Robots

We are surrounded by various kinds of technology, and one of the most commonly encountered technology is a robot. Ever wondered, how the traffic lights keep on switching themselves from time to time without getting tired ? They are a robot, that has been assigned a task, which it keeps on performing without asking any questions.  Similarly, a vehicle follows whatever the driver instructs it to, without asking any questions. These simple robots can be made smarter by something called artificial intelligence, but it still is just another algorithm that makes use of heuristics to determine what would be the optimal choice. Google Allo’s smart reply would be a very common example of what artificial intelligence is like.

In most simplistic sense, a robot is referred to something that can do a particular piece of work repeatedly, without getting tired. A robot does “forced labor” in some sense. It is like a slave, that cannot decide anything on it’s own. The latest developments suggest that we might be able to create a simulated brain, that could impersonate a human (commonly called androids), though presently a robot is far from such capabilities. An old but quite interesting experiment of this kind of cognitive science was the Medusoid, an artificial jellyfish. This was an attempt to replicate the heart movements, using silicone and rat heart cells, but the success it received was tremendous, in the fact that it could replicate a jellyfish.

The creation of robot’s has been a revolutionary idea. It has transformed innumerable fields. It has facilitated doing computationally intensive work, without much wastage of human resources. For example calculation tasks can be easily given to a robot, like calculations for a house construction, calculating the most efficient wing design to minimize the air resistance, calculating shortest path to reach a destination. Even some tasks that are hazardous to humans, but yet essential can be handled by a robot. Not only calculations, but surveillance tasks can also be done very effectively with the use of robots. The robots have transformed the world, and have been an integral part of the IT revolution. They are slowly taking up a large portion of the industry level tasks. The future where every person will have their own personal robot assistant isn’t far away.

Cyber Security

We work with internet everyday. It has become an essential part in our life. We cannot imagine a day without it. It is such a vital tool for so many purposes. There are lots of things on the net, that are now accessible to even a common person. So much information, that it is impossible for one person to know everything. This simply means that we require instructions about how to use a facility available to us on the internet.

Hackathons – A great way to learn

I was introduced to the term Hackathons in my first month of my college. The software development society of our college (called BYLD) organised a hackathon. What I came to know was that hackathons are an event for learning. They aren’t actually about hacking. The name is a bit misleading. We actually work on making something productive and not particularly hack anything. This was my incentive to participate – I’d get to learn. Since then I have participated in two hackathons in my first 3 months, and both of them were an exhilarating experience of learning. I learned a variety of skills. Not only related to the hackathon’s theme, but also non-transferable skills that include learning how to use a particular piece of library, how to collaborate with others and team work etc.

Frameworks

In any device, plugins are an indispensable tool for customization. For e.g in a television, we can add a home theater, to enhance our experience. In any book that we read, we can add a bookmark to help us remember the last page, but it isn’t necessary. Similarly in programming a real world problem, we have several small tasks. Some of these tasks are routine one’s and have an already written piece of code, that we can reuse in our work. This is called a Library.

Internet of Facts

Recently I received several fake fact messages, and what was more interesting is the people forwarding these messages were highly educated. Today it is not uncommon to receive messages that say If we do not forward it then a decade of bad luck, or we wont ever live happily, or maybe even we’d get murdered that midnight itself by a ghost. After some thought, I realised that such things were extremely uncommon before the advent of the internet. Before the Internet existed, people relied on written sources of information. They used to read newspapers for information. Books and journals were published to demonstrate a point. These used to take effort and time to make, and rarely contained false information, because hardly anyone would take so much pain and effort to spread false messages.

Wireless World – A wonder

A long time back, when phones, were introduced, they had a manual pad and pre-programmed functions which limited their usage (only calling). At that time we didn’t even considered that making a phone controllable, and that too with a touch would be possible (and even if possible, then not feasible). Today we use smartphones and hardly see any of the primitive, only calling design phones, and control them by a touch.

QR Codes – Omnipresent

I am amused at how the world has been revolutionized by technology. Recently in my nearby supermarket, I saw a simple placard having a QR code powered by something called Paytm (it’s an acronym of Pay Through Mobile). This placard, was not only in that shop, I could see it on the cabs, petrol pumps and even in the parkings at a few places. The technology that this little placard uses is the QR code. What is more ironical is that this QR code was used by Japanese automobile companies to identify their machine parts, and now these codes are used for identifying humans – yes, you will find this code on the visiting Cards of people and even on their T-Shirts.
