    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.

    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.
