Cybercluster is a multi-master replication solution. Cybercluster has no single point of failure, an integrated load balancer, an integrated replication server, a monitoring server (to track replication), a consistency checker, an optional 2 Phase Commit for cluster-wide writing, support for all PostgreSQL features. Cybercluster is easy to setup. In contrast to many other solutions, Cybercluster is built on top of the PostgreSQL core and has full access to PostgreSQL internals. Cybercluster is heavily based on the concepts of PGCluster.
Bayesian Spam Filter is a class that can be used to detect spam in text messages using Bayesian techniques. It analyzes the text in terms of n-grams in a way that is idiom independent. It can be trained to progressively distinguish what is spam and what is not spam by detecting patterns in training samples. Training data is stored in a MySQL database.
