Creating MongoDB Shards and Replica Sets with PowerShell

In the MongoDB University course "M101N: MongoDB for .NET Developers", there is a walk through of a UNIX script to create a 3x3 set of shards and replica sets. To brush up on my MongoDB and my Powershell, I decided this weekend to try to rewrite and extend the script in Powershell. A somewhat painful, but ultimately rewarding, experience: You can see what I came up with here.  In this post I will walk through some of the powershell and some of the MongoDB syntax and tricks.

Custom Sitecore Log files

Starting with Sitecore 6.2, and especially since Sitecore 7 we've seen an increase in specific log files: WebDAV, Crawling, Search, Publishing, FXM. This is completely configurable, and can be leveraged to keep your application logic separate from the Sitecore log file while still using Sitecore's logging capabilities.

Autofac Aggregate Service

There is a nice little feature of Autofac called Aggregate Service, that works very well with NSubstitute's recursive mock functionality to make tests much more maintainable and resilient to dependency modifications.

A RoboMongo Trick

RoboMongo is a nice tool for digging around xDB databases. It provides the full feature set of the JavaScript shell (you can save variables, run help commands, etc.) and allows you to do things like edit documents directly through the JSON display.
