Specific language that I want to learn: - Java - Typescript - Golang - Rust
Even though I don't use C++ at all, he explains concepts so well that I've been able to learn a lot.
He also has some videos using Rust to build the SerenityOS Programming Language, Jakt [1]. The compiler eventually became self-hosted, so more recent videos don't contain Rust code, but earlier ones are a goldmine.

You can usually find VODs of his livecoding sessions on youtube as well. Well worth watching.
