ballin#One night — after a glass of wine — I had another idea: one modern trick with ASCII art is the use of Braille unicode characters to allow for very high detail. That reminded me of ball physics simulations, so what about building a full physics simulator also in the terminal? So I asked Opus 4.5 to create a terminal physics simulator with the rapier 2D physics engine and a detailed explanation of the Braille character trick: this time Opus did better and completed it in one-shot, so I spent more time making it colorful and fun. I pessimistically thought the engine would only be able to handle a few hundred balls: instead, the Rust codebase can handle over 10,000 logical balls!

抖音和小红书相继加码长图文，本质是围绕优质创作者和用户停留时间的争夺。只不过前者选择横向进行扩张，在短视频信息流中插入风格截然不同的长图文内容；而后者则是在原有的图文形式上纵向深挖，通过AI工具降低内容的创作门槛。从更深层看，这也是内容平台进入存量竞争后的必然选择。
