Stackless

Stackless Python is an enhanced version of the Python programming language. It allows programmers to reap the benefits of thread-based programming without the performance and complexity problems associated with conventional threads. The microthreads that Stackless adds to Python are a cheap and lightweight convenience which can if used properly, give the following benefits: Improved program structure. More readable code. Increased programmer productivity.

Kamaelia

In Kamaelia you build systems from simple components that talk to each other. This speeds development, massively aids maintenance and also means you build naturally concurrent software. It's intended to be accessible by any developer, including novices. It also makes it fun :)

LightCloud - Distributed and persistent key value database

* Built on Tokyo Tyrant. One of the fastest key-value databases [benchmark]. Tokyo Tyrant has been in development for many years and is used in production by Plurk.com, mixi.jp and scribd.com (to name a few)... * Great performance (comparable to memcached!) * Can store millions of keys on very few servers - tested in production * Scale out by just adding nodes * Nodes are replicated via master-master replication. Automatic failover and load balancing is supported from the start * Ability to script and extend using Lua. Included extensions are incr and a fixed list * Hot backups and restore: Take backups and restore servers without shutting them down * LightCloud manager can control nodes, take backups and give you a status on how your nodes are doing * Very small foot print (lightcloud client is around ~500 lines and manager about ~400) * Python only, but LightCloud should be easy to port to other languages
