Clean way to create a hash with 3 levels of nesting which creates levels if they don't exist
by mndoci in Programming Languages

This is what I do now

h = Hash.new { |h1, k1| h1[k1] = Hash.new { |h2, k2| h2[k2] = {} } }

Although it works, it looks kind of ambiguous. Maybe there is a better way to do the same thing?

Normal Healthy Thyroid Levels Vs. Dangerous Levels
by svn in Health
There is much confusion as to what a normal thyroid level is. Since there is more than one type of thyroid disease, thyroid levels that are considered dangerous differ between each type. Hence, there are tests performed that determine what an individual's thyroid level is, and proper treatment can be given before such dangerous levels cause serious health issues. The FactsThere are two types of

What Raises HDL Levels & Lowers LDL Levels?
by Demo24 in Health
High density lipo-proteins (HDL) cholesterol is often simply referred to as "good cholesterol." This is because HDL cholesterol carries out the beneficial task of binding to "bad cholesterol" (LDL), taking it to the liver to be passed from the body. Maintaining high levels of HDL cholesterol is beneficial and an important part of maintaining good cardiovascular health. DietPeople who are seekin

How to Lower Bad Cholesterol Levels & Improve Good Cholesterol Levels
by NesuD in Health

If your bad cholesterol is too high, you are at increased risk of heart disease. The American Heart Association has a health-heart program that recommends diet and exercise to lower bad cholesterol and improve good cholesterol numbers.Difficulty:Moderately Challeng

How to Lower Bad Cholestrol Levels & Improve Good Cholestrol Levels
by Surya in Health
Bad cholesterol levels are ideally at 100 or lower while good cholesterol levels are ideally around 50 or higher. The goal of good health is low bad cholesterol levels and relatively high good cholesterol levels. Bad cholesterol, or LDL cholesterol, is harmful to health and the heart while good cholesterol, or HDL cholesterol, is good for health and promotes a healthy heart.Difficulty:ModerateIn

How do I loop through all levels of a data structure to extract all data when I don't know how many levels there will be?
by patrickcarver in Programming Languages

I need to extract data from a structure and put it into a list, but I don't know how many levels the structure has.

For each level, I can call level.children(), if there are no levels below the current one, it returns [], if there are, it returns [object, object, ...], on each of which I can call children() on again.


What to Eat With High Sugar Levels & High Cholesterol Levels
by Mai72 in Health
Foods abundant in saturated fat raise LDL levels, which is the bad cholesterol. Foods rich in polyunsaturated and unsaturated fats prevent LDL cholesterol production and increase levels of HDL (good) cholesterol.
High sugar levels are a result of the pancreas' inability to produce sufficient or recognizable insulin, which facilitates a buildup of glucose in the blood. To avoid diabetes, hear

CO and C2 Levels
by Tennessee in Hobbies, Games & Toys
Carbon monoxide, or CO, and diatomic carbon, or C2, are two gases containing carbon. Public safety campaigns exist in order to prevent dangerous exposure to carbon monoxide, as it can be a deadly gas. Diatomic carbon occurs infrequently on earth. It is important to keep carbon monoxide levels below a certain point. Measuring devices can help with this. COCO, or carbon monoxide, is a toxic gas.
