Software bugs
A probe launched from Cape Canaveral was set to go to Venus. After takeoff, the unmanned rocket carrying the probe went off course, and NASA had to blow up the rocket to avoid endangering lives on earth. NASA later attributed the error to a faulty line of FORTRAN code. The report stated, "Somehow a hyphen had been dropped from the guidance program loaded aboard the computer, allowing the flawed signals to command the rocket to veer left and nose down... Suffice it to say, the first U.S. attempt at interplanetary flight failed for want of a hyphen." The vehicle cost more than $80 million, prompting Arthur C.Clarke to refer to the mission as "the most expensive hyphen in history."
9. Radiation machine kills four: 1985 to 1987
Faulty software in a Therac-25 radiation-treatment machine made by Atomic Energy of Canada Limited (AECL) resulted in several cancer patients receiving lethal overdoses of radiation. Four patients died. When their families sued, all the cases were settled out of court. A later investigation by independent scientists Nancy Leveson and Clark Turner found that accidents occurred even after AECL thought it had fixed particular bugs. "A lesson to be learned from the Therac-25 story is that focusing on particular software bugs is not the way to make a safe system," they wrote in their report." The basic mistakes here involved poor software-engineering practices and building a machine that relies on the software for safe operation."
8. AT&T long distance service fails: 1990
Switching errors in AT&T's call-handling computers caused the company's long-distance network to go down for nine hours, the worst of several telephone outages in the history of the system. The meltdown affected thousands of services and was eventually traced to a single faulty line of code.
7. Patriot missile misses: 1991
The U.S. Patriot missile's battery successfully headed off many Iraqi Scuds during the Gulf War. But the system also failed to track several incoming Scud missiles, including one that killed 28 U.S. soldiers in a barracks in Dhahran, Saudi Arabia. The problem stemmed from a software error that put the tracking system off by 0.34 of a second. As Ivars Peterson states in Fatal Defect, the system was originally supposed to be operated for only 14 hours at a time. In the Dhahran attack, the missile battery had been on for 100 hours. This meant that the errors in the system's clock accumulated to the point that the tracking system no longer functioned. The military had in fact already found the problem but hadn't sent the fix in time to prevent the barracks explosion.
6. Pentium chip fails math test: 1994
The concept of bugs entered the mainstream when Professor Thomas Nicely at Lynchburg College in Virginia discovered that the Pentium chip gave incorrect answers to certain complex equations. In fact, the bug occurred rarely and affected only a tiny percentage of Intel's customers. The real problem was the nonchalant way Intel reacted. "Because we had been marketing the Pentium brand heavily, there was a bigger brand awareness," says Richard Dracott, Intel director of marketing. "We didn't realize how many people would know about it, and some people were outraged when we said it was no big deal." Intel eventually offered to replace the affected chips, which Dracott says cost the company $450 million. To prove that it had learned from its mistake, Intel then started publishing a list of known "errata," or bugs, for all of its chips.
5. Intuit's MacInTax leaks financial secrets: 1995
Intuit's tax software for Windows and Macintosh has suffered a series of bugs, including several that prompted the company to pledge to pay any resulting penalties and interest. The scariest bug was discovered in March 1995: the code included in a MacInTax debug file allowed UNIX users to log in to Intuit's master computer, where all MacInTax returns were stored. From there, the user could modify or delete returns. Intuit later ended up winning BugNet's annual bug-fix award in 1996 by responding to bugs faster than any other major vendor.
4. New Denver airport misses its opening: 1995
The Denver International Airport was intended to be a state-of-the-art airport, with a complex, computerized baggage-handling system and 5,300 miles of fiber-optic cabling. Unfortunately, bugs in the baggage system caused suitcases to be chewed up and drove automated baggage carts into walls. The airport eventually opened 16 months late, $3.2 billion over budget, and with a mainly manual baggage system.
3. Java opens security holes; browsers simply crash: 1996 to 1997
All right, this is not a single bug but a veritable bug collection. We include this entry because the sheer quantity of press coverage about bugs in Sun's Java and the two major browsers has had a profound affect on how the average consumer perceives the Internet. The conglomeration of headlines probably set back the e-commerce industry by five years. Java's problems surfaced in 1996, when research at the University of Washington and Princeton began to uncover a series of security holes in Java that could, theoretically, allow hackers to download personal information from someone's home PC. To date, no one has reported a real case of a hacker exploiting the flaw, but knowing that the possibility existed prompted several companies to instruct employees to disable Java in their browsers. Meanwhile, Netscape and Microsoft began battling in earnest in the much-publicized browser wars. That competition inspired both companies to accelerate the schedules for their 4.0 releases, and the result has been a swarm of bugs, ranging from JavaScript flaws in Netscape's Communicator to a reboot bug in Microsoft's Internet Explorer. Communicator is now in Version 4.04 for Windows 95 and Windows NT, six months after its first release. Internet Explorer 4.01, the first of presumably many bug-fix versions, arrived in December, two months after the initial release of IE 4.0.
2. Deregulation of California utilities has to wait: 1998
Two new electrical power agencies charged with deregulating the California power industry have postponed their plans by at least three months. The delay will let them debug the software that runs the new power grid. Consumers and businesses were supposed to be able to choose from some 200 power suppliers as of January 1, 1998, but time ran out for properly testing the communications system that links the two new agencies with the power companies. The project was postponed after a seven-day simulation of the new system revealed serious problems. The delay may cost as much as $90 million--much of which may eventually be footed by ratepayers, and which may cause some of the new power suppliers to go into debt or out of business before they even start.
1. The millennium bug: 2000
For a long time, programmers have saved memory space by leaving only two numeric fields for the year instead of four: 87 instead of 1987, for example. When clocks strike midnight on January 1, 2000, this programming shorthand will make millions of computers worldwide think it's 1900, if their software isn't fixed before then. The so-called year 2000 (Y2K) bug has given birth to a cottage industry of consultants and programming tools dedicated to making sure the modern world doesn't come to a screeching halt on the first day of the next century. Some say that the bug will cause airplanes to fall from the sky, ATMs to shut down, and Social Security checks to bounce. At the very least, the bug is a huge and expensive logistical problem, although most vital organizations now say they will have fixed the critical portions of their systems in time.
Finally, it all turned into a damp squid. There was no "calamities" reported as the clock ticked past midnight on the 31st of Dec, 1999

Inspiring Stories
In 1962, four nervous young musicians played their first record Audition for the executives of the Decca Recording Company. The executives were not impressed. While turning down this group of musicians, one executive said,"We don't like their sound. Groups of guitars are on the way out." The group was called The Beatles.
In 1944, Emmeline Snively, director of the Blue Book Modelling Agency, told modelling hopeful Norma Jean Baker, "You'd better learn secretarial work or else get married." She went on and became Marilyn Monroe.
In 1954, Jimmy Denny, manager of the Grand Ole Opry, fired a singer after one performance. He told him, "You ain't goin' nowhere....son. You ought to go back to drivin' a truck." He went on to become the most popular singer in America named Elvis Presley.
When Alexander Graham Bell invented the telephone in 1876, it did not Ring off the hook with calls from potential backers. After making a demonstration call, President Rutherford Hayes said, "that's an amazing invention, but who would ever want to use one of them?"
When Thomas Edison invented the light bulb, he tried over 2000 Experiments before he got it to work. A young reporter asked him how it felt to fail so many times. He said, "I never failed once. I invented the light bulb. It just happened to be a 2000-step process."
In the 1940s, another young inventor named Chester Carlson took his idea to 20 corporations, including some of the biggest in the country. They all turned him down. In 1947 - after seven long years of rejections, he finally got a tiny company in Rochester, New York, the Haloid company, to purchase the rights to his invention an electrostatic paper-copying process. Haloid became Xerox Corporation we know today.
Wilma Rudolph was the 20th of 22 children. She was born prematurely and her survival was doubtful. When she was 4 years old, she contacted double pneumonia and scarlet fever, which left her with a paralysed left leg. At age 9, she removed the metal leg brace she had been dependent on and began to walk without it. By 13 she had developed a rythmic walk, which doctors said was a miracle. That same year she decided to become a runner. She entered a race and came in last. For the next few years every race she entered, she came in last. Everyone told her to quit, but she kept on running. One day she actually won a race. And then another. From then on she won every race she entered. Eventually this little girl, who was told she would never walk again, went on to win three Olympic gold medals and was declared the fastest woman in the world in 1960.
The above stories are inspiring and should make you introspect, experiment, try out many things and find out what you really like and enjoy doing. Experiment still further and that will take you on the road to excellence in whatever you enjoy doing. That becomes your identity and your character which only develops from your own persistence, through experience of trial and sometimes suffering, the character is strengthened, vision is cleared, ambition is inspired and success is achieved. Learn to look at fear and failure in the face and accept challenges to attempt to do the things that seems insurmountable.
A winner is not one who never fails, but one who never quits!

Jokingly
The word "politics" is derived from the word "poly", meaning "many", and the
word "ticks", meaning "blood sucking parasites."
The celebrants were impressed with the centenarian's agility and good health, and asked how he managed to keep up his rigorous fitness regime.
“Gentlemen, I will tell you the secret of my success,” he cackled. “I have been in the open air day after day for some 75 years now.”
“Well, you see my wife and I were married 75 years ago. On our wedding night, we made a solemn pledge. Whenever we had a fight, the one who was proved wrong would go outside and take a walk.”
Two attorneys went into a diner and ordered two drinks. Then they produced sandwiches from their briefcases and started to eat.
The owner became quite concerned and marched over and told them, "You can't eat your own sandwiches in here!"
The attorneys looked at each other, shrugged their shoulders and then exchanged sandwiches.
"So let me get this straight," the prosecutor says to the defendant, "you came home from work early and found your wife in bed with a strange man."
"That's correct," says the defendant.
"Upon which," continues the prosecutor, "you take out a pistol and shoot your wife, killing her."
"That's correct," says the defendant.
"Then my question to you is, why did you shoot your wife and not her lover?" asked the prosecutor.
"It seemed easier," replied the defendant, "than shooting a different man every day!"
There was this virgin that was going out on a date for the first time and she told her grandmother about it. So, the grandmother says sit here and let me tell you about those young boys.
He is going to try to kiss you, you are going to like that but, don't let him do that. He is going to try to feel your breast, you are going to like that but, don't let him do that.
He is going to try to put his hand between your legs, you are going to like that but, don't let him do that.
But most important, he is going to try to get on top of you and have his way with you. You are going to like that but, don't let him do that, it will disgrace the family.
With that bit of advise, the granddaughter went on her date and could not wait to tell her grandmother about it.
So, the next day she told her grandmother that her date went just like she had said. But, she said, “grandmother, I didn't let him disgrace the family”. When he tried that I turned him over, got on top of him and disgraced his family.
The secretary came in late for work the third day in a row. The boss called her into his office and said, “Now look Sharon, I know we had a wild fling for a while, but that’s over. I expect you to conduct yourself like any other employee around here. Who told you, you could come and go as you please around here?”
Sharon simply smiled, lit up a cigarette, and while exhaling said, “My lawyer.”
“Ever since we got married, my wife has tried to change me. She got me to stop drinking, smoking and running around until all hours of the night. She taught me how to dress well, enjoy the fine arts, gourmet cooking, classical music, even how to invest in the stock market.”
“Sounds like you may be bitter because she changed you so drastically,” remarked his friend.
“I’m not bitter. Now that I’m so improved, she just isn’t good enough for me.”

Freedom of thought
The Internet was created by a few visionaries, who wanted a world of free thought and expression, ideas, dreams and vision, a world beyond boundaries - a freedom of a different dimension, away from all controls, and unrestricted by the world governed by the political kind. It was a wonderful dream. Sadly, the creators of the internet envisaged only in the goodness of men and they were proved wrong. So, as the internet spread into new horizons as it was meant to, the dream did not last very long.
The first assault on that was the world of commerce and consumerism. Along with it came the crackers and other lunatics and logically followed by the "undesired" government controls. There were protests, loud and clear - but, it was only from a few, so it was drowned in the, cacophony of coloured dangers and good intentions.
However, that did not stifle or stop the power and reach of internet as it was an open ended idea - only limited by mans imagination. Internet took everything in it's stride - growing as a platform and integrating every new idea and invention into and within it.
Every day, as the internet connectivity took new strides and advanced, it gave more power, more information and far more reach to the individual. Many good people used this vehicle to create a better world for themselves and humanity in general. The same tool in others' hands were used for nefarious purposes - to satiate their greed and lust or their personal or collective agendas. This called for more laws and more controls by the government. By now the stifled protests remained just that. In fact, as some groups started terrorising the world people started voluntarily surrendering their liberties to their government - because, "liberty" in a sense has been lost for ever!
Today, governments are dictating how internet will be used. They are perforce invited to stifle it in order to protect themselves from that one invisible enemy at a tremendous cost to the personal liberties and the freedom envisaged by their creators. While Blackberry is being forced by the Indian government to reveal their codes of their intellectual properties, the US is mulling over laws to force design changes in software for emails, other normally used voice communication tools and social networking sites.
Yet, internet will grow. Most men will use it to realise their dreams - mostly good. Few will thwart and misuse it for their evil designs. We can only hope the evil will stop. If it doesn't, there will come a day when you can never be sure the email that you sent will reach their intended destination or not at all.
Then, we can switch to snail mail?
A manifestation of that freedom is enjoyed by Priya today in Spain, as expressed in her post :
"Day 11,12,13 - Valdelavilla: a tiny tiny Spanish village. The sun shines differently here, everything is golden, everything is warm. Something changed inside me. I´m discovering who I am as I´m talking to the Spaniards about myself. I came here to teach them English but instead I´m the one learning about life."
Thought of adding some quotes related to freedom, that come to mind in the current environment :
There may be times when we are powerless to prevent injustice, but there must never be a time when we fail to protest. - Elie Wiesel (A holocaust survivor)
When the Nazis came for the communists,
I remained silent;
I was not a communist.
When they locked up the social democrats,
I remained silent;
I was not a social democrat.
When they came for the trade unionists,
I did not speak out,
I was not a trade unionists.
When they came for the Jews,
I remained silent,
I was not a Jew.
When they came for me,
There was no one left to speak out.
- Martin Niemoller

We must not permit our respect for the dead or our sympathy for the living to lead us into an act of injustice to the balance of the living. - Davy Crockett
True patriotism hates injustice in its own land more than anywhere else. - Clarence Darrow
There is no flag large enough to cover the shame of killing innocent people. - Howard Zinn
There is no calamity which a great nation can invite which equals that which follows a supine submission to wrong and injustice and the consequent loss of national self-respect and honor, beneath which are shielded and defended a people's safety and greatness. - Eldridge Cleaver

Change you desire
The progress India has made in the last two decades have been exemplary. Much of this has been foreseen by experts based on the trends in the late eighties. The forecast and the achievement has been basically driven the private sector, and they have certainly delivered. This has given us a lot of financial clout in the international arena. Needless to say, in the present state, when an Indian acquires some financial clout it is but natural that the muscles twitch. So, we have seen, in the recent past, true to our culture, there has been instances where India has not shied away from flexing it's financial muscle, much to the exasperation of few other countries!
Still, there are areas where a lot remain to be done. None of those economic benefits have reached a third of our population - which is living in abject poverty. Our infrastructure is dismally third world. We have problems of very serious nature in half the number of states of our country. A third of our country is more or less, beyond the governance of our polity. Worse, corruption and apathy at all levels is visible clearly in every facet of our life and governance.
Very good suggestions have been given by many great people on how to remedy the situation. In fact, most people agree that few of these suggestions, if implemented, can get us on the road to greatness as a nation, in a very short time. Yet, nothing is done. Things are getting worse every day. We have the financial resources to do many things - but the fruits of that is not enjoyed by the average citizen least of all, the poor, who actually need it badly.
Development is not all about becoming a financial superpower. It also should ensure the spiritual development of the individual and community. Education and literacy is one part of it. The moral and ethical development is the other essential. Though we boast about our "age old culture" no one will dispute that it has either seen a lot of erosion, or more realistically it never existed. We can not fault anyone for making such a comment today, if we go around observing the news and events round the country.
"If you want to civilize a man, you have to start from the grandmother" - is a very common quote. We are in somewhat of a similar situation. The remedy has not yet started, but this generation has the responsibility to take the "grandmother's" station, so that it can help the future generation to attain some degree of moral and ethical civility. When I see some kids of today, it appears their parents have been very successful in keeping that "good part of our ancient culture" well hidden from their children. Maybe, in the mad rush for gold they did not have the time, or the inclination to inculcate those qualities - or, they realized that these qualities are only a hindrance in this race for the pot of gold.
Whatever the reason, if you need to brush up on some things that need to be done to see future generations in a better position - a small article by Chetan Bhagat in today's Times of India, will help everyone. It is a very simple and well written article - and will not give you a headache. In fact, you may well enjoy reading it. I would go so far as to suggest that everyone educated in English should read it, and if possible - translate it into their own language and essentially into thier lifestyle!
