random stuff Bubba comes across - and needs to remember. 
Most modern virtualization software lets you add a disk (and hence: disk space!) to your virtual machines while the machine is powered on. That's great - but then the VM's operating system needs to be able to do something with it.
In Linux, that can be quite a chore. Especially if the disk running out of space is your / partition.... In this article, I'll show you what to do about that. And no, it's not scary. Almost.
Here you are, all proud that you finished your first Powershell script. Cool! Congrats. PAt yourself on the back!
Now try running it. Most likely you're getting a little pesky prompt telling you to run the script only if if you trust the publisher of the script, blah, blah blah. Great stuff - if you downloaded the thing from the Big Bad Internet - but VERY annoying if you want to run the script automatically (e.g. as a login script or the like). Of course I trust the publisher! I'm not THAT paranoid! So here's how to get around the prompt (drum roll, please): Use the ExecutionPolicy switch!
PowerShell -ExecutionPolicy Bypass -File <your_path_and_scriptname>
We needed to move the location of where the user profiles on a Windows 2008 R2 Server are stored from C: to D: . This turned out to be a bit more work than anticipated - hence this article.
All right, that title might have been a bit misleading.
What I want to talk about is the SPF - the Sender Policy Framework. And, to be more precise, what to do with it.
First off: What is it? It's a way to tell folks about who's allowed to send mail on your behalf. Ever recived mail from yourself telling you to buy Viagra? In most cases that wasn't your alter-ego (or your spouse) talking - it was a spammer posing as yourself. SPF aims to get rid of these nuisances.
