If you want to experiment on a single Windows box, use the steps below: Start by creating the data directories: c:\Users\John> cd c:\data c:\data>mkdir masterdb c:\data>mkdir slavedb1 c:\data>mkdir slavedb2 Startup the master database (I assume you've of course added Mongo's bin directory to your ... http://www.dllhell.net/index.php/2010/07/27/on-mongodb-master-slave-configuration/ One of the first things I noticed when I started to move some code from NHibernate/SQL Server to NoRM/MongoDB is that ObjectIds look funny in MVC URLs. In other words: http://codevoyeur.com/articles/show/bd342503dbbd3c94e1010000 vs. http://codevoyeur.com/articles/show/10 NoRM's overloaded operators let ObjectIds and strings play nicely together so there's no real problem with MVC routing. ... http://www.dllhell.net/index.php/2010/07/23/on-sequences-with-mongodb-and-norm/ MapReduce can be a confusing concept to understand at first. It's not that it's some terribly complex thing, but rather when you work with it in tools like MongoDB, you're simply not exposed to all the pieces. I'm hoping this post helps to put the puzzle together... In MongoDB, ... http://www.dllhell.net/index.php/2010/07/17/on-mapreduce-in-mongodb/ Another Code Voyeur article showing how to replace XML or compiled configuration with IronPython.

As I was listening, a line caught my attention - "Lord, I wish I could be peaceful. But there can be NoSQL." Later on they continue with ... http://www.dllhell.net/index.php/2010/07/06/on-relational-against-the-machine/ Whenever I write about shared hosting, it's not a good thing. It usually means another host has gone from good or ok to just plain awful. Not too long ago, I wrote in Part V that WebHost4Life appeared to be a keeper. They had a great, bare ... http://www.dllhell.net/index.php/2010/06/23/on-shared-hosting-part-vi/ As part of a presentation I'll be giving at the Hartford Code Camp this Saturday, I've started to work through the task of converting NerdDinner to run on MongoDB using the NoRM driver. This is the first in a short series of posts on the process. To get started, ... http://www.dllhell.net/index.php/2010/06/14/on-running-nerddinner-on-mongodb-with-norm-part-i/ A Code Voyeur article demonstrating how to create an extensible repository base class using NoRM and MongoDB. http://www.codevoyeur.com/Articles/20/A-NoRM-MongoDB-Repository-Base-Class.aspx http://www.dllhell.net/index.php/2010/05/28/on-a-norm-mongodb-repository-base-class/ While most .NET developers who want to work with MongoDB focus on C# with NoRM and MongoDB-CSharp, there's an alternative - IronPython and PyMongo. PyMongo is the 10Gen developed Python driver for MongoDB. It's actually pretty easy to get it working with IronPython. The steps are as follows: Download PyMongo ... http://www.dllhell.net/index.php/2010/05/27/on-using-pymongo-with-ironpython/ I speak just enough Italian that I'm able to order a glass of Chianti and find my dog a toy in a Venetian marketplace. Nonetheless, I've been published in the Italian DEV magazine (which I think is pretty cool).
