Have you ever had the desire to lose your free will? Or, alternatively, have you ever had the desire to take someone's free will? Yes?  You are in for a real treat! We have all seen the magic. And this, like the others, is all science. We can control others arms with our brain. Yes, it's true. We were going to connect two wires on your elbows. And two wires on the other person's elbow. And BOOM. If you move your arm now, the other person will not be able to move his arm according to his own will. Isn't it the coolest brain hack ever? See this video (TED Talk by Greg) to learn more. I know! I have been there. I was thrilled after watching this. You can build this device yourself. Yup, that's true too. All it takes is a simple DIY kit. After All, Greg Gage's aim is to make brain science accessible to all. You can find everything you need to make this device on Backyard Brains , founded by Greg himself. Below is the link to the detailed instru...

We all have watched those silly movies. And, we all have heard about those silly shock therapy given to mental people. Well, I am almost at the edge of getting one of those. Do you know how shock therapy work? It makes current flow through your brain by connecting the ends(positive and negative terminals) of a DC battery to appropriate position in the brain. I am a good person and I want to enhance your language and mathematical ability, attention span, problem-solving, memory, and coordination. And for this purpose I am going to give a shock therapy with hundred times less current than a regular one. This is called tDCS - Transcranial direct current stimulation. What happens when you attach several electrodes to your forehead, connect them via wires to a 'nine-volt battery' and 'resistor', ramp up the current and send an electrical charge directly into your brain? “IT’S like coffee times ten,” raves one enthusiast. “I use it a couple of times a week and problem...

So, you have just finished your supreme-js-learning-pack-for-idiots and coded some nice app and now are on the top of the world. You hail your code as supreme and think that now you have mastered everything. Then you are the right candidate for my quiz, which will test your abilities of dry running the program and knowing the idomatic ES5 (JavaScript) programming paradigms, along with some its usual quirks! :-) (Note: ES6 is not being tested here) JavaScript - easy to learn, hard to master! The quiz is subjective type. You are given a program snippet and are supposed to figure out the output. The program may  have an (intentionally inserted) error, so beware while deciding your answer. Assume that all snippets execute in a browser environment (in the global scope) with "use strict;" mode enabled. Each output has been tested on Chrome mainstream build and made browser independent. If you still feel your browser's console output is different, let me know in the ...

So, you want to make a robot? No doubt that it is one of the fantasies of every child. But, they think that it's tough and they will do such thing when they grow up( I mean go to college or so). Actually, it's very easy.  Anyone, who has a basic understanding of English and maths(grade 5 maths), can easily make a robot of his or her imagination. The most beautiful part of making a robot is that it opens doors to a completely new world, which is full of mind-blowing stuff. It does change your life. Watch this amazing video that list the things, which is centered around a simple device, made by different people. The simple device is called Arduino. If you don't understand most of the things, then you are on right path. By the way, you are going to be a superstar after you understand all this stuff. The Arduino could be an automatic plant-watering control system.It can be a web server. It could even be a quadcopter autopilot. It could be a remote control car. It could ...
