In the solution for the pastebin/bitly system design, the write to cache flow is missing in the second diagram which refers to the scaling aspect. The cache has only a read arrow but not a write arrow. The diagram will be more intuitive if a write-through/write-back cache mechanism was indicated.

Was somebody able to make this thing work with react and functional components? Would be great if somebody could share some ideas.

In overall I've enjoyed ZeroNet very much. However, when I've reached "How can I create a ZeroNet site" section I've found non-obvious that instead of using zeronet.py as a Windows user I could use zeronet.cmd from \lib folder. Since I've found pip package manager UX quite frustrating I think that this is a thing that should

While reading the wifi doc , I see

You need to install the wireless-tools package on your system.

The manpage doesn't give information as to what is really used behind, all I can find is:

   W      Show/hide Wifi module

And the WiFi plugin doesn't show up in my glances terminal view.
Unfortunately,

This isn't as much a bug as it is a question/suggestion.
Button material setup and ripple code needs updating.

Should the [Getting Started Guide][1] linked as the first link of the README Important Links be a part of automated testing and quality control to ensure that this 'seemingly simple' first introduction to material-components-web will yield the results that are intended?

I ask

Please add documentation about what value should TERM contain, and where to set it (in the gotty session from the browser, or from CLI before running gotty?).

I noticed an undocumented behavior with listeners, where some of them run in reverse order of registration

1. What is the rationale for that?
2. Can this be added to the docs?

Hi! I'm creating this issue to list Aurelia features that are not documented yet.

I can make the PR's to update the docs, but I want to be sure that I'm right before doing anything. So please, tell me if these changes are welcome.

Is there an overview, how the config object for the constructors of the neural network are defined?

This would be interesting:

• Has brain.NeuralNetwork and brain.recurrent.RNN the same config attributes?
• What is the description of the inputSize attribute?

Thank you for the great work with this library, it is realy amazing!

A real easy change here.
Because Class::push was made to check if a class string was empty (here), there are a couple of unneeded checks in VTag that do the same thing ([here](https://github.com/yewstac

I think it's unexpected. I have to use Detector.canCollide on my own when I want to use Query.collides. I think it should be changed or at least mention in documentation.

Using Debian 9 via WSL (Windows Subsystem for Linux).

As anticipated, install steps 1 & 2 gave no issues. Realised needed to sudo for :80, as documented by you.

All widgets are populated and it's running nice and smoothly.

Is this now Linux Dash on Windows? 😆

Should we consider add example to each topics?
How to use it and best practice to use it!

I.e: for helloworld demo the example would be http://localhost:8080/demo/hello?who=ibrahim

Thanks for the fantastic library!

I have been reading through documentation and examples to learn about Rocket. One thing that confused me is the use of macro_use, extern crate, and serde_derive, none of which I believe are necessary any more (or at least they do not appear to be in my testing). For example, the tera_template example currently begins with:

#[macro_use] extern
