Screen Recording: Ubuntu


I have used CamStudio in Windows, and I am happy with it but, there are times when we have to make the most of what is available.This time, I needed to record screen-cast in Ubuntu.

# add-apt-repository ppa:maarten-baert/simplescreenrecorder
# apt update
# apt install simplescreenrecorder

Despite of being simple, it has all essential features of CamStudio for Windows or QuickTime for macOS, and it recorded very good quality of audio and video! Making itself my new favorite screen recording application.

Earlier, I tried using VLC for screen capturing, because it helps me to avoid yet another software program on my computer on my computer and, VLC also lets me choose file formats to save my recording to.

Here are the steps:

Getting Started: Python


I personally think that Visual Studio is the best IDE, and I spend most of my day in it. And I’d definitely by using Visual Studio as much as I can –  if you are on Windows, Visual Studio’s Python support is worth exploring.

I’d leave the choice up to you. Both IDE have free and paid options.

I think Visual Studio is an engineering marvel. If as much effort went into space travel as went into the design of this, we’d be on Mars by now.

What is the 2038 problem?


The Year 2000 problem is understood by most people these days because of the large amount of media attention it received.

Most programs written in the C programming language are relatively immune to the Y2K problem, but suffer instead from the Year 2038 problem. This problem arises because most C programs use a library of routines called the standard time library . This library establishes a standard 4-byte format for the storage of time values, and also provides a number of functions for converting, displaying and calculating time values. Continue reading →

My Publications

  1. Introduction To Linux ( Download )
  2. Unix – Linux Command Line manual ( Download )

To, The Reader

The main reason for preparing such a handy book is to give, to the point and specific guide to the reader. I’ve searched a lot for such a manual when I was creating my own live operating system: “Linux Spark” but every time I read from any resource I found either something missing or something too technical. This book will help you, whether you are an experienced guy, Administrator, newbie or just a student finding some quick reference manual with its lucid and simple language. This book is ready for you to go to the terminal and just start commanding your UNIX/Linux system !

Your suggestions, comments and guidance are gladly accepted. It’s my strong wish that you share this book with more and more people who are really interested, because I firmly believe that the knowledge is free and to get some definitive guide exactly when you need … Should feel like magic!
