Time [in minutes]: 1 Platform [OS, libraries, etc.]: Google Chrome Skill level: I can build complex software like GCC and the Linux kernel (Skill required: none?) From the Arizona Technical Report (accessed 3/20/2014): "A small number of systemshad [sic] online implementations and thus did not need to be compiled. We marked these as 'builds.'" The online Javascript-based demo linked from our paper that the Arizona study authors accessed is accessible at http://pbs.cs.berkeley.edu/#demo and successfully runs. However, a full implementation in Cassandra shipped in Cassandra 1.2.0 and is also available at: https://github.com/pbailis/cassandra-pbs (We were not contacted regarding the study.) The above code builds and requires Apache Ant: git clone https://github.com/pbailis/cassandra-pbs.git cd cassandra-pbs; ant Additional source code and build/run information can be found at: http://www.bailis.org/blog/using-pbs-in-cassandra-1.2.0/ https://github.com/shivaram/pbs-paper-cassandra-historical
