FastAPI-Crons is a Python library that enables cron job scheduling directly within FastAPI applications using decorators, eliminating the need for separate worker processes. It supports async/sync functions, retries, timeouts, distributed locking, and persistent state management via multiple backends.
Russell shares principles for optimizing Tokio async applications based on discussions at RustConf, emphasizing the balance between fairness and batching. Key insights include determining if a performance problem actually exists before optimizing, using scheduling latency metrics for diagnosis, and yielding frequently to reduce latency while batching to improve throughput. The post notes that most performance issues stem from application code rather than Tokio itself.
Effect-TS is a TypeScript library designed for building reliable systems with typed error handling, automatic retry logic, and structured concurrency. It provides comprehensive error tracking, validation, and observability features suitable for production applications and AI agent development.
Russell shares principles for optimizing Tokio async applications based on discussions at RustConf, emphasizing the balance between fairness and batching, and explaining how to diagnose real performance problems using metrics like scheduling latency rather than assuming issues exist.
A C# developer's progress callback wasn't being invoked during an async download operation. The root cause was that the C++/WinRT DownloadAsync method wasn't forwarding progress reports from the underlying provider operation, only awaiting and returning its result. The fix is to return the provider's IAsyncOperationWithProgress directly instead of wrapping it in a coroutine that doesn't relay progress.
Rustls, a Rust-based TLS library, celebrates its tenth anniversary with significant growth from its first commit in May 2016 to version 0.24. The project evolved from early community contributions to funded development through CNCF and ISRG's Prossimo initiative, delivering major features like FIPS certification, post-quantum cryptography, and improved async support.
