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.

[UPDATED FOR #HEARTBLEED]

How to use Heroku's SSL Endpoint with an SSL certificate purchased from GoDaddy.

Heroku's docs on this are now the definitive source. I just followed their instructions to update my apps and they're much better than they were when I made this gist. Here's the previous revision if you need still need it. Good luck!

# PG 96. upgrades the readline to v7, which breaks anything linked against readline v6, like ruby via ruby-build. 
# I *think* this should prevent it from installing v7. But if weird shit happens with various rubies, 
# you'll have to reinstall them.
brew pin readline

# Stop current Postgres server

# As a general rule, I despise all things SEO with it's witchery and voodoo ways.
# However, these two practices are confirmed semi-non-witchcraft SEO best practice.
#
# 1. Serve your content from a consistent domain (www vs. non-www, Doesn't matter. Just be consistent)
#    In addition this is nice for Heroku and other cloud based deployment environments that leave your app 
#    accessible from a url like http://myapp.herokuapp.com
# 
# 2. Believe it or not, trailing slashes matter. The google machine interprets http://domain.com/about 
#     as a different page than domain.com/about/ 
#    (source: http://googlewebmastercentral.blogspot.com/2010/04/to-slash-or-not-to-slash.html )
