Home Entertainment Linux MP3 Player
The technology to do almost anything with the music is already available. In my opinion, without Linux and open-source software, the task of building such a remote-directed MP3 player would be much more difficult. Since my Linux server is up 24/7, it makes sense to use it any time I want to listen to music as well. Although the system I dedicated for it is a rather modest one (Cyrix 6x86 running at 166MHz), the MP3 player is using around 40% of the CPU time when playing, and there are no audible interruptions even when concurrently serving web pages. In addition to compressing all my CD collections and storing them on my Linux server as MP3 files, I also digitized my old tapes and, after some processing of the sound in order to improve it, stored them in the same music hierarchy tree. Finally, I could remove all the CDs and tapes from my living room and store them away for good. Now, every musical piece is quickly accessible by a touch of a remote-controller button.

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
