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. ...

My three-year-old daughter would press play in Kids Player and wait ten seconds for the sound to start. That wait is why I upgraded my NAS from 2 GB to 10 GB of RAM. So: did it work? The honest answer is two answers. On paper, the upgrade was a triumph. In daily life, it made things about one second better. Both are true, and the gap between them is the most useful thing I learned. ...

In the last post, I ordered an 8 GB RAM module for my Synology DS224+. I paid ₩76,000 (about $55) instead of ₩68,000 (about $49) for a bulk one, because I wanted to avoid a used or unpackaged module. Then it arrived. A plain brown box. Inside, a bare green board wrapped in a sheet of foil and some bubble wrap. No Samsung retail box. No sealed blister. It was bulk after all. ...

There is a 1974 German theology book that exists in almost no library. One copy lives with its owner here in Korea. He wanted it translated into Korean. I offered to help. First step: get it scanned properly. I visited a professional scanning company. They said the book needed to be taken apart — pages separated, binding cut — before they could run it through their equipment. I relayed this to the owner. He said: do not cut this book. The scanning company said: then we cannot help you. ...

Here’s a question that sounds odd at first. Could the cheapest, smallest, quietest computer in your house be your home server? Not a Raspberry Pi. Not a NAS. Not an old laptop on a shelf, fan going, getting warm. I mean an ordinary Android tablet — the kind you’d hand a three-year-old to watch cartoons. It turns out it can, and I’ve been running one this way for a while. A $100 tablet sits in my home right now, plugged into the wall. It runs a real Linux server that serves audio to a web app, over its own secure web address. It’s silent, about the size of a paperback, and it uses very little power. I’m as comfortable leaving it on as I am leaving my phone on. ...

The official specs for the Synology DS224+ say the maximum RAM is 6 GB. This is made up of 2 GB built-in and one 4 GB SO-DIMM module. Still, I ordered an 8 GB module. I will tell you why and how I made that decision. What AI Tools Said I asked both Gemini and Claude Code about compatible RAM for the DS224+. Both gave the same answer. They said officially, the maximum added module is 4 GB (for a total of 6 GB). But they also said what actually works is different. Community users have installed 8 GB modules and are successfully using 10 GB of RAM. There is no guarantee, but there were no reported failures either. ...

For months, my home server ran nine apps on 2 GB of RAM. I kept expecting something to break. It didn’t. Load average sat around 0.2. Apps loaded. Nobody complained. I started to think 2 GB was just enough, and left it at that. Then one afternoon my three-year-old pressed the play button on Kids Player. Nothing happened. She pressed it again. Still nothing. About twelve seconds later, the audio started. ...

You’ve probably felt this. Someone mentions a technology — Cloudflare Tunnel, RAG, Termux, vector search — and a small door closes in your head. “That sounds powerful,” you think, “but it’s not for me. I’m not an engineer.” For most of my life, that feeling was right. Knowing the name of a technology got you almost nowhere. Between the name and a working result there were months of study, and a level of skill I was never going to reach. ...
