A Brief Biography of Thomas Edison Biography Thomas Edison. People often say Edison was a genius. He answered, "Genius is hard work, stick-to-it-iveness, and common sense." Thomas Alva Edison was born February 11, 1847 in Milan, Ohio (pronounced MY-lan). In 1854, when he was seven, the family moved to Michigan, where Edison spent the rest of his childhood. "Al," as he was called as a boy, went to school only a short time. He did so poorly that his mother, a former teacher, taught her son at home. Al learned to love reading, a habit he kept for the rest of his life. He also liked to make experiments in the basement. Al not only played hard, but also worked hard. At the age of 12 he sold fruit, snacks and newspapers on a train as a "news butcher." (Trains were the newest 8
way to travel, cutting through the American wilderness.) He even printed his own newspaper, the Grand Trunk Herald, on a moving train. At 15, Al roamed the country as a "tramp telegrapher." Using a kind of alphabet called Morse Code, he sent and received messages over the telegraph. Even though he was already losing his hearing, he could still hear the clicks of the telegraph. In the next seven years he moved over a dozen times, often working all night, taking messages for trains and even for the Union Army during the Civil War. In his spare time, he took things apart to see how they worked. Finally, he decided to invent things himself. After the failure of his first invention, the electric vote recorder, Edison moved to New York City. There he improved the way the stock ticker worked. This was his big break. By 1870 his company was manufacturing his stock ticker in Newark, New Jersey. He also improved the telegraph, making it send up to four messages at once. During this time he married his first wife, Mary Stilwell, on Christmas Day, 1871. They had three children -- Marion, Thomas, Jr., and William. Wanting a quieter spot to do more inventing, Edison moved from Newark to Menlo Park, New Jersey, in 1876. There he built his most famous laboratory. He was not alone in Menlo Park. Edison hired "muckers" to help him out. These "muckers" came from all over the world to make their fortune in America. They often stayed up all night working with the "chief mucker," Edison himself. He is sometime called the "Wizard of Menlo Park" because he created two of his three greatest works there. The phonograph was the first machine that could record the sound of someone's voice and play it back. In 1877, Edison recorded the first words on a piece of tin foil. He recited the nursery rhyme "Mary Had a Little Lamb," and the phonograph played the words back to him. This was invented by a man whose hearing was so poor that he thought of himself as "deaf"! 9
Starting in 1878, Edison and the muckers worked on one of his greatest achievements. The electric light system was more than just the incandescent lamp, or "light bulb." Edison also designed a system of power plants that make the electrical power and the wiring that brings it to people's homes. Imagine all the things you "plug in." What would your life be like without them? In 1885, one year after his first wife died, Edison met a 20-year-old woman named Mina Miller. Her father was an inventor in Edison's home state of Ohio. Edison taught her Morse Code. Even when others were around, the couple could "talk" to each other secretly. One day he tapped a question into her hand: would she marry him? She tapped back the word "yes." Mina Edison wanted a home in the country, so Edison bought Glenmont, a 29- room home with 13-1/2 acres of land in West Orange, New Jersey. They married on February 24, 1886 and had three children: Madeleine, Charles and Theodore. A year later, Edison built a laboratory in West Orange that was ten times larger than the one in Menlo Park. In fact, it was one of the largest laboratories in the world, almost as famous as Edison himself. Well into the night, laboratory buildings glowed with electric light while the Wizard and his "muckers" turned Edison's dreams into inventions. Once, the "chief mucker" worked for three days straight, taking only short naps. Edison earned half of his 1,093 patents in West Orange. But Edison did more than invent. Here Edison could think of ways to make a better phonograph, for example, build it with his muckers, have them test it and make it work, then manufacture it in the factories that surrounded his laboratory. This improved phonograph could then be sold throughout the world. Not only did Edison improve the phonograph several times, but he also worked on X-rays, storage batteries, and the first talking doll. At West Orange he also worked on one of his greatest ideas: motion pictures, or "movies." The 10
inventions made here changed the way we live even today. He worked here until his death on October 18, 1931, at the age of 84. By that time, everyone had heard of the "Wizard" and looked up to him. The whole world called him a genius. But he knew that having a good idea was not enough. It takes hard work to make dreams into reality. That is why Edison liked to say, "Genius is 1% inspiration and 99% perspiration." 11
Poetry Bachpan se hasrat thi.. Ab to jawani bhi so gayi, Chah meri bachapan ki dhoomil si ho gayi, Man ki khwaishein man me hi kho gayi, Aj meri haalat kabhi aisi na hoti-- Ki dar dar ki thokar na kha kar mai rota, Kash! Mujhe bhi insaan samjha hota!! Chun chun ke kachda ye bachpan tha beeta, Beeta wo sukh ab jawani bhi beeta, Padhne ka shaukh bas shaukh hi reh gaya, Samay ki dhaar me ab sab kuchh hi beh gaya, Soch kar tadapta hu,soch kar hu rota.. Kash! Mujhe bhi insaan samjha hota! Mujhe bhi insaan samjha hota!! Jisne abhi tak dekhi na duniya - Ya kaho duniaydaari, Sab chahte hain paane ko beta, Koi na kehta ki beti hai pyari, Kya galati thi uski jo saja mili use.. Sayad wo beti thi 'ajanma bechari'!! Kya uska man nahi tadapta hoga ki - Kash mai bhi khelti ma ki god me, Mai bhi dekhti is duniya ko, Apne pita ki god me, Par aho! Bhagya nhi hai uska, Kyunki ishwar ki pyari hogi ishwar ko pyari.. 12

Story NEVER QUIT : THREE FEET FROM GOLD A short story... One of the most common cause of failure is the habit of quitting when one is overtaken by temporary defeat. Evey person is guiltu of this mistake at one time or another. A man once thought of DIG GOLD AND GROW RICH. He had never heard that more gold has been mined from brains of men than ever been taken from earth. He staked a claim and went to work with pick and shovel. After a week of labour, he was rewarded by the discovery of shining ore. He needed machinery to bring the ore to the surface. Finally, he arranged money from his relatives and bought a machine. The first car of ore was mined, and shipped. A few more ore cars of ore would clear the debts he had taken. Then would come the big killing in profit. But then something happened! The vein of gold ore disappeared! They had come to the end of the rainbow and the pot of gold was no longer there. They drilled on desperately trying to pick up the vein again-all to no avail. Finally they decided to QUIT. They sold the machinery to a junk man for few hundred dollars. Some junk men are dumb, but not this one! He called in a mining engineer to look at the mine and do a little calculating. The engineer advised that the project had failed, because the owners were not familiar with fault lines. His calculations showed that the vein would be found JUST THREE FEET FROM WHERE THE MAN HAD STOPPED DRILLING! That is exactly where it was found. The junk man took millions of dollars in ore from the mine, because he knew enough to seek expert counsel before giving up. The common mistake which we all do in our life is that we QUIT when we don t achieve anything in first attempt. Life will go on throwing more and more 17
opportunities towards us, just we have to grab that. The BURNING DESIRE, SELF DETERMINATION AND SELF CONFIDENCE makes un UNSTOPPABLE. Therefore, Arise, Awake and Stop not till you achieve your Goal... Sibani Panda 2 nd Year, CSE Regd no. 1401292122 18
The Lighter Side Whatsapp! A story behind the scene ------------------------------------------------------------------------------------------- In today's world, we are very much addictive to WhatsApp. As of September 2015, WhatsApp had a user base of up to 900 million, making it the most globally popular messaging application. We all are very much familiar with all the features of WhatsApp. Basically it uses the Internet to send text messages, images, video, user location and audio media messages to other users using standard cellular mobile numbers, as well as calling facilities has been introduced in WhatsApp. So let's have an eye over the development process of Whatsapp, the most popular messaging app across the world. WhatsApp was founded in 2009 by Brian Acton and Jan Koum. Both of them were ex- employees of Yahoo. After Koum and Acton left Yahoo! in September 2007, they travelled to South America just for a break from work. At one point of time they applied for a job at Facebook but Facebook didn't hire them. For the rest of the following years Koum relied on his $400,000 savings from Yahoo. After purchasing an iphone in January 2009, he realized that the seven-month-old App Store was about to spawn a whole new industry of apps. He started visiting his friend, Alex Fishman where they discussed "...having statuses next to individual names of the people," but this was not possible without an iphone developer. So Fishman introduced Koum to Igor Solomennikov, a developer in Russia that he had found on RentACoder.com. Koum almost immediately chose the name "WhatsApp" because it sounded like "what's up", and a week later on his birthday, on February 24, 2009, he incorporated WhatsApp Inc. in California. However, early WhatsApp kept crashing or getting stuck and at a particular point. Koum felt like giving up and looking for a new job, upon which Brian Acton encouraged him to wait for a "few more months". 19
In June 2009, Apple launched push notifications, which let the app developers ping users when they were not using an app. Koum updated WhatsApp so that each time the user changed their statuses, it would ping everyone in the user's network. WhatsApp 2.0 was released with a messaging component and the active users suddenly swelled to 250,000. During this time Brian Acton was still unemployed while managing another unsuccessful start-up. Koum visited to Acton and he decided to join in the company. In October, Acton persuaded five ex-yahoo friends to invest $250,000 in seed funding, and as a result, he was granted co-founder status and a stake. He officially joined on November 1. After months at beta stage, the application eventually launched in November 2009 exclusively on the App Store for the iphone. Koum then hired an old friend, Chris Peiffer, who lived in Los Angeles, to make the BlackBerry version of WhatsApp, which arrived two months later. WhatsApp was switched from a free to paid service to avoid growing too fast, mainly because there was primary cost for sending verification texts to new users. In December 2009 WhatsApp for the iphone was updated to send photos. By early 2011, WhatsApp was in the top 20 of all apps in Apple's U.S. App Store. In April 2011, the founders agreed to take $7 million from Sequoia Capital on top of their $250,000 seed funding. By February 2013, WhatsApp's user base had swollen to about 200 million active users and its staff to 50. Sequoia invested another $50 million, valuing WhatsApp at $1.5 billion. In a December 2013 blog post, WhatsApp claimed that 400 million active users use the service each month. On February 19, 2014, months after a venture capital financing round at a $1.5 billion valuation, Facebook announced it was acquiring WhatsApp for US$19 billion, its largest acquisition to date. With 65 million active users, about 10% of the total worldwide users, India is the largest single country in terms of number of users. In January 2015, WhatsApp was the most globally popular messaging app with more than 600 million active users. In April 2015, 20
WhatsApp reached 800 million active users. By September 2015, the user base had grown up to 900 million. Let's have a look on the technical aspects of WhatsApp. WhatsApp uses a customized version of the open standard Extensible Messaging and Presence Protocol (XMPP). Upon installation, it creates a user account using one's phone number as the username (Jabber ID: [phone number]@s.whatsapp.net). WhatsApp software automatically compares all the phone numbers from the device's address book with its central database of WhatsApp users to automatically add contacts to the user's WhatsApp contact list. In January 2015, WhatsApp introduced a voice calling feature; this helped WhatsApp to attract a completely different segment of the user population. Multimedia messages are sent by uploading the image, audio or video to be sent to an HTTP server and then sending a link to the content along with its Base64 encoded thumbnail (if applicable) to the recipient. WhatsApp follows a store and forward mechanism for exchanging messages between two users. When a user sends a message, it first travels to the WhatsApp server where it is stored. Then the server repeatedly requests the receiver acknowledge receipt of the message. As soon as the message is acknowledged, the server drops the message; it is no longer available in database of server. WhatsApp server keeps the message only for 30 days in its database when it is not delivered (when the receiver is not active on WhatsApp for 30 days).
