Unix (trademarked as UNIX) is a family of multitasking, multiuser computer operating systems that derive from the original AT&T Unix, developed in the 1970s at the Bell Labs research center by Ken Thompson, Dennis Ritchie, and others.
Initially intended for use inside the Bell System, AT&T licensed Unix to outside parties from the late 1970s, leading to a variety of both academic and commercial variants of Unix from vendors such as the University of California, Berkeley (BSD), Microsoft (Xenix), IBM (AIX) and Sun Microsystems (Solaris). AT&T finally sold its rights in Unix to Novell in the early 1990s, which then sold its Unix business to the Santa Cruz Operation (SCO) in 1995, but the UNIX trademark passed to the industry standards consortium The Open Group, which allows the use of the mark for certified operating systems compliant with the Single UNIX Specification (SUS). Among these is Apple's OS X, which is the Unix version with the largest installed base as of 2014.
From the power user's or programmer's perspective, Unix systems are characterized by a modular design that is sometimes called the "Unix philosophy", meaning that the operating system provides a set of simple tools that each perform a limited, well-defined function, with a unified filesystem as the main means of communication and a shell scripting and command language to combine the tools to perform complex workflows. Aside from the modular design, Unix also distinguishes itself from its predecessors as the first portable operating system: almost the entire operating system is written in the C programming language that allowed Unix to reach numerous platforms.
Linux (pronounced i/ˈlɪnəks/ LIN-əks or, less frequently, /ˈlaɪnəks/ LYN-əks) is a Unix-like and mostly POSIX-compliant computer operating system (OS) assembled under the model of free and open-source software development and distribution. The defining component of Linux is the Linux kernel, an operating system kernel first released on 5 October 1991 by Linus Torvalds. The Free Software Foundation uses the name GNU/Linux to describe the operating system, which has led to some controversy.
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. Thanks to its dominance on smartphones, Android, which is built on top of the Linux kernel, has the largest installed base of all general-purpose operating systems. Linux, in its original form, is also the leading operating system on servers and other big iron systems such as mainframe computers and virtually all fastest supercomputers, but is used on only around 1.6% of desktop computers with Linux-based Chrome OS taking about 5% of the overall and nearly 20% of the sub-$300 notebook sales. Linux also runs on embedded systems, which are devices whose operating system is typically built into the firmware and is highly tailored to the system; this includes smartphones and tablet computers running Android and other Linux derivatives,TiVo and similar DVR devices, network routers, facility automation controls, televisions,video game consoles, and smartwatches.

Demo of using threads in Linux (pthreads) to run very simple processing in parallel. Uses a mutex (pthread_mutex) to synchronize the processing to avoid a race condition. Topics: - Timing the process without using threads (Linux time command) - Switching processing to new threads - Running multiple threads without a mutex lock (race condition) - Solving a race condition - Timing the multi-threaded version - Common problem when passing arguments to a thread - Common problem spotting race conditions Links: Create a single thread: http://youtu.be/ynCc-v0K-do Eclipse Setup: http://youtu.be/E36QpJdEghg Linux programming play-list: https://www.youtube.com/watch?v=E36QpJdEghg&list;=PL-suslzEBiMrqFeagWE9MMWR9ZiYgWq89

https://github.com/gotbletu/shownotes/blob/master/rsync_examples.txt NAME rsync - a fast, versatile, remote (and local) file-copying tool DESCRIPTION Rsync is a fast and extraordinarily versatile file copying tool. It can copy locally, to/from another host over any remote shell, or to/from a remote rsync daemon. It offers a large number of options that control every aspect of its behavior and permit very flexible specification of the set of files to be copied. It is famous for its delta-transfer algorithm, which reduces the amount of data sent over the network by sending only the differences between the source files and the existing files in the destination. Rsync is widely used for backups and mirroring and as an improved copy command fo...

You'll learn several rsync options as well as best practices for using rsync. Based on Don's book The Accidental Administrator: Linux Server Step-by-Step Configuration Guide, this video covers the basics of using rsync on CentOS Linux and Red Hat Linux.
