Simulators for Training Firefighters
As testing progresses, we hope these visualization and simulation technologies can help meet ever-expanding training needs for both military and civilian emergency response teams. Applications for this limited prototype include pretraining practice runs for rescue workers and navigational training for workers unfamiliar with the environment.
Future plans and upgrades to this software are a bit more ambitious. One use for the system is as a scenario-driven classroom/firehouse trainer. It will include instructor-steered or preconfigured scenarios in which the trainer reacts to trainee/student input and adjusts the scenario accordingly. This will be supported by physics-based modeling of fire/smoke/heat and so on. As with the prototype, future iterations of this software will be available in various display configurations, from large/multiple-screen classrooms to PCs and laptops.
In addition to the scenario-driven training, this software also is planned to be a post-exercise debriefing tool. The location of trainees in a training environment, such as Randall's Island or a burn building, can be tracked at any time during the training exercise. Trainers could replay the training event, showing participants' locations at given times. Planned features include split-screen displays that could show participants' individual viewpoints during the exercise as well as the bird's-eye view.

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
