A new technical article explains the dual polytope and how it can be used for hull simplification in computational geometry. The piece walks through the underlying mathematics and its practical applications, and is drawing attention from developers and programmers interested in geometry, graphics, and algorithmic techniques.

Hackers on Hackaday have documented how to take control of the on-screen display (OSD) chip found in cheap composite monitors, showing how the character generator and menu overlay hardware can be driven directly. The write-up walks through identifying the chip, its communication lines, and injecting custom text or graphics onto the screen. Readers are discussing the possibilities for retro computing projects, custom overlays, and reused surplus displays.

A new video essay asks what computing would look like if the industry moved away from GPUs, questioning how dependent AI and graphics workloads have become on a small number of chip suppliers. The piece is drawing attention on Hacker News, where readers are debating the economics of GPU dependence, alternatives like CPUs, ASICs and emerging accelerators, and what a shift could mean for companies such as Nvidia.
