json schema

To use a local json schema inside your project with Visual Studio Code create a .vscode folder and a settings.json file inside it. Then set the following configuration tuned up for your specific needs:

• fileMatch will match any file with that naming pattern;
• url will start looking from the root folder of your project. Read more about it (here)[https://code.visualstudio.com/docs/languages/json#_mapping-to-a-schema-in-the-workspace].

# Inside the "repos.txt" file, set the repositories names, one per line.
# The target folder is always generated in the current directory where the script is executed.
# Inside the new folder, each repository will be stored inside a tar.gz archive.
# Each repository is cloned as a mirror, so you can push it to a new remote.

package.json

engines

It's good practice to set the required node and npm version for your project. To do so add to the package.json:

"engines": {
  "npm": ">=9.0.0 <10.0.0",
  "node": ">=18.0.0 <19.0.0"
}

This is mostly for my own benefit when I invariably format a computer using these adapters and forget how to get wifi working again:

• TP-Link T2U Nano (AC600)¹
• TP-Link T3U Plus (AC1300)¹

Plug device in and ensure it is detected via lsusb:

For the T3U Plus, the ID is 2357:0138.

linux-ssh preliminary setup

Nothing (usually).

macos-ssh preliminary setup

macOS won't automatically add our keys (especially if protected by a passphrase) to the ssh agent. In order to fix this, we will open Automator and create a new shell script: Automator > Application > Run Shell Script. The content is the following:

# add all keys inside "~/.ssh" into the ssh-agent and discard the output
ssh-add -A 2> /dev/null
