    Episode 18 - The origin of the Internet of Things with Peter Lewis

    Episode 18 - The origin of the Internet of Things with Peter Lewis

    Most people think the Internet of Things is a recent idea, maybe dating to around the year 2000.  In fact, the idea is some 15 years older than that.

    In 1985, the Internet was officially two years old. It linked up some 2000 hosts, and a handful of people used email. In that year, cellular phones were the size of bricks, and almost no one had one. And yet, in 1985, Peter T Lewis predicted the two could be combined, so devices could communicate over wireless links.

    "I predict that not only humans, but machines and other things will interactively communicate via the Internet," he said. "The Internet of Things, or IoT, is the integration of people, processes, and technology with connectable devices and sensors to enable remote monitoring, status, manipulation, and evaluation of trends of such devices."

    Listen to our podcast to find out how Lewis made this astonishingly accurate prediction, years ahead of his time. in a speech to the Congressional Black Caucus Foundation in 1985. We also find out how his ideas were almost forgotten, and what he thinks of today's IoT.

    Episode 17 - The impact of climate legislation on digital infrastructure with Stephen Harper, global director of Intel

    Episode 17 - The impact of climate legislation on digital infrastructure with Stephen Harper, global director of Intel

    After a hiatus of several years, climate change policy is taking off in the US, with the Biden-Harris Administration using the Inflation Reduction Act and the Energy Earthshot to accelerate the clean energy economy.

    But data center energy policy goes back a lot further than that. Stephen Harper, Intel's Global Director, Environment and Energy Policy, was there 20 years ago when data centers first came onto the climate change radar, and he's been tracking progress since then.

    As well as their own emissions "footprint", data centers have a positive impact on emissions elsewhere, known as the environmental "handprint"

    But how do we measure that handprint, and set it against the negative impact of infrastructure.

    And coming after this backstory, just what impact of these Biden-Harris initiatives have?

    DCD speaks to Stephen about the likely impact of historic climate legislation for the digital infrastructure sector.

    Episode 16 - Green software with David Mytton, CEO and co-founder of Console

    Episode 16 - Green software with David Mytton, CEO and co-founder of Console

    Efforts to reduce the environmental impact of our digital world tend to start with the cooling systems at data centers, and rarely get any further.

    The tech industry created PUE as a simple metric which could express how efficiently power is delivered to the racks, but did not consider what happens to that power when it gets there.

    That’s not good enough, because poorly written software could be wasting that power in unnecessary loops and fruitless calculations.

    The Green Software Foundation has emerged to propose a measure of Software Carbon Intensity that will tell developers if their software is a good planetary citizen.

    But this is an issue that gets more complex, the more you look at it. Software that completes quickly must save energy, but what if the software is running on multiple hardware platforms? What about the embodied energy of the hardware you choose for it?

    David Mytton is Co-founder & CEO of Console, a company that makes tools for developers. He’s also looked at the energy used in technology, bothy at Imperial College and at the Uptime Institute.

    He’s now working on a PhD in sustainable computing at the University of Oxford.

    He talks to us about the prospects for Green Software finding its way from academic research, through sponsorship by large vendors, into the hands of developers and consumers.
