Gandhi quotes

If I want to deprive you of your watch, I shall certainly have to fight for it; if I want to buy your watch, I shall have to pay for it; and if I want a gift, I shall have to plead for it; and, according to the means I employ, the watch is stolen property, my own property, or a donation.

I do believe that, where there is only a choice between cowardice and violence, I would advise violence..

I believe that nonviolence is infinitely superior to violence, forgiveness is more manly than punishment.

Jains not only strictly prohibit their members from eating any animal meat, but they go a step further. They don't allow root vegetables, such as onions and potatoes, lest some germs be attached to them.

Principles for Satyagrahis

Principles for Satyagrahis

Gandhi envisioned satyagraha as not only a tactic to be used in acute political struggle, but as a universal solvent for injustice and harm. He felt that it was equally applicable to large-scale political struggle and to one-on-one interpersonal conflicts and that it should be taught to everyone.^[17]

He founded the Sabarmati Ashram to teach satyagraha. He asked satyagrahis to follow the following principles (Yamas described in Yoga Sutra):^[18]

1. Nonviolence (ahimsa)
2. Truth — this includes honesty, but goes beyond it to mean living fully in accord with and in devotion to that which is true
3. Non-stealing
4. Chastity (brahmacharya) — this includes sexual chastity, but also the subordination of other sensual desires to the primary devotion to truth
5. Non-possession (not the same as poverty)
6. Body-labor or bread-labor
7. Control of the palate
8. Fearlessness
9. Equal respect for all religions
10. Economic strategy such as boycotts (swadeshi)
11. Freedom from untouchability

On another occasion, he listed seven rules as "essential for every Satyagrahi in India":^[19]

1. must have a living faith in God
2. must believe in truth and non-violence and have faith in the inherent goodness of human nature which he expects to evoke by suffering in the satyagraha effort
3. must be leading a chaste life, and be willing to die or lose all his possessions
4. must be a habitual khadi wearer and spinner
5. must abstain from alcohol and other intoxicants
6. must willingly carry out all the rules of discipline that are issued
7. must obey the jail rules unless they are specially devised to hurt his self respect

Rules for satyagraha campaigns

Gandhi proposed a series of rules for satyagrahis to follow in a resistance campaign:^[12]

1. harbour no anger
2. suffer the anger of the opponent
3. never retaliate to assaults or punishment; but do not submit, out of fear of punishment or assault, to an order given in anger
4. voluntarily submit to arrest or confiscation of your own property
5. if you are a trustee of property, defend that property (non-violently) from confiscation with your life
6. do not curse or swear
7. do not insult the opponent
8. neither salute nor insult the flag of your opponent or your opponent's leaders
9. if anyone attempts to insult or assault your opponent, defend your opponent (non-violently) with your life
10. as a prisoner, behave courteously and obey prison regulations (except any that are contrary to self-respect)
11. as a prisoner, do not ask for special favourable treatment
12. as a prisoner, do not fast in an attempt to gain conveniences whose deprivation does not involve any injury to your self-respect
13. joyfully obey the orders of the leaders of the civil disobedience action
14. do not pick and choose amongst the orders you obey; if you find the action as a whole improper or immoral, sever your connection with the action entirely
15. do not make your participation conditional on your comrades taking care of your dependents while you are engaging in the campaign or are in prison; do not expect them to provide such support
16. do not become a cause of communal quarrels
17. do not take sides in such quarrels, but assist only that party which is demonstrably in the right; in the case of inter-religious conflict, give your life to protect (non-violently) those in danger on either side
18. avoid occasions that may give rise to communal quarrels
19. do not take part in processions that would wound the religious sensibilities of any community

What good will they do you

However many holy words you read,

However many you speak,

What good will they do you

If you do not act upon them?

Are you a shepherd

Who counts another man's sheep,

Never sharing the way?

Read as few words as you like,

And speak fewer.

But act upon the dharma.

Give up the old ways -

Passion, enmity, folly.

Know the truth and find peace.

Share the way.

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

Situation:

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

Solution:
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

Error:

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

Solution:
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)
$(group_test)

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).

 

Solution:

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)

 

Solution:

 

 

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.

why we r studying science ?

The view is that science, good science, is at it's heart simply the satiation of our own curiosity. It is not a means to an end, we are

not trying to learn about the universe because we are trying to build faster computers or a better toaster. We are studying science because we want to know how the universe arranges itself, and appreciate its beauty.

Siege of Syracuse

During the Siege of Syracuse (c. 214–212 BC), Archimedes destroyed enemy ships with fire. Centuries later, Anthemius of Tralles mentions burning-glasses as Archimedes' weapon.^] The device, sometimes called the "Archimedes heat ray", was used to focus sunlight onto approaching ships, causing them to catch fire.

This purported weapon has been the subject of ongoing debate about its credibility since the Renaissance. René Descartes rejected it as false, while modern researchers have attempted to recreate the effect using only the means that would have been available to Archimedes.^[26] It has been suggested that a large array of highly polished bronze or copper shields acting as mirrors could have been employed to focus sunlight onto a ship. This would have used the principle of the parabolic reflector in a manner similar to a solar furnace.

A test of the Archimedes heat ray was carried out in 1973 by the Greek scientist Ioannis Sakkas. The experiment took place at the Skaramagas naval base outside Athens. On this occasion 70 mirrors were used, each with a copper coating and a size of around five by three feet (1.5 by 1 m). The mirrors were pointed at a plywood mock-up of a Roman warship at a distance of around 160 feet (50 m). When the mirrors were focused accurately, the ship burst into flames within a few seconds. The plywood ship had a coating of tar paint, which may have aided combustion.

 

 In October 2005 a group of students from the Massachusetts Institute of Technology carried out an experiment with 127 one-foot (30 cm) square mirror tiles, focused on a mock-up wooden ship at a range of around 100 feet (30 m). Flames broke out on a patch of the ship, but only after the sky had been cloudless and the ship had remained stationary for around ten minutes. It was concluded that the device was a feasible weapon under these conditions.

archimedes

archimedes tells of how he invented a method for determining the volume of an object with an irregular shape. According to Vitruvius, a new crown in the shape of a laurel wreath had been made for King Hiero II, and Archimedes was asked to determine whether it was of solid gold, or whether silver had been added by a dishonest goldsmith.^[13] Archimedes had to solve the problem without damaging the crown, so he could not melt it down into a regularly shaped body in order to calculate its density. While taking a bath, he noticed that the level of the water in the tub rose as he got in, and realized that this effect could be used to determine the volume of the crown. For practical purposes water is incompressible,^[14] so the submerged crown would displace an amount of water equal to its own volume. By dividing the weight of the crown by the volume of water displaced, the density of the crown could be obtained. This density would be lower than that of gold if cheaper and less dense metals had been added. Archimedes then took to the streets naked, so excited by his discovery that he had forgotten to dress, crying "Eureka!" (Greek: "εὕρηκα!," meaning "I have found it!")^[15]

Stress Management

A lecturer was giving a lecture to his student on stress management.

He raises a glass of water and asks the audience
"How heavy do you think this glass of water is?"
"It depends on how long you hold it."
"If I hold it for a minute, it is Ok."
"If I hold it for an hour, I will have an ache in my right arm."
"If I hold it for a day, you will have to call an ambulance."
"It is the exact same weight, but the longer I hold it, the heavier it becomes"

If we carry our burdens all the time, sooner or later, we will not be able to carry on, the burden becoming increasingly heavier.

"What you have to do is to put the glass down, rest for a while before holding it up again."

We have to put down the burden periodically, so that we can be refreshed and are able to carry on. When you return home from work, put the burden of work down. Don't carry it into your home. You can pick it up tomorrow. So Rest and Relax.

Your task is not to seek for love

Your task is not to seek for love, but merely to seek and find all the barriers within yourself that you have built against it - Rumi

Remember to appreciate all the different people in your life.

A water bearer in China had two large pots, each hung on the ends of a pole which he carried across his neck. One of the pots
had a crack in it, while the other pot was perfect and always delivered a full portion of water. At the end of the long walk from the stream to the House, the cracked pot arrived only half full. For a full two years this went on daily, with the bearer delivering only one and a half pots full of water to his house.

 

Of course, the perfect pot was proud of its accomplishments, perfect for which it was made. But the poor cracked pot was ashamed of it's own imperfection and miserable that it was able to accomplish only half of what it had been made to do.

After two years of what it perceived to be a bitter failure, it spoke to the water bearer one day by the stream. "I am ashamed
of myself, and I want to apologize to you. I have been able to deliver only half my load because this crack in my side causes
water to leak out all the way back to your house. Because of my flaws, you have to do all of this work, and you don't get full
value from your efforts," the pot said.

The bearer said to the pot, "Did you notice that there were flowers only on your side of the path, but not on the other pot's
side? That's because I have always known about your flaw. So I planted flower seeds on your side of the path, and every day
while we walk back, you've watered them. For two years I have been able to pick these beautiful flowers to decorate the table.
Without you being just the way you are, there would not be this beauty to grace the house?

 

Lessons to Learn from This Story:

 

Each of us has our own unique flaws. We're all cracked pots. But it's the cracks and flaws we each have that make our lives together so very interesting and rewarding. You've just got to take each person for what they are, and look for the good in them. Blessed are the flexible, for they shall not be bent out of shape.

Remember to appreciate all the different people in your life.

Look at each day

Look at each day as a new opportunity to be your very best. Set high goals, be honest, never say no, and work with people who share your passion for doing their best.

Be yourself

Perception

Washington, DC Metro Station on a cold January morning in 2007.  The man with a violin played six Bach pieces for about 45 minutes.  During that time approximately two thousand people went through the station, most of them on their way to work.  After 3 minutes a middle aged man noticed there was a musician playing.  He slowed his pace and stopped for a few seconds and then hurried to meet his schedule. 4 minutes later:   The violinist received his first dollar: a woman threw the money in the hat and, without stopping, continued to  walk. 6 minutes:   A young man leaned against the wall to listen to him, then looked at his watch and started to walk again.    10 minutes:   A 3-year old boy stopped but his mother tugged him along hurriedly.  The kid stopped to look at the violinist again, but the mother pushed hard and the child continued to walk, turning his head all the time.  This action was repeated by several other children..  Every parent, without exception, forced their children to move on quickly.   45 minutes: The musician played continuously.  Only 6 people stopped and listened for a short while.  About 20 gave money but continued to walk at their normal pace.  The man collected a total of $32.   1 hour:   He finished playing and silence took over.  No one noticed.  No one applauded, nor was there any recognition.    No one knew this, but the violinist was Joshua Bell, one of the greatest musicians in the world.  He played one of the most intricate pieces ever written, with a violin worth $3.5 million dollars.  Two days before, Joshua Bell sold out a theater in Boston where the seats averaged $100.   This is a true story.  Joshua Bell playing incognito in the metro station was organized by the Washington Post as part of a social experiment about perception, taste and people's priorities.  The questions raised: in a commonplace environment at an inappropriate hour, do we perceive beauty?  Do we stop to appreciate it?  Do we recognize talent in an unexpected context?   One possible conclusion reached from this experiment could be this: If we do not have a moment to stop and listen to one of the best musicians in the world, playing some of the finest music ever written, with one of the most beautiful instruments ever made..... How many other things are we missing?

Householder life in Jainism

Householder life

Lay Followers Vows

Ascetics follows five great vows absolutely in mind, speech and word. But, for those who want to live in family life and have a keen desire to lead a spiritual life, Jain ethics specify the following small vows (Anuvratas). These vows help to lay out a rational course of life and tend to lead to liberation. Those lay followers who practices anuvrats are known as anuvrati. Anuvratas are twelve in number:

1.Ahimsa Anuvrata: It means abstinence from gross injury or intentional or purposeless violence in word, thought, and deed towards himself or through others or by approving such actions committed by somebody else. In this vow they abstain from engaging in anything that is not strictly required for them.
2. Satya Anuvrata: In this vow, they abstain from gross telling of lies to fulfill their own vested interests, giving false evidence, or denying, or giving back the property of others. They also avoid speaking such truth as would be the cause of killing innocent being.

3 Achaurya Anuvrat: This means abstaining from stealing robbing, looting , thieving, plundering, misappropriating, other's property, and using dishonest and illegal means in acquiring worldly things.

4 Savadara santish: It means abstinence from sexual intercourse with anybody else but ones own wife. They avoid adultery and excessive sexual indulgence totally, and practise continence in regard to intercourse with one's own wife or husband.

5 Aparihraha Anuvrata: This means abstain from hoarding land, gold, house, cattle etc., in large scale and try to make voluntary limits on one's own needs, possessions and acquisitions such as land, real estate, gold, silver, money, other valuable goods, cattle and furniture. In this vow, they vow not to possess accumulations beyond a limited extent.

For strengthening and cultivating the effect of anuvratas, three Gunavratas and four sikshavratas have been pescribed. These seven vratas are supplementary vows. The following Gunavratas are to practiced for the whole lifelike the above five vratas to keep life on the right track.

6 Digvarta parimana: Dig means direction, vrata means a vow. It is a vow to carry out once own movement only within a restricted area. In this vow, they limit the distance up to which he will do in different spatial directions.

7 Upabhoga paribhoga parimana: This means to limit the sensual enjoyment of material things. Upabhoga means consumption of food, drink etc., which can only be used once, the paribhoga means semi-permanent articles like cloth, furniture, ornaments, buildings, etc., which can be used several times. They restricts fifteen types of sinful professions which are known as karmadana like manufacturing and supplying arms, selling meat, cutting forests, etc., twenty six articles such as food, ornaments etc. In this vow, householders limit the everyday usage of the quantity or number of food items, articles, etc.

8. Anarthadanda virati: In this vow householders abstain from all kind of purposeless violence, thinking ill of others, manufacturing or supplying of arms. This prevents themselves from indulging in those acts which are not required.
Among the seven vratas the four are called disciplinary vows or practical vows (sikshavrats). All four vrats are to be practiced repeatedly. Of the four, samayika and deshavakasika are to be observed daily while pushadhopavasa and atithisamvibhaga are observed occasionally.

9.Samayaka: This means abstinence from all sinful activities for a fixed intended period of 48 minutes known as muhurat. While sitting motionless, they perform samayaka meditation and contemplating upon there own soul with equanimity of mind.

10. Deshavakasika It means further lessening in the respect of the sphere of digvrata in certain areas and bhogopbhoga parinama for particular days and limited times. In the foregoing vows renunciation is made for the whole life, but the renunciation for a fixed time or shorter period comes under deshavakasika vrata.

11. Paushadhopavasa: In this vow, they accepts all the restrictions of the monk and pass time in meditation or religious study like a monk for one or more days by retiring household activities and keeping the fast by giving up all kind of food, drink, etc., on the eighth, fourteenth, or fifteenth day of each fortnight or month as per will.

12. Atithisamvibhaga: It means to offer food, drink, medicine and other articles to monk sand nuns with great reverence and with avoidance of all blemishes. It amounts to a sin to prepare food or other things intentionally for their sake. Before taking breakfast or lunch, householders think, wish and feel that it would be better for me if I had the chance to provide some portion of my food to the monk. This is called atithisamvibhaga. If the monk and nuns are not available, even they think about monks and nuns.

All the vows are to be observed in true spirit. By performing and practicing all these vows, and lay follower leads a righteous, spiritual, and pious life.

The Scarecrow

The Scarecrow

Once I said to a scarecrow, "You must be tired of standing in this lonely field."

And he said, "The joy of scaring is a deep and lasting one, and I never tire of it."

Said I, after a minute of thought, "It is true; for I too have known that joy."

Said he, "Only those who are stuffed with straw can know it."

Then I left him, not knowing whether he had complimented or belittled me.

A year passed, during which the scarecrow turned philosopher.

And when I passed by him again I saw two crows building a nest under his hat.

I searched for God

I searched for God among the Christians and on the Cross and therein I found Him not.
I went into the ancient temples of idolatry; no trace of Him was there.
I entered the mountain cave of Hira and then went as far as Qandhar but God I found not.
With set purpose I fared to the summit of Mount Caucasus and found there only 'anqa's habitation.
Then I directed my search to the Kaaba, the resort of old and young; God was not there even.
Turning to philosophy I inquired about him from ibn Sina but found Him not within his range.
I fared then to the scene of the Prophet's experience of a great divine manifestation only a "two bow-lengths' distance from him" but God was not there even in that exalted court.
Finally, I looked into my own heart and there I saw Him; He was nowhere else.

Don't worry be happy

Here is a little song I wrote
You might want to sing it note for note
Don't worry be happy
In every life we have some trouble
When you worry you make it double
Don't worry, be happy......

Ain't got no place to lay your head
Somebody came and took your bed
Don't worry, be happy
The land lord say your rent is late
He may have to litigate
Don't worry, be happy
Lood at me I am happy
Don't worry, be happy
Here I give you my phone number
When you worry call me
I make you happy
Don't worry, be happy
Ain't got no cash, ain't got no style
Ain't got not girl to make you smile
But don't worry be happy
Cause when you worry
Your face will frown
And that will bring everybody down
So don't worry, be happy (now).....

There is this little song I wrote
I hope you learn it note for note
Like good little children
Don't worry, be happy
Listen to what I say
In your life expect some trouble
But when you worry
You make it double
Don't worry, be happy......
Don't worry don't do it, be happy
Put a smile on your face
Don't bring everybody down like this
Don't worry, it will soon past
Whatever it is
Don't worry, be happy

Result:

This is due to missing of any dependency files.

Solution:
   You can copy the dependency files and then check once again.

Sometimes, if msvcr80.dll or msvcr80d.dll is referenced as a dependency in our exe/dependency files,
then this error might occurs.

To resolve this error, Project->Properties->Deployment->Additional files->

add the following lines:

msvcr80.dll|$(BINDIR)\$(INSTRUCTIONSET)\|%CSIDL_WINDOWS%|0;

 

Additional Files property is to copy the dependency files at the time of deployment.
The above code will copy the msvcr80.dll from our system to the target device(Windows Mobile device)'s windows folder.

 

 

 

Words of Kalidasa

Dasaratha saw many beasts as he was hunting. Although he saw a peacock fly very close to his chariot, he did not shoot his arrow. For, as the peacock spread its tail feathers before him, it reminded him of his wife's hair adorned with flowers of different kinds and how it would become disarranged during their lovemaking.

Learnings

Today I learnt two things:

1.How to load the WMP with local file ?
2.FourCC codes in AVI file format

How to load WMP with local file:
VS2005 debugger :
File path : wmPlayer
command line arguments : file://My documents//incredibles.avi






FourCC codes in AVI file:

FOURCC('0','0','d','c') - video
FOURCC('0','1','w','b') - audio

dc - indicates video stream
wb - indicates audio stream

00 - indicates the Stream number
01 - '' ''

Usually video will be the first stream and audio will be the second stream.
But For Some avi files, (Problematic avi file)

we found the audio as first stream and video as second stream.
So we need to check only the dc or wb to identify the stream type ( video or audio).

How to handle seek operation in Splitter or Source Filter ?

How to handle seek operation in Splitter /Source Filter:
-----------------------------------------------------------
1.SetPositions () called multiple times for a Single Seek operation.
2.we have to Set m_bSeeked variable in SetPositions() and Start Seek position
3.We have to store the Previous Seek value.within FillBuffer(), if m_bSeeked set,check for the seeked position and Previous seek position. if they are different, then send a seek request tostack or file parser.
So even Multiple SetPositions () ( 3 times) called for a single seek, operation from our filter we will send a seek request onceby having seeked Flag and Checking the Previous seek position with current seek position.
During Seeking, FillBuffer must not wait for any event... it must be unblocked ... ( Set Positions () fn will call flushing in all the output pins. Flushing will wait for the FillBuffer to complete its operation.

How to modify the 3gp streaming filter to read Only rtp data?

How to modify the 3gp streaming filter to read Only rtp data?
================================================
( 3gp streaming stack it will receives the rtsp and rtp data)

Solution:Quick and dirty way to do this:
===============================
Use Some SDP file to create the dummy audio and video output pin. ( We can create it with rtsp:// URL itself);
Hard code the media type, File duration (instead of the file duration configure duration as much as we need to receive data for RTP),config data in a filter .

How to get SDP file for any RTSP file?

How to get SDP file for any RTSP file?
RTSP response will have the SDP description
if we are having rtsp URL, we can open it with Quick time Player and at the same time, we can open the Ethereal to capture the net logs.
RTSP response RTSP/1.1 200 OK will have a SDP description.
Even with this SDP description and save it into SDP file and open it in Quick time, we are able to play it in Quick time

Audio goes off after seeking several times

Audio goes off after seeking several times :

When I seek several times, the audio goes off.

Reason:

After seeking, negative timestamps are set to video and audio media samples.

In case of video even though it was negative, it was rendered.But In case of audio,

it was not rendered fine because the audio is the reference clock for both video and audio.

Moreover audio and video are synchronized with this audio timestamp.

So the audio timestamp must not be negavtive, after seeking. if it is so, we cant predict the

rendering ( Sometimes it might render and sometimes it may not render)

Solution:

I modified Source filter in such a way to output positive timestamp for video and audio after seeking. Now the issue was resolved.

RegSvr32 error

 

I am able to compile the filter ; while registering I  got the following error:

---------------------------
RegSvr32
---------------------------
DllRegisterServer in D:\PushSource\Debug_Unicode\PushSource.dll failed.
Return code was: 0xc0000005
---------------------------
OK  
---------------------------

Solution:
============

 This error will come if any dependency has been removed
The problem is it doesnt have any dependency. I have checked it with depends.exe.

 

CFactoryTemplate g_Templates[3] =
{
    {
      g_wszPushDesktop,               // Name
      &CLSID_RxVideoReceiver,       // CLSID
      CRxReceiver::CreateInstance, // Method to create an instance of MyComponent
      NULL,                           // Initialization function
      &sudPushSourceDesktop           // Set-up information (for filters)
    }
};

 

I modified the above code as

CFactoryTemplate g_Templates[] =
{
    {
      g_wszPushDesktop,               // Name
      &CLSID_RxVideoReceiver,       // CLSID
      CRxReceiver::CreateInstance, // Method to create an instance of MyComponent
      NULL,                           // Initialization function
      &sudPushSourceDesktop           // Set-up information (for filters)
    }
};

Now I am not getting any errors.

 if I g_Templates[3] means, the regsvr32.exe expects the another 2 GUIDs and informations. Since it doesnt have the values,

it gives read violation error.

WindowsMobile Microsoft video renderer crashes for Odd resolution width

 

 

WindowsMobile Microsoft video renderer crashes with the following error for RGB565 data with 179x99 video resolution:

 

Data Abort: Thread=8a66da00 Proc=88a8b8b0 'wmplayer'

Odd Resolution Clip: 179x99 resolution
DecideBufferSize () size as 179x99*2
SetActualDatalength() as 179x99 * 2

Solution :
--------------
if I modified the DecideBufferSize to 180x99*2 then it is working fine.
renderer is doing some alignment for odd resolution clip is it so ?

Before giving the output to the renderer from our decoder, we need to align width and height to multiple's 0f 4 or 2;

 

Alignment to 4 :
----------------
  if( nFrameWidth & 0x03)
  {
   nFrameWidth = nFrameWidth  - ( nFrameWidth & 0x03);
  }
Alignment to 2 :
-----------------
  if(nFrameWidth & 0x01)
  {
   nFrameWidth = nFrameWidth - 1;   
  }

 

Note: I also got the above error if I do the following:

i) allocating memory size as 179x99 in DecideBufferSize()  and set the Width and height as 180x100 .

Solution:
-------------------

Search this library in Visual studio 8 installation folder.In the
following path it has that library.
D:\Program Files\Microsoft Visual Studio 8\VC\ce\bin\x86_arm

Integer division by error with Audio Decoder filter

while delivering audio data, I got a problem as follows:

i) if I deliver it then I got a crash in Decoder as "Integer division by zero".

So I modified the AvgBytesPerSec member of WAVEFORMATEX structure as follows:

wfx.nBlockAlign = 1 ;
wfx.nAvgBytesPerSec = MP3hdr->bitrate * 1000 / 8;

Solution:
--------------
Assign the proper values for WAVEFORMATEX header.

Modified value as follows Now the Filter is working fine.

wfx.nBlockAlign = 2 * nchannels ;
wfx.nAvgBytesPerSec = pwfxout->wfx.nSamplesPerSec * pwfxout->wfx.nBlockAlign ;

How to do dynamic format change from the Decoder Filter?...

 How to do dynamic format change from the Decoder Filter?...

Scenario:
-------------
 Assume that we reading video data from the RTP or from real media file.
we will receive the video with 320x240 resolution. In the middle of the stream, it might give you video data with 640x480

resolution. How will u handle the situation ? we can do it with Dynamic format change.

 

what needs to be done at decoder level:
---------------------------------------
   For getting width and height, we will refer the config data from the Source filter's VIDEOINFOHEADER config data or from
the video frame itself have the config information .

 We have the Create the Decoder with current width and height( 320x240) resolution.

DecodeFrame() fn itself must have the ability to detect new config. if some new config arrived, the DecodeFrame () returns

E_NEW_CONFIG;
 
 
 when the new width and height found, we have to delete/release the decoder ( Not a decoder filter) and we have to
create the new decoder with new resolution and then try to decode the frame.

 Here we need to change Decoder filter's output pin media type as well as the reallocate renderer's allocator with new

resolution.

 Logic is as follows:

 if( DecodeFrame() == E_NEW_CONFIG)
 {
  DeleteDecoder();
  hr =CreateDecoder(newWidth,newHeight);

  //Change the output pin's media type resolution
  //Rellocate the renderer's allocator with new resolution (640x480)

  //DecodeFrame() once again and give it out.

 }
 

 if we want the dynamic format change, we have to use upstream filter's(video renderer) allocator .

 

 

For Windows mobile:
-------------------
  Microsoft video renderer doesnt have the dynamic format change support.
So we can develop the new video renderer.

 if( DecodeFrame() == E_NEW_CONFIG)
 {
  DeleteDecoder();
  hr =CreateDecoder(newWidth,newHeight);

  //Change the output pin's media type resolution
  //Rellocate the renderer's allocator with new resolution (640x480)

  hr = m_pInput->ReceiveConnection(m_pOutput,mediatypeWithNewRes); // m_pInput is just a pointer to upstream

filter's                // input pin ( video renderer input pin

  DecodeFrame();
  Deliver(pSample);
  
 }

 
 In Video renderer:
 -------------------
  upstream filter input pin (Renderer input Pin):

  we have to override the ReceiveConnection() fn;

 HRESULT ReceiveConnection(IPin* m_Connected, AM_MEDIA_TYPE* mtWithNewRes)
 {

  if( m_Connected)
  {
                   // this condition will be satisfied if ReceiveConnection() called from the Decoder manually (while    // the graph was running
   int Width  = getWidth(mtwithNewRes);
   int height = getHeight(mtWithNewRes);

   if( CheckMediaType(mtWithNewRes) != S_OK)
   {
    return E_FAIL;
   }
   SetMediaType(mtWithNewRes);

   m_pAllocator->Decommit();
   m_pAllocator->SetProperties(Width,height);
   m_pAllocator->Commit();
    
   
  }
  else
  {
   return CBasePin::ReceiveConnection();
  }
  
 }

  
 

 
For PC:
----------
 For PC, Video renderer has the support for dynamic format change.
 

 we will do as follows:

within Decoder:
  
  if( DecodeFrame() == E_NEW_CONFIG)
 {
  DeleteDecoder();
  hr =CreateDecoder(newWidth,newHeight);

  //Change the output pin's media type resolution
  //Rellocate the renderer's allocator with new resolution (640x480)

  hr = m_pInput->ReceiveConnection(mediatypeWithNewRes);

  m_pInput->m_pAllocator->Decommit();
  m_pInput->m_pAllocator->SetProperties(new Resolution Size);
  m_pInput->m_pAllocator->Commit();

  DecodeFrame();
  Deliver(pSample);
  
 }
Renderer have the ability to change to new allocated buffer;;
