General Design

Safe designs employ strong-versatile materials to withstand edge cases, pre-failure signals to alert users, prevention-interruption mechanisms to avoid/stop cascading failure, designed-failure points to prevent catastrophic failure.

Example: Material. Metal gears last a long time. Weak plastic gears can strip under high torque, crack when cold, and warp when hot.

Example: Signal. Smoke alarms beep on low battery. Hard drives slow down before they fail. Car dashboards show engine problems.

Example: Prevention-Interruption. Circuit breakers shut down the main electrical connection when high current is detected. Lock-out Tag-out procedures prevent people from turning on equipment when someone is working inside it.

Example: Designed Failure Points. Car crumple zones are designed to break and absorb the impact force of a crash, destroying the car but saving the passengers.

Data Protection

Secure your files, papers, and accounts against edge cases and catastrophic failures. Common data in need of protection include your phone contacts, password lists, and legal records. To protect against concussions and memory lapses, write down your master password on a physical medium and store it somewhere exceptionally safe.

Portable Backup: Prepare an encrypted USB drive with the core information you would need in case of a home fire or robbery. Attach the USB drive to your keychain and carry it wherever you go.

High-Capacity Backups: Prepare a general SSD and encrypted SSD with normal and sensitive information accordingly. This protects you from hard drive failure/corruption on your computer and its potentially irrecoverable data loss.
