The Quick Start Guide to the GIMP, Part 2
Support for the PhotoCD format, available from Kodak Digital Cameras, was available in the 0.54 release of the GIMP last year. A quick check of the Plug-In Registry shows that the plug-in has not yet been ported (or at least not registered) for the 1.0 release. If you need this format, you should check with the plug-in author or check the Registry periodically to see if the plug-in has been registered. Note that plug-ins written for the 0.54 or 0.60 releases of the GIMP are not compatible with the 1.0 release. They must be rewritten using the GIMP 1.0 Plug-In API.
The alternative to raster graphics is vector graphics. There are a wide variety of image file formats that the GIMP supports for raster images, but it does not support any image files that use vector formats. This is only important if you wish to use one of the many ClipArt collections available for Windows systems; these files are often suffixed with .wmf. There are still many CD's available with image collections in TIFF or JPEG format that can readily be used by the GIMP. If you must have access to the vector ClipArt collections, use Applixware's Applix Graphics package or perhaps a Windows program to read them in and save them in a raster format such as TIFF, JPEG or GIF.
An emerging format that has recently gained wide acceptance is called PNG, the Portable Network Graphics format. Earlier releases of the GIMP support this format but, at the time of this writing, the plug-in providing PNG support has not yet been ported to the new 1.0 Plug-In API. I expect this to happen by the time this article is published. Again, check the Plug-In Registry to be certain.
We've covered a lot of ground but have only managed to open a file—we haven't done anything useful with it. Don't despair—we're getting there. Next month we'll cover the Image Window in more detail. A detailed discussion on layers will also be presented, which is very important to understanding how to get the most out of the GIMP. We'll briefly cover how filters work and discuss a few of the more interesting image-processing options available with filters. After that, in the final installment of this series, we'll cover the Toolbox in complete detail. At that point you'll have enough background to begin to do something really useful with the tools in the Toolbox.
I realize some readers will wonder why I don't cover the Toolbox before I cover filters. Well, it has to do with the length of each of these installments. The best way to fit everything into reasonably sized articles is to do the layers and filters section together. Since the Toolbox has so many tools, it will take a very long installment just to give a short introduction to each of them. Stay tuned: in the end, having the information from all four parts will be of benefit as you make the most of what the GIMP has to offer.
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
