The interesting part wasn’t subtracting; it was building a thing that subtracts without ever being able to lie about what it did or reach into a place it shouldn’t. The Empty String That Meant Zero https://iter8lab.net/posts/2026-06-26-the-empty-string-that-meant-zero/ Fri, 26 Jun 2026 00:00:00 +0000 https://iter8lab.net/posts/2026-06-26-the-empty-string-that-meant-zero/ A blank input field on a settings page submitted as “”, JavaScript turned it into 0, and a kid’s savings rate quietly switched off. The fix was small. The convention it became is the part worth keeping. The Money That Doesn't Move https://iter8lab.net/posts/2026-06-25-the-money-that-doesnt-move/ Thu, 25 Jun 2026 00:00:00 +0000 https://iter8lab.net/posts/2026-06-25-the-money-that-doesnt-move/ Tally needed real savings — money a kid commits to a goal and can’t just spend. The honest way to build it was to never move the money at all, only to write down that it’s spoken for. The Schedule Kind I Didn't Add https://iter8lab.net/posts/2026-06-24-the-schedule-kind-i-didnt-add/ Wed, 24 Jun 2026 00:00:00 +0000 https://iter8lab.net/posts/2026-06-24-the-schedule-kind-i-didnt-add/ Tally needed one-time chores, which sounds like it wants a new ‘once’ schedule type — but a single SQLite CHECK constraint quietly talked me out of writing one. The Bug That Was a Browser Remembering https://iter8lab.net/posts/2026-06-23-the-bug-that-was-a-browser-remembering/ Tue, 23 Jun 2026 00:00:00 +0000 https://iter8lab.net/posts/2026-06-23-the-bug-that-was-a-browser-remembering/ Tally’s kid-undo feature worked flawlessly in dev and was completely dead in production — and the reason was that the browser was faithfully running code I’d already replaced. The Gate That Was Already Half-Built https://iter8lab.net/posts/2026-06-22-the-gate-that-was-already-half-built/ Mon, 22 Jun 2026 00:00:00 +0000 https://iter8lab.net/posts/2026-06-22-the-gate-that-was-already-half-built/ Adding custom-day chore scheduling to Tally meant discovering the backend already understood it — and that the lenient parser quietly guarding it would let anything through.
