Open Source and Complexity theory hold the strategic keys to managing risk in the age of terrorism.

Computers pose no threat to humans beyond Microsoft's blue screen of death and fatal-error messages.

The problem [with the Internet] is that it was devised by a bunch of hippie anarchists who didn't have a strong profit motive. But this is a business, not a government-sponsored network.
—Tom Nolle
The Internet did not replace TV, newspapers, magazines, Sears, the US Postal Service, Barnes & Noble or grocery stores in people's daily lives. It augmented them.
—Jason Kottke
Proprietary software developers are all doing something wrong, but this doesn't mean they are all incompetent.
—Richard M. Stallman
Networking is simply the cultivating of mutually beneficial, give and take, win-win relationships. It works best, however, when emphasizing the “give” part.
—Bob Burg
Advertising is, and always will be, inherently ludicrous, and is generally deserving of satire.

“Linux is not portable (uses 386 task switching etc.), and it probably never will support any thing other than AT-hard disk, as that's all I have.” --Linus Torvalds, August 25, 1991 The Current Ports of Linux web site reminds us how far Linux has come by providing information and links on on architectures to which Linux is ported thus far.

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?
