Automating my monthly net worth tracker

Wed, 12 Aug 2026 00:00:00 +0000

Overview

I track net worth every month across more than 20 accounts spread over three countries. Doing that by hand in a spreadsheet meant re-typing balances, occasionally fat-fingering a number, and having no real record of what the sheet looked like before I overwrote a cell. income_statement is a Python script that automates the accounts it can and makes the manual entries it can’t avoid fast and safe.

Automating the boring half of my backup process

Wed, 12 Aug 2026 00:00:00 +0000

Overview

My critical file backup process has a lot of steps, and most of them are exactly the kind of thing that’s easy to skip when you’re doing them from memory once a month: export the Drive folder, export three spreadsheets, export contacts, then remember to actually check that each file showed up and isn’t empty. backup_process automates the parts that are purely mechanical and leaves an interactive checklist for the parts — password manager exports, KOReader settings, Pleco settings — that genuinely need me at the keyboard.

Synthesizing Obsidian periodic notes with Claude Code

Wed, 12 Aug 2026 00:00:00 +0000

Overview

I keep a daily note in Obsidian, but I’d never reliably sit down and roll those daily notes up into a weekly summary, let alone a monthly, quarterly, or annual one — it’s the kind of synthesis that’s valuable in hindsight and easy to skip in the moment. periodic_notes uses Claude Code to write that rollup for me, built from the notes one level below it: a week from its 7 daily notes, a month from the weekly notes whose Monday falls within it, a quarter from its 3 monthly notes, a year from its 4 quarterly notes.
