Non-fiction titles for Lund (Audio)Book Club Meetup Group 20250423

A lot of book suggestions this time, and so surely some will be recycled in the future while others might be read outside the scope of this book club. :)

On the topic of game theory

I for one have been in search for a good pop-sci book on game theory. But, they are not easy to find. Maybe because it is difficult to make something that is both easy enough to read and still useful. The topic is increasingly interesting with the collapse of trust in media, leaving one left to one's own devices for building a sensible picture of where things are heading. Although truth be told, game theory has been a good tool to understand stuff for some time. Did you for instance know that the banning of cigarette ads in the US actually lead to increased profits for the dominating companies, and that this was no unforseen side effect? Understanding simple games, like The prisoner's dilemma and it's societal version The tragedy of the commons may shed new light on why collaborating towards outcomes that are better for all inv

Fix of WireGuard routing confusion on OpenWRT
#!/bin/sh
# Intermittently, the routing of WireGuard datagrams seem to become confused, leading to temporarily hung connections.
# This script aims to remedy this - assuming that the OpenWRT system is a
# WireGuard peer that uses the port(s) listed in WG_PORTS. E.g. (/etc/config/network):
# config interface 'wg0'
# option proto 'wireguard'
# option listen_port '51820'
