Sci-fi Sunday--PLURALITY







This Sci-fi Sunday we would love to take you towards another side of this world, maybe to occur in the next decade, where everything senses you. Yes we are talking about computational grids that detect your DNA and thus the unique you. This allows the authorities to access your location/activity anytime. You might be thinking that your privacy will be breached then. But did you ever thought what if your DNA gets cloned?


Have a look at PLURALITY, then.

IceLake

Moore’s Law; the number of transistors in any Integrated circuit doubles every two years.

Have you ever wondered, how the size of a computer is getting smaller, processes becoming faster and swifter?


Numbers have always been a fantasizing fact for many of us. Talking about the numbers in the most lucid way, while discussing the electronics say, how many gates are used to make a flip flop, or how many transistors itself are used for making a AND gate. 
The transistors are the building blocks of a CPU and digital circuits. We need to shrink the size of transistors so that we can increase their count in the same unit area.
There we go, we have come down to 10nm technology, which has become a mere commercial name for the different manufacturers.
The fabrication technology is actually what the ‘nm’ numbers show but that also has a thing of the past now, as we have so many competitors in the market- Intel, Ryzen, Samsung etc. 

Bringing to you, the brief on Ice Lake, by the courtesy of Intel


What Intel’s 10nm brings is even better than the 7nm offerings of Samsung and TSMC.

What is Storage Capacity? Where do the bits go?
All the technology that we see around us will saturate to a point in time if the hardware is not upgraded, that is why we have so many options available for the ICs and giving it directly to you; processors

Let's go back to where it all started, ENIAC, the full room sized computer which was used for the basic calculation that too in a very conventional methods.
Look where we have reached now, GigaHertz ! The processors nowadays have the clock frequency in the GHz range. 

The Intel Icelake comes with a strong specification of having 4 cores, 8 threads, and operate at 4.1GHz in turbo boost mode.

The 14nm technology which was prevalent in the Intel's previous designs- Cannon Lake, had a number around 100 for the transistor density.

There is something known as Transistor Density, which is calculated in terms of MTr/mm² which stands for millions of transistors per square millimeter. 

How much you can fit into a small chip, that is the race!

Ice Lake isn’t the first time Intel has deployed its 10nm transistors. The very first batch was actually released under the Cannon Lake architecture in extremely limited quantities.


Is this the final trend?
No, Physicists have already started to call out for the collapse of Moore’s law!

According to Kaku, a theoretical Physicist:
"In about ten years or so, we will see the collapse of Moore's law. In fact all ready we see a slowing down of Moore's law. Computer power simply cannot maintain its rapid exponential rise using standard silicon technology". 

Intel Corporation has nodded for the same. Kaku adds when Moore’s law will collapse in the upcoming decade, then we will have to go to the molecular computers and thus finally to quantum computers.

Then, What’s next?
TIll the time, Moore’s law is valid, our very own known Tech Giants, Intel, AMD, and other chip makers gonna squeeze the last ounce of speed and power they can from the silicon designs.

Merry Christmas


As we celebrate the birth of one of the greatest spiritual masters, may you get His unconditional love and blessings.

May the Christmas tree hold happiness, love, friendship and laughter for you always. 

May Saint Nick bring you prosperity, joy and peace of mind. 

Whole IEEE NITP family wishes you and your loved ones a merry Christmas and excellent year ahead.

This SCI-FI Sunday, SKYWATCH


The world might be ending but who knows there's another just like this one... We just need to go down one dimension.

“It's just a game of perception.”

The sci-fi gives you the perpetual ocean to dive in, unrestricted arena to roam about freely, and to feel the pressure with the depth you encounter, to relive with the fear each time you take a pause and breathe again, and it gives you the lengthened time to see again!

"Are you sure, you are not living in a matrix?"

We might be. The world might be ending but who knows if we can skip all these, all we need to do is to go down one dimension.

Who knows we might be just another toy in those higher dimension creatures’ play-house. Who knows, we might be confusing those mere mortals to be our god.

Now, please don’t be engaged. I am just suggesting a weirdly possible concept. It’s up to you to ponder upon it or dismiss it like all other possibilities.

Never stop a story from being told. Because however strange it may sound, there was a human brain behind it or if you prefer it this way “God was behind every creation”. And he might well be… but do we know him at all.

Science believes in reasons and fiction believes in a story. Well we are here to take you through a very unreasonably “reasonable story”. So, guys buckle up because IEEE NITP brings to you, the insights on a short movie- SKYWATCH.

Amongst the exotic collection of fictions, why SKYWATCH? Well, some of you might be aware of the reasons behind that is this movie a completely rendered movie. CG artists, right; you got it correct!
It took almost six years to film a 10-minutes short movie, which is a hell lot of time, now you know, of all the bestsellers and blockbusters why we started with this.
All thanks to the efforts of Colin Levy that showed us how with just technology we can create something, right from the raw!

Shazam


In this first tech blog we will talk how Shazam app works. Some of you might even don't know what Shazam app is. Imagine you are in the classroom and your teacher has not yet arrived. Suddenly someone starts playing a song and after listening the song for a few seconds you start liking that song but you don't know the name of the song. This is where Shazam comes into play. Shazam records the song for a few seconds and tells the name of the song along with the name of artist and album. Now in coding we know that this can be done by comparing all the songs in Shazam's database with the recorded song. But it will take a lot of computation time as there are millions of songs in it. So how does Shazam recognises a song within a few seconds?


At first, we need to understand how Shazastores songs in its database. Firstly it converts the song into its spectrogram. Spectrogram is a 3-D graph of song with time on the x-axis, frequency on the y-axis and amplitude on the z-axis which is representated by a colour. It looks something like this,





It is then converted to its audio fingerprint which is a 2-D star map extracted from its spectrogram where each star or peak represents the strongest frequency at a particular time. It looks something like this,




After this they create a combinatorial hash for each peak. Hashing function in computer science is a function which takes a varying length of input and produces a fixed length output (in this case 32-bit integer) which is known as hash. Combinatorial hashing involves selecting a peak as an anchor point and a target zone of multiple neighbouring peaks. The anchor pint is paired with each peak in the target zone which produces a time frequency vector. All of these vectors are then inputted in a hash function which creates a unique hash for each song. Each hash is linked to the song name, artist and album.When you open Shazam app and record a song, it instantly creates its audio fingerprint filtering the noise because it only produces data points for stand out frequencies. After this as the process explained above, it creates its unique hash and finds a match very easily.
