Hello World Under The Microscope
tl;dr: "We will trace the execution path of the "Hello World" micro-program written in Python and run on Windows, starting from a single call to the high-level print function, through the subsequent levels of abstraction of the interpreter, operating system and graphics drivers, and ending with the display of the corresponding pixels on the screen. As it turns out, this path in itself is neither simple nor short, but definitely fascinating."featured in #359

How To Solve The Sudoku Puzzle With Programming
- Hillel Wayne tl;dr: "Sudoku is an example of a constraint problem. Most “solving sudoku” tutorials use either backtracking or constraint propagation. These same techniques apply to all constraint problems, and since such problems are so widespread, it doesn’t make sense to custom build an algorithm for every single one. Rather, we want general-purpose constraint solvers we can apply to arbitrary problems."featured in #354
