red-faced gentleman

I know a planet where there is a certain red-faced gentleman. He had never smelled a flower. He has never looked at a star. He has never loved any one. He has never done anything in his life but add up figures.

essential things

The essential things in life are seen not with the eyes, but with the heart.

You are attempting with incorrect version of javac in Ubuntu while building android source code


I have copied the JRE & JAVA SDK folder and set the environment variable . (without installing java, make it as
like an installed). with this one, I am able to compile android checkout.
I have checked the version of the java. its version is JDK_1.0.5_19;
Once I tried to install eclipse, then old version or updated version is installed in my laptop ,
so I couldnt be able to compile android source code and got the error as follows:

Error: You are attempting with incorrect version of javac in Ubuntu while building android source code

We can get current java version by typing "java -version". I found that the java version is different from working version (android compiled code);
So we have to remove the recently installed version and reinstall the java .

We have to search the recently installed version by typing the command:

"aptitude search jdk"

it will lists out the JDK packages.

Remove all the JDK packages (Our JDK package doesnt need installation) by typing the following command:

aptitude purge $1 ($1 is the package listed in "aptitude search jdk")

install java_1_5_0_19 .bin file and then now try recompiling the code.Now it is working.

Environment variable was not set in Ubuntu


 if we are setting the environment variable PATH, its value is not reverted back to last value once the
terminal is closed.

To overcome this problem, we need to set the environment variable in
.bashrc file in root folder.

Chetan Bhagat speech at symbiosis

Following is the speech by Chetan Bhagat given at the orientation programme for the new batch of MBA students at Symbiosis, Pune.

Good Morning everyone and thank you for giving me this chance to speak to you. This day is about you. You, who have come to this college, leaving the comfort of your homes (or in some cases discomfort), to become something in your life. I am sure you are excited. There are few days in human life when one is truly elated.  The first day in college is one of them.  When you were getting ready today, you felt a tingling in your stomach. What would the auditorium be like, what would the teachers be like, who are my new classmates – there is so much to be curious about. I call this excitement, the spark within you that makes you feel truly alive today. Today I am going to talk about keeping the spark shining. Or to put it another way, how to be happy most, if not all the time.

Where do these sparks start? I think we are born with them. My 3-year old twin boys have a million sparks. A little Spiderman toy can make them jump on the bed. They get thrills from creaky swings in the park. A story from daddy gets them excited. They do a daily countdown for birthday party – several months in advance – just for the day they will cut their own birthday cake.

I see students like you, and I still see some sparks. But when I see older people, the spark is difficult to find. That means as we age, the spark fades. People whose spark has faded too much are dull, dejected, aimless and bitter. Remember Kareena in the first half of Jab We Met vs the second half? That is what happens when the spark is lost.   So how to save the spark?

Imagine the spark to be a lamp's flame. The first aspect is nurturing – to give your spark the fuel, continuously. The second is to guard against storms.

To nurture, always have goals. It is human nature to strive, improve and achieve full potential. In fact, that is success. It is what is possible for you. It isn't any external measure – a certain cost to company pay package, a particular car or house.

Most of us are from middle class families. To us, having material landmarks is success and rightly so. When you have grown up where money constraints force everyday choices, financial freedom is a big achievement. But it isn't the purpose of life. If that was the case, Mr. Ambani would not show up for work. Shah Rukh Khan would stay at home and not dance anymore. Steve Jobs won't be working hard to make a better iPhone, as he sold Pixar for billions of dollars already. Why do they do it? What makes them come to work everyday? They do it because it makes them happy. They do it because it makes them feel alive Just getting better from current levels feels good. If you study hard, you can improve your rank. If you make an effort to interact with people, you will do better in interviews. If you practice, your cricket will get better. You may also know that you cannot become Tendulkar, yet. But you can get to the next level. Striving for that next level is important.

Nature designed with a random set of genes and circumstances in which we were born. To be happy, we have to accept it and make the most of nature's design. Are you? Goals will help you do that. I must add, don't just have career or academic goals. Set goals to give you a balanced, successful life. I use the word balanced before successful. Balanced means ensuring your health, relationships, mental peace are all in good order.

There is no point of getting a promotion on the day of your breakup. There is no fun in driving a car if your back hurts. Shopping is not enjoyable if your mind is full of tensions.

You must have read some quotes – Life is a tough race, it is a marathon or whatever. No, from what I have seen so far, life is one of those races in nursery school, where you have to run with a marble in a spoon kept in your mouth. If the marble falls, there is no point coming first. Same with life, where health and relationships are the marble. Your striving is only worth it if there is harmony in your life. Else, you may achieve the success, but this spark, this feeling of being excited and alive, will start to die.

One last thing about nurturing the spark – don't take life seriously. One of my yoga teachers used to make students laugh during classes. One student asked him if these jokes would take away something from the yoga practice. The teacher said – don't be serious, be sincere. This quote has defined my work ever since. Whether its my writing, my job, my relationships or any of my goals. I get thousands of opinions on my writing everyday. There is heaps of praise, there is intense criticism. If I take it all seriously, how will I write? Or rather, how will I live? Life is not to be taken seriously, as we are really temporary here. We are like a pre-paid card with limited validity. If we are lucky, we may last another 50 years. And 50 years is just 2,500 weekends. Do we really need to get so worked up? It's ok, bunk a few classes, goof up a few interviews, fall in love. We are people, not programmed devices.

I've told you three things – reasonable goals, balance and not taking it too seriously that will nurture the spark. However, there are four storms in life that will threaten to completely put out the flame. These must be guarded against. These are disappointment, frustration, unfairness and loneliness of purpose.

Disappointment will come when your effort does not give you the expected return. If things don't go as planned or if you face failure. Failure is extremely difficult to handle, but those that do come out stronger. What did this failure teach me? is the question you will need to ask. You will feel miserable. You will want to quit, like I wanted to when nine publishers rejected my first book. Some IITians kill themselves over low grades – how silly is that? But that is how much failure can hurt you. But it's life. If challenges could always be overcome, they would cease to be a challenge. And remember – if you are failing at something, that means you are at your limit or potential. And that's where you want to be.

Disappointment' s cousin is  Frustration, the second storm.  Have you ever been frustrated? It happens when things are stuck. This is especially relevant in India. From traffic jams to getting that job you deserve, sometimes things take so long that you don't know if you chose the right goal. After books, I set the goal of writing for Bollywood, as I thought they needed writers. I am called extremely lucky, but it took me five years to get close to  a release. Frustration saps excitement, and turns your initial energy into something negative, making you a bitter person. How did I deal with it? A realistic assessment of the time involved – movies take a long time to make even though they are watched quickly, seeking a certain enjoyment in the process rather than the end result – at least I was learning how to write scripts, having a side plan – I had my third book to write and even something as simple as pleasurable distractions in your life – friends, food, travel can help you overcome it. Remember, nothing is to be taken seriously. Frustration is a sign somewhere, you took it too seriously.

Unfairness – this is hardest to deal with, but unfortunately that is how our country works. People with connections, rich dads, beautiful faces, pedigree find it easier to make it – not just in Bollywood, but everywhere. And sometimes it is just plain luck. There are so few opportunities in India, so many stars need to be aligned for you to make it happen. Merit and hard work is not always linked to achievement in the short term, but the long term correlation is high, and ultimately things do work out. But realize, there will be some people luckier than you. In fact, to have an opportunity to go to college and understand this speech in English means you are pretty damm lucky by Indian standards. Let's be grateful for what we have and get the strength to accept what we don't. I have so much love from my readers that other writers cannot even imagine it. However, I don't get literary praise. It's ok. I don't look like Aishwarya Rai, but I have two boys who I think are more beautiful than her. It's ok. Don't let unfairness kill your spark.

Finally, the last point that can kill your spark is Isolation. As you grow older you will realize you are unique. When you are little, all kids want Ice cream and Spiderman. As you grow older to college, you still are a lot like your friends. But ten years later and you realize you are unique. What you want, what you believe in, what makes you feel, may be different from even the people closest to you. This can create conflict as your goals may not match with others. And you may drop some of them. Basketball captains in college invariably stop playing basketball by the time they have their second child. They give up something that meant so much to them. They do it for their family. But in doing that, the spark dies. Never, ever make that compromise. Love yourself first, and then others.

There you go. I've told you the four thunderstorms – disappointment, frustration, unfairness and isolation. You cannot avoid them, as like the monsoon they will come into your life at regular intervals. You just need to keep the raincoat handy to not let the spark die.

I welcome you again to the most wonderful  years of your life. If someone gave me the choice to go back in time, I will surely choose college. But I also hope that ten years later as well, your eyes will shine the same way as they do today. That you will Keep the Spark alive, not only through college, but through the next 2,500 weekends. And I hope not just you, but my whole country will keep that spark alive, as we really need it now more than any moment in history. And there is something cool about saying – I come from the land of a billion sparks.

Multiple Target patterns error with mak files in android/linux

Gnu make looks for tab space after the target line.
For ex:
$(TARGETDIR)/test.lib : $(TEST_SRC)

The above line in.mak file would throw multiple target patterns error.

correct format would be

$(TARGETDIR)/test.lib : $(TEST_SRC)
<adding tab space here>$(group_test).
By giving  some tabspace it will compile without any problem.

Android_Out of memory error

I got a wierd problem with android emulator, I have created a virtual device through Android AVD manager (newly created emulator with platform 2.1 and api level 7), I have tried with standard settings and with added hardware parameter for larger (256 mb) device ram size but nothing changed.

I need to come files to the system partition to test a project (called haggle), but for some reason the system partition has no space from start.

aa a@aaa /home/haggle-0.2-android $ adb -s emulator-5554 shell

# df df /dev: 47084K total, 0K used, 47084K available (block size 4096) /sqlite_stmt_journals: 4096K total, 0K used, 4096K available (block size 4096) /system: 73600K total, 73600K used, 0K available (block size 4096) /data: 65536K total, 18464K used, 47072K available (block size 4096) /cache: 65536K total, 1156K used, 64380K available (block size 4096)

As you can see the system partition has 0K space available. When a connect a non-rooted HTC Nexus One and do the same I get these values:

/dev: 108896K total, 0K used, 108896K available (block size 4096) /sqlite_stmt_journals: 4096K total, 0K used, 4096K available (block size 4096) /system: 148480K total, 116364K used, 32116K available (block size 4096) /data: 200960K total, 22296K used, 178664K available (block size 4096) /cache: 97280K total, 1852K used, 95428K available (block size 4096) /sdcard: 3864064K total, 118496K used, 3745568K available (block size 32768)

When starting the emulator you can specify the partition size by -partition-size x emulator_name.

done through the terminal that is.

Example: emulator -partition-size 125 @b

What I am wondering is why the system partition on the emulator has 0K free space from beginning and what can I do to change that? Even if I make the partition write-able with mount/remount I get the same 0K values.
