Has scanning under Linux improved?
Conclusions

It was a little disappointing that I couldn't get the buttons on the scanner to work, but that ended up being the only roadblock in the whole process. The main lesson is to get the driver for your scanner, then worry about the rest. Scanning under Linux has improved a lot since I last played with it, and I'm really excited to take something off the list of things I have to do on another operating system.

Updates for Previous Columns

Updates on Qimo:

My instructions for getting Qimo to use more modern packages were not detailed enough [see “A Desktop for Our Little Penguin” in the February 2010 issue]. Unfortunately, the original computer I built died before I could get the files off the drive. The good news is that Qimo 2.0 should be out by the time you read this. That version will be in sync with Lucid (10.4) and save you a lot of hassle.

Updates on APT Caching

Eric Cooper, the author of Approx, contacted me about my comments that his software did not handle multiple computers at once [see “Installation Toolkit” in the March 2010 issue]. He pointed out that the criticism might have been from an earlier version. The current version of Approx uses inetd/xinetd, so they do not suffer from that limitation. That means you have several good choices for caching packages on your network! Sorry for the mistake Eric. That's what I get for reading a blog and being in a hurry.

Fabric-Based Computing Enables Optimized Hyperscale Data Centers

Today’s modular x86 servers are compute-centric, designed as a least common denominator to support a wide range of IT workloads. Those generic, virtualized IT workloads have much different resource optimization requirements than hyperscale and cloud applications. They have resulted in a “one size fits all” enterprise IT architecture that is not optimized for a specific set of IT workloads, and especially not emerging hyperscale workloads, such as web applications, big data, and object storage. In this report, you will learn how shifting the focus from traditional compute-centric IT architectures to an innovative disaggregated fabric-based architecture can optimize and scale your data center.

Red Hat White Paper: Using an Open Source Framework to Catch the Bad Guy

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.
