Adds pessimistic locking capabilities to the redis gem. Since these capabilities are utilized client-side, all clients must use this gem and follow the order of lock => make changes => unlock in order to obtain maximum safety when modifying sensitive keys. Tested with redis-server 2.0.4 and should work with all versions > 0.091.

Linnaeus provides a redis-backed Bayesian classifier. Words are stemmed, stopwords are stopped, and redis is used to allow for persistent and concurrent training and classification.

LLM Memory is a Ruby gem designed to provide large language models (LLMs) like ChatGPT with memory using in-context learning. This enables better integration with systems such as Rails and web services while providing a more user-friendly and abstract interface based on brain terms.

Yet another Ruby distributed lock using Redis, with emphasis in transparency. Requires Redis >= 2.6.12, because it uses the new syntax for SET to easily implement the robust algorithm described in the SET command documentation (http://redis.io/commands/set).

This library implements application mutexes using Redis. The mutexes are shared between separate threads, processes, or machines. Locks are acquired with an expiration time so if process that holds a lock dies unexpectedly, the lock is released automatically after a certain duration.
