FineTune
FineTune, a macOS menu bar app to control volume for each app
FineTune is a macOS menu bar application that gives users fine-grained control over system audio by allowing them to adjust volume levels for individual applications independently, route audio streams to different output devices, and apply personalized equalizer settings. It fills a gap in macOS audio control by providing more advanced routing and audio shaping capabilities than the default system controls, making it useful for power users, audio professionals, and anyone needing precise management of their sound environment. Through a clean, minimal interface accessible from the menu bar, FineTune lets users isolate and balance application volumes, assign specific outputs (like headphones versus speakers), and tweak equalization to enhance or tailor audio based on content or personal preference.

Styled Components
Visual primitives for the component age
Visual primitives for the component age. Use the best bits of ES6 and CSS to style your apps without stress. Utilising tagged template literals (a recent addition to JavaScript) and the power of CSS, styled-components allows you to write actual CSS code to style your components. It also removes the mapping between components and styles, using components as a low-level styling construct could not be easier! Alternatively, you may use style objects. This allows for easy porting of CSS from inline styles, while still supporting the more advanced styled-components capabilities like component selectors and media queries. styled-components is compatible with both React (for web) and React Native, meaning it's the perfect choice even for truly universal apps! If you're using tooling that has babel-plugin-macros set up, you can switch to the styled-components/macro import path instead to gain the effects of the babel plugin without further setup. -

The repository also contains study guides for short, medium, and long interview timelines, allowing learners to focus on both breadth and depth depending on their preparation needs. In addition, it includes flashcard decks designed to reinforce learning through spaced repetition, making it easier to retain key system design knowledge. -

With Lottie, you can achieve exquisite animations exactly how you want, with no additional engineering effort whatsoever. Take a look at the many beautiful animation possibilities available to you on http://airbnb.io/lottie/ -

98.css
A design system for building faithful recreations of old UIs
98.css is a CSS library for building interfaces that look like Windows 98. This library relies on the usage of semantic HTML. To make a button, you'll need to use a <button>. Input elements require labels. Icon buttons rely on aria-label. This page will guide you through that process, but accessibility is a primary goal of this project. You can override many of the styles of your elements while maintaining the appearance provided by this library. Need more padding on your buttons? Go for it. Need to add some color to your input labels? Be our guest. This library does not contain any JavaScript, it merely styles your HTML with some CSS. This means 98.css is compatible with your frontend framework of choice.
