In one sentence, describe what the following article is about: A more modern technique is to clip each individual flight feather on the shaft right at the point where there are no longer any barbules. (The feathery protrusions growing from the quill, or shaft, are called barbs or barbules.)  Select the flight feather you wish to trim, and clip it carefully on the quill, below the barbules (the wide, soft part of the feather). Cut the quill just below the barbules — if you clip too close to the bird, you may hurt him. Never cut the shaft if it is dark in color — this is the blood supply that indicates it is a growing feather (or blood feather.) Clip only a few feathers at first, and don't clip more than you absolutely have to. Birds are very proud about their feathers, and over-clipping your bird may upset him. The old-fashioned way to clip a cockatiel's feathers is to cut all the flight feathers at once, so that the ends of the feathers create a straight line; however, this can leave sharp edges that can injure your bird.  Clip the group of feathers you intend to trim all at once, about halfway up the wide part of the feather – as if you were giving the bird a hair cut. Trim the feathers at an angle, to match the length of the covert feathers (the shorter, softer feathers on top.) After clipping four of your cockatiel's primary flights, let her loose for a “test flight.” If she can still attain lift, clip one more flight feather from each wing. Your bird should be able to control drift when released, so she can glide to the floor safely. She should not be able to lift off, however, or remain airborne.
Summary: Clip each flight feather individually. Clip using the traditional method. Do a test flight.

In one sentence, describe what the following article is about: Before you start coding your program, it will help to have some written material to refer to during the programming process. The design document outlines the goals of the program and describes the features in depth. This allows you to stay focused on the function the program.  The design document should discuss each of the features you want to include and how they will be implemented. The design document should also consider the user experience flow and how the user accomplishes his or her task using the program. Create a map for your program, indicating how the user gets from one part to another. A simple flowchart is usually perfectly fine for a basic program. The goals of the program will dictate the structure that you pick. Knowing which one of the following structures best relates to your program will help focus the development. This is the most simple type of program, and allows you to get comfortable with your programming language. Basically, a 1-2-3 program starts, asks for input from the user, and then displays a result. After the result is displayed, the program ends.  The next step after a 1-2-3 is a REPL (Read-Execute-Print Loop). This is a 1-2-3 program that goes back to 1 after displaying the output. Consider a Pipeline program. This is a program that transforms user input and runs continuously. This is a method good for programs that require little user interaction, such as an RSS reader. The program will be written as a series of classes that share a loop.
Summary: Write up a basic design document. Map out the program using rough sketches. Determine the underlying architecture of the program you are creating. Start with a "1-2-3" program.

In one sentence, describe what the following article is about: Easy lifestyle changes can make a big difference in the state of your skin later in life. For model beautiful skin, limit your exposure to the sun, maintain adequate hydration, and don’t smoke. These simple changes will benefit your body and your skin. For an easy way to reduce wrinkles, try sleeping on your back. Lines on your face caused by your pillow can become permanent over time, so try sleeping on your back to lessen the effect. If you can’t get a good night of sleep on your back, try to use pillows made of silk or satin, which lessens the lasting impressions of fabrics on your skin. Oils rich in antioxidants (such as coconut oil) will improve the quality of your skin by reducing the production of free radicals that lead to the visual signs of early aging. Apply oils to your skin each night after cleansing and before bed in order to reduce the appearance of fine lines and wrinkles. Laser skin resurfacing will help to reduce severe facial wrinkles, scars, and blemishes. A surgeon can use laser skin resurfacing to remove unwanted and damaged skin while simultaneously stimulating the growth of new collagen fibers, leading to skin that is smoother and firmer. For more information about laser skin resurfacing, consult your skin care professional or dermatologist. These are substances used by a physician that will aid in replacing lost volume in certain areas of your face. The benefit of these injections is that you will have substantial and long-lasting results. Ensure that any injectable filler that you use is FDA approved. Commonly used FDA approved fillers include hyaluronic acids, hydroxylapatite microspheres, poly-l-lactic acid, and polymethyl methacrylate microspheres/collagen. A trusted doctor, dermatologist, or skincare professional can provide advice regarding which filler may be best for you.
Summary:
Prevent the onset of wrinkles. Sleep on your back. Apply oils rich in antioxidants. Try laser skin resurfacing. Consider injectable fillers.
