I have updated the page showing my household temperature graphs. Previously I was logging data to the cloud using Pachube and while this works well, the tools available for graphing the information are not great. As the number of readings increased, the tools I was using to render the graphs became slower and slower. What’s more the graphs used flash which wasn’t particularly helpful if I wanted to view the graphs on my iPad. I have now reverted to some home brew data logging using RRDTool. Data is stored in a Round Robin Database and then rendered using some more …

I’ve recently taken a free trial from Netflix UK with the intention of evaluating it as a replacement for Sky Movies.

I added a couple of simple buttons to the screen, configured them to send the correct UDP …
