node and npm: run brew install node npm

Download the script
Give permissions to run chmod +x install_ssl.sh

Example:

Assert.true(true,'This is truthful');
Assert.true(false,'This is truthful');
Assert.false(false,'This is a lie');
Assert.false(true,'This is a lie');
Assert.equals(typeof 'hola', 'string', 'This variable contains a message');
Assert.equals(typeof 3, 'string', 'This variable contains a message');

Result:

Cached Runner

Receives a period of time and a request function, and performs all async operations to get the data. If you retry the request in a time shorter than the period it returns the cached result instead.

You can also set a postprocess function and another function that runs every time.

Simple example

Usage

const simpleCahedRun = new CachedRun(2500, ()=&gt;Math.random());

PURPOSE

It's not trivial to deploy a cron scheduler on Google Cloud. Here I purpose a simple way to prototype it. Since most part of tasks will only need a basic frequency trigger the hourly / daily / weekly / monthly percision will suffice.

1. Create the Appscript on Google Drive

Just drop the appscript.gs code insdie a freshly created appscript project. Name the project with an easily recognizable name since Google Drive doesn't let you filter by appscript file type.

	// libs
	const request = require('request');
	const {RateLimiter} = require('limiter');

	// config
	const pool = {maxSockets: 100};
	const url = 'http://google.com';
	const numRequests = 10000;
	const requestLimit = 5000;
	const limiter = new RateLimiter(requestLimit, 'hour');

	function primes(max) {
	let calculated = [1, 2, 3]; // already calculated primes
	let num = 4; // current number being checked
	let factors; // factors for the given number
	let sqrt; // sqrt for a given number
	// if the input is too low to be calculated, just return the default primes
	if (max < 5) return calculated;
	// otherwhise calculate for each number till you reach max
	while (num < max) {
	// discard even numbers

	#!/usr/bin/python

	# This little script creates users in an airflow instance so it can be open to the public.
	# It gets the password in plain text so be careful where you run it.
	# You can properly invoke the script as follows:
	# ./add_user.py <username> <[email protected]> <secretpassword>

	import airflow, sys
	from airflow import models, settings
	from airflow.contrib.auth.backends.password_auth import PasswordUser

	if(document.referrer){
	var url = new URL(document.referrer)
	console.log("Check refferer and redirect: " + document.referrer);
	if(url.pathname === '/customer/account/create/'){
	console.log("Redirecting to post-register form");
	window.location.href = '/post_register';
	}
	}

	function searchAndInsert(node, trigger, name) {
	var results = [];
	if (node == {})
	return false;
	for (child in node) {
	for (t of trigger) {
	console.log('child', child, 'trigger', t);
	if (child == t && !child[name]) {
	//console.log('node', node, 'child(trigger)', node[child],'name', child[name])
	node[child][name] = {};

	#!/usr/bin/env Rscript
	args = commandArgs(trailingOnly=TRUE)

	base_file <- paste0(getwd(),'/',args[1])
	delta_file <- paste0(getwd(),'/',args[2])
	altas_file <- paste0(getwd(),'/',args[3])
	bajas_file <- paste0(getwd(),'/',args[4])

	cat('cargando base... \n');
	base <- read.csv(base_file,sep=',',header=FALSE)
