I made an intake form people can complete by talking on the phone Forms are good at collecting structured answers and terrible at getting the whole story.

最近用 Codex 做了一个 3D 骰子! 最近做了一个很小的网页工具:3D 骰子。 做完后有点纠结: 这种小工具到底应该保持极简,还是把常见功能都补上? 抛骰子: https://wheelpage.com/zh/dice-roller/ Dice Roller: https://wheelpage.com/dice-roller/ 现在功能很简单:打开页面,点一下,骰子滚动,然后给出结果。 一开始觉得骰子就是 1 到 6 的随机数,应该很好做。 但做的时候发现,如果只是直接显示数字,又不太像“掷骰子”;做成 3D 动画,又担心有点多余。 现在倾向于先保持简单,打开就能用,不加太多设置。 顺便也做了一个抛硬币页面: https://wheelpage.com/zh/coin-flip/ 它和骰子类似,都是临时做随机决定的小工具。
