Summary

BugBash'26 Morning of Day 1 featured several talks on distributed systems, infrastructure, and software quality. Peter Alvaro, Associate Professor at UC Santa Cruz, reflected on 20 years of distributed systems research, detailing approaches like arcane algebras, lineage-driven fault injection, and simulation for metastability, acknowledging their limitations while emphasizing ongoing progress with new methods like Descartes for deterministic testing. Deb Chachra, Professor of Engineering at Olin College, presented a broader perspective on infrastructure, defining it as relational and having a trajectory, and discussing its political implications, particularly regarding decentralized renewable energy. Lightning talks covered kernel bug patterns, noting 30% hide over 5 years, and the potential for LLMs to exacerbate concurrency issues. Fernanda Graciolli discussed formal verification in web development, leveraging AI for Dafny proofs and a Dafny to React workflow. Oskar Wickström introduced Bombadil, a property-based testing tool for web applications in TypeScript/JavaScript.

Key takeaway

For software engineers and research scientists tackling distributed systems, recognize that no single "silver bullet" solution exists for robustness. Instead, continuously evaluate and combine diverse approaches like deterministic testing and fault injection, while acknowledging their specific limitations. For AI engineers, consider integrating formal verification early in your web development workflow, as AI tools now facilitate proving pure logic in specs before code compilation, which is increasingly critical given AI's potential to introduce new bug patterns.

Key insights

Peter Alvaro's 20-year journey in distributed systems reveals no silver bullet, but continuous progress through diverse, evolving approaches.

Principles

Method

Formal verification involves proving pure logic in specifications (e.g., Dafny) before compiling to components, iterating on specs, not code.
