In PowerShell it is possible to use custom properties for an object if the one you need does not exist by default - these are known as calculated properties.
For instance, in PowerCLI by default there is no ToolsVersion property for a VM, however we can create a calculated property named ToolsVersion and submit an expression to retrieve that data:
Get-VM TEST01 | Select-Object Name,@{Name="ToolsVersion";Expression={$\_.ExtensionData.Config.Tools.ToolsVersion}} However, the ToolsVersion property does not persist after running this command, so if I now try:

The question we have been asked the second most was back in April, “Why is the Kindle version more expensive than the paperback?”. At the time we went back and forth with both the publisher and Amazon and received conflicting answers. Well now that is back in the various Kindle stores again, this situation also seems to have improved and typically it is slightly less than the paperback in price.
When working with PowerCLI in a large environment and retrieving large amounts of data, particularly when using the Get-View cmdlet, you may receive the following error: Get-View Exception of type ‘System.OutOfMemoryException’ was thrown
Looking at the available memory on your system may cause you to wonder why you receive this error message. It may occur because you are running the 32-bit version of PowerCLI where the size of the heap is limited to 1.
Having been using the beta for a while, I was very pleased to see that PowerGUI V3 has been released. Some of the new features / fixes that I like the best are:

Most projects have to start somewhere as an idea, and this one was no different. When Sybex contacted us, our idea suddenly became a reality and now after quite a journey, our book has finally arrived. Because most of the content of this book is inspired by the PowerCLI community, we decided to give something back. To celebrate the release of our book, we’re organizing a book raffle. Read the instructions below and enter the draw for a chance to win a free copy of “VMware vSphere PowerCLI Reference: Automating vSphere Administration”.
Whilst attending the recent MVP summit I was fortunate enough to get some podcast recording time with Travis Jones from the PowerShell product team. We are able to have a chat about the upcoming PowerShell Deep Dive Conference and the kind of treats instore for those lucky enough to attend. There’s still time to register for the conference so I highly recommend you do if you have the chance to attend.
