atomic operations

It's been almost a year since Ric Roberts posted about using MongoDB and MongoMapper and I've seen an explosion in the number of people using these tools in the Ruby community since then (I use them heavily on coder.io too).

A new version of the Rediska library has been released today, version 0.2.1.

Rediska is a PHP client for Redia, a key/value database system (written in C) that's similar to memcache.
