Calvin Metcalf writes about PouchDB, which is neither TouchDB nor CouchDB:
Before we discus PouchDB we’re going to need to talk about CouchDB which Pouch is based on. […] So one of the issues with CouchDB is that Erlang…well lets just say people have mixed feelings about it, which lead to pretty quickly, CouchDB compatible Databases, Big Couch from Cloudant which you can cluster, TouchDB is a version written in Objective-C targeting embedded apps, and then we have PouchDB.
Hurry as you may run out of names: AouchDB, BouchDB, DouchDB, EouchDB, FouchDB, GouchDB, HouchDB, IouchDB, JouchDB, KouchDB, LouchDB, MouchDB, NouchDB, QouchDB, RouchDB, SouchDB, UouchDB, VouchDB, WouchDB, XouchDB, YouchDB, ZouchDB. For special requests we could expand to using unicode and emoji.

The Richshaw example page lists many other visualizations.
If you are asked to compare (or you just wonder about) the performance of link walking and map-reduce in Riak keep in mind the following details of how the two mechanism are implemented:

Jeff Darcy has written a while back about the (lack of) security in NoSQL database. Unfortunately things haven’t changed much and if you check the NoSQL + Node.js applications I’ve posted lately you’ll notice that some of them are completely ignoring security.
And there are some people realizing the risks and starting to express their concerns:
Playing with MongoDB lately, I’m getting scared. Because I’m seeing some really bad practices out there. Seeing it in live code. In tutorials.
Because of this, defenses against SSJS injection are also similar to SQL injection defenses:
- Validate user input used in SSJS commands with regular expressions.
Remember there’s no such thing as security through obscurity.
Salvatore antirez Sanfilippo has published on GitHub Lamer News a Hacker News like social site built on top of Redis, Sinatra, and jQuery—when writing this I’ve already checked out the code. For a long time Twitter-related and blog-related projects have been the favorite demos for NoSQL solutions, so its nice to see more serious applications featured.
The project is also running live at lamer news.com. It could benefit of a bit of UI liftup though.
