Algorithms Without Code: Small Methods for Six Everyday Lives | Private AI Cluster Log, Day 10

Yesterday's twenty algorithms were on the technical side. Today they turn into the everyday lives of six people: two university students, three office workers and a part-timer. Each person gets three common problems, each with a small method you can simply follow, a real-life example and one sentence you can paste into an AI chat. It ends with a mini encyclopedia of 53 methods to check when you get stuck.

Bringing Algorithms and AI into Everyday Life: Twenty Algorithms and a Strategy Router That Grows | Private AI Cluster Log, Day 9

Grinding problems is not about memorizing answers. It is about recognizing a problem's shape at a glance. This post sorts twenty common algorithms into five groups, reading data, making choices, ordering work, breaking things down and running for the long term, each illustrated with a fictional character, Ming, plus a diagram, steps, an AI prompt template and common misuses. It ends by combining all twenty into a strategy router: give it a goal, and it picks the algorithms to use, puts them in order, and gets better after every review.
