I've been mentoring two students in the Google Summer of Code program this year.
Nirmal's GSoC project was to develop a tool to generate SCA composite diagrams using SVG.
Eranda's project was to develop SCA datastore components using Apache Cassandra, CouchDB and Hadoop.
Both students just passed the final GSoC evaluations! They should be proud of what they've achieved this summer!
I hope we helped them learn a few things, and that they'll continue to be involved with open source in the future.
