Best and worst comment I've ever left in code, at a previous job:
"This will break in 73 years. If you're still using this at that point, you have much, much bigger problems."
Not sorry.

Some days I wonder if it would literally kill most developers to add comments.

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.

I've had the Sennheiser HBD 630s for about a month now and I tell you what, they're amazing in nearly every single way. The only complaint I have is the touch controls leave quite a bit to be desired. Otherwise, exceedingly happy with the purchase!

People always expect that I like smartphones and stuff because I've worked in IT/with tech for a long time. But it's quite the opposite. I despise touch screens, and very much so miss my blackberry.

If this is "mansplaining", I think I've had the wrong definition of the word for years.

Moving Beyond PSCustomObjects with PowerShell Classes
We’ve all probably been there. You’re working with some platform’s API and it returns you a veritable “bag” of properties in a JSON string or something similar.

Working with a CSV file of Microsoft Purview logs?
```powershell
$auditData = ipcsv yourPath | select -exp auditData | ConvertFrom-JSON
```
is a good friend to make the logs significantly more readable and usable.

To be clear, the real vulnerability here is human intelligence/attention or the lack thereof, not PowerShell itself.

Ah, yes, the long-respected and most effective way of communicating with others.
It's amazing to me how people manage to live their lives like this. I don't have the energy haha.

Well, well, well. Ended up using this yet again today. There's a reason it's worth making re-usable functions and hanging onto them!
Need to copy all the members of a #MicrosoftEntra group as direct members of another Entra group? This `Copy-EntraGroupMember` #PowerShell function can do that.

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.

RegEx and LDAP Filters are two great use cases for joining arrays of strings in PowerShell. Been building RegEx that way for a while, but did it with LDAP Filters today and found it quite nice!
