- The Canon Cat uses Forth as a concatenative programming environment for subsystem scripting.
- Permacomputing focuses on maximizing hardware lifespan, minimizing energy usage, and utilizing existing computational resources.
- Designing for Disassembly ensures products can be easily repaired and components reclaimed, prolonging lifecycle.
- Frugal, Salvage, and Collapse Computing emphasize resource efficiency, reuse, and resilience in computing.
- Malleable systems support arbitrary recombination and are finely tuned by operators over time.
- Designing for reversibility lowers the cost of errors and makes systems approachable to various competency levels.
- Reversible computation examples include inverse operators and stack machine operations.
- Designing for concatenation uses point-free message passing for inspectability and performance.
- Designing for differences supports collaboration across different interfaces and competency levels.
- Designing for bootstrapping ensures systems can be built from minimal, inspectable binaries.
- Salvage computing celebrates the end of a product's lifecycle as an opportunity for reclamation.
- Techniques like Migration, Emulation, Encapsulation, and Universal Virtual Computer aid digital preservation.
- Collapse computing prepares for infrastructure collapse by prioritizing community needs and knowledge commons.
- Designing for Descent ensures resilience to intermittent energy and network connectivity.
- Kelvin versioning counts down to a final specification, freezing further updates upon reaching absolute zero.
- Four Concepts of Resilience: Agility, Preparedness, Elasticity, and Redundancy.
- Designing for decay hardens messages via error correction, like parity bits.
- The Arecibo Message's dimensions were chosen to be inferred without headers.
