    Agile is Out, Architecture is Back!

    As AI-generated code transforms development workflows, the industry faces a new challenge: maintaining cohesive long-term structure. While Agile methodologies improved speed and flexibility, the focus is shifting back to architectural frameworks and processes that guide both developers and AI assistants to prevent technical debt and ensure maintainability over time.

    Delete Your Code!

    Deleting code is a critical developer skill that serves two purposes: understanding complex systems and improving code quality. When inheriting legacy codebases, strategic deletion reveals dependencies and clarifies architecture. The practice involves removing dead code, duplicate logic, and unused features while using techniques like Git bisect and feature flags. Effective deletion requires discipline through small reversible changes, test coverage, and peer review. Developer value comes from managing complexity, not maximizing lines of code written.

    The cost of design iteration in software engineering

    Software changes carry significant costs despite the lack of physical constraints. Modifying established codebases requires careful consideration of database migrations, backward compatibility, user workflows, and system integrations. Even simple changes like adding a field can cascade into major engineering efforts involving UI updates, data migration, and workflow adjustments. Large, mature systems with millions of lines of code face constraints similar to physical engineering, where iterations become increasingly expensive as systems mature beyond the initial draft stage.

    Chesterton's true lesson

    Chesterton's fence teaches engineers to understand code before deleting it, but the deeper lesson is often missed: once you understand why code exists, delete it if the purpose is obsolete. Engineering is about simplification, and in growing companies, brilliant code from months ago can become completely unnecessary as needs evolve. The key is understanding the 'why' before making decisions about legacy code.

    Kodus: Open-source AI Code Review that won’t let you break prod

    Kodus is an open-source AI code review agent that integrates with GitHub, GitLab, Bitbucket, and Azure DevOps. It allows teams to use any LLM model (OpenAI, Claude, Gemini, Anthropic), learns from existing codebases and workflows, supports custom review rules in natural language, connects with project management tools like Jira and Notion for business context, and automatically tracks technical debt by converting suggestions into issues.
