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.

If the native speed DOM/Web API for Rust becomes a reality, would you be willing to build your web apps with Rust and HTML/CSS?
Another strange issue could be seen in the strict class heritage organized definition of the DOM, which can not be handled very well by rust because of a still unsolved bindgen issue (#210).

Rust + WASM + Typescript [+ React]
For a much simpler but less flexible approach there's wasm-pack for creating JS packages from Rust, and wasm-bindgen for easy interop. Both have very good documentation.

We Just Released our Rust WebTransport Teleconferencing System - Here are Some Lessons Learned
We encountered quite a few hurdles on our journey. For one, we had to build our own yew-webtransport and yew-websocket integration from scratch by adding WebTransport definitions to wasm-bindgen (pull request link). We also had to add WebTransport support to the h3 crate (pull request link). co-created by @ten3roberts

Looking to create a backend service for a website in Rust and I’m wondering on how to best do it
Go with your WebAssembly module idea. Since it sounds like your chess engine does not draw a UI, it shouldn't be too difficult. wasm-bindgen will be your best friend.

Ask HN: How can a BE/infra developer handle the FE side of personal projects?
I've never tried it, but apparently some bindings exist, e.g. https://github.com/rustwasm/wasm-bindgen
So you can either try manipulating the DOM w/ some bindings or draw to canvas.

I'm trying to compile my rust code to wasm but wasm_bindgen says the trait bound `(Vec<i32>, Vec<i32>): IntoWasmAbi` is not satisfied.
Google also brings up this GitHub issue.

Deno Fresh WASM: Code Modules in Rust
If you want to learn more on wasm-pack, there is a wasm-pack book as well as some fairly detailed wasm-bindgen docs. There are a few resources for learning Rust itself in the December newsletter. Finally, please get in touch if you would like to see more content on Deno and Fresh. I hope you found the content useful and am keen to hear about possible improvements.

Swift Achieved Dynamic Linking Where Rust Couldn't
Love the article.
In my mind I see the problem of dynamic linking in rust to have a bunch of overlap with the "I want this rust library to be exposed in my higher level GC'd language with minimal safety/handwritten bindings" problem.
My hunch is that the lack of expressiveness of the C ABI is holding back both. the thing I'd love to see some sort of "higher level than the C ABI" come out. And something like `wasm-bindgen`[0] to exist for more languages.
Here's a link to the rust "interopable_api" proposal! I don't understand all the implications, but it seems to be in the right direction https://github.com/rust-lang/rust/pull/105586

The Next Browser Language
Rust has https://github.com/rustwasm/wasm-bindgen and https://crates.io/crates/sledgehammer, the latter of which batches together JS calls to reduce the FFI cost. https://dioxuslabs.com/ uses these to great effect.

1Password releases Typeshare, the "ultimate tool for synchronizing your type definitions between Rust and other languages for seamless FFI"
This seems like it could be super useful for integrating with wasm-bindgen and TypeScript. Last I checked, the types generated by wasm-bindgen left a lot to be desired (no disrespect intended, wasm-bindgen is an awesome project). A few years ago, I contributed the skip_typescript attribute to wasm_bindgen that allowed you to override the type generation by hand-writing your own types (using a custom typescript section), but I wonder if this could simply generate higher quality types without the manual intervention.
