Subject Re: CouchDB presentation in Portland tonight
Date Sun, 06 Sep 2009 22:09:19 GMT
In case anybody is interested I put some notes from my CouchDB talk
online <http://groups.google.com/group/pdxruby/t/1ddf27e0e51b7f75>.
These include some brief notes on three high-level interfaces to
CouchDB for Ruby: CouchPotato, CouchRest::ExtendedDocument, and
CouchFoo.
