Today we are going to talk about some of the Ruby’s Hash features, which are well documented, but rarely used — parameters of the Hash constructor. In the second part of this article we will take a look at the arguments of the Array class’ constructor.

Here in Scribd we are using Git as primary version control system. We have tons of branches created, merged and destroyed every day. Someday I hope to describe our workflow with Git, but today I want to write about some useful techniques of working with this incredible tool.
It’s implied that you know what is Git itself and how to work with it. Below you can find some advanced tricks, that should be helpful for you (at least they were helpful for me).

I have not posted anything here for a long time. It’s hard to start blogging again, so I will write a short tips and tricks series called “Memo“. Today I’m going to talk about two Ruby gems I’m using in all my Ruby on Rails project: mysql and memcached. Every time I try to install or update those gems on Mac OS X following error occurs:
1 2 3 | Building native extensions. This could take a while... ERROR: Error installing mysql: ERROR: Failed to build gem native extension. |
And then I’m googling on how to install these gems. It’s time simplify my life and post commands here.
