Out-HtmlView – HTML alternative to Out-GridView

A few weeks ago, Mateusz Czerniawski, mentioned that he wants to build a Status Page for his company services. While I haven’t needed for myself, it seems like an excellent idea to try and create one in PowerShell. Since I’ve been working on PSWriteHTML for a while, it wasn’t that far fetched idea. While PSWriteHTML has a long way to go, to be in a state I want it to be, after a few days I had a prototype that didn’t require much work to generate. If you’re wondering what Status Page is it’s a little summary page for your users to check what is the status of services they use. It has been popular in the last few years and is offered by many services (Twitter, GitHub, Office 365 – they all have it). Companies are selling it as a service as well where you can host your status page for your users. This one is free.

I’ve been using Ubiquiti Unifi for some years now, for both home and work usage. It’s great hardware at a great price, and the best thing for a software maniac like me is that it’s continuously updated. Some time ago I upgraded Ubuntu to 18.04, and things went a bit sideways. You see Unifi started to add to their DEB packages that Mongo 3.6 is not supported and therefore blocking any installation. The idea is, it works perfectly fine on MongoDB 3.6 but migration between 3.4 to 3.6 is just not straightforward. Long story short when I upgraded Ubuntu I was suddenly greeted with not working Unifi.  I’ve fixed that, and blogged about it how you can do so using manual steps – Ubuntu 18.04 – Fixing Unifi .deb package to run with 3.6 MongoDB. The thing is with each new version out I have to do multiple steps to fix every single package from Unifi (you see where I’m going right?). While a few years ago I would be stuck to use bash or some other workaround which would be a pain for me, this is 2019, and PowerShell Core works excellent on Linux systems! I know that installing PowerShell Core for hardcore Linux fans may not be as fun as it is for me, but you do get a lot of benefits from it.

Microsoft Teams over the last few years have grown into an excellent and flexible tool for both small and big companies. Having the ability to chat with users, store files or have all sorts of data in one place makes it easy and functional. Of course, it has its fair share of issues, but it’s getting better. One of the cool features of Microsoft Teams is being able to send notifications to Microsoft Teams Channels using WebHook Notifications. In the beginning, this feature was pretty limited, but after a few years, it got much better with support for Adaptive Cards, List Cards, Hero Cards, Thumbnail Cards, and Office 365 Connector Card.

As you may know, PowerShell has multiple streams. Write-Output, Write-Error, Write-Warning, Write-Verbose, Write-Debug, and Write-Information. It also has Write-Host which until PowerShell 5 was a bit special. Since PowerShell 5.1 it’s a wrapper over Write-Information, so it doesn’t kill puppies anymore. While I could spend the next five pages trying to give my best and describe those streams, there are already many articles describing them in detail. Please check the following link if you need that information.

Working as a freelancer is a great thing if you can handle it. Each day, each week something new happens and a new problem shows up on my doorstep. It also means it’s almost never boring at your job and you get to play with new stuff. But there’s one drawback to this. You’re often thrown at the problem, told to fix it but often that’s about as much information as you get. It wasn’t very different today. I was told to switch Office 365 from ADFS to Password Synchronization. While reasons for this are not really important, the important question here is what is the name of AD Connect server that’s responsible for this configuration?

When you work with HTML, CSS, and JavaScript, you often meet three versions on how those are stored in files – minified, formatted, somewhere in the middle (usually a total mess). I have all three versions in my PSWriteHTML module. Some are minified 3rd party resources, some are generated by my PowerShell commands (and are a total mess when it comes to formatting), and finally, some are formatted resources by using built-in VSCode features. In whatever form they are, they generally have no impact on how browsers display them. Browsers will read them in any kind and not care for how they look.

Everyone now and then, there comes a moment you need to add a user into Administrators group on each computer…

A few days ago, I tried to use Install-Module on the old Windows 2008R2 system that I use for specific tasks.

I shouldn’t be telling you that, but Active Directory Backup is an essential part of your Active Directory setup. When a backup of Active Directory happens, AD is aware of it. Following PowerShell solution allows you to get Active Directory Last Backup Time for the whole forest or by domain.

PasswordSolution uses the DSInternals PowerShell module to gather Active Directory hashes and then combines that data into a prettified report. If you have ever used DSInternals, you know that while very powerful, it comes with raw data that is hard to process and requires some skills to get it into a state that can be shown to management or security.

A few weeks ago, I posted a concept migration diagram for Office 365 to Twitter and Facebook. Today I thought I would show you how you can do it yourself using PowerShell and PSWriteHTML PowerShell module. When I started working on this, I’ve thought I want to create before and after infrastructure to see how it will look when migration ends. I’ve initially planned to assign myself an Office 365 Visio Plan 2 license and do something manually, thinking it may be just much easier. Unfortunately for me, there were no free Visio licenses in my tenant, and my laziness took over, so I’ve decided to give it a go using PowerShell only.

I’ve been working with PowerShell Modules for a while now, and most of my knowledge about them came from Warren F (psCookieMonster) blog about Building a PowerShell Module. It is a handy piece of information and recommended read for anyone starting up writing PowerShell Modules. He introduces an idea where a module is stored in multiple folders Private, Public, Bin, Lib and so on and having YourModule.psm1 as a wrapper for functions, binaries in those folders, where each function is stored in its file. It’s an excellent concept, and I use it every day. It allows me to jump into a file quickly I want to find and fundamentally easier for development, especially in teams.

I had this little issue today when I tried to schedule the Microsoft Graph script to run as a service account on a certificate. To my surprise, even tho I had all permissions required, I was getting this error message: Connect-MgGraph: Keyset does not exist. Something that didn’t show up for my user.
