I cooked my hard boiled eggs wrong for my entire life...

Just came across this article and what should I say? Shame on me.

 The 4 steps to hard-boiling eggs for breakfast, salads, or Easter eggs.

1) Place eggs in a saucepan or pot and cover with cold water.
 Eggs first, then water. Why? Because if you put the eggs in second,  they might crack as they fall to the bottom of the pan. It’s no fun to  learn this the hard way.Also, very fresh eggs are delicious fried or scrambled, but older eggs are actually easier to peel. Your best bet for hard-boiled eggs is to choose eggs you’ve had in the refrigerator for a week or two.

2) Put pan over high heat and bring water to a rolling boil. Remove pan from heat and cover.
 You want the water to come just to a boil, but not stay there. Eggs  exposed to high heat for a long time go through a chemical reaction that  turns the yolks green! So to answer the question “how long should I  boil eggs?” The answer is pretty much not at all. And because the eggs  don’t really cook in boiling water, some people prefer the term  “hard-cooked eggs” to hard-boiled eggs.

3) Let the eggs stand in the hot water for 14-17 minutes.
 How long you let the eggs stay in the water depends on how big the eggs  are and how hard you want them cooked. To cook small eggs to medium,  let them stand for 14 minutes. To cook extra-large eggs to medium, let  them stand for 17 minutes. (We’re talking about chicken eggs here.  You’re on your own with ostrich eggs.)

4) Drain eggs and put in a bowl filled with ice water.
 The ice water isn’t just a nice-to-have; it cools the eggs down and  prevents the green yolk problem. If you’re planning to peel the eggs,  like if you’re chopping them for egg salad, crack them slightly before  putting them in the ice water, and let them sit for an hour for maximum  ease of peeling.
