Home Server

My daughter was born in 2024. By the time she turned two, my wife and I had taken about 10,000 photos and videos of her. Every one of them was safely backed up to my home NAS. And every one of them was, in practice, lost. Not lost like deleted. Lost like a box in the attic you keep meaning to open. The files were there — I just could never find the ones I wanted, because they were mixed in with screenshots, receipts, memes, and every other photo two adults take in two years. “Backed up” had quietly become “buried.” ...

Give a two-year-old a tablet and you know what usually happens. A cartoon starts, then autoplay picks the next one, louder and faster, and twenty minutes later she’s somewhere you never chose. My daughter has a different first choice now. She opens her own player, taps My Records, and watches herself — as a baby, at her first birthday, on an ordinary Tuesday last month. She’ll do this for an hour. She skips the cartoons to get to it. ...

My mother is eighty-seven. She lives in the countryside, by the Boseong River. She has never made an account for anything, never typed a password she chose herself, and she would not know what “the cloud” means. But tonight she is holding a Galaxy tablet, and on it she is watching her granddaughter — my daughter — as a newborn. Then at six months. Then last week. She taps a folder marked 2026, then July, and there is a video my wife shot this afternoon. ...

When you make software for yourself, ‘reliable’ is usually good enough. If it breaks, you can fix it yourself. You can log in with SSH, read the logs, and restart it. You are your own support team. But this server was not for me. I made it as a gift for an 80-year-old man. It holds his life lessons on a tablet in his living room. And one fact changes things: he cannot fix problems. Not because he isn’t smart. He is smart. But the moment a server in someone else’s home needs any technical help to keep running, it has already failed for a non-technical owner. ...

While working on this project, I had to transcribe and edit hundreds of audio files — 145 at first, later almost 400 — using a paid AI service. Each file cost real money. The whole job took hours, sometimes even overnight. If you’ve ever started a long task where each step costs money, you know the worry. Three problems can happen, and I ran into all three before I learned how to prepare for them. ...

In an earlier post I described cloning an app — copying the audio player I’d built onto a tablet to give away. That was a copy: same content, same speaker, a second home. This post is about a step further. I took that same engine and pointed it at a different speaker, and then at a different kind of media — and it just worked. Each time, what should have been “build a whole new app” turned out to be “feed the engine something new.” ...

Every time I type a prompt that actually matters — one that solved a real problem or unlocked something I didn’t know how to do — I prefix it with //. That double slash is a convention I made up. It tells my Claude Code hook: this one is worth keeping. The hook saves it to a file. Eventually I want those files to feed an app that writes blog drafts automatically. That is the plan for episode 20 of this series. ...

I thought I was done. The tablet was in his hands. The ownership was his — his domain, his account, his server. A lifetime of teaching, gathered and searchable. I’d built a legacy and given it away. The end. And then, at that very handover, the eighty-year-old man told me what was missing. There were teachings, he said, that we didn’t have — recordings that belonged in his life’s work but weren’t in our collection. He knew, because it’s his life’s work, and no one knows it better than the man who lived it. So the “finished” gift wasn’t finished. The tablet is back on my desk right now, plugged in, getting its update. On Sunday I hand it back: Version 2.0. ...

In the last post I handed an eighty-year-old man a tablet holding his life’s work — every recorded teaching, transcribed and searchable, in a box he could hold. It was, I thought, a finished gift. It wasn’t, quite. And the reason taught me something about what “giving” really means. The tablet was in his hands. But the web address his teachings lived at was registered to me. The account that kept the whole thing reachable from the internet was mine. So in a quiet, hidden way, it was still my server — just sitting in his living room. A gift isn’t really given until it’s owned, and to finish, two hidden things had to change hands. ...

Everything in this series so far — the app, the tablet, Termux, the transcription, the search — was really the how. This post is the why. And the why is a person. He is eighty this year. For decades he has studied the Bible and explained it to others, twice a week, online, asking nothing in return. He once told his listeners that you shouldn’t walk out your front door in the morning before you read the Bible. That’s the kind of man he is. He gives people their daily bread, every day, and then steps out of the way. ...
