byte + byte = int… why?
...
The third line of your code snippet:
byte z = x + y;
actually means
byte z = (int) x + (int) y;

How to implement a ConfigurationSection with a ConfigurationElementCollection
...
The previous answer is correct but I'll give you all the code as well.
Your app.config should look like this:

It recursively calls main() 771 times.
In the beginning, m[0] = 7709179928849219.0, which stands for C++Suc;C. In every call, m[0] gets doubled, to "repair" last two letters. In the last call, m[0] contains ASCII char representation of C++...
How do I use extern to share variables between source files?
...ler is informed that a
variable exists (and this is its type); it does not allocate the
storage for the variable at that point.
A variable is defined when the compiler allocates the storage for
the variable.
You may declare a variable multiple times (though once is sufficient);
you may only defin...
Clone only one branch [duplicate]
... do not point into the history of the branch are not fetched.
Git actually allows you to clone only one branch, for example:
git clone -b mybranch --single-branch git://sub.domain.com/repo.git
Note: Also you can add another single branch or "undo" this action.

Enum “Inheritance”
...
This is not possible. Enums cannot inherit from other enums. In fact all enums must actually inherit from System.Enum. C# allows syntax to change the underlying representation of the enum values which looks like inheritance, but in actuality they still inherit from System.enum.

UIView frame, bounds and center
...ed on Stanford CS193p course. Credits goes to @Rhubarb.
Using the frame allows you to reposition and/or resize a view within its superview. Usually can be used from a superview, for example, when you create a specific subview. For example:
// view1 will be positioned at x = 30, y = 20 starting t...
