Try setting up a method instead of a constant to avoid issues with over-defining if you ever
need need a sub-class.

I have the bad habit of always using puts when I probably use print. As a a result, I was having trouble with the gems that were usable for colorizing my ToDo 3.0. I figured out a gem-free solution, using ANSI escape codes, and thought I'd share.

WARNING: don't be surprised if someone comes along and tells you this is the worst thing you could ever do. I have NO idea if it is a kosher solution, but it worked and it required VERY little change to my code. Additionally, this method works on the systems we have at DBC (and on mine) but I don't know if it is universal (I "think" it is).

A little set-up: I decided that I wanted to handle the color coding of priorities(and the keeping of the priorities) in my Todo class and not my TodoList class. Each todo keeps track of its own priority level, so I just modified the to_s method to include the color.

ANSI escape codes are used to send things to the output that aren't printed, not unlike the \ before the n of a new line. I'll show my code and then explai

When is it okay to have repeating words or phrases, and when is it most definitely not? The distinction is an important element in your writing style.

Now, of course, I’m talking about repeating specific words, the key words of the sentence or paragraph. I’m not talking about repeating words or phrases such as, “It is,” or “and the”.

To give you a good example of what I mean, read the following:

When I got to the bottom of the stairs, I saw that the stairs were high and steep. I took a deep breath and began to climb the stairs. When I reached the top of the stairs I looked around me.
You’ll note of course that the word stairs was used four times in a short paragraph. It just doesn’t sound right to do that - it grates somehow. When you come across this in your work, you need to change it.

So, the above paragraph would be better written as something like:
