Mypy 1.6 Released
Pyright doesn't work with Django, as Django's so dynamic that it requires a plugin to infer all types correctly. Sadly, even mypy with plugins is a mess to get set up in vscode, especially if you want it to use the same config as you use for ci checks from the command line.
We use mypy + [django-stubs](https://github.com/typeddjango/django-stubs) (in a huge Django + drf project at day job) which includes a plugin for mypy allowing it to recognize all reverse relations and manager methods. Mypy is still really rough around the edges. The cli args are poorly documented, and how they correspond to declarations in a mypy.ini / pyproject.toml is mysterious. Match-statements still have bugs even a year after release. Exclusion of untyped / partially typed files and packages we've had to solve with grep filtering mypy's output for our whitelisted set of files, as it's been unable to separate properly between errors you care about (in your own codebase) and errors in others code (dependencies, untypable dynamic python packages etc).
The largest issue IMO is that mypy tried to adapt a java / OOP style way of type system onto python, instead of recognizing the language's real power within duck typing and passing structural types around. Typescript chose the right approach here, modelling javascript the way it is actually written, favoring structural over nominal typing, instead of the archaic and now left-behind way of Java-style OOP that has influenced mypy.
There was a recently accepted PEP which allowed for limited dataclass transforms, enough to cover the @attr.s usecase for both mypy and pyright, but nowhere near expressive enough to cover django's models and ORM sadly. It's probably impossible / undesirable to allow for such rich plugins, so i see the future for proper pluginless typing to be more akin to how pydantic / normal dataclasses solve typing, by starting with a specification of the types, deriving its runtime implementation, instead of plugins having to reverse the type representation of a custom DSL.

Boring Python: Code Quality
You can annotate the manager and get some typing help in the editor. And there’s django-stubs which helps a little when running mypy. It’s not as good as pycharm though.

Python 3.11.0 final is now available
> Yes, there are type stubs for these libraries but they’re either forced to be more strict, preventing use of dynamism, or opt for being less strict but allowing you to use all the library features, at the cost of safety.
There are type stubs for Django that somewhat avoid these compromises: https://github.com/typeddjango/django-stubs
To be able to do this they have to use a Mypy plugin though. And even then it's still far from perfect.

Rust – Faster compilation with the parallel front-end in nightly
https://github.com/grapl-security/grapl/
I just did a clean build `cargo build`, 19 minutes 44 seconds.
I added 1 line (`dbg!("foo")`) and it took 14.76s

Introduction to Curp Protocol
Awesome. So, CURP was pretty inspiring for the work I did on Grapl. Grapl Schemas had to define conflict resolution algorithms.
https://github.com/grapl-security/grapl/blob/main/etc/exampl...
As you can see here, there are some special built-ins that aren't important (keys, timestamps) but you can see there's @immutable (FWW) and @increment_only.
This meant that our graphs formed a big CRDT, which meant that every operation commuted, which meant that we could do weird things with our consensus. Reads could happen on stale data, writes could be dropped, we could read from two inconsistent databases and resolve the inconsistency in memory, etc. I even hacked this into ScyllaDB by encoding each merge function into an integer, and setting that as the TIMESTAMP, for when replication merging happened to the values - this meant we could perform writes (repeatedly) without reading a value first, and with no coordination between nodes. What I didn't have was a native solution that could take advantage of these constraints.
As you can tell, this project is obviously very interesting to me. I ran through this pretty quickly but I'll dig in more soon. I'm just excited to see this.
