222. Cassette Player 中
The cover photo shows a Sony integrated cassette/CD player I found last week. I bought 10 cassettes; I really love the texture and the retro feel of listening to music this way. I love it so much—one cassette every night feels great.

Mastra: An elegant TS AI Agent framework
https://mastra.ai/
This TS AI Agent framework, Mastra, is truly elegant. It’s been a long time since I’ve seen such a beautiful and concise library. It provides a memory framework, workflow execution, RAG, etc. I feel that for building low-code versions of AI applications, we still need a ProCode version for engineers to develop more customized AI apps.

An open-source Cursor-like AI code editor. The interaction is very similar to Cursor; you can use any model, control your own data, and since it’s a VS Code fork, you can migrate configurations seamlessly.

I’ve been reading this lately; it’s a very readable investment learning book. Highly recommended!
”Investors would be much better off if they simply bought and held an index fund based on a broad market index, rather than trying to buy and sell individual stocks or active management funds.”
How to improve product conversion while maintaining a good user experience?
https://www.uisdc.com/ux-rights-balance
User guidance shouldn’t be a “gentle trap” but a “clear invitation.” Product design shouldn’t be about “making you take the bait” but “making you willing to stay.” In this era where experience is king and trust is scarce, designers should ask themselves: Is this path fair? Does the user understand and agree? Can they change their mind at any time? If the answer is “yes,” you’re doing “benign design.”
