Wife : Why do you always criticize my parents?
Husband : I have so much anger. To reduce it, I have to show that on someone. So, I am showing it on your parents.
Wife : In that case, I also have so much anger. On whom should I show it?
Husband : Show it on whomever you like.
Wife : I like you.

I Hate GPL
Those whoever worked with me for quite some time, will be definitely surprized by this heading. Yes. I hate GPL. The only two open source licenses, that I don't like among OSI (Open source initiative) approved licenses are GPL and CDDL license. I don't like CDDL, and I hate GPL. But, I love LGPL.
CDDL: I don't know why this is an OSI approved license. With this license, I cannot change the code and give it to my friend. What freedom do we get by this license?
For those who do not know about GPL and LGPL licenses,
GPL: You will get source code, you can modify it, and you can distribute it for free. If you modify it, or use this code in some other application, the modified code, and the new application also would be under GPL. Those whoever gets it, they get whatever rights you got.
LGPL: It is similar to GPL, but, if you are using this code in different application as a library, then the entire application need NOT be released as LGPL, but, only the library has to be released under LGPL.
For those who cannot understand the minute details of these licenses, they may think both are almost same. But, they are like North and South.
Let's take an example.
The most popular logger for java is log4j. If this has been released under GPL, nobody would have used this library. Because, if anybody uses the log4j library in their application, they have to release the entire application as GPL. So, NO COMPANY will use log4j in their application. But, on the other hand, if it is released under LGPL, then everyone would use it. Because, for LGPL, we have to release only that library under LGPL. We can release the entire application with whatever license we want. (Of course, log4j is released under Apache Software License, the most flexible license, you can modify the code, and sell it for money without granting any permissions on the modified code).
The success of open source is because of the contribution from more people. If more people are using the software, then the no.of people who develop/support also will increase. If we stop selected people from using the software, then we are reducing the developers/supporters of that application. If we stop industry to use a software, then we are stopping the industry to develop/support the software. Actually, industry is the one which has more money, and time to do this development. If we give one good basic application which is very useful for the industry, then industry will start developing it. And, all normal users will get the advanced features for free without any effort.
LGPL makes sure that the developments on that application will come back to open source community, and still industry can use it.
GPL makes sure that industry cannot use this application, and will take so much money and time from normal poor people, and will never kill proprietary softwares.
GNU.org contains one article on using GPL and not LGPL. obviously, that is the most ridiculous article. The link to that article is,

Can I live without google?
Around 10 years back, without power, I could do nothing.
After few years, without computer, I could do nothing.
After few years, without internet, I could do nothing.
Now, without google, I could do nothing.
I am so dependent on many google services inlcluding google search, gmail, orkut, blogger, calendar, docs/spread sheets, google reader. If tomorrow, google says these services are not free, then I may pay money to use these services. Yahoo provides many of these services. But, it is terrible. I hate to open my yahoo mail account, because it eats up my system resources, and I cannot do anything till I close that. If anybody sends mail to my yahoo account, they can be assured that, I will never reply.
Is there anybody who is going to beat google in the near future, or will it become another indispensable? I hope it won't become like microsoft and yahoo, and provides all it's services for free with the same efficiency.

How does management work?
Worker : Sir, I want a hammer to hit a nail. Please, provide me a hammer.
Director : No. I want you to use a laptop instead of a hammer. Laptop is more efficient, and it has multiple uses.
Worker : No Sir. I want only hammer. Laptop is useless.
Director : I don't accept you to buy a hammer. I want you to buy only a laptop.
Worker goes to the manager.
Worker : Sir, I want to buy a hammer, and the director is not accepting me to buy one. He asked me to buy a laptop instead.
Manager : Then, buy laptop only.
Worker : How can I use laptop for hitting the nails. It is useless for me.
Manager : If there is any problem, then give enough data to the director to support why you need a hammer.
Worker : What data to give? I just need a hammer to hit a nail. I cannot understand what you are talking.
Manager : Ok. I understand your situation. What is the cost of the hammer?
Worker : Around Rs.100.
Manager : What is the cost of the laptop?
Worker : Around Rs.40,000.
Manager : Can you use a hammer efficiently to hit a nail?
Worker : Yes.
Manager : Can you use a laptop efficiently to hit a nail?
Worker : No.
Manager : Why?
Worker : It is not very easy to hit a nail. It does not have a handle to use. The density of the laptop is very less when compared to the density of hammer.
Manager : If I provide a handle to the laptop, can you use it?
Worker : No. Laptop is too big to use it. Still it is not strong enough to hit a nail.
Manager : If I provide small laptop which is very heavy, does it solve your problem?
Worker : No. I just want a hammer.
Manager : What is the life time of a hammer?
Worker : Easily more than 10 years.
Manager : What is the life time of a laptop?
Worker : If we use this to hit nails, it will be useless after a day or two.
Manager : Can we use hammer for any other purpose other than hitting nails?
Worker : hmm. No. We cannot use it for any other purposes.
Manager : Can we use laptop for any other purposes?
Worker : Ya. All the senior software engineers need one laptop. They keep one laptop with them always.
Both manager, and worker goes to the director.
Manager : Sir, our worker wants to buy a hammer. He told me that you suggested laptop. I evalutated both the options. Here is the summary.
Hammer costs only Rs.100, and we can use it for more than 10 years. This is easy to use. It also has a handle. But, the disadvantage is, we cannot use this for any other purpose.
Laptop costs around Rs.40,000. It has so many uses. All our software engineers need one laptop, and they keep one with them always. It has high usage. But, it is not as efficient as hammer for hitting nails. It does not have a handle, and it is not strong enough. We can provide a handle, and buy a small and heavy laptop. Still, it won't be as efficient as a hammer. Not only that, if we use laptop to hit nails, it will break easily, and will be unusable. Life time of the laptop is just in the order of the days.
Director : It seems hammer is more cheaper and efficient than laptop for this purpose.
Manager : Yes. It is more cheaper and efficient.
Director : Then, buy a hammer.
Manager : Thank you sir.
Director : No. I want you to use a laptop instead of a hammer. Laptop is more efficient, and it has multiple uses.
Worker : No Sir. I want only hammer. Laptop is useless.
Director : I don't accept you to buy a hammer. I want you to buy only a laptop.
