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. ...

I built an audio app once. Then I built the same app again — and the second time took an afternoon. Not because I’m fast. Because I didn’t really build it again. I cloned it. I took the thing I already had, copied it onto a different machine, pointed it at a different home, and turned it on. That sounds ordinary until you notice you can’t do it with the apps you use every day. You can’t clone Netflix onto a relative’s device. You can’t copy your Spotify and hand it to a friend. The big apps are sealed boxes you rent access to. But software you build is yours, which means you can make copies of it the way you’d copy a key. ...

My daughter is three. She loves one specific playlist of Korean children’s songs, and she likes it best when it plays from a small JBL Bluetooth speaker tucked under her stroller. We walk the neighborhood for about an hour most evenings. I put on her folder, the first song starts, and we go. Thirty seconds later, my phone screen goes off. One more song plays. Then it stops. I have to unlock the phone, tap the next song, put the phone back in my pocket, and keep walking. A minute later, same thing. ...

A pile of audio is a black box. You know the teacher said something about a certain verse. You can almost hear it. But it’s somewhere inside hundreds of hours of recordings, in one lecture out of hundreds, at a point you can’t remember. Without a way to search, those recordings are write-only: you can keep adding to them, but you can never really get anything back out. The bigger the collection grows, the more it buries. ...

My daughter is three. My phone takes about 6,000 photos and videos a year — maybe more. I don’t have 6,000 interesting shots. Most of it is accidental taps, blurry motion, seventeen near-identical photos of the same bread I was about to eat. But somewhere in that pile are the clips I actually care about: her first steps, her laughing at something she found hilarious at the time, moments my wife and I know we’ll want to see again when she’s older. ...

My wife listens to a Bible teacher every morning. After I built her an app to make that easier (the first post in this series), she asked for one more thing. It turned out to be the hardest part of the project. Could we also read his teachings, she said, not just hear them? Reading helps her study. She wanted the words on a screen. “Sure,” I thought. “I’ll just turn the audio into text.” How hard could it be? In 2026, turning speech into text is mostly a solved problem. ...

My three-year-old daughter has a favorite show. Baby Shark. She could watch it every day, and often does. Last week, I showed her something new. Fifteen short videos of herself as a baby — the first year of her life, played one after another. She sat still for one hour. Smiling, then laughing out loud, then quiet and focused. She didn’t ask for Baby Shark once. My wife was watching from across the room. She didn’t say much. She didn’t need to. ...

I keep forgetting how to reconnect my NAS folder in Windows Explorer. Every time, I end up asking an AI to walk me through it again. So this time I’m writing it down — for myself as much as anyone else. And then today, the usual steps didn’t work. The folder was gone, and reconnecting it failed too, even though the laptop was on the same Wi-Fi as the NAS. That turned into a longer fix. I’ll cover both. ...

In the same week, I bought two computers from the same company. One was a Lenovo laptop — a nice everyday machine I picked up at Costco. The other was a Lenovo tablet, bought to be a small home server. They had the same 128 GB of storage. And the tablet cost less than a third of what the laptop did. That gap made me stop and think. Not because the laptop was a bad deal — it wasn’t. But it showed me something I’d never really thought about. For the job of being a server, most of what you pay for in a “real” computer just sits there unused. ...
