Linux Journal Issue #178/February 2009
Stop me before I program again! Well, at least stop me till I get a chance to read this month's Linux Journal and find out all the latest related to Web Development. Don't write another line of JavaScript till you get a chance to check out our articles on Dojo drawing tools and jQuery. If you're just plain tired of JavaScript, maybe it's time to look at the Google Web Toolkit—get some of the hottest JavaScript on the planet without writing a single line of JavaScript (you read that right). If you're a Ruby type, get further faster and look good while you're at it with ActiveScaffold. And, if you're looking for some new site creation tools, don't miss this month's Cooking With Linux column. If you've got some extra coin and need a Netbook, see our review of the Dell Mini 9. If you're looking for a portable media player, see our review of the Archos 5. For you Second Life fans, see our introductory article on the game and its open-source nature. And, if you're a reeeeaaaaaal Second Life fan we have an extra special treat for you: we put your picture on the cover!

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?

Second Life Twink
I was exceedingly impressed with the leather and Levi clad simulacrum twink on the cover of the February issue, especially his well formed legs and impressive package. I am pleased that you are now appealing to a new audience and can see some follow-ups to this pic. How about a co-op ad joining Silicon Mechanics and Speedo or even Michael Phelps (in his usual uniform) demonstrating the Happy Hacker keyboard. I'll be renewing my subscription ASAP just to encourage you to keep up the good work.
