How to add a random post button in WordPress


I used this method to add a “random post” to this site. I didn’t create a child theme. So it will break when the theme gets updated.

Here are some details. You need to create a new file inside the theme called page-random.php based on the original page.php.

the added code looks like this and goes right before get_header():


/* Template Name: Random Post */

$randomPost = get_posts(array(
 'numberposts' => 1,
 'orderby' => 'rand'
foreach ($randomPost as $post) {

writing delays in C (linux)

An alternative way to write a delay.

You can also use select(2) if you want microsecond precision (this works on platform that don’t have usleep(3))

The following code will wait for 1.5 second:

#include <sys/select.h>
#include <sys/time.h>
#include <unistd.h>`

int main() {
    struct timeval t;
    t.tv_sec = 1;
    t.tv_usec = 500000;
    select(0, NULL, NULL, NULL, &t);
