### Caching of static resources
Caching is a technique in which some of the site's resources, such as style sheets and images, are provided with additional headers thta tell the visitor's browser to save a local copy of those files. This ensures that the next time they visit the same page, the files are loaded from the local cache rather than being transmitted over the network again. This not only reduces the time to load the entire page, but also lowers resource usage both on the network and on our server.

The common practice is to cache everything except the HTML, so that when the user loads the web page again the HTML will notify the browser of all the changes. However since lowtechmagezine.com publishes only 12 articles per year, we decided to also cache HTML. The cache is set for one day, meaning it is only after a week that the user's browser will automatically check for new content. Only for the front and about pages this behaviour is disabled.

:::console
sudo certbot certonly --authenticator webroot --pre-hook "nginx -s stop" --post-hook "nginx"
Use the `certonly` directive so it just creates the certificates but doesn't touch muh config.
Use the `certonly` directive so it just creates the certificates but doesn't touch much config.
This will prompt an interactive screen where you set the (sub)domain(s) you're requesting certificates for. In our case that was `solar.lowtechmagazine.com`.

### Server
The server itself is an [Olimex Olinuxino A20 Lime 2](https://www.olimex.com/Products/OLinuXino/A20/A20-OLinuXino-LIME2/) single board computer.
We chose it because of the quality of the (open source) hardware[^manual], the low power consumption and useful extra compnents such as the charging circuit based on the [AXP209 power managment chip](http://dl.linux-sunxi.org/AXP/AXP209_Datasheet_v1.0en.pdf).
We chose it because of the quality of the (open source) hardware[^manual], the low power consumption and useful extra components such as the charging circuit based on the [AXP209 power managment chip](http://dl.linux-sunxi.org/AXP/AXP209_Datasheet_v1.0en.pdf).
This chip makes it possible to query power statistics such as current voltage and amperage both from the DC-barrel jack connection and the battery. The maintainers of [Armbian](https://www.armbian.com/olimex-lime-2/) exposed these statistics via `sysfs` bindings in their OS.
