Finite time blowup for an averaged three-dimensional Navier-Stokes equation

https://terrytao.wordpress.com/wp-content/uploads/2014/02/circuit-1.png?w=490
I’ve just uploaded to the arXiv the paper “Finite time blowup for an averaged three-dimensional Navier-Stokes equation“, submitted to J. Amer. Math. Soc.. The main purpose of this paper is to formalise the “supercriticality barrier” for the global regularity problem for the Navier-Stokes equation, which roughly speaking asserts that it is not possible to establish global regularity by any ...

Visualizing Rust's Vtables: How dyn Trait Works In Memory

https://sofiabelen.github.io/projects/visualizing-rusts-vtables-how-dyn-trait-works-in-memory/Rust_fungus_-_Flickr_-_gailhampshire_hu_f9f62a9c4cc3178c.jpg
The author is comparing Rust's approach to polymorphism with C++'s, highlighting the differences between static and dynamic dispatch. They explore how Rust uses monomorphization for compile-time polymorphism and dyn Trait for runtime polymorphism, which differs from C++'s vtable-based approach.
