Laws of Software Engineering

📝 Discussion Summary (Click to expand)

Key Themes from the discussion

  1. “Laws” are really heuristics – Participants stress that most so‑called software “laws” are context‑dependent maxims, not immutable truths.

    “First, few of the laws on that site are actual laws in the physics or mathematics sense. They are more guiding principles.” – tmoertel

  2. Encapsulation eliminates effective complexity – Good modular design hides complexity, making it disappear for users of a component.

    “Encapsulating complexity (e.g., in stable libraries that you never have to revisit) is equivalent to eliminating that complexity.” – tmoertel

  3. Optimization is a double‑edged sword – Many warn that both premature and late optimization can be harmful; the “critical 3 %” advice is often ignored or misapplied.

    “Today, late optimization is just as bad as premature optimization, if not more so.” – tananaev

  4. SOLID and similar rule‑sets are often over‑applied – Critics argue they can foster premature abstraction and unnecessary indirection.

    “SOLID tend to encourage premature abstraction, which is a root of evil that is more relevant today than optimization.” – GuB‑42

LawMap: Interactive Knowledge Graph of Software Engineering Laws

Summary

  • A searchable, community‑curated encyclopedia of software engineering “laws”, principles, and heuristics with rich metadata and conflict tags.
  • Solves the pain point of scattered, contradictory references by letting users explore connections, contributions, and real‑world examples.

Details

Key Value
Target Audience Software engineers, team leads, educators, and students seeking a quick reference and discussion hub.
Core Feature Interactive graph view linking related laws, filtering by domain (e.g., performance, design), and community commentary.
Tech Stack Frontend: React + D3.js; Backend: Node.js + PostgreSQL; Graph engine: Neo4j; Hosting: Vercel/Cloudflare Pages.
Difficulty Medium
Monetization Revenue-ready: freemium with paid enterprise API access.

Notes

  • HN users repeatedly ask for a “canonical list” – this provides it and invites community enrichment.
  • Potential for lively discussion around contradictory laws and real‑world case studies.

CodeLaws: VS Code Extension for Real‑Time Law Violation Detection

Summary

  • Detects when code patterns conflict with known software engineering laws (e.g., DRY, PrematureOptimization, SOLID) while you code.
  • Highlights risks and suggests refactor actions directly in the editor.

Details

Key Value
Target Audience Individual developers and engineering teams using VS Code for daily coding.
Core Feature Linter rules mapped to law IDs, inline warnings, quick‑fix suggestions, and exportable compliance reports.
Tech Stack Extension: TypeScript; Rule engine: JSON‑based law definitions; Backend (optional): GitHub Actions for CI integration.
Difficulty Low
Monetization Revenue-ready: paid team license ($5/user/month).

Notes

  • Mirrors the “premature optimization” debate – users want instant feedback rather than debating abstract principles.
  • Generates discussion on which laws should be enforced automatically versus manually.

LawPrompt Library: Curated Prompt Collection for AI‑Assisted Code Generation#Summary

  • A searchable library of engineered prompts that instruct LLMs (e.g., Claude, GPT) to embed best‑practice software laws into generated code.
  • Addresses the need expressed by commenters for
  • Monetization: Hobby
