Configuring Netbeans for JRuby

Netbeans is an IDE (Integrated development environment) originally for Java. However version 6.9 (but not 7) can also be used with Ruby and JRuby. Because it's an IDE for Java, Netbeans is ideal for setting up JRuby on Rails projects. And here is how.





  1. First make sure you Download the Java version of Netbeans 6.9.1 or the complete version. It's easier to add Ruby plugins to the Java Netbeans than viceversa.
  2. Install the Ruby plugins to Netbeans.
  3. Create a new project and follow the screen shots below. 














Netbeans comes with it's own bundled version of JRuby (1.5) so go to Manage Ruby versions to set a different version or even a C-Ruby version if you want.
The server needs to be set to Webrick to get the normal Ruby on Rails server.

If you are setting up a JRuby on Rails project make sure you mark the: "Access Database using JDBC"

And like that you have a properly configured Rails file for JRuby, without having to use the "--template" option. Go check the Gemfile and see for your self.

What Medieval Economics can teach us about tariffs.

As a teen, I used to play Dungeons and Dragons (D&D) with my friends. This started an interest in the medieval period that led to me taking a medieval history class in college just to understand the period more. Over the years I've also read great books like " Dungeon, Fire and Sword " about the crusades (I recommend the book) and yet with all that knowledge it wasn't until recently that it occurred to me I had a completely wrong understanding of economics in the Medieval Period. "Viking helmets, sword and footwear" by eltpics is licensed under CC BY-NC 2.0 In my D&D games, players who are adventures battling monsters and creatures would need equipment and on the trips to town, they'd get resupplied with their adventuring necessities. I'd run these moments referencing my imagination of what it must have been and fantasy books I'd read. There be an inn with a raucous bar, a gruffly black-smith, if a city also a weapon and armor sm...

Testing with Cucumber, Sinatra and Capybara

Everything you need to know There are many elements you need to simultaneously learn to do effective testing of your code. Because some of these elements are very simple a lot of explanations just jump over what you need to know and give them up as obvious. Let’s start with a list of the things you need to learn: Gherkin (the language of Cucumber) ——> super easy Capybara (the DSL that controls the browser tests) Rspec (the DSL in which the actual pass/fail tests are written.) None of these are hard. But having to learn all at the same time can seem daunting. But it’s not! It’s easy peasy but takes time. :-/ It took me three days to get a handle on this. And I hope by reading this you’ll get a handle on it much much quicker. Let’s start with Cucumber first. Cucumber Five things you need to know about Cucumber: Cucumber tests are located on a features folder that have plain text files with a .feature extension and written in Gherkin . The .feature files contain t...

Los NiNis & The Slackers

NiNis are the youth segment of the population 16-35 that neither study nor work ( Ni estudian, Ni trabajan). They are the Spanish and Latin-American equivalent of the slacker. They typically live at home with their parents or other family and are sometimes referred to as leeches on family resources. I posit that the NiNis like the slackers before them are mislabeled as lazy by society and incorrectly perceived as leeches or drains on normal society. Slackers were of my generation. Smart people that seemed unable to focus and apply themselves to take work seriously; they spent a lot of their time on seemly wasted hobbies like video games, making videos, or writing blogs (many of which are now rather decent careers). But thinking of them as lazy is wrong. These are people that want to work, sometimes desperately, but they just don't see the point. They're not lazy, just unmotivated. I recently got Jane McGonigal's book 'Reality is Broken' and I agree with her. It is ...
