What it is — a personal assistant that's a folder on your disk, not an app: a very thin harness wiring Claude Code to Telegram, cron, and a knowledge base. You text it; it keeps your whole life in Markdown you own.
The bet — own the one layer that doesn't churn: your data. The model evolves, skills get superseded, the harness shrinks to glue — even which CLI you run it on swaps out — but your files and chat history stay put. Freedom isn't running the strongest model — it's that everything above your data is swappable.
Why Claude Code — open weights can't carry the judgment; ChatGPT/Gemini are closed products, not runtimes you own. Claude Code is stable, strong, ships the runtime as something you keep, has the most reliable tool-calling (and improving), and a flat subscription makes the dozens of tool-calls behind every reply essentially free.
The economics — one instance bills ≈ $970/week at list price. It runs on a $100/month subscription, and I run four. The model is the only cost — so it's the one knob you turn down: a cheaper tier, or point a cheaper API like DeepSeek at the same harness to push it lower still.

Heard that my former company's product was exhibited at CES. Happy that the remaining team members are doing great. This also reminds me of a framework (lapis) I worked with back then.

Recently completed a course on Web Application Architectures. I originally planned to borrow some architectural ideas and build a simple CMS application with Go, but after finishing the course, I found that ROR development efficiency is quite good and it auto-generates a lot of code.

Docker is a PAAS platform service software written in Go. It controls LXC services to provide hundreds or thousands of LXC containers on a single host, far more efficient than SAAS.
