Managing Credentials Committed to Git: Recovery and Prevention
Accidentally committed credentials to Git? Learn how to properly remove them, why git history rewriting isn't enough, and how to prevent future leaks.
Programming Paradigms: Choosing the Right Mental Model for Your Problem
Programming paradigms shape how we think about and solve problems. Understanding their strengths, trade-offs, and appropriate use cases leads to better software design decisions.
Identity Broker: Centralizing Authentication in Distributed Systems
Identity brokers centralize authentication across multiple systems, but implementation choices affect security, performance, and user experience. Understand the patterns, trade-offs, and pitfalls.
Dependency Inversion Principle: High-Level Modules Should Not Depend on Low-Level Modules
High-level modules should not depend on low-level modules. Both should depend on abstractions. This principle inverts traditional dependency structures, yet developers routinely create rigid architectures that violate it.
Interface Segregation Principle: No Client Should Be Forced to Depend on Unused Methods
Clients should not be forced to depend on interfaces they don't use. This principle prevents fat interfaces that burden implementers with unnecessary methods, yet developers routinely create bloated abstractions that violate it.
Liskov Substitution Principle: The Contract You Can't Break
Subtypes must be substitutable for their base types without breaking program correctness. This principle ensures inheritance hierarchies remain sound, yet developers routinely violate it with seemingly innocent design decisions.
Open-Closed Principle: Extending Without Breaking
Software entities should be open for extension but closed for modification. This principle promises flexibility without fragility, yet developers struggle with when to apply abstraction and when it becomes over-engineering.
Single Responsibility Principle: The Foundation of SOLID Design
A class should have only one reason to change. This simple statement forms the foundation of SOLID design, yet developers struggle with what constitutes a 'single responsibility' and when to split classes.
DRY Principle: When Code Duplication Becomes Technical Debt
Don't Repeat Yourself sounds simple, but knowing when to apply it requires judgment. Understand when duplication is harmful, when it's acceptable, and how premature abstraction can be worse than duplication.
Jenkins Credentials Exposure: The Hidden Security Risks in CI/CD Pipelines
Jenkins credentials can leak through build logs, script consoles, and API endpoints. Understand how credentials get exposed and how to protect your CI/CD pipeline.
