RTcmix for Linux: Part 1
RTcmix is an incredibly powerful and flexible package because of the work of many people, and possible because of its open-source nature. Different features have been added by different people over the years. It continues to evolve. The Linux operating system has been an excellent platform both for development and performance. With the recent advent of high-end, multichannel digital audio card support for Linux (e.g., the RME Digi96 series), the abilities of RTcmix grow in conjunction with the OS.
This article only scratches the surface of RTcmix's potential. Future articles will discuss in greater depth the process of writing RTcmix instruments and controlling them in real time (e.g., with nice open-source GUI packages like GTK).
In the end, it remains amazing to think that a computer, operating system and software package can work together well enough to make music. It is, however, by no means new thinking. Ada Lovelace apparently debated at length with Charles Babbage the virtues of this “new computing device”. His contentions had to do with an unbeatable chess player, hers about a device that could compose and create music of any type or degree of complexity.
David Topper (email@example.com) is the technical director for the Virginia Center for Computer Music at the University of Virginia. Linux has been his primary OS since downloading 40 floppies' worth of Slackware (kernel 1.0.9) as a CS undergrad. It is one of his firmest beliefs that the computer can be to the human mind and spirit what the telescope was to the ancient astronomers, provided free software like Linux continues to thrive.

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
