The Ciphertext Outlives Its Key

Nine years ago I asked whether quantum computing would eventually kill Bitcoin. The same question, asked today about a national genetic database, has none of the qualities that made the original speculative.

  • The Commit Is the Deploy How a private Git repository, a deploy script, and encrypted secrets turned a multi-node homelab into infrastructure that scales without scaling complexity.
  • Two Nodes, One Lesson in Constraint From a four-node plan to a two-node reality. How energy costs, operational complexity, and data management shaped the compute layer.
  • The accountability satisfies the citizen, not the agent Agentic AI promises to transform government. But in a system built on explainability and open government, where every decision must be traceable and attributed, where does the agent end and the bureaucrat begin?
  • Building a Home Network You Actually Control Designing residential network infrastructure from scratch with architectural separation of concerns and principled infrastructure design.
  • The process you know but cannot describe Formalizing a process you know intimately but cannot articulate. A case study in process modelling using BPMN and the Italian Highway Code.
