Daily Reading List – September 22, 2025 (#632)

First workday in Seoul is complete. I tried to wear myself out on Sunday by walking around for hours, but still somehow woke up wide-awake at 3am. But a great day, and customer visits up tomorrow. Meanwhile, a fun reading list!

[article] The Purpose of Prototypes. What’s the purpose of a prototype? Your answer may be different from Marty’s, and it’s worth reviewing his.

[article] Is Your Startup Idea Any Good? Borrow These Validation Tactics from the Founders of Linear, Mercury and More. Somewhat related to the previous post. How are you vetting your ideas and finding out whether it’s worth building out?

[blog] The quality of AI-assisted software depends on unit of work management. Read this. I think it presents such a strong point when thinking about AI’s role in software dev, and how to find the right unit for work.

[blog] How Agents Think. Do LLMs “think” like a human brain does? I don’t think so. But patterns like the ReAct loop combined with reflection looks a LOT like how we approach problems.

[blog] AI Was Supposed to Help Juniors Shine. Why Does It Mostly Make Seniors Stronger? I get the hypothesis. Our own data isn’t bearing this out. Earlier-career devs seem to be using it more often to good results.

[blog] 2-Minute ADK: Speed Up Your Agent with Parallel Tools. Simple post, but great reminder to optimize everywhere.

[blog] I think “agent” may finally have a widely enough agreed upon definition to be useful jargon now. Saying “an LLM agent runs tools in a loop to achieve a goal” is a solid way to describe what an agent is.

[blog] This Week in Gemini CLI (vol. 4). For those who don’t want to wade through release notes, posts like this are super useful.

[blog] Achieve agentic productivity with Vertex AI Agent Builder. Everyone is going to be offering you platforms to build and run agents. Be clear on what you’re looking for.

[blog] How to Evaluate AI Coding Tools for Your Enterprise. It’s tough to mentally organize all the different AI tools out there, so this categorization works as well as any.
