Hello! I'm enjoying this lecture as well as other lectures! [Numbers -> Characters -> Code Systems -> Unicode + Encoding -> ... ] Rather than simply explaining the meaning of words in this flow, you explained how it started in the past, what inconveniences there were, what came out to supplement that, and what new things came out to additionally supplement the inconveniences felt again - sharing this historical flow together makes it easier to understand. Additionally, you explained in detail even how to perform bit and radix operations, taking me beyond simple memorization to the realm of understanding... (The phrase "Think of code systems and encoding as separate things" is stuck in my head..) Thank you always for lectures that are like light and salt to me.
