# This is a Python script to regress an ellipse from a list of (x, y) coordinate pairs
# it heuristically optimises the coefficients of the following equation:
# Ax^2 + Bxy + Cy^2 + Dx + Ey + F = 0
# It tries to minimise the MSE between observed points and points predicted by the model

# Method:
# It may not be the most optimal method but it's reasonably fast, was quick to implement and works
# - Randomly picks 5 points out of the list of points
# - Solves for the coefficients by solving the corresponding system of equations
# - The solution is evaluated by randomly selecting coordinate pairs and evaluating their MSE

Listening for m3u8 files using TShark

Set-Up

In order to capture https traffic, some setting up is required in order to allow tshark to decrypt the traffic.
A pre-master secret key will be used in order to do this.

Basically, we need to get the browser to log a SSL key log file. This can be done by following the steps here: https://www.comparitech.com/net-admin/decrypt-ssl-with-wireshark/.

In summary, the steps are:

1. export SSLKEYLOGFILE=~/.ssl-key.log
