Le 12 Regole di Codd del 1985 rimangono il fondamento dei database relazionali, eppure molti sviluppatori le ignorano bellamente. Così nascon sistemi fragili e difficili da mantenere. Tornare alle basi non è nostalgia, è buonsenso.

Elixir v1.20, released, introduces a set-theoretic gradual type system enabling optional type annotations without altering old codebases, with direct compiler integration.

The hype around LLM agents transforming backend development is mostly hot air for production systems. A recent arXiv paper reveals 'constraint decay,' where agents lose an average of 30 points in assertion pass rates when moving from loose baselines to fully specified backend tasks. This isn't a minor bug; it's a fundamental limitation.

Large Language Model (LLM) agents demonstrate strong performance in autonomous code generation under loose specifications. However, production-grade software requires strict adherence to structural constraints, such as architectural patterns, databases, and object-relational mappings. Existing benchmarks often overlook these non-functional requirements, rewarding functionally correct but structurally arbitrary solutions. We present a systematic study evaluating how well agents handle structural constraints in multi-file backend generation. By fixing a unified API contract across 80 greenfield generation tasks and 20 feature-implementation tasks spanning eight web frameworks, we isolate the effect of structural complexity using a dual evaluation with end-to-end behavioral tests and static verifiers. Our findings reveal a phenomenon of constraint decay: as structural requirements accumulate, agent performance exhibits a substantial decline. Capable configurations lose 30 points on average in assertion pass rates from baseline to fully specified tasks, while some weaker configurations approach zero. Framework sensitivity analysis exposes significant performance disparities: agents succeed in minimal, explicit frameworks (e.g., Flask) but perform substantially worse on average in convention-heavy environments (e.g., FastAPI, Django). Finally, error analysis identifies data-layer defects (e.g., incorrect query composition and ORM runtime violations) as the leading root causes. This work highlights that jointly satisfying functional and structural requirements remains a key open challenge for coding agents.

Most devs think backend = APIs.
It’s not.
It’s:
• Efficient request handling
• Clean architecture
• Smart DB design
• Caching strategies
• Security
• Reliability under load
Great backend ≠ just code
It’s systems that don’t break in the real world.
Tools change. Principles don’t.

Most devs jump into microservices too early
Truth: most systems don’t need it at the start.
It adds complexity—network calls, harder debugging, data issues.
Start with a monolith. Scale when needed.
Right architecture > complex architecture.
