Open Source Software

You can find my personal open source software projects primarily under my GitHub account. But because nowadays I work full-time on Apache Kafka there’s not much time left for personal projects.

Example projects:

Wirbelsturm – Vagrant and Puppet based tool to perform 1-click local and remote deployments, with a focus on big data related infrastructure such as Apache Kafka and Apache Storm
akka-mock-scheduler – To test scheduler-dependent code in Akka for Scala
avro-cli-examples and avro-hadoop-starter – How to use the Avro data format
golang-docker-build-tutorial and java-docker-build-tutorial – Project templates to dockerize golang and java applications

SPEAR Ranking Algorithm

Ching-man Au Yeung and I have developed the SPEAR ranking algorithm for ranking users in social networks by their expertise and influence within the community.

SPEAR Algorithm: Discoverers and Followers

Our work on SPEAR has been covered by international press and news media, including Technology Review and Communications of the ACM as well as the world’s top technology blogs such as ReadWriteWeb. We have been also very happy that Yahoo! invited us to write a featured article about SPEAR, considering that we used its social bookmarking service Delicious.com (which was owned by Yahoo back then) as data source for our scientific experiments.

For starters, you want to read my quick introduction on how to use the SPEAR Python library.
