    When you see (a + b)2 what is the first thought that comes to your mind. Mostly the expansion a2 +b2 + 2ab. What is a2 +b2 + 2ab? Simple way to think is (a+b)x(a+b). You see everything is multiplying with everything and producing all kinds of combination. There is the purest form of “a”,…

    You start reading AI. Then you realize- hold, go back to probability. You start probability; hit binomial, law of Central Theorum, the Gaussian. The Gaussian first look like a triangle and then like an expanding and shrinking wave. Wow, I know this wave… it looks exactly like the chart of a stock. The Bolinger Band…

    In the schools days, for me, equations with equals itself were so hard to think. 2x + 5 = 0. Wow somebody got mad. 2 and 5 are already greater than 0 and then this equation. No wonder my mind never reached inquality equations. But when I see at an inequality equation like y <…

    y = mx + hwhat does this equation represent. A line? Think again. It gives you only one output, one point on graph. How come it gives you a line….This simple equation is a world in itself. m – the coefficient (slope, rate of change, correlation), x- the variable (the input data, the independent variable)…

    I realize algebra is key to the way Machines learn. And the most basic component of algebra is a Line. In crudent understanding, a line is something that connects two points. But this simple concept when seen in context of regression, it becomes the base of prediction. The following algebric equation builds a line with…

    It may not look coherent to write on magnet after writing on software architecture and the advent of microservices and virtualization. But there is always an urge to go back to the basics. There are subject in your backyard which you read, cleared the exam but could not grasp it. Recently I was reading BSS-OSS…

    Application security is something you can’t escape in the connected world. I have created a YouTube channel which deals with the understanding the concepts of one-way and two-way SSL and how to set it. The first video is more to do with concepts, building the certificate store (keystore and truststore) and ensuring if they are…
