The big "above the fold" intro on a landing page: large heading, sub-copy, primary CTA, optional supporting image. Keep the H1 unique to the page and one per document.

Prepared Statement Reuse

For repeated queries (loops, bulk inserts), prepare once and re-use. The driver caches the parsed query and saves a round trip per invocation.

Kotlin

repeat, also lateinit and isInitialized

`repeat(n) { i -> ... }` for N-times loops where you don't care about index naming. `lateinit var` lets you declare a non-null var without initializing it — common for DI / framework injection.

Atomic Counter with flock

A single-file counter that survives concurrent increments correctly using flock + read-modify-write inside the locked region. Useful for crude visitor or job-id counters when you don't want a DB.

observable — Listen for Property Changes

`Delegates.observable(initial) { prop, old, new -> ... }` fires a callback every time the property changes. Useful for state-tracking, simple observability without a full reactive lib.

List Authors by Commit Count

Quick repo stats: who has done what. Add --no-merges if you don't want to count merge commits.

Substring + Find/Replace (parameter expansion)

Bash's ${var:offset:length} and ${var//pattern/replacement} let you do most string operations without ever spawning sed. Faster, and the syntax is portable across modern shells.

Rust

if let / while let

When you only care about one variant, `if let` is shorter than `match`. `while let` keeps looping as long as the pattern matches — great for draining iterators or option-returning APIs.

Uppercase / Lowercase / Title Case

Bash 4+ has built-in case conversion via parameter expansion. No need for `tr` or `awk` for most cases.

flag — Stdlib CLI Parser

The `flag` package is the minimal-dep CLI parser shipped with Go. Sufficient for many tools; reach for `spf13/cobra` or `urfave/cli` for subcommands and richer UX.

Run Command with Timeout

`timeout` (GNU coreutils) kills a command after N seconds. Returns exit code 124 on timeout — let the caller distinguish "timed out" from "failed for other reasons."

Pluck Column From Array of Rows

Extract a single column from a list of associative arrays into a flat list. Common transformation for SELECT results — equivalent to array_column with optional indexing key.

Truncate Text with Ellipsis (word-safe)

Cleanly truncate a string to a max length without breaking words mid-character. Adds a trailing ellipsis when truncated and never exceeds the requested length including the ellipsis.

pathlib Quick Reference

Forget os.path.* — pathlib.Path is the modern, OS-aware way to work with paths. Operator overloading for joins, attribute access for components, methods for reads/writes/iterations.

Word Count (UTF-8 aware)

Count words in a string in a way that works for any Unicode script — including those without ASCII whitespace. Built on the \p{L}\p{N} Unicode regex categories.

Stash With a Message

`git stash` without args is hard to grep through later. Always pass a message — your future self will thank you.

Squash Last N Commits

Combine the last N commits into one before merging a feature branch. Avoids hours of "WIP" / "fix typo" commits cluttering history.

Sealed Classes — Closed Type Hierarchies

`sealed` restricts subclassing to the same module. Combined with exhaustive `when`, the compiler enforces handling of every variant — refactor-friendly state machines.

rate.Limiter — Token-Bucket Rate Limiting

`golang.org/x/time/rate` provides a battle-tested token-bucket limiter. Use to enforce "N requests per second with bursts up to B" — for per-IP throttling, external API rate limits, etc.

Data Classes — Records Done Right

`data class` auto-generates `equals`, `hashCode`, `toString`, `copy`, and `componentN` (destructuring). Replaces boilerplate POJOs / Records / classes-with-lombok in one line.

Levenshtein Similarity Percentage

Wrap PHP's built-in levenshtein() to return a similarity score from 0.0 (totally different) to 1.0 (identical). Handy for "did you mean…?" suggestions.

Favicon Set (SVG + PNG fallbacks)

Modern favicon setup: one SVG that scales, an ICO fallback for old browsers, and an apple-touch-icon for iOS home screens. Skip the 12-file <link> dump from favicon generators of yore.

Simple State Machine

A lightweight finite state machine that defines valid states and allowed transitions between them. Attempting an invalid transition throws an error. Supports entry/exit hooks per state for side effects. Useful for modelling UI flows (idle → loading → success/error), auth states, and multi-step forms.

Scroll to Element Smoothly

Scrolls the page to a target element with an optional pixel offset (useful when a fixed header is present). Uses the native scrollIntoView with smooth behaviour when supported, and falls back to a manual scrollTo with a configurable offset. Pass a CSS selector string or an Element reference.

Long Polling Helper

Implements a long-polling loop that repeatedly calls a fetch endpoint and invokes a callback with the result. Backs off exponentially on errors and stops cleanly when cancelled via the returned stop function. A simple alternative to WebSockets for low-frequency server-push events without SSE support.
