Ugly Unit Tests - A Collection of Testing Horrors
From test-everything monsters to sleep-and-pray approaches, explore real-world testing nightmares and learn how to write maintainable tests that actually give you confidence.
Decoding Digital Anomalies
Sometimes the feature is the bug in the digital rabbit hole, and vice versa
From test-everything monsters to sleep-and-pray approaches, explore real-world testing nightmares and learn how to write maintainable tests that actually give you confidence.
Understand the fundamental differences between git merge and git rebase, learn when to use each approach, and master the techniques that keep your Git history clean and meaningful.
Master semantic versioning to communicate changes clearly and manage dependencies reliably. Learn the MAJOR.MINOR.PATCH format, pre-release identifiers, and how to implement SemVer in your development workflow.
Database backups aren't just SQL dumps. Learn how to design robust database backup strategies that ensure consistency, minimize downtime, and protect against data corruptionābefore disaster strikes.
Backups aren't just about copying files. Learn how to design resilient backup strategies that protect against data loss, ransomware, and disastersābefore you need them.
Anti-patterns are common solutions that seem reasonable but create more problems than they solve. Learn to recognize and avoid these traps before they sabotage your codebase.
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.
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.
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.
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.
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.
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.
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.
Defanging URLs prevents accidental clicks on malicious links when sharing threat intelligence. Learn why security teams use this practice and how to implement it.
Mobile devices store sensitive data and connect to critical services. Learn essential security architecture principles to protect your users from data breaches, reverse engineering, and runtime attacks.
OAuth 2.0 isn't just about getting access tokens. Learn how to design secure authorization flows that protect user data and prevent common vulnerabilitiesābefore attackers exploit them.
Logs are your application's black box recorder. Learn how to design logging strategies that turn debugging nightmares into five-minute fixesābefore you write a single line of code.
You can't fix what you can't see. Discover how proper monitoring transforms reactive firefighting into proactive problem-solvingāand why observability is your system's health insurance.
A comprehensive quick reference guide to cloud architecture patterns. Find the right pattern for your challenge with decision trees, comparison tables, and practical selection criteria.
