Linux Journal Live - Horror Stories
The October 30th edition of Linux Journal Live focused on Horror Stories in the computer world. We discussed the ghostly ipchains, the dreaded rm -rf, and even the sinister dd dilemmas we've faced over the years. If you missed the live show, be sure to watch the recording... before it accidentally gets erased! (Just kidding, we learn from our mistakes, the video is totally backed up!)

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?

Horror Stories
I have two for you. Hardware related, no simple "hope you had a backup" here ;-)
Back in the early days of the Internet when an ISP meant banks and banks of modems in a small room. When working on a BSDi system I crawled under the table to plug in a SCSI drive. I managed to catch the pull cord for the window blinds in the plug. These were the the old style vertical blinds with the metal beaded pull cord. One spark and the power went out for the entire room. Not a happy day...
Years later I was moving equipment from one ISP in Santa Cruz over the mountains to MAE West. I had done the trip twice already, all I had to do now was get the equipment in the rack and powered on. I had a hand cart loaded with servers from the back of the car and a bag with my laptop and cables is over my shoulder. Its late, in the 2-3 am range, and Im very tired. Im alone and the streets are deserted. I steer the cart towards the handicap ramp and I miss the little bump at the bottom. The cart stops, the servers go crashing down onto the curb. Panic! After what seemed like an eternity of staring at the servers on the ground all showing signs of road rash, I gather everything up and get into the facility. Everything is mounted and up and running, with only some minor rebending of mounting tabs. I escape without anyone knowing what just happened. Months later another admin asks me why one of the servers has a huge dent on the side of it. Had to love that VALinux hardware, dented and bruised but kept running!
