Learn the intermediate concepts of python programming today! Python is on the rise in the world of coding and many popular technological devices from the Raspberry Pi to the Linux operating system use Python as a crux for not just education, but implementation. Python can help you code your own software, develop your own games, and even format your own home surveillance system! It is, hands down, one of the most useful coding languages around, and the way it is formatted cuts out a great deal of the fluff that other coding languages have a tendency to be bogged down with. Whether your interest in Python is educational, career-based, or born out of a simple curiosity, it is a programming language you should know, be fluent in, and put on your resume. This world is quickly evolving into a technology-based society, and knowing a coding language as prominent as Python will not only ensure you a job in the future, but it will provide you with a thick foundation to then build your coding language on, should that be something you are chasing. However, no matter the purpose you have chosen for learning this language, there is no beginner’s book that breaks down the language into its original components and strings them together cohesively better than this one. If you are looking for a book that is easy to understand and still provides the easy to digest guidance you want, then look no further than here! 1. Language: English. Narrator: Trevor Clinger.

Master the system calls at the heart of today´s UNIX and Linux systems: the programming interfaces that drive the UNIX and Linux kernels and run everything from filesystems and multitasking to interprocess communication. A thorough knowledge of system calls is essential for every UNIX and Linux programmer -- and for 20 years, W. Richard Stevens´ Advanced Programming in the Unix Environment has delivered that. Now, Stephen Rago has completely updated this classic to reflect modern distributions including Red Hat 2.6.x, Solaris 10 3, OS X 10.5.4, FreeBSD 7.0.5 -- and for the first time, Ubuntu. As in previous editions, Rago begins with essentials such as file and process control, carefully laying the groundwork for more advanced techniques. He supports his crystal-clear explanations with nearly 10,000 lines of code, all carefully tested on each of these leading versions and distributions. Rago begins with an up-to-date overview of the UNIX System, its standardization processes, and its diverse implementations. Next, he introduces file I/O, files, directories, and the Standard I/O Library. You´ll walk through working with UNIX/Linux system data files and information? controlling the process environment and its relationships? using signals, threads, and daemon processes? mastering advanced I/O techniques, interprocess communication, sockets, and advanced IPC? using Terminal I/O and Pseudo Terminals? working with database libraries, communicating with network printers, and much more. Appendices provide essential information on function prototypes, miscellaneous source code, and solutions to many of this guide´s exercises. For all intermediate-to-advanced level UNIX programmers and software engineers. Product Description For more than twenty years, serious C programmers have relied on one book for practical, in-depth knowledge of the programming interfaces that drive the UNIX and Linux kernels: W. Richard Stevens? Advanced Programming in the UNIX® Environment . Now, once again, Rich?s colleague Steve Rago has thoroughly updated this classic work. The new third edition supports today?s leading platforms, reflects new technical advances and best practices, and aligns with Version 4 of the Single UNIX Specification. Steve carefully retains the spirit and approach that have made this book so valuable. Building on Rich?s pioneering work, he begins with files, directories, and processes, carefully laying the groundwork for more advanced techniques, such as signal handling and terminal I/O. He also thoroughly covers threads and multithreaded programming, and socket-based IPC. This edition covers more than seventy new interfaces, including POSIX asynchronous I/O, spin locks, barriers, and POSIX semaphores. Most obsolete interfaces have been removed, except for a few that are ubiquitous. Nearly all examples have been tested on four modern platforms: Solaris 10, Mac OS X version 10.6.8 (Darwin 10.8.0), FreeBSD 8.0, and Ubuntu version 12.04 (based on Linux 3.2). As in previous editions, you?ll learn through examples, including more than ten thousand lines of downloadable, ISO C source code. More than four hundred system calls and functions are demonstrated with concise, complete programs that clearly illustrate their usage, arguments, and return values. To tie together what you?ve learned, the book presents several chapter-length case studies, each reflecting contemporary environments. Advanced Programming in the UNIX® Environment has helped generations of programmers write code with exceptional power, performance, and reliability. Now updated for today?s systems, this third edition will be even more valuable. Features + Benefits W.
