Squashing Git Commits

The easy and flexible way

This method avoids merge conflicts if you have periodically pulled master into your branch. It also gives you the opportunity to squash into more than 1 commit, or to re-arrange your code into completely different commits (e.g. if you ended up working on three different features but the commits were not consecutive).

Note: You cannot use this method if you intend to open a pull request to merge your feature branch. This method requires committing directly to master.

Switch to the master branch and make sure you are up to date:

Sendy

Sendy is a self hosted email newsletter application that lets you send trackable emails via Amazon Simple Email Service (SES).

Heroku

You can deploy Sendy on Heroku using the following instructions (I assume you've already installed the heroku toolbelt).

  1. On Heroku, create a new app.
  2. Clone that app to your desktop

This example uses Scala. Please see the MLlib documentation for a Java example.
Try running this code in the Spark shell. It may produce different topics each time (since LDA includes some randomization), but it should give topics similar to those listed above.
