As with most things in my life if I don’t get excited about using it constantly and don’t feel like I can control every aspect I lose focus. This blog in particular has suffered as a result of my choice of CMS and I feel like I need so I’m going to redesign my online [...]
NHS colour swatch
I’m currently working on a #nhssm Infographics Kit that should help NHS staff to create awesome Infographics without a complete knowledge of illustrator.

This is why the modern personal computer is set up with the mouse being the primary method of interaction, it allows users to feel like they [...]
A tool to help with creating gdal_translate commands
The Geospatial Data Abstraction Library (GDAL) is an awesome library for all kinds of map and geospatial based transformations and calculations. I’m currently using it to add a custom overlay on the map in an iPhone app I’m making. When making a custom overlay you use the GDAL’s gdal_translate function to create an image file [...]

Recently I was a bit naughty a shelled out around £210 for some kit that would help me with my music project. I had just installed Logic 8 onto my Mac Pro and found that my PS Eye, which I had used for recording purposes before hand was no longer usable so I decided to [...]
iPhone SDK, NSXMLParser and multiple child nodes into an array – Getting rid of whitespace
I’m currently making my first iPhone app for work, it’s designed to be an enhanced version of the leaflet given out to patients when they first arrive at the hospital. My idea was to take the information within and make it into something more iPhone friendly. On my journey through the magical world of iPhone [...]
Have some fun with the new ‘timeline’ Facebook Layout using GIMP/Photoshop

I’ve activated the new ‘timeline’ Facebook layout on my profile and decided to have some fun using GIMP to make a funny picture. I’m a massive Katamari fan and I love internet humour so I decided to add the running girl to a Katamari scene. Here’s a short tutorial on what to do. Grab a [...]
