I recently came across a function declaration with a Javascript syntax that I had never seen before.

!function() {
  // some logic
}

This ! bang is called the unary operator.

I immediately started playing around in the Node console to try and understand this syntax.

Here's a quick helpful template that we've refined through our work at Boombotix and OneLogin: a short pull-request template that can be used to inform team members of the status and scope of a particular feature branch.

In a recent set of Rails services I built, my team wanted to quickly deploy to Heroku for testing. We also keep a YARD documentation server running and up to date for every deploy.

Turn out there is not a simple way to do this on Heroku, as you can only run one public-facing HTTP server per application.

Update!

Read this first, and if you want more I've posted an update to this blog here.

Backstory

My roommate works for Apple, and travels to China for work. He brought back a spool of LED lights, and hacked together a script for an Arduino that played a series of 12 lights on repeat.

Recently at OneLogin we decided to prune and purge all merged branches in one of our large Git repos. Having never had to do this with more then a handful of branches, I had relied on the GitHub branches UI.

This UI is less than ideal when working with over about a dozen branches, so I started looking into scripts to help automate the process.
