A note for grown-ups

Knowing and acting are two different permissions. Everyone can know there's a party (the answers, shared widely). Only a few can do the risky jobs, like the oven or the car (few can act). One person says yes to the plan (one owns the call). The surprise itself stays need-to-know (the dangerous details, shared narrowly). And every note has a name and a time on it, and runs out, just like a claim someone stands behind.

A family huddles around a kitchen table with a party plan, everyone whispering shhh, while a balloon floats by THE PLAN Party Saturday! SHHHH!
It's Grandma's birthday on Saturday. We're throwing her a surprise party. Who gets to do what?
Watch it first: one party, lots of helpers, one secret.

A big plan works best when knowing and doing are two different things. Lots of people can know. Only a few can do the tricky jobs. And one person says yes.

A calendar with Saturday circled and five happy faces who all know SAT EVERYONE KNOWS
Lots can know. Everybody knows there's a party Saturday. That helps: nobody plans a sleepover that day.
Only a grown-up uses the oven, and only one person drives to get the cake GROWN-UP 1 DRIVER
A few can do. Only a grown-up uses the oven. Only one person drives to get the cake.
Three ideas on sticky notes and Mom giving one big thumbs up to the plan PIZZA?TACOS?BOTH?! YES!
One says yes. Everyone gets ideas. Mom makes the call. One yes, not five.
A locked secret envelope with the guest list and the cake, and a little cousin outside it TOP SECRET PARTY? YAY!
The surprise stays secret. Who's coming and what the cake looks like? Need-to-know. The little cousin who can't keep secrets gets the party, not the plan.
Two sticky notes on the fridge, each with who and when: dog fed by your brother at 5pm, good until breakfast; balloons bought by Dad on Friday, good until they pop Dog fed βœ“your brother, 5pmgood untilbreakfast Balloons βœ“Dad, Fridaygood untilthey pop WHO?WHEN?UNTIL?
Every note gets a name and a time. "Dog fed" from yesterday doesn't mean the dog ate today. Notes run out.
Surprise! Grandma walks in and everyone jumps out. Underneath: lots can know, a few can do, one says yes. SURPRISE!
It worked. Lots of helpers, a few doers, one yes, and the secret stayed a secret.

Lots can know. A few can do. One says yes. That's Dad's job, but for computers in big companies.

Quick question: why does a note need a name and a time on it?

Tap to see

The name tells you who to ask. The time tells you when it's old news. If the note says "dog fed, 5pm" and it's morning, the dog is hungry again. Grown-ups forget this one too.

πŸŽ‚ Print the surprise party and stick it on the fridge (where Grandma won't look).

Too easy? Read the grown-up version.

TL;DR

Matt thinks out loud here about technology, mostly how teams decide what to build, fix and protect.

The first series argues that security gets better fastest when the teams that each hold part of the answer share it earlier. Part 2 says most critical findings aren't: seven questions tell you which, and the answers live with other teams. Clay first, chisel later is about roughing out the whole thing before polishing the parts.

Every piece says how much AI helped, and the site is built in the open: a roadmap with a big picture (only Now is a promise), a changelog with a monthly review, and the product work itself, like Operatie Klompje, a postcard-sized product for one customer: his mom.

There's also an Arts and crafts wall, because not everything has to be serious. The discussion happens on LinkedIn.

Streng geheimOperatie Klompje

Postcard front: Mama in a lace cap, apron and clogs, proud of little Machoo.
The customer: my mom. Small, even in clogs. Giant courage, and giant worry. Most of what she knows about my work comes from the news.
