I dedicate a small part of my life to open source software. Following is a list of projects I have worked on:
exp4j is a small java library for parsing mathematical expressions. I have created and maintained this project for 8 years, but I’m looking for someone to take over from me, since I do not have the time this projects deserves.
crumbs is a bookmarking system for a bash like terminal emulation written in C. It allows you to store command invocations in a hierarchical namespace.
The Fedora Commons Repository is a distributed repository software, that allows you to store data and enrich it with metadata in a semantic graph.
Scape stands for SCAlable Preservation Environment. This project was funded by a European Union Research programme in order to create a distributed platform for storing arbitrary data, ernich it with standardized metadata and provide various tasks around data preservation.
Lately I’ve gotten into Linux Kernel development in order to grow as a C Developer. I am convinced there’s a lot to learn from such a large and knowledgable community and I am determined to take on the challenge.
