The Distributions Take a Stand on Standards
Pacific HiTech will take an active role in the development of Linux standards and will make compliance with the adopted standards a design goal of all our Linux products. We believe a well-defined set of Linux standards is important so that ISVs can more easily port their applications to the Linux operating system without worrying about distribution compatibility.
I'd like to see them develop to the point where any compliant distribution will have the same shared libraries available and the same basic file-system structure. Some people have suggested that a standard package manager would also be important, but I'm not necessarily sure that's true—for example, .deb and .rpm can both provide a system in which a given third-party application could work, provided that the shared libraries and path structure are the same. What I would like to see is a common system for “registering” applications so that desktop managers and other programs would have a standard method of determining what is installed on the system.
Slackware is waiting to see what the proposed standards are before we commit to complete compliance, but I do think the effort is a step in the right direction for Linux. I'd really like to see a list of standard version numbers to use when building shared libraries—that should be a simple first step in getting binary compatibility among the distributions back on track. However, the standards should probably not go into such detail that all distributions end up looking cut from the same cookie cutter. It is the different design philosophies which make different Linux distributions appeal to different kinds of users. It'll be interesting to see how these issues are balanced.
The general stance of Debian is that standardization is a good thing. Dale Scheetz is a Debian developer and actively involved in the LSB work. LSB is also an SPI-supported project. As Linux continues to grow, it will become more and more important for vendors producing software to know it will run on a number of different distributions without requiring distribution-specific versions. The growth of Linux will be greatly helped by applications being ported to run on it, and this growth must be supported as much as possible.
Debian has been involved in the LSB project from the beginning. One of our developers, Dale Scheetz, is working on the LSB right now. We've been talking with Red Hat since before LSB so that we can develop binary compatibility between the distributions. The important system libraries should be fully compatible across all distributions. We don't want to see the kind of incompatibilities suffered by users of 16-bit MS Windows software when they upgraded to 32-bit MS Windows. Debian is currently working to adopt the File Hierarchy System, but we feel a few issues remain to be resolved. Debian is happy to help create standards and compatibility with the other distributions; the LSB is one of the methods we are using to make this happen.
SuSE has been a member of the Linux community since 1992, and we have people dedicated to and working on the LSB project. We are proud to be active members of this project. We are hoping to see some sort of minimum library standards because that is what our customers want. ISVs need that kind of standard to work efficiently. Hardware vendors deserve a standard in order to certify their hardware across distributions.
It's my personal opinion that standardization is good thing. But like always, too much of a good thing can be a bad thing. It really all depends on which aspect of the Linux system you want to standardize, and how much. Where do you begin and where do you stop? If we standardize the file system layout, packaging and user tools, is anything left? I'm not sure of LSB's plan—but from my reading, it doesn't look like they have a well-laid-out plan quite yet. Standardizing file locations is a great idea; I know it would solve half of the problems I encounter. I read somewhere LSB plans on having a standard packaging system. That is a tricky subject for me to even personally comment on—we have a lot of plans for our Stampede Linux Packaging system (SLP). There are some features the standard may not include that we'd like to have. Obviously, we can contribute to the project ourselves, but if the majority doesn't like our idea, then it won't go in. The great thing about Linux is that if you don't like something, you can't complain. Don't use it, find something else, hack the source code, or start a whole new project. If a situation like this arises, the user who wants a feature can no longer search for another package; he must try and somehow convince the authors to add it.
At this time, two extremes are apparent: one is “everyone does their own thing, their own way” and the other is “everyone does what the standard says”. I'd like to think we aren't at either of these extremes right now. That fine line between them needs to be found, and when someone finds it, I'll be able to comment further.
Currently, with the information we have, Stampede's stance is neutral, but this could easily change. It could change tomorrow, next week, next month or next year (just like any Linux-related project). For now, I will try to keep a close eye on what goes on and keep others of the Stampede development team informed. It will be much easier to make a decision once a clearly defined set of rules has been set.
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
