* Life's Simple Advice *

* Do not walk behind me for I may not lead. Do not walk ahead of me, for I may not follow. Do not walk beside me either. Please, just get the hell out of here and leave me alone.

* Good judgment comes from bad experience and bad experiences come from what you thought was a good judgment.

* In a hierarchy, every employee tends to rise to his level of Incompetence. Work is accomplished by those employees who have yet to reach their level of incompetence.

* If you want a winning team for the high jump, you find one person who can jump seven feet at once, not seven people who can jump one foot each and try to mount on top of each other.

* The quickest way to double your money is to fold it in half and put it back in your pocket. Similar way you can quadruple.

* Those who can do, cannot teach. Those who can't teach, administer. Those who cannot even administer, finally become successful consultants.

* Everybody lies. But does it really matter? Nobody listens anyway.

* Your learning ability goes down when your lips are moving. Faster the lips movement, slower the learning ability.

* Experience usually arrives late and only after you had just needed it a few moments back.

* The challenge in solving of the problem lies in finding the right solvers.

* If anything can go wrong, it will do so in multiple forms.

* Important telephone rings when you are on toilet seat without phone.

* The probability of your meeting someone you know increases when you are with someone you don't want to be seen with.

* Great discoveries are made by stupidity of mistakes. Go ahead screw up.

* Promotion is hard for irreplaceable. If you can be replaced than you can be promoted.

* If you think nobody cares that you are alive, try missing a couple of car payments.*

Emergency No.(ICE) in Mobile Phone

We all carry our mobile phones with numerous names & numbers stored in its memory. But nobody, other than ourselves, knows which of these numbers belong to our closest family or friends.

If we were to be involved in an accident or were taken ill, the people attending on us would have our mobile phone but wouldn't know who to call. Yes, there are hundreds of numbers stored; but which one is the contact person in case of an emergency? Hence this 'ICE' (In Case of Emergency) Campaign.

The concept of 'ICE' is catching on quickly. It is a method of contact during emergency situations. As cell phones are carried by the majority of the population, all you need to do is store the number of a contact person or persons who should be contacted during emergency under the name 'ICE' ( In Case of Emergency).

The idea was thought up by a paramedic who found that when he went to the scenes of accidents, there were always mobile phones with patients, but they didn't know which number to call. He therefore thought that it would be a good idea if there was a nationally recognized name for this purpose. In an emergency situation, Emergency Service personnel and hospital Staff would be able to quickly contact the right person by simply dialing the number you have stored as 'ICE.'

For more than one contact name, simply enter ICE 1, ICE 2 and ICE 3 etc. A great idea that will make a difference!

Let's spread the concept of ICE by storing an ICE number in our mobile phones today !!!

Please forward this. It won't take too many 'forwards' before everybody will know about this. It really could save your life, or put a loved one's mind at rest .

ICE will speak for you when you are not able to do so.

The megapixel myth

A few month back someone ask me what camera he should buy. His requirement was to have at least 7 mega pixel camera. I had taugh time explaning to him that image resolution(number of pixel) has little to do with image quality. I don't know which camera he brought. To me a 3 mega pixel is enough for daily used unless am trying to print a wall size picture.

There are many people who have the same perception about mega pixel.Let me try to explain why megapixel has nothing to do with picture quality.

Pixel is the smallest element representing a picture. Pixel stand for picture element. They are arranged horizontally and vertically.

Megapixel (pixel count) is the multiplication of horizontal pixel with the vertical pixel. So a 3 MP will have
2,048 (horizontal) x 1,536 (vertical) pixels, or 3,145,728 pixels. Megapixel are a square function so a small difference in megapixel are unimportant. A 40% increase in horizontal pixel double the pixel count. So a double pixel count increase the real horizontal pixel by 40%.

Image Resolution:
Image resolution is how much pixel are stored horizontally and vertically in a storage medium. A 3 MP camera will have 2048 pixel horizontally and a 14 MP camera will have 4500 pixel. The vertical pixel are much lower. There is no much difference between the number of pixel stored.

Print Resulution:
Print resolution how much pixel you have per inch in the print paper. Most print will have 300 dpi (dot per inch). This did not have anything to do with the camera.

The Myth:

The myth that a higher megapixel camera has better quality then a lesser megapixel camera was created by camera makers. They used is because its easy to increase the megapixel. A 40% increase in linear pixel double the megapixel.
Manufacturer tend to squeeze a large pixel in a small image sensor, which tend to degrade the pixel quality.So more important then megapixel is the pixel quality. A more sensitive high quaity image sensor with lower megapixel will give better image then a higher megapixel.

NB: if you are interested in buying my camera let me know hehehehe

Can engineers be 'Touchy feely'?

Can engineers be 'Touchy feely'? Apparently they can... says author Chetan Bhagat

I remember the incident - I was in a restaurant, and one girl in our group
was especially charming. So I, like any other male, tried to put on a
wooing act. You know the routine, a nanosecond extra eye contact, a few
more nods to whatever she says, and attempts to throw in those
one-liners which you know you wouldn't if she weren't there.
And it seemed to be working. She leaned forward when she spoke to me,
and every now and again, we'd have a small conversation of our own, separate
from our group. She laughed at my approach with the fork and knife, and
I teased her about her hair band, which had little teddy bears. Yes, we
were flirting. A while later, she asked me the question - what did I study?
I said engineering, without any particular meaning attached to it. And
then like a cold metal rail, she went stiff. My jokes weren't funny any more.

Her eyes wandered to everyone else. What was it?

Why? Why? Why?

Two days later, I still couldn't get over my great start that had
dissipated listlessly upon mentioning my education. Engineer? What was
wrong with that? My mom had wanted me to become one since I was five!
I had to call her. 'So what happened to you that day, hot and cold,
missie?' And then she said, trying to be nice, 'Well, it's just that I am
skeptical about engineers as friends. I don't know, they can be, you know, very
logical and everything... not very touchy feely'.

Not touchy-feely. Now what the heck did that mean? Well, she obviously
did not mean it literally, since girls don't really suggest that sort of
stuff, certainly not in the first meeting across the table. I guessed it
was something to do with feelings, sort of having an emotional side. The
stereotype being, the nerdy guy who sees relationships like laws of
physics, to whom love is just a bunch of chemicals going crazy in your
brain, and getting to know a person means obtaining their bio-data.

It's time to set the record straight.
It's true that a lot of what engineers study (and they end up studying
quite a lot), has to do with formulaes, laws and numbers. No matter how
hard we try, some of the vocabulary we read all day gets into our
language. So when my mother said, 'Are you getting married next year or
not?' I was liable to say, 'Well, at this moment in time, the
probability is relatively low,' and felt it was completely normal to say it. And
when my sister went sari shopping and couldn't explain the shade she wanted,
I told the shopkeeper the percentages of pink, orange and red in the sari.

Yet, ladies, I don't think we're bad at relationships, love and getting
to know people. We too, can be touchy-feely, as that is part of our
education as well. The reason for this is that most engineering students live in
the ultimate educator - boy's hostels. Now, let me explain how this plays
into this 'touchy-feely' thing. Relationships. Imagine eating, sleeping,
brushing your teeth, bathing (ok rarely this one) and partying with the
same people all the time. So, when you are kicking that bathroom door
down for the tenth time, or when you stand in line for 'gulab-jamuns' in the
mess, and when you are done with the vodka bottle and sharing all your
secrets, you know it is good practice. Yes, hostels maketh the man.

So, next time you are in a flirtatious situation with the techno types,
go on, flirt a bit more. Of course, I am biased towards my kind, but if you
find the conversation turning too geeky, just ask them, 'So, what were
your hostel days like?' and chances are, you'll see a heart behind the
calculator. Coming back to my missie, I thought of what would make me
win her over. Flowers... too cheesy. Music... don't know her taste (nor
trust mine). Teddy bears... don't even go there. Desperate for some good
lines, I just turned it right back at her. 'Yes, I know what you are saying
about engineers. The thing is, unless people with depth like you start hanging
out with us, we won't get any better. Can you meet me some time for some
touchy/feely... oops, I mean coffee/tea?' She giggled. When they giggle,
you have won. Hence proved.

Sugar in the tea

I used to drink tea in office with friends. The usual cup of tea which i used to drink include a spoon of sugar, two tea bags, milk powder and water.
The other day i thought i will drink my tea without milk and sugar. The test was not what i expected, it was bitter and i couldn't swallow it. I have to add sugar to make it sweet.

The tea bag give color to the tea. It give good aroma. By itself it did not give any test to the tea.
Sugar give test to the tea. It make the tea complete. It did not add anything to the appearance to the tea.

In life we could be like tea bags which give color to the tea but test bitter or we could be like the sugar which is invisible
but make the tea sweet.

We can be like the sugar in the tea and make the life of people around us sweet. We don't need to be the most visible part of someone life. We could do it without being visible like the sugar in the tea.

Four years of Professional life

I have never imagine i'll be staying in the same company for four years.
On 15th july 2007 i completed four years of my professional life hear at Atrenta India Pvt (Ltd).
What more can i say then thanking God for guiding me through these years.

I graduate from Delhi College of Engineering in Electronic and communication in june 2003.
I join Atrenta on the 15th of july 2003 as a software engineer. In the four years of my professional life
i have learn lots of things, met different people and visited places i never imagine i'll see.

I dont know why i stay in the same company for fours years while people move on within a year.
It could be the kind of work i did here, it could be the independence i get working here. I came to office whenever i want.
Nobody bother me unless i dont complete on dateline.

In four years i have move from software engineer to senior software engineer and now to lead engineer. I have got
offer from telecommunication consultant india (PSU) which i refuse. The reason i didnt join is i dont like the work.

I thank God, friends and my mentor here at Atrenta for making my stay such a pleasurable experience. I hope to get more experience in future.
