The author built a custom budget Laser Fault Injection Platform to defeat the RP2350 Hacking Challenge, demonstrating that a single laser-induced fault can bypass the RP2350's Secure Boot and recover OTP secrets despite hardware hardening like the Redundancy Co-Processor and glitch detectors.
作者分享了一次因重试导致重复扣费的线上事故，并介绍其正在构建的 FetchSandbox 工具——通过确定性故障注入检查工作流重试时的幂等性是否真正生效。
The celld team describes how they use deterministic simulation testing (DST) to explore event orderings and reproduce hard-to-reproduce bugs in their Cloudflare Workers/Durable Objects runtime, including how a seeded simulator controls scheduling, storage faults, and time to verify system invariants.
This paper investigates where exactly-once behavior should be enforced in LLM agents to prevent duplicate side effects, using a deterministic sandbox named Limbo to test across models, harnesses, and tool contracts under various fault conditions.
This paper introduces a deterministic testbed for evaluating LLM judges on agent trajectories, showing that outcome-only judges miss silent faults while step-based judges achieve higher recall with better calibration.
This paper introduces GPU undervolting as a hardware-level defense to improve CNN adversarial robustness and energy efficiency during training by inducing beneficial stochastic faults.
This paper introduces TS-Fault, a benchmark for evaluating time series forecasting models under structured fault scenarios like broken dependencies and regime changes, finding that clean-data accuracy often anti-correlates with robustness and that foundation models are especially fragile.
A deep dive on Antithesis, a multiverse debugger for large distributed systems that offers deterministic replay and fault injection, now available as a free article.
Two skills for AI coding agents that design and run claim-driven tests for distributed and stateful systems, producing structured test plans and findings reports with 9-state verdicts and blame classification.
