DevOps: A Career Changer

Once upon a time, there was this woman at a TechMentor conference a few years ago, sitting in the front of the room during the “Don and Jason" show, a not-quite-scripted discussion on various “lightning” topics.

Pester – Parameters and Hashtable Fun!

I have written a short excerpt on how to pass parameters from an object to a Pester test. I have turned this into a function: Invoke-POVTest. The function is primarily for operational validation tests, where you might have a single operational test but you need to test multiple cases. (Sorry, I am not quite sure if I described it properly). I’ll be interested in any feedback. Link to blog post here.

The Key to Understanding PowerShell – on Windows or Linux

I’ve listened to a few of my Windows-friendly compatriots attempting to explain PowerShell to their Linux colleagues, and it hasn’t always gone well. The problem, I think, is that a lot of Windows folks don’t actually know why PowerShell exists in the first place. Let me explain.

I took a different approach in my three-part series, A Plethora of PowerShell Pitfalls. The first two parts are presented in quiz format, together covering the top 10 “gotchas”. They will help you test your awareness to see if you even realized the danger and did not know you’ve been skirting those traps for awhile.

The Flavors of Windows Containers

I had a wonderful conversation with some team members around Windows Containers generally, and they had some very cool analogies that I don’t think have been publicized enough. There’s some good technical detail, too, which I think is worth understanding as we move into this brave new world of containerization.

Pitfalls of the Pipeline

Pipelining is an important concept in PowerShell. Though the idea did not originate with PowerShell (you can find it used decades earlier in Unix, for example), PowerShell does provide the unique advantage of being able to pipeline not just text, but first-class .NET objects. Pipelining has several advantages: It helps to conserve memory resources. Say you want to modify text in a huge file. Without a pipeline you might read the huge file into memory, modify the appropriate lines, and write the file back out to disk.
