The reason is that you think you understand what you read, but as Richard Feynman said:

You think you understand 90% of what you read, but in reality it's probably only 20-30%. By doing the exercises, at the very least you'll know that you don't know that much. And if you then reread the materials a few pages before, you'll realize that you have skimmed (or worse, skipped) some parts because you mistakenly thought you already understood it.
Another tips from my personal experience: When you're reading a textbook, keep asking in your mind questions with the types of "what if" and "how about," which are sometimes not yet explained in the section you're reading. Also, keep associating what you've recently learned with what you've already known (days ago, years ago).
Be curious and validate that you really understand what you think you understand.
Except those people who have "mediocre soundbars" can't afford buying a $3.5K VR headset. And those who have a spare budget of $3.5K to enhance their TV watching experience will invest the money on a better TV and a surround speaker setup.

TIL that HN doesn't use a "proper" / persistent DB. I wonder then how HN handles data persistence. Is it as simple as creating write-ahead logs + checkpointing every some duration?
