Idempotency Patterns
Make retries safe
Idempotency patterns store request ids or results to make retries safe, preventing duplicate side effects in APIs and jobs.

- side effects
Identify Side Effects
Find writes or external calls that could double-run.
Store Keys
Use idempotency keys to deduplicate and return the same result.
Test
Force retries/failures in tests to verify safe behavior.

API Basics
APIs let software request data or actions from other systems through defined endpoints and responses.
Comparison
RAM vs Storage
RAM handles what your device is actively working on, while storage keeps apps, files, and system data available over time.
How it works
Global Positioning System
GPS uses timing signals from satellites to calculate a receiver's position on Earth.
What it is
Blockchain
A blockchain is a distributed ledger secured by cryptography and consensus nodes.
