• Experiment: Use RSpec Expectation Syntax

    A few months ago, the RSpec team announced the new expectation syntax. In the simplest form, the old way of saying:

  • 2014 RubyConf - San Diego

    Better late, than never: Last November I attended RubyConf for the first time. This year it was in sunny San Diego, which I happen to call home.

  • The REPL: Issue 6 - January 2015

    The REPL is a monthly feature in which I pick my favorite content from around the web, read, but not necessarily published, in the last month. Most of it is technology related.

    Suspicions of nil

    In her usual eloquent and clear way, Sandi Metz explores the issue with passing nil around as a return value from other objects. She shows a few of the pitfalls and type checking necessary to deal with the complexity. I’m looking forward to the promised sequel, billed to explore the Null Object pattern.

    Command-line tools can be 235x faster than your Hadoop cluster

    Adam Drake explores traditional Unix tools to analyze a large data set. Using cat, find, xargs and awk he shows that performance can be much better than that used by a Hadoop cluster. The comparison is based on results from another post, which I could not find, since the link seems to have gone away. Nonetheless, I think the the point is made abundantly: Before jumping on the latest shinny big-data thing, it’s probably a good idea to try the tools already installed in your server.

    Myron Marston’s Response To Tenderlove

    Tenderlove posted a review with his experience with MiniTest and RSpec. Myron responded to some of the issues addressed. I found both articles good reads. I have used both frameworks extensively and I am personally partial to RSpec. However, I applaud Tenderlove and Myron for their posts and the decorum which they exhibited. It is quite common for online back and forth to descend into personal insults quite fast. This is not the case. In the course of the discussion, I also learned a thing or to about both frameworks.

    Pairing with Junior Developers

    Sara Mei writes an excellent piece about how senior developers can make the most out of pairing with junior ones, with better results for both developers. I personally don’t pair at work all the time, but I found that most of the content is applicable not only to pairing, but working with junior developers in general. As with most things, you get more out of it if you are dedicated and mindful.

  • Stagnation

    Dependency management in Ruby, is almost universally done with Bundler. It provides an easy way to declare other Ruby dependencies in your application and install them on demand. It manages the explicit dependencies you tell it about in your Gemfile and also resolves the transitive dependencies, those that you do not specify directly, but are declared by the dependencies themselves.
