Joined January 2013
Started actively working on the next challenge today: "Build your own SQLite". I've got the stages planned out, now onto building the test cases and trying the challenge out myself. Will post updates here as I go.

Announcing our next challenge: "Build your own SQLite". In this challenge, you'll build a barebones SQLite implementation that supports basic SQL commands like SELECT/INSERT. Along the way we'll learn about SQLite's file format, your indexed data is stored in B-trees and more.

Ask gpt-4o to generate an image with a clock and it ALWAYS uses 10:10 as the time, even if you ask for a different time in your prompt. Ask it again to change the time and it goes bonkers:
