J-Cake / Multi instance comms.js
Created January 16, 2019 13:01
How to only have one instance of a window open while feeding info into it.
let isMainWindow = false; // keep track of main instance.
// Of course the main instance should be kept track of in a better way than this, perhaps find a way of uniquely identifying the tabs
// and storing the ID of the active tab in localStorage.
window.addEventListener('load', e => {
if (!window.localStorage.mainWindowVacant) window.localStorage.mainWindowVacant = "true"; // initialsise window.localStorage
if (!window.localStorage.openInstances) window.localStorage.mainWindowVacant = "true"; // initialsise window.localStorage
if (window.localStorage.mainWindowVacant !== "false") {

J-Cake / NN.js
Created February 15, 2019 07:05
Malfunctioning NN. I gave it my best shot at translating from python.
let weights = Array.from({
length: 3
}, () => Math.random() * 2 - 1)
// let weights = [-0.16595599, 0.44064899, -0.99977125]
let inputs = [
[0, 1, 1],
[1, 1, 1],
[1, 0, 1],
[0, 1, 1]

A simplified demonstration of what I'm trying to achieve in C++
#include <store.h>
#include <iostream>
int main() {
cout << Store.name << endl;
Store.name = "Isaac";
cout << Store.name << endl;
}

J-Cake / Track Download Progress in node.js
Created July 9, 2019 13:14
This script records progress made over download without using the `pipe` function and is incredibly memory efficient.
const http = require('http');
const fs = require('fs');
const path = require('path');
const fileLocation = path.join(__dirname, 'video.mp4');
fs.writeFileSync(fileLocation, '');
const file = fs.createWriteStream(fileLocation);
function printSize(bytes) {
