    HighwayHash

    HighwayHash

    Fast strong hash functions: SipHash/HighwayHash

    ...It’s designed to defeat hash-flooding attacks by mixing input with wide SIMD operations and a branch-free inner loop, so adversaries can’t cheaply craft many colliding keys. The implementation targets multiple CPU families with vectorized code paths while keeping a portable fallback, yielding high throughput across platforms. It exposes simple one-shot and streaming APIs, so you can hash short keys or long byte streams with the same function. Typical uses include protecting hash tables that store untrusted keys and authenticating short-lived messages or records in storage systems. ...

    reCAPTCHA

    reCAPTCHA

    PHP client library for reCAPTCHA, a free service

    ...Its design philosophy is “risk-based”: most users pass silently based on behavioral signals, while higher-risk interactions may be challenged with an image, checkbox, or other verification step. Site owners register keys, embed a small client script, and verify tokens on the server to protect actions like sign-ups, logins, and form submissions. The ecosystem supports mobile and enterprise variants, but the repo focuses on common web integrations and best practices for verifying the token securely. Deployed correctly, reCAPTCHA reduces credential stuffing, bot sign-ups, and scraping without degrading the experience for typical users.

    The myclabs/php-enum library is a PHP package that provides an object-oriented approach to implementing enumerations, inspired by the SPL's SplEnum. Before PHP 8.1 introduced native enum support, this library offered a structured way to define and use enumerated types, enhancing code readability and type safety. By extending the base Enum class, developers can create enums with defined constants, ensuring that variables only hold valid, predefined values. This approach helps prevent errors...

    react-error-boundary

    react-error-boundary

    Simple reusable React error boundary component

    ...It wraps React’s error-handling primitives in a single <ErrorBoundary> component with a predictable API for rendering fallbacks when descendant components throw during render, lifecycle, or event handlers. The library emphasizes recovery, not just failure: you can reset the error state programmatically or when certain “reset keys” change, returning the subtree to a healthy state without a full page refresh. It supports both declarative fallbacks (elements) and a render-prop approach so you can tailor the UI to the error and provide retry buttons or diagnostics. Callbacks make it easy to log errors to your own telemetry, show toasts, or trigger side effects when boundaries trip or reset. ...

    An idiomatic clojure http client wrapping the apache client

    ...Rather than forcing all request headers to be lowercase strings, clj-http allows strings or keywords of any case. Keywords will be transformed into their canonical representation, so the :content-md5 header will be sent to the server as “Content-MD5”, for instance. String keys in request headers, however, will be sent to the server with their casing unchanged.

The library includes recipes and examples that show how to handle different naming conventions like PascalCase, camelCase, snake_case, and kebab-case by normalizing separators. It also offers control over diacritics handling, allowing you to strip or keep accents depending on the UX you want. ...

    Classnames

    A simple javascript utility for conditionally joining classNames

    ...Instead of manually concatenating strings, developers can pass any combination of strings, arrays, or objects, and the library will output a clean, space-separated class list. When you provide an object, the keys represent class names and the boolean values determine whether each class should be included in the final string. This reduces boilerplate and the risk of typos or stray spaces, especially in React, Vue, or other component-based UIs where dynamic styling is common. The utility is small and framework-agnostic, so it can be used in Node, browser code, or any bundler setup including Browserify and Webpack. ...
