In past years the 3 furies have shared their insights on various things people do wrong in PowerShell. Let's take that one step further and demo all those things and what you should do instead. We'll explain why it's bad and the other way is better, because code without context doesn't help anyone.
A lot of talks about "Best Practice" are aimed at showing you what you should be doing but not many take the approach of showing what you shouldn't be doing and how to change it. This can make it more difficult to grasp as it might not easily relate to how someone is currently working or has been working, showing the wrong way to do things is more approachable as everyone was a beginner at some point and many people made the same mistakes. Taking this one step further and providing reasoning why one approach is the wrong or worse way to handle something can also allow people to make an informed decision on using that approach anyway, if their circumstances require it.

PowerShell Summit videos are recorded on a "best effort" basis. We use a room mic to capture as much room audio as possible, with an emphasis on capturing the speaker. Our recordings are made in a way that minimizes overhead for our speakers and interruptions to our live audience. These recordings are meant to preserve the presentations' information for posterity, and are not intended to be a substitute for attending the Summit in person. These recordings are not intended as professional video training products. We hope you find these videos useful the equipment used to record these was purchased using generous donations from members of the PowerShell community.
