February 24, 1955 To October 5, 2011






Steven Paul Jobs was born on February 24, 1955 in San Francisco, California. His unwed biological parents, Joanne Schieble and Abdulfattah Jandali, put him up for adoption. Steve was adopted by Paul and Clara Jobs, a lower-middle-class couple, who moved to the suburban city of Mountain View a couple of years later.
The Santa Clara county, south of the Bay Area, became known as Silicon Valley in the early 1950s after the sprouting of a myriad of semi-conductor companies. As a result, young Steve Jobs grew up in a neighborhood of engineers working on electronics and other gizmos in their garages on weekends. This shaped his interest in the field as he grew up. At age 13, he met one the most important persons in his life: 18-year-old Stephen Wozniak, an electronics wiz kid, and, like Steve, an incorrigible prankster.

Five years later, when Steve Jobs reached college age, he told his parents he wanted to enroll in Reed College — an expensive liberal arts college up in Oregon. Even though the tuition fees were astronomical for the poor couple, they had promised their son's biological parents he would get a college education, so they relented. Steve spent only one semester at Reed, then dropped out, as he was more interested in eastern philosophy, fruitarian diets, and LSD than in the classes he took. He moved to a hippie commune in Oregon where his main activity was cultivating apples.

A few months later, Steve returned to California to look for a job. He was hired at the young video game maker Atari, and used his wages to make a trip to India with one of his college friends, in order to 'seek enlightenment'. He came back a little disillusioned and started to take interest in his friend Woz's new activities.
Woz, whose interest in electronics had grown stronger, was regularly attending meetings of a group of early computer hobbyists called the Homebrew Computer Club. They were the real pioneers of personal computing, a collection of radio jammers, computer professionals and enlightened amateurs who gathered to show off their latest prowess in building their own personal computer or writing software. The club started to gain popularity after the Altair 8800 personal computer kit came out in 1975.

The knowledge that Woz gathered at the Homebrew meetings, as well as his exceptional talent, allowed him to build his own computer board — simply because he wanted a personal computer for himself. Steve Jobs took interest, and he quickly understood that his friend's brilliant invention could be sold to software hobbyists, who wanted to write software without the hassle of assembling a computer kit. Jobs convinced Wozniak to start a company for that purpose: Apple Computer was born on April 1, 1976.

The following months were spent assembling boards of Apple I computers in the Jobses' garage, and selling them to independent computer dealers in the area. However, Wozniak had started work on a much better computer, the Apple II — an expandable, much more powerful system that supported color graphics. Jobs and Wozniak knew deep down it could be hugely successful, and therefore Jobs started to seek venture capital. He eventually convinced former Intel executive turned business angel Mike Markkula to invest $250,000 in Apple, in January 1977. Markkula was a big believer in the personal computing revolution, and he said to the young founders that, thanks to the Apple II, their company could be one of the Fortune 500 in less than two years.

Although Markkula was a bit too optimistic about Apple's growth rate, he was right that the company quickly became an American success story. Because of its beautiful package, ease of use, and nifty features, the Apple II crushed most of its competition and its sales made the Apple founders millionaires. The biggest surge in sales came after the introduction of VisiCalc, the first commercially successful spreadsheet program: hundreds of thousands of Americans, whether they be accountants, small business owners, or just obsessed with money, bought Apple IIs to make calculations at home.

In the wake of Apple's success, its investors decided it was time to go public. The IPO took place in December 1980, only four years after the company was started. Steve Jobs's net worth increased to over $200 million, at age 25.
Apple's success attracted the attention of the computer giant IBM, which until then was still only selling mainframe computers to large companies. A crash project was started and in August 1981, the IBM PC entered the personal computer market. It was the biggest threat yet to Apple, whose reputation was being put into question after the flop of the Apple III in 1980. Most hopes rested on a business computer project, called the Lisa.






Steve Jobs was a big believer in the Lisa computer initially. It was he who came up with the name. Indeed, in 1978, his ex-girlfriend from high school Chrisann Brennan gave birth to a little girl, who she named Lisa. Steve denied paternity, although it was ovious to everyone who knew him that he was the father, given the on-and-off relationship he still had with Chrisann at the time. Jobs refused to give any money to Chrisann, despite the millions he had accumulated at Apple. While in denial, he came up with the name Lisa for the new computer Apple was building.

The following year, a tour of the computer research lab Xerox PARC made a huge impression on him. The scientists who worked there had invented a number of breakthrough technologies that would mark the industry for the coming decades, including the graphical user interface (GUI) and the mouse, Ethernet, laser printing and object oriented programming. Jobs became obsessed with the GUI which was a lot easier to use than the command-line interfaces of the day, which required any PC user to learn a computer language. He insisted the Lisa had a GUI and a mouse, too.

However, because of his hot temper and his relative inexperience in technology or management, Steve Jobs was thrown out of the Lisa project. He felt absolutely crushed by this decision. As a revenge, he took over a small project called Macintosh, a personal computer that was supposed to be a cheap appliance, 'as easy to use as a toaster'. In 1981, Steve Jobs became head of the Macintosh project, and decided to make it a smaller and cheaper version of the Lisa, complete with a GUI of folders, icons and drop-down menus, and a mouse.
The three years it took to develop Macintosh were some of the most productive and intense for Steve Jobs. He formed a small group of dedicated, young, brilliant engineers who stood fully behind his vision of a computer 'for the rest of us'. They saw themselves as 'pirates' against the rest of Apple, 'the Navy'. The team antagonized both the Apple II group and the Lisa group, because the Mac was competitive of both. Yet in 1983, after it became clear the Lisa was turning into another major flop for Apple, all of the company's hope started to rest on the Macintosh. Steve was supported in his mission by John Sculley, Apple's new CEO whom he hired in 1983 to help him run the company and groom him into a future chief executive.

                              


On January 24 1984, after Apple had run a very memorable TV commercial for the SuperBowl ('1984'), Steve Jobs introduced Macintosh at the company's annual shareholders meeting. The product was launched in great fanfare and for the first few months, it was very successful.

However, by early 1985, sales were plummeting, but Steve Jobs refused to acknowledge it and continued to behave as if he had saved Apple. This created a lot of tension within the company, especially between Steve and the CEO, John Sculley, who used to be very close but now stopped talking to one another.
In May 1985, Steve Jobs started trying to convince some directors and top executives at Apple that Sculley should go. Instead, many of them talked to Sculley, who took the matter to the board of directors. The board sided with Sculley and a few days later, announced a reorganization of the company where Steve Jobs had no operational duties whatsoever — he was only to remain chairman of the board.

Steve was aghast: Apple was his life, and he was effectively kicked out of it. After four months spent traveling and trying out new ideas, he came back in September with a plan: he would start a new computer company aimed at higher education, with a small group of other ex-Apple employees. When Apple learned of the plan, they declared they would sue him as he was taking valuable information about the company to compete with it. As a result, Steve Jobs resigned in September 1985, and sold all but one of his Apple shares, in disgust. He went ahead with his plan anyway, and incorporated NeXT. Apple dropped its lawsuit a few months later.

Steve aimed at the highest possible standards for his new NeXT machine: he wanted the best hardware, built in the world's most automated factory, and running the most advanced software possible. He decided that the computer's operating system, NeXTSTEP, would be based on UNIX, the most robust system in the world , used by the military and universities— but that it would also be as easy to use as a Macintosh,with its own GUI. NeXTSTEP would allow for object oriented programming, another breakthrough from Xerox PARC, that made writing software much faster and more reliably. These ambitious plans put off the release date of the computer — called the NeXT Cube — to October 1988.

When it came out, the NeXT Cube was indeed a great machine. But it didn't sell — it was late, and way too overpriced: universities has asked for a $3,000 computer, and Steve Jobs had built a $10,000 workstation. After two years of very low sales, NeXT launched the cheaper NeXT Station, and expanded its target to businesses, in addition to higher ed. It didn't work: the number of NeXT computers sold each month remained in the hundreds. The company was bleeding money and all its co-founders left one after the other, as well as its most prominent investor, Texan billionaire Ross Perot. By 1993, NeXT had to give up its entire hardware business to become a niche software company. Steve Jobs had failed, and he was devastated. He started focusing less on work, and more on his wife Laurene (who he married in 1991) and his newborn son, Reed.

                                  

To understand how Steve Jobs got out of his nadir, let's go back eight years earlier, in late 1985. At the time, George Lucas, who was in the middle of an expensive divorce, was selling the computer graphics division of his Lucasfilm empire. Steve Jobs had millions in the bank, after having sold all his Apple stock, and was interested. In early 1986, he bought the small group of computer scientists, and incorporated it as Pixar. The founders of Pixar, Ed Catmull and Alvy Ray Smith, had gotten together in the late 1970s with a common vision of making films using computer animation only. But they also knew no computer was powerful enough at the time, and they would have to hold out for a couple decades before their dream could materialize.

For the first five years of Pixar, Steve Jobs set a goal for the company to sell high-end computer graphics workstations for institutions, such as hospitals or even the army. The animations group led by John Lasseter was very small at the time, and only survived because it provided good publicity for the power of the Pixar rendering software. Steve Jobs understood this when the studio won an Academy Award for its short movie 'Tin Toy' in 1989. However, just like NeXT's, sales of Pixar hardware were microscopic, and the company went software-only in 1990.
Pixar then became a software company, developing the RenderMan 3D rendering software. Its animation business was kept alive because it was the only one that brought some cash in, with various 3D TV commercials for consumer brands. However a decisive contract changed everything: in 1991, Disney signed with Pixar for making a full-feature computer-animated movie. The script had to be fully approved by both parties, and the very hands-on head of Disney animation Jeffrey Katzenberg halted the production several times out of creative disagreements with John Lasseter and his team. But in 1995, the movie was finally starting to take form, and Steve Jobs became increasingly enthused by it.



Although he had used his personal money to fund Pixar for nine years, Jobs had never been implicated that much in the company, which was always more of a 'hobby' to him compared to NeXT. But by 1995, NeXT had more or less tanked, whereas Pixar was obviously going to benefit widely from the Disney marketing machine and make a hit with Toy Story. Steve understood this new momentum full well: he planned to take Pixar public the week following the release of the movie, in November 1995. He was right, and Toy Story's box-office success was only surpassed by the Pixar stock's success on Wall Street. Steve Jobs, who owned 80% of the company, saw his net worth rise to over $1.5 billion — five times the money he had ever made at Apple in the 1980s!

Business wasn't all sunshine and roses at Apple. In the decade following Steve's departure, the computer maker had milked all the cash it could from the Macintosh and its successors, surfing on the wave of the desktop publishing revolution that the Mac and the laser printer had made possible. But in 1995, after Microsoft had released Windows 95, which was a pale but working copy of the Mac OS, sales of Macintosh computers started plummeting.

A new CEO, Gil Amelio, arrived in early 1996 to save the company. He cut costs, got rid of a third of the workforce, and decided that instead of writing a new, modern operating system from scratch to compete with Window, it was better for Apple to acquire one. Eventually, Amelio chose to buy NeXTSTEP, NeXT's operating system — and Steve Jobs convinced him to buy the whole company, for a whopping $400 million. The deal was made in December 1996: Steve Jobs was back at the company he founded.


The Amelio-Jobs cooperation didn't last long, though: Apple lost $700 million in the first quarter of 1997, and the board decided to get rid of its CEO. Jobs effectively organized a board coup with the complicity of his billionaire friend Larry Ellison, and after a tenure that lasted exactly 500 days, Amelio was gone. In August 1997, Jobs took the stage at Macworld Boston to explain his plan for Apple: he had gotten rid of the old board of directors, and made a deal with Microsoft to settle patent disputes and invest $150 million in the struggling Silicon Valley icon. One month later, on September 16, 1997, Jobs accepted to become Apple's interim CEO.

The few months after Steve Jobs came back at Apple were among the hardest-working in his life. He later told his biographer Walter Isaacson that he was so exhausted, he couldn't speak when he came home at night (remember he was also running a thriving Pixar simultaneously). He reviewed every team at Apple and asked them to justify why they were important to the future of the company. If they couldn't, their product would get canceled, and there was a high probability they'd have to leave, too. Jobs also brought with him his executive team from NeXT, and installed them in key positions.

Critics started to believe in Steve Jobs's ability to run Apple when he unveiled his first great product, the iMac. Introduced in May 1998, it was Apple's first truly innovative product since the original Macintosh of 1984. Its translucent design blew away the whole PC industry, which had failed to produce anything but black or beige boxes for over a decade. Moreover, it was a hot seller, and played a key role in bringing back tons of developers to the Mac platform. Design innovations continued throughout 1998 and 1999 with the colored iMacs and the iBook, Apple's consumer notebook. After three years in charge, Steve Jobs had brought Apple back to its status of cool tech icon.

At Macworld in January 2000, Steve Jobs made two significant announcements: first, he demoed Aqua, the graphics-intensive user interface that Apple would use in its next-generation operating system derived from NeXTSTEP, Mac OS X. Second, he announced he had accepted the Apple board's offer, and became the company's CEO, dropping the 'interim' from his title. It was not an obvious choice because he remained CEO of Pixar, too. Mac OS X had not shipped yet, though, and would take another year to ship.

The simple fact that such a massive OS transition happened is a technical feat in itself. The Mac OS X team worked very hard and released six major version of the system every year or so, between 2001 and 2007, each time with more stability, rapidity, and features. Although Steve Jobs buried Mac OS 9 on stage in 2002, most observers acknowledge that the transition from the old Mac OS to OS X was really finished only in 2005, with the release of Mac OS X 10.4 Tiger. The continuous improvement of Mac OS X and the powerful core technologies and development tools it provided proved key in the Digital Hub strategy that Steve Jobs described in January 2001.

Once Apple had been resurrected by the iMac, Steve Jobs started focusing on ways to make the company's shrinking marketshare (around 5% of PCs) grow. He decided to use Apple's unique knowledge of making both the hardware and the software to do just that: not only would Macs be very powerful and attractive machines, but they would also run software that no Windows PCs could. His first move was to bet on what he called 'desktop video', the ability to shoot and edit personal movies on your Mac. He was convinced that desktop video would be as big a deal as desktop publishing had been in the 1980s, and in 1999, he introduced the iMac DV and a digital movie editing software, iMovie, to pioneer that concept.

                                   


The iMac DV was a hit, but desktop video failed to catch on as Jobs had hoped. After a much introspection, in 2000, the Apple executive team came up with a new paradigm for the Mac that would set the company's destinies for the coming decade. They took the idea of desktop video and decided to expand it to the other consumer digital devices that were rapidly becoming mainstream at the time. Apple would write software for the Mac to edit and store all the new digital content that consumers created — and these apps would be so powerful, delightful and easy to use, that they would entice PC users to switch to the Mac. The Digital Hub strategy was born. Steve Jobs explained it to the Apple community at Macworld in January 2001, the same day he unveiled the 2nd and 3rd of the iApps: iDVD, to shares iMovies with family and friends on DVDs; and iTunes, a digital jukebox software. Other iApps would follow: iPhoto in 2002, GarageBand in 2004, and iWeb in 2006.
In many ways, the juggernaut that Apple became was shaped by very smart decisions that Jobs and his executive team took in the crucial 2000-2001 timeframe. We've talked of Mac OS X and the Digital Hub strategy, a crucial product and a crucial strategy that were both unveiled in January 2001.

A third key decision was taken in 2000 and unveiled in mid-2001: that of creating a fully-owned retail channel, the famous Apple retail stores. Although it is easy to approve of this strategy in retrospect, it was far from an obvious choice back in May 2001, when the first two retail stores were inaugurated. PC maker Gateway was shutting down its own retail stores one after the other, and the analysts consensus at the time was that niche player Apple would burn precious money in this economic downturn on a foolish and dated idea. On the other hand, Steve Jobs explained that only in an environment fully controlled by Apple, with Apple-trained staff and only Apple-compatible products, could the superiority of Macs be fully appreciated by consumers.

Finally, it was in 2000 that Jobs started realizing his mistake of betting only on digital movies, and reoriented the company's efforts to another media: music. Digital music file-sharing service Napster was at the peak of its popularity, and all the young people were not spending their time shooting movies, but rather downloading and listening to MP3 music files. iTunes was born out of that realization, but there was a problem: although there were great digital camcorders to run in conjunction with iMovie, and awesome digital cameras too, digital music players mostly sucked — not to mention their universal ugliness.

That's why, in March 2001, Steve Jobs started a crash development program to develop an Apple-branded MP3 player before that year's holiday season: the iPod was born. On October 23, 2001, he introduced this cute none digital device to a small group of journalists in the company's campus auditorium. The tagline was '1,000 songs in your pocket', and there was great emphasis on its symbiosis with the iTunes app. But no one in the room, Jobs included, had any clue how important it would turn out to the company's future.

Tags of HTML 5-Part 1st

There are following tags in HTML5:-

(1)bdi: It stands for Bi-directional Isolation.

Example:-

<html>
    <head><title>bdi tag in html5</title>
    <style type="text/css"">
    bdi
    {
        color:orange;
        font-size:20px;
    }
    </style>
        </head>
    <body>
<ol>
<li>User <bdi>homerjay</bdi>: 1601 posts</li>
<li>User <bdi>msimpson</bdi>: 335 posts</li>
<li>User <bdi>إيان</bdi>: 195 posts</li>
<li>User إيان: 195 posts</li>
<li>User <bdi>moe</bdi>: 2 posts</li>
</ol>
    </body>
</html>
In the above example, we have shown how to use bdi element. bdi tag is usually used to embed text which is different in direction to english text. For Example : Arabic text is written from right to left, which is contrary to english text written from left to right. In order to embed Arabic text along with english we can use bdi tag.
        In the above example, in third li element we have used bdi element to show arabic text in sam direction to english tag. In 4th li element we have not used bdi element and that is why the arabic text is on right side.


(2)bdo: It stands for Bi-directional override. 
Example:-
<!DOCTYPE html>
<html>
    <head>
<title>bdi tag in html5</title>
 
    </head>
    <body>
<!-- Switch text direction -->
<p>This text will go left to right.</p>
<p><bdo dir="rtl">This text will go right to left.</bdo></p>
    </body>
</html> 
It is used to override the current directionality of text. It causes the directionality of the characters to be ignored in favor of the specified directionality. 
Possible values for text directions are-
  • ltr: Indicates that the text should go in a left-to-right direction.
  • rtl: Indicates that the text should go in a right-to-left direction.
  • auto: The browser decides which direction based on the element's content.
 
(3)mark:It defines marked text.

Example:-

<!DOCTYPE html>
<html>
<body>

<p>Do not forget to buy <mark>milk</mark> today.</p>

</body>
</html>

Use this tag,if you want to highlight parts of your text.

(4)meter:It defines a scalar measurement within a known range, or a fractional value. This is also known as a gauge.

Example:-

<!DOCTYPE html>
<html>
<body>

<p>Display a gauge:</p>
<meter value="5" min="0" max="10">5 out of 10</meter><br>
<meter value="0.6">60%</meter>

<p><strong>Note:</strong> The meter tag is not supported in Internet Explorer.</p>

</body>
</html>

(5)progress:It represents the progress of a task.

 Example:-

<!DOCTYPE html>
<html>
<body>

Downloading progress:
<progress value="22" max="100">
</progress>

<p><strong>Note:</strong> The progress tag is not supported in Internet Explorer 9 and earlier versions.</p>

</body>
</html>


What is HTML 5?

HTML5 is a markup language used for structuring and presenting content for the World Wide Web and a core technology of the Internet. It is the fifth revision of the HTML standard and, as of December 2012, is a candidate recommendation of the World Wide Web Consortium.

The declaration which is required:-
<!DOCTYPE html> 

Above declaration  represents that the page is in HTML5.

Below is the simple example:
<!doctype html>

<html>

<head>
All the js and css files are included in this section.
</head>

<body>
content of the page is in this section
</body>

</html>

But all major browsers (Safari, Chrome, Firefox, Opera, Internet Explorer) continue to add new HTML5 features to their latest versions.

Note:-The first web browser, Mosaic, was introduced in 1993. A year later Netscape, based on Mosaic, was introduced and the net began to become popular. HTML was used in both browsers, but there was no "standard" HTML until the introduction of HTML 2.0.

HTML 2.0 was first published in 1995. HTML 3.0 was published two years later and 4.01 two years after that.

What is Silicon Valley?

Silicon Valley, industrial region around the southern shores of San Francisco Bay, California, U.S., with its intellectual centre at Palo Alto, home of Stanford University. Silicon Valley includes northwestern Santa Clara county as far inland as San Jose, as well as the southern bay regions of Alameda and San Mateo counties. Its name is derived from the dense concentration of electronics and computer companies that sprang up there since the mid-20th century, silicon being the base material of the semiconductors employed in computer circuits. The economic emphasis in Silicon Valley has now partly switched from computer manufacturing to research, development, and marketing of computer products and software.

The term Silicon Valley was coined by Ralph Vaerst, a successful Central California entrepreneur. Its first published use is credited to Don Hoefler, a friend of Vaerst's, who used the phrase as the title of a series of articles in the weekly trade newspaper Electronic News. The series, entitled "Silicon Valley in the USA", began in the paper's issue dated January 11, 1971. The term did not become widely known and used, however, until the early 1980s, at the time of the introduction of the IBM PC and numerous related hardware and software products to the consumer market. Valley refers to the Santa Clara Valley, located at the southern end of San Francisco Bay, while Silicon refers to the high concentration of companies involved in the making of semiconductors (silicon is used to create most semiconductors commercially) and computer industries that were concentrated in the area. These firms slowly replaced the orchards and related agriculture and food production companies which gave the area its initial nickname - the "Valley of Heart's Delight."

This blog is a tribute to Sir Steve Jobs.

Steven Paul Jobs was born on 24 February 1955 in San Francisco, California, to students Abdulfattah Jandali and Joanne Schieble who were unmarried at the time and gave him up for adoption. He was taken in by a working class couple, Paul and Clara Jobs, and grew up with them in Mountain View, California.

He attended Homestead High School in Cupertino California and went to Reed College in Portland Oregon in 1972 but dropped out after only one semester, staying on to "drop in" on courses that interested him.He took a job with video game manufacturer Atari to raise enough money for a trip to India and returned from there a Buddhist.

Back in Cupertino he returned to Atari where his old friend Steve Wozniak was still working. Wozniak was building his own computer and in 1976 Jobs pre-sold 50 of the as-yet unmade computers to a local store and managed to buy the components on credit solely on the strength of the order, enabling them to build the Apple I without any funding at all.

The Apple II followed in 1977 and the company Apple Computer was formed shortly afterwards. The Apple II was credited with starting the personal computer boom, its popularity prompting IBM to hurriedly develop their own PC. By the time production of the Apple II ended in 1993 it had sold over 6 million units.

Inspired by a trip to Xerox's Palo Alto Research Center (PARC), engineers from Apple began working on a commercial application for the graphical interface ideas they had seen there. The resulting machine, Lisa, was expensive and never achieved any level of commercial success, but in 1984 another Apple computer, using the same WIMP (Windows, Icons, Menus, Pointer) interface concept, was launched. An advert during the 1984 Super Bowl, directed by Ridley Scott introduced the Macintosh computer to the world (in fact, the advert had been shown on a local TV channel in Idaho on 31 December 1983 and in movie theaters during January 1984 before its famous "premiere" on 22 January during the Super Bowl).

In 1985 Jobs was fired from Apple and immediately founded another computer company, NeXT. Its machines were not a commercial success but some of the technology was later used by Apple when Jobs eventually returned there.

In the meantime, in 1986, Jobs bought The Computer Graphics Group from Lucasfilm. The group was responsible for making high-end computer graphics hardware but under its new name, Pixar, it began to produce innovative computer animations. Their first title under the Pixar name, Luxo Jr. (1986) won critical and popular acclaim and in 1991 Pixar signed an agreement with Disney, with whom it already had a relationship, to produce a series of feature films, beginning with Toy Story (1995).

In 1996 Apple bought NeXT and Jobs returned to Apple, becoming its CEO. With the help of British-born industrial designer Jonathan Ive, Jobs brought his own aesthetic philosophy back to the ailing company and began to turn its fortunes around with the release of the iMac in 1998. The company's MP3 player, the iPod, followed in 2001, with the iPhone launching in 2007 and the iPad in 2010. The company's software music player, iTunes, evolved into an online music (and eventually also movie and software application) store, helping to popularize the idea of "legally" downloading entertainment content.

In 2003, Jobs was diagnosed with pancreatic cancer and underwent surgery in 2004. Despite the success of this operation he became increasingly ill and received a liver transplant in 2009. He returned to work after a six month break but eventually resigned his position in August 2011 after another period of medical leave which began in January 2011. He died on 5 October 2011.
