This Week I Learned #8

Here are some of the things I learned this week, in the order I’ve noted them down.

  • The difference between input and output randomness in game design (video). The gist of it that randomness that occurs before a player action is referred to as input randomness—a prominent example being procedural level generation—while randomness that occurs after user action is called output randomness, such as the case with loot boxes and success rates.

# Programming

  • I’ve been using Markdown for years, but I never realized you could add image titles like this: ![Alt](/url/to/image.jpg "A title"). Granted, I usually avoid using the title attribute for the reasons outlined here.

  • Core Data became a lot easier to work with since the last time I used it, which was before NSPersistentContainer for those familiar with the framework.1

  1. It still feels clunky by today standards—can we have the Codable of data persistence already?
