Quick checking HSTS header for a website in PowerShell:
```powershell

# 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.

Had a cozy #Thanksgiving morning with both #Corgi pups lounging on my lap (feat. really wide camera angle). No complaints here!

MicroITX build in a Fractal Terra case with an AMD Ryzen 7 5700X, AMD Radeon RX 7800 XT, 64 GB RAM, and a few TB of NVMe SSD storage.
And the PlayStation 5 runs Orbis OS, based on FreeBSD not Linux 😉 though a PlayStation running something other than Orbis OS is definitely a cool thought.

Some of us are running PowerShell on our Linux machines. There are dozens of us!

Finally, I tried calling .NET directly:
```powershell
[System.IO.Compression.ZipFile]::ExtractToDirectory($path, $destPath)
```
This took 22s, which was another slight improvement.
```powershell
[System.IO.Compression.ZipFile]::ExtractToDirectory($path, $destPath)

Next, the same command but temporarily disabling the live progress bar:
```powershell
$progressPreference = 'SilentlyContinue'
Expand-Archive -Path $path -DestinationPath $destPath
$progressPreference = 'Continue'
```
This took around 25s -- much faster! This is where the bulk of time is wasted.

$progressPreference = 'SilentlyContinue'
Expand-Archive -Path $path -DestinationPath $destPath

First, just regular.
```powershell
Expand-Archive -Path $path -DestinationPath $destPath
```
It took around 1m 8s.
```powershell
Expand-Archive -Path $path -DestinationPath $destPath
```
It took around 1m 8s.

Nah, that's completely reasonable. There are plenty of well-known orgs with process and systems issues that allow stuff like that to happen. With all the complexity of technology and such, people and process are somehow always the most difficult part to get completely right.

Feels pretty good to me! I'm using the powershell-bin package from AUR which is currently at v7.5.3 on Garuda Linux. I haven't come across any major issues yet.

It's worth at least trying should you feel so inclined.

Yeah, the form factor can be extremely limiting for higher end builds. Luckily my daily driver is low powered (only a 5700X) enough to not need a secondary, but strong enough for what I do. Built this little guy 3 months ago and am loving the smaller form factor!

Ever considered keeping tabs on your #powershell profile to make sure no unexpected changes were made to it? Try PSProfileWatcher! v0.1.1 is available now.

You can usually just pipe its standard output to Out-File if you're just dealing with strings.
```powershell
Whatever-YoureDoing | Out-File -Path /path/to/file -Force
```
Hopefully that is helpful!

Nice post, Harm! `Get-Random` is fun! It's what I use to roll polyhedral dice using PowerShell in `Invoke-DiceRoll`.

Because of this, it looks like you can take a transitory step to enable AES without disabling RC4 but setting the bitmask to 0x1C.

Apparently, filling the "This account supports #Kerberos AES xxx bit encryption" checkboxes on user and computer objects in #ActiveDirectory doesn't just enable support for AES #encryption, but disables support for RC4 encryption (the prior default). I thought it would ADD the algo not REPLACE it.
