Building made me switch from Claude Code to Codex. Claude’s token usage was too expensive for my workflow. GPT-5.6 Sol + Codex lets me focus on building instead of watching usage limits. Loving it so far! 🚀 @OpenAI @thsottiaux

做了一个在线反应、记忆与专注力测试网站 最近做了一个叫 [PickTests]( https://picktests.com/) 的在线测试站。 反应时间、序列记忆、瞄准训练这些东西,网上其实已经有很多了。真正让我想重新做一遍的,是不少页面要么堆了很多不必要的内容,要么广告和装饰比测试本身更抢注意力,到了手机上也不一定顺手。 所以我给这个项目定了一个比较克制的方向: 不急着增加更多测试,先把每一个已有的测试认真做好。 目前上线了 6 个测试: - 反应时间 - 瞄准训练 - 序列记忆 - 数字记忆 - 多目标追踪 - 斯特鲁普测试 首页:[反应测试]( https://picktests.com/zh/) 网站使用纯 HTML 、CSS 和 JavaScript ,没有账号系统。成绩保存在当前浏览器,打开页面就可以开始。 我现在主要在调整这些细节: - 操作是不是足够顺手 - 测试节奏会不会太快或太慢 - 结果能不能一眼看懂 - 动效和反馈会不会太多 - 手机、平板和电脑上的体验是否一致 目前最想先做好的页面
