Randomness - Wikipedia

Randomness is the lack of definite patterns or predictability in information, applicable across mathematics, physics, biology, and statistics where individual events are unpredictable but follow known probability distributions. The concept has evolved from ancient divination practices through rigorous mathematical formalization in the 16th-20th centuries, becoming essential to modern computational science and various practical applications. Common misconceptions about randomness include the gambler's fallacy and the belief that past outcomes influence future ones in truly random processes.

MCP

Five tools over MCP: capture, annotate, search, rewatch, get-snapshot. Scoped API keys at /settings/mcp-keys.

Storage

Permanent S3 Snapshots
