      4. vector
      5. span
      6. unordered_map
      7. function
  8. How To's
    1. Filesystem
      1. Files (create / read / write / delete)
      2. Directories (create / rename / move / copy / delete)
      3. Paths & metadata (exists, size, timestamps)
    3. Networking
      1. HTTP client — GET / POST
      2. HTTP server — handle GET / POST routes
      3. TCP / UDP basics
    5. Error handling
      1. Idiomatic result / error propagation
      2. Panic / recover / stack traces
    7. Concurrency & async
      1. Threads & joining
      2. Async/await and event loop
      3. Channels / message passing
    9. Processes & OS integration
      1. Spawn subprocess, capture stdout/stderr
      2. Env vars, CLI args, signals (graceful shutdown)
    11. IO & streams
      1. Buffered vs streaming IO (large files, backpressure)
      2. Memory-mapped files & streaming reads
    13. Data handling & serialization
      1. JSON ↔ typed structs
      2. CSV and binary parse/write
    15. Testing & CI
      1. Unit tests & assertions
      2. Integration tests (spawn process, network)
      3. Running tests in CI / coverage basics
    17. Tooling & IDE
      1. Build / run / flags / release builds
      2. Formatter, linter, debugger, VS Code setup
    19. Security & crypto
      1. TLS/HTTPS (client + server) best practices
      2. Secrets management & safe randomness
    21. Packaging & deployment
      1. Build a distributable binary, embed assets
      2. Docker image and cross-compile notes
    23. FFI & interop
      1. Call C (FFI) and ownership rules
      2. Expose functions for C callers
