Twitter is built on open source software, from the back-end to the front-end. Twitter engineers use, contribute to and release a lot of open source software. We of the Twitter Open Source Office support a variety of open source organizations and are grateful to the open source community for their contributions, and want to maintain our healthy, reciprocal relationship.

  • Mesos - Security and Authentication Support The project consists mainly of implementing authorization and authentication support to Apache Mesos, making use of MIT Kerberos, so that only allowed frameworks will be able to register and submit jobs.
  • Netty Asynch DNS I would like to add asynchronous DNS capability (so as to avoid blocking calls using the java built-in API).
  • Scalding: Matrix optimizations The aim was to optimize the Matrix API layer of Twitter's Scalding library in Scala. The main optimizations were done in two areas: 1) matrix chain multiplication, 2) various operations on sparse and skewed matrices.
