AI Log 1: Claude vs GPT — A Head-to-Head Agent Delegation Experiment
I pitted Claude Opus 4.7 via Bedrock API against GPT 5.5 — not as chatbots, but as agentic supervisors. Each was given the same task: write a delegation prompt for a coding agent, dispatch it, review the result, and iterate to correctness. Same codebase. Same delegate model. Same constraints. Only the parent agent changed.

Book Log 3: 《文明的滴定》与个人科学史观

这本书是我偶然看一本历史穿越小说得知的，通过这本小说我知道了谁是苏颂，谁是韩公廉，沈括除了写《梦溪笔谈》还具体干了啥，也知道了在几百一千年前的中国历史中一些神奇的发明。作为完成了九年义务教育的我来说，谈及开封只悉晓清明上河图，古代科技只认四大发明，这在现在看来无疑是可笑的。
