How Do Computers Remember?

Displaying numbers is trickier than I expected! In this video we explore how to visualize the data inside of our simulated 4-bit registers, with the help of the double dabble algorithm and some seven segment displays.

The latest version of the simulation software is now available here: https://sebastian.itch.io/digital-logic-sim
And the source code is here: https://github.com/SebLague/Digital-Logic-Sim

Polishing and Releasing My Tiny Geography Game

Welcome to the first part in a series teaching pathfinding for video games. In this episode we take a look at the A* algorithm and how it works.

Some great A* learning resources:

Trying to Improve My Geography Game with More Real-World Data

I've recently been on a streak of unfinished projects, so I decided to focus one week on actually completing something -- anything! I thought it would be fun to make a small game, and so I asked an AI for some ideas...

I Spent a Week Making an AI's Video Game Idea

In this coding adventure I attempt to simulate a simple ecosystem. Will the foxes and rabbits get along? Probably not...

This video was inspired by Primer's series on evolution. I highly recommend taking a look!
https://youtu.be/0ZGbIKd0XrM
As many in the comments have said, if you enjoy this, you may want to check out equilinox, which is an entire game based around creating an ecosystem. It’s awesome. https://youtu.be/lHHpMn2UK6s

Source code:
The source for this video is a total mess, which I don't really want to share!
I'm working on a second part though, and you can find the work-in-progress code for that here: https://github.com/SebLague/Ecosystem-2/tree/master
