If you run a small Public Housing Authority in East Texas — or sit on the board of one — you already know what the technology situation looks like. Somewhere on the property there’s a camera system that half works
Water Is Not Different: What Rural Infrastructure Engineering Is Actually Telling Us Right Now
When utilities, planners, and economic developers talk about water infrastructure, they tend to treat it as a permitting constraint — something to check off before the real planning work begins. You verify available supply, confirm treatment capacity, and move on to the site selection scorecard. Water is background.
OT CYBERSECURITY: What 2019 Engineering Practice Tells Us About 2026 Threats
The question for every OT operator reading this report is whether their current architecture gives them a fighting chance to detect lateral movement before it reaches the consequence-critical pathways, and to recover with confidence when it does. If the answer is uncertain, the path forward is to start with consequence mapping and build from there.
From Signals to Systems: Engineering as Stewardship
A specification tells you what a component should do under controlled conditions. It doesn’t tell you what happens when that component is asked to operate for twenty years in a substation control panel with inadequate ventilation, marginal grounding, and legacy protocols it was never designed to handle.
