Writing quality Git commits has been written about to death, but it is so important that I could not help myself from sharing my thoughts on the subject. Mostly, I will be rehashing what Tim Pope has shared, but I will also include a few of the things that I have used to improve my source histories.

Limit the subject of your commit to 50 characters

Many people live life as I do: at the command line. Limiting to 50 characters allows room for us to use an 80 character width for commands such as git rebase --interactive without width concerns. …

One of my primary motivations for working with Docker was creating a single artifact that I could toss into any environment. It has been fantastic at this. I can throw together a simple Dockerfile that will build my Rails application as an image for production in about five minutes.

Except now that when I need to run the application’s test suite, I do not have the dependencies I need. That Dockerfile might look something like this.

Many people decide to include both of these Dockerfiles in their repository as Dockerfile and Dockerfile.dev. This works perfectly fine. But now…
