Speed testing node's default console.log, versus an async logger, versus no logging.

Tested with the looping going up to n <= 65

node-simplelogger: 12.2s (with slight delay after it finished printing before the process ended)
no logging: 10.6s
console.log: 12.8s

These measurements came from adjust line 33 of this file: https://github.com/dsernst/ProjectEuler/blob/67a9c17f0810ff6a5da5c20c027e8c11c7a0c304/53%20Combinatoric%20selections.js#L33

The point of these tests were to see if using an asyncronous logger would be faster than node's built in console. In this case, it did not make a meaningful difference.

How to use distinct npm packages across a host & VM when using a shared project folder

How to use distinctly compiled npm packages across a host machine & VM with a shared project folder

Use bcrypt and mongoose in each, with their own, OS-specific bindings

  1. Go to your ~/ home directory on the machine you want to install OS-specific module for, then run $ npm i compiled-package

  2. Move your package into ~/.node_modules folder (this is a special folder node knows to look in when requireing modules)

  • So probably: $ mv ~/node_modules/compiled-package ~/.node_modules/compiled-package
    • Shorthand: $ mv ~/{,.}node_modules/compiled-package
  • (consider rm -rfing the first node_modules folder to clean up after yourself)

getSpreadsheetData() utility function takes the name of a worksheet, then grabs all the data on the page and gives you back an array of objects, with the first row as property names.
function getSpreadsheetData(sheetName) {
// This function gives you an array of objects modeling a worksheet's tabular data, where the first items — column headers — become the property names.
var arrayOfArrays = SpreadsheetApp.getActiveSpreadsheet().getSheetByName(sheetName || 'Sheet1').getDataRange().getValues();
var headers = arrayOfArrays.shift();
return arrayOfArrays.map(function (row) {
return row.reduce(function (memo, value, index) {
if (value) {
memo[headers[index]] = value;
}
return memo;
