Making Minecraft Spherical

news.ycombinator.com Unknown 2025-10-13 14:12:34

Blocky Planet is a tech demo I created in the Unity game engine that attempts to map Minecraft’s cubic voxels onto a spherical planet. The planet is procedurally generated and fully destructible, allowing players to place or remove more than 20 different block types. While much of the implementation relies on common techniques you’d expect from your average Kirkland brand Minecraft clone, the spherical structure introduces a number of unique design considerations. This post will focus on these

Multi-Timer Gizmo

Menu Multi-Timer Gizmo My friend, Dave Gauer, built a “multitimer” back in 2021. It is a small desktop gizmo for keeping track of time spent on rapidly switching tasks. One pushes a button and time starts accumulating on that button’s timer. Dave’s multi-timer is based on a RaspberryPi Pico — fancy micro-computer stuff. In fact, his unit has three distinct microcontrollers in it: the keypad and LCD each have their own! Did an academic already do this? Thinking about Dave’s multi-timer, I was

Level has always impressed me with its smart locks that look just like normal home deadbolts, but house compact tech features include card-tapping access, app controls and Apple Home Key support. Its newest Level Lock Pro, available now at Level's own websites, follows the same design and adds even more features, including more complete Matter support.

The Block Stacking Problem

news.ycombinator.com Unknown 2025-11-02 14:01:44

The Block Stacking Problem John D. Norton Department of History and Philosophy of Science University of Pittsburgh https://sites.pitt.edu/~jdnorton/jdnorton.html February 21, 2025 1. Introduction In the block stacking problem, a collection of blocks are to be stacked at a table edge. If we stack the blocks so that they protrude past the edge of the table, how far can they go horizontally? The curious and then surprizing result is that we can extend the stack horizontally arbitrarily far.

Before I start - Yes, I know the differential equation in the video is wrong. I’ve already fixed it by tweaking the prompt and the script so the inputs depend on what’s being asked. The original issue was that blocks like Sum were being pasted in without matching the right number of inputs and outputs. I’m a 2nd-year aero-engineering student at Imperial College London, I enjoy problem solving (did BPhO - gold and UKMT Gold) I'm a full-stack dev (or atleast trying to be lol) who hacked together
