Overview

Absolutely — great job finishing Problem Solving (2nd Edition) by S. Ian Robertson. It’s a dense book but one of the most practical introductions to how humans actually solve problems, why we sometimes fail, and how to deliberately improve.

Below is a structured refresher plus concrete, actionable takeaways tuned for your personal learning style (you tend to like systems, breakdowns, templates, right-brain/left-brain alternation, and deep skill-building).

🧠 High-Level Summary of the Book

Robertson’s core premise:

Cannot scroll through terminal. Scroll wheel instead will scroll through command history #175586

Original post: microsoft/vscode#175586

I also ran into a similar issue where, when I scroll on my terminal window, it doesn't scroll the entire output, but scrolls through my command history, its very annoying. I found the above post #175586, it ended unsolved.

Here is my fix, and it was related to setting I had done earlier but forgotten about:

terminal.integrated.scrollback and setting it to 0, thinking that this would set my output buffer to be unlimited, but it really sets my scrollback buffer/window size to 0.
FIX: Set terminal.integrated.scrollback to some large number and re-open the terminal, instead of 0.

	"""
	Multi-player generalization of the Red & Black Knights construction.

	Same square spiral, same "smallest unoccupied cell not threatened by a
	hostile piece" rule, but the number of players, the move set of each
	player's piece, and the directed threat relation between players are all
	configurable. The two-knight case (OEIS A392177) is recovered with two
	knight players that mutually threaten each other.

	"""
	Red & Black Knights on a square spiral.

	Construction (OEIS A392177 / A392178 / A395357, Numberphile 2026-05-12):

	Number the cells of an infinite square spiral starting at 0 in the center,
	moving right first and then counterclockwise (OEIS A274641 layout).
	Black and Red take turns, Black first.
	- On Black's turn, place a knight on the smallest unoccupied cell
	that is NOT attacked by an existing Red knight.
