✅ loveable chaos achieved 1 y/o Corgi-Aussie mix (left) 3 y/o Corgi-Chihuahua mix (right) It's so fun when they get rambunctious with each other!

Pre-ordered the Clicks Communicator today. Very excited for these to ship in Q4!

Returned to tinkering around with polyPoSh again this evening. v1.1.0 is available now on GitHub. Improved support for PowerShell installation on various Linux distributions and architectures, along with adding support for macOS. 🔗 github.com/griffeth-bar...

There have absolutely never been any mixed messages being sent whatsoever by software.

yes, yes, very good, join us.

It's true 😂 these are our two Corgi mixes and depending on the angle you look at them they're very goofy. Sometimes they're a Corgi in a trenchcoat, and sometimes they look nothing like Corgis. One is Australian Shepard Corgi and the other is Chihuahua Corgi.

Pick your topic. If the shoe fits! It's the same circle.

Venn diagram with circles so closely overlapping that they are functionally the same, showing that people who don't understand a specific thing are basically the same people who crash out about a specific thing.

Hm, that's an interesting one. For non-ms-store apps I don't know of a way that doesn't involve actually downloading at least a little bit the installer executable. Which I'm certain is a no-go at that scale. But I'm far from the most knowledgeable person on this.

$$packageName = "Microsoft.VisualStudioCode" $url = (winget show $packageName | Select-String 'Installer URL:\s*(http\S+)').Matches.Groups[1].Value $tmpExe = "$env:TEMP\winget_temp.exe" $iconOut = "$env:TEMP\$packageName.png" Invoke-WebRequest -Uri $url -OutFile $tmpExe -Headers @{ "Range" = "bytes=0-3145728" } Add-Type -AssemblyName System.Drawing [System.Drawing.Icon]::ExtractAssociatedIcon($tmpExe).ToBitmap().Save($iconOut) Remove-Item $tmpExe Write-Output $iconOut$

Yeah, that functionality is actually the next icon to the right. Icon: Play button Hotkey: F5 Behavior: Runs entire script Icon: Play button over piece of paper Hotkey: F8 Behavior: Runs selected code

Feels like with stuff like this, it's always dependencies. There are definitely modules I wish would support PowerShell 7.x -- give us the option of that sweet, sweet parallel operations support!

"Important: The modules described in this document use .NET Framework. This makes it incompatible with PowerShell 6.0 and later, which use .NET Core."

Ever needed to know how many users from various domains are in an Exchange/Online distribution group? Here's a little one-liner to show you just that. #PowerShell #ExchangeServer #ExchangeOnline

$get-distributiongroupmember -id 'group name' | % {$_.primarysmtpaddress.split('@')[1]} | group # Sample Output # # Count Name Group # ----- ---- ----- # 2 adomain.tld {adomain.tld, adomain.tld} # 182 bdomain.tld {bdomain.tld, bdomain.tld, bdomain.tld, bdomain.tld…} # 11 cdomain.tld {cdomain.tld, cdomain.tld, cdomain.tld, cdomain.tld…}$

Have you tried it as suggested?

In this image I have a function that (1) declares an ArrayList, (2) adds data to that ArrayList, (3) returns a single ArrayList with proof that it is an ArrayList.

>> function myFunc {
> param(
> $MyData
> )
>
> begin {
> # declare arrayList
> $list = [System.Collections.ArrayList]::new()
>
> # putting static data in that arrayList
> [void]$list.Add('ExistingItem1')
> [void]$list.Add('ExistingItem2')
> [void]$list.Add('ExistingItem3')
> }
> process {
> # putting user-provided data in that arrayList
> [void]$list.Add($MyData)
> }
> end {
> # returning that arraylist using the unary array expression
> return ,$list
> }
> }
>> $test = myFunc -MyData 'AddedItem1'
>> $test
ExistingItem1
ExistingItem2
ExistingItem3
AddedItem1
>> $test.GetType()

Yep! James is more an authority than I, by an eternally long shot, but I can confirm this most certainly works. Breaks the way many folks who live in PowerShell expect functions to behave (including me...), but definitely works.

function myFunc {

define a listArray of integers
[collections.arrayList]$array = 1..10

use the prepended comma to emit the entire listArray as
# the object instead streaming the integers themselves
# to the pipeline
,$array
}
(myFunc).GetType()

Last week I messed about with creating a simple admin tool launcher in PowerShell. ⚙️🛠️📜 #PowerShell #WindowsPresentationFramework

A screenshot of a Windows application containing three columns of different admin-related tools such as utility snap-ins such as certificate manager, control panel settings such as windows firewall, and obscure/more specific settings from the "God Mode" options in Windows. The window has a filter bar to search for tools as well as a context indicator showing what user the app is running as, along with buttons to launch the selected tool, launch a powershell session as a specific user, or exist the application. The GUI is built using WindowsPresentationFramework and XAML.

may i offer you some corgis in these trying times

I mean, if we want to joke about verbosity, PowerShell actually does it with fewer characters: ```powershell ni abc.py ``` `ni` is an alias of `New-Item` and since File is the default item type, you don't need to specify it. That said, no need to "bash" (lol) any language. There's room for both!

Yet another basic service manager for Windows, written in PowerShell. This is very rough and will need more attention from me down the road at some point. github.com/griffeth-bar... #PowerShell #MicrosoftWindows #WindowsServer

I'll take it!

Quick checking HSTS header for a website in PowerShell: ```powershell (iwr bsky.app -useb).headers['strict-transport-security'] # Sample Output # max-age=31536000; includeSubdomains ```

```powershell
(iwr https://bsky.app/ -useb).headers['strict-transport-security']

# Sample Output
# max-age=31536000; includeSubdomains
```

This isn't actually what I was doing, but an illustrative example to show how joining an array of strings for your LDAP Filter can make it just more readable and maintanable.
