Intro

I've noted that there have been a lot of books in the recent past that were judged interesting, and heard wishes for them being suggested again. So, this time my new suggestions are kept at a minimum, to give us a chance of selecting something that was reluctantly passed over previously.

New suggestions

Tim Gregory - Going Nuclear: How the Atom Will Save the World (2025) {384pp} [Goodreads link]

Was it Rosling that pointed out that energy consumption and prosperity seems to go hand in hand, and that the former is required for the latter? I do not remember. This seems to be an interesting book in which the author urges us to rethink the path to net zero. He argues that the solution to climate change lies not simply in replacing fossil fuels with renewables, but in fully embracing another energy source that emits zero carbon dioxide: nuclear power. Gregory dismantles the conventional wisdom that renewables such as wind and solar are completely ‘gree

Functions for getting process lists and process trees of podman containers from the host's perspective
function pdmn-ps() {
# With this one can do like, given a container called tor-client,
# kill -HUP $(pdmn-ps tor-client | \
# grep -F ' tor -f /config/torrc --defaults-torrc /config/torrc.custom.default' | \

# Useful for when one has both a client and a relay, and has a smaller overhead than exec-ing into the container.

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'
