At the Forge: Why Linux?
Engineers are notoriously bad at keeping secrets, as Scott Adams has occasionally pointed out in his Dilbert comics. Indeed, one of the things that attracts me to open-source software is the fact that there are no secrets. Clients hire me because they want to save themselves time or because they lack expertise in a particular area, not because they are forced to do so. For this reason, I tend to think of myself as analogous to a lawyer or accountant, both of whom offer advice and documents based on freely available information.
This “no secrets” philosophy tends to work well with my clients, including those who aren't at all interested in knowing how the software works. They know they can ask me questions, and I'll give them the best answer I can, without having to hide behind marketing hype, mandatory updates or double-talk. My technical clients, of course, enjoy knowing they can dive into the code or read the documentation; the only thing stopping them from knowing what I know is time and experience.
My nonprofit clients, who are in many ways the perfect audience for open-source software, are often excited by the possibility of using such tools. In particular, I have found that educational institutions like the idea of sharing information and community involvement, in software as in other spheres of life. Telling them they can both save money and participate in a community of like-minded people is a powerful combination. Moreover, nonprofits typically have little incentive to keep changes within the company, meaning that they can more easily participate in the Open Source community.
When I first began to write this column for Linux Journal, most server-side web applications were handwritten CGI programs. A huge number of web sites still use such programs. But as the Web has become more sophisticated, people have demanded toolkits that make it easier to develop high-quality, scalable web applications in a short amount of time. It shouldn't come as any surprise that many proprietary software companies have come to fill this void. It is shocking, however, to find out how much money they want for their software—sold on the condition that their consultants are hired to customize it, followed by a mandatory service contract.
Luckily, the open-source world has responded. A number of open-source toolkits can be used for creating sophisticated server-side applications. Zope, as we have seen in recent months, is a fantastic (if complicated) application server, making it possible to create web applications that connect to databases and other information sources. Next month, we'll begin to look at OpenACS, designed to make on-line community systems easy to build and modify. Furthermore, such environments as mod_perl, Mason and the numerous Java- and XML-related tools sponsored by the Apache Software Foundation increasingly mean that locating the right tool can be as difficult as installing and using it.
But as wonderful as these toolkits are, we must remember that not everyone will be won over. My harshest lesson on this front came last year when a potential client decided against hiring me to create a simple content management system for producing a product catalog for the Web. I was told that my bid came in at $800,000 less than my closest competitor. However, because I was using open-source software and the competition was a well-known name in the world of content management, I lost out. (That client has had a round of layoffs and quarterly losses since then, and their web site still appears to be managed by hand, so at least I won a moral victory of sorts.)
We should also remember that not every player in the open-source sphere can be trusted to follow through on their promises to the community. Many open-source advocates were surprised and disappointed when Lutris pulled the plug on its open-source Enhydra Enterprise Java application server last year, turning it into a proprietary product. Luckily, there are alternatives; not only has the GPL-licensed JBoss application server dramatically grown in popularity over the last year, but Sun recently made it clear that nonprofit, open-source J2EE implementations will be able to receive official certification in the coming months. This should help to reduce further the stigma that some businesses associate with open-source software.
But even if you suffer setbacks, don't be fooled: as IBM, HP and even Sun now acknowledge, Linux and open-source software are powerful, stable and should be taken seriously. “World domination” hasn't yet arrived, but brand-name recognition, financial realities and admiration from academics and commercial entities alike are helping us move ahead.
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
