New Typing Features in Python 3.13: ReadOnly, @warnings.deprecated, TypeIs, is_protocol, get_protocol_members, Default TypeVars, NoDefault, and Performance Improvements

Python 3.13 introduces a suite of typing enhancements—including a ReadOnly type for TypedDict, a @warnings.deprecated decorator, the TypeIs construct, is_protocol and get_protocol_members utilities, default TypeVar support with has_default(), the NoDefault sentinel, and several performance and API clean‑ups—providing developers with more expressive and efficient static type checking capabilities.

Why Thread.stop and Thread.suspend Are Deprecated and How to Gracefully Stop Threads in Java

This article explains why the Thread.stop and Thread.suspend methods were deprecated in modern Java, demonstrates the problems they cause with concrete code examples, and presents two safe alternatives—using a shared flag and the interrupt mechanism—to gracefully terminate threads without risking deadlocks or resource leaks.
