I’m a maintainer and big fan of Docker Machine for quickly generating and using Docker hosts in the cloud and elsewhere. Creating and accessing machines, however, is only the beginning of the battle, as most drivers will leave you with a machine which is a relatively blank slate, and you may want to customize the machines to your liking with a provisioning process of your own in addition to Docker

The Nate Shells Out In a perfect world we would have beautifully designed APIs and bindings for everything that we could possibly desire and that includes things which we might want to invoke the shell to do (e.g. run imagemagick commands, invoke git, invoke docker etc.). But especially with burgeoning languages such as Go, it’s not as likely that such a module exists (or that it’s easy to use, ro

What? People from all sorts of backgrounds are flocking to the Go Programming Language and even for those who have written C and C++ before (myself included) it may be confusing to grok Go’s approach to pointers, and how they interact with the methods you can attach to Go’s structs. In Go, you define a method receiver to specify which struct to attach a certain function to in order to make it invo

Say that title five times fast! Seriously though, I wasn’t sure what else to call this article so that people would actually find it. This article is a spiritual successor to Evan Hazlett’s article on running the ELK stack in Docker and ClusterHQ’s article on doing it with Fig/Docker Compose and Flocker. Huge shout out to them for being the giants whose shoulders I stand on. It is also influenced

EDIT: As pointed out by effenn in this Reddit comment, a lot of information in this article is “dangerously inaccurate”. OOPS! I’ve written a followup/correction article here for your viewing pleasure, but I’m leaving this article up for “historical purposes”. Goroutines and channels are one of Go’s nicest language features. They provide a rather headache-free way to use the power of concurrency i

Unfortunately, I haven’t been writing as much as I’d like to lately. Partially this is because I’ve been quite busy with Docker-related things, but it also has a lot to do with aspects of my blogging stack (and approach) that were beginning to show their weaknesses. The way that this blog got started was as an Octopress installation on a Macbook Air. I loved the Octopress default theme’s clean des

EDIT: Some commenters were confused about some things in this article, and I don’t want people to get an unclear picture, so to clarify: Yes, I know that insertion into a hash table creates an arbitrary ordering of elements by definition. For a variety of reasons, e.g. that not every map is a hash map as some posters have pointed out (and some languages have ordered hash maps), I can see how someo

Anyone who follows my blog even a little closely can probably see that I <3 AngularJS: How to Unit Test Controllers In AngularJS Without Setting Your Hair On Fire Don’t Fear Directives In AngularJS Fear and Loathing With Golang and AngularJS As I’ve learned more about the framework, I’ve come to appreciate many of the design decisions in spite of their initial (beastly) learning curve. For example

Developers almost universally agree that unit tests are a VERY GOOD THING when working on a project. They help you feel like your code is airtight, ensure reliability in production, and let you refactor with confidence when there is a need to do so. AngularJS code touts its high degree of testability, which is a reasonable claim. In much of the documentation end to end tests are provided with the

Server Side JavaScript As many of you are probably aware, Node.js is all the rage with the kids these days. It’s so popular that users even have the nerve to gall Google developers, insisting that the V8 JavaScript engine is important for things outside of mere Chrome. Node has rapidly been evolving and maturing into the new hotness of the web development community. Its core is driven by the idea
