Installing Selenium on a Ubuntu VM with Vagrant

It uses VirtualBox to run the virtual machine then allows configuration of these machines with scripts. It stores your environments in “Box” files which are the base images

Introduction to XQuery

Whilst a JSON lad myself; the XML data type is commonly used, especially in applications using .Net and dealing with serialization. Data sets provided in XML can be parsed with relative ease using C#; however in SQL Server it can be tricky especially when you want to work in sets.

Microsoft Azure

Thoughts on using Azure Service Bus Queues

Recently we switched from using the Azure Queues as part of the standard storage account to using Windows Azure Service Bus. The primary motivation behind this was: * In-built dead letter queues * Ease of complete and abandon operations * The opportunity to use topics and subscriptions in the future The initial transition
