AVSynthesis: Blending Light and Sound with OpenGL and Csound5
The AVSynthesis config.xml file includes entries for changing the program window size. AVSynthesis defaults to the current screen settings, and it will fail to launch if it can't validate the dimensions given in the config file. Alas, I was unable to launch the program in any screen mode other than my default dimensions (1280x1024).
The Csound phase vocoder opcodes are very CPU-intensive. AVSynthesis has crashed randomly when I use the effects based on those opcodes, though it works fine with them at other times.
The render.wav file and the data/render directory must be cleared by the user; AVSynthesis will overwrite the current contents.
Sound may become distorted when using the Analog Synth 2 and the Wild Grain processor. Use the mixer to balance audio output from the synths.
AVSynthesis is well worth the effort required to make it happen. The further I get into AVSynthesis, the more possibilities I discover that warrant yet deeper exploration, and I can see (and hear) myself staying involved with the program for quite a while. The program's author has stated that he intends to squash remaining bugs and add some new features, but he wants to keep AVSynthesis as uncomplicated as possible. You can check out the latest version yourself, and with this guide's assistance, you should be running AVSynthesis quickly and smoothly under Linux. Have fun, be creative, and be sure to let Jean-Pierre know how you're using his software.

Realizing the promise of Apache® Hadoop® requires the effective deployment of compute, memory, storage and networking to achieve optimal results. With its flexibility and multitude of options, it is easy to over or under provision the server infrastructure, resulting in poor performance and high TCO. Join us for an in depth, technical discussion with industry experts from leading Hadoop and server companies who will provide insights into the key considerations for designing and deploying an optimal Hadoop cluster.

Built-in forensics, incident response, and security with Red Hat Enterprise Linux 6
Every security policy provides guidance and requirements for ensuring adequate protection of information and data, as well as high-level technical and administrative security requirements for a system in a given environment. Traditionally, providing security for a system focuses on the confidentiality of the information on it. However, protecting the data integrity and system and data availability is just as important. For example, when processing United States intelligence information, there are three attributes that require protection: confidentiality, integrity, and availability.

How to Build an Optimal Hadoop Cluster to Store and Maintain Unlimited Amounts of Data Using Microservers
Realizing the promise of Apache® Hadoop® requires the effective deployment of compute, memory, storage and networking to achieve optimal results. With its flexibility and multitude of options, it is easy to over or under provision the server infrastructure, resulting in poor performance and high TCO. Join us for an in depth, technical discussion with industry experts from leading Hadoop and server companies who will provide insights into the key considerations for designing and deploying an optimal Hadoop cluster.
Some of key questions to be discussed are:
- What is the “typical” Hadoop cluster and what should be installed on the different machine types?
- Why should you consider the typical workload patterns when making your hardware decisions?
- Are all microservers created equal for Hadoop deployments?
- How do I plan for expansion if I require more compute, memory, storage or networking?

thanks
thanks dave, you save me many hours of work with a clean doc on installation, usage, and rendering... i love avsynthesis
update 5/02
AVS has gone through a series of updates since I wrote this article. Please see the AVS Web page for more information. Significant improvements include randomization controls, a version for JOGL (intended to replace the LWGL dependencies), and better image-size support.
