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.

First blog post of 2026 is here. PowerShell is a class act! For newcomers to PowerShell, did you know that PowerShell has classes?

#PowerShell
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.

This might be the weirdest and most interesting thing I've done w/ PowerShell. I learned about NTFS Alternate Data Streams & shoved a PowerShell script, database engine, & database into a single .ps1 file with zero external dependencies.

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.

"I just like being antagonistic"

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.

Thinking about revising my agent instruction to include "if I ask about making a new #powershell module, always respond with 'someone else probably did that already'"

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!

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.
Screenshot of demonstrative PowerShell code: ```powershell # ONE-LINER --------------------------------------------------------------------------------------- Get-ADUser -LDAPFilter "(&(objectCategory=person)(objectClass=user)(!(userAccountControl:1.2.840.113556.1.4.803:=2))(|(memberOf=CN=GroupName,OU=Groups,DC=example,DC=com)(extensionAttribute1=SYNC))(!(|(cn=*svc*)(cn=*service*)(description=*DoNotSync*))))" # JOINING ARRAY OF STRINGS ------------------------------------------------------------------------ $ldapFilter = @( "(&", "(objectCategory=person)", # users "(objectClass=user)", # users "(!(userAccountControl:1.2.840.113556.1.4.803:=2))", # enabled users "(|(memberOf=CN=GroupName,OU=Groups,DC=example,DC=com)", # in GroupName group "(extensionAttribute1=SYNC))", # with extensionAttribute1 value "SYNC" "(!(|(cn=*svc*)(cn=*service*)(description=*DoNotSync*)))", # manual exclusions ")" ) -join '' Get-ADUser -LDAPFilter $ldapFilter ```

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!

If using #PowerShell makes you a loser, then I don't want to be a winner! It's an incredibly powerful and extensible language that has brought me much enjoyment and success both outside and inside of my career.
