In Koparo, a newly-formed company developing measurement systems for golf pros, we build embedded data acquisition systems using ATMEL based devices like the Arduino. We program the embedded devices in Ada (using the subset available in the GCC-based AVR-Ada compiler).

The children's game universe ""Crimeville" is the first product from the game development company Art of Crime. It challenges the players to solve detective riddles cooperatively. One component -- a language server -- created for the on-line version of the game is Open Source.
The language server uses pre-existing Open Source spell-checking components glued together with application logic written in Ada.

An introduction into the Zarafa Collaboration Platform as an Microsoft Exchange alternative. The talk focuses on the Open Source parts and its features regarding integration into existing or up-coming environments. Of course the architecture and structure as well as interesting features and some future plans are mentioned as well. If enough participants are interested, a tiny discussion about wanted or interesting features would be very interesting, too.

A technical introduction talk about SELinux, the Security Enhanced Linux extension in the Linux kernel. Typical target audience are intermediate Linux users, as it covers the SELinux history, the structure and how it works. Of course, daily issues and how to solve will be explained, too. As SELinux gets more and more used, some management and handling hints and tricks will help SELinux beginners to use it rather to turn it off.

OpenStreetMap is an international crowdsourced project. The purpose is to create an open and free map of the world - something along ""a Wikipedia for maps"". Thousands of volunteers have created maps which in Denmark among other places is comparable with commercial ones and on a regular basis have ""first""s with day to day mapping where roads are added the same day they are accessible.

"Everyone knows OpenWRT - the linux-based wifi router firmware. ZRouter.org is just the same, but based on FreeBSD and aiming at a 100% BSD-licensed solution. The project is slowly progressing and device support is extended. This presentation is about where we are today, and where we expect to be tomorrow.
This includes :
- supported devices
- what's missing
- features
- FreeBSD-relation
- Getting started"

Speaker: Niels Kjøller Hansen and Rasmus Espholm borger.dk was in the need of an application for embedding maps in a webpage. VisKort (literally ShowMap) was developed for the purpose and released as open source. Now 3 years later the application is in widespread use in the public sector and a community is starting to form around it. Or is there?

So much more than a serial port with power
Note: Right after this talk Peter Stuge will host a workshop: Make a USB device with an ARM Cortex-M3 board. Please consider joining it.
Learn about the benefits and limitations of the Universal Serial Bus, how communication works on the bus, how and why the right (and sometimes wrong?)
driver can be loaded automatically by the operating system, and find out the easiest way to add USB to your washing machine, toaster, or other favorite
appliance.

There have been a focus on open source software in the Danish public sector since 2006 in the Ministry of Science Technology and Innovation. With the new government in October 2011, the responsibility for open source moved to the Ministry of Finance. How does that affect the open source focus? Will there still be a forge and initiatives like Kod i ferien (Holiday coding)? This talk gives a preliminary prediction about the future in this aspect.

The First Thing Tak Did - Elegant Remote Control For Sysadmins
Tak is a program for running everything from system commands and shell scripts up to complex multi step workflow-based requests on multiple systems simultaneously.
The First Thing Tak Did, He Wrote Himself.
Able to bootstrap cleanly on any LSB compliant system (and, frankly, every common server OS I've yet tried it on), Tak is able to push its core components over an ssh connection so while little installation is required on the master machine, none at all is necessary on those being controlled.

PostgreSQL 9.1 arrived with a new featured called KNN-GiST, or fast K-Nearest-Neighbour searching. Many people don't realize what that means, and what they're good for. This walk will look into both the more obvious geometrical and geographical cases, as well as the more surprising use-cases such as string matching and similarity (indexed LIKE lookups, anyone?).
|
PostgreSQL 9.1 was recently released, but the development of 9.2 has already reached a point close to feature freeze. This talk will take a look at some of the things that are already available in what will eventually become PostgreSQL 9.2.

When Oracle bought Sun, the OpenSolaris project got closed. Many people expected that would be the end, but they couldn't have been more wrong. This talk will introduce the Illumos project and explore some of the progress that's been made. Some time will also be spent looking at the distributions based on Illumos.
|
Now more than six years after the release of Apache 2.2 we now have version 2.4. The talk will cover new modules and features in 2.4 and attempt to guess where the next version will be going.

Speaker: Mads Ruben Burgdorff Kristensen Copenhagen Vector Byte Code, cphVB, is a high performance runtime backend for Numerical Python (NumPy). cphVB automatically transforms regular sequential Python/NumPy applications into high performance applications with the capacity of utilizing a broad range of platforms, e.g. Multi-core CPUs, GP-GPUs, Clusters.
cphVB enables non-computer experts to develop applications in the high-productivity language Python while enjoying the high-performance capability of the executing platform.

This talk shows some approaches of object serialization from qualitative and quantitative aspects. Those are object serialization in Java, IDL, XStream, Protocol Buffers, Apache Avro, and Thrift, GSon, Jackson, JsonLib, JsonMarshaller, and JsonSmart. One more approach, called RugsOn, is also shown. It is a structured data representation based on Ruby designed by the speaker.

Stackato is a cloud solution from renowned ActiveState. It is based on the Open Source CloudFoundry and offers a serious cloud solution for Perl programmers, but also supports Python, Ruby, Node.js, PHP, Clojure and Java.
Stackato is very strong in the private PaaS area, but do also support as public PaaS and deployment onto Amazon's EC2.
The presentation will cover basic use of Stackato and the reason for using a PaaS, public as private. Stackato can also be used as a micro-cloud for developers supporting vSphere, VMware Fusion, Parallels and VirtualBox.

Scripted environments are brought forward as the future of embedded user interfaces. Be it HTML5, QtQuick or any other technology - it still requires a run-time environment. This speech discusses the construction of such a run-time from a Qt (and QtQuick) viewpoint, but also refers to what is possible through the QtWebKit module today.

Ladon is a framework for Python that simplifies web service development. Ladonized class methods are exposed to several internet service protocols at once. Service descriptions (like WSDL) and browsable API documentation is generated automatically from the service source. Besides SOAP, Ladon implements a new protocol called JSON-WSP which has a smaller network footprint and is ideal for rich web application development. In this talk I will try to explain the motive for developing Ladon, cover the main features and show some live examples.
