Super User Review of Hyper-V for Windows 8

September 17, 2012 by kronos. 10 comments

This weeks question of the week come from these two questions:

One of them asked by Graham Clark, and the other is a self post by myself.  This prompted me to do a more formal review of Microsoft’s Hyper-V for Windows 8.

What is Hyper-V for Windows 8?

Hyper-V for Windows 8 is really called Client Hyper-V.  It’s similar in many aspects to the Microsoft Server’s Hyper-V (2008 and the upcoming 2012).  What’s different about Client Hyper-V is that it was customized to fit the portable environments, such as laptops, that developer’s find themselves in.  What does Hyper-V do?

In brief, Hyper-V lets you run more than one 32-bit or 64-bit x86 operating system at the same time on the same computer. Instead of working directly with the computer’s hardware, the operating systems run inside of a virtual machine (VM).

Question of the Week #42: 42 Questions of Awesomeness!

September 10, 2012 by kronos. 0 comments

The number 42 is amazing, and so to honor Douglas Adams answer to live, the universe and everything, I have collected 42 amazing questions/answers that we haven’t featured yet.  These aren’t in any particular order, as they are all interesting or awesome in some way or another.

1 Storing hard drive near electric wireEver wonder if your hard drive could be ruined while being near electical lines well here’s the tl;dr answer:

In short, don’t worry about it, unless you’re working with some kind of industrial equipment with VERY high currents on that cable (the amount of interference emitted from a power cable is proportional to the current on it). Household currents are unlikely to be a problem.

2 What are PATH and other environment variables, and how can I set or use them? – Environment variable can be a powerful tool to use.  The answer is a great guide on the how’s what’s and why’s of environment variables within Windows.

3 Why do disks fragment? – With the advent of SSD’s and their completive prices there may come a day when fragmentation will become a thing of the past, but for now it’s something we need to deal with.  The answers still provide insight to the woe’s of the the past when it comes to disk drive fragmentations.

4 How does a CPU ‘know’ what commands and instructions actually mean? – There’s a lot of “magic” that goes on behind the scenes as you operate your computer.  All of this magic eventually ends up being assembly level instructions which in turn…  well that’s the question, and the answers are pretty good at explaining the basics.

5 What makes a laptop overheat? – Laptops are notorious for overheating, and this question/answer duo helps to try to explain what it is.
