A video clip of computing pioneer Alan Kay is circulating on Hacker News, in which he discusses Claude Shannon, the mathematician who founded information theory. The snippet shown references Shannon's work on handling noisy communication channels, a foundational idea behind modern digital communication and computing. Commenters appear drawn to Kay's reflections on computing history and theory, though the full context of the discussion is limited to a single post with around 140 points and no visible thread detail.

A new technical write-up explains the dual polytope concept and how it can be applied to simplify convex hulls in computational geometry. The piece walks through the underlying mathematics and demonstrates practical uses for reducing hull complexity. Readers with interests in geometry, graphics, and algorithms are engaging with the detailed explanation.

In 1820, mathematician Carl Friedrich Gauss reportedly proposed carving gigantic right-angled triangles or squares into Siberian forests by clearing trees, planting wheat in between, hoping the geometric shapes would be visible from space and signal intelligent life. The anecdote is circulating again on social media, drawing amused and fascinated reactions as an early example of communication with extraterrestrial intelligence, long before modern SETI efforts.

Shor's algorithm, developed in 1994 by American mathematician Peter Shor, is a quantum algorithm for finding the prime factors of an integer. Its theoretical power threatens widely used encryption, and that is credited with prompting a global shift toward post-quantum cryptography, as researchers and governments prepare security systems resistant to future quantum computers.
