How can you design software systems that handle bugs and avoid crashes?

Bugs are not necessarily technical issues, bugs are sometimes a deviation from the exact requirements of a software. So, clarifying requirements is the first step to avoiding bugs. Also, testing codes before merging them, helps to clarify the functionality of the software against the requirements. I also recommend comprehensive logging. When logging, a log should be made with a log identifier. This log identifier helps to trace the logs and it's easy to know where the code broke. Also, Exception handling helps the software to fail safely instead of crashing. Most times, in Software, I advise global exception handling, so that even if a new engineer forgets to put a local exception handler, the global one can pick it.

Define the requirements first before doing any thing can avoid enormous bugs in future, not all coding bugs or memory leaks, could be logical bugs.

Be meticulous in handling bugs. Make sure that no information is left behind. Faults can happen however, make it to a minimum.

Understanding the importance of clear and realistic requirements is pivotal in software design. Defining both functional and non-functional aspects of the system sets a solid foundation for development. This involves identifying expected inputs, outputs, behaviors, performance, security, and usability criteria. Testing and validation ensure that the software meets these requirements, minimizing ambiguity, inconsistency, and incompleteness in the design process. It's about establishing a strong baseline to prevent bugs and crashes later on.

A few points to add/address: - Flexibility in Tool Selection: Prioritize tools and technologies with a wide community support and flexibility to switch or integrate with other technologies as needed. - Assess Suitability and Maturity: Evaluate the technology's maturity and its community support, not just its popularity, to ensure it meets the project's long-term needs. - Plan for Learning and Adaptation: Allocate time and resources for team training and gradual adoption of new tools or methods to mitigate the impact on project timelines. - Simplicity as a Principle: Consider the simplest tool or method that effectively meets the requirements, reducing complexity and future maintenance efforts.

Error Handling involves writing code that anticipates and gracefully handles potential errors or exceptional conditions that may occurs during the execution of your software. Logging can capture various levels of information ,such as debug messages ,information messages warnings ,and errors.

Make sure that you take error handling and exception handling seriously. This can help in making sure that there are no crashes.

transparencia para el desarrollo La implementacion del control y registro de errores se recomienda sea lo mas transparente para el codigo de negocio y buscar en lo posible transparencia entre el control y el negocio

Using try catch to avoid unknown crash reasons cannlead to mad consequences, use it carefully especially if the application is a server or at high demand.

Along with the programming language exception handling mechanism other techniques such as the Retry pattern as very useful, especially when using protocols with no guarantee of delivery. Transitory network errors can happen, unavailability of the application or even partial failures. A good example is using a web client configured with Retry(ies) where when a request is not responded to at a certain amount of time (timeout) the client retries the request automatically to overcome the transitory issue.

Function testing is firsto to try then module or unit test , if you working on one module you stop here and you should know that your module meets all cases conditions without problems

Testing and debugging are like guardians for your system's health. Through methods like unit and integration testing, they confirm your system meets expectations. Debugging, with tools like breakpoints, safeguards against errors, ensuring your system is correct, functional, and user-friendly.

Perder el miedo es bueno perder el miedo a crear pruebas unitarias y ejecutarlas con cada cambio eso ayuda y agiliza el desarrolloy los cambios principalmente. y si es mas codigo pero menos errores

estado actual hoy las soluciones tecnologicas son conjuntos de aplicaciones que interactuan entre nuevas y legado es bueno las nuevas aplicar las mejores practicas y en las antiguas si es posible modernizar para mejorar las practicas sin olvidar que cada caso es particular
