3 Mistakes to be avoided by 2012 passouts



The year 2012 has been famous than any other year for the big reason of being considered as the end of the world.
Well, that’s not the only annoying thing about the year 2012. Students who have graduated have more reasons to complain about this year because of the economic state of the world & low placements across the industry.
When the whole world is suffering from economic slow down & job cuts , there is nothing that a 2012 pass out can do than cursing the year again
But you can avoid making some common mistakes and save your time & energy.
  1. Don’t go & join a course just because you have some free time.
  2. Undermining the importance of Aptitude & communication skills
  3. Don’t think of back door jobs, no matter how much money you have
    • 1) Don’t go & join a course just because you have some free time.
Time & Again in all the posts I write, I just talk about this thing. When there is no company which recruits freshers asking for some specific skill set, I wonder why people line up & go for classes.
Mostly it is Java & .net which are famous courses took by the job aspirants, but these are technologies used to build Enterprise software systems running on multiple servers with distributed architecture.
So no small company (well very few does) would handle Java & .Net projects and big companies do not take freshers with specific knowledge, they just ask for freshers.
This all being said, I don’t discourage people who try to learn , all I am trying to convey is that don’t just learn some thing because that you get a placement, instead learn if it is your passion & if you can solve(Implementation) even a smallest of the small problem using that technology.
Consider other alternative technologies before deciding upon learning like PHP, Ruby on Rails etc where there is huge demand in startup’s & mid size companies.
  • Undermining the importance of Aptitude & communication skills
While many job aspirants spend a lot of their time preparing technical skills, many do undermine the need for Aptitude or communication skills. The need for analytical/problem solving skills is high in the industry than the technology.
I would put it this way, “Technologies may change over a period of time & it is the analytical/problem skills which are required to solve any problem you face irrespective of the technology”.
So start trying to improve your problem solving skills & analytical skills, you can solve sudoku , puzzles , rubik/magic cube etc to start with. Try to inculcate Out of box thinking rather than the conventional thinking. At times your idea may look crazy, but yeah you have to be crazy at times
Apart from this, you should be able to communicate your idea & this is considered as essential skill.
I often meet people who keep on learning on technology for months and when the opportunity knocks itself they end up failing in the Aptitude or group discussion & they end up not being considered for the Technical Interview. See how sad is all these?
Don’t regret later, make a plan & prepare.
  • Don’t think of back door jobs, no matter how much money you have.
I also get queries about back door jobs & if you ask me I would say back door jobs as myth.
Some people are ready to pay any amount of money what ever it takes to get em a job, but they end up sitting in home for years.
Human resources are the key to any organization and so no company would make any kind of provision to let people enter just because that they have money.
If you know some one who entered like that, then you have seen one of the luckiest people in the world & guess what it is difficult for him to sustain.
So to make it simple, work hard with a great plan & who would stop from getting success.
All the very best for your future endeavors & drop in your comments about the article or if you have any queries.

ARTIFICIAL LEAF TO PRODUCE FUEL FROM SUNLIGHT…?



Two teams of researchers in the US have taken important steps towards the creation of commercially viable”artificial leaf”– a hypothetical device that can turn sunlight into electrical energy or fuel by mimicking some aspects of photosynthesis.
Earlier this year, the chemist Daniel Nocera at the Massachusetts Institute of Technology (MIT) announced artificial-leaf prototypes.
Now, working with two different teams of researchers, he has published two papers on different devices that represent progress towards effective and commercially viable versions of the artificial leaf.
Both teams made their devices from silicon wafers that are coated with catalytic metals and protective layers.
The prototype solar cells are about the size of a credit card and can capture
sunlight and then use the energy to split water into its constituent oxygen and hydrogen.
This is different to conventional photovoltaic cells, which convert light directly into electricity.
With these new devices, the ultimate plan is to recombine the two gases in an integrated fuel cell, thus converting the chemical energy to electrical energy.
Producing fuel rather than electricity has the advantage that the fuel can be easily stored until it is needed.
Both artificial leaves use a silicon n–p junction: a bilayer of n-type and p- type silicon. An incident photon is absorbed to create an electron–hole pair in the semiconductor. The electrons migrate to the n-side and the holes to the p-side.
The holes then drive the splitting of water in a process mediated by the outermost layer of the cell, which is a photocatalyst.

Legs- The Organs of your body



Keep Walking…..
The Organs of your body have their sensory touches at the bottom of your foot, if you massage these points you will find relief from aches and pains as you can see the heart is on the left foot. Typically they are shown as points and arrows to show which organ it connects to.
It is indeed correct since the nerves connected to these organs terminate here.
This is covered in great details in Acupressure studies or textbooks.
God created our body so well that he thought of even this. He made us walk so that we will always be pressing these pressure points and thus keeping these organs activated at all times…!!

A City that rely entirely on solar energy and other renewable energy sources.



A city is currently being built in dubai that will rely entirely on solar energy and other renewable energy sources.
It’s called Masdar City, and is currently a project in Abu Dhabi. It’s a planned city currently being built by the Abu Dhabi Future Energy Company, with governmental aid. The city, which is designed by Foster and Partners, is going to rely completely on solar energy and other renew
able energy sources AND have a sustainable, zero-carbon, zero-waste ecology. Sounds pretty ambitious, don’t you think?
Masdar City will also be the headquarters of the International Renewable Energy Agency, an organization whose name is pretty self explanatory. The first tenant of the city moved in back in 2010, which is the Masdar Institute of Science and Technology. Though the city was to be completed by 2016, it was pushed back to 2025. Still, that’s not TOO far off for something so ambitious.

World’s most dangerous bird


Meet the world’s most dangerous bird; the Cassowary!
This bird lives in the rain forests of Australia and New Guinea and is actually pretty shy if undisturbed, but if you get to close and it thinks you’re a threat you could receive a bone-breaking kick or get sliced by its dagger-like sharp claws. The Cassowaries are very unpredictable, aggressive creatures, especially if wounded or cornered. During WWII, soldiers stationed in New Guinea were warned to stay away from these birds, but some of them still became victims.
It is important to note that the Cassowary is on the endangered species list.

INVISIBLE CAR

AMAZING THE INVISIBLE CAR –BENZ
1. Using optical camouflage, technology experts at Mercedez Benz have figured out how to make an entire car disappear.
2. The researchers created the illusion that their new zero emissions F-Cell Mercedes Benz is not even there at all, the Daily Mail reported.
3. Taking the principal that to see through something you need to see what’s behind it, they covered the driver’s side of the car in mats of LEDs, and mounted a digital SLR camera on the opposite side of the vehicle.
4. The camera shoots video on the passenger side of the car and the video is displayed in real time on the driver side of the automobile.
5. This ingenious approach, originally pioneered by scientists at the University of Tokyo, works on the same principles of the blue screen used by TV weather forecasters and Hollywood filmmakers

Plastic Blood becomes a lifesaver

Researchers in London announced plastic blood, their latest breakthrough, may turn out to be a life saver.
It’s not the kind of plastic that you usually think. It’s not like a plastic bowl or something. It’s a polymer, which means it’s a large molecule.While engineers are currently using plastics for everything from light transport vehicles to solar panels, it’s the idea of plastic blood that has particularly set researchers’ hearts racing.
Especially in situations of emergency,this could be a breakthrough, as it can be administered to anyone irrespective of blood type. But this will take another decade to fructify.
” It’s the Holy Grail in science and medicine to mimic blood. We’re at the very beginning of this. So, each step of the way we should get betterat it ,” said Lance Twyman of University of Sheffield.
For now, it remains on display at the Science Museum in London alongside other breakthroughs in plastic, whichcover the last 100 years of the man-made material.

Worlds Smallest Petrol Engine

Scientists have created the smallest petrol engine in the world (less than a centimeter long not even half an inch),small enough to power a watch or any small gadget.The mini-motor which runs for two years on a single squirt of lighter fuel is set to revolutionize technology associated with it. It generates 700 times more energy than a conventional battery. It could be used to operate laptops and mobile phones for months doing away with the need for charging.
Experts believe it could be phasing out batteries in such items within just six years. The engine, minute enough to be balanced on a fingertip, has been produced by engineers at the University of Birmingham. At present, charging an ordinary battery to deliver one unit of energy involves putting 2,000 units into it. The little engine, because energy is produced locally, is far more effective.
One of the main problems faced by engineers who have tried to produce micro motors in the past has been the levels of heat produced. The engines got so hot they burned themselves out and could not be re-used. The Birmingham team overcame this by using heat-resistant materials such as ceramic and silicon carbide.

India

The official Sanskrit name for India is Bharat.
INDIA has been called Bharat even in Satya yuga ( Golden Age )

Proud to be Indian !

Auras, “the real MYSTERIES”



WHAT IS THE AURA ?



The aura is the electromagnetic field that surrounds the human body (Human Energy Field-HEF) and every organism and object in the Universe.The Human Energy Field as a collection of electro – magnetic energies of varying densities that permeate through and emit or exit from the physical body of  a living  person. These particles of energy are suspended around the healthy  human body in an oval shaped field. This “auric egg” emits out from the body approximately 2-3 feet (1 metre on average) on all sides. It extends above the head and below the feet into the ground.

WHAT DOES AN AURA CONSIST OF?

The aura consist of seven levels/layers/auric bodies . Each one of the subtle bodies that exist around the physical body, has its own unique frequency. They are interrelated, and affect one another and the person’s feelings, emotions, thinking, behaviour, and health as well. Therefore a state of imbalance in one of the bodies leads to a state of imbalance in the others.  
Some aura colors and their meaning are:
“Silver:  Intelligence
Ruby Red:  Vitality
Violet:   gentleness
Rose Pink:  Love
Sapphire Blue:   Healing, spirituality
Gray:   Illness, fear
Brown:   Cruelty Stubbornness”
— From the book Healing Powers Of your Aura by Barbara Martin
There are some great websites that can help you see auras and understand their meanings, hear are some of them.
http://www.thiaoouba.com/seeau.htm
http://www.reiki-for-holistic-health.com…
http://www.worldtrans.org/spir/aura.html

The Mystery:

The one thing that connects every new-age guru from numerologists to palm readers is that they all think that auras are a thing. And why not? We have photographs of them.
Generally speaking, auras are, you know, the manifestation of universal energy that, like, surrounds us all, man. And for a fee, professional aura readers who butcher the Papyrus font can take a look at your aura and tell you exactly what your spiritual malaise is based upon their handy color chart.

“I see sadness, and also that you need to replace your camera lens.”
Those aura photographs can be taken with a kind of device that runs a current through your body. Not strong enough to kill you usually, just enough to bring out that spiritual energy. And for years, scientists didn’t know what the hell it was. Maybe it was magic.

The Solution:

Turns out it’s regular, old-fashioned sweat.
The electrical photographic method actually just brings out the outline of whatever it’s observing in a beautiful neon glow. In the case of human beings, it also captures the cloud of sweat floating around the filthy, filthy hippie in question. The effect is much more dramatic if the subject is keen and nervous about, well, having an electric current shot through his body.

“Huh. Looks like you’re feeling very apple today.”
But there are some other explanations for why auras have featured prominently in iconography even before this neat camera trick.Visions of Auras can be caused by defects in your own eye, brought to you by medical conditions such as migraines, epilepsy and eye burns. This is something even aura believers admit.
It also works if you rub your eyes really hard for about four minutes.
Still, there’s something to be taken home from all this — if you’re into that sort of thing, you now have a way to know exactly what color your sweat is.
