Take Linux with You Wherever You Go
Sharp Electronics is taking orders for their Zaurus SL-5000D (developer edition) Linux/Java PDA from developers beginning in November 2001. The price for the developer model is $399 US, and it includes 32MB DRAM and 16MB Flash.
The device is based on a 206MHz Intel StrongARM system-on-chip processor, and it has a 3.5" 240 × 320-dot pixel (quarter VGA) reflective TFT 65,536 color LCD with touch-panel support and, of course, runs an embedded Linux operating system. The software stack is based on Lineo's Embedix, Trolltech's Qt Palmtop Environment, Opera's web browser and a PersonalJava v1.2-compliant Java runtime environment. Two expansion slots are provided: a secure digital (SD) card slot, used mainly for Flash memory, plus a CompactFlash slot used for communications interfaces, a digital camera attachment, Flash memory and more.
A unique and highly desirable feature of the SL-5000D is its full QWERTY keyboard, which is accessed by sliding the bottom portion of the device downward. See developer.sharpsec.com for more information.

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
