JavaScript
Serialize Form to Object
Converts all named form fields into a plain JavaScript object using the FormData API. Handles text inputs, selects, textareas, and checkboxes. Multiple values for the same name (e.g. multi-select, checkboxes) are collected into an array. Ready to JSON.stringify and POST to an API.

Cookie Helpers (Get / Set / Delete)
Minimal cookie utilities: getCookie retrieves a value by name, setCookie writes a cookie with optional expiry days and path, deleteCookie removes it by setting an expired date. No library needed for simple first-party cookie management. For complex scenarios (SameSite, Secure, partitioned) extend the options object.
JavaScript
Middleware Pipeline
A simple Koa/Express-style middleware runner for client-side use. Middleware functions receive a context object and a next() function — call next() to pass control to the next middleware or skip it to short-circuit the chain. Useful for building plugin systems, request pipelines, and composable validation logic.
JavaScript
Flatten Object (Dot Notation)
Flattens a deeply nested object into a single-level object with dot-notation keys. Useful for comparing configs, building form field names from nested data, logging structured objects to analytics, or preparing data for flat key-value stores like Redis or environment variables.
JavaScript
i18n Minimal Translator
A tiny internationalisation helper that loads a locale dictionary and resolves translation strings by dot-notation key. Supports variable interpolation via {{placeholder}} syntax. Falls back to the key itself when a translation is missing, keeping the UI readable during development. Swap the locale at runtime without a page reload.
PHP
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.
Go
JSON Marshal / Unmarshal
`encoding/json` is the standard library JSON parser. `Marshal` produces compact JSON; `MarshalIndent` produces pretty-printed. `Unmarshal` decodes into a typed value (struct, map, or any).
PHP
Email Address Obfuscator
Render an email address as HTML that is human-readable but resistant to naive scraping bots. Uses entity encoding and an optional Caesar-style ROT for the mailto link.
Rust
unsafe — When and How
Most Rust is safe. `unsafe` only lets you do 5 things the compiler can't check (raw pointer deref, mutable static, unsafe fn / trait, FFI, union access). Wrap unsafe operations in safe abstractions.
PHP
Convert Camel Case ↔ Snake Case
Convert between camelCase and snake_case identifiers. Handy when mapping JS API responses (camelCase) into PHP database column names (snake_case) and vice versa.
Kotlin
init Block + Constructor Order
`init { }` blocks run during construction, in declaration order, interleaved with property initializers. Use to validate the primary constructor or set up derived state.
HTML
Textarea with Character Counter
Combine `maxlength` (hard cap) with a small JS-driven live counter. Browsers won't let users paste past `maxlength`, so this is purely UX feedback.
PHP
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.
HTML
RTL (Right-to-Left) Document
Set `dir="rtl"` on the root element for languages that read right-to-left (Arabic, Hebrew, Persian). The browser flips text alignment, scroll, and form controls automatically. Use `dir="auto"` to let user-generated text decide per-block.
Bash
Run on Multiple Hosts via SSH (with progress)
Iterate a host list, run the same command on each, show colored OK/FAIL summary at the end. Useful for ad-hoc fleet operations without setting up Ansible.
Python
Producer / Consumer Queue (threading)
Classic producer / multi-consumer pattern using queue.Queue. Producers put work onto the queue; consumers pull and process; a sentinel value signals shutdown.
PHP
Secure Session Bootstrap
Start a session with all the security flags you should always set: HttpOnly, SameSite=Strict, Secure on HTTPS, custom name, and an idle-timeout regeneration.
