From the Editor - Freedom, the 64-bit Way
Freedom and DVDs, unfortunately, make an explosive combination. In the US, a judge cited the controversial Digital Millennium Copyright Act (DMCA) in a decision banning our technology journalism colleagues at 2600 from even linking to one DVD-descrambling program, DeCSS.
In other countries, though, whether you can play DVDs on your Linux box depends on whether you let your government impose a DMCA-like law. Today, the UK Campaign for Digital Rights (ukcrd.org) and other organizations are trying to prevent DMCA-like laws from taking effect in Europe.
While the legal sniping continues, we're getting more and better free, open-source DVD software for Linux. Dave Phillips covers his favorite players and some DVD-playing tips on page 42. Ian Pointer shows how to make your own DVDs with menus and background music on page 50. By the time DVD-playing software for Linux comes under attack outside the US, it won't be merely a C program on a Web site. As Linux desktop adoption continues to grow, DVD software for Linux will run on millions of desktops that users take for granted.
And, those users are voters and jurors too. A California jury acquitted Elcomsoft, a Russian software company that developed software to convert proprietary “e-books” to open formats, of DMCA charges. That's not surprising, considering that California jurors probably are used to desktop applications and don't think selecting “Save as...” from the File menu is a crime. Jury foreman Dennis Strader told the San Jose Mercury News, “Under the eBook formats, you have no rights at all, and the jury had trouble with that concept.”
It's hard to sell a product without a demo, and freedom needs a demo too. So it's a race. Can freedom lovers deploy software that gives people a chance to experience their digital rights before governments take those rights away? Congress' attempt to impose mandatory digital rights management in the US didn't go anywhere, so the incredibly versatile effects builder Pure Data (page 60) is safe for now, as is the jukebox at Chez Marcel (page 24). The more people are used to doing something, the harder it would be to take away.
Gaining an ally in the struggle for freedom and justice—what better reason to build someone a Linux system? When you read Glenn Stone's article on page 36, build an Ultimate Linux Box for a family member or friend, too. The Ultimate Linux Box gets to be more of a bargain every year, even as we add 24/96 audio and move up to the 64-bit AMD64 architecture. Turn up the volume, put on some Oggs, break out the power screwdriver and enjoy this issue.

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?
