“The Code You Never Chose” — “Born Free, Programmed Fast”
- From the moment you were born, your mind was open to external influences, shaping your beliefs and perceptions without your choice.
- The societal programming ingrained in you from childhood restricted your ability to think freely and question the norms imposed by authority figures.
- Repetition, emotion, and authority were used to install beliefs that now dictate your choices and actions, keeping you confined within invisible walls of limitation.
- However, there is a possibility to break free from this programmed mindset by questioning inherited beliefs, unlearning false truths, and taking control to rewrite your own narrative.

Building Solo: Errors
- When developing alone, implementing error handling can be challenging, especially with separate backend and frontend setups.
- Having a clear plan for error management can make it convenient for both the backend and frontend.
- Implementing an enum on the backend to indicate error types can simplify error handling without relying solely on status codes or messages.
- FastAPI allows for a structured error architecture using exception handlers to manage various error types.
- Mapping error types to specific classes with messages and information can enhance error handling and reduce boilerplate code.
- On the frontend (NextJS), defining error types and using classes to handle errors can streamline the error processing from the backend.
- Errors are categorized as common or action-based, allowing users to take appropriate actions for different error scenarios.
- Error types are mapped to corresponding UI classes using a factory pattern for efficient error handling and presentation.
- The error-handling architecture offers a good balance between structure, flexibility, and user experience for solo developers or small teams.
- Pros include clear error typing, frontend ownership of UX, extensibility with OOP, and centralized backend handling.

RBAC vs ABAC: Picking Your Access Control Fighter
- RBAC (Role-Based Access Control) and ABAC (Attribute-Based Access Control) are two different access control strategies that organizations can choose from.
- RBAC assigns permissions to roles and users gain access through these assigned roles, ideal for simpler and fixed organizational structures.
- ABAC determines access based on evaluating multiple attributes such as user details, resource being accessed, action being taken, and environmental factors.
- Choosing between RBAC and ABAC depends on the complexity of access requirements and organizational structure, with hybrid models increasingly being used for best results.

Why Learning to Code in 2025 Feels Like Cheating
- The new generation of self-proclaimed developers rely heavily on AI tools like Cursor, Copilot, and ChatGPT for coding, rather than developing true computer science skills.
- AI is being used as a crutch rather than a power tool, as these developers struggle with basic tasks like debugging without external assistance.
- The emphasis is on learning how to structure and plan code, solving actual problems, rather than just relying on AI to assemble code snippets.
- Ultimately, the decision lies in whether these developers will choose to depend solely on AI or build their coding skills to succeed when faced with real challenges.
