On the Web - Multimedia
Our new products mailbox has been receiving a lot of press releases introducing new workstations designed specifically for high-end audio and graphic needs. If you're an animator, filmmaker or a recording engineer who uses Linux, hardware and software companies are very interested in getting your business. But, even if you're a regular desktop user, Linux developments in audio and video matter, because at least some of them eventually will make their way into a desktop distribution. So this month, we're going to point you to some LJ Web articles that discuss what is going on in the Linux multimedia world.
If you're interested in a sound card that lets you do more complicated audio tasks, such as recording and mixing music, Peter Todd discusses “Using the Hammerfall HDSP on Linux” (www.linuxjournal.com/article/7024). The Hammerfall is a professional-grade sound card used in studios all over the world; it also happens to run under Linux, thanks to the ALSA Project drivers. It consists of an external module called the Multiface coupled to an internal PCI card. Peter explains that the big difference between the Hammerfall and regular sound cards is that the HDSP “is designed as a sound I/O device. It has inputs and outputs, and you can route sound between them arbitrarily.” The article also explains how to use advanced features such as an external time code source, a must for the studio.
In the early spring of 2003, Dave Phillips, author of The Linux Book of Music & Sound, attended the first conference held specifically for Linux audio developers. The report he wrote for us, “Linux Audio Development: A Report from Karlsruhe” (www.linuxjournal.com/article/6762), provides an overview of the main issues discussed at the conference, as well as the directions Linux audio development is taking. Among the topics discussed was JACK, the software toolkit that “provides a professional-grade audio server in a low-latency environment, making arbitrary audio signal routing possible, without dropouts or distortion.”
Moving on to the video portion of our presentation, Roberto de Leo's article “Self-Hosting Movies with MoviX” (/article/6474) explains how de Leo came to start the MoviX Project for a self-hosting movie—“a Linux CD mini-distribution that is able to boot and play automatically all audio/video files on the CD.” The main point of the article, however, is to walk users through the process of building their own mini-distributions, whether for playing a movie or some other application.
Finally, Geoff Draper wrote an article for us, “The Art of Rewriting Old Games” (www.linuxjournal.com/article/7083), in which he recounts how nostalgia for an old favorite, Nellan Is Thirsty, led him to rewrite the old 8-bit text game. The new version, Thirsty Nellan, “replaces the command-line parser interface of the original game with a point-and-click GUI environment.” He also used Alias|Wavefront for the scenery, which we must admit, is some of the cutest penguin artwork we've ever seen. Because many of these old 8-bit games are in the public domain, they too can be re-created for another generation of gamers. Read the article to learn exactly what Draper did, and then go rescue your own old favorite.
If you do rewrite an old game, set up a music studio or edit films on your Linux machines, drop us a line and let us know how you're doing it. And, be sure to check the Linux Journal Web site often. New articles are posted daily.

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
