The Tetra hardware platform from Equator Technologies provides a compact and modular reference design that allows rapid development of products such as IP smart cameras, digital video recorders and IP-based internet streaming video appliances. The modular design includes the Tetra CPU board, an open peripheral interface for add-on modules and various add-on personality modules. All common CPU board core features, such as the BSP chip family, memory subsystems and Ethernet interface, are on the CPU board for a final size of 2.75" × 4". It comes with 64MB SDRAM and 4MB Flash memory; analog audio out and SPDIF audio in/out, 10/100Base-T Ethernet; and support for Linux or VxWorks.

RackSaver offers its latest entry in the blade server market, the BladeRack (patent-pending). The BladeRack houses up to 66 RS-1100RV RackBlades, each containing up to two 2.4GHz Xeons for a total of 132 processors in a 7' portable cabinet. AMD-based processors also may be used. The BladeRack can be configured with 66GBs of DDR ECC PC-2100 Corsair memory, based on Supermicro's P4DPR-6GM+ motherboard. In addition, the BladeRack is easily scalable and accessible, with hot-swap capabilities for the fans, networking equipment and servers themselves. Using nonproprietary, interchangeable off-the-shelf components, the BladeRack is targeted at 3-D rendering, research centers, universities and other data-intensive uses.
Xcelerix announced the formal launch of the company and the general availability of Xcelerix In-Memory Database (IMDB), formerly known as ERDB. Xcelerix IMDB's architecture prejoins database tables based on known operational queries and uses binary tree indexing, helping to eliminate bottlenecks and enabling up to one million transactions per second (SQL benchmark results). A small footprint and a 20:1 compression of memory resources ratio allows the Xcelerix IMDB to be embedded in response-sensitive, real-time applications. It is available in both 32- and 64-bit versions for a variety of platforms. Xcelerix IMDB supports integration with disk-based database systems, in addition to SQL, TCP/IP, IEEE 802.3 and POSIX.

Cypress Semiconductor released a Linux USB host driver that supports their SL811HS embedded host/peripheral controller, enabling developers to add USB host functionality to a variety of embedded applications, such as cell phones, PDAs and network appliances. Because the SL811HS controller is a memory-mapped device, the driver lets the Linux host stack provide USB support without realizing a non-OHCI/UHCI type host controller is present. The SL811HS host controller has a dual-role port that can function as either a USB host or a peripheral supporting both full- and low-speed USB devices. Source code for the driver is available at www.cypress.com/press/linux.

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
