that they can have on statistical precision. This is inspired by real-life concerns such as limits on time for computation, on reliability of observations, or communication between agents. I will show how these constraints can be shown to have a concrete cost on the statistical performance of these procedures, by describing several examples.

Paleomaps: SDI for paleoenvironment GIS data

Christian Willmes, Daniel Becker, Jan Verheul, Yasa Yener, Mirijam Zickel, Andreas Bolten, Olaf Bubenzer & Georg Bareth
Paleoenvironmental studies and according information (data) are abundantly pub-lished and available in the scientific record. However, GIS-based paleoenviron-mental information and datasets are comparably rare. Here, we present an OpenScience approach for collecting and creating GIS-based data and maps of paleoenvironments, and publishing them in a web based Spatial Data Infrastructure (SDI),for access by the archaeology and paleoenvironment communities. The Open Science approach to the publication of data, allows to properly cite the publisheddatasets as bibliographic...
