Anna Havron: a Fountain of Wisdom
@857@fedia.social shared a link to an answer to a reader question about open and closed lists on Analog Office. I found it intriguing and went on a wandering binge of a few dozen posts throughout Analog Office and her personal site at annahavron.com. Here are some highlights.

Friendship Ended With Gas Stoves, Induction Stoves Are My New Best Friend
Soon after my parents replaced their temperamental electric cooktop with a gas cooktop, I decided that gas stoves were the best and made it one of my goals to own a gas stove one day.

Getting LXC To Work
In my last post, I tried and failed to set up LXC for deploying software. I revisited the setup later on and got things to work, and this is what I did. Unfortunately, I didn’t start from scratch, so this will be of limited use to anyone trying to set up LXC themselves.

Advent of Code 2020 Day 10 Part 2 Generalization
I fell down a bit of a rabbit hole after I finished part 2 of day 10 of Advent of Code. My solution broke the problem into several instances of a slightly different sub-problem. These were simple enough to reason about by hand, which let me come up with a formula for the smallest few (\(n < 4\)). I knew the formula didn’t generalize to bigger examples, but the puzzle didn’t require any that weren’t covered by my formula. It bugged me that my solution wasn’t general, so after solving the puzzle, I set out to determine a solution to the sub-problem for all \(n\).

How Many Degrees in a Sphere?
I was listening to something that talked about, “looking in every direction—360 degrees around”. This bothered me, because 360 degrees isn’t every direction. Up and down are missed, for example. This got me wondering: if there are 360 degrees in a circle, how many are in a sphere? Of course, for a sphere, they will have to be square degrees instead. \( \def\dd{\mathrm{d}} \)

Code 128 Barcode Optimization, Part 2
My last post described the code128 barcode format and how to optimize the encoding of a barcode payload for minimum barcode length. This post describes how I implemented the described algorithm in rust. Please read the previous post to understand the problem and context of this solution.
