Got this error trying to update a field in a mongodb collection. Turns out I was previously using the same field to store object Ids. Now that I’m trying to repurpose the field to store a different datatype, mongo throws an error. Solution was to remove the old field completely from all documents within the [...]
Things change quickly in the world of node development, you’re usually working with a lot of different modules within your projects. Fortunately there’s a great package manager that most node developers used called NPM. It makes installing and updating dependencies in your environment fairly simple. At anytime you can see a list of installed packages [...]
The docs on MongooseJS can be really unclear at times, here are some pointers on validation that may help (note this is valid as of MongooseJS 1.3.3)

});
Note: If your collection exists in Mongo, you need to drop the collection before schema changes kick [...]

W3wp.exe is the worker process that Internet [...]
In my last post, I mentioned the Internet Information Services (IIS) Manager feature called Worker Processes, and explained how you can use it to glean information into high cpu utilization for the w3wp.exe process(es) running on your server. If you followed the steps and got the following error: “There was an error while performing this [...]
We had several users reporting an error when deleting a SharePoint team site. The error appears as a “File Not Found.” on the WebDeleted.aspx layout page along with a stack trace. It appears that the problem stems from our custom master page. For our implementation we use a custom HttpModule that redirects incoming requests for [...]
For the past two SharePoint implementations that I’ve worked with, it was a common business requirement to query from a list to retrieve items that should be displayed on a “scheduled” basis. Think along the lines of an alert or announcement. Typically what I end doing is create a custom list and add the following [...]
So you have an instance of a SPListItem and want to know whether this item belongs to a Document Library or if it came from a list (such as an Event Calender, Survey, or Custom List). A quick way to distinguish a document library item is to access the ParentList property of the SPListItem class and examine [...]
