There are three easy to make mistakes in go. I present them here in the way they are often found in the wild, not in the way that is easiest to understand.

All three of these mistakes have been made in Kubernetes code, getting past code review at least once each that I know of.

1. Loop variables are scoped outside the loop.

What do these lines do? Make predictions and then scroll down.

func print(pi *int) { fmt.Println(*pi) }

#include <stdlib.h>
#define SIZE 1024
static int (**hnew())[2] {
    return calloc(sizeof(int**), SIZE);
}
static void hdel(int (**e)[2]) {
    for (int i = 0; i < SIZE; i++) free(e[i]); free(e);
}
static int (**hget(int (**t)[2], int k))[2] {
    for (int h = k & (SIZE - 1); **t && ***t != k; h = ((h + 1) & (SIZE - 1)), t += h);

# This is the complete example of nginx configuration file for ownCloud 5
# This config file configures proper rewrite rules for the new release of ownCloud
# Also, this config file configures nginx to listen on both IPv4 and IPv6 addresses
# If you want it to listen to IPv4 address only, use listen 80; instead of listen [::]:80

# First, we configure redirection to HTTPS (substitue owncloud.example.com with the proper address of your OC instance)

server {
  listen [::]:80;
  server_name owncloud.example.com;

minteye is a captcha system where you try to find the original image out of distorted ones. They also have a feature list on their website but they forgot the view from a computer. I fixed it:

There are two ways to crack this captcha easily. I've used the audio challange. There are three different kind of audio messages.

1. move the slider to the right
2. move the slider to the left
3. slider is in the correct position
