I drove up to see family over the long weekend, the better part of four hours each way on motorways I've done a hundred times. There's a particular kind of nothing to that drive. The road demands just enough attention that you can't properly think, and just little enough that your mind wanders off without permission. I used to fill it with music. Lately I've been filling it with podcasts, and on the way up I worked through most of a back catalogue I'd been meaning to get to for ages.
It was one of those engineering interview shows, the sort where someone who ran infrastructure at a place you've heard of talks for an hour about a single outage. I won't pretend it was all gold. But there was one episode where the guest said something offhand about how their worst incidents were never the dramatic ones. Not the database falling over, not the data centre losing power. The ones that hurt were the slow, quiet degradations that nobody noticed until a customer did, the failures that didn't trip any alarm because no alarm had been written for a thing nobody imagined could happen.
I've written about exactly this before, in my own small way, and hearing a stranger articulate it on a motorway somewhere past Birmingham was oddly validating. There's a thing that happens when you take a problem away from the screen. I'd been chewing on a monitoring gap at work for a fortnight, the kind where I knew something was missing but couldn't name it. Somewhere around the third coffee stop, with the podcast still going and nothing to type on, the shape of it just arrived. Not the answer, exactly, but the right question, which is usually the harder half.
I don't think this is mystical. I think it's that a laptop lets you act before you've finished thinking, and the act feels like progress even when it isn't. Sitting in a car, you can't. You're forced to hold the whole thing in your head, turn it over, notice the bit that doesn't fit. By the time I arrived I had three lines of notes scrawled at a service station, and on Tuesday they turned out to be right.
The coffee on the way back was worse, the traffic was worse, and the second half of the podcast catalogue was distinctly mid. But I'd take that drive again happily. There's something to be said for a problem you are physically prevented from solving, right up until the moment you can.
The notes are still on my desk. I keep meaning to throw the scrap of paper away and I keep not doing it.
