This heuristic can be illustrated by the following design. Let’s say we have an application that generates a report, compresses it with zip, and saves it to the disk. With this heuristic in mind, we wouldn’t want the report generation to depend on the zip algorithm. A change from zip to LZMA algorithm shouldn’t affect the report generation. Likewise, the compression module shouldn’t depend on the file storage module. If we follow that heuristic, we will be able to change file storage to network storage without affecting compression or the report module. (By the way, this design might not be ideal, for instance, these tasks are too small to be modules, but I hope it conveys the meaning of this heuristic).

机器先看的是结构。YouTube的内容长得都差不多：有标题、有简介、有标签，有时还有清晰的时间轴和章节。标题往往就是一个问题或主题，简介相当于摘要和补充说明，标签和分类是现成的语义标记，章节和时间点把一条长视频切成若干段。
