The PowerShell Conference Book

“Imagine attending a PowerShell conference where over thirty speakers who are subject matter experts in the industry are each presenting one forty-five minute session. All of the sessions are at different times so there's no need to worry about choosing between them. You might be wondering how much a conference like this will cost by the time you pay for the conference, hotel, airfare, and meals? Well, there's no need to worry because this conference doesn't cost a fortune because it's actually a book that's designed to be like a conference.”


- From “The PowerShell Conference book”


There is a new book in town and it is not a regular book. It is designed to be like a PowerShell conference where the topics are divided into sections ranging from “PowerShell Scripting” to “CloudOps/DevOps”. Each chapter in the book is written by industry experts, hence every chapter is unique and independent. I am very humble and proud of being able to announce that I have written a chapter in this book called “Increasing PowerShell Performance”.

The book is not yet complete, however it is available on Leanpub and if you buy it now, you can download new content as it becomes available at no extra charge. All the royalties from the book are donated to the OnRamp scholarship program. You can checkout the progress of the book or by it at this link https://leanpub.com/powershell-conference-book.

I want to thank Mike F Robbins for the opportunity and the other two editor Jeffery Hicks and Michael T Lombardi. Writing the chapter has been a smooth process and a pure pleasure. In addition it feels good to able to give something back to the community.

Serialize data with PowerShell

Currently I am working on a big new module. In this module, I need to persist data to disk and reprocess them at some point even if the module/PowerShell session was closed. I needed to serialize objects and save them to disk. It needed to be very efficient to be able to support a high volume of objects. Hence I decided to turn this serializer into a module called HashData.



Other Serializing methods

In PowerShell we have several possibilities to serialize objects. There are two cmdlets you can use which are built in:
Export-CliXmlConvertTo-JSON
Both are excellent options if you do not care about the size of the file. In my case I needed something lean and mean in terms of the size on disk for the serialized object. Lets do some tests to compare the different types:


(Hashdata.Object.ps1)

You might be curious why I do not use the Export-CliXML cmdlet and just use the [System.Management.Automation.PSSerializer]::Serialize static method. The static method will generate the same xml, however we …

Creating Menus in Powershell

I have created another Powershell module. This time it is about Console Menus you can use to ease the usage for members of your oranization. It is available on GitHub and published to the PowershellGallery. It is called cliMenu.






Puppies
This is a Controller module. It uses Write-Host to create a Menu in the console. Some of you may recall that using Write-Host is bad practice. Controller scripts and modules are the exception to this rule. In addition with WMF5 Write-Host writes to the Information stream in Powershell, so it really does not matter anymore.



Design goal
I have seen to many crappy menus that is a mixture of controller script and business logic. It is in essence a wild west out there, hence my ultimate goal is to create something that makes it as easy as possible to create a menu and change the way it looks.
Make it easy to build Menus and change them Make it as "declarative" as possible
Menus
The module supports multiple Menus, however only one Main-Menu with as man…
