The act() function is a crucial but often misunderstood aspect of testing React applications. It is essential to wrap any functionality that updates the internal state of a rendered component in act() to ensure that all state changes and side effects are fully processed before proceeding with assertions in your tests. This helps in making your tests realistic, preventing potential bugs by avoiding assertions on outdated state values. Using React Testing Library (RTL) functions generally abstracts away the need to manually use act(), as they automatically wrap their functionality in it

Chronon is a Rust-based implementation of a distributed state machine that ensures deterministic behavior and crash safety, with a focus on achieving exactly-once side effects. It utilizes Viewstamped Replication (VSR) and a durable outbox pattern to maintain data integrity and prevent duplicate executions of side effects, such as emails or API calls, which are challenging in distributed systems. Chronon separates control mechanisms, like heartbeats and elections, from data processes, enhancing its reliability. Currently, it is under active

The content discusses the evolving concept of source code in the context of AI-generated programming. It raises questions about whether prompts used to generate code should be considered the actual source code or if the generated code itself (like Python) is the source. This debate is highlighted by a survey where developers expressed mixed feelings regarding the visibility of prompts to code reviewers. As the industry adapts to this new paradigm—exemplified by Cursor's acquisition of Graphite and Meta's development of internal tools for publishing prompts—
