TALOSS: Three-Dimensional Advanced Localization Observation Submarine Software
A flexible, modularized, 3-D data fusion visualization system has widespread applicability for both military and civilian applications. Under the sponsorship of the Office of Naval Research (ONR), the Naval Undersea Warfare Center, located in Newport, Rhode Island, has created such a system for the visualization and integration of the submarine undersea battlespace. This system, TALOSS, has been designed to integrate a wide variety of the databases, both civilian and military. Because the software is modularized and written to run under Linux, it has the potential for transition as an open-source rendering and data fusion engine.
The ultimate aim of the project, funding permitting, is to develop a completely modularized TALOSS toolkit, unclassified portions of which will be made available for civilian use as open-source software. There are two primary motivations for this release: 1) the software was developed with public funds and should be made available to the general public if national security is not compromised, and 2) by making the unclassified portion of the software available, it is hoped that improvements in its operation by the Open Source community can be incorporated into the classified portion of the software enhancing its operation.

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
