Coverage tests in Ruby (with rcov) are less strict than in Java (with EMMA), so watch out – 100% coverage is easy to attain but not as meaningful.

A friend who is working primarily in the J2EE technology world (as I was, until early 2006) asked me for a how’s-it-going with respect to Ruby and Rails.
The short version:
– Ruby is fun to program in, as you’ve probably heard
– Rails is over-hyped, but it’s still quite good (definitely not perfect)
– I like the productivity of Ruby on Rails but I wouldn’t call it a silver bullet by any means
– Ruby performance was bad and is getting less bad, and can even be good if you do what the experts say
– The real gem (har har) in the Ruby and Rails space is the community itself

I’ve been listening to the Ruby on Rails Podcast over the last month or so, starting with the first episode from way back in July 2005 and now I’m up to the March 10, 2006 episode with Bruce Tate. There’s a great section in this podcast where Bruce describes the immense amount of information that programmers have to learn in order to approach J2EE.

I started programming in Ruby this week, and so far I like it a lot. From my initial use of Ruby as a backup automation scripting language, here are my thoughts.
You might be wondering, why am I working on backup scripting now? Don’t I have some big project I’m supposed to be working on 24/7? Yes, and actually this work is in the critical path of that project.
My super fast laptop is still away being repaired for a video problem, so I’ve taken a major hit in terms of the resources of my main computer: 90% less MHz, 36% less display area, 50% less memory. In the meantime, I’ve been avoiding tasks that need a lot of CPU or graphics performance and instead working on things that are easier on my old desktop computer.
This week, I decided that I would pause working on the design and implementation of my startup project, until I had really sorted out my server backup and monitoring situation.
