cochleari_majoron There are only twelve 4x4 sudokus (and a cool trick for finding minimal subsets)

I’ll plug a 4x4 variant sudoku generator that Claude put together a few months ago.

cochleari_majoron Show HN: Got sick of ads, so I made my own logic puzzle site

I'll plug a little page that I (well, Claude) put together for bite-sized 4x4 Sudoku puzzles mixing popular variant constraints: https://yakymp.github.io/sudoku4x4/

cochleari_majoron The legal rule that computers are presumed to be operating correctly (2022) [pdf]

“Which would cause the first reading to have more weight than successive readings”, funny enough looks like the opposite of what’s going on.

cochleari_majoron Game of Life, simulating itself, infinitely zoomable

I find the following asymmetry interesting: if you pick a random spot and start zooming out, you will pass through interiors of both dead and living cells in some ratio. But if you start zooming in, pretty much all of the cells you pass through will be dead.

cochleari_majoron Pareto Front Sort for Python

For low dimensions, it might be useful to look at the convex properties of the Pareto front. If a point P is on Pareto front, it is not in the interior of the convex hull of undominated points. In two dimensions, one can compute the convex hull of N points in O(N log N) time. This typically allows for faster Pareto front computation, but not in the worst case.

The author claims the same thing is true of software, but not with software itself.

This is great article. When I read "Taught in 30 Minutes" I was amazed at how the author seems to think that it was a "fantastic story" that was written in an unrealistic way - that the author has been able to write his book on his own (yet untrue). The author doesn't seem to be aware of the actual circumstances behind the creation of a book.

Great post. This is really the kind of article I don't think the author talks about in his blog post.

TL;DR - the world is everywhere.

I was very disappointed with the title, but here we are.
