UNIX Systems Programming: Communication, Concurrency, and Threads by Kay A. Robbins and Steven Robbins
UNIX Systems Programming: Communication, Concurrency, and Threads is the successor to the 1995 Practical UNIX Programming: A Guide to Communication, Concurrency, and Multithreading. This updated second edition includes all-new chapters covering the Web and multicast, plus a completely revised and updated remote procedure call (RPC) chapter. Material on files, signals, semaphores, threads and client-server communication also has been updated and enhanced.
The book provides programming exercises for many fundamental concepts in process management, concurrency and communication. These programming exercises are similar to the exercises you would be doing as part of an operating systems course. Exercises are specified for systematic development, and many can be implemented in under 100 lines of code.
Another important feature of the book is compliance with the POSIX standards, the single UNIX specification adopted since the publication of the first edition.
The book provides everything you need to program with threads, TCP/IP and RPC. The authors explain the essentials of UNIX programming, concentrating on communication, concurrency and multithreading techniques, and why, when and how to use them in a tutorial manner. They provide a lot of reusable source code examples, all complete and ready to be compiled and run.
Another nice feature of the book is that it shows how to design complex software to get the best performance from a POSIX system. Many short examples are featured throughout the book, as are a number of hands-on projects that help readers expand their skill levels. The authors take a practical approach and use short code snippets to illustrate how to use system calls.
I highly recommend adding this book to your UNIX library if you want to learn UNIX system programming essentials with a concentration on communication, concurrency and multithreading techniques. It is the book that will keep you wondering how you were working without it.
Practical Task Scheduling Deployment

One of the best things about the UNIX environment (aside from being stable and efficient) is the vast array of software tools available to help you do your job. Traditionally, a UNIX tool does only one thing, but does that one thing very well. For example, grep is very easy to use and can search vast amounts of data quickly. The find tool can find a particular file or files based on all kinds of criteria. It's pretty easy to string these tools together to build even more powerful tools, such as a tool that finds all of the .log files in the /home directory and searches each one for a particular entry. This erector-set mentality allows UNIX system administrators to seem to always have the right tool for the job.
Cron traditionally has been considered another such a tool for job scheduling, but is it enough? This webinar considers that very question. The first part builds on a previous Geek Guide, Beyond Cron, and briefly describes how to know when it might be time to consider upgrading your job scheduling infrastructure. The second part presents an actual planning and implementation framework.

With all the industry talk about the benefits of Linux on Power and all the performance advantages offered by its open architecture, you may be considering a move in that direction. If you are thinking about analytics, big data and cloud computing, you would be right to evaluate Power. The idea of using commodity x86 hardware and replacing it every three years is an outdated cost model. It doesn’t consider the total cost of ownership, and it doesn’t consider the advantage of real processing power, high-availability and multithreading like a demon.
This ebook takes a look at some of the practical applications of the Linux on Power platform and ways you might bring all the performance power of this open architecture to bear for your organization. There are no smoke and mirrors here—just hard, cold, empirical evidence provided by independent sources. I also consider some innovative ways Linux on Power will be used in the future.Get the Guide
