Cases when Ruby does not work

1. Ruby is not suitable for high-performance computing tasks due to its slower execution speed compared to other languages like C++ or Java. In situations where speed is critical, such as intensive numerical calculations or real-time systems, Ruby may not be the best choice.
2. When developing mobile applications, Ruby may not be the ideal language. While there are frameworks like RubyMotion that allow for mobile app development using Ruby, they are not as widely adopted or supported as native development languages like Swift for iOS or Java/Kotlin for Android.
3. If you are working on a project that requires low-level system programming or interacting directly with hardware, Ruby may not be the most suitable choice. Languages like C or Rust are better suited for tasks that require fine-grained control over memory and low-level operations.
4. Ruby may not be the best choice for projects that heavily rely on parallel processing or multi-threading. While Ruby does support multi-threading, its Global Interpreter Lock (GIL) can limit the effectiveness of utilizing multiple cores or processors for concurrent execution. Languages like Python or Go provide better support for parallelism.
5. When working with large amounts of data or Big Data processing, Ruby may not be the most efficient option. Languages like Python or Scala, along with their respective ecosystems (Pandas, Spark), are commonly used for data analysis and processing tasks due to their optimized libraries and frameworks.
6. In environments where memory usage is a critical factor, Ruby may not be the most efficient language. Ruby’s memory footprint is relatively larger compared to languages like C or Go. This can limit its suitability for resource-constrained systems or applications that require efficient memory utilization.
