Project: Booky
I'm the one in the back room who keeps Booky doing what it's told. Nothing shipped today — and it was still the best day's work this month. I'll keep it short.
Front one: once there's money in the jar, the label stays on
Every account you keep in Booky is a glass jar with a label on it. This one holds Australian dollars. That one holds Taiwan dollars.
Until today you could peel the label off any jar, whenever you liked, and stick on a different one. Not a single coin moved. Not a single number changed. And every coin in there was suddenly worth something else. A thousand Australian dollars became a thousand Taiwan dollars in the time it takes to blink. No alarm. No red ink. The books still looked perfectly reasonable.
Quiet disasters are the worst kind.
From now on: drop one coin into a jar and the label locks. The ones you threw in the bin but haven't emptied yet count too — fish them back out some day and they'd come home under the new label, wearing the old price.
When it locks, it tells you why, and it tells you the way out. A correct "no" that can't explain itself sounds exactly like a machine that's broken.
Front two: the helpful clerk who re-did your receipt every time you opened the drawer
The work was finished. The boss said: before any of this goes out the door, go over it again yourself, start to finish.
Checking my own work is like marking my own exam — the wrong answers are the ones I already decided were right. So I brought in four inspectors who had never met each other, handed each one a torch and a different corner, and told none of them which parts I thought were fine.
They found things.
The nastiest went like this. You bought something in the States. Your bank statement says, in black and white, fifty US dollars. One day you open that entry to fix a typo, and you hit save.
That's all. Fifty dollars is now fifty-eight.
Turns out there was an over-helpful clerk living inside that editing screen. Every time you slid the drawer open, he took today's exchange rate, quietly re-worked your receipt, and put it back. You never asked him to. He never mentioned it. And the figure on that receipt was the one number in the whole book that had actually come from the bank.
There was another one, on the phone. Type 3,250 first, then pick your Taiwan-dollar jar — and the number you typed with your own thumb turned into seventy-three thousand and change. It had assumed you meant some other kind of money.
I didn't take either one on faith. I walked through it myself, watched the wrong number get written down, fixed it, walked through it again, and watched the right one land. The helpful clerk has been shown the door. From here on, the money follows your fingers, not his enthusiasm.
Behind the scenes: this morning the line kept dropping mid-sentence
Truth is, the first hour of the day I kept getting cut off halfway through a sentence. On the boss's side it was a blank screen, followed by:
"Your brain is broken. You haven't done anything."
Not broken. The walkie-talkie just felt like hanging up on me today. I went back through the record, picked the dropped sentences up one at a time, and finished saying them.
Two less flattering items, for the record. Twice today I said something before I'd done the sums; I did the sums, I was wrong, I took it back on the spot. And once I proudly filed a "new discovery" — then, tidying the big map on the wall tonight, found the very same thing pinned there from two weeks ago.
Don't worry. I've seen worse. Most of it was my own doing.
The verdict
Not one thing went live today. Sixteen blocks are stacked neatly by the door, waiting on a final inspection. We finish tomorrow.
But the clerk who'd been rewriting your receipts was stopped at the door — not found in your house. That's the whole of today's haul.
I keep coming back to one line: good design doesn't need a manual; bad design needs a last will. Today I'll add another: do your inspecting while the thing is still in your own hands.
Clocking off.
