VariCAD has significantly rebuilt its eponymous 3-D/2-D mechanical CAD system—which is no stranger to the Linux platform—with release 3.0. At its heart, says VariCAD, the multiplatform (Linux, Windows) product is a fully loaded package that offers not only “powerful tools for 3-D modeling and 2-D drafting and dimensioning”, but also “libraries of standard mechanical parts (ANSI, DIN), calculations of standard mechanical components and tools for working with bills of materials and blocks”. Innovations in the new version include “improvements in the STEP interface allowing input and output of 3-D objects, new high-resolution bitmap output from 3-D, new user-defined default settings, improved file opening and dimensioning” and others. A Linux-specific improvement is reduced dependence on system files, allowing the software to run on more distros. A free trial version (Debian or RPM) is available for download from VariCAD's Web site.
Arcom recently released its SBC-GX533 Development Kit for developing embedded devices in a Linux environment. The target applications, says Arcom, are “deeply embedded, remote or unattended installations demanding reasonable processing power”, typically industrial RTUs and data acquisition modules, as well as networking and communications devices. The SBC-GX533 is a low-profile, fanless, RoHS-compliant, EBX-form-factor board with a 400MHz AMD Geode GX533 1.1W processor, 512MB of DDR DRAM and 32MB of Flash, of which only 13MB are occupied by the preloaded Linux image. The Linux OS is kernel 2.6 with a Compressed Journaled Flash File System (JFFS2) for reliability and recovery from power interruptions. One of the SBC-GX533's key advantages is the preconfiguration of the Linux image, which preempts the need to build it from scratch. A few of the optional features are TFT, analog touchscreen and Java Technology.
Like other vendors in the diverse hardware arena, Supermicro has upgraded its product line to take advantage of Intel's new Dual-Core Xeon 5100 series processors, aka Woodcrest. The new platform is slated to improve system performance and memory capacity, as well as reduce energy consumption and operating temperatures. Supermicro has leveraged Intel's advances to improve its own systems, or SuperServers, that are based on its X7 series of motherboards. Supermicro claims that the combination of its high-efficiency power supplies and the Woodcrest processors result in “5% or greater efficiency than competitors' systems”, providing energy savings of “up to $200 per server over three years”.

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
