Access to knowledge is critical to securing a fair and free society.
Linux is a computer operating system (OS) that is developed, assembled and distributed under the model of free and open-source software.
The computer operating system is the computer program called the kernel. The kernel executes and manages the execution of other software programs, interfaces with the physical machine and manages I/O (input/output) requests from software.
Linux was originally developed as a free operating system for personal computers based on the Intel x86 architecture, but has since been ported to more computer hardware platforms than any other operating system.
The Android system that is used for smartphones is built on top of the Linux kernel and has the largest installed base of all general-purpose operating systems.
Linux is also the leading operating system on servers and large scale systems such as mainframe computers and supercomputers. Linux also works on some devices whose operating system is implemented in firmware. Examples of this include routers, video games, watches, television controllers, etc.
"The development of Linux is one of the most prominent examples of free and open-source software collaboration. The underlying source code may be used, modified, distributed-commercially or non-commercially by anyone under licenses such as the GNU General Public License."
The Linux kernel is packaged with libraries, supporting utilities, applications and other programs to form a distribution. The programs that make up a distribution may be focused on providing either a desktop or server environment. They may also focus on some specific aspect or capabilities for either desktop or servers.
Anyone can create a distribution or a collection of Linux software for any use. Some of the most widely used Linux distributions are described below:
Debian GNU/Linux is a distribution that supports many hardware platforms. Debian and distributions based on it use the .deb package format and the dpkg package manager and its frontends. Debian is known for being well-tested and bug-free. Many consider Debian as a distro for experienced users. The version release cycle is slow with stable releases coming out every one to three years. Debian provides more than a pure OS: it comes with over 43000 packages, precompiled software bundled up in a nice format for easy installation on your machine. Debian
Ubuntu is a distribution based on Debian, designed to have regular releases, a consistent user experience and commercial support on both desktop and server. It has a predictable, six-month release schedule and is also notable for its ease of use and its inclusion of a migration assistant for Windows users. It is also know for its support of new technology. Ubuntu
Fedora is the community supported distribution based on Red Hat Linux. Fedora is particularly strong on enterprise features and has a standard a six-month release schedule. It uses the RPM format for software distribution and updates. Fedora
Linux Mint is an Ubuntu-based distro. It differs from Ubuntu with custom themes, different applications, graphical tools for enhanced usability, such as mintDesktop for configuring the desktop environment, mintInstall for easier software installation and mintMenu for easier navigation. Mint is one of the most user friendly distributions. Mint
Puppy Linux is a compact distro that's ideal for older hardware and situations where computing resources are minimal. The live-CD typically being 85MB, yet there is a complete set of GUI applications. The whole OS is small enough to run directly from system RAM. The system is extremely responsive and applications start quickly and respond instantly. Puppy
Arch Linux is a simple, lightweight and flexible Linux. A good deal of the configuration has to be done by the user. It is generally consider as a distribution for experts. Arch
There are more than 100 current Linux distributions. Check distrowatch if you are interested in investigating more.
The King James Bible (kjv), World English Bible (web) and Bible in Basic English (bbe) are all examples of public domains books. The King James Bible (kjv) online uses the content from these books and open source software to enhance Bible study capabilities. The site includes the verse of the day, search tools, christian literature and links to related content. It demonstrates the use of open source to create a valuable service.

The The Library of History by Diodorus the Sicilian is one of the most highly regarded universal histories in antiquities. His work includes the history of Egypt, Asia, Africa, Greece and Europe. His book is a must read for research of ancient history.
The Histories of Herodotus written in 440 BC is considered to be the founding work of history in Western literature. His history included stories and fables but he claimed to have traveled extensively and learned about many countries through direct observation.
The Bible study website was developed using open source software. The King James Bible online provides search tools for Bible verses, people, keywords and concepts. It demonstrates the use of open source to create a functional application and service.
Want to change a program or know how it works? Open Source provides the source code for its programs so that anyone can use, modify or learn how to write those programs themselves. Visit the GNU source code repositories to download the source.
The Free Books Library is a collection of thousands of the most popular public domain books. The collection includes the world's great classical literature and more recent works where the U.S. copyright has expired. These books are free of restrictions.
A man or manual page is a form of software documentation found on Linux/Unix operating systems. Topics covered include computer programs (including library and system calls), formal standards and conventions, and even abstract concepts.
The thesis of Stolen Legacy is that the Egyptians created what is wrongly called Greek philosophy. Dr. James argues that the African origin of Greek Philosophy is well known but rarely discussed. Ancient Greek historians such as Herodotus and Diodorus the Sicilian wrote in significant detail about the contributions of Egypt. Egyptian technology and libraries were unmatched and Greek philosophers such as Pythagoras and Plato studied there. The contribution of Africa to the intellectual foundation of modern knowledge is tremendous but unacknowledged.
