OpenGL Programming on Linux
The project, for all the work-teams in our course, is now finished as far as it involved students working on a programming project whose results professors would evaluate. I finished the final “product” pretty much alone and about a week before all the other teams. In the end, our game client probably had the greatest number of features, the most complex graphics, the nicest explosions and the most reliable motion engine—and we got the highest marks possible on the final evaluation by the professors. Somehow, I think that if I had not been able to run everything on my home Linux machine, and do everything when I wanted it and how I wanted it, I probably would not have reached this level of achievement.
Other than showing that some Computer Engineering students are definitely more productive on their home machines than on most computers you can give them access to, this somewhat extraordinary adventure shows that some fields—which, until now, were reserved for high-end workstations—can be explored with something as simple as a good Linux box and some relevant software.

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
