The development processes of open source soft-ware are different from traditional closed source development processes. Still, open source software is frequently of high quality. This raises the question of how and why open source software creates high quality and whether it can maintain this quality for ever larger project sizes. In this paper, we look at(More)

In any defense mechanism, malicious code detection is a crucial component. To subvert malicious code detectors, e.g anti-virus software, malicious code writers try to subvert these detectors by obfuscating the malicious code. As testing results surprisingly showed, commercial virus scanners were not able to detect infected binaries which were transformed by(More)
xAnVi is an extensible framework for the analysis and visualization of graphs. The framework consists of a small core to manage resources, plugins and extension points and an arbitrarily expandable set of plugins to provide the actual application functionality. This paper describes the design approach to create a modular bioinformatics toolkit/framework(More)
