Fearless Concurrency in Python: The Lungfish Project

2025-05-18

The Project Verona team is developing Lungfish, a novel ownership model for Python designed to provide safe and efficient memory and concurrency management. They initially prototyped region-based ownership concepts using a toy language, FrankenScript, and shared their findings with the Faster CPython team. Currently, they're incrementally implementing a deep immutability model, including deep immutability in CPython, managing cyclic immutable garbage, and integrating with inter-subinterpreter messaging. This will pave the way for applying the region-based ownership model to Python, ultimately aiming to simplify concurrent programming and avoid concurrency pitfalls. The project draws heavily from languages like Rust but employs dynamic checks to accommodate Python's dynamic typing.

Hidden Gems in C's stdint.h: Beyond limits.h for Integer Type Definitions

This blog post recounts the author's unexpected discovery about integer type definitions while learning C. In the early days of C, the size of integers varied greatly across different architectures, leading compiler vendors to create custom type definitions like Microware's types.h. Later, the ANSI C standard introduced stdint.h, providing standard type definitions like uint32_t and maximum value definitions like INT_MAX from limits.h. However, the author recently discovered that stdint.h also includes definitions like INT8_MAX and UINT32_MAX, which can be directly used to define the maximum and minimum values of integer types of specific sizes, making the code more portable and avoiding errors caused by platform differences.

Cookie-Based Authentication in Axum: From Extractors to Middleware

2025-06-05

This article explores two approaches to implementing cookie-based user authentication in the Rust Axum framework. Initially, the author demonstrates using a custom extractor, `CookieJwt`, to retrieve JWT tokens from requests, conditionally rendering a 'Profile' or 'Login' button based on JWT validity. However, this approach proves less clean and scalable for complex authentication scenarios. The article then refactors the solution using Axum middleware, providing a cleaner, more reusable, and flexible approach to handling authentication logic. This middleware efficiently validates JWTs, manages refresh tokens, and gracefully handles various request types, ultimately resulting in a more robust and adaptable user authentication system. The author details the middleware's implementation, highlighting its advantages over the extractor-based approach.

Observability 2.0: Beyond the Three Pillars, Embracing Wide Events

Charity Majors of Honeycomb introduced the concept of 'Observability 2.0,' representing an evolution from the traditional 'metrics, logs, and traces' paradigm. Observability 2.0 centers around 'wide events' as a single source of truth – high-cardinality, high-dimensional event data rich in context. This allows for the retroactive derivation of metrics, logs, and traces, addressing issues like data silos and limitations of pre-aggregation. However, this transition presents challenges in event generation, data transport, storage, and querying. GreptimeDB, an open-source analytical observability database, aims to overcome these hurdles. It supports OpenTelemetry, features a built-in transformation engine, high-throughput real-time ingestion, real-time query APIs, and materialized views, providing a robust infrastructure for Observability 2.0.

The Pig: From Feast to Forbidden—A History of the Ancient Near East

This article explores the long history of pigs in the ancient Near East, tracing their journey from domesticated livestock to a religiously forbidden food. Archaeological evidence reveals pigs were a crucial food source in the early Bronze Age, but their numbers dwindled in the later Bronze Age, not due to religious taboos, but a complex interplay of factors including climate change, deforestation, and the rise of pastoralism. The Hebrew Bible's prohibition against pork likely stems from the early Israelites' nomadic lifestyle rather than health or climatic concerns. Later Greek and Roman rule saw a resurgence in pork consumption, only to decline again with the advent of Islam, though it never entirely disappeared. The story reveals how dietary habits shaped cultural identities, and how religion and politics influenced food choices.
