Learn JS Series (#26) - Currying and Partial Application What will I learn You will learn what currying is: turning a multi-argument function into a chain of single-argument functions; the difference between

Every day, millions of people use smartphones, laptops, and online services without realizing how many cyber threats exist. Cybersecurity is no longer only for hackers or IT experts; it has become an essential

Learn Zig Series (#162) - Sprite Rendering and Tile Maps What will I learn? What a sprite actually is -- a small pre-drawn image you stamp onto the screen wholesale, in stead of rebuilding it from lines

Learn Rust Series (#50) - anyhow: Flexible Application-Level Errors & Context What will I learn You will learn how the anyhow crate handles errors in application code with almost no ceremony; how

Learn JS Series (#25) - IIFEs and the Module Pattern (the Pre-2015 Way to Get Privacy) What will I learn You will learn what an IIFE is, and the syntax trick that makes it work; why IIFEs were essential

Learn Zig Series (#161) - Double Buffering and Vsync What will I learn? Why drawing straight into the memory the display reads from makes shapes flicker and tear, and why "just draw faster" does

Learn Rust Series (#49) - thiserror: Ergonomic Library Errors What will I learn You will learn how the thiserror crate generates error boilerplate from a few attributes; how #[derive(Error)] and

Learn JS Series (#24) - Recursion: Base Cases, the Call Stack, and Stack Overflows What will I learn You will learn what recursion is, and the two ingredients every recursive function needs; how the call

Learn Zig Series (#160) - 2D Transform Matrices What will I learn? Why every shape we have drawn so far is nailed to fixed pixel coordinates, and why hand-editing vertices to move it is the wrong answer;

Have you ever thought about creating your own app—incorporating exactly the features you want—or turning an idea in your mind into a fully functional website, all without opening a code editor or installing

Learn Rust Series (#48) - Custom Error Types & the std::error::Error Trait What will I learn You will learn how to design a custom error type as an enum of failure cases; how to implement Display for

Learn JS Series (#23) - call, apply, and bind: Controlling this Explicitly What will I learn You will learn exactly what call, apply, and bind do, and how they differ; how to borrow a method from one object

Learn Zig Series (#159) - Polygon Filling: Scanline What will I learn? Why an arbitrary polygon cannot lean on the tidy symmetry that made circles and ellipses easy to fill; The even-odd (parity) rule:

Learn Rust Series (#47) - Option Combinators & Null-Free Programming What will I learn You will learn how to transform and chain Option values without writing a single match; how map, and_then, and

Learn JS Series (#22) - The this Keyword: Five Rules That Explain Every Case What will I learn You will learn that this is decided by HOW a function is called, not where it is defined; the five binding

Learn Zig Series (#158) - Circle and Ellipse Rasterization What will I learn? Why a circle fights the pixel grid even harder than a line does, and why the obvious y = sqrt(r*r - x*x) approach leaves ugly

Learn Rust Series (#46) - Result Combinators: map, map_err, and_then, ok_or What will I learn You will learn how to transform a Result without writing a match at every step; how map and map_err change
