Currently powers OpenAI / ChatGPT (along with Pydantic itself), at least their Python library, maybe more. jiter has three interfaces: JsonValue an enum representing JSON data Jiter an iterator over JSON data PythonParse which parses a JSON string into a Python object jiter-python - This is a standalone version of the JSON parser used in pydantic-core. The recommendation is to only use this package directly if you do not use pydantic Brian #2: A new home for python-build-standalone Charlie Marsh See also Transferring Python Build Standalone Stewardship to Astral from Gregory Szorc python-build-standalone is the project that has prebuilt binaries for different architectures. used by uv python install 3.12 and uv venv .venv --python 3.12 and uv sync This is good stability news for everyone. Interesting discussion of prebuilt Python from Charlie Michael #3: moka-py A high performance caching library for Python written in Rust moka-py is a Python binding for the highly efficient Moka caching library written in Rust. This library allows you to leverage the power of Moka's high-performance, feature-rich cache in your Python projects. Features Synchronous Cache: Supports thread-safe, in-memory caching for Python applications. TTL Support: Automatically evicts entries after a configurable time-to-live (TTL). TTI Support: Automatically evicts entries after a configurable time-to-idle (TTI). Size-based Eviction: Automatically removes items when the cache exceeds its size limit using the TinyLFU policy. Concurrency: Optimized for high-performance, concurrent access in multi-threaded environments. Brian #4: uv: An In-Depth Guide On SaaS Pegasus blog, so presumably by Cory Zue Good intro to uv Also a nice list of everyday commands Install python: uv python install 3.12 I don’t really use this anymore, as uv venv .venv --python 3.12 or uv sync install if necessary create a virtual env: uv venv .venv --python 3.12 install stuff: uv pip install django add project dependencies build pinned dependencies Also discussion about adopting the new workflow Extras Brian: PydanticAI - not sure why I didn’t see that coming In the “good to know” and “commentary on society” area: Anti-Toxicity Features on Bluesky The WIRED Guide to Protecting Yourself From Government Surveillance Michael: Go sponsor a bunch of projects on GitHub Registration is open for PyCon Joke: Inf
