This little PowerShell script you can check how familiar you are with all the built-in aliases in PowerShell V2 CTP2.
For each alias there are 7 cmdlet names to choose from. There are 10 questions, and at the end of the quiz you can review your results and optionally run the quiz again.
You need to have PowerShell V2 CTP2 installed for the script to run.
Good luck :)
SAPIEN Technologies has released a new COM component named ActiveXPoSH (included in PrimalScript 2007 script editor).

Before the beta release of Microsoft System Center Virtual Machine Manager 2008, there was only one option for automating management of Hyper-V virtual machines—Windows Management Instrumentation (WMI). In this webcast, you learn how to automate the most common management tasks, how to create a delegation model using Windows Authorization Manager, and where the power of WMI can pick up where Virtual Machine Manager leaves off. In addition, the Hewlett-Packard Windows Server 2008 Academy team shares their experience automating the deployment of 600 virtual machines in less than three hours using WMI and Windows PowerShell.
Presenters: Dung Hoang Khac, Principal Consultant, HP, and Aric Bernard, Senior Technology Consultant, HP

The old function return duplicate names when the enumeration has two names with the same value, for example:
PS > Get-EnumValues Microsoft.PowerShell.ExecutionPolicy
Name Value
---- -----
Unrestricted 0
RemoteSigned 1
AllSigned 2
Restricted 3
Restricted 3
Here is the modified version of the function:
function Get-EnumValues([type]$type){
[enum]::getNames($type) | select @{n="Name";e={$_}},@{n="Value";e={$type::$_.value__}} | ft -auto
}
And the results:
PS > Get-EnumValues Microsoft.PowerShell.ExecutionPolicy Name Value ---- ----- Unrestricted 0 RemoteSigned 1 AllSigned 2 Restricted 3 Default 3

In response to Steve's Scripting/Sysadmin Meme
How old were you when you started programming?
I was 27 when I started to write HTML/ASP pages.
What was your first machine?
My first real computer was Windows 95 PC. When I was 12 (I think), my uncle gave me a Texas Instruments (I can't remember the model name) but at that time I wasn't a computer geek.
What was the first real script you wrote?
Looping through ADO recordset and populating Active Server Pages (ASP).
What scripting languages have you used?
JavaScript/DHTML, VBScript/JScript.
Now that PowerShell is out all other scripting languages are set aside.
What was your first professional sysadmin gig?
I started as a sysadmin in a government institution back in 1998 and I'm still holding that position (aside from one year in which I left and returned).
If you knew then what you know now, would have started in IT?
Yes. Ever since I have been in the field I have found that being in IT brings out the best in me.
If there is one thing you learned along the way that you would tell new sysadmins, what would it be?
Learn to script! Knowing to script is your sysadmin added value, sorts of a 'super sysadmin' if you will. You'll be able to do magic when your boss wants something that the GUI can't provide.
What’s the most fun you’ve ever had scripting?
Every day that passes with Windows PowerShell scripting is a great deal of fun. I learn something new every day.
Who am I calling out?
My son heard all the alien beeps and asked me for this one, the Popcorn tune. I couldn't say no :)

Windows PowerShell is arguably one of the coolest things to happen to developers and administrators alike. Harness the power of the Microsoft .NET Framework from the command line and learn how to write scripts in no time at all. With Windows PowerShell, we leverage your current .NET Framework experience to turn you into one heck of a good scripter.

In PowerShell v1 you could import comma separated CSV files only. That's not a problem anymore in CTP2. The Import/Export CSV cmdlets got enhanced and now they support a new -delimiter parameter:
PS > get-help import-csv -Parameter delimiter -Delimiter [<char>] Specifies the delimiter that separates the property values in the file that is being imported. The default is a com ma (,). Enter a character, such as a semicolon (;). Required? false Position? 2 Default value , Accept pipeline input? false Accept wildcard characters? false
Note that the delimiter is limited to a single character.
# Export processes to a space separated csv file
PS > get-process | export-csv -delimiter " " -path processes.csv
# Convert csv files: comma separated to tab separated
PS > import-csv test.csv | export-csv -del "`t" -p test1.csv
Five tones:
$notes = 900,1000,800,400,600
$duration = 400,400,400,400,1600
0..($notes.length-1) | % {[console]::beep($notes[$_],$duration[$_]) }
Spaceship Siren:
1..10 | % { 370..470 | % { [console]::beep($_,5) }}
Talking alien :)
900,500,1000,800,400,600,1200,300,200,500,1100,300 | %{[console]::beep($_,100)}
CTP2 Alien:
1..20 | foreach { $rnd = (Get-Random -min 0 -max 20)*100 if($rnd -eq 0) { sleep -m 10 } else { [console]::beep($rnd,100) } }
One major change to the Get-Process/Get-Service cmdlets in CTP2 is the ability to get objects from remote computers via a new parameter, computerName (or -c for short). You can map process/service objects to their computer by the machineName member.
