This runs a build for a small elixir (phoenix) project in about 40 seconds by caching as much of the compiled files as possible.

We've been using this for months in multiple projects without any issues. Please ping be if there is any issues with this script and I'll update it.

It should be generic enough to work on any elixir app using mix.

If you have a elixir_buildpack.config, then enable that section in the build script to keep versions in sync!

2016-08-09: Updated to newer Erlang and Elixir and fixed curl command.

PSQL

Magic words:

psql -U postgres

Some interesting flags (to see all, use -h or --help depending on your psql version):

• -E: will describe the underlaying queries of the \ commands (cool for learning!)
• -l: psql will list all databases and then exit (useful if the user you connect with doesn't has a default database, like at AWS RDS)

Sending emails from Gmail Using Golang

Sending emails from a Gmail account using Go can be done using Go's smtp package. Simply:

1. Connect to smtp.gmail.com on port 587, authenticating using your email and password
2. Optionally, use Go's text/template package to format the To, From, Subject, and Body fields of your email
3. Use smtp's SendMail method to actually send the email

An example usage follows. The SmtpTemplateData struct is used to hold the context for the templating mentioned in (2) above.

CoffeeScript 1.7 is shaping up to be a pretty kick-ass release with significant improvements. Here are the ones I'm most excited about, in order of my own excitement.
