The Infrastructure of a Smart City

Cities have always been built around and are dependent upon their infrastructure. Most early cities were built next to rivers or bodies of water. Water is needed for drinking and growing food and cleaning. Clay and rocks were used as construction materials, so proximity to sources that supplied them was a priority. Energy has always […]

The Future of Fog Computing

We have become used to the idea of “cloud” computing, which means both storing data and and doing processing that is distributed across many remote systems. We are just beginning to understand “the internet of things” (IOT) which is the concept that most “things” in our day to day life can become connected, can handle […]

Ethics and the Speed of Tech Improvement

Our technology is improving quickly and the rate of that improvement is steadily increasing. Technology always amplifies human effort. If the effort has been aligned ethically, the amplified end product will be amplified goodness. If the effort is not ethical, the amplified end product will be amplified badness or even evil. It seems like we […]

Plasmons Used in Optical Communications

When ripples in the fluid-like free electrons in conducting metals form oscillations, they can act like virtual particles and are called “plasmons”, a category of quasiparticles. Controlling plasmons which interact with light allows fast and efficient modulation of light based communications. What is a plasmon? – [nanoscale.blogspot.com] A plasmon is a collective excitation of the […]

Distributed Utilities

Distributed manufacturing is poised to change our world using 3D printing technology to manufacture objects locally. Our utility infrastructure can move in the same direction. Our basic needs are water, food, shelter, power, communications, and medical services. The basic utilities we consume most are water, electric power, communications networks. We are already seeing the beginning […]

Electronic Tattoos with NFC

Electronic skin and tattoos with embedded electronics can contain a variety of medical and health sensors as well as identification and authentication tools. Near Field Communications (NFC) is a short range (inches) induction based communication technology that uses RFID-like protocols to exchange credentials between devices. NFC can be used in simple form factors like smart […]

Time Reversal Signal Processing

Time reversal signal processing uses a mirroring technique to amplify and concentrate wave forms in specific mediums. When some forms of waves travel through some mediums, they can accumulate reflections that distort and diffuse the original signal. Think of an acoustic sonar ping under water bouncing off of every surface in a cluttered environment. The […]

Economics in Space

Before attempting to predict how commerce will occur in space or how government will be designed to regulate it, it is important to understand how the basic economic factors will be changed. Comparison of Economic Elements On Earth ELEMENT In Space free AIR expensive cheap WATER expensive moderate FOOD moderate expensive ENERGY cheap expensive TERRITORY […]

Exfiltrate data

There are several reasons why an attacker might want to get data back out of a system or network: Command and control communications Information collected about systems and network target data for future expansion Information that was the objective for penetration (identity theft, intellectual property) The process of getting the data out can be as […]
