  • Knowing right from wrong
    I try to be a good person. I hope that I can leave the planet a tiny bit better than I found it; at worst, I hope I do not leave a negative impact. But I get confused about rights and wrongs. Just when I think I know where I stand, I encounter someone else […]

    It is nearly 8 years since I moved to my house. I was moving from Cirencester to Malvern, where Libby lived. We had become tired of the one-hour drive between our homes, so I made the move to see how things might work out. We married about 2 years later, so you can draw your […]

  • Industrial Internet of Things architecture

  • Throwing away my DSLR camera
    I see endless adverts for accessories to help me take better picture with my phone. There are numerous articles describing iPhone photography techniques that make amazing claims. The bottom line often seems to be that you no longer need a “real” camera – a DSLR – an iPhone will do everything. The truth of these […]
