How to Solve it by G.Polya

1. UNDERSTANDING THE PROBLEM
   • First. You have to understand the problem.
   • What is the unknown? What are the data? What is the condition?
   • Is it possible to satisfy the condition? Is the condition sufficient to determine the unknown? Or is it insufficient? Or redundant? Or contradictory?
   • Draw a figure. Introduce suitable notation.
   • Separate the various parts of the condition. Can you write them down?
2. DEVISING A PLAN
   • Second. Find the connection between the data and the unknown. You may be obliged to consider auxiliary problems if an immediate connection cannot be found. You should obtain eventually a plan of the solution.
   • Have you seen it before? Or have you seen the same problem in a slightly different form?
   • Do you know a related problem? Do you know a theorem that could be useful?
   • Look at the unknown! And try to think of a familiar problem having the same or a similar unknown.
   • Here is a problem related to yours and solved before. Could you use it? Could you use its result? Could you use its method? Should you introduce some auxiliary element in order to make its use possible?
   • Could you restate the problem? Could you restate it still differently? Go back to definitions.
   • If you cannot solve the proposed problem try to solve first some related problem. Could you imagine a more accessible related problem? A more general problem? A more special problem? An analogous problem? Could you solve a part of the problem? Keep only a part of the condition, drop the other part; how far is the unknown then determined, how can it vary? Could you derive something useful from the data? Could you think of other data appropriate to determine the unknown? Could you change the unknown or data, or both if necessary, so that the new unknown and the new data are nearer to each other?
   • Did you use all the data? Did you use the whole condition? Have you taken into account all essential notions involved in the problem?
3. CARRYING OUT THE PLAN
   • Third. Carry out your plan.
   • Carrying out your plan of the solution, check each step. Can you see clearly that the step is correct? Can you prove that it is correct?
4. Looking Back
   • Fourth. Examine the solution obtained.
   • Can you check the result? Can you check the argument?
   • Can you derive the solution differently? Can you see it at a glance?
   • Can you use the result, or the method, for some other problem?

• One often finds his destiny on the path he takes to avoid it.

• [repeated lines] There are no accidents.

• Your mind is like this water my friend, when it get's agitated it becomes difficult to see. But if you allow it to settle the answer becomes clear.

• Quit. Don't quit. Noodles. Don't noodles. You are too concerned with what was and what will be. There's a saying. Yesterday is history, tomorrow is a mystery, but today is a gift. That is why it is called the "present".

Illegal stack operations

Illegal Stack Operations

Illegal stack operations can lead to hard to detect crashes. This typically takes place when a program passes a pointer of the wrong type to a function. The example given below shows a case of a function expecting an integer pointer and the caller passes a pointer to a character.

http://www.eventhelix.com/realtimemantra/Basics/debugging_software_crashes.htm

char pointer/int pointer mixup

main() { char count; // The routine expects a int pointer but a char pointer has been passed // Older compilers and non ANSI C compilers do not catch this error GetCount(&count); // The called function was expecting an int (say 4 byte) variable. It was // however passed a char pointer with one byte space. GetCount will still // write four bytes, thus corrupting local variables or parameters on the // stack } bool GetCount(int *pCount) { . . . *pCount = returnValue; return true; }

what these functions will do in socket programming [ htons(), htonl(), ntohs() and ntohl() ]

By Order of the Realm! There shall be two byte orderings, hereafter to be known as Lame and Magnificent!

I joke, but one really is better than the other. :-)

There really is no easy way to say this, so I'll just blurt it out: your computer might have been storing bytes in reverse order behind your back. I know! No one wanted to have to tell you.

The thing is, everyone in the Internet world has generally agreed that if you want to represent the two-byte hex number, say b34f, you'll store it in two sequential bytes b3 followed by 4f. Makes sense, and, as Wilford Brimley would tell you, it's the Right Thing To Do. This number, stored with the big end first, is called Big-Endian.

Unfortunately, a few computers scattered here and there throughout the world, namely anything with an Intel or Intel-compatible processor, store the bytes reversed, so b34f would be stored in memory as the sequential bytes 4f followed by b3. This storage method is called Little-Endian.

But wait, I'm not done with terminology yet! The more-sane Big-Endian is also called Network Byte Order because that's the order us network types like.

Your computer stores numbers in Host Byte Order. If it's an Intel 80x86, Host Byte Order is Little-Endian. If it's a Motorola 68k, Host Byte Order is Big-Endian. If it's a PowerPC, Host Byte Order is... well, it depends!

A lot of times when you're building packets or filling out data structures you'll need to make sure your two- and four-byte numbers are in Network Byte Order. But how can you do this if you don't know the native Host Byte Order?

Good news! You just get to assume the Host Byte Order isn't right, and you always run the value through a function to set it to Network Byte Order. The function will do the magic conversion if it has to, and this way your code is portable to machines of differing endianness.

All righty. There are two types of numbers that you can convert: short (two bytes) and long (four bytes). These functions work for the unsigned variations as well. Say you want to convert a short from Host Byte Order to Network Byte Order. Start with "h" for "host", follow it with "to", then "n" for "network", and "s" for "short": h-to-n-s, or htons() (read: "Host to Network Short").

It's almost too easy...

You can use every combination of "n", "h", "s", and "l" you want, not counting the really stupid ones. For example, there is NOT a stolh() ("Short to Long Host") function—not at this party, anyway. But there are:

htons()	host to network short
htonl()	host to network long
ntohs()	network to host short
ntohl()	network to host long

Basically, you'll want to convert the numbers to Network Byte Order before they go out on the wire, and convert them to Host Byte Order as they come in off the wire.

How to detect memory leaks in C/C++ program ?

Answer:
Let us first see, How malloc and free works.

int * p = (int*)malloc(sizeof(int));
//malloc allocates memory and returns address to p. Let us say memory address 1000 is returned by malloc.

while freeing the memory, we will make use of the same address.

free(p); //free the memory address pointed by p [ in our case the memory address is 1000]

To detect memory leaks in a multiple file:


The concept is we have to use a Linked List to store the every malloc information.

Let us say malloc() is called in 100th line in 1.C.

At the time of malloc, We need to store the following informations in a linked list.
1.address returned by the malloc() fn
2.CPP filename [To get the c/cpp filename, we can use _FILE_ macro which will gives the cpp filename]
3.Line number at which malloc is called [_LINE_ macro gives us the line number]

Whenever we are freeing the memory, we need to check the linked list whether memory to be freed is available in where we stored the malloc() information.
if it is available in a linked list, then we need to delete that particular node and then free the memory.

Ex:
1.cpp

Line No:50: int * p = malloc(sizeof(int));
Line No:70: int* q = malloc(sizeof(int));
End of the program:
free(q);
//we forget to free the p;

For the above program, we will create the linked list with two nodes to represent two malloc info in 1.cpp.
while freeing the memory, the address to be freed will be checked with the linked list. if any node in a linked list matches, then we will remove that entry.
At the end of the program,Linked list will contains information about whichever pointer is not freed from memory.

awesome usage of function pointers in android C/C++

I have observed some awesome usage of function pointers in android C/C++. My sample application similar to that code:

#include <conio.h>

void fn( void (*seekDoneCb)() )
{
    void (*mSeekDoneCb)() = seekDoneCb;   

    (*mSeekDoneCb)();    
}

void Seek()
{
    printf("Seek()fn Called");
}

int main(int argc, _TCHAR* argv[])
{
    fn(Seek);
    getch();
    return 0;
}

Output:Seek()fn Called

How Negative values are stored in system ????

How Negative values are stored in system ????

int a = -1;
printf("Value of a:%x",a );

what will be the result ??? Can you tell me the value of it ???

Is it possible to predict this value ??


Result is:

 Value of a:0xffff ffff

Yes it is possible to predict the value of it.

Reasoning:
 
   Every bit is on or off / binary coded system. In binary coded system,
the negative values can be represented in two ways:

   1.One's complement [convert the zeroes to ones and ones to zeroes]
   2.Two's complement [ Two complement = one's complement value + 1]   


                      value of  1: 0000 0001
 One's complement to represent -1: 1111 1110 [changing the zeroes and to 1s and ones to zeroes in 0000 0001]
 Two's complement value          : 1111 1111 [1111 1110 +1]   

 To represent -1, the values will be stored as 1111 1111  in memory.



In my system, size(int) is 4 bytes.
   
To represent value 1 in Hex: 0x00000001 [ single value represents 4 bits].
         Value 1 in binary  : 00000000 00000000 00000000 00000001
One's complement for -1 in binary: 11111111 11111111 11111111 11111110
       
Two's complement for -1 in binary: 11111111 11111111 11111111 11111111
Two's complement for -1 in Hex   : 0x ffff ffff [single digit represents 4 binary digits]

In the same way, we can try for different negative values too.


int a = -1;
printf("Value of a:%x",a );

Do You Have It In You?

Do You Have It In You?

There is no single sure-shot recipe that makes an entrepreneur, but if you answer a confident 'yes' to most of these questions, then you have high chances of making it

1. Can you bear great financial risk?

Willingness to take risk is one thing, being able to bear it is another. Do you have enough savings stacked up to pay your bills in case the business does not take off? Does your spouse have an income you can fall back on?

2. Do you have a unique service or product?

What you offer need not be 'new', but it should have a value proposition in terms of time, money, or quality over existing products. In other words, even an improvement over previous products can be successful.

3. Are you passionate enough?

If you don't believe in what you are doing, chances are you will never make it. Self-belief and faith in your idea are among the key factors that make a difference to a business. Many real-world case studies confirm the power of passion.

4. Do you have adequate resources?

Can you sustain yourself till profits start rolling in? Make an estimate of probable costs and worst-case scenarios and see whether you can handle them. If you do not have the money, can you borrow it? 

5. Do you have the necessary experience?

You should start your business in an area where you have experience. This isn't mandatory, but crucial if you are starting on a small budget and cannot hire external help. Else, get someone with the required experience.

6. Are you willing to sacrifice your lifestyle?

Any business usually takes a while to succeed. You must be prepared to lead an extremely frugal life for at least a few years. This might mean few vacations, little eating out and even spending less time with the family.

7. Do you like all aspects of running a business?

Running a business means doing all the unglamorous work—from paying utility bills to running around and negotiating with people who might not be particularly excited about your idea. Are you ready to go?\

8. Are you comfortable making decisions on the spot?

With a new business, you call all the shots—and there are a lot of decisions to be made without any guidance. This instant decision-making ability is vital for success.

9. What's your track record of executing your ideas?

Examine your past objectively to see whether you have assumed leadership roles or initiated solo projects. This will give you a clear idea of where you stand when it comes to taking initiative.

***

How Much Money Do I Need?

Start-up capital means money needed till your business starts earning revenues. Assume expenses would be incurred under these heads for between six months to a year. Add 15-20 per cent for unplanned expenses.

1. Preliminary expenses Expenses incurred on initial surveys or for setting up a website

2. Professional expenses To hire professionals like chartered accountants

3. Cost of goods sold To develop a product or service or total income earned minus the profit

4. Selling and distribution expenses Expenses during the sales process

5. Marketing expenses Mainly advertisements or promotions

6. Cost of technology On mobile phones, computer hardware and software, Internet

7. Administration expenses Postage, stationery, rent, telephone and insurance

8. Salary and bonus Founders usually go without salaries for the first few years

9. One-time expenditure Permits, licenses, starting inventory, housing, among others

10. Monthly expenses Telephone bills, rent, wages and salaries and cost of advertisements

The Tight Fist

When you have a small budget, you have to make each penny count. Here is how

Running Your Office

• Work out of home, use existing infrastructure like laptops and phones—don't buy new ones.
• Buy cheap PCs and try for good deals on laptops. Don't fall for expensive warranties.
• Look for cheaper hosting and domain plans.
• Use Skype to save on phone bills.
• Take your time while selecting cell phone and Internet plans, review them on a monthly basis.
• Watch your utility bills—switch off the lights, AC, fans and other appliances when you leave.
• Print double-sided and in economy mode with lower tones to save toner; use cheaper paper.
• Rent your non-critical office equipment like ACs, photocopiers, coffee machine.
• Instal an electric hand dryer in your toilet to save on more expensive paper towels.
• Watch stationery costs—take free stationery from conferences or vendor (but don't steal!).
• Recycle scrap—keep pins, rubber bands and clips that you get in the mail.
• Instal open-source operating systems or use free cloud computing software.

Business Travel

• Stay with friends or relatives. If you must stay in a hotel, look for cheap options close to meeting locations. Share rooms with colleagues.
• Use air-miles if you have any.
• Take afternoon flights: they are cheaper.
• If you can, get a hotel industry association discount card. You can then get discounts.
• Plan travel in advance: look for deals. Try to club meetings in a particular city or part of a city.

Hiring People

• Hire people at less than market rates. Hire only if work can't be done by existing employees.
• Hire interns, freshers and train them.
• Find contacts to assist you with legal work, finances etc., instead of outsourcing such work.
• Don't outsource. Founders should have the core skill-sets to build and sell products. If not, get a person with the skill-set on board.

Managing Expenses

• Don't invest too much for future needs: think up to one year ahead.
• Change lifestyle to match cash flows.
• Create monthly budgets for expenses. Document all expenses.
• Analyse expenses on a 1-2 week basis and see what can be reduced further.
• Negotiate deals with vendors or customers to give you discounts for later benefit.
• Use the Internet extensively for advertising.

bind() function failure

Issue description:  bind() function is failed with error code -1.

RCA:[Root Cause Analysis]

  For this issue, I checked why bind () fn is failed.
Usually all the socket functions will return -1 for failure cases.
To know more about why it is failed, We can use WSAGetLastError() fn in case of windows.
But in case of unix/linux, There is no such function.
Instead the error value will be set to "errno" variable. We have to check this errno to know the failure.

Solution:
  I got the the file does not exit error.
Some junk  IP address value is passed to bind() function's input arguments. That is the reason, we observed this error.
I set the IP address as zero before bind() fn [which is working fine for successful cases, for failure cases,we are getting

junk IP addresses]

  I set the IP address to zero to resolve this issue.

Crash library address range:

Diff/Lookup Address: (78552da8-78400000) =  0x152DA8

How to calculate lookup address:

Lookup Address = (Crash address  - loadingAddress of a library)

Find crash point address Using addr2line along with Lookup address:

root@laptop:/opt/mips-4.3/bin# ./mips-linux-gnu-addr2line -e

/home/Streaming/mipsandroid/out/target/product/generic/symbols/system/lib/libopencore_player.so 0x152da8
/home/Streaming/mipsandroid/external/opencore/android/MediaControl.cpp:415
root@laptop:/opt/mips-4.3/bin#

The crash is at 415 th line in /home/Streaming/mipsandroid/external/opencore/android/MediaControl.cpp file.

Reason: Null pointer in mStack that is the reason for the crash.
The code is as below without NULL check
aResult = mStack->stackStop();

To resolve this issue, I added the below code:

 if(!mStack)
 {
  return; 
 }
 aResult = mStack->stackStop();

Buddha quotes 2

Do not believe what you have heard.
Do not believe in tradition because it is handed down many generations.
Do not believe in anything that has been spoken of many times.
Do not believe because the written statements come from some old sage.
Do not believe in conjecture.
Do not believe in authority or teachers or elders.

But after careful observation and analysis, when it agrees with reason and it will benefit one and all, then accept it and live by it.

- Gautama Buddha

buddha quotes

The secret of health for both mind and body is not to mourn for the past, nor to worry about the future, but to live the present moment wisely and earnestly – Buddha

Ground work needed before joining to work in foreign countries

This is someone's work done for Korea offer[ which is suitable to all countries.]

Let me tell you what all ground work I did before accepting an offer in
Korea:

1) I googled for Work culture in Korea. That prepared me mentally for
'long-working' hours.
2) Googling again told me that 'Seoul' is one of the 5-costliest cities
in the world and inflation is a-bit high here.
3) I mailed to all the friends in my network asking if they know
anybody who ever been to Korea? I got 10-11 references.
4) I mailed all of them 10-11 questions asking about:
a) Indian Food Availability.
b) Working hours.
c) Taxation rules. And, as consultant committed falsely that tax is
0%, I made sure that I do not have to pay any tax back in India.
d) As 95% of companies provide accommodation, I asked for
approximate 'Flat maintenance charges' + 'Water-n-Room Heating
expenses' + 'Society maintenance charges' and 'Internet/ TV/ phone/
mobile Connectivity charges'.
e) Cost of Transportation (to-from company and personal).
f) A rough estimate on eatables/ fruits spendings.
g) Kid's education (its extremely costly)....and some more.

5) Through one of my friend, who is International HR, got a rough
salary idea. She suggested me **most important** thing... To ask my
employer to provide me a 'Sample Salary-Slip' before signing the
Contract.

Indian consultants for Korea make a fool of us by telling that
Tax is 0% and your Salary will be 2-times OR 2.5-times of Indian Salary
without telling us anything about high cost-of-living!

Thanks to my employer, they provided me salary slip in KRW and U$D.
After comparing it with the Indian consultant's 'commitments', there
was a difference of ~2000 U$D!

6) As I was not going to use food-coupons of my employers, I made sure
to add KRW 5000 per day instead. Not much for him but fair enough for
me.

7) Knowing about 'Long working hours' and 'working on weekends' helped
me to CrossCheck the rules with employer. My employer mentioned KRW
50,000 for working on weekends (which they actually give to their
regular employees).

If anything is NOT mentioned in Contract, it won't be given
;)

8) Through 'Sample Salary Slip' I got to know that, after end-of-year
when I will return back the 'National Insurance Fund' amount (may range
from $1000-$1500) can be deposited into your Indian Bank account. And
you need to fill a form for that in the last week, before you leave.

9) Though Employers mention in contract OR consultants commit that
"every company has IP-phone... and u can make any number of calls from
office desk..blah...blah..." Its you who should make sure that u GET
this facility actually, through Contract.

U can always ask ur employer for a 'Rough Draft-of-Contract'
before u sign.

9) My employer is very honest. However there may exist some employers
who *may* create problems in ur last month's salary. Keep a Check on
that!

The Indian consultant started with and offer of 25K U$D p.a. (in-hand +
accom + all charges).. and finally his words were -"this is the biggest
offer any Korean company has made for your Experience-slot".
...Not that much actually... But, I am really carefree about miscellaneous spendings!

All I did was, I spent ~2-weeks in all this. Ground-Work! Afterall, its my
life... it me who is sacrificing!!!

On the contrary, when I reached here... I met 2-friends in Pyeongchon
who were looking frustrated as Consultant showed them a mirage of 2-2.5
times salary.
They didn't negotiate for anything!!!!

Maintenance charges + Internet + Food + Room-Water heating charges all
these they were paying from their pocket and worked for free on
weekends as it wasn't mentioned in contract! Unfortunately, they
breached the contract and went back to India on -ve notes! :(

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.
