Gr8 s/w quotes
–Dennis Ritchie
Before software can be reusable, it first has to be usable.
–Ralph Johnson
Good judgment comes from experience, and experience comes from bad judgment.
–Fred Brooks
Theory is when you know something, but it doesn’t work. Practice is when something works, but you don’t know why it works. Programmers combine theory and practice: Nothing works and they don’t know why.
It’s hard enough to find an error in your code when you’re looking for it; it’s even harder when you’ve assumed your code is error-free.
-Steve McConnell Code Complete
If builders built buildings the way programmers wrote programs, then the first woodpecker that came along would destroy civilisation.

Enthusiasm
Disillusionment
Panic
Search for the Guilty
Punishment of the Innocent
Praise for non-participants
Good code is its own best documentation. As you’re about to add a comment, ask yourself, ‘How can I improve the code so that this comment isn’t needed?’ Improve the code and then document it to make it even clearer.
–Steve McConnell Code Complete
The trouble with the world is that the stupid are cocksure and the intelligent are full of doubt.
–Bertrand Russell
No matter how slick (efficient) the demo is in rehearsal, when you do it in front of a live audience the probability of a flawless presentation is inversely proportional to the number of people watching, raised to the power of the amount of money involved.
One of the main causes of the fall of the Roman Empire was that, lacking zero, they had no way to indicate successful termination of their C programs.
–Robert Firth
Fifty years of programming language research and we end up with C++?
–Richard A. O’Keefe
C programmers never die. They are just cast into void.
If debugging is the process of removing bugs, then programming must be the process of putting them in.
–Edser Dijkstra
You can either have software quality or you can have pointer arithmetic, but you cannot have both at the same time.
–(Bertrand Meyer)
There are two ways to write error-free programs; only the third works.
–Alan J. Perlis
Measuring programming progress by lines of code is like measuring aircraft building progress by weight.
–Bill Gates
The first 90% of the code accounts for the first 90% of the development time. The remaining 10% of the code accounts for the other 90% of the development time.
–Tom Cargill
Programmers are in a race with the Universe to create bigger and better idiot-proof programs, while the Universe is trying to create bigger and better idiots. So far the Universe is winning.
–Anon
As soon as we started programming, we found to our surprise that it wasn’t as easy to get programs right as we had thought. Debugging had to be discovered. I can remember the exact instant when I realized that a large part of my life from then on was going to be spent in finding mistakes in my own programs.
–Maurice Wilkes discovers debugging, 1949
I did say something along the lines of “C makes it easy to shoot yourself in the foot; C++ makes it harder, but when you do, it blows your whole leg off.”

The age of 'blog ' pathys
The age of 'blog ' pathys
Frustrated with the fact that the money making drill known as your job has evolved into sitting at a desk from 9 to 5, getting paid peanuts at the end of the month? For all those buckling under the monotony of daily life, the global phenomenon called blogging may just have opened the doors to wealth heretofore unseen in office space.
But how does this work? The answer lies in the revenue generated from ads posted on each blogger’s site. Kiruba Shankar, a popular blogger from Chennai, says, “There are several ways to make a handsome earning through blogs. However, the most popular mode happens to be through ads, specifically – Google’s Adsense service. Subscribers of the service are paid a commission on the basis of the number of hits that ads placed on the subscribers’ blog get. The ads are posted according to the relevance of the blog.”
If you are a lover of gadgets and you frequently blog about the latest in gizmos, your blog could be posted with ads pertaining to local dealers of such gadgets, auctioning sites that sell them at different rates etc. The revenue earned by a blogger would depend on various factors. Ganesh, the blogmeister of Rupaiya.com explains this, “The money you make from the ads depends on the subject of the blog, it’s popularity and its ranking. For an ad space, one can earn anywhere between Rs. 2,000 to Rs. 9,000 per month. Hits on these advertisements could a fetch a blogger anywhere between Rs 4 to Rs. 300.” Ganesh says, “I have made about Rs 7 lakh in about a year and a half. But there are even those who earn from Rs 5 lakh to Rs 20 lakh per month.”
Parminder Singh, the business head of technology, Google India says, “The revenue as well as the exact number of bloggers in Adsense are confidential. Of course, it’s very popular in India and almost every major blogger is a part of it.”
However, ads are not the only way to make money through blogs. Ramanujam, an engineering graduate who makes more money from his blogs than his ads says, “I write product reviews and link my blog to the product’s website. So in turn, that company pays me.” He adds, “I have made almost a six-figure amount which is enough to sponsor my higher education.” But before these figures tempt you to quit your job and start blogging, Kiruba cautions, “It may look like the next big thing in terms of money, but it’s not as easy as it seems. Only a fraction make that kind of money. Moreover it takes a blogger almost a year, maybe more to make money.” Jamshed. V. Rajan, the product head of Ibibo.com, says, “Even though some portals have a system similar to Google’s, they are not as popular, due to the factors like accuracy, relevance etc.”
