Linux Journal Issue #181/May 2009
We don't own the desktop yet but we do own the first ever Nobel Prize in Cool. Cool Projects that is, we've got a Linux powered rocket and a Linux powered submarine. Plus we show you how to use the iRobot Create with Linux, how to convert those old 8mm movies to DVD with Linux, and how to control your house with Linux and Mi Casa Verde. After checking out the cool projects don't miss the rest of this cool issue and read how to run Rails under Apache using Phusion Passenger, how to build a secure Squid Web Proxy, how to use OpenFiler to create an open-source network storage appliance, and if just typed "rm -rf /" find out what to do and what not to do in our continuing series of "When Disaster Strikes" articles. And don't miss our interview with Neuros CEO Joe Born or Doc's monthly words of wisdom.

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?

WHERE OH WHERE DID THEY GO?
Kill off Dave Taylor and his idiot ramblings and bring back the VINO!
Francois will be back!
No fear, Francois is back in the next issue.
