Postgres is the source of truth, while markdown remains the portable import and export format.
#starter-collection
Ideas connected by the same working tag.
These are ready for open discovery, ranking, and topic pages.
Shared workspaces sit between personal notes and the public commons.
Obsidian-style notes, but social
Each idea is a portable note with backlinks, tags, frontmatter, and visibility controls. The feed below is generated from the database-backed vault graph.
The map is not the territory
A useful model leaves things out. The question is whether it leaves out something that matters for your decision.
The problem of induction
Past patterns help us predict the future, but past success alone cannot logically guarantee that a pattern will continue.
Falsifiability and its limits
A claim becomes easier to investigate when you can say what evidence would count against it.
The veil of ignorance
Design a rule without knowing which position you will occupy under it. What would you protect?
The ship of Theseus
If every plank in a ship is replaced, what makes it the same ship: its matter, form, history, or something else?
The is-ought gap
Facts help us choose how to act, but a recommendation also needs a value or goal.
Feedback loops and stability
A system can respond to its own output. Whether that response dampens or amplifies change shapes what happens next.
Entropy and open systems
Local order can increase while total entropy increases. The boundary around the system matters.
Evolution has no foresight
Natural selection can produce adaptation without planning for a future goal.
Emergence from local rules
Simple interactions among parts can produce patterns that are easier to describe at the level of the whole.
Correlation is not causation
Two things moving together is a clue. It does not tell you which intervention would change the outcome.
Uncertainty is part of measurement
A measurement is more useful when it states how uncertain it is and where that uncertainty comes from.
Bayes rule and belief updates
Evidence changes belief through both how expected it was and how plausible the hypothesis was beforehand.
Small world networks
A few long-range links can connect tight local clusters without erasing their local structure.
Godel and the limits of proof
A consistent, effectively axiomatized theory rich enough for arithmetic cannot settle every arithmetic statement.
Infinity comes in sizes
The whole numbers and real numbers are both infinite, but there is no one-to-one pairing between them.
Symmetry and conservation
Under the conditions of Noether's theorem, a continuous symmetry of a physical action yields a conserved quantity.
Exponential growth and doubling
When growth is proportional to the current amount, equal time steps multiply the total rather than add a fixed amount.
