D (Programming Language) features and specs

  • Performance
    D is designed to be a high-performance systems programming language, offering performance comparable to C and C++ through native machine code compilation.
  • Expressiveness
    D features a rich standard library and modern language constructs, such as garbage collection, first-class arrays, and advanced templating, making it easier to write expressive and maintainable code.
  • Memory Safety
    D offers optional garbage collection along with manual memory management. This hybrid approach can help in developing safer applications by reducing memory-related errors.
  • Interoperability
    D can easily interoperate with C API, enabling seamless integration with existing C libraries and systems. It also supports better C++ interoperability compared to other languages.
  • Built-in Unit Testing
    D has built-in support for unit tests, allowing developers to write and run tests as part of the language itself, facilitating test-driven development.
  • Concurrency
    D offers built-in concurrency support with message passing, similar to the actor model found in languages like Erlang, making it easier to write concurrent and parallel programs.

Possible disadvantages of D (Programming Language)

  • Adoption
    D is not as widely adopted as other languages like C, C++, or Java. This limited adoption means fewer libraries, frameworks, and community support.
  • Toolchain Maturity
    While D's compilers and tools have improved over the years, they may still lack the maturity and feature set of more established languages, which can affect developer productivity.
  • Learning Curve
    D's richness and combination of paradigms (such as imperative, object-oriented, and functional programming) can present a steep learning curve for new developers.
  • Garbage Collection
    Although D offers optional garbage collection, its reliance on it for memory safety might be seen as a drawback for real-time system development where deterministic memory management is crucial.
  • Ecosystem
    The ecosystem for D is less vibrant compared to more popular languages, leading to potentially fewer third-party libraries, tools, and resources.
  • Standard Library Documentation
    The standard library documentation can be inconsistent or less comprehensive compared to other languages, making it difficult for developers to fully utilize all features of the language.

FitSW features and specs

  • Comprehensive Client Management
    FitSW provides a robust client management system that allows personal trainers to track client progress, manage workout routines, and monitor nutrition plans in one central location.
  • Customizable Workout Plans
    Trainers can create, save, and customize workout plans for their clients. This flexibility ensures that each workout can be tailored to the client's goals.
  • Progress Tracking
    The platform supports detailed progress tracking, enabling trainers and clients to monitor improvements over time in various metrics, such as weight, reps, and body measurements.
  • Mobile Accessibility
    FitSW offers mobile apps for both iOS and Android devices, providing convenience for trainers and clients who are on the go.
  • Integration with Other Tools
    It integrates with popular fitness tools and devices, such as MyFitnessPal and Fitbit, which can enhance the tracking and planning capabilities.

Possible disadvantages of FitSW

  • Learning Curve
    New users might find the range of features overwhelming at first, requiring a significant amount of time to become familiar with all the functionalities.
  • Price Point
    Some users might find the pricing to be on the higher side, especially new trainers or small businesses working with a tight budget.
  • Limited Customization Options
    While workout plans can be customized, some users have reported that the layout and user interface offer limited customization, which could hinder personalization.
  • Occasional Performance Issues
    Some users have experienced occasional performance issues, such as slow load times or bugs, which can disrupt the user experience.
  • Client-Specific Features
    Though feature-rich for trainers, there are fewer options focused on the client side, potentially limiting client engagement beyond what the trainer provides.

    I've spent 2 weeks (2-4h per day) to make D language[1] version of Sciter SDK [2] Choice of AI "tooling" was by accident - typed something like "how to define copy constructor in D for custom structure" in Microsoft's Copilot in Edge browser that gives context for AI.

    > Mostly, I am not really trying to compete with C/C++/Rust on speed, but I'm not going to add a GC either. So I'm somewhere in there.
