Linux is the foundation of thousands of open source operating systems designed to replace Windows and Mac OS. It is free to download and install on any computer. Because it is open source, there are a variety of different versions, or distributions, available developed by different groups. Follow this guide for basic instructions on how to install any version of Linux, as well as specific instructions for some of the most popular ones.  Download the Linux distribution of your choice . If you're new to Linux, consider trying a lightweight and easy to use distribution, such as Ubuntu or Linux Mint. Linux distributions (known as "distros") are typically available for free to download in ISO format. You can find the ISO for the distribution of your choice at the distribution’s website. This format needs to be burned to a CD or USB stick before you can use it to install Linux. This will create a Live CD or Live USB. Try downloading Ubuntu from here  https://ubuntu

Linus Torvalds ,a student at the University of Helsinki started developing Linux to create a system similar to MINIX, a UNIX operating system. In 1991 he released version 0.02; Version 1.0 of the Linux kernel, the core of the operating system, was released in 1994. About the same time, American software developer Richard Stallman and the FSF made efforts to create an open-source UNIX-like operating system called GNU. In contrast to Torvalds, Stallman and the FSF started by creating utilities for the operating system first. These utilities were then added to the Linux kernel to create a complete system called GNU/Linux, or, less precisely, just Linux. Linus Torvalds Richard Stallman Linux grew throughout the 1990s because of the efforts of hobbyist developers. Although Linux is not as user-friendly as the popular Microsoft Windows and Mac OS operating systems, it is an efficient and reliable system that rarely crashes. Combined with Apache, an open-source Web server, Linux accounts fo

Compiling the source code files can be tiring, especially when you have to include several source files and type the compiling command every time you need to compile. Makefiles are the solution to simplify this task. Makefiles are special format files that help build and manage the projects automatically. A Simple Example Let's start off with the following three files, hellomake.c, hellofunc.c, and hellomake.h, which would represent a typical main program, some functional code in a separate file, and an include file, respectively. hellomake.c include int main() { // call a function in another file myPrintHelloMake(); return(0); } hellofunc.c #include   #include   void myPrintHelloMake(void) { printf("Hello makefiles!\n");  return;  } hellomake.h /* example include file */ void myPrintHelloMake(void); Normally, you would compile this collection of code by executing the following command: gcc -o hellomake hellomake.c hellofunc.c -I. This command

What is version control Version control systems are a category of software tools that help a software team manage changes to source code over time. Version control software keeps track of every modification to the code in a special kind of database. If a mistake is made, developers can turn back the clock and compare earlier versions of the code to help fix the mistake while minimizing disruption to all team members. For almost all software projects, the source code is like the crown jewels - a precious asset whose value must be protected. For most software teams, the source code is a repository of the invaluable knowledge and understanding about the problem domain that the developers have collected and refined through careful effort. Version control protects source code from both catastrophe and the casual degradation of human error and unintended consequences. Software developers working in teams are continually writing new source code and changing existing source code. The

What is Git By far, the most widely used modern version control system in the world today is Git. Git is a mature, actively maintained open source project originally developed in 2005 by Linus Torvalds, the famous creator of the Linux operating system kernel. A staggering number of software projects rely on Git for version control, including commercial projects as well as open source. Developers who have worked with Git are well represented in the pool of available software development talent and it works well on a wide range of operating systems and IDEs (Integrated Development Environments). Install Git on Linux Debian / Ubuntu (apt-get) Git packages are available via apt: From your shell, install Git using apt-get: $ sudo apt-get update $ sudo apt-get install git Verify the installation was successful by typing git --version: $ git --version git version 2.9.2 Configure your Git username and email using the following commands, $ git config --global us

LINUX APACHE MYSQL PHP LAMP is an archetypal model of web service stacks, named as an acronym of the names of its original four open-source components: the Linux operating system, the Apache HTTP Server, the MySQL relational database management system (RDBMS), and the PHP programming language. The LAMP components are largely interchangeable and not limited to the original selection. As a solution stack, LAMP is suitable for building dynamic web sites and web applications. Since its creation, the LAMP model has been adapted to other componentry, though typically consisting of free and open-source software. For example, an equivalent installation on the Microsoft Windows family of operating systems is known as WAMP and an equivalent installation on macOS is known as MAMP. Step 1: Install Apache Apache is a free open source software which runs over 50% of the world’s web servers. To install apache, open terminal and type in these commands: sudo apt-get update sudo apt-get inst
