OpenSource Involvement (= Software Development)

March 2006 - ongoing:
Research related software development introduces GeoCast, a simple standard specification for extrinsic and intrinsic parameters in frame based video.
April 2003 - April 2004:
Software investigation for a videowall project, especially regarding video YUV to RGB colorspace conversion, lead to gstsert, a video-as-pointcloud demo application using state-of-the-art Linux hardware acceleration for video and 3D graphics.
August 2002 - February 2003:
Developed a multi-threaded, shared-memory MPEG2 video decoder for 3D applications, called TexMPEG, as part of the diploma thesis. Demonstrated at two Virtual Reality facilities in Groningen, Netherlands and Norrköping, Sweden.
August 2002 - February 2003:
Developed a depth-storage extension to MPEG2 with the according prototype software, called MPEG Z/Alpha. Lies in-phase with current research on 3D video storage.
January 2000 - November 2002:
Held several small lectures at the university campus on the mentioned software projects.
2000 - 2002:
Convinced company hardware engineer to provide above software projects with driver source code.
May 2000:
Created the MJPEG/Tools project together with Andrew Stevens, acting subsequently as project leader for public relations, technical documentation writer, and developer. The MJPEG/Tools are one of the most sophisticated Motion JPEG and MPEG2 encoding tools available on the Linux platform. The Iomega Buz/Miro DC10 driver is by now part of the Linux kernel, thanks to Ronald Bultje, one of the project's developers.
Aug' 1999:
Created the Matrox Marvel/Linux project based on earlier work by Eduardo Galvez. Same role as in the MJPEG/Tools project. Provides a stable driver and gave hundreds of users use for their video hardware in Linux.
August 1998:
Created the Buz/Linux homepage and according video applications together with Rainer Johanni, Germany. The Iomega Buz was the first Motion JPEG hardware supported in Linux.

August 1998 - running project:
Created various documentation for the mentioned software projects, under constant review of the project software users.
August 1998 - running project:
Active participant of several user and developer support mailing lists, with a total of 300-400 outgoing mails per month.

Miscellaneous facts

Planned and conducted six years of studies in another European country, shortly after Sweden and Austria had joined the European Union in 1995, being one of the first "EU free movers" for MSc studies in these countries.
First student to study the Visualization profile at the subsidiary campus in Norrköping, Sweden, in combination with the MSc computer science and engineering education offered at the main campus in Linköping.
A contact on the SGI OpenPerformer mailing list led to a diploma thesis employment at the HPC Groningen, Netherlands, lasting for six months (Supervisor: Frans van Hoesel).
Founded a small Swedish one-man company, Geofront, to learn about bookkeeping, tax issues and work as a professional freelancer. Work as freelancing translator/consultant required the establishment and nourishment of miscellaneous business contacts.
