Node.js

Q1: What do you mean by Asynchronous API? ☆☆

Answer: All APIs of Node.js library are aynchronous that is non-blocking. It essentially means a Node.js based server never waits for a API to return data. Server moves to next API after calling it and a notification mechanism of Events of Node.js helps server to get response from the previous API call.

For some reason, it is surprisingly hard to create a bootable Windows USB using macOS. These are my steps for doing so, which have worked for me in macOS Monterey (12.6.1) for Windows 10 and 11. After following these steps, you should have a bootable Windows USB drive.

1. Download a Windows disc image (i.e. ISO file)

You can download Windows 10 or Windows 11 directly from Microsoft.

2. Identify your USB drive

After plugging the drive to your machine, identify the name of the USB device using diskutil list, which should return an output like the one below. In my case, the correct disk name is disk2.

Direct Audit

This recipe is for advanced usages of Lighthouse as a Node library.

Normally, Lighthouse runs Chrome and generates a set of artifacts to use as input to many core modules (such as audits or computed artifacts). You can use these modules directly, but you must provide the inputs yourself.

Inertia.js ships with a fantastic form helper but it falls short when also using API/Axios calls in your project.

Here's a composable, built on top of the Inertia's form helper that hooks into it to replace the API calls with Axios.

To use, just replace useForm with useAPIForm.

const form = useAPIForm({
    title: '',
});

Run RISC-V Debian GNU/Linux bullseye/sid via QEMU.

Run the latest version of Debian on regular x86_64 box (at least ver 10 Buster, better to run ver 11 Bullseye)
If opensbi and u-boot-qemu packages are not found add testing apt repository (aka bullseye). Or even unstable (aka sid)

sudo vi /etc/apt/sources.list

# Add testing repo (or unstable)
deb http://cdn-aws.deb.debian.org/debian testing main
deb-src http://cdn-aws.deb.debian.org/debian testing main

Cheat Sheets are greate but they are not a substitute for learning the framework and reading the documentation as we most certainly have not covered every potential example here. Please refer to the Rails Command Line Docs for more information.

Command Line Generator Info

Reference

You can get all of this information on the command line.

rails generate with no generator name will output a list of all available generators and some information about global options. rails generate GENERATOR --help will list the options that can be passed to the specified generator.
