No Safety without Security on the IoT

We have reached the stage in the evolution of the Internet of Things (IoT) where two independent processes have become self-sustaining. The first—the creative process—has begun to uncover genuinely compelling applications. Beyond $40 internet lightbulbs, in-refrigerator Webcams, and toothbrushes with smartphone apps, systems developers are starting to see—and to prototype—applications at the convergence of smart […]

Neural Networks and the Rings of Power

In the dark world of J.R.R. Tolkien’s Lord of the Rings, the Dark Lord commanded the creation of a set of golden rings that embodied and projected his power. One in particular (Figure 1) held power over the others, with the ability to find them and bring them together. Figure 1. One ring ruled all the […]

New Layers Form within the Cloud

An air mass that begins life as a single huge cloud may separate, under the complex interactions of wind, temperature, pressure, and humidity, into several distinct strata with different characteristics. Similarly, today’s seemingly uniform cloud data centers are being transformed, through the emerging pressures of big-data computing and the Internet of Things (IoT), into multiple, […]

The Mathematics of Range Anxiety

Late at night, the student in the apartment is awakened by a strange smell. Investigating in the darkened rooms, she sees a burst of flame engulf her roommate’s hoverboard. There is only just enough time to get everyone out of the apartment before the rooms are fully involved. Near the end of the marathon, a […]

Data Center Ethernet: Is a Bigger Pipe Enough?

In the enormous pressures and temperatures far beneath the Earth’s surface, minerals take on forms impossible to replicate in our familiar environment. Hence carbon may become diamond, or graphite. Similarly, in the intense, dynamic environment of the data center, familiar Ethernet is taking on configurations unimaginable to its inventors at Xerox PARC. As with carbon, […]
