Go / C++ bindings example

This is an example of Go code calling to a C++ library with a C wrapper.

Build

go build  # this only ensures it compiles

radekg

package main

import (

	"crypto/x509"
	"crypto/x509/pkix"
	"encoding/pem"

# This is a unix wrapper around the erlang vm. It provides the following functionality:
#
# * Spawns in foreground
# * Handle SIGHUP and call RELOADFUNC
# * Handle SIGTERM SIGQUIT and SIGINT telling to the vm to quit
# * Dies if the vm dies (for example kernel killing because out of memory)
#
# Forks and improvements are welcome.

a.k.a. what to do when your ISP starts blocking sites :(

Set the SOCKS proxy to local SSH tunnel

networksetup -setsocksfirewallproxy "Ethernet" localhost 8080

To clear the domain and port
