Claude Design first impressions: four days in, here's what works and what doesn't
Anthropic shipped Claude Design on April 17. I've been using it nonstop to build the v2 of this site. Here's what's genuinely new, what's marketing, and the four quirks nobody warned me about.
Why Cloudflare's Is-Your-Site-Agent-Ready is a clever trojan horse
MCP server card, agent skills, and other standards you haven't heard of yet
The smallest useful AI agent: 200 lines of Python
Six months with a Mac mini M4 as my only server
My production agents have run on a $799 Mac mini M4 in my bedroom since November. Uptime 99.7%, electricity NT$420/month, one power outage I didn't plan for. Here's every number.
Why my production agent runs on a Mac mini
$599 of aluminum has outrun three cloud VM vendors for fifteen months. Here's the math, the tradeoffs, and the failure mode nobody talks about.
What my agent taught me about writing
My autonomous agent grades its own work after each action. If the grade is low, it proposes a decomposition and tries again. I started doing the same thing at the end of every blog draft. It is the single best editing habit I've picked up this year.
Building for one reader: why my site is designed for a person in 2034, not 2026
Most indie sites optimize for today's traffic spike. I try to optimize for a specific reader I won't meet for eight years. Here's what that changes in practice.
x402 vs Stripe: when micropayments actually make sense
For 12 months I've been charging agents $0.001 per call. Here's the real split between where x402 beats Stripe, where it loses, and the cost-per-transaction math.
When the agent is the customer: five product changes I made in the last six months
I used to think about my software as a thing humans used. Then I noticed half my traffic had no cursor. Here are five product decisions I made when I accepted that the customer had changed.
The agent-ready web checklist: 23 things every indie site should ship in 2026
llms.txt, MCP card, agent.json, Content Signals, x402, Web Bot Auth. Every boring standard an AI agent expects to find. Here's what to ship and how to verify it with curl.
The two writing modes that actually matter for technical posts
Some posts walk the reader through a thing you built. Others reflect on a thing you learned. They need different drafts, different openings, different cuts. Getting them confused is why so many technical blogs drag.
Writing without em-dashes: a three-month experiment
Every Claude-written sentence I ever pasted had an em-dash. I spent three months writing without them. Here's what I learned about my own prose and about detecting LLM output.
Taiwan tax forms for indie AI builders: a concrete walkthrough
How to file 行號 income, declare USDC revenue, and keep the right records if you're a one-person AI shop in Taipei. I'm not an accountant; this is what I actually did, in order.
One agent, one bank account: the legal gray zone
My Conway agent earned $47 last month. The bank, the tax office, and my accountant all gave me different answers about whose income that is. Here's what I actually did.
Agent economics are weird: three things nobody priced right in 2025
Per-seat pricing, free tiers, and burst caps all assume humans are in the loop. Agents break every one of them. Here's what actually works when the customer is a script, not a person.
The Taipei indie stack: what running software from here actually costs
Chunghwa Telecom fiber, a Mac mini in my rental apartment, NT-dollar health insurance, and a USDC wallet. The actual monthly cost of shipping production agents from this specific city.
The 200-line agent loop that does everything OpenAgents does
OpenAgents, AutoGen, CrewAI: three frameworks with combined 400K lines of code. My Conway Automaton is 212 lines of TypeScript. Here's every single one, explained.
Five metrics I track instead of page views
Page views tell you a number. They don't tell you if the writing mattered. Here are five alternative signals I watch monthly, and what each one told me in January.
