You got your hands on some data that was leaked from a social network and you want to help the poor people.

Luckily you know a government service to automatically block a list of credit cards.

The service is a little old school though and you have to upload a CSV file in the exact format. The upload fails if the CSV file contains invalid data.

The CSV files should have two columns, Name and Credit Card. Also, it must be named after the following pattern:

YYYYMMDD.csv.

# Check box that always submits a value, even if unchecked. This uses the same
# trick as Rails's `f.check_box`: a hidden input with the same name as the
# checkbox but with a value of 0 that appears before the actual checkbox. When
# the checkbox is checked, the checkbox's value will be submitted, when it's
# unchecked, then the hidden input value of 0 will be submitted.

Better local require() paths for Node.js

Problem

When the directory structure of your Node.js application (not library!) has some depth, you end up with a lot of annoying relative paths in your require calls like:

const Article = require('../../../../app/models/article');

Those suck for maintenance and they're ugly.

Possible solutions

var app = require(process.cwd() + '/app');
var winston = require('winston');
var _ = require('lodash');

// Set up logger
var customColors = {
  trace: 'white',
  debug: 'green',
  info: 'green',
  warn: 'yellow',
