Interesting Things

• A few projects are using parallel_test to speed up their tests/specs. One project has had the best results by running one less parallel spec than the number of cores on the machine, unless of course you only have one core.

• Another team discovered an odd bug in RubyMine where they could not click-through “require spec” or run specs if their project had code in vendor/plugins that extended ActiveRecord::Base. Here is the RubyMine ticket they filed.

• Finally, it looks like a Linux machine running Ruby 1.8.6 patch 287 had rounding errors when using the ActiveSupport helpers for 2.days.ago. They fixed the issue by upgrading to Ruby 1.8.7
