chruby: ultra-minimal ruby switcher
chruby is an ultra-minimal alternative to RVM and rbenv. chruby allows one to install rubies into /usr/local/$ruby, /opt/$ruby or ~/.rubies/$ruby, but install gems into ~/.gem/$ruby/$version. Unlike RVM or rbenv, chruby only modifies $PATH, $GEM_HOME and $GEM_PATH, and does not hook cd or rely on shims. chruby is ~80 lines, supports both bash and zsh, and has unit-tests.

Null migration, or What to do when there are too many migrations
Sooner or later, especially in the long-running projects, the number of migrations exceeds any acceptable norms. When they are 50, it is perfectly acceptable. But in really big projects, their number can be up to 500 or even more. Learn what null migration is and how you can use it to reduce the number of ActiveRecord migrations to one.
How to speed up your test suite
When you practice test-driven development, most of the time you need to run only a small number of tests to validate your recent code changes. Unfortunately things change once you start refactoring. Refactoring models implicates your entire application. So in order to keep things from going down the drain, you’ll need to run all (or most of) your tests constantly. And that’s where things get tedious. [more inside]

Check out the first part of what will be a detailed series all about job processing, message queues and how to integrate them into your application.
