How to securely set rails secret key when you deploy to Heroku.

Stop Versioning Rails Secret Tokens

After reading Code Climate's Rails' Insecure Defaults I realized I was guilty of breaking rule 3. Versioned Secret Tokens. Here's how I fixed it.

Use dotenv in development and test environments:

# Gemfile
gem 'dotenv-rails', groups: [:development, :test]

How to identify malformed characters or illegal byte sequence in files

Legacy Data

When dealing with legacy data it's been pretty common to run into malformed / illegal byte sequences in files. Figuring out what's causing the issue is often really difficult, especially when the file has thousands of rows.

Here's a trick I pretty much stumpbled upon:

nl file.txt | sort

sort: string comparison failed: Illegal byte sequence
sort: Set LC_ALL='C' to work around the problem.
