Linux Programming Hints
The GNU C Library Reference Manual is an amazingly large and comprehensive work. While it's not perfect and is still being written, it contains a lot of information. I do not know if it is being published on paper, but it's available via ftp from all gnu mirror sites and can easily be printed or formatted for on-line reading from within emacs or the standalone info reader.
I'll take some space here to plug, as usual, some of the books that I have found most helpful, books which I think that my readers should not be without.
When you are programming for modern variants of Unix, you ought not to be without W. Richard Stevens' Advanced Programming in the Unix Environment, which has most of the information you need to write real applications under most variants of Unix. Both the principles and the details are covered. ISBN: 0-201-56317-7
For learning how to write POSIX compatible programs which can run on more than just Unix platforms (rather the opposite of this month's column, I'll admit), I recommend Donald Lewine's POSIX Programmer's Guide. It's hard to go wrong if you follow this book. ISBN: 0-937175-73-0
I'm open to suggestions on what programming hints people would like to see. Please send email to email@example.com or send paper mail to Programming Tips, Linux Journal, P.O. Box 84867, Seattle, WA 98145-1867, and I'll consider your suggestions. If you have any books which you really like and which you would like to see me recommend in this column, please recommend them to me. I'd appreciate a detailed description of any book which you find indispensable as a Unix programmer.

Practical Task Scheduling Deployment
July 20, 2016 12:00 pm CDT
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
