JOYSTICK

A joystick is an input device consisting of a stick that pivots on a base and reports its angle or direction to the device it is controlling. Joysticks are often used to control video games, and usually have one or more push-buttons whose state can also be read by the computer. A popular variation of the joystick used on modern video game consoles is the analog stick.

The joystick has been the principal flight control in the cockpit of many aircraft, particularly military fast jets, either as a center stick or side-stick.

Joysticks are also used for controlling machines such as cranes, trucks, underwater unmanned vehicles, wheelchairs, surveillance cameras and zero turning radius lawn mowers. Miniature finger-operated joysticks have been adopted as input devices for smaller electronic equipment such as mobile phones.

Joysticks pull off a really neat trick. They take something entirely physical -- the movement of your hand -- and translate it into something entirely mathematical -- a string of ones and zeros (the language of computers). With a good joystick, the translation is so flawless that you completely forget about it. When you're really engaged in a game, you feel like you're interacting with the virtual world directly.

In this article, we'll find out how several common joystick designs handle this translation. As we'll see, the technology has evolved a great deal from the first game console designs to the sophisticated "force feedback" models available today.

KEYBOARD

The set of typewriter-like keys that enables you to enter data into a computer. Computer keyboards are similar to electric-typewriter keyboards but contain additional keys. The keys on computer keyboards are often classified as follows:

  alphanumeric keys -- letters and numbers

  punctuation keys -- comma, period, semicolon, and so on.

  special keys -- function keys, control keys, arrow keys, Caps Lock key, and so on.

The standard layout of letters, numbers, and punctuation is known as aQWERTY keyboard because the first six keys on the top row of letters spellQWERTY. The QWERTY keyboard was designed in the 1800s for mechanical typewriters and was actually designed to slow typists down to avoid jamming the keys. Another keyboard design, which has letters positioned for speed typing, is the Dvorak keyboard.

There is no standard computer keyboard, although many manufacturers imitate the keyboards of PCs. There are actually three different PC keyboards: the original PC keyboard, with 84 keys; the AT keyboard, also with 84 keys; and the enhanced keyboard, with 101 keys. The three differ somewhat in the placement of function keys, the Control key, the Return key, and the Shift keys.

In addition to these keys, IBM keyboards contain the following keys: Page Up,Page Down, Home, End, Insert, Pause, Num Lock, Scroll Lock, Break, Caps Lock, Print Screen.

There are several different types of keyboards for the Apple Macintosh. All of them are called ADB keyboards because they connect to the Apple Desktop bus (ADB). The two main varieties of Macintosh keyboards are the standardkeyboard and the extended keyboard, which has 15 additional special-function keys.

10 Tips to Maintain Health and Beauty

Beauty, health, and nutrition are all integrated. If you eat a balanced diet you will be able to maintain your physique and glowing beauty externally and good health internally. A balanced diet is one that provides all the nutrients you need, the right amount of proteins, carbohydrates, and fat.

To achieve goals you need to ensure a good balance in your diet, introduce variety into your meals, and practice moderation. The basis of nutrition lies in your height, weight, dimensions, and your daily energy needs. Once you know this you can compute what your daily calorific needs are and set goals for weight maintenance, gain, or loss. By regulating your diet you can be active as well as happy.

You must:

1. Eat sensibly. Include a variety of foods in your diet such that the 40 nutrients that are required by your body are present. Make use of a food pyramid and calorie chart to prepare tasty and nutritious meals. Follow the "Dietary Guidelines for Americans" issued each year.

2. Eat plenty of whole grains, fruits, and vegetables. They will supply you with essential vitamins, minerals, and protection from several diseases.

3. Maintain your weight at a healthy level. Successful weight management is one of the golden keys to good health. By doing is you will lower considerably the risk of many diseases like hypertension, diabetes, heart diseases, cancer, and osteoporosis.

4. Learn self control, eat moderate portions. The secret lies in eating everything but in small portions. Don't give way to gluttony or greed.

5. Make a time-table for your meals and how many calories will be in each meal. Never fast, starve yourself, or skip a meal. Eat when your body demands sustenance but not huge quantities.

6. Practice moderation. Good health does not lie in eliminating carbohydrates or fats. Include all your favorite foods but balance them with the rest of your diet. If you indulge your taste buds by eating pizza one day, then try and do so at lunch time, never eat pizza late at night. Ask for low fat cheese and healthy toppings. Eat just enough to satisfy your craving not all 12 slices. Get a few friends to share you sin. The days you indulge, eat sensibly the rest of the day--salads and fruits will help you make up for the binge.

7. Be sure your meals each day include all the food groups.

8. Plan to exercise every day. Either walk or take up aerobics, dancercise, or join a gym. Exercise will not just burn calories but put a glow into your skin, tone your muscles, and strengthen your bones. Exercise also removes accumulated toxins from your body.

9. Maintain a dairy in which you record your goals, and what you eat each day. Review your week objectively and create a table that shows at a glance what you did right and what you did wrong. This will help keep you on the right track.

10. Celebrate each victory. Give yourself a present or take yourself out every time you achieve a goal.

By eating healthy, one can live a complete and rounded life without diseases, reduce stress greatly, look and feel great, be happy from within and without, age well, produce healthy progeny, and live life to the fullest.

10 Tips To Reduce Stress

While you may not be able to solve the biggest stressors in your life, you can do something about many of the smaller stressors that "nickel and dime you to death." Here are some proven stress reducers you can implement in daily life to help:

1. Get up 15 minutes earlier each morning. That gives you a little more time to eat something, run back to get something you forgot, or enjoy a cup of coffee before heading out the door. If you drive to work, a 15 or 20 minute head start may decrease some of the traffic you face, and make the commute less stressful.
2. Prepare for mishaps. Make an extra copy of your house key and bury it in your neighbors' yard; make a second copy of your car key and tape it under your coworker's desk. Both may allow you to get home and inside the house if you loose your keys. If you do have to use them, pat yourself on the back for being smart.
3. Don't do something if you will have to lie about it afterwards. While this may seem obvious, the nagging guilt we feel often wears us down or makes us anxious about getting caught… Sure, it may be more time consuming to fax your resume to new job sites from Kinko's, but you don't have to worry about being caught.
4. Do something healthy for yourself. That could mean taking the stairs once a day instead of the elevator, picking one day a week to have a salad for lunch, or eating fresh fruit instead of a candy bar. What's the overall effect on your health? Maybe not much, but small steps lead to bigger ones, and doing something simple for your body is the best way to start.
5. Write it down. There is an old Chinese proverb that goes, "The palest ink is better than the most retentive memory." All those "Seven Secrets" tips are based on writing things down. Write down goals, errands, chores, due dates for projects and library books… Instead of just a "To Do" list, keep a "Have Done" list too. Move things over to that list after having completed them. At the end of the day, review how productive you were.
6. Do something special on a whim. Buy flowers for your partner unexpectedly. Sneak a small greeting card that says "I love you" into your child's lunch box. Bring donuts, bagels, or muffins to the office for others one morning. You get the picture. Someone else's smile and "Thanks" can sometimes make a bad day better.
7. Be willing to forgive others. Allowing others the right to make a mistake goes a long way toward forgiving yourself for mistakes. Assume that others are doing the best they can. Mark Twain once said, "Never attribute to malice what can easily be attributed to stupidity." This goes a long way toward doing the best you can as well.
8. Don't eat lunch at your desk. Get away to somewhere quiet or different if only for a 15 or 20 minute break.
9. Delegate new jobs. Say no to avoid additional responsibilities. Simplify. Put your best effort into a task, and ask yourself, "Is it really that important?" before you decide to do it over. Learn to ignore others' criticism sometimes.
10. Get up and stretch periodically. Twist side to side and bend front to back. Roll your head around to stretch your neck a bit. Trade shoulder rubs with a coworker. If you used to smoke, but have stopped, get up and take a break anyway when you feel the need to smoke. A quick trip to the water cooler, to a coworker's desk, or to the restroom doesn't provide the nicotine a cigarette used to, but it does give you the break and moment's respite a cigarette did.

TSUNAMI JAPAN 2011

On 11th Mac 2011, the day i'm leaving for semester break, world was shocked by Tsunami tragedy in Japan. Japan was strucked by a 8.9 magnitude earthquake from Japan that results into a giant killer Tsunami that washed away anything on his way either house, vehicles or civilians were destroyed. The tsunami is about 13 meters in height started from the coast of Oshika.
 

The 8.9 magnitude quake caused many injuries. It sparked fires and the wall of water, prompting warnings to people to move to higher ground in coastal areas.
The Philippines, Taiwan and Indonesia all issued tsunami alerts, reviving memories of the giant tsunami which struck Asia in 2004. The Pacific Tsunami Warning Center issued alerts for countries to the west and across the Pacfici as far away as Colombia and Peru.
There were several strong aftershocks. In Tokyo, buildings shook violently. An oil refinery near the city was on fire, with dozens of storage tanks under threat. In Tokyo four million homes are without power. A hotel collapsed in the city of Sendai and people were feared buried in the rubble.
Stunning TV footage showed the tsunami carrying the debris and fires across a large swathe of coastal farmland near the city of Sendai, which has a population of one million. The pictures suggested the death toll was going to rise.
Sendai is 300 km (180 miles) northeast of Tokyo and the epicentre at sea was not far away.
The Friday quake was the biggest since 1872, according to the Japan Meteorological Agency. It surpasses the Great Kanto quake of Sept. 1, 1923, which had a magnitude of 7.9, killed more than 140,000 people in the Tokyo area. Seismologists had said another such quake could strike the city any time. The 1995 Kobe quake caused $100 billion in damage and was the most expensive natural disaster in history. Economic damage from the 2004 Indian Ocean tsunami was estimated at about $10 billion.

Wifi Hotspot

Whats is Wifi Hotspot?

Wi-fi Hospot is a service that provides a whole new mobile lifestyle with wireless broadband internet access at selected public places such as shopping malls, coffee houses, hotels, hospitals, F&B outlets, colleges, airports and etc. The service offered is based on the standard WiFi technology which is IEEE 802.11 a/b/g. Customer cam simply log on at any Wi-fi Hospot and go online using laptop, tablet PC, PDA as well as mobile phone that equipped with a WiFi capabilities.

How Wi-Fi Works ?

Alike cell phones, a Wi-Fi network makes use of radio waves to transmit information across a network. The computer should include a wireless adapter that will translate data sent into a radio signal. This same signal will be transmitted, via an antenna, to a decoder known as the router. Once decoded, the data will be sent to the Internet through a wired Ethernet connection. As the wireless network will work as a two-way traffic, the data received from the Internet will also pass through the router to be coded into a radio signal that will be receipted by the computer wireless adapter.

Connect To Wi-Fi Hotspots

The process for connecting to a Wi-Fi hotspot works similarly on home, business and public wireless networks. With the profile (network name and encryption settings) applied on the wireless network adapter, you initiate the connection from your computer operating system (or software that was supplied with the network adapter). Paid or restricted hotspot services will require you to log in with a user name and password the first time you access the Internet.

Danger of Wi-Fi Hotspot.

Although few incidents of hotspot security issues are reported in the press, many people remain skeptical of their safety. Some caution is justified as a hacker with good technical skills can break into your computer through a hotspot and potentially access your personal data.

Taking a few basic precautions will ensure reasonable safety when using Wi-Fi hotspots. First, research the public hotspot service providers and choose only reputable ones who use strong security settings on their networks. Next, ensure you do not accidentally connect to non-preferred hotspots by checking your computer's settings. Finally, be aware of your surroundings and watch for suspicious individuals in the vicinity who may be reading your screen or even plotting to steal your computer.


Summary


Wi-Fi hotspots are becoming an increasingly common form of Internet access. Connecting to a hotspot requires a wireless network adapter, knowledge of the profile information of that hotspot, and sometimes a subscription to a paid service. Computers and Wi-Fi finder gadgets both are capable of scanning the nearby area for Wi-Fi hotspots, and several online services allow you find far-away hotspot locations. Whether using a home, business or public hotspot, the connection process remains essentially the same. Likewise, as with any wireless network, security issues for Wi-Fi hotspots need to be managed.
