If there's anything I've learned about powershell it's how messy the documentation is. How is that Lean Architecture book? My degree is actually in computer science but I've always done either sysadmin jobs or electronics repair. So I've always been interested in different methods of agile software development. I'm pretty sure SCRUM is still pretty popular but I honestly have no idea how it works...
Yea we are going through a large transition to Agile in my company right now, its exciting and painful all at the same time. Lots of talk, whether it works is another story. I like Agiles core concepts but the snake oil salesmen have set up camp and it gets promoted as a solution to all problems. It cannot fix bad code/people/processes for you... The Lean Architecture book is a recent purchase, not sure about it yet really. I bought it without seeing the rather mixed reviews which has soured me on it a little.
