WhiteSur GTK Theme
MacOS like theme for all gtk based desktops
WhiteSur-gtk-theme brings a macOS Big Sur–inspired look to Linux desktops by providing a polished GTK theme with light and dark variants, rounded shapes, and refined translucency. It includes assets and installer scripts to apply the theme across GTK applications and desktop shells that support GTK theming, aiming for a cohesive, high-contrast interface. The project pays attention to details like window controls, titlebars, selection states, and widget hover effects so apps feel consistent from toolkits to system settings. Configuration options typically allow tweaking accents and choosing variants that match different desktop environments and icon sets. Documentation guides users through installing prerequisites, applying the theme, and resolving common edge cases across distributions. For Linux users who prefer Apple’s visual style but want open platforms, WhiteSur offers a maintained, community-driven path to a modern, visually unified desktop. -

XLS
XLS: Accelerated HW Synthesis
XLS is an open-source toolkit for building high-level hardware with a modern compiler stack that spans from a functional DSL to optimized IR and hardware generation. At the front end, DSLX lets you describe algorithms with strong typing and familiar control flow while remaining synthesis-friendly. The compiler lowers DSLX into a rich intermediate representation, applies aggressive optimization and scheduling passes, and can either JIT the design for software simulation or emit Verilog for FPGA/ASIC flows. A key idea is “software-style” iteration: fast, deterministic simulation via the JIT encourages test-driven development and property checking before committing to RTL. XLS also provides tooling for pipelining, state insertion, and formal equivalence checks between different stages, giving developers confidence as designs evolve. The result is a productive path from high-level specification to real hardware, without giving up control over latency, throughput, and area trade-offs. -

System Design Primer
Learn how to design large-scale systems
System Design Primer is a curated, open source collection of resources that helps engineers learn how to design large-scale systems. The project is structured as a comprehensive guide covering core system design concepts, trade-offs, and patterns necessary for building scalable, reliable, and maintainable systems. It offers both theoretical foundations—such as scalability principles, the CAP theorem, and consistency models—and practical exercises, including real-world system design interview questions with sample solutions, diagrams, and code. 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. -

react-resizable-panels
React components for resizable panel groups/layouts
react-resizable-panels provides accessible, flexible split-view layouts for React without wrestling low-level pointer math yourself. It models layouts as “groups” of panels separated by resize handles, supporting horizontal or vertical orientation and mixed min/max constraints that prevent panels from collapsing unexpectedly. The library focuses on smooth interactions: dragging, double-clicking to reset, and keyboard resizing for users who rely on accessibility features. It also supports snapping, collapsed states, and layout persistence so your app can remember user preferences between sessions. Because the API is component-based, you can nest groups, render custom panel contents, and style handles to match your design system. Under the hood, it keeps measurement logic reliable across reflows and React 18 rendering patterns, making it suitable for IDE-like UIs, data dashboards, and inspector panes. -

We want to allow you to spend less time polishing mock-ups and more time polishing the product. First, we recommend reading the design workflow and development workflow guides. These capture our current views on how best to make use of Braid in your daily work. -

HyDE Linux
Aesthetic, dynamic and minimal dots for Arch hyprland
HyDE Linux is an aesthetic, dynamic and minimal dots for Arch hyprland. The installation script is designed for a minimal Arch Linux install, but may work on some Arch-based distros.
