Announcing A Very Ruby Thanksgiving

We’re very excited that our Heroku colleagues Matz, Nobu and Ko1 will all be visiting from Japan soon to attend RubyConf, and it’s especially serendipitous that it is happening in such close proximity to Thanksgiving. Not only is Thanksgiving one of the few holidays that Japan and the U.S. share, it’s a holiday that brings families together to reflect on what’s been accomplished, and to share insight into the future. We've been waiting for just …

Announcing HTTP Git Beta Support Upgrade

Of the many Platform-as-a-Service innovations Heroku has contributed in its seven year existence, perhaps the most iconic is git push heroku master. Today we’re announcing a significant upgrade to Heroku’s Git implementation: Beta support for Git’s HTTP transport.

HTTP Git has some notable advantages over traditional SSH Git. Instead of relying on port 22 (often blocked by firewalls) HTTP Git runs on port 443, the same port used for secure web requests.

Benchmarking Rack Middleware and Improved Speed

Performance is important, and if we can’t measure something, we can’t make it fast. Recently, I’ve had my eye on the ActionDispatch::Static middleware in Rails. This middleware gets put at the front of your stack when you set config.serve_static_assets = true in your Rails app. This middleware has to compare every request that comes in to see if it should render a file from the disk or return the request further up the stack. This post is how I was able to benchmark the middleware and give it a crazy speed boost.

Django and Node together on Heroku

[Heroku Connect] [heroku_connect] is written primarily in Python using Django. It's an add-on and a platform app, meaning it's built on the Heroku platform. Part of our interface provides users with a realtime dashboard, so we decided to take advantage of socket.io and node.js for websocket communication. But like all Heroku apps, only one type of dyno can serve traffic. This left us with two choices: manage 2 apps, each with its own repo, and carefully consider when and how we deployed them, or find a way to serve both node and Django traffic from the same app.
