Michael #1: jiter

Fast iterable JSON parser.
About to be the backend for Pydantic and Logfire.
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
