Kotlin
ViewModel + StateFlow + Compose
Standard Android pattern: ViewModel holds state in a `StateFlow`, Compose collects it as state. Survives config changes; isolates business logic from UI.

Tail Logs from Multiple Containers
`docker compose logs -f` already does this — but the one-liner with --tail and filters is the more useful day-to-day workflow when you only care about recent activity from a subset of services.
Kotlin
Jetpack Compose — Basic Composable
Compose is Android's modern declarative UI toolkit. A `@Composable` function describes UI; the runtime re-runs it when inputs change. Replaces XML layouts entirely.
Kotlin
Compose LaunchedEffect — Side Effects
`LaunchedEffect(key)` runs a coroutine when the key changes. Use for one-shot init, snapshot listening, data loading, or any suspend work tied to a composition.
JavaScript
Pipe & Compose
pipe applies a list of functions left-to-right (first function runs first), while compose applies them right-to-left. Both pass the result of each step as input to the next. Fundamental building blocks for functional programming in JavaScript — build data transformation pipelines without intermediate variables.
Kotlin
Compose State Hoisting
Lift state UP to where it's needed. A composable becomes "stateless" (taking `value` + `onValueChange`) which makes it reusable and testable. The Compose mantra.
Kotlin
Compose Layout: Column, Row, Box
Compose's three fundamental layouts. `Column` stacks vertically, `Row` horizontally, `Box` overlays. Combine with `Modifier.weight()`, alignment, and arrangement for flexible UIs.
