What did you learn from your B.Tech life?

My @Quora answer to What did you learn from your B.Tech life?

Answer by Abhilash Anandan:

  • You will spend for years of your time there. No matter what you think of college, love it or hate it. Just don't complain and start bitching about how much your college sucks! Thank you Geet Rose Jose for telling me this. We will just be wasting our time.
  • Placements should not be the objective of your life in college. Your objective in college should be to build a good network and to learn to network. A good network will help you get through life, not a GPA or a placement. Never stick to a network within your college.
  • A GPA of 7 is good enough to have a smooth life ahead of you. Always remember this is not a  deciding factor in lots of good places. 7 is a safe place to be, unless  you have already set your sights for places that require much higher.
  • If you have no skills; build them. I had none when I joined college.  Now I am skilled in Web Development  (HTML5/CSS3, PHP, JS), Software  Development (C/C++/QML), Image Processing (OpenCV), Presentations  (Impress, Powerpoint, Prezi, Moovly) and now I am learning Business  Development as a trainee at Techversant Infotech. I prefer being a jack  of all trades so I understand markets and requirements better rather  than a master of one. If you have no skills and no GPA, you need to have  good palm lines.
  • If relatives ask, "Did you get placed?", say YES!  Even if you haven't. But follow up with, but you'll probably not go as I  prefer to work at start ups or go for higher education!
  • B. Tech in a college away from home is a good idea as it makes you more independent. But, it completely depends on you and your family. Family first.
  • I learnt to send professional E mails, make good letters and most importantly, how to negotiate with stubborn people (faculty and management) who make no sense at times!
  • If  I had high speed Internet Connection at home for 4 years, I could have  (but probably wouldn't have) achieved far more than I have learned and  achieved in college. I would've saved lots on money as well. But, I DO NOT RECOMMEND THIS!
  • You must get at least four arrears in college. You will learn how to handle pressure. This comes from a person who is proud of the fact that in my final year I wrote  and passed 16 theory papers + 2 labs + Final year project (awarded most  socially relevant project) + Another Govt. funded project + Seminar  (3rd highest score in my Department) + Prizes at various national level  innovation competitions held at Kolkata and Kerala. I was also part of a  start up, but not so much during final year. And I was the first person to start working after college (interview next day and joined the next)
  • I learnt if you have the will, you can achieve whatever you want in life.
  • You need to have a good social profile (Facebook, LinkedIn) that will impress companies you intend to work for. Be careful of what you post.
  • You DO NOT need to study very hard to pass B. Tech. You need to study hard to get a good GPA. 7 is not very hard to get.
  • DO NOT give in to peer pressure. You need to have a voice of your own.
  • Always lead from the front and take part in all college activities and functions (even if you hate college). If you hate college, make most use of college. Learn as much as you can. These events will give you much needed skills and can help you build a good network.
  • The Real World Does Not Suck. Have a good network and you will be respected all through life.
  • Ask and learn from the life experiences of the faculty. You will be amazed at the insight they can share.
  • You will get to know the different forms of love. Boy/Girlfriend. Ex-Boy/Girlfiend. Family. Teachers.
  • If you fail to plan, you are planning to fail. 2nd year in college is high time you decide what you want to do with your life! Class X – XII was the right time. But, since you started B. Tech, the time is now!
  • Always keep in mind that everything that happens is for our own good. This way, you can stay positive all the time. Remove negativity from your life.
  • Always have a backup of everything!

Good luck!

Please do let me know your comments. If you agree or disagree. Or if you want me to include anything more.

I thank all my friends (especially the ones who have hurt me) for making me what I am now.

Google has always been at the pinnacle when it comes to innovative commercial products. First, it was Google Glass (for the not so technophiles here, glass is a wearable computer with a smartphone-like display that lets users text, browse the Web, take photos and run other apps, all hands free), now Google-owned Motorola Mobility appears to be aiming a few inches lower, working on a temporary electronic tattoo that would stick to the user’s throat. In other words, they has come up with an electronic tattoo that lets you communicate with your smartphone, gaming devices, tablets or any wearable tech. The idea is that wearer can communicate with their devices via voice commands without having to wear an earpiece or the Glass headset. Instead of actually speaking to Apple’s Siri or Google Now, you could merely think your voice command.


But hold on for a minute, as there is a bit more to the whole concept than might first appear. The tattoo they have in mind is actually one that will be emblazoned over your vocal cords to intercept subtle voice commands — perhaps even subvocal commands, or even the fully internal whisperings that fail to pluck the vocal cords when not given full cerebral approval. They have applied for a patent for this new technology, so we might just have to do all this Google style. If its good or bad, I’ll let you decide. The patent even states, “the electronic tattoo can also be applied to an animal as well.” I still can’t figure out what Google has in mind.


In images attached to the patent filing, the size of the tattoo appears to be between a postage stamp and a Band-Aid. Other possible uses include making both incoming and outgoing audio clearer. That could mean anything from making smartphone conversations clearer in a crowded room to being able to listen to music without earphones. Still, whether the e-tattoo becomes a reality for any consumer to buy is yet to be seen.

Wristify: Thermal Comfort Reimagined


If you live in a normal household chances are that there is constantly some bickering going on about the house being too cold or too hot. Now, thanks to an ingenious bracelet invented by the students from Cambridge based Massachusetts Institute of Technology (MIT), every household member can regulate his/her own body temperature and be perfectly comfortable.


Wristify is a thermoelectric bracelet that regulates the wearer’s body temperature by sporadically blasting his or her wrist with hot or cold pulses.  Thermoelectric cooling is governed by the Peltier effect, which describes heating or cooling caused by electric current flowing across a junction of two different conductors. Basically, as current traverses these junctions, one side heats up while the other side cools down. If you have a series of these junctions, and put a heatsink on the hot side, you can create a very effective heat pump.

Peltier coolers aren’t efficient, but they do have the advantage of having no moving parts or circulating fluids. All you need is a Peltier heating/cooling element, a heatsink, and a battery. Throw in a wrist strap, and that’s exactly what the Wristify is. In India, where hot weather regularly causes huge, cascading blackouts, the power grid is so stressed that it couldn’t possibly accommodate more air conditioning. Wristify could significantly improve the quality of life for these people.


Bionic Hands – A Different Feeling

Bionic Hands

I think this is going to be one of those breakthroughs in technology that can touch the hearts of millions, bringing tears of happiness to ones eyes. The world’s first bionic hand with the sense of touch is here. A team of researchers from Case Western University have made new prosthetic bionic hand, designed to be capable of using measurements from 20 sensor points to control ones grip. Amazingly, the sensor data is linked directly to the sensory nerves in the patient’s forearm. The control for the grip is then extracted myoelectrically and returned to the muscles in the forearm. “Our dream is to have Luke Skywalker getting back his hand with normal function,” researcher Silvestro Micera told TechNewsDaily, referencing the hero in “Star Wars” who gets an artificial hand after his real one is cut off.

The Amputee

This is the first time that such a variant of the bionic hand will be implanted into an amputee with high hopes that he will regain his sense of touch. The patient is scheduled to wear the bionic hand for some time over a month to see how his body adapts to the new presence. The results of this test is awaited. Everyone is still in high hopes as it is impossible to predict how the body will cope with such a permanent foreign attachment to it. Doctors & researchers say that if all goes well, fully working models would be available clinically in the next two years.

An answered prayer. A dream come true for many.

It can even have next generation applications.



Small is the new BIG!

Get inspired!


Many of us start off with big intentions to do big things. Although I’m a person who loves to dream big, (when I say big, I mean BIG!) I find that there is a power in thinking small when getting started with something. Whenever you’re on the tracks to get anything done, big or small, start from where you presently are. Imagine planning a trip from Trivandrum to Goa and putting your starting point in your GPS as Bengaluru. Things just wouldn’t work out.

We aren’t even close to being perfect, nor do we live in a perfect world, so reaching halfway through 2013 wouldn’t necessarily mean we’re halfway through in achieving our goals. We all wonder what exactly is standing in our way? I would argue that the greatest problem that’s been preventing you from accomplishing your biggest goals is that you’re not thinking small enough.

Yes, you…

What next after Graphene? Stanene!

Topical Insulator

It was fairly recently that scientists called Graphene as the new wonder material, not soon after, it’s time to give way for the new kid on the block – Stanene. According to a team of physicists led by the SLAC National Accelerator Laboratory and Stanford University. a single layer of tin atoms could be the world’s first material to conduct electricity with 100% efficiency at the temperatures up to 100 degrees. It’s true, but the sad part is that, it still works only in theory.

Stanene Lattice

Stanene Lattice

Stanene is a wonder material that is known as a ‘topological insulator’, which simply means its interior is an insulator yet conducts electrons along its surface. By making the material only a single atom thick, the stanene is essentially just a surface, allowing it to conduct electricity with 100% efficiency. The most advantageous factor is that temperatures up to 100 degrees Celsius is the operating temperatures of all computer chips. Stanene could well be the Silicon replacement we were looking for. But I should remind you, this still works only in theory, the final product is yet to be fabricated.

Next Generation

Shoucheng Zhang, a physics professor at Stanford and the Stanford Institute for Materials and Energy Sciences, said, “Eventually, we can imagine stanene being used for many more circuit structures, including replacing silicon in the hearts of transistors. It could increase the speed and lower the power needs of future generations of computer chips, if our prediction is confirmed by experiments that are underway in several laboratories around the world.”

Perceptual Computing


The first true touchscreen was unveiled in 1974, and the resistive touchscreen was patented in 1977 and is still used today (although capacitive touchscreens have taken over now). It’s been close to four decades, don’t you think it’s time for an upgrade? First it was Leap Motion that caused a stir in the industry, but it didn’t rise to expected levels. Now, Intel has joined the league, and when Intel plays the game, they dominate. Perceptual computing—the next big wave of technology—is about to hit, bringing with it the promise of very engaging computing experiences.


Perceptual Computing (PerC) is an organization within Intel Corporation which focuses on next-generation, natural user interfaces such as touch, gesture, voice, emotion sensing, biometrics, and image recognition. The organization is funded by a $100 million grant from Intel Capital. Intel have provided developers with their own Intel Perceptual Computing SDK. Developers are now working to make computers as cognitive about their surroundings as we are  so they can process much of the information around them and arrive at a logical conclusion based on a user’s intent. Extracting information from the environment will include data points such as the directionality of the voice (for example, is the user talking to the computer or to a friend nearby?), the ambient background noise, facial recognition for automatic user selection (and security), 3D maps of the environment for object and gesture recognition, and more.


Intel had demonstrated how it would work. Cameras sensed the position of fingers, and spun virtual lightning between them. A user’s hands could be used to tickle a virtual child. And in another demo, Eden played the game Portal 2 by waving his hands and orally commanding the computer to drop a Companion Cube. Finally, Eden demonstrated a new version of the Nuance virtual assistant, co-developed by Intel and Nuance and running on top of Intel’s Atom and Core silicon.


Intel has been the biggest player in terms of technology and innovation in the industry. Whether this will be the future of computing, we will find out. Soon.
