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. -

Academic CV Theme
Easily create a beautiful academic résumé or educational website
theme-academic-cv is a Hugo static site theme specialized for building academic curriculum vitae (CV) websites, personal academic homepages, and scholarly portfolios. The theme is tailored to present publication lists, education, projects, awards, and contact information in a clean, professional layout suitable for faculty, researchers, and scientists. It includes shortcodes and content archetypes for common academic components (e.g. publications, talks, teaching, service), as well as styling, typography, and responsive layouts to make the CV visually appealing and readable across devices. The theme supports light/dark modes, custom color accents, and configuration options so users can modify the look without extensive CSS coding. It also often includes integration for BibTeX or publication metadata (e.g. rendering publication lists from bibliographic files) and support for linking PDFs, datasets, or supplemental materials. -

Figma Code Connect
A tool for connecting your design system components
Figma Code Connect is an open-source tool that enhances collaboration between designers and developers by synchronizing design components with source code in real time. Instead of treating design files and codebases as separate artifacts, it creates a continuous link so when a designer updates a UI element in Figma, developers see corresponding code changes or annotations immediately, making handoffs more precise and frictionless. The system supports multiple frameworks and languages, enabling teams to generate usable code snippets, style values, and component metadata from visual designs without manual translation. This approach reduces miscommunication and repetitive tasks that traditionally occur between design and engineering teams, speeding up iteration cycles while preserving fidelity to the original design intent. It can be integrated into development environments or build tooling so design updates automatically propagate into code patterns or UI specs. -

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. -

GNU Emacs / N Λ N O
Emacs made simple
GNU Emacs / N Λ N O is a lightweight, minimalistic Emacs-inspired text editor configuration (or “distribution”) created by Nicolas P. Rougier that aims to provide a simpler and more streamlined experience compared to full-blown Emacs setups. It retains essential editing capabilities while stripping down much of the complexity and heavyweight features that can make traditional Emacs intimidating to newcomers. The project includes only minimal configuration and essential extensions, enabling users to start editing text comfortably without wrestling with a steep learning curve or bloated init files. This makes it appealing for users who like the power of Emacs (or similar advanced editors) but want a fast, responsive, and easy-to-maintain editor. Nano-Emacs can be especially useful for scripting, quick edits, data-analysis workflows, or writing in scientific/research contexts, especially when you want something more powerful than a simple text editor but lighter than a full IDE. -

The theme includes multiple contrast levels—soft, medium, and hard—as well as light and dark variants to fit different lighting conditions. It supports true color, Treesitter highlighting, and plugin-specific integrations for a consistent UI. The color scheme aims to balance aesthetic warmth with functional legibility, making syntax stand out naturally without harsh saturation. With its thoughtful design, gruvbox-material has become a go-to for developers who want a cozy yet modern coding atmosphere. -

R Color Palettes
Comprehensive list of color palettes available in R
This repository is a curated collection of color palettes crafted or curated for data visualization in R. The goal is to provide designers, data scientists, and R users with aesthetically pleasing, perceptually consistent color schemes that work well for plots, maps, and graphics. The repo contains static files listing palette definitions (e.g. hex codes, named hues), sample visualizations showing how each palette performs under different contexts (categorical, sequential, diverging), and helper functions/scripts to import or use the palettes in R. The author also documents palette provenance and usage guidance (contrast, readability, colorblind friendliness). While not a full package in itself, it’s often used as a reference or source of palette definitions for other R plotting or theming packages. -

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. -
