Duplex Async Generator

This code demonstrates the how to combine a reading generator and a writing generator together into a duplex generator.

The duplex generator will simultaneously read and write at the same time from both the readable and writable generator.

Throwing an exception throws it to the writable generator, but we continue on (but make sure to skip 1 iteration by using the errored flag).

We use the null value to indicate the ending of the generator, it ends both reading and writing sides.

Edit the Boot Command Line with systemd

If you hit a boot error where there is a start job that cannot be terminated, you can enter the systemd debug shell.

To do this, at the systemd-boot menu, hit the e key and specify: systemd.debug-shell=1.

In the future you can do this in configuration.nix:

systemd.additionalUpstreamSystemUnits = [ "debug-shell.service" ];

Flexbox Sidebar with Overflowing Grid Items

Most flexbox layouts work by using the intrinsic sizing.

This means the sizes of boxes are determined by the size of the contents.

This is usually a good thing because you want your layout to stretch to the content, but also to the available space.

This makes layouts "flexible".
