You might have read the infamous blog posts titled “Rails is Dead”, but I have seen development teams flounder over and over again when they try and reinvent the wheel using NodeJS on the backend. Rails is Scalable Despite the negative press, I’ll argue rails does scale. After developers at Twitter have spoken at length about their issues with Rails performance, it’s easy to get the wrong idea. Rails is not the fastest framework in the world… but I will argue that performance is the last thing you should worry about when you want to scale. more»

The “greenfield” project is known by developers as a productivity Nirvana. It is a beautiful place where there is no legacy, no bugs and endless possibilities. It is also littered with mines. I’ve recently seen a number of anti-patterns around the creation and early growth new projects, and thought I’d summarize the anti-patterns I’d seen in the past as a guide for developers to avoid these common pitfalls. 1. Get a Pipeline in Place Early Run your tests automatically. more»

In this live-coding session I work on an Elixir server built to support huge numbers of users chatting in 3d.

Then she gets up and leaves. The patient is still on dialysis, still bleeding in places, and their internal organs are still on show for everyone else in the room. The patient’s immediate future is secure, but eventually they are still going to bleed to death. As a DevOps engineer, perhaps one of the best things you can do for an engineering team is to empower them to write and utilize tests. more»

Until you have found product-market fit, your production environment is often just another test environment. It’s not testing your code, it’s testing your customers. At a previous startup company, we had a few hundred thousand users. Not all that many, but enough to get some interesting data and be in a position to use it to optimize the business. We had previously built a recommendation engine in Elasticsearch which all our users were piped through, and we user it to provide daily recommendations based on our most recent data. more»

ActiveHash is a simple base class that allows you to use a ruby hash as a readonly datasource for an ActiveRecord-like model.

ActiveHash assumes that every hash has an :id key, which is what you would probably store in a database. This allows you to seamlessly upgrade from ActiveHash objects to full ActiveRecord objects without having to change any code in your app, or any foreign keys in your database.

It also allows you to use #has_many and #belongs_to (via belongs_to_active_hash) in your AR objects.

ActiveHash can also be useful to create simple test classes that run without a database - ideal for testing plugins or gems that rely on simple AR behavior, but don’t want to deal with databases or migrations for the spec suite.
