To start with, it is not easy for greenhands to write out an appropriate buildfile for hexo in docker.
As is suggested, Alpine is a minimized Linux environment designated for docker images, which appears to be tiny in size.
Yet it is tough to upgrade node and npm if the pulled version of alpine is outmoded, so take a look when choosing the right origin of the mirror.

这门课程在整个本科CS的课程体系中似乎没有多少地位，但在研究方面是相当有分量的。

然而难以听懂、吸收。

正如葛洪伟老师所言，如果这门课讲述的是喜闻乐见、生动有趣的轶事，普罗大众都可旁听，没有门槛，那么就不能产生足够的价值。
这门课必然是枯燥乏味的。
