The Past and Future of Linux Standards
Is it enough for Linux developers to make their own way based on standards developed by outside groups such as the IEEE, The Open Group, ISO and ANSI? Probably not. Linux developers have been able to pick and choose which standards to adopt and how to implement them, but as standards are revised and extended, Linux developers want to ensure future standards also meet their needs.
One such revision in progress is a joint revision of the POSIX standards by the IEEE, The Open Group and ISO. The group revising the standard is known as the Austin Group. Unlike previous POSIX standards, the goal is a common set of documents shared by all three organizations. USENIX, the Advanced Computing Systems Association, is helping to fund two Linux developers to attend meetings and participate in the revision. The two developers are Ulrich Drepper, the glibc maintainer, and H. Peter Anvin, author of the kernel automounter and maintainer of the Linux device list. The POSIX revision, Ulrich says, will throw away or at least make optional some of the less wanted parts of the old standards (such as STREAMS). This is a good thing for Linux because those parts have not been adopted by the entire Linux community. The result is that fuller compliance with POSIX will become more likely.
In addition, Ulrich adds, there are functions he would like to see standardized in the new POSIX specification. Some of those function specifications may come directly from the glibc project. If that happens, maybe some future operating system can put some of the standardization blame on Linux.
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
