How to handle oAuth from PowerShell
One of the coolest features of PowerShell is the many tools we have available to work with services on the web, be they SOAP, REST, RPC or even WSDL services. It’s no question, PowerShell makes it very easy to pull down data from any of these places.
Unfortunately, getting data from a service isn’t always as easy as embedding your credentials in a URL. In fact, some services require us to authenticate and ask the user for permission before giving up the goods. For these, oAuth is the de-facto standard for delegated access.
In this blog post today on FoxDeploy.com, we cover an easy method to present a user with an oAuth window to ask for permission, and offer a guide of how to handle the somewhat complicated flow of credentials and URLs needed to delegate permissions, using WordPress as an example.
Special Thanks
This post couldn’t have happened without contributions by Lee Holmes, Adam Bertram, Keith Hill, Chris Wu, and Ryan Yates for helping me to understand how to safely store credentials, and for other questions. Extra thanks go to Adam and Ryan for helping me fact-check the post, and to Chris Wu for his excellent write-up on the ‘Hey, Scripting Guy’ blog.

Media Sync: Organize Your Photos and Videos with PowerShell
Do you have photos and videos that you have taken over the years that are scattered all over the place? Do you want to have all your photos and videos organized? Do you want all your photos and videos to have a standardized naming scheme? If you answered YES to these questions, then this is the post for you. In this post, I will provide you with the PowerShell code and examples for how to use the Media Sync script. The Media Sync script utilizes the Shell.Application COM object to gather file metadata. Only files that have a picture or video metadata type will be processed. The script uses the date taken for pictures and the media created metadata fields to organize the photos and videos. If there is no date taken or media created available for a given file, the script will use the modify date instead. The script also ensures that you won’t have any duplicate files by checking the file hashes of the two files in question. If the script detects duplicate files, it will only keep one copy of the file. There are also tools included to help you cleanup unwanted files or folders, delete empty directories and find duplicate files. The script has a simple menu driven PowerShell GUI similar to what I did in a previous post . The Media Sync PowerShell script provides the following features:
