The following is capturing instructions on how to add custom naming for an Arduino Leonardo (or generic pro-micro) for my Arcade Controller device. I wanted to have a simple record so that when I inevitably come back to this someday I can recall how I accomplished this. Reference was taken from the following YouTube video (https://youtu.be/hoCOq9Ngp44?t=1156) at approximately 19m16s.

WINDOWS Instructions:

Create a new set of folders: ~\Documents\Arduino\hardware\daemonbite\avr

Copy everything from C:\Program Files (x86)\Arduino\hardware\arduino\avr to this new folder.

When attempting to build the awesome serialport NPM package in Docker using a node alpine image, in usually failes on building the node-gyp package.

There are various workarounds which can be found online, such as this one.

However, the key ingredient is building the serialport package from source, using this line:

npm install serialport --build-from-source=serialport

Make Vue events bubble

Vue events don't bubble the component tree on their own. However when writing wrapper components this can be the desired behaviour.

This code registers a global bubble directive which allows to re-emit all given events:

Let's say we want to bubble events start, accelerate and brake of our component Car.

Without any help, we'd roughly have to do this:

Workbox runtime caching recipes

Your Service Worker script will need to import in Workbox and initialize it before calling any of the routes documented in this write-up, similar to the below:

importScripts('workbox-sw.prod.v1.3.0.js');
const workbox = new WorkboxSW();

// Placeholder array populated automatically by workboxBuild.injectManifest()

var fs = require('fs');
var crypto = require('crypto');

fs.readFile('file.pdf', function(err, data) {
  var checksum = generateChecksum(data);
  console.log(checksum);
});

function generateChecksum(str, algorithm, encoding) {
    return crypto

Elapsed and execution time display for commands in ZSH

Append this to your ~/.zshrc file.

function preexec() {
 timer=$(($(date +%s%0N)/1000000))

Not all random values are created equal - for security-related code, you need a specific kind of random value.

A summary of this article, if you don't want to read the entire thing:

• Don't use Math.random(). There are extremely few cases where Math.random() is the right answer. Don't use it, unless you've read this entire article, and determined that it's necessary for your case.
• Don't use crypto.getRandomBytes directly. While it's a CSPRNG, it's easy to bias the result when 'transforming' it, such that the output becomes more predictable.
• If you want to generate random tokens or API keys: Use uuid, specifically the uuid.v4() method. Avoid node-uuid - it's not the same package, and doesn't produce reliably secure random values.
• If you want to generate random numbers in a range: Use random-number-csprng.

You should seriously consider reading the entire article, though - it's

copy/paste to terminal>  inxi -Fxxrzc0 | pastebin # <-- everything from '>' up to '#' is the command, share the link/url output in chat.

1.  you are going to share output from 'inxi' https://github.com/smxi/inxi and
2.  that outupt is going to go to a anymouse pastebin,
3.  the 'pastebin' command sends it to 'gist' aka github pastebin, https://gist.github.com/
4.  you see the link before anyone else, look at it, then share it,
5.  is it safe? the 'z' option forces the mask of 'mac id's' , everything else i would not care who knows.
6.  google does not index an anymouse gist, meaning its not going to haunt you later.
