Faster than earcut: triangulating 3.7M map polygons in 489 ms
Evgen Bodunov of Globus Software explains how the GLMap engine's polygon triangulator, now open-sourced as earstrip (one C++ header plus a WebAssembly npm build), beats earcut: 14% faster in C++ and 1.4–2.1x faster in the browser, covering convex shortcuts, triangle strips and branch-free counting.

Around The World, Part 34: A pretty sky
Thomas ten Cate continues his devlog for Around The World, a sea exploration game in early development, describing small tweaks that made sea, sky and clouds come together: reworking light scattering in clouds, physically based atmospheric scattering, horizon bending, tone mapping, and an in-engine orrery of the planet and its moon used to place them correctly in the sky.

SDF vs. MSDF vs. Slug: GPU Text Rendering
Chris Hanson compares SDF, MSDF, Slug, texture atlases, and Rive for GPU text: how signed-distance fields trade sharpness, memory, and shader cost when you draw outlines yourself.

Building a Linux GPU Driver for the M4 Mac Mini in One Month
Cody Ho and a collaborator reverse-engineered Apple's M4 AGX GPU firmware ABI and built a fully OpenGL ES 3.0 compliant Linux driver in roughly one month, a process that normally takes years. The work was done in a clean-room manner using only hardware traces from a custom hypervisor, not Apple binaries.

Why I rewrote Polygon from scratch
The creator of Polygonjs explains why, after eight years building the procedural 3D tool on TypeScript and three.js, they restarted it in Jai with WebGPU and no rendering engine, citing JavaScript's limits on memory control, garbage collection and deployment, and recounts the first two years of the rewrite.

One of the unwritten rules of the Internet seems to be that whenever something Amiga-related is mentioned, at least one Amiga fan myself included must show up and try to explain the concept of screens. Amiga screens can have different resolutions, we'll tell you, and one can drag them, we'll say, and other Amiga users rally in agreement, while non-Amiga users probably still don't get what's so great about screens. Until now, when this text has been written, in the hope of converting unsuspecting normies into full-blown Amiga screen lovers.
