I have been working to get some Xenservers setup in the same pool that have different CPU versions. With different features, I get the error message that the CPUs are not homogeneous. To help rectify this, I created the following script and then followed the instructions below. /root/get-cpu-features #!/usr/bin/perl $FEATURES2=$ARGV[0]; if (exists $ARGV[1]) { $FEATURES1=$ARGV[1]; […]

A Poor Man’s Solution for Automatic ISP Failover

Why the public cloud is the fast food of the IT industry.
The challenge for any IT manager is how to meet business requirements with technology. More often than not, those requirements dictate rapid deployment. The cloud excels at this, since the infrastructure is already available and waiting to be used. Rapid deployment, just as fast-food, does not guarantee quality, however.

Cloudsourcing – What is this “IT revolution” all about?
First there were servers. Each server had a single purpose.

For example, we think of a “telephone”, not a network of transducers wired through hubs and switches that create temporary channels that bridge calls together. It is natural for us to add layers of abstraction that help us to understand the […]

Malaysian Flight 370 Search
Why are we not using drones/UAVs (Unmanned Aerial Vehicles) to scour the ocean for Flight 370? With all of the news about how UAVs can stay aloft for lengthy periods of time, why have we heard nothing about them being deployed and used for the search of flight 370?
