DSCF4286 Last week at RailsConf in Kansas City, Terence Lee and Richard Schneeman of Heroku’s Ruby Task Force sat down with the legendary Aaron Patterson (AKA tenderlove).

Aaron has been working hard to make Ruby three times faster — a goal that Matz called Ruby 3x3. Along the way, Aaron has discovered that Ruby may face a hard decision. On one side, Ruby can continue to be the productive, general-purpose scripting language that it looks like today. But the other side of Ruby is that it’s used to run long-running processes in Rails applications, pushing it to be more performant, strongly-typed, and memory-heavy. Ruby can't prioritize both.

To find out where Aaron thinks Ruby’s going, you can...

It's been one year since Action Cable debuted at RailsConf 2015, and Sophie DeBenedetto is here to answer the question in the minds of many developers: what is it really like to implement "the highlight of Rails 5"? Sophie is a web developer and an instructor at the Flatiron School. Her first love is Ruby on Rails, although she has developed projects with and written about Rails, Ember and Phoenix.


Recent years have seen the rise of "the real-time web." Web apps we use every day rely on real-time features—the sort of features that let you see new posts magically appearing at the top of your feeds without having to lift a finger.

While we may take those features...

Rails 5 will be the easiest release ever to get running on Heroku. You can get it going in just five lines:

$ rails new myapp -d postgresql $ cd myapp $ git init . ; git add . ; git commit -m first $ heroku create $ git push heroku master 

These five lines (and a view or two) are all you need to get a Rails 5 app working on Heroku — there are no special gems you need to install, or flags you must toggle. Let's take a peek under the hood, and explore the interfaces baked right into Rails 5 that make it easy to deploy your app on any modern container-based platform.

Production Web Server as the Default

Before Rails 5, the default web server that you get when you run $ rails server is...

We recently sat down for a chat with Bill Curtis, a co-founder and the CTO of Sweet Tooth, a points and rewards app for online stores worldwide.

What has been your greatest challenge?

We’re serving way more data today than we ever have, so scaling is mission-critical. In the past, we’ve struggled with traffic spikes. For example, there are seasonal spikes, like Black Friday or Cyber Monday. There are also spikes from merchant activity, such as load testing stores or importing a large number of orders.

I recently tweeted our requests-per-hour graph. It showed that during the huge spikes for this year’s Black Friday and Cyber Monday, our product availability was seamless on Heroku. That...

Based in Tel Aviv, Israel, Vitali Margolin is the Head of R&D for Roomer. Vitali leads a team of seven developers who built and operate the travel marketplace www.roomertravel.com and the travel protection service www.life-happens.com, both running on Heroku.

What are you running on Heroku?

The four big projects are: the Roomer website, our administration app, our partner network and B2B website, and the Roomer API. The Roomer API is our highest load app. It can get up to 10k requests per minute from partner integrations such as Kayak. We have a few more technical products, including an app that does text recognition and automatically decodes confirmation emails, as well as a smart...
