How do I explain how Anti-Virus protection works to a non-Super User?
I found this question which expalins a little in detail of how Anti-Virus softwares work exactly. But I just had a client ask me this, and I really couldn't give him a good, simple, easy to understand answer. Best thing I could come up with was that each virus has a specific "fingerprint" and the s…

Is there a way to move a column in between existing columns with drag-and-drop?
In Excel 2010, I want to move a column with some data to be in between two existing columns which also have data.

What's the difference between burning an ISO and copying a DVD's contents?
Is converting a DVD to an ISO, and then burning that ISO onto another DVD exactly the same thing as copying all the files from one DVD to another? What about if instead of copying to another DVD, I copied to a USB flash drive (i.e. DVD > USB), would it still be the same thing as DVD > ISO > USB? If…

My wife's Windows 7 (64-bit) box has suddenly developed a SMART "disk is bad" status.

Browser extension (or other software) to delay page load
The alt text to today's comic at xkcd.com (strip below) says: After years of trying, I broke this habit in a day by decoupling the action and the neurological reward. I set up a simple 30-second delay I had to wait through, in which I couldn't do anything else, before any new page or chat client wo…

I'm thinking of adding a solid state drive (SSD) to my existing Windows 7 installation. I know I can (and should) move my paging file to the SSD: Should the pagefile be placed on SSDs? Yes.

I have the following lines at the bottom of my .vimrc.local: However, whenever I open a new file, both these values are set to their defaults (72 and 2, respectively) and not my custom settings.

SandForce SSD encryption - security and support
I'm currently thinking about buying a ThinkPad X201 and equip it with a SSD drive. Now, to protect my data I always used Linux with LUKS full disk encryption on my laptops.
