I keep seeing people share vibe-coded apps built on TypeScript/React + Supabase — seemingly the default recommendation from Lovable or Cursor. As a Clojure programmer, I can't stay quiet about this. In an era where AI agents are deeply embedded in the development workflow, that choice carries structural hidden costs that almost nobody is talking about.

Context Window Is the Bottleneck, and Framework Design Determines Burn Rate

When I told others that I am a Clojure programmer, they responded apathetically. Why so many people in Taiwan never heard of this great programming language? One day, an idea occurred to me that how about teaching some students?

The background of this post

I began to use Datomic seriously in my project at work from February 2019. I encountered certain performance issues and I solved them through disk cache and LU cache.

Background

I needed to do eight Excel ETLs at my project. At the beginning, I just implemented some of the ETLs without any design. I did not even implement schema validation, and then I felt the pain soon. After several re-writing, I abstracted out some idioms and patterns for ETL.

I live in Taiwan and I can not find Clojure jobs here. Although the first legal gay wedding in Asia took place here, it seems that the real programming language innovation still needs some evangelists to spread it. Therefore, I decide to create Clojure job by myself. In January this year, I had a chance to develop enterprise software for a big company, and I chose Clojure as my primary technical stack.
