I've been looking for a really engaging solid intro to number theory course on youtube, including rings, Abelian groups, etc for early teens.

Does anyone have a recommendation here?

Or go for one of these gamified math tutorials.

For instance: this one teaches geometric proofs without mentioning the formalism, just letting you "unlock" the tools from a few "axiom" starter tools.

This is similar to the solution we used in Vega Strike https://www.vega-strike.org/ detailed here https://graphics.stanford.edu/~danielh//classes/VegaStrikeBl...

This article mentions the woes of circular imports. I thought MyPy let you work around that by doing if False: around your imports

eg a.py: import c

  if False:
     import b

  class X:

   def x(self):
       #type: () -> b.Y
       from b import something_that_returns_y

       return something_that_returns_y(self)

b.py:

  from a import X

  class Y:

    pass

  def something_that_returns_y(x : X) -> Y:

    return Y()

I think the newer version of this is https://github.com/bazelbuild/rules_rust which lets you either vendor the dependencies or pull them from your Cargo.toml directly every time.

Per the article: bazel + rules_rust should have the flexibility to override the linker flags that Cargo may take as required since that would be a property of the bazel toolchain used.

It's a nice amalgamation of how cargo works and how bazel works.

In general bazel supports hermetic builds, multiple toolchains, cross complilation, and ways to compile multi-language projects.

I still wish that Cargo.toml didn't support build.rs as it can cause a lot of system-dependent problems that bazel sidesteps entirely by being hermetic.
