PYWAL
Generate and change color-schemes on the fly
PYWAL is a highly popular tool that automatically generates a color scheme from any image (usually your wallpaper) and then applies it across your Linux or Unix desktop. It analyzes the input image, extracts a palette, and builds theme files for terminals, window managers, and various desktop applications so everything looks coordinated. The magic is that it’s not just a one-off script: it supports many terminals, shells, and launchers, and can export the colors in multiple formats (JSON, Xresources, CSS) for other programs to consume. It also includes a set of predefined themes if you don’t want to generate from an image. Many users integrate PYWAL into their login or wallpaper-change workflows so the desktop “breathes” with whatever image they set. It’s lightweight, fast, and fits perfectly into the r/unixporn workflow of building cohesive, themed desktops. -

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. -

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. -

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. -

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. -

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. -
