In a recent blog article I used WordPress to embed images into a posting. This was very simple to do but there is a drawback: The image embedded within the post is identical in size and resolution to the one viewed if the image hyperlink is clicked. This makes the post and initial webpage very… Continue reading Image Manipulation

Goodbye Green Fields
Since moving into the village of St Mellion, almost two years ago, I’ve walked our dogs, Ollie and Murphy two or three times every day in some local fields. Sadly (for me) today is likely to be the last time as the fields will be mostly gone by tomorrow. The land has been purchased by… Continue reading Goodbye Green Fields
Encrypted Filesystems Revised
Some years back I blogged about encrypted filesystems. That info is still valid but times have moved on and there are other, better ways now. I can’t take any credit for this info, it all comes from the blog of Lars Strand. My thanks to him for taking the trouble to make it public. I’m… Continue reading Encrypted Filesystems Revised

Hardly surprising, considering the impact it has on the security of the OS. There is… Continue reading Broken Debian Openssl

This got me thinking about whom I actually trust when I’m using the Web. Most people install an Operating System and simply trust whatever Certificate Authorities it happens to come with. A… Continue reading Who do I trust?
Domestic 3-Way (or more) Lighting Circuit
Sometimes you might want more than two switches on a lighting circuit. For example, one switch at each end of a hallway with another at the top of the stairs. If you have a big landing, you might even want four switches! Here’s how you do it. The third switch is referred to as an… Continue reading Domestic 3-Way (or more) Lighting Circuit
Domestic Switched Light
The following diagram shows the most simple of lighting circuits, a single lamp on a single switch. In this instance I’ve shown it with an incoming and outgoing supply as this can be achieved without breaking the rule of not putting more than four cables into a single junction box. The next diagram shows a… Continue reading Domestic Switched Light
Domestic 2-Way Lighting Circuit
The following diagram shows my preferred method for wiring a domestic 2-way lighting circuit. In this context, 2-way implies that two switches attach to the same light. In the above diagram, the Supply and Light cables are standard 3-core (Live, Neutral and Earth). The Switch cables are special 4-core used specifically for this type of… Continue reading Domestic 2-Way Lighting Circuit
