Project mention: Web scraping of a dynamic website using Python with HTTP Client | dev.to | 2024-09-28
The library already has support for an HTTP client that allows bypassing Cloudflare - CurlImpersonateHttpClient. Since we have to work with JSON responses we could use parsel_crawler added in version 0.3.0, but I think this is excessive for such tasks, besides I like the high speed of orjson.. Therefore, we'll need to implement our crawler rather than using one of the ready-made ones.

datasketch
MinHash, LSH, LSH Forest, Weighted MinHash, HyperLogLog, HyperLogLog++, LSH Ensemble and HNSW

msgspec
A fast serialization and validation library, with builtin support for JSON, MessagePack, YAML, and TOML
gjson [1] and a few other go packages offer a way to parse arbitrary JSON without requiring structs to hold them.
re: Python. I like PyRight/PyLance for Python typing, it seems to "just work" afaict. I also like msgspec for dataclass like behavior [2].

I dont think it is about discipline. At its core, a good test will take an example and do something with it to demonstrate an outcome.
That's exactly what how to docs do - probably with the same examples.
Logically, they should be the same thing.
For example:
https://github.com/crdoconnor/strictyaml/blob/master/hitch/s...
And:
https://hitchdev.com/strictyaml/using/alpha/scalar/email-and...
You just need a (non turing complete) language that is dual use - it generates docs and runs tests.

jsonpickle
Python library for serializing any arbitrary object graph into JSON. It can take almost any Python object and turn the object into JSON. Additionally, it can reconstitute the object back into Python.
Project mention: Show HN: Mutuple – Replace items in Python's "immutable" tuples | news.ycombinator.com | 2024-04-10While I mostly wrote `mutuple` for fun, it's also a proof of concept for solving a tricky pickling problem in the jsonpickle[1] library: restoring object graphs that contain tuples with back-references to the same tuple.
I'm pretty sure there are better ways of handling this edge case, but, hey, it works and was a pretty fun experiment.

mcap
MCAP is a modular, performant, and serialization-agnostic container file format, useful for pub/sub and robotics applications.
Seems like it's aiming to be a more general alternative to tools like ROS rosbags, pretty widely used in robotics. Sounds like a good idea to me -- having a nice tool to create and visualize multimodal logs can be pretty useful outside of robotics.
Foxglove (https://foxglove.dev/) is an alternative specifically aimed at robotics. It was originally a fork of Cruise webviz (https://webviz.io/), iirc, which came out of the ROS ecosystem. The format for ROS logs (rosbags) has evolved a bit - from a custom format, to a format based on sqlite, to a new format that is intended to be more general and compatible with various serialization formats, MCAP (https://mcap.dev/).
