I just completed "Reactor" - Day 11 - Advent of Code 2025 #AdventOfCode adventofcode.com/2025/day/11

This was one where my approach was right, but my desire for output defeated any attempt at a properly optimized algorithm.

I just completed "Factory" - Day 10 - Advent of Code 2025 #AdventOfCode adventofcode.com/2025/day/10

I thought about coding up something to minimize the function, but took the opportunity to learn a new tool instead.

Plotting the input made the answer feel obvious, I just kept getting all the math wrong.

I had some trouble with semantics on part one, but modification for part two was trivial.

I just completed "One-Time Pad" - Day 14 - Advent of Code 2016 #AdventOfCode adventofcode.com/2016/day/14

This one was frustrating. My code gave the wrong answer. Code from two different users on Reddit gave the same wrong answer. Finally, a third user's was right.

Why? I don't know yet.

Way back in 1947, Alan Turing had thoughts on how AI would influence the demand for skilled labor.

(via Matteo Pasquinelli 2023 _The Eye of the Master_)
Roughly speaking those who work in connection with the [automatic computing engine] will be divided into its masters and its servants. Its masters will plan out instruction tables for it, thinking up deeper and deeper ways of using it...The masters are liable to get replaced because as soon as any technique becomes at all stereotyped it becomes possible to devise a system of instruction tables which will enable the electronic computer to do it for itself. It may happen however that the masters will refuse to do this. They may be unwilling to let their jobs be stolen from them in this way. In that case they would surround the whole of their work with mystery and make excuses, couched in well chosen gibberish, whenever any dangerous suggestions were made. — Alan Turing (1947) Lecture on the Automatic Computing Engine

Going through my father’s things I found my grandmother’s report card, circa April 1916. She got a poor mark in “deportment,” which is what they called “Social emotional growth” then. Her parents were probably mad — at the mark, not at the concept of deportment, because they weren’t morons.

Tech brains broken part 1000000000 (this lady is a partner at Andreessen apparently)
My son came home with a Pre-K report card; I read it and was thrilled. My husband read it and was baffled. I read it and anchored on the lines that really matter: "He excels quickly in all his math assignments and has mastered the math and reading concepts presented." My husband focused on the extra full page on "social emotional growth" commentary and looked confused the whole time. "What does any of this mean?" "Nothing," I said. "Ignore it." And then that evening we explained to our son the lesson that is going to get him through his life: "People will put up with many things if you are excellent at math. You're so good at math. We're proud of you." And that was that. There are many important posts going viral today about the tragedy of young men. Combatting the systems that seek to destroy their nature begins in the home, and it begins young. I don't care about the "social emotional growth" of my sons because I know what values we're instilling in them. Telling them what really matters begins with dad and mom. The family can be a reprieve from all the nonsense. It requires constant vigilance, but it's the first step in preparing them for the madness outside. 8:09 AM • 11/11/25 • 1.3M Views
