I wrote a python add-in for MonoDevelop last year. Unfortunately, I have a hard time sticking to a single project and therefore it suffered a bit. However, we are getting ready for feature freeze for MonoDevelop 2.2 and so I kicked my ars in gear to fix a few things.

What happens when a cracker breaks into a virtual machine and takes it over? What happens if there is a bug in the hypervisor?

Network device drivers have been using the increasingly misnamed NAPI ("new API") interface for some time now. NAPI allows a network driver to turn off interrupts from an interface and go into a polling mode. Polling is often seen as a bad thing, but it's really only a problem when poll attempts turn up no useful work to do.

Today's tutorial will be on the infamous Quorum disk. When I first setup my GFS2 shared Cluster of 3 nodes, I was quite impressed with the fact that 3 nodes were sharing the same file system. Now that everything was up and running, I wanted to see what would happen if I brought down, 2 out of the 3 nodes in the cluster.

Last week we provided benchmarks of Ubuntu 9.10 Alpha 4, but Ubuntu is not the only Linux distribution preparing for a major update in the coming months. Also released in the past few days were OpenSuSE 11.2 Milestone 6 and Mandriva Linux 2010.0 Beta 1. To see how these three popular distributions compare, we set out to do our usual Linux benchmarking dance.

RAID 1 is usually implemented as mirroring; a drive has its data duplicated on two different drives using either a hardware RAID controller or software (generally via the operating system). If either drive fails, the other continues to function as a single drive until the failed drive is replaced.

I know. It sounds crazy. But hear me out. They are antithetical not because of the philosophy, but simply because the nature of the products that they make. Linux makes “backend” stuff, while Apple makes “user-facing”/”frontend” stuff. So, they do not compete. And their philosophy is similar.
