    Why is this thing so slow? It took me five minutes to store a 400 line text file!

    Well, this is just an initial prototype, and don't worry, there's always Moore's law!

    Pi 是不是正规数现在还没有证明吧。所以这个文件系统能否存储任意文件还存疑…(当然应该也没人指望拿它干正事儿

    如果数据在pi中的位置足够后面,存储位置也会是巨大的开销吧(克拉夫特不等式)(好吧, [好多] 年已经过去了)
    话说这种东西拿来骗star还是很不错的

    平均存储长度真的可以小于原始文件长度吗

    @sinxccc 它会把一个文件分小的 chunks,寻找一个短的数列比较容易吧,而且有限数位的组合是有限的,所以理论上应该可以存储任意文件 “we all know that it can take a while to find a long sequence of digits in π, so for practical reasons, we should break the files up into smaller chunks that can be more readily found.”
