There are data centers of various sizes, core networks, last mile networks & user devices. Data centers have high variablity in energy consumption, networks have intermediate differences, "last mile" can have big impact in corporate environments and user devices have high variablity in resource consumption. Energy consumption in switching from consumers to networks and DC's and AI is the new big dog for energy consumption.

There are different types of energy and electricity consumption will double in 10 years.

Modern datacenters consume a substantial amount of power & cooling.

We consume a lot more than what we used to. Processing power has gotten cheaper and more abundand. We also use a lot of network resources. Both of these things lead to a lot more co2 and energy usage. Even renewable energy sources aren't something that we should use without consideration since they do produce lifecycle emissions. People have different first thoughts of what are the elements of SusIct. We should take a holistic view when we're looking into the topic, since ICT-companies like to emphatize the good effect of ICT (eg. the handprint). Video is growing at a staggering rate and the Western world might have already peaked in network usage. AI is another growth driver. The course is mostly about sustainability of energy usage.

Is it too late to get in on the action? I think not.

Rsync is handy. It makes publishing a breeze when combined with Makefile.

Some things, ie. restarting services on server can be done easily, by editing visudo-file and thus removing sudo-pwd requirements for certain action.

Lets learn FastHTML. It's been branded as a quick and nice way to get a site running.

WireGuard Easy, or wg-easy, is a convenient way to do wireguard setup on your local & remote machine. It makes vpn-setup a breeze.
