Hello Rubyflow, we're the authors of Raptor, a new Ruby web server that's up to 4x faster than Unicorn, and up to 2x faster than Puma/Torquebox. It has taken us a lot of blood, sweat and tears to write, and we're wrapping up for a release in the near future. You can learn more at

How does Rails handle gems?
If you're not sure how Bundler works, the way gems get pulled into Rails might seem a little too magical. How does adding a line to a Gemfile get code into your app? How do Bundler, Rails, and RubyGems work together to make handling dependencies easy?
Here's a preview of a new feature for Intercity. We just launched easy one-click Rails integration for your Digital Ocean Droplets.

Hello, using the beer.db - open public domain brewery, brewpub and beer data - and - of course - Ruby let's you make your own beer map thanks to GeoJSON. See an example beer map for Austria (~200 breweries n brewpubs). The build script geo.rb - still early and rough - but working is just a couple of lines. Cheers. Prost. Kampai.

I just released queue_classic 3.0.2. I you are using it. Please see the upgrade instructions in the README.

I am also working on getting queue_classic to 3.1, with more support for Active Job. It works right now, it could just be a bit better :)

Things like scheduling that had to be done with a gem should be in core soon-ish (there is a PR), ActiveRecord's DB connection will be detected and used by default (can be turned off).

If you would like to help, let me know!

More on all that in this issue:
I found this great blog by Noah Gibbs, to something I've been wording about for a while. Quite often some of my forms get really into the nesting by name="name[1][key1][key2][]", this blog post provides information on how to test it out with IRB so I know exactly what I'm generating.
I just released version 0.2.0 of kibana-rack, a Rack middleware library that embeds Kibana in a Rack application and creates a proxy to Elasticsearch.

After couple of last months of slower development, I decided to take the job of solving all the open issues. While doing that I also rewrote the internals, bringing up some new features, reduced memory usage, robust command-line execution and many bug fixes. You can see the complete changelog here.

The new version brings lots of nice stuff, so I urge you to try it out, and be sure to check out the renewed readme.

Last year I wrote a post about CMS Trap, a trap you fall into when you try to speculate your app's architecture prematurely. It had great success on HN, but didn't reach enough rubyists, and as a rubyist I mainly intended the article for us. This submission is my attempt to rectify this.
After participating (and winning) several hackathons over the years, I’ve come to appreciate how nicely Rails generates prototypes that build and deploy quickly. Hackathon champions will assert that the secret sauce to winning hackathons is building an actual product that has real validation from potential users. This is a hard goal to achieve when everyone is short on sleep and time. Rails will get your app there.

Here are my simple dos and don'ts for creating a winning Rails app at a hackathon... Continue Reading...

There are lots of good places to learn Ruby. But learning isn’t just reading books or watching videos. It’s running head-first into a problem, getting stuck, struggling, getting frustrated, looking things up, having it click, playing around with it, and finally (finally!) getting something working. You have to use the things you learn, or they won’t stick with you. And there are a few great ways I’ve found to do just that.
Cleaning up a Rails routes file
