  • Microsoft Graph PowerShell SDK V2.28 Attempts to Restore Stability
    On May 10, 2025, Microsoft released V2.28 of the Microsoft Graph PowerShell SDK in the hope that the new version would fix a bunch of annoying problems that have dogged the SDK for several months.

  • What are GitHub Copilot instruction files? A simple usage example
    In Visual Studio Code version 1.100, Microsoft introduced GitHub Copilot instruction files, which mirror the Rules feature in AI IDEs like Cursor and Windsurf.

  • Get SharePoint List Column Details [Internal Name, Display Name, Data Type] Using PnP PowerShell
    A few weeks before, I developed a Power Apps application for a client that takes data sources as a SharePoint list. There are almost six lists, and each list has more than 20 fields. Due to some permission issues, we had to manually create all the lists and columns on the SharePoint site.

    Recently, I was working on a PowerShell script to validate user inputs, and I needed to check if strings contained special characters. This is a common requirement when validating usernames, passwords, or parsing data files. The challenge is that PowerShell treats many special characters differently since they have specific meanings in the language.
  • Using Show-ObjectTree to browse PowerShell Objects
    You can use Get-Member to discover all Methods and Properties when working with Variables. But browsing them in your PowerShell Terminal is easier using Show-ObjectTree. In this small blog post, I'm having a busy week and preparing for my WorkplaceNinjasNL session next week, I will show you how that cmdlet works :-)

    For security purposes, it may be beneficial to restrict Active Directory account logins to regular working hours.

  • Microsoft Graph PowerShell SDK V2.26.1 Remains Flawed
    The developers rushed out Version 2.26.1 of the Microsoft Graph PowerShell SDK to fix some obvious issues. Alas, problems persist in PowerShell SDK cmdlets, including licensing failures and an issue that prevents the Connect-MgGraph cmdlet from being able to obtain an access token from Entra ID. My advice is to stay with V2.25 until Microsoft resolves the problems and generates a new stable version of the SDK.

  • The not so simplified syntax of Where-Object in PowerShell
    PowerShell 3.0 introduced several notable improvements to its cmdlet library, with one of the most useful features in this release being the simplified syntax for the Where-Object cmdlet.

    Three years ago, I wrote a script to analyze the audit records generated for Teams meeting recordings.

All of which meant that considerable work was needed to revamp (rewrite) the script. Maybe you need to check any script that uses the Search-UnifiedAuditLog cmdlet too?

PuTTY vulnerability vuln-p521-bias in c/security@programming.dev
[–] pwshguy@programming.dev 1 points 1 year ago

If I understand correctly, the signatures generated by PuTTY aren’t perfectly random, so if someone got a hold of a bunch of keys from a server, they could figure out the pattern. It takes about 60 keys. This affects not just PuTTY, but also FileZilla, WinSCP, TortoiseGit, and TortoiseSVN.

In other words if you have NIST P-521 keys, or any others using 521-bit ECDSA, you should revoke them and generate new key pairs. After you update your software.

January 2024 monthly "What are you working on?" thread in c/programming_languages@programming.dev
[–] pwshguy@programming.dev 4 points 2 years ago

I installed some security cameras around my house and set up Shinobi using an old PC. Unfortunately the PC is too old to use the built-in detectors in Shinobi. So, I took my first dive into playing around with some image detectors.

I wrote some python to download the daily recording from old PC to a newer one with a 3080 GPU. Then checks the videos for people. It will then trim the videos to only include times were there are people in frame. It cut my the storage requirements by over 95%.

Guidance on developing locally with Azure Automation in c/powershell@programming.dev
[–] pwshguy@programming.dev 2 points 2 years ago

Just a heads up, I received confirmation from the product team that the AZUREPS_HOST_ENVIRONMENT environment variable is going away. They are moving the backend to containers. Also, the COMPUTERNAME one that was always "client" is going to change too. The COMPUTERNAME will now be "Sandbox-###" with # being random numbers. I started using the code block below in my runbooks to find if they are running in Azure or hybrid worker/locally. It accounts for the current and the updates that will be rolling out in the near future.

$isHybridWorker = $true
if (($env:computername) -eq "CLIENT") {
    $isHybridWorker = $false
}
elseif ($env:USERNAME -eq 'ContainerAdministrator') {
    $isHybridWorker = $false
}
