Adaptive monitoring in microkernel OSs [PDF]

open access: yes2010 International Conference on Dependable Systems and Networks Workshops (DSN-W), 2010
The microkernel architecture has been investigated by both industries and the academia for the development of dependable Operating Systems (OSs). This work copes with a relevant issue for this architecture, namely unresponsive components because of deadlocks and infinite loops.

OSS Myths and Facts

open access: yesCoRR
We have selected six myths about the OSS community and have tested whether they are true or not. The purpose of this report is to identify the lessons that can be learned from the development style of the OSS community and the issues that need to be addressed in order to achieve better Employee Experience (EX) in software development within companies ...
