At LinuxWorld New York in January 2001, Lineo announced the SecureEdge hardware brand, a OEM development platform for fully brandable Linux-based applications and devices. SecureEdge replaces the NETtel product line. The first SecureEdge product available is a VPN Internet router that secures office-wide Internet connections. Connections can be by dial-up, ISDN, cable or ADSL modems.
The VPN router can also function as an embedded Linux platform running a uClinux kernel, enabling it to function as a thin server. Custom programs, such as firewalls or monitors, can be written, stored in Flash memory and executed inside the router/server. Features of the SecureEdge routers include:
Browser-based management and configuration with an embedded web server
Telnet access and remote management
Serial ports supporting speeds up to 230Kbps
Optional 4-port hub for SOHO
Universal Plug and Play
USB interface for any USB device
Lineo provides the complete development environment as standard. Application development can be done independently or in conjunction with Lineo to decrease time-to-market of customized, brandable appliances.
Model: SecureEdge VPN Router

First in series of application-specific motherboards.
Alberta Microelectronic Corporation (AMC) introduced a new family of high-performance, integrated, application-specific motherboards with its first release, the Single Board Internet Computer. The motherboard uses Celeron technology with standard embedded PC product features. Contained in 53 square inches of board space, the single module's level of integration can be used for a wide range of embedded applications.
The SBIC is based on the Intel 440BX AGPset and uses the IEEE 1394 Link Layer Controller that uses digital interface for throughput devices like digital cameras and scanners. Other features include a low power mode, a 100MHz front-side bus with L2 Cache and PC100 SDRAM performance. The mainboard attempts to eliminate add-in boards by including the Ethernet and FireWire directly onto the circuit card.
Programming the SBIC can be done with standard languages, and it is compatible with most popular operating systems. AMC provides engineering support and is available to assist developing and supporting software for specialized applications.
Manufacturer: Alberta Microelectronic Corporation
Model: Single Board Internet Computer
Suggested retail price: $400 in volume
Generate small standards-based graphic solutions for embedded applications.
In January 2001, Metro Link announced that all future eBSD operating systems sold will include Metro-X for host development and a demo of Micro-X, a scalable embedded X server. Developers will be able to use the demo to simulate the X server and run it on a set-top box, web-pad or other next generation internet appliance design.
Micro-X can be configured to as little as 570K resulting in small memory footprints. Additionally, host and target embedded systems can use the same platform, aiding application development. Developers will be able to display embedded 2-D and 3-D graphics, video-in-a-window and MPEG playback on internet appliances, consumer electronic devices or multimedia devices running eBSD on multiple architectures.
Manufacturer: Metro Link, Inc. and BSDi
Model: eBSD with Metro-X and Micro-X

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
