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. -

vue-observe-visibility
Detect when an element is becoming visible or hidden on the page
vue-observe-visibility is a Vue plugin that detects when an element or component becomes visible or hidden in the browser viewport. It exposes the v-observe-visibility directive, which calls a user-defined function whenever visibility changes. The callback receives a Boolean visibility state and the corresponding IntersectionObserverEntry object. Developers can configure the observer root, root margin, and visibility threshold through standard Intersection Observer options. A once mode stops observation after the first visible event, making it useful for lazy loading and entrance animations. Throttling and leading-event controls reduce noisy updates during rapid scrolling. The observer can be disabled dynamically with a falsy directive value, while older browsers may require an Intersection Observer polyfill. -

Alabaster Theme
A light theme for Visual Studio Code
Alabaster is a light Visual Studio Code theme that intentionally minimizes syntax highlighting to keep code calm and readable. Instead of coloring every token category, it highlights just a small set of classes like strings, statically known constants, comments, and global definitions. Standard language keywords are deliberately left uncolored under the philosophy that they are obvious and draw unnecessary attention. This restraint produces a clean, low-noise editor surface that emphasizes what changes most during editing: names, literals, and commentary. The repository documents the rationale in detail and has inspired ports to other editors, showing its appeal to developers who prefer quiet aesthetics. Community discussions in the issue tracker revolve around targeted tweaks rather than expanding the palette, consistent with the theme’s minimalist vision.
