There isn't one — and the images that looked clean taught me more than the ones that didn't.

So the first honest measurement of my sky came off 68.8 mm of straightened paperclip — eleven aircraft heard, three of them placeable, and one NATO flight I listened to for three minutes and never managed to put on a map.

Its own data said 60% investigated, 20% piloted, 5% shipped — and the 80% who never piloted anything were counted as failures. Strip out the fake statistic and the real problem is still there, and it is not technology. It is how fast an organisation can change itself.

So here is ours — at least 20% of our week was going into revision notes, and the tooling we built gave one to two days of it back. One team, n=1, no control group, and including the part we have not solved yet.

A bot reviews it. Then the maintainer's review arrives — expert, accurate, and signed on its last line by a model. Last week I asked who is accountable. This week: can that person physically do the thing their signature assumes?

It did not touch the cost of standing behind it — and that sentence, not the typing, was always the expensive part. A walk up the supply chain where the liability evaporates at every step except the last one.

Four projects got real documentation sites this week — and the library went from v0.27 to v0.89 in five days. Here's what actually happened.

Then you export for Instagram and it looks like a completely different video. This is not your fault. This is color management, and it's genuinely hard.

Here's what happens when a DevOps engineer gets weekend hours and a opinions about their own homepage.

And then you realize the SDK is C++ and your soul is Go? Yeah, me too. Here's how I built a pure Go SDK for it.

Most people panic. Pilots just check which ILS category they're certified for. Let me explain why CAT III approaches are both terrifying and beautiful.

A hardware MCDU that connects to your flight sim and makes you feel like you actually belong in the cockpit. Spoiler: you probably still don't, but at least your desk looks cooler.
