老的本来准备卖掉的M4的Mac mini最爽的用法：
拿来当自建CI机，以及给Agent跑各种自动化端到端测试，以前一直用Github跑CI，但是Agent太喜欢提PR了，即使开了会员，有时候每个月还是能多花二三十刀。。。
现在速度快，并行还爽...
24小时待命，闲的时候，还顺道给自己的Agent当专用机，所有的Chrome啥的都给他登录好，飞书CLI也弄好，扔给Agent自己全自动随便去玩，直接焕发第二春了。
Khazix repurposes an old M4 Mac mini as a self-hosted CI runner and agent machine
AIKhazix says his M4 Mac mini, originally meant to be sold, now runs self-hosted CI and end-to-end tests for his agents. He says this avoids the extra $20 to $30 a month he spent on GitHub CI when agents opened too many pull requests.
