People frequently use lines of code as a metric. How many times have you heard someone say, “it’s only 10 lines?” or “This class is almost 200 lines?” Have you ever heard somebody boast that they could write something in fewer lines of code? Do you talk about your test to code ratio?

A great article explaining a bit in depth of how Ruby code is translated to native machine code via JVM.
Great article with source code examples.
Convert Ruby 1.8 to 1.9 hash syntax
In vim, for an entire file:
:%s/:\([^ ]*\)\(\s*\)=>/\1:/gIn the shell, for an entire project:
perl -pi -e 's/:([\w\d_]+)(\s*)=>/\1:/g' **/*.rbNow, instead of those old-school hashes like this:
get '/', :agent => MOBILE_BROWSERS doYou’ll have new-school hashes like this:
get '/', agent: MOBILE_BROWSERS do

His articles are good explaining Rails core codes. Check it out if you want to dig in deeper into Rails core.
He writes about commit messages, the reason behind them and some insights or opinions regarding these code commits.
The concept of code gardening makes Rails organically grow. There are similarities between our codes and our gardens. Maybe by looking at this similarity we will better ourselves as coders.
Learning from the Masters is definitely a series of articles worth following. Check it out.
