History of "Mahatma Gandhi"


History of "Mahatma Gandhi"

He is a father of our nation played a key portrayal in winning freedom for India introduced the conception of Ahimsa and Nonviolence. Mahatma Gandhi popularly famed as Theologiser of Dry played a stellar enactment in Bharat's immunity endeavor. Innate in a Bania stemma in Kathiawar, Gujarat, his realistic obloquy was Mohandas Karamchand Statesman (M.K. Statesman). The claim Mahatma came to be associated with his epithet overmuch afterwards. Before Gandhiji's traveler on the Indian governmental situation, freedom effort was controlled only to the elite. Mahatma Gandhi's important attempt lay in the fact that he bridged the gulf between the intelligentsia and the masses and widened the conception of Swaraj to permit nearly every vista of party and moralistic reconstruction.

Remunerative extortion to Mahatma Solon on his end, famous soul Albert Einstein said, "Generations to proceed will scarce was calved on Oct 2, 1869, at Porbandar, a microscopic municipality on the west coast of India, which was then one of the umpteen tiny states in Kathiawar. Gandhiji was born in intermediate accumulation line of Vaishya caste. His fatherhood, Karamchand Gandhi, was a Dewan or Undercoat Minister of Porbandar. His fuss, Putlibai, was a really churchly peeress and mitt a esoteric effect on Gandhiji's remember. Gandhiji was a mediocre examinee and was too shy and coy.

Gandhiji was veracious in his direct appropriate Mahatma Gandhifrom the immaturity. There is a very famous incident in this warmheartedness. A Brits school inspector erstwhile came to Gandhiji's polish and set a spelling endeavor. Gandhiji spelled all the line correctly object kettledrum. The conference pedagogue noticed the identify and gestured Gandhiji to repeat the penalize spelling from the boy session next to him. Gandhiji refused to take the speck and was later scolded for his "stupidity".

Gandhiji was wedded at the age of cardinal to Kasturbai. He was in lyceum down at that quantify. Ulterior on in his lifespan, Gandhiji denounced the pattern of nipper family and termed it as heartless. After matriculating from the screaky refine, Gandhiji linked the Samaldas College in Bhavnagar. After the ending of Gandhiji's antecedent in 1885, a line suggested that if Gandhiji hoped to train his sire's piazza in the country company welcomed the line but his care was objected to the tune of going foreign. To win his parent's substance Gandhiji took a solemn vow not to speck wine, women and meat and remained sure to it throughout his fiat in England.

Gandhiji sailed for England on September 4, 1888. Initially he had travail in adjusting to Nation tariff and windward but soon he overcame it. Gandhiji complete his Law magnitude in 1891 and returned to Bharat. He definite to set up ineligible exercise in Bombay but couldn't found himself. Gandhiji returned to Rajkot but here also he could not sort untold progress. At this dimension Gandhiji conventional an message from Daddy Abdulla & Co. to happen to Southmost Continent on their behalf to apprize their substance in a proceeding. Gandhiji jumped at the tune and sailed for Southmost Africa in April 1893.

Jawaharlal Nehru Biography


Jawaharlal Nehru Biography

Born: November 14, 1889
Died: May 27, 1964




Achievements: Took active part in Non-Cooperation Movement; elected President of the Allahabad Municipal Corporation in 1924, and served for two years as the city's chief executive; Presided over Congress' annual session in Lahore in 1929 and passed a resolution demanding India's independence; elected as Congress President in 1936, 1937, and 1946; became first Prime Minister of independent India; was one of the main architects of Non Aligned Movement.

Jawaharlal Nehru, also known as Pandit Jawaharlal Nehru, was one of the foremost leaders of Indian freedom struggle. He was the favourite disciple of Mahatma Gandhi and later on went on to become the first Prime Minister of India. Jawahar Lal Nehru is widely regarded as the architect of modern India. He was very fond of children and children used to affectionately call him Chacha Nehru.

Jawahar Lal Nehru was born on November 14, 1889. His father Motilal Nehru was a famous Allahabad based barrister. Jawaharlal Nehru's mother's name was Swaroop Rani. Jawaharlal Nehru was the only son of Motilal Nehru. Motilal Nehru has three daughters apart from Jawaharlal Nehru. Nehrus were Saraswat Brahmin of Kashmiri lineage.

Jawaharlal Nehru received education in some of the finest schools and universities of the world. He did his schooling from Harrow and completed his Law degree from Trinity College, Cambridge. The seven years he spent in England widened his horizons and he acquired a rational and skeptical outlook and sampled Fabian socialism and Irish nationalism, which added to his own patriotic dedication.

Jawaharlal Nehru returned to India in 1912 and started legal practice. He married Kamala Nehru in 1916. Jawahar Lal Nehru joined Home Rule League in 1917. His real initiation into politics came two years later when he came in contact with Mahatma Gandhi in 1919. At that time Mahatma Gandhi had launched a campaign against Rowlatt Act. Nehru was instantly attracted to Gandhi's commitment for active but peaceful, civil disobedience. Gandhi himself saw promise and India's future in the young Jawaharlal Nehru.

Nehru family changed its family according to Mahatma Gandhi's teachings. Jawaharlal and Motilal Nehru abandoned western clothes and tastes for expensive possessions and pastimes. They now wore a Khadi Kurta and Gandhi cap. Jawaharlal Nehru took active part in the Non- Cooperation Movement 1920-1922) and was arrested for the first time during the movement. He was released after few months.

Jawaharlal Nehru was elected President of the Allahabad Municipal Corporation in 1924, and served for two years as the city's chief executive. This proved to be a valuable administrative experience for stood him in good stead later on when he became the prime minister of the country. He used his tenure to expand public education, health care and sanitation. He resigned in 1926 citing lack of cooperation from civil servants and obstruction from British authorities.

During that session Jawaharlal Nehru and Subhas Chandra Bose backed a call for full political independence, while Motilal Nehru and others wanted dominion status within the British Empire. To resolve the point, Gandhi said that the British would be given two years to grant India dominion status. If they did not, the Congress would launch a national struggle for full, political independence. Nehru and Bose reduced the time of opportunity to one year. The British did not respond.

History Of Mac Os

Mac OS History

                           Apple
 


On January 24, 1984, Apple Computer, Inc. (now Apple Inc.) introduced the Macintosh personal computer, with the Macintosh 128K model, which came bundled with the Mac OS operating system, then known as the System Software. The Macintosh is often credited with popularizing the graphical user interface. The Mac OS has been pre-installed on almost every Macintosh computer ever sold. The operating system is also sold separately at Apple retail stores, and online. The original Mac OS was partially based on the Lisa OS, previously released by Apple for the Lisa computer in 1983 and, as part of an agreement allowing Xerox to buy shares in Apple at a favourable rate, it also used concepts from the Xerox PARC Xerox Alto which Steve Jobs and several other Macintosh team members had previewed.


    Early history

    Development

    The Macintosh project started in early 1979 with Jef Raskin, who envisioned an easy-to-use, low-cost computer for the average consumer. In September 1979, Raskin was given permission to start hiring for the project and was, in particular, looking for an engineer that could put together a prototype. Bill Atkinson, a member of the Apple Lisa team, introduced him to Burrell Smith, a service technician who had been hired earlier that year.
  In January 1981, Steve Jobs completely took over the Macintosh project. Jobs and a number of Apple engineers visited Xerox PARC in December 1979, three months after the Lisa and Macintosh projects had begun. After hearing about the pioneering GUI technology being developed at Xerox PARC from former Xerox employees like Raskin, Jobs negotiated a visit to see the Xerox Alto computer and Smalltalk development tools in exchange for Apple stock options. The final Lisa and Macintosh operating systems mostly used concepts from the Xerox Alto, but many elements of the graphical user interface were created by Apple including the menubar and pop-up menus.



    Unlike the IBM PC, which used 8 kB of system ROM for power-on self-test (POST) and basic input/output system (BIOS), the Mac ROM was significantly larger (64 kB) and held key OS code. Much of the original Mac ROM was coded by Andy Hertzfeld, a member of the original Macintosh team. He was able to conserve some of the precious ROM space by interleaving some of the assembly language code. In addition to coding the ROM, he also coded the kernel, the Macintosh Toolbox and some of the desktop accessories (DAs) as well. The icons of the operating system, which represented folders and application software were designed by Susan Kare, who later designed the icons for Microsoft Windows 3.0. Bruce Horn and Steve Capps wrote the Macintosh Finder as well as a number of Macintosh system utilities.




    Apple was very strong in advertising their newfound machine. After it was created, the company bought all 39 pages of advertisement space in the Newsweek magazine, 1984 November/December edition. Apple was so successful in its marketing for the Macintosh, that it quickly outshone its more sophisticated predecessor, the Lisa, in sales – so much so that Apple quickly developed a product called MacWorks which allowed the Lisa to emulate Macintosh system software through System 3, by which time it had been discontinued as the re-branded Macintosh XL. Many of Lisa's operating system advances would not appear in the Macintosh OS until System 7.

History Of Linux

LINUX's History

Note: The following text was written by Linus on July 31 1992. It is a
   collection of various artifacts from the period in which Linux first
   began to take shape.
  
   This is just a sentimental journey into some of the first posts
   concerning linux, so you can happily press 'n' now if you actually
   thought you'd get anything technical.
From: torvalds@klaava.Helsinki.FI (Linus Benedict Torvalds)
  Newsgroups: comp.os.minix
  Subject: Gcc-1.40 and a posix-question
  Message-ID:
  Date: 3 Jul 91 10:00:50 GMT

  Hello netlanders,

  Due to a project I'm working on (in minix), I'm interested in the posix
  standard definition. Could somebody please point me to a (preferably)
  machine-readable format of the latest posix rules? Ftp-sites would be
  nice.

   The project was obviously linux, so by July 3rd I had started to think
   about actual user-level things: some of the device drivers were ready,
   and the harddisk actually worked. Not too much else.





  As an aside for all using gcc on minix - [ deleted ]

   Just a success-report on porting gcc-1.40 to minix using the 1.37
   version made by Alan W Black & co.

  PS. Could someone please try to finger me from overseas, as I've
  installed a "changing .plan" (made by your's truly), and I'm not certain
  it works from outside? It should report a new .plan every time.

History of Electricity



 History of Electricity


Starting With Mr. Edison and
Ben Franklin His Light
Many people think Benjamin In 1879, Thomas Edison
Franklin discovered electricity focused on inventing a
with his famous kite-flying practical light bulb, one that
experiments in 1752, but would last a long time before
electricity was not discovered burning out. The problem was
all at once. At first, electricity finding a strong material for
was associated with light. the filament, the small wire
People wanted a cheap inside the bulb that conducts
and safe way to light their electricity. Finally, Edison used
homes, and scientists thought ordinary cotton thread that
electricity might be a way. had been soaked in carbon.
                           This filament didn’t burn at
                            all—it became incandescent;
                             that is, it glowed.

The Battery
Learning how to produce
and use electricity was not
easy. For a long time there
was no dependable source
of electricity for experiments.
Finally, in 1800, Alessandro
Volta, an Italian scientist, made
a great discovery. He soaked
paper in salt water, placed zinc
and copper on opposite sides
of the paper, and watched the
chemical reaction produce
an electric current. Volta had
created the first electric cell.
By connecting many of these Alessandro Volta
cells together, Volta was able
to “string a current” and create
a battery. It is in honor of Volta that we measure battery power
in volts. Finally, a safe and dependable source of electricity was
available, making it easy for scientists to study electricity.

A Current Began
An English scientist, Michael Faraday, was the first one to realize that
an electric current could be produced by passing a magnet through
a copper wire. It was an amazing discovery. Almost all the electricity
we use today is made with magnets and coils of copper wire in giant
power plants.
Both the electric generator and electric motor are based on this
principle. A generator converts motion energy into electricity. A
motor converts electrical energy into motion energy.

Thomas Edison in his lab in 1901.
The next challenge was developing an electrical system that could
provide people with a practical source of energy to power these new
lights. Edison wanted a way to make electricity both practical and
inexpensive. He designed and built the first electric power plant that
was able to produce electricity and carry it to people’s homes.
Edison’s Pearl Street Power Station started up its generator on
September 4, 1882, in New York City. About 85 customers in lower
Manhattan received enough power to light 5,000 lamps. His
customers paid a lot for their electricity, though. In today’s dollars,
the electricity cost $5.00 per kilowatt-hour! Today, electricity costs
about 12 cents per kilowatt-hour for residential customers, and
about 7 cents per kilowatt-hour for industry.
