VS Code utilizes too much RAM when coding in python

see issue of the "Microsoft/python-language-server" "High memory usage #832" Since the problem is not fixed, the only suggestion is: set

"python.jediEnabled": true

to use Jedi instead of Microsoft Python Analysis Engine.

test network environment script in xdp-turorial

Test environment script

This directory contains a setup script that you can use to create test environments for testing your XDP programs. It works by creating virtual ethernet (veth) interface pairs and moving one end of each pair to another network namespace. You can load the XDP program in the other namespace and send traffic to it through the interface that is visible in the root namespace.

Tcpdump

Tcpdump is a commandline tool that is used to dump traffic on a network. This tool comes in hand when you want to analyse network captures within the command line. Basically it can do most of the wireshark job.

NOTE This guide might not be complete it just serve as a reference to me.
