American ELTEC unveiled an embedded Linux camera no larger than an ordinary surveillance camera. Available in both color and monochrome versions, the miniHiPerCam is based on an embedded version of ELINOS. The CMOS image sensor operates at a 640 × 480 pixel resolution and a frame rate of 15 or 30Hz. The built-in controller board uses a PowerPC 823 processor running at 50MHz. 16MB of memory is available for images and runtime data, and the OS with an embedded HTTP server and the application software are stored in 8MB of Flash memory. The camera has two RS-232 ports and one 10Mb Ethernet port.

Black Lab v2.1 is a cluster build and management suite for HPC clusters running Yellow Dog Linux. It offers single-click installation and configuration, automated updates through apt-get, a graphical user interface, control of multiple clusters and command-line control of all services. The new version incorporates BProc 3.0, which automatically migrates applications and shared libraries from the server to selected nodes. This setup allows each node to operate with a minimal installation on its local drive. Administrators can customize nodes with only the necessary software installed by designing their own server-side node images.
EMJ Embedded Systems announced the latest release of white dwarf linux, an embedded OS designed for 10MB of Flash memory and 16MB of DRAM. white dwarf linux supports any motherboard or single-board computer with IDE support and at least 8MB of RAM. It also supports CD and network installs. Version 1.2 includes kernel version 2.4.19, a graphical package-based installer, and GCC development tools for glibc 2.2.5. white dwarf linux works with the DIMM-PC 486 and 520, MOPS686+, CoolMONSTER and Tri-M MZ104 boards.

Ampro Computers has a new MIPS-based module for embedded systems. The EnCore M3 combines AMD's 400MHz MIPS32 Alchemy Au1500 chip with standard EnCore features to provide a complete standards-based CPU subsystem on a small form-factor module. The EnCore M3 is rated at 480 Dhrystone MIPS with a typical power consumption of less than 2.5 watts. The module features a 32-bit, 66MHz PCI Bus Interface. EnCore M3 is 100 × 145mm in size, and it includes two 10/100 Base-T Ethernet controllers and an AC97 audio interface. It supports up to 256MB SODIMM SDRAM and provides 2MB of Flash, two serial ports, two USB ports, a floppy disk controller, PS/2 keyboard and mouse ports, IrDA port and an ECP/EPP bidirectional parallel port.

Practical Task Scheduling Deployment
July 20, 2016 12:00 pm CDT
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
