: Authentication Failure

I am currently using Ubuntu and am 100% new to Unix. I have installed Ubuntu to program in C and will be using the "Learn C the Hard Way" online textbook (http://c.learncodethehardway.org/book/ex0.html). I attempted the section in the textbook meant for setting up your computer and the second command is causing me some problems.
The first command in the link above executes without issue but when I try and run the second command:
$ su -c yum groupinstall development-tools

it prompts me for my password and when I enter it, it says 

su: Authentication Failure

How do I fix this?

A:

Look again at the web page. You are trying, wrongly, to run a command for an RPM based Linux like Fedora. Instead, run the command that says:
For Debian based systems, like Ubuntu you should just have to install a few things using these commands:
$ sudo apt-get install build-essential

 Q:

What is the default scope of worksheets and cells and range?

When you just type worksheets() what is the default scope ActiveWorkbook or ThisWorkbook? For those who do not know these distinctions they are extremely important especially in Excel 2013 when you want macros to run when you switch to different workbooks.

A:

In a standard module an unqualified Worksheets() will always reference the ActiveWorkbook. In the ThisWorkbook module, the implicit qualifier is Me and that will reference the containing workbook.
Likewise, an unqualified Range() or Cells() (or Rows()/Columns()) in a standard module will reference the ActiveSheet, but in a sheet code module the implicit qualifier is Me, and will reference the corresponding worksheet.
Unqualified...       Where              Implicit Qualifier
--------------       --------------     -------------------
Worksheets(),        ThisWorkbook       Containing workbook (Me)
Sheets()             Any other module   Active workbook (via [_Global])

Range(), Cells(),    Sheet module       Containing sheet (Me)
Rows(), Columns(),   Any other module   Active sheet (via [_Global])
Names()

The easy way to avoid having to remember any of this is to always fully qualify any Worksheets, Sheets, Range, Cells, or Names reference.
