Anti-Fragile Systems

Note systems survive app shutdowns when built on plain files, open formats, and tested backups.

Key Concept

• Note systems that survive app shutdowns - plain files, open formats, and backups I actually test.
• Level 1: Like when you save your drawing as a plain picture file - any computer can open it even if one app dies.
• Level 2: A diary written in pencil beats a diary locked inside one fancy app - open formats survive when the company shuts down.
• Level 3: Anti-fragile note systems survive app shutdowns because plain files and tested backups any tool can read outlast vendor lock-in.
• Level 4: Export to plain text or markdown quarterly and open the backup file once - if you cannot read it, the system is not anti-fragile yet.
• Level 5: Boring files beat tool-coupled structure when vendors change terms - ties to Future-Proofing Knowledge and Antifragility; close calls are stress signals before the system breaks for real.
• I build on plain files and open formats so an app shutdown does not erase years of notes.
• Test backups while the app still works - not after the export dies.

Examples

• When the gym's booking app shut down for good, my paper training log still had every set - I photocopy it once a quarter so I am not rebuilding history from memory.
• The shop switched POS systems twice and the owner kept a plain spreadsheet backup - exports she actually opens, not trust in the vendor forever.
