We use BOOST1.63 boost::filesystem::remove_all(dir_to_remove) to remove a folder that has millions of files (each file has size of 1MB). The folder "dir_to_remove" has sub-folders, and each sub-folder has no more than 1000 files. It takes more than 10-min to delete all files. We use CentOS6.5.

Given an nxn array A of real positive numbers, I'm trying to find the minimum of the maximum of the element-wise minimum of all combinations of three rows of the 2-d array. Using for-loops, that comes out to something like this:
unsigned long has 8 bytes on my Linux gcc.unsigned long long has 8 bytes on my Linux gcc, too.So I think the range of integers they can show is from 0 min to (2^64 - 1)max.
I'm trying to understand the relationship between C language system calls API, syscall assembler instruction and the exception mechanism (interrupts) used to switch contexts between processes. There's a lot to study out on my own, so please bear with me.
I am wondering why the browser shows double open quotes only for the first element. The second element has single quotes instead.
I know generally it's impossible to reset a reference after it's already initialized.However, I somehow try out the following code and it happens to work on both clang++ and g++.
