Over the last decade or so we’ve passed a tipping point in the relationship between humans and machines without even noticing.
Users are lost in the noise
Windows, Android, iOS … all of today’s operating systems are now suffering from a malaise that runs deep, manifesting itself as a device which doesn’t respond when you interact with it. I don’t believe it is acceptable for a laptop, iPad or Smart Phone to just decide that it has more important things to do than pay attention to its user. Here are some thoughts on why this happens (which goes to the root of how we develop devices) and what we could do about it.
Over the past few months I’ve been doing a lot of thinking about the future of the Internet of Things – and how we’re all going to bring that future into the present. Some of this thinking has been with my most recent startup AlertMe, some with the IoTA forum led by ARM, and some at the Cambridge University Computer Lab where I’m currently a Visitor.
I first heard the ugly word “Co-opetition” in 1995 in Silicon Valley – and assumed it was as meaningless as it was unpronounceable. But gradually I’ve come to appreciate what it means and why it’s so important … and since its Wikipedia entry doesn’t really do it justice, I thought I’d share some thoughts here. Let’s start off with a more familiar word…
Why we need it – and how hard it is
I mentioned in my recent IET talk that the supply of electricity to the grid is likely to become increasingly variable as wind generation grows, and because as net energy importers we are increasingly dependent on foreign energy outside of our control. We don’t worry about this problem too much with gas because we can store it relatively easily in giant gasometers. If we could store electricity too that would be a huge help in de-stressing our electricity grid (and its engineers!).
[I ran out of room to include this topic in my recent IET talk]
As late as the 1880’s a debate was raging about whether to distribute electricity to our homes by Direct Current (DC), where the current always flows in one direction as from a battery, or Alternating Current (AC), where the current reverses direction many times a second. The prolific American inventor Edison advocated DC, while European genius Tesla advocated AC. It was called the War of the Currents (what is it with all these “war” analogies? Enough already!).
I cut my teeth in the computer industry, where for decades Moore’s Law has pretty accurately described the way that year by year computers become more and more powerful for a given price. Or put another way, that every year transistors become cheaper and cheaper. Is this perhaps due to some magical property of transistors? No – as the picture below shows, it was happening before transistors were even invented, and it will surely continue to happen even after we abandon silicon for optical or quantum computing:
Phew! After months of thought and planning, our home Solar Electricity (PV) Panels are finally up and running – just days before the government halves the FIT (Feed-In Tariff) subsidy.
Choosing what to fit… and who to fit it
There are plenty of good online guides about choosing and siting your solar panels. To receive the maximum subsidy you can fit up to 4kWp of panels (about 20) – enough to fill the roof of a largish house. Obviously they have to be largely south-facing and unshaded for much of the day!

In the developed world we’ve achieved 100% connectivity for humans and are working on connecting-up all the “things” around us too, offering the tantalising prospect of the Internet of Things – a world where autonomous devices get on with the business of making the world a better place, without needing too much attention from us. Or will they?
