SkyWater PDK
Open source process design kit for usage with SkyWater Technology
The SkyWater PDK is the first broadly available open-source process design kit for a commercial-grade CMOS node, enabling researchers, startups, and students to design real ASICs without proprietary NDAs. It provides the essential artifacts for digital and analog flows: SPICE models, DRC/LVS rules, extraction decks, and technology files for open tools like Magic and KLayout. Standard-cell libraries and IO pads are included so digital designers can use open synthesis and place-and-route to reach a manufacturable GDS. Because the PDK is open, it becomes a common target for community reference designs, open tapeouts, and teaching curricula. Documentation and example flows show how to assemble complete toolchains, from RTL to sign-off, using open EDA components. The project effectively lowers the barrier to custom silicon, catalyzing an ecosystem around an accessible 130-nm process. -

GitHub Dark
Dark GitHub style
GitHub-Dark is a userstyle that transforms GitHub’s interface into a coherent dark theme, covering repositories, issues, pull requests, gists, and profile pages. Distributed as a CSS stylesheet intended for the Stylus browser extension, it applies a comprehensive palette, rebalances contrast, and refines syntax colors for code views to ensure readability in low-light settings. The project goes beyond simple inversion by thoughtfully adjusting backgrounds, borders, badges, and diff highlights so the UI feels native rather than “flipped.” It includes targeted fixes for edge cases across GitHub’s many subpages, aiming for consistency while preserving the information hierarchy of the original design. Users can apply the theme selectively, override variables, or combine it with other userstyles to fit personal preference. Even with GitHub’s own theme options, GitHub-Dark remains a carefully tuned alternative for people who want a specific aesthetic or more granular control. -

Guides
Design and development guides
This repository is a curated collection of links and resources aimed at helping programmers improve their craft, especially with regard to coding style, design practices, development workflows, and engineering discipline. The idea is that instead of reinventing style guides or best-practices from scratch, developers can reference this repository for high-quality external guides, articles, and checklists across many languages and ecosystems. It is not a library in the usual sense, but acts as a “meta-guide” index — a directory of authoritative resources rather than runnable code. The content is organized as Markdown links and descriptions, making it easy to scan and browse for relevant topics (for instance style guides for Ruby, JavaScript, CSS, deployment, architecture). Because it is community-driven and open to contributions, you’ll find new links and categories being added over time, helping it remain relevant. -

SignalCommandMap
Robotlegs extension to facilitate the use of AS3-Signals with Robotleg
signals-extensions-CommandSignal is an ActionScript 3 extension that integrates Robotlegs and AS3-Signals frameworks to provide a cleaner, strongly typed alternative to traditional Flash Events in application architecture. Robotlegs uses events as the communication mechanism between models, services, and commands, but this project replaces that system with the more robust and object-oriented AS3-Signals. By combining the two, developers can eliminate the ambiguity and string-based event registration common in standard event-driven patterns. The library introduces the SignalCommandMap, a utility that allows developers to map Signals to Commands, enabling commands to trigger automatically when a Signal’s dispatch() method is called. This extension also creates a SignalContext, an enhanced MVCS context that manages Signals alongside the traditional Robotlegs maps. -
