    Hyper-V is available as both the FREE Hyper-V Server 2012 and as a role in Windows Server 2012.

    If you are virtualising Windows Server workloads (and have licensed them correctly), Hyper-V is completely “free” – so save yourself a lot of money by NOT purchasing an additional virtualisation solution.

    Who wants one of these for free?

    8GB USB Memory Stick

    Before you all say “Me” – there’s a catch or two:

    Memory Keys 

    • Firstly you have to have an Irish (North or South) postal address – for me to send it to you.
    • Secondly you have to be willing to spend ten minutes of your time doing something for me.

    I have accidentally ordered too many memory sticks – and now they need a home to go to!

    I do have a finite number (more than three) – so I’ll give them away on a first come – first served basis.

    Email me if you’re interested & I’ll let you know what I need in return.
