How to Pick a Distribution
This is a potential deal-breaker that can narrow your distribution choices fast. If you will need to run a proprietary program on your system, check the vendor's list of supported distributions. If the vendor only supports the program on one or a few distributions, stick with one of those even if you think you can get the program to run on another. If you run into a problem and have to go to the vendor for support, you want to be able to rule out the Linux distribution as the problem's source and go straight to the real issue.
Where will you be getting support for your operating system? From the distribution vendor, from a consultant or from your local user group? If you'll be using a consultant, ask that person which distribution you should use. He or she will be much more helpful to you if he or she is on familiar territory. If you're going to a user group for support, identify the most helpful posters on the mailing list, and pick a distribution they know and use.
If you can, put this item last. You'll be happier picking out hardware you know works well with your distribution of choice rather than trying to make Linux work on random hardware. If you already have the hardware, and won't be buying more, check the hardware compatibility lists of the distributions you're considering. If you don't know what's inside your case, use the world's best hardware detection utility: a Philips screwdriver.
You should probably be down to a short list of distributions by now. Browse their web sites for security updates. Is it easy to tell what updates you will need to install in order to make your installation from CD-ROM current and secure? Also, look at the security mailing list. Does the distribution provide timely security advisories and updates?
Some distributions can do automatic software upgrades over the Net. This can be a great time saver and a relatively painless way to stay current on security updates. If the idea of upgrading with one command or a few clicks sounds good to you, check to see if a potential distribution offers this feature.
Nobody only installs once. As a hobbyist getting started, you might install a couple of times and then blow your system away, either by mistake or because you decide you don't like something. In a business, you'll need to be able to install quickly, either to recover from a crashed disk or to deploy a new system.
Browse different distributions' install instructions on-line. Look for an install that will save time in the long run, not just one that offers a pretty GUI. You'll want to look for the ability to make all the decisions up front, then let everything install unattended. Better yet, look for the ability to make a floppy that includes all your preferred options, so you can boot from the floppy and walk away while the install does itself.
Now that you've chosen a distribution, this is the best time to look for hardware. You will have the luxury of a supported hardware list, plus hardware picks from your source of support--either user group mailing list archives or a consultant's recommendations. Keep your list with you when you shop, and don't forget to check ``Linux'' on your warranty registration card.

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
