Lessons

Daily lessons — one idea at a time, explained plainly, with something small to try and a source to read further.

One concept per day. Each lesson explains the idea in plain terms, gives a small thing to try, and links its source. Grouped by week; new lessons get a page as they are shared.

Week 1

  1. W1 · Lesson 1: What a CPU actually does ·
    Fetch, decode, execute — the tiny loop a CPU runs forever, and why every if, for and function call ends up inside it.
  2. W1 · Lesson 2: Retries are selfish ·
    Backoff and jitter — why retrying politely is the difference between a blip and a storm.
