How I met the qutebrowser
It was through the 'windows' of Internet Explorer that I first got a glimpse of the Internet world. During those days, every PC you buy came with a version of Windows XP installed. I doubt if I knew about any other browsers back then ( I don't think I even cared.). A couple of years …
i3- A tiling window manager to declutter your desktop
The corona virus pandemic has forced many governments to enforce a lockdown. This has forced many of us to work from home. Over the last several weeks I have been trying to perfect my home desktop environment to make me as productive as possible and to optimise all the resources I have. At the office …

Rtags completes Emacs
This post is a description of how to setup Rtags on Emacs. The internet is has quite a few resources about Rtags' setup, but despite that I had to go over several of them to get things up and running for me. Rtags is ideally meant to work for C++ projects that use CMake build …
The Curious Case of Preprocessors
What would be the output of the following code snippet: #include <stdio.h> #define V 1 int main() { int Value = 1; #if V == Value printf("Hello world\n"); #endif // V return 0; } If you guessed that the program will print "Hello world" you are wrong. The reason being #if is a preprocessor directive …
The Garden Pi
This is a small project that will introduce you to IoT and on how to use WebIOPi and Raspberry Pi to create a small and cool project. These are the components that you will require for this project: Raspberry Pi B+ ( Any Rpi should work) 3-6V Submersible Mini water pump Wifi Adapter (You can skip …
My Experiments with Boost Graph Library
Recently I picked up "An Introduction to Graph Theory" by Robin J. Wilson. After going through a couple of chapters I felt the sudden urge to try out a few of graph theory problems through programming. To try out the algorithms I first need to create the graphs themselves, which seemed a bit of a …
Range Based For Loops in C++11
Here is a short post on the range based for loops in C++. I recently learned about range based for loops in C++11 standards. These are nothing but easier constructs on writing loops. You no longer have to write: for(initialization;condition;update) The syntax is: for(declaration:expression) Although this looks like a very simple feature there are a few things …
Calling a function On termination of main() in C
Dear readers, A friend of mine taught me this new "trick" where you can call a function when the main() in C exits. In the Library "stdlib.h" there exists a function int atexit(void (*func)(void)) the "func" is any function without any arguments. The atexit() calls the function that you register as soon as the main() …

The World of Dynamic Programming
Recently I came across the an algorithm that can find the maximum sub array in a given 1-D array. Its called the Kadane's algorithm.It comes under the domain of dynamic programming. I would like to write about a few things I understood about Dynamic programing so that it may help someone else to get a …
