Linux is an open source operating system based on Unix that can be installed on various devices. Open source software has source code that anyone can inspect and modify. Popular Linux distributions include Ubuntu, Linux Mint, Debian, and Fedora. To build an open source application, you need a Linux distribution and programming knowledge. The Quickly tool can be used to create, edit, package, and publish applications in Ubuntu. While open source offers advantages like security, customization, and free software, disadvantages include a lack of standardization and unsupported hardware. Common myths about open source include it being insecure, having few applications, being too difficult for non-programmers, and having no copyright restrictions.

4. What Is Linux and What do you mean by
Open source
The Linux is an open source operating system, or Linux OS, is a
freely distributable, cross-platform operating system based on
Unix that can be installed on PCs, laptops, netbooks, mobile and
tablet devices, video game consoles, servers, supercomputers
and more.
Open source software is software with source code that
anyone can inspect, modify, and enhance. "Source code" is the part of
software that most computer users don't ever see; it's the code
computer programmers can manipulate to change how a piece of
software—a "program" or "application"—works.

5. Popular Linux Distribution and Open
source software
 Ubuntu
 Linux mint
 Debian
 Fedora
 SentOs
 Opensuse
 Mageia
 Arch Linux
 Pupy Linux
 Tweak Tools
 GIMP
 Dropbox
 VLC Media Player

6. How to Build a open source application
Need a Linux Distribution
Basic Knowledge about programming language Python is probably better for that.
Developing applications "Quickly"
For Building a open source app we are using A Linux distribution known as Ubuntu.

7. How to Install “Quickly” tool
Using this we can create an useful
application, edit our code , run it,
test it, generate package or we
published that in Ubuntu software
center.
This process may not work
for newer Distribution . For
that we need to download
quickly.tar.gz file from internet

8. If you don’t find the Quickly Tool
 Then Use this tool
 Qt tools
 Qt Creator
 Creating user interfaces with Qt Creator
 Qt 5
 QWidgets
 Ubuntu SDK for developers
 PaythonGtk
 GTK+
 PySide
 PyQt
 Gtk
 PyGtk
 Java and Swing
 Mono
Just search it on
google.And get the
link.

9. Create an application,design and edit it
This command for creating a Ubuntu
application:
quickly create Ubuntu-application myapp
change the current directory and for edit or
design our application:
cd myapp
To design our code:
Quickly design
To edit our new application code:
quickly edit

10. To upload it Ubuntu software center:
Quickly package
Push it all Launchpad:
Quickly release
Create an application package and launch it

11. Edit an Application source Code
apt-get source pkgname
For google Chrome, you would type “google-chrome” instead of
“chrome”. Try again if you at first not succeed.
Example:
$sudo apt-get source gimp
[you'll end up with something like: gimp_2.8.14-1.debian.tar.xz
gimp_2.8.14-1.dsc gimp_2.8.14.orig.tar.bz2]

12.  Linux is free of charge and in case you still doubt, then know
that it is.
 Linux is more secure than any other server
 It has a wide compatibility to several hardware
 Easy to Operate
 It comes inclusive of drivers
 Smooth and easy Updating Process
 Linux is speedy
 Linux features a powerful word processing program
 Linux has a community support
 Linux offers you a chance to download a lot of free tools
why should we use linux

13. Advantages Of Linux
