Privacy Rights, Operational Data, and the US Government

in , , ,

Several readers have written me that privacy has no place in US Law, and was only discovered as an emanation from a penumbra (in Justice Douglas’s words). I think that this is a profound misreading of the constitution, arising from an awful ruling in a good cause in the 1870’s. The Slaughterhouse Case created a framework that profoundly limited the privileges of citizenship, gutting a key component of the 14th amendment, and by implication, eliminating the 9th amendment from any real meaning.

The 9th amendment, the shortest and simplest of the bill of rights...

General Relativity and Control Systems Standards

in , , , , , , ,

I suspect most of my readers can just about remember light speed, the 100 foot barn, and the 110 foot log from learning about relativity. The barn had doors at each end, and one set would close the instant the other doors opened. The challenge was to transport the log through the barn. The answer had to do with light speed and collapsing space, so that as one got close enough to light speed, the log shortened, and it could fit through the barn. It was a simple enough calculation as to how fast one could go to make the log shrink how much. When each of us had completed the math, the professor sprang the surprise on us: "OK, what is happening from the perspective of a cockroach on the log?"

IP Everywhere, or Just About

in , , , ,

In February, a new administration official stated that the smart grid requires "IP everywhere", stirring considerable concern among the dumbest (in terms of grid smarts) of the smart grid players. Earlier this month, as I wrote of in The Impulse to Run Around Naked, a maker of building systems asked why we don’t just build systems with their own native languages and their own "most optimal" media. The operators of the big distribution systems (SCADA) for electricity, water, sewage, and natural gas are all a-twitter over the proposed national cyber-security directorate. This agitation in those that manage the actions of the built world is based upon misunderstandings based upon poor definitions as much as anything else.

A Caffeinated view of Aging Energy Infrastructure

in , , ,

The local coffee shop, The OpenEye Cafe, has an outsized role in thinking about smart buildings and the smart grid. Each day when I leave the gym, I go to the OpenEye to caffeinate myself out of my post exercise torpor and to write.

The OpenEye is a great college town coffee shop, even if it is in Carrboro, the town next door to the college town. Its main room is huge for a coffee shop, fitted out with as many old couches and comfy chairs as it has little tables surrounded by mismatched chairs. It has numerous small side rooms, a patio in the back, more sidewalk seating in the front.

This size gives it a wonderful variety of subcultures, as there is the construction contractor corner, klatches of endurance runners, and every college town’s PWDIBs (people who dress in black). On weekends, the Men Who Run in Kilts...
