Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Raspberry Pi, InfluxDB, Grafana, Docker
It was a bit tricky to get CPU temperature of a host machine (Raspberry Pi) from within the running docker container. This Issue on GitHub has helped me :
- Arduino/ESP32 project --> Raspberry Pi 4 programming/conversion/capability?
-
What can we do with python, exactly?
No. The pi 4 is not a microcontroller. However, I would recommend gpiozero for a regular pi4

mqtt-gpio: A service which connects MQTT topics to Raspberry Pi GPIO pins
I run it in K3s on Raspberry Pi OS. The service is built on gpiozero so should work on other devices. It is a very helpful building block in my DIY home automation system. It's a general purpose connector so it can be configured for many different uses. At present I use it to:

GPIO Programming on the Raspberry Pi: Python Libraries
Gpiozero is already installed in the current Raspberry Pi OS - if not, just run python3 -m pip gpiozero. The source code files can be accessed on Github. The official documentation on readthedocs.io provides rich information and plenty example code.

Build your SO their own "attention button" this Valentine's Day
The code we will write will be in Python. Let's start with just getting the button to register. We will be using the gpiozero library to do this:

Advanced RAG with guided generation
First, note the method prefix_allowed_tokens_fn. This method applies a Pydantic model to constrain/guide how the LLM generates tokens. Next, see how that constrain can be applied to txtai's LLM pipeline.

utype VS pydantic - a user suggested alternative
2 projects | 15 Feb 2024
utype is a concise alternative of pydantic with simplified parameters and usages, supporting both sync/async functions and generators parsing, and capable of using native logic operators to define logical types like AND/OR/NOT, also provides custom type parsing by register mechanism that supports libraries like pydantic, attrs and dataclasses
- Pydantic v2 ruined the elegance of Pydantic v1
-
Ask HN: Pydantic has too much deprecation. Why is it popular?
I like some of the changes from v1 to v2. But then you have something like this [0] removed from the library without proper documentation or replacement, resulting in ugly workarounds in the link that wont' work properly.

🍹GinAI - Cocktails mixed with generative AI
The easiest implementation I found was to use a PyDantic class for my target schema — and use that as a parameter for the method call to “ChatCompletion.create()”. Here’s a fragment of the GinAI Python classes used.

FastStream: Python's framework for Efficient Message Queue Handling
Also, FastStream uses Pydantic to parse input JSON-encoded data into Python objects, making it easy to work with structured data in your applications, so you can serialize your input messages just using type annotations.

Cannot get Langchain to work
Not sure if it is exactly related, but there is an open issue on Github for that exact message.

FastAPI 0.100.0:Release Notes
Well the performance increase is so huge because pydantic1 is really really slow. And for using rust, I'd have expected more tbh…
I've been benchmarking pydantic v2 against typedload (which I write) and despite the rust, it still manages to be slower than pure python in some benchmarks.
The ones on the website are still about comparing to v1 because v2 was not out yet at the time of the last release.
pydantic's author will refuse to benchmark any library that is faster (https://github.com/pydantic/pydantic/pull/3264 https://github.com/pydantic/pydantic/pull/1525 https://github.com/pydantic/pydantic/pull/1810) and keep boasting about amazing performances.
On pypy, v2 beta was really really really slow.
