I am confused, because
Org. apache. hadoop. filecache-*, org. apache. hadoop
I don't know why the package is empty. Should the package name be a class for managing File Cache?

Org. apache. hadoop. fs-Seekable, org. apache. commons

why org 07c00h?
A lot of people are asking questions about this line after they read the book, "write their own operating system" or their second edition.
This question is explained in the book by the author:
Tell the compiler that in the future our program will be loaded into the 07c00 for execution.
To tell the truth, "write your own operating system" this book is really good, I do not admire the author's level, but the author's perseverance, can p
