array programming

David Sanders gives the first part of a two-part introduction to the Julia programming language at SciPy 2014. It walks through the language's basics and its appeal for scientific computing.

David Beazley's PyCon 2019 tutorial derives the lambda calculus from the ground up in Python, using only single-argument functions. He builds booleans, numerals and more with no other language features.

Day 21 of Casey Muratori's Handmade Hero, which covers loading game code dynamically from a DLL on Windows. He builds hot reloading of C game code from scratch in about an hour and a half.

David Beazley's workshop screencast builds asynchronous programming in Python from scratch, starting from callbacks and continuations and replacing threads to show how concurrency works underneath.

A long Tsoding Daily programming stream in which he implements hot code reloading in C by loading a dynamic library at runtime without stopping the main program. It also touches on migrating struct versions across reloads.
