The Open Development of Debian
Since the early days of Debian, I have described it as the first distribution of Linux to be developed openly in the spirit of the operating system and the free software movement. My justification was the success of the kernel; after all, open and distributed development had worked so well for the kernel, why couldn't it work just as well for a distribution?
The justification made sense, of course, but the reality was not quite that simple. Before any open development could be done, a cohesive development group had to be organized, a solid foundation upon which to develop had to be made available, and most importantly, it had to be proven that open and distributed development could actually work for a distribution. At the beginning, there were many strong supporters of Debian, but there were just as many people who said that it simply could not be done.
For the first months of the project, although many volunteers helped prepare Debian for distribution, I was the one who actually assembled the version to be released, since the guidelines for creating all the pieces of the distribution changed from day to day as we improved the system. Also, the most recent versions of most of the guidelines were often only to be found in my head.
Because one person has limited time, I could only do this job by myself for so long, while the system was still small, even with volunteers helping get many of the pieces ready. As the guidelines began to stabilize, and as the system became large enough that I could not put the system together single-handedly (as I found out when I tried), it became clear that the time had come to take the next step.
With an organized system for creating the Debian distribution in hand, the volunteers who had already been helping to create Debian packages were able to step forward and take complete responsibility for them, without fear of anarchy. They can package their own software, knowing that it will fit smoothly into the rest of the Debian system.
It has been a rough ride, but the Debian project survives and is stronger now than it has ever been. We are organized, we have a solid foundation coming in the release of Debian 0.93 BETA, and, as proven by the support that Debian has received and the enthusiasm of the Debian project volunteers, we have proven that the idea of an openly-developed distribution can work. I remain the maintainer of the base system and several development packages, and I serve as the leader of the project as a whole. But I am now only a part of a larger movement, a movement that is gaining momentum. So, what does all of this mean to the users of Debian?
We have many well-respected members of the Linux community directly involved in the development of Debian. We have experts working directly on the parts of Debian involving their area of expertise. We have package maintainers that closely follow new releases of the software that they are packaging, and in many cases, participate directly in the development of the software itself.
We now have drafted guidelines which define the construction of Debian binary and source packages. With the help of these guidelines, package maintainers may put together packages that are consistent with those put together by other package maintainers. The Debian leadership checks to ensure that each package is assembled correctly and that the system as a whole is solid; the end result is a set of packages that, though developed and maintained by many different individuals, are as consistent and as professionally constructed as if they were developed by a single person or closely-knit group, but without the limitations imposed by centralized development.
No longer does one person have to shoulder the burden of constructing every package. As mentioned earlier, I maintain the base system and many of the development packages; others maintain the networking packages, the XFree86 packages and so on. When a new component is available, the package maintainer may simply update that package and make the newest version available, without a complete update of Debian. The days of massive, comprehensive re-releases of Debian are over; each component of Debian will be fairly independent of all others, and it will be easy for the end-user to upgrade his system or any component of it.
And, most importantly, need I mention that you, too, can become involved!
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
