The 1904 Japanese budgeting method, now on iPhone

What it does

Kakeibo is the Japanese household ledger Hani Motoko published in 1904. Four spending categories, one savings promise made before the month starts, four questions answered when it ends. The app does the arithmetic and leaves the reflecting to you. Free tier.

Kakeibo is the Japanese household ledger Hani Motoko published in 1904: four spending categories, four questions, and a monthly reckoning you write by hand. This site does the arithmetic with you and leaves the reflecting to you.

Four spending categories, one savings promise made before the month starts, and four questions answered when it ends. Published in 1904, and this site has done the arithmetic around it. Live arithmetic, running in your browser. The split is our suggested starting shape for a blank ledger, not a rule kakeibo ships, and every calculator here lets you move it. Nothing on this site repeats the claim that kakeibo saves 20 to 35 percent. We went looking for a primary source and could not find one. Few enough to hold in your head at the counter, which is where the decision actually gets made. 130 everyday expenses, each argued into one envelope, with the awkward cases settled separately rather…from kakeibomethod.com

    Hello HN! I found that picking out plausible but diverse skin tones for my digital art and game development projects was kind of difficult, and I got curious about if there was a way to define a color space that made it easy. I've built a color picker and procedural generation algorithm based on the space as well as a bunch of other fun js features and demos throughout the page that use the equations. If you find it interesting, I have lots of explanations of how I built it and what properties the space has. The methodology might be a bit shaky, but hopefully the result is as helpful for…

  • I trained a 125M-parameter transformer to autocomplete piano performances in real time (~108 notes/sec on an iPhone 15). The idea is basically GitHub Copilot or Tabnine, except instead of prompting it with code, you prompt it by playing a few notes on a MIDI piano. The model then continues what you played, entirely on-device. The app is free if anyone wants to try it. Happy to answer questions about the model, training, Core ML, or the many things that didn't work.
