Charles Babbage Biography

Charles Babbage was born in London Dec. 26, 1791, St. Stephan day, in London. He was son of Benjamin Babbage, a banking partner of the Praeds who owned the Bitton Estate in Teignmouth and Betsy Plumleigh Babbage. It was about 1808 when the Babbage family decided to move into the old Rowdens house, located in East Teignmouth, and Benjamin Babbage became a warden of the nearby church of St. Michael.

The father of Charles was a rich man, so it was possible for Charles to receive instruction from several elite schools and teachers during the course of his elementary education. He was about eight when he had to move to a country school to recover from a dangerous fever. His parents sentenced that his "brain was not to be taxed too much"; Babbage wrote: "this great idleness may have led to some of my childish reasonings."
Then, he joined King Edward VI Grammar School in Totnes, South Devon, a thriving comprehensive school that's still operative today, but his fragile health status forced him back to private teaching for a period. Then, he finally joined a 30-student closed number academy managed by Reverend Stephen Freeman. The academy had a big library, where Babbage used to study mathematics by himself, and learned to love it. He had two more personal tutors after leaving the academy. One was a clergyman of Cambridge, and about him Babbage said: "I fear I did not derive from it all the advantages that I might have done.". The other one was an Oxford tutor who teached Babbage the Classics, so that he could be accepted to Cambridge.

Babbage arrived at Trinity College, Cambridge in October 1810. He had a big culture - he knew Lagrange, Leibniz, Lacroix, Simpson... and he was seriously disappointed about the math programs available at Cambridge. So he, with J.Herschel, G.Peacock, and other friends, decided to form the Analytical Society.

When, in 1812, Babbage transferred to Peterhouse, Cambridge, he was the best mathematician; but he failed to graduate with honours.
He received an honorary degree later, without even being examinated, in 1814.

In 1814, Charles Babbage married Georgiana Whitmore at St. Michael's Church in Teignmouth, Devon. His father, for some reason, never gave his approvation. They lived in tranquility at 5 Devonshire Street, Portland Place, London.
Only Three of their 8 children became adult.
Tragically, Charles' father, his wife and one of his sons all died in 1827.

A Brief History Of Computer Virus

There is a great deal of debate about this history and evolution of computer viruses. Although many experts may disagree on the origins of viruses, their history is an interesting one. Computer viruses have evolved over the years as the measures taken to detect and disable viruses have become more effective. There is a constant struggle between programmers who write viruses and the programmers who create anti-Virus Software, with one group trying to stay a step ahead of the other. Computer users can more effectively defend themselves against viruses when they have an understanding of how viruses work and their origins.

In 1949, a mathematician named John Von Neumann introduced the concept of programs that could be taught to replicate themselves. Although this thinking was way ahead of its time, the roots of computer viruses can be traced to the principles Von Neumann was describing. Nearly 20 years later, in the late 1960s, computer users created a game called “Core Wars,” where they would attempt to occupy all of the existing memory on other player’s computers. Programmers at the time had no idea that they were writing computer viruses.

The first known personal computer virus was called the brain virus, and it began infecting PCs in 1986. The Brain Virus was created in Pakistan and was a boot sector virus that affected disk space as opposed to hard drives. The virus would render floppy disks unusable by eliminating their available space. The Brain Virus was a “Stealth” virus, or in other words a virus that tried to affect machines without being noticed by the user. The first anti-virus program was created in 1988. The program was designed specifically to deal with the Brain Virus, detecting, removing, and protecting disks from future problems with the virus. The first Trojan horse virus was also created in the mid 1980′s.

In late 1987, the first “memory resident file infector” was createdóa virus that was embedded in a file and attacked only once the program was ordered to execute by the user. The first of these viruses was called the Lehigh Virus, as the first computers it attacked were at Lehigh University. A month later, a similar virus, called the Jerusalem Virus, attacked in Israel, becoming the first virus that replicated itself within infected files.

In 1990, several companies started selling anti-virus software, including IBM and McAfee, with Symantec introducing Norton Anti-Virus software in 1991. Viruses were become more stealth and more effective than ever before and the need for anti-virus software was growing for PC owners. Ironically, only a few years later, most computer experts felt that anti-virus software would no longer be necessary once Microsoft released its 1995 version of Windows, a fact that is hard to believe in retrospect.

Nearly every year since the mid 90′s, another new virus has been created, detected, and rendered ineffective by anti-virus software. The tug of war between programmers who write viruses and anti-virus software programmers will likely continue for years to come.

Bill Gates Biography


Bill Gates Biography (William Henry Gates III): Microsoft Founder
Famous for : Being the richest man in the world, a cofounder of the software company Microsoft, and for being one of the world's most generous philanthropists.
Gates details : Born - USA October 28, 1955 Lives - United States of America

Bill Gates is one of the most influential people in the world. He is cofounder of one of the most recognized brands in the computer industry with nearly every desk top computer using at least one software program from Microsoft. According to the Forbes magazine, Bill Gates is the richest man in the world and has held the number one position for many years.

Gates was born and grew up in Seattle, Washington USA. His father, William H. Gates II was a Seattle attorney and his mother, Mary Maxwell Gates was a school teacher and chairperson of the United Way charity. Gates and his two sisters had a comfortable upbringing, with Gates being able to attend the exclusive secondary "Lakeside School".

Bill Gates started studying at Harvard University in 1973 where he spent time with Paul Allen. Gates and Allen worked on a version of the programming language BASIC, that was the basis for the MITS Altair (the first microcomputer available). He did not go on to graduate from Harvard University as he left in his junior year to start what was to become the largest computer software company in the world; Microsoft Corporation.

Bill Gates and the Microsoft Corporation
"To enable people and businesses throughout the world to realize their full potential." Microsoft Mission Statement
After dropping out of Harvard Bill Gates and his partner Paul Allen set about revolutionizing the computer industry. Gates believed there should be a computer on every office desk and in every home.

In 1975 the company Micro-soft was formed, which was an abbreviation of microcomputer software. It soon became simply "Microsoft"® and went on to completely change the way people use computers.

Microsoft helped to make the computer easier to use with its developed and purchased software, and made it a commercial success. The success of Microsoft began with the MS-DOS computer operating system that Gates licensed to IBM. Gates also set about protecting the royalties that he could acquire from computer software by aggressively fighting against all forms of software piracy, effectively creating the retail software market that now exists today. This move was quite controversial at the time as it was the freedom of sharing that produced much innovation and advances in the newly forming software industry. But it was this stand against software piracy, that was to be central in the great commercial success that Microsoft went on to achieve.

Bill Gates retired as Microsoft CEO in 2008.

Bill Gates Criticism
With his great success in the computer software industry also came many criticisms. With his ambitious and aggressive business philosophy, Gates or his Microsoft lawyers have been in and out of courtrooms fighting legal battles almost since Microsoft began.

The Microsoft monopoly sets about completely dominating every market it enters through either acquisition, aggressive business tactics or a combination of them. Many of the largest technology companies have fought legally against the actions of Microsoft, including Apple Computer, Netscape, Opera, WordPerfect, and sun Microsystems.

Bill Gates Net Worth

With an estimated wealth of $53 billion in 2006, Bill Gates is the richest man in the world and he should be starting to get used to the number spot as he has been there from the mid-ninties up until now. The famous investor Warren Buffett is gaining on Gates though with an estimated $46 billion in 2006.

Microsoft hasn't just made Bill Gates very wealthy though. According to the Forbes business magazine in 2004 Paul Allen, Microsoft cofounder was the 5th richest man in the world with an estimated $21 billion. While Bill Gates' long time friend and Microsoft CEO, Steve Ballmer was the 19th richest man in the world at $12.4 billion.


Bill Gates Philanthropy
Being the richest man in the world has also enabled Gates to create one of the world's largest charitable foundations. The Bill and Melinda Gates Foundation has an endowment of more than $28 billion, with donations totaling more than $1 billion every year. The foundation was formed in 2000 after merging the "Gates Learning Foundation" and "William H. Gates Foundation". Their aim is to "bring innovations in health and learning to the global community".

Bill Gates continues to play a very active role in the workings of the Microsoft Company, but has handed the position of CEO over to Steve Ballmer. Gates now holds the positions of "Chairman" and "Chief Software Architect". He has started that he plans to take on fewer responsibilities at Microsoft and will eventually devote all his time to the Bill & Melinda Gates Foundation.

In 2006, the second richest man in the world, Warren Buffett pledged to give much of his vast fortune to the Bill and Melinda Gates Foundation.

Bill Gates Receives a KBE
In March 2005 William H. Gates received an "honorary" knighthood from the queen of England. Gates was bestowed with the KBE Order (Knight Commander of the Most Excellent Order of the British Empire) for his services in reducing poverty and improving health in the developing countries of the world.
After the privately held ceremony in Buckingham Palace with Her Majesty Queen Elizabeth II, Gates commented on the recognition..
"I am humbled and delighted. I am particularly pleased that this honor helps recognize the real heroes our foundation (Bill and Melinda Gates Foundation) supports to improve health in poor countries. Their incredible work is helping ensure that one day all people, no matter where they are born, will have the same opportunity for a healthy life, and I'm grateful to share this honor with them."

The KBE Order of the British Empire is the second highest Order given out, but it is only an honorary knighthood as only citizens that are British or a part of the Commonwealth receive the full Order. This means that Gates does not become Sir Bill Gates.

Bill Gates lives near Lake Washington with his wife Melinda French Gates and their three children. Interests of Gates include reading, golf and playing bridge.
