In Chapter 2, you learned how to create a simple web server using only Node. In this chapter, we will recreate that server using Express. This will provide a jumping-off point for the rest of the content of this book and introduce you to the basics of Express.
Scaffolding is not a new idea, but many people (myself included) were introduced to the concept by Ruby. The idea is simple: most projects require a certain amount of so-called “boilerplate” code, and who wants to recreate that code every time you begin a new project? A simple way is to create a rough skeleton of a project, and every time you need a new project, you just copy this skeleton, or template.
Ruby on Rails took this concept one step further by providing a program that would automatically generate scaffolding for you. The advantage of this approach is that it could generate a more sophisticated framework than just selecting from a collection of templates.
Express has taken a page from Ruby on Rails and provided a utility to generate scaffolding to start your Express project.See more

Ajoint disease that is aggravated by mechanical stress, osteoarthritis is characterized by the degeneration of cartilage that lines joints or by osteophyte formation (that is, the formation of bony outgrowths), which results in pain, stiffness, and sometimes loss of function of the affected joint, reported the American Medical Association Home Medical Encyclopedia.1
“Osteoarthritis occurs in almost all people over the age of 60 and [most], but not all of them, exhibit symptoms,” the publication said. “Various factors lead to the development of osteoarthritis earlier in life, including an injury to a joint or a congenital joint deformity. Osteoarthritis may occur with rheumatoid arthritis. Severe osteoarthritis affects 3 times more women than men.” (Rheumatoid arthritis is a systemic disease involving chronic and progressive inflammatory involvement of joints as well as atrophy of muscles.)
Patients with osteoarthritis complain of pain, swelling, creaking, and stiffness of one or more joints. These conditions can interfere with walking and dressing, and they can disrupt sleep.See more

or everyday good health, start with a three-quarter dropperful (0.62 ml) or six sprays of the 100% goji berry extract twice daily. Many people will notice positive effects quickly, often within a matter of a few days. To achieve maximum benefit, however, you should allow a full six months of use, so that goji juice may work to bring your body back to the perfectly balanced state known to physicians as homeostasis.
Listen to your body. If, after the first month of use, you feel that your results are suboptimal, you may increase your daily dose to twelve sprays twice daily of the 100% goji berry extract per day. Remain at the twelve sprays twice daily dosage level for a full week, and, if necessary, add an additional ounce (30 ml) the following week. You can increase to 1½ dropperfuls up to three times daily. You may take your daily serving all at once, or you may split it into as many portions as you like.
Goji juice is a food, so there is no danger of toxicity. However, you should always consult your physician or health advisor before starting to take any dietary supplement.See more

Telecommunication: Any transmission and/or emission and reception of signals representing signs, writing, images and sounds or intelligence of any nature by wire, radio, optical or other electromagnetic systems.
Whether you are converting to Voice over IP or already have, network administrators will be required to handle a collection of issues of a more traditional nature and connect to the outside world. So even though we may have embraced the future, it is difficult to divorce ourselves entirely from the past. For the foreseeable future, an understanding of analog and digital circuit-switched technology, telephony wiring, and the tried-and-true methods for connecting to ISPs is necessary. For example, one of the most popular circuits sold is still a T-1. In addition, data from the International Telecommunication Union indicates that while the growth in Internet use and devices accessing the Internet is significant, it does not signal the death knell of more traditional fixed services. This data is shown in Figure2-1.See more

Thalassemia (Mediterranean anemia) is a group of inherited disorders in which there is a defect in the production of hemoglobin, the oxygen-carrying substance that synthesizes in the bone marrow for incorporation into red blood cells, explained the American Medical Association Home Medical Encyclopedia. Many of the red blood cells are fragile and quickly break up, leading to hemolytic anemia. This condition is prevalent in people originating from the Mediterranean region, the Middle East, and Southeast Asia.1
“The hemoglobin of healthy people contains two pairs of globins or protein chains known as alpha chains and beta chains,” the publication said. “In thalassemia, synthesis of either of the chains is reduced, causing an imbalance between alpha and beta chains in much of the hemoglobin that is produced.”
Abnormal hemoglobin production in this disorder is caused by inheritance of a defective gene; usually the production of beta chains is disturbed, leading to beta-thalassemia. When people inherit one defective gene for the disease, they are said to have beta-thalassemia minor, or thalassemia trait, which is never severe.See more
