Split Agent Architecture in Harness: Separating Reasoning from Execution

Harness separates its AI coding agent into a lightweight planner and a sandboxed executor. Here’s why that split matters for latency, security, and observability.

Why Hardware Transactional Memory Failed to Go Mainstream

Hardware transactional memory promised easy lock‑free programming, but a mix of hardware complexity, unpredictable performance, high silicon cost, and insufficient language and library support kept it from widespread adoption.

Formal Verification of Lockless Data Structures Using TLA⁺

This article walks through modeling lock‑free queues and stacks in TLA⁺, proving safety and liveness, and offers practical tips for scaling verification to production code.

How Formal Verification Prevents Deadlocks in Concurrent Rust Systems

A deep dive into how formal verification methods—like model checking and type‑level proofs—eliminate deadlocks in Rust’s concurrent code, with practical examples and tool recommendations.
