    SkyWater PDK

    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

    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.

    GitHub Dark

    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.

    Zynga Scroller

    Zynga Scroller

    Accelerated panning and zooming for HTML and Canvas

    Scroller, also known as Zynga Scroller, is a pure JavaScript logic component for accelerated scrolling and zooming. It is independent of any rendering layer, which means it can power interactions for DOM elements, Canvas interfaces, or other custom rendering systems. The library handles panning, deceleration, bouncing, paging, snapping, zooming, directional locking, and pull-to-refresh behavior. It can be controlled manually through an API or used through EasyScroller, a simplified DOM-focused wrapper with data-attribute initialization. Developers can configure axes, animation behavior, zoom ranges, dimensions, and scroll targets. It is useful for web applications, games, visual tools, and custom interfaces that need smooth touch or mouse-driven navigation without relying entirely on native browser scrolling.

    ObjectBuilder2

    ObjectBuilder2

    C++ CASE tool, full life cycle code generator

    ObjectBuilder is a C++ code generation CASE tool (CASE, code generation, refactoring, documentation generation). It lets you create, manipulate and navigate classes, class relations, class members and class methods at a high level of abstraction. ObjectBuilder dramatically simplify work with C++ project architecture. I use it and think that tree OO interface targeted to C++ more fast and power than UML class diagrams. ObjectBuilder perfectly organize C++ header files with any level of complexity. Even if you use loop-references if OO hierarchy, you need include only one project-level header file. You can easy modify and refactore existing project with cut/copy/paste ANY object (from Method Argument to entire Project) within project and between ObjectBuilder projects. ObjectBuilder is not an IDE tool. It is portable two-way architect code-generation tool.
