Why at least once you should travel in an overcrowded train in Kerala.

             Hey folks! It's been a long time since I put my pen to paper or my fingers to my keyboard(PS:I meant blogging). Well technically I use my fingers for loads of things let alone a keyboard. I wasn't quite fond of the concept of blogging but of late, I'm finding a weird affection for it. So today I found the right subject for a blog post.
            I happened to attend a conference of Free Software Professionals at the Mascot Hotel in Thiruvanathapuram. After the conference finished, we all were heading back to our homes. After Googling I found that the distance separating Kottayam and Trivandrum was a whooping 127 kilometers. So obviously, we had to find a public commuting service. After planning with my friends, we decided to go adventurous. We planned to book a second class Indian railway ticket on a Sunday(PS:That's one of the most adventurous traveling options in India). For my overseas viewers, this is what it looks like.
  We went to the railway station and bought our tickets. Our train was supposedly arriving on Platform 4. We went there and were waiting for our train to arrive. We had a Pepsi and a burger each to kill time. After eating and listening to a couple of Chainsmokers' songs, the train arrived. There were a lot of Bengalis with us to board the train.(Since 10% of Kerala's population now has Bengalis, it is evident.) When the train arrived, the bengalis were running to the coach as if they were getting  free sweets on Durga Pooja. They outclassed the speed of Usian Bolt, and booked all there seats on the entire coach so we had to wait for another 45 minutes for the next train. The bengalis were dancing and removing there vests as if they were in Miami. The train departed and the next train arrived. We luckily boarded it. The scene resembled like the one we can see in the picture. The people were pushing each other like Trump wants to do with the Mexicans. It was a Game of Thrones fight scene! So we all had to unleash our inner Jon Snows. After the train departed from the station, the level of oxygen had reduced drastically. It was Bengali stink and perspiration everywhere on the coach. The scene resembled when Jon Snow was suffocated during the Battle of Bastards. Somehow, I told myself to fight this and deal with this. My inner self control powered by Paulo Coelho and Robin Sharma were put into effect and managed to appreciate the beauty and luxury of the travel. Can we hear "Hey nigga, that's my seat" "You went to take a shit, I captured it" conversations ever in an airplane? Never right. There lies the beauty of this journey.
      Since Bengalis are the third world creatures in Kerala, they can be found anywhere like Indians can be found anywhere around the globe. The Bengalis occupied whatever they possibly could in the train. They sat near the toilet probably listening to Mamata Banerjee's speech while another takes a shite at the toilet. They were laughing and playing while the smell was badly contaminating the entire coach. While everyone else were grossed out, they weren't. That's the spirit.
This is Sparta!

The above picture shows some of the adventures of Bengalis in Kerala.

So yeah, the journey continued. Some 40-50 people more entered the coach seriously disrupting the center of mass. But still, the train continued it's journey. We were dislocated and lost ourselves on the train. We called each other and informed our location. Mind you, even Google Maps couldn't trace it. There wasn't even a millimeter of space to move any part of my body. I was the Internet Explorer while updating a New Year post on Facebook. So we were stuck beneath the 'perspirational' and shite environment travelling a distance of 127 kilometers at the rate of 40km/hr. After 6 long hours, we reached Kottayam and boy we were bowled. Bengalis came and beat everyone else like Athletico de Kolkata came and beat Blasters. At the end of my last few lines, I just pose a simple question to all of you. Why go on Bungee jumping, a rally or off road biking along the high ranges when you have many greater adventures to face. Face bengalis in Kerala, the results will leave you speechless. Beware of Bengalis. They can replace Mohanlal and Sreesanth one day. The latter doesn't really matter that much. This blog is intended sarcasm so Mamata Banerjee, please leave me alone.

Take a sneak peek of how robots have been used in space.

Since the launch of the first satellite Sputnik 1 in 1957, robots have been used used to explore space. These Early space machines, although cutting-edge at the time, were mainly remote-controlled and had little to no autonomy. Today's robots are very different to these early machines, computing power and circuit miniaturization has allowed designers to create robots capable of doing useful tasks in space that previously we could only have imagined doing. 
    The following sections present a number of important space missions and show how robotics is being used. 


Robonaut2 (Robot Astronaut)

Robonaut2, or R2 for short, is the next generation dexterous robot, developed through a Space Act Agreement by NASA and General Motors. It is faster, more dexterous and more technologically advanced than its predecessors and able to use its hands to do work beyond the scope of previously introduced humanoid robots. 

Robonaut2 surpasses previous dexterous humanoid robots in strength, yet it is safe enough to work side-by-side with humans. It is able to lift, not just hold, this 20-pound weight (about four times heavier than what other dexterous robots can handle) both near and away from its body. 

The following video shows the latest development in space robotics; the humanoid robot astronaut (Robonaut) developed by NASA and GM:

The idea of using dexterous, human-like robots capable of using their hands to do intricate work is not new to the aerospace industry. The original Robonaut, a humanoid robot designed for space travel, was built by the software, robotics and simulation division at Johnson in a

collaborative effort with the Defense Advanced Research Project Agency 10 years ago. During the past decade, NASA gained significant expertise in building robotic technologies for space applications. These capabilities will help NASA launch a bold new era of space exploration. 

"Our challenge today is to build machines that can help humans work and explore in space," said Mike Coats, Johnson's center director. "Working side by side with humans, or going where the risks are too great for people, machines like Robonaut will expand our capability for construction and discovery." (http://robonaut.jsc.nasa.gov/).



Mars Exploration Rover Mission

NASA's Mars Exploration Rover Mission (MER), is an ongoing robotic space mission involving two rovers, Spirit and Opportunity, exploring the planet Mars. It began in 2003 with the sending of the two rovers — MER-A Spirit and MER-B Opportunity — to explore the Martian surface and geology. The Mars Rover Spirit landed on the Martian surface on the 4th January 2004 and Opportunity on the 25th January 2004, since then the rovers have continually send back data about the red planet.

On May 1, 2009 (5 years, 3 months, 27 Earth days after landing; 21.6 times the planned mission duration), the Rover Spirit became stuck in soft soil and after months of trying to manoeuvre free of the hazard, Scientists decided to turn the Rover into a stationary observation platform.

surface of Mars. Two rovers have been built for 2003
launches and January 2004 arrival at two sites on Mars.
Each rover has the mobility and toolkit to function as a
robotic geologist.


Each rover is made up of a panoramic camera at human-eye height, and a miniature thermal emission spectrometer, with infrared vision, which help scientists identify the most interesting rocks. The rovers can watch for hazards in their way and manoeuvre around them. Each six-wheeled robot has a deck of solar panels, about the size of a kitchen table, for power. The rover drives to the selected rock and extends an arm with tools on the end. Then, a microscopic imager, like a geologist's hand lens, gives a close-up view of the rock's texture. Two spectrometers identify the composition of the rock. The fourth tool substitutes for a geologist's hammer. It exposes the fresh interior of a rock by scraping away the weathered surface layer. 

The Mars Exploration Rover mission seeks to determine the history of climate and water at sites on Mars where conditions may once have been favourable to life. Each rover is equipped with a suite of science instruments that will be used to read the geologic record at each site, to investigate what role water played there, and to determine how suitable the conditions would have been for life.

Basic trick that can be used at school/college computer labs.

So folks, today I'll be teaching you all a very basic trick that you can try on your school/college lab computers. Well, most of the geeks might know this trick but this page is dedicated to the people who are looking to create a pain in the neck of their dumb teachers/lecturers but just are too dumb themselves to rather go to YouTube and check it out. Anyways, you have entered the right place. You'll learn much groovier shit in the next intervals of time. So yeah, where was I? The trick, right. So, there is thing called a cursor where can you move it to whichever pixel you want on the available screen.A cursor is also called a mouse(PS:For the dumb ones). The cursor can be moved anywhere within the given pixel capacity of your computer/laptop screen. So let's assume you have a Windows OS(Spoiler Alert:Else this shit won't work), so there is a start icon on the bottom-left hand corner of your screen. Click it using your fingers/finger(It doesn't matter), then click Notepad. After clicking notepad type exactly like shown below;
"shutdown t-30s trojan virus detected\c" 
This tricks the computer that a Trojan virus is detected and commands it to shutdown after 30 seconds of time. You save the shit...Kaboom....Each and every time the computer restarts after 30  seconds. There is also an alternate way of doing this:
Right-click your cursor, move the cursor to "New", click "Shortcut", type the shit shown in bold italics above, personalize your icon(My Computer, Internet Explorer etc) and this trick works again.
If you were too dumb to try on your own computers, then buy a new PC. I was messing with you. So just type this shit, it will be all fine:
"shutdown t-30s trojan virus detected-a"\c"
Here "a" stands for abort.
I was typing super swift, so some mistakes might have crept out. I'm always cool with feedback. And for those who still couldn't grasp the aforementioned trick, please subscribe to my YouTube channel, I'll personally take the trouble to upload a video of the same. And for my geek and nerdy and knowledge craving friends and others....I'll come next time with some interesting stuff that will keep you....well..interested. Just to provide an insight of my blog, my blog will provide sarcastic articles, codes, virus creation, hacking tips, cloud computing, encryption science and much more groovy stuff without using heavy, posh syllable words so people having a basic understanding of English can read my blog. So Adios for now and thanks for bothering.
