equivocation: ambiguity or uncertainty of meaning in words; misapprehension arising from the ambiguity of terms; the using of a word or phrase in more than one sense. OED

The equivocation web site is primarily a set of personal notes about software, techniques, and other topics I find interesting or useful. Why is it called "equivocation"? Because descriptions of software and computer related techniques easily succumb to equivocation. I will endeavour to avoid this (although, I don't promise to succeeded).

Google AdSense and AJAX

Currently, Google AdSense is not very AJAX friendly. If you have a website that loads content via AJAX and there is also an AdSense ad on the page, ideally you would like to have the ads replaced with new ones appropriate to the new content at the same time the new content is loaded. AdSense provides no mechanism to do this. The popular work around is to put the AdSense code in an iframe with a list of keywords or content in that frame that the AdSense uses to choose appropriate advertisements but the user does not see. This works, but is a little messy (replicating content or keywords, and hiding them off page so they can't be seen).

Accessing the contents of a KVM disk image

A kernel based virtual machine (KVM) can use either an entire partition to simulate a disk for the guest operating system, or a single file. By default the file type used is a "raw" file compatible with other virtualization systems, like Xen. Other optional file types are more flexible, allowing compression and encryption of the contents (qcow2), or compatibility with VMware (vmdk). Access to the simulated file sytems contained within the file from outside the guest operating system is possible. For example, access from the host or real Linux system.

Using the Virtual Manager to install a KVM guest

A virtual machine (VM) is a software implementation of a computer. Systems that implement virtual machines provide a way of managing the underlying real/physical machine so that it can be split up between different virtual machines, each running its own complete operating system (called a "guest").

Resizing a root LVM volume

Logical volume management (LVM) is the default method of partitioning on Fedora Linux. It provides a more flexible way of partitioning disks and media on top of the traditional Linux partitions. However, in a similar manner to traditional partitions, resizing a LVM partition (or "volume" in LVM speak) is not necessarily a simple task.

Installing Fedora 8 on a Dell XPS M1330

I have just had the chance to use and work with a Dell XPS M1330 notebook. It is not as small and light as my old Toshiba portégé R200, but it has a slightly larger 13.1 inch wide screen and built in DVD burner. It came installed with Microsoft Vista. As my primary work currently requires Linux while still being able to run/use certain Microsoft based software, I decided to set it up dual boot. I like Fedora, so will try out the latest Fedora 8 version (currently in test 3, so things should not be that different when the final Fedora 8 comes out).
