BugBash'26 Afternoon of Day 1

Summary

The BugBash'26 afternoon sessions featured insights into software development with AI agents, high-performance distributed systems, and reliable storage. Ben Eggers from OpenAI argued that despite LLMs making code generation cheap, the fundamental hard parts of software development—design, discovery, integration, and correctness—remain. He emphasized that LLMs move work rather than eliminate it, requiring specific prompting, hand-written schemas, and separate test implementations. Matt Barrett of Adaptive discussed their Aeron cluster, a Raft implementation supporting 100K transactions/sec with low double-digit microsecond latency, noting its innovation lies in low-level data handling and networking. Corwin Coburn from Google detailed building the world's fastest Lustre filesystem at 10 TB/sec, stressing the importance of "boring" storage through reliability, strict tenancy isolation, and achievable SLOs, cautioning against over-delivering due to Hyrum's law.

Key takeaway

For AI Engineers integrating LLMs into deep narrow systems, recognize that while code generation is faster, you must still lead the design, define success, and hand-write critical interfaces and tests. Do not outsource your core thinking or understanding to agents. For distributed systems architects, prioritize reliability and achievable SLOs over perceived innovation, especially in high-performance storage.

Key insights

LLMs make code cheap, but core software design, correctness, and reliable system engineering remain human-centric challenges.

Principles

• Writing code exposes design flaws.
• LLMs shift, not eliminate, development work.
• Reliability trumps innovation in storage.

Method

Design the hardest parts, write schemas and APIs by hand, and implement tests in a different context, then ask the LLM to write the code.

In practice

• Hand-write APIs and schemas.
• Implement tests separately from LLM-generated code.
• Avoid filesystem metadata for queries.

Topics

• LLM Code Generation
• Software Engineering Principles
• Distributed Systems
• Raft Consensus
• High-Performance Storage
• System Reliability
