I use RSpec in all my projects. It’s really hard to overemphasize how helpful it is and how much easier becomes your life if you have good specs coverage. But its outstanding flexibility enables many ways to make your specs awful: horribly slow, over-bloated, even non-readable sometimes. I do not want to teach you BDD and RSpec here, but instead I will give you some ideas how to improve your specs quality and increase efficiency of your BDD workflow.

Last few weeks Thoughtbot publish lots of really stupid (gsub syntax manual; are you serious?) articles (WTF is Best practice: index every boolean column) in their blog. And yesterdays article about tailing your Rails log is the absolute leader, it’s freaking awesome. Hey guys, I’m waiting for other articles in this series: “@ in attribute names, what does it mean?”, “if-then-else statement usage best practices for Ruby on Rails senior developers”, “how to install a gem”.
Hey robots, we have a reply to your outstanding articles: A wonderful way to list your project files. Please read it carefully, you definitely will find something useful for you! Thanks to @labria for his great exploration.

Today my friend asked me to help him with an unexpected behavior of Ruby’s Hash.uniq method. Here is an example:
1 2 3 4 5 6 | [{"id"=>667824693}, {"id"=>667824693}].uniq # => [{"id"=>667824693}, {"id"=>667824693}] [{"id"=>66782469}, {"id"=>66782469}].uniq # => [{"id"=>66782469}] [{"id"=>6678246931}, {"id"=>6678246931}].uniq # => [{"id"=>6678246931}] |

In Scribd we have tons of analytics data generated daily that should be somehow processed. Currently we use MySQL to store all this stuff, but that is not the best option for logging lots of data. So we’ve decided to try some more specialized tools, which could help us to store and process our data. The most interesting thing which could simplify analytics data collecting was Scribe. As it turned out, installation process is not so simple as expected so here you will find a few steps manual on how to install Scribe on a developer machine.
