虽然它目前还是测试版，图标像个工程蓝图，发热也有点明显，但好就好在 Project Indigo 目前完全免费，所有功能都可以直接使用，体验一下将手机变成专业相机，绝对值得值得尝试（当然，你可能需要个外区 App Store 账号，不过这很好获得。）
书中穿插了不少诙谐故事、民俗谚语，调和了学术理论的严谨与抽象。譬如“韩延寿巧断争田案”中的“县官误解风土”，某郡太守向一县官问话：“此地风土如何？”县官不知道“风土”指的是风俗习惯，于是答道：“风不大，土沙也不乱飞。”太守又问：“黎庶还好吗？”县官更不懂“黎庶”指的是老百姓，回答说：“梨树今年开花少，估计要减产。”看似闲笔，实则暗合执法施政必须考察风土民情的道理，让读者在会心一笑中领会中华法系的吏治知识。

When shoes slide across a floor, wave-like deformations of the sole can generate squeaking. The pitch of the squeak depends on the rate at which deformations are generated.
