Find n-th pair of prime numbers with a difference of two in MATLAB
n = 90;
disp(primePair(n))
function p = primePair(n)
% Incredibly inefficient, use the primes vector instead.
% I just came up with this during an exam and didn't want
% to think about going over the vector correctly too much.
a = [ -2 0 ];
counter = 0;

# I know this is dirty, but come on, starting my Windows virtual machine
# just freezes everything and the whole thing won't even respond to `systemctl`.

# Use with root privileges, not my responsibility if you mess things up.

Expose a SOCKS proxy in a virtual machine that routes traffic through another VPN connection

Instructions

  • Install Debian (or your distro of choice) in a virtual machine.
  • Configure OpenVPN/Wireguard.
  • Install dante-server and paste the contents of danted.conf in /etc/danted.conf.
  • Make the appropriate changes to the aforementioned configuration file.
  • Run ip a and take note of the IP address of the virtual machine.
  • Run sudo systemctl enable --now danted.
  • Ensure that the proxy is functioning properly with sudo systemctl status danted.
  • If all went well, you should now be able to connect to your SOCKS5 proxy!
