HPR4143: Learning to touch-type using the Dvorak keyboard layout
After 40 years of 'hunt and peck' typing I finally bit the bullet and learned to touch type, using the Dvorak keyboard layout.
I found plenty of online tools and listings of software designed to help, and I cover some of these in this episode.

HPR4142: A Shared Shell History With Atuin
In this episode Marcus / mnw walks you through the install and
initial configuration of a shell history replacement called Atuin.
My first show I'm quite nervous!
Config Options
These are the settings suggested to change in the config file
~/.config/atuin/config.toml
auto_sync = true
style = "compact"
inline_height = 10
enter_accept = false
Trouble Shooting
Is my postgresql working ?
psql -d "postgres://atuin:ak4hTNms5Y@127.0.0.1:5432/atuin" -c "select now()"
Is my service running?
service atuin status
Syncing
On the first host you register on you want to grab your key.
atuin key
Then login and use that key on the other clients with
atuin login -u username -k "the word soup from the atuin key command"

HPR4140: Battery and Charging Technology 2024
It is obvious to most people that we need to stop burning fossil
fuels to prevent even worse global climate change. Options like solar
panels and windmills are options for providing clean renewable
electricity, but since so much of our fossil fuel use is for
transportation, we need to make strides in improving batteries and
charging. Fortunately there have been some very positive developments
that will show up within just a few years
