Just came across an old mail from God aka Bjarne Stroustrup. I was ecstatic when I received a mail from him as I never expected a reply for such a naive query. Below is the mail

Don't delete a pointer twice.
I don't see any alternative to tracking down that bug. It is serious and
could easily be the indicator of some serious problems with resource
management. Try using a leak detector; sometimes they can catch double
deletions.

There is a way to be good again
Past 3 days were very emotional for me as
1. I was reading "Kite Runner" by Khalid Hosseini.
2. Yet another BAD appraisal.
I am used to such appraisal's hence I stopped worrying about. But I am still worrying about Hasan and Amir, on whom the "Kite Runner" is based. Phew what a book, it's one of those rare books that touches your soul and leaves a long lasting imprint on your mind. It's an emotional story of two friends (Amir and Hasan) based in Afghanistan, they grow up together and later due to some circumstances their lives takes different path. There is war on Afghanistan and Amir settles in America while Hasan stays in Afghanistan. During their childhood days Amir did some mistakes because of which Hasan suffers, but later he gets a way to be good again. Thus the central theme of this book "There is a way to be good again".
PS: Yesterday a friend of mine Rohit told me that he can't write comments on my blog as I blocked anonymous people for writing comments. I was really glad that some people are reading my blog. I will remove the restrictions and please do write your valuable comments.
Quotes on programmers
A good programmer is someone who always looks both ways before crossing a one-way street. ~Doug Linder
If debugging is the process of removing bugs, then programming must be the process of putting them in. ~Author Unknown
Everyone knows that debugging is twice as hard as writing a program in the first place. So if you are as clever as you can be when you write it, how will you ever debug it? ~Brian Kernighan
Always code as if the guy who ends up maintaining your code will be a violent psychopath who knows where you live. ~Martin Golding
Any fool can write code that a computer can understand. Good programmers write code that humans can understand. ~Martin Fowler
Beta. Software undergoes beta testing shortly before it’s released. Beta is Latin for “still doesn’t work.” ~Author Unknown
Controlling complexity is the essence of computer programming. ~Brian Kernighan
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?” ~Steve McConnell
Programming is similar to a game of golf. The point is not getting the ball in the hole but how many strokes it takes. ~Harlan Mills
When debugging, novices insert corrective code; experts remove defective code. ~Richard Pattis
