Cooking with Linux - Wherefore Art Thou, Oh Access Point?
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?

Wireless Assistant Anomolies
I'm constantly on the prowl for wireless utilities, etc. for Linux since I consider it the weakest part of the system I use daily. This article, Marcel, looked great!
I downloaded Wireless Assistant 0.5.5 from the Debian apt repository, and as far as I can tell, it installed correctly. What is confusing me more than almost anything else I've ever encountered is that I only seem to have half the functionality that you describe. I have no "Detect" button and no "Configure" button. I wuld normally think this might be version differences, but I can't understand why half the functionality would be deleted from this utility.
I'm using Debian Linux, Etch version, and KDE 3.5.
Great wifi tools
Marcel,
I've installed both wlanassistant and netgo today. They both absolutely rock! They are excellent solutions for managing wireless network connections.
If the two programs could be combined into one, they'd be perfect. I'm going to be testing them both out extensively.
Thanks for pointing them out. Dealing with multiple wireless connections was a big complaint of my wife on her laptop. Now she has one less thing to complain about :-)
