Ideas worth keeping
Practical guides to the systems behind reuse, memory, and discovery.
Explore ten complete articles across cache foundations, AI and agents, the browser, search discovery, and engineering. Each one starts with a specific question and follows it through examples, tradeoffs, and a primary source you can inspect.
Read a single guide for a focused answer, or follow the categories to connect the ideas. The articles are listed from newest to oldest, with their publication dates and related topics kept visible.
A similar question can still require a different answer. Learn which changes invalidate semantic cache entries and how to migrate without silently reusing incompatible results.

A search results screenshot is only the beginning. Build an observation workflow that preserves context and distinguishes real changes from capture differences.

A cache-hit percentage is only useful when its denominator is clear. Learn how to reconcile token reuse, request counts, and task cost.

A useful cache API needs more than get and set. Define identity, freshness, generations, and failure behavior so clients know when a response is safe to reuse.

A remembered preference, an active task, and a reusable answer need different rules for identity, updates, retention, and evaluation.

Build a clear AI search measurement plan: define visibility, preserve answer context, review content, and keep cached observations separate from ranking claims.

A stable prompt prefix can make repeated context reusable. The benefit depends on useful repetition, careful versioning, and measured behavior.

An indexed URL, a reusable response, and a saved page answer different questions. Learn how to distinguish them and investigate stale content with useful evidence.

Follow one resource from its first download to a cache hit, a validation request, and an update—and learn which browser cache is involved.

A cache index helps a system decide which stored result belongs to a request—and whether reusing it is still appropriate.
