Once you've worked with Docker for a while, you have probably noticed that it eats disk space like a whale. And when that disk space runs out, everything on your server usually grinds to a halt.
Let's get it right from the start: Containers can take you to horrible, horrible places.
But they are also awesome. They make shipping and deploying your application much easier.
This post is your survival guide to the editor Vim.
In this post I'll show you how to expose a locally running development server on the Internet. This is something I use often to run external tests against an app I'm building with Python and Flask.
I got tired of existing dynamic DNS services, so I built my own - with a twist. Me and at least 3 of my friends think it's cool.
Working with cellular data, I used to have problems with hanging SSH sessions for a decade. That is, until a friend of mine introduced me to mosh.
Having DevOps as a separate function within an organisation has its caveats. Consider a traditional problem, a driving force behind the DevOps movement: Developers do not know where their code is running, or how it gets there. System administrators do not know how the code they are running works.
Terraform is a great tool for building infrastructure in the cloud. Ansible is a beautifully simple agentless (and serverless) configuration management tool. A common use case is to build servers with Terraform, and have Ansible configure them. Unfortunately Terraform lacks a provisioning plugin for Ansible - but fear not, they can be used together fairly trivially by using the local-exec provisioner of Terraform.

In large organisations using the public cloud to store code, it's unfortunately not uncommon to accidentally make something public that should be private. Whether that's due to negligence or ignorance, a leak can have dramatic consequences.
