Chetan Bhagat at Symbiosis
Speech by Chetan Bhagat at Symbiosis ...must read...
Hey guys,
I liked it so I am sharing it.I hope you all will like it too. "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."
"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 is 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 thing about nurturing the spark - don't take life seriously. Life is not meant 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, scoring low in couple of papers, goof up a few interviews, take leave from work, fall in love, little fights with your spouse. We are people, not programmed devices........." :)
"Don't be serious, be sincere."!!

Back to Gym
Four months after, I stepped into gym. Each gym friends felt I left the company. I was lost the sync to gym after my sister's marriage. Earlier I was regular about two years.
Body is badly... paining. Now I took resolution not miss a single day.
Am I right?

A patent and Power Management in Small Gadgets
Can silly idea change the world? Certainly! There are many examples in the history. Here is a simple story. Don’t neglect basic mathematics and physics where ever you are…
It is a story of patent (Patent # 5280371, Directional Diffuser for a Liquid Crystal Display) made by an MNC. The same technology is now being used in smart systems. It was developed to minimize the scattered light from the source and to increase light rays directionality. However, the saving might be small percentage in case of large displays. On mobile displays the saving will be considerable.
Basis:
An aircraft (civil/military) will be equipped with the state-of-the-art electronics ranging from Flight Controls, Displays, Flight Management Systems, Servos, etc. All these systems needs high power generators, usually the aircraft engines will generate large power compared to small systems.
These display systems will be having CRT, LED or LCD based monitors. Except CRT, the other two requires less power, order of few tens of watt. Then why do we need to save small quantity of power (due to scattered light rays) in LCD display? We are engineers, be smart! J
An LED is active display that emits light on power (just remember, it will replace entire lighting systems in near future. The CFL technology is an alternative). Where as, an LCD is passive display, which requires external light source (backlight) for illumination. Based on viewing angle the light will be scattered to sides and vertical direction.
The idea here is to minimize the scattered light to sides, since the display is required only to the pilot. It was achieved using basic physics principles. We use convex lens to direct light on single point. How can it be made directional? (Hint: An array of convex lenses).
The same principle is used in mobile displays, PDAs, iPod, etc. The MNC licenses the technology to the required companies.

How I Got Addicted to Embedded System Development?
First I am thankful to E-Learning center of
I still hear some pessimistic opinions about development of embedded systems in
I believe embedded development requires dedicated learning and multidisciplinary engineering skills. It is always suggested to learn from experts, other engineers and from our own experiences.
I have collected an article long ago, same presented here. Infact, my imagination about the future of embedded systems is much advanced than what the article covers. I am not sure of the statistical data given at the end, after observing the offers that I am getting from various Indian giants I believe the figures might be correct.
Just read on…

Embedded systems: can
5 Jan, 2005, 0007 hrs IST, Pradeep Kurup, INDIATIMES NEWS NETWORK
Embedded systems technology is a field that is fast making waves in the Infotech world.
Though many developed countries have made huge strides in the technology, the huge skill requirement coupled with essential working experience and infrastructure needed for the sector has made
The technology that has become a part of everyday life has thrown open huge opportunity, though countries like Japan, Thailand and South Korea have made huge strides dealing with the predecessor to embedded systems technology, i.e. microprocessor.
But, as the world gets logged on to more and more Internet applications in everyday life, the computing technology needs to keep pace by mastering a technology that will looks beyond microprocessor.
So, the need is applications that are manageable, adaptable, scalable, and flexible.
What are embedded systems?
Embedded systems are combination of computer hardware and software, and perhaps additional mechanical or other parts, designed to perform a dedicated function.
In some cases, embedded systems are part of a larger system or product, as in the case of an antilock braking system in a car. Contrast with general-purpose computer.
Embedded systems are the applications that fuel some of the microprocessors that play a hidden but crucial role in our everyday lives.
An embedded system consists of two components: a compact, ultra reliable operating system that controls the microprocessor inside a device, and the suite of applications that runs on the operating system.
VLSI is just about chip design, designing hardware, whereas embedded systems are a composite solution of creating software for a given hardware to deliver required functionality.
Where are embedded systems mostly used?
Embedded systems are fast and smart microprocessors, smaller in size, that are the very life of home appliances.
Embedded systems have revolutionized home electronics by making them smarter.
The future of home electronics industry is the link with Internet, so that they become operational from anywhere. This will be helped by advances in embedded systems.
Embedded systems find application in microwave ovens, cell phones, calculators, digital watches, VCRs, cruise missiles, GPS receivers, heart monitors, laser printers, radar guns, engine controllers, digital cameras, traffic lights, remote controls, bread machines, fax machines, pagers, cash registers, treadmills, gas pumps, credit/debit card readers, thermostats, pacemakers, blood gas monitors, grain analyzers, and what not.
What's the market for embedded systems?
The world market for embedded systems development is around $25 billion and is expected to grow at a CAGR of 16%.
The embedded systems technology was $250 million industry in 1998.
Cisco, Wind River Systems, Sun Microsystems, Integrated Systems, Microware Systems, and QNX Software Systems are among the prominent developers of embedded systems.
According to a study, Future of Embedded Systems Technologies, the market for embedded systems is expected to grow at an average annual growth rate (AAGR) of 13% over the period.
The market for embedded systems are divided into 4 segments, namely, embedded software, embedded processors, embedded boards and embedded memory.
Embedded processors are divided into microcontroller (MCU), microprocessor (MPU), and digital signal processor (DSP) segments.
Embedded Memory includes various types of random access memory (RAM) and programmable read-only memory (PROM) memory, as well as flash memory.
Software for embedded applications which includes real-time operating systems and portable operating systems will grow at an AAGR of over 16%. Both Microsoft and Sun have entered the embedded systems marketplace with their Windows CE and Java offerings respectively.
Embedded processors, the largest segment in terms of revenue, will grow at 11.2% on average per year.
Market for embedded memory products will rise at an AAGR of 17.7%.
Embedded boards will see a respectable AAGR of 13.1%.
Why's the market for embedded systems booming?
Embedded products are no more limited just to the high-end technology related tools. They are very much an integral part of our life today.
Everyday home appliances, phones, toys, entertainment systems and printers, though find extensive use of embedded systems, are first generation systems.
The advent of the internet and the need for convergence has ushered a new era in the field of embedded systems.
The modern-day embedded processors are being designed specifically for Net-centric markets.
The emerging embedded processors will ensure new CPU architectures that promise high-end performance and customization.
Analysts are of the view that the next generation hardware and software supported by embedded technology will be more manageable, adaptable, scalable, and flexible.
The embedded systems applications will branch out areas as diverse as wireless, internet and mobile communications, industrial control, test and measurement, networking, aerospace and automotive control, consumer electronics, digital imaging and defense.
What's the future of embedded systems in
At present
Apart from Infotech services companies, substantial embedded systems development is being done by multinationals such as Texas Instruments and Intel.
Embedded system requires considerable domain knowledge, say in automotive, telecom or medical for which the system has to be designed.
15% of HCL staff is working on embedded systems. It contributes more than 30% of HCL Technologies revenues.
The high level of technological and domain skills required by embedded system are available in
TCS is fast moving up the value chain. The largest software exporter of the country has been developing embedded systems for overseas as well as domestic clients. Now, along with the outsourced operations, TCS is planning to design embedded systems itself.
Seeing the huge market potential, TCS will be manufacturing the systems in a fabrication unit located elsewhere and marketing it in the
