    Cmockery

    Cmockery

    A lightweight library to simplify and generalize writing unit tests

    ...It allows developers to test the logic of C modules in isolation by replacing external dependencies with mock functions. Cmockery focuses on testing functionality rather than environment-specific behavior, making it ideal for projects where code must run on diverse or constrained systems. Unlike many modern frameworks, Cmockery is compatible with older compilers and avoids dependencies on newer C language features, making it suitable for legacy codebases or embedded development.

    Django REST Pandas

    Django REST Pandas

    Serves up Pandas dataframes via the Django REST Framework

    ...This keeps the implementation simple, but also has the nice side effect of making it trivial to provide the source data for your visualizations. This capability can often be leveraged by sending users to the same URL that your visualization code uses internally to load the data. While DRP is primarily a data API, it also provides a default collection of interactive visualizations through the @wq/chart library, and a @wq/pandas loader to facilitate custom JavaScript charts that work well with CSV output served by DRP. These can be used to create interactive time series, scatter, and box plot charts.

    Text Typesetting

    Concise guide to better typography and formatting practices

    Text-Typesetting is a concise guide to better typography and formatting practices for technical writing. It collects rules of spacing, punctuation, emphasis, and layout that improve readability, especially in documents mixing multiple languages or code. The repository focuses on consistent micro-typography—such as when to use non-breaking spaces, how to place punctuation around quotes, and how to format lists and headings. Examples show the before/after impact of small adjustments, making the guidance practical rather than theoretical. Because the recommendations are tooling-agnostic, they apply to Markdown, HTML, slides, and printed PDFs alike. ...

    Go Meta Linter

    Runs a whole bunch of those linters and normalizes their output

    ...It normalizes their results into one consistent output format so editors, IDEs, and CI systems can read problems more easily. The tool helps developers catch issues such as unused code, unchecked errors, duplicated code, style problems, security concerns, and suspicious compiler-level behavior. It supports a broad collection of linters and lets users customize which checks run for each project. It can also be configured through a JSON file, which makes it easier to share linting rules across a team. Although the project is archived and users are directed toward golangci-lint, it remains a useful example of early Go lint aggregation.

    angularjs-style-guide

    angularjs-style-guide

    Community-driven set of best practices for AngularJS application

    ...It codifies directory structure, naming conventions, module organization, controllers, directives, services, templates, routing, testing, and other AngularJS-specific patterns — offering a consistent baseline for teams working on medium- to large-scale AngularJS apps. By prescribing such conventions, the guide helps improve code readability, maintainability, testability, and project scalability, reducing “spaghetti code” or inconsistent patterns across contributors. The style guide does not try to cover generic JavaScript style (which are left to standard JS style guides), but focuses on AngularJS-specific idioms and practices, making it highly relevant for any AngularJS codebase.
