Ruby 2.1.0 in Production: known bugs and patches

Last week, we upgraded the github.com rails app to ruby 2.1.0 in production.
While testing the new build for rollout, we ran into a number of bugs. Most of
these have been fixed on trunk already, but I've documented them below to help
anyone else who might be testing ruby 2.1 in production.

@naruse I think we should backport these patches to the ruby_2_1 branch and
release 2.1.1 sooner rather than later, as some of the bugs are quite critical.
I'm happy to offer any assistance I can to expedite this process.

When applying Rails upgrades on WiseCash, I want to make sure I review the commits to spot potential regressions. This RSpec spec warns me when I'm upgrading at any time (even tired, where you might forgot to do so).

Your Vision

What is a vision?

Your vision answers the question "What do I want?" A clear vision help you communicate why you're here and what impact you're going to have.

Your vision should be aligned with the company vision, with your manager's V2MOM, and it should be personal. It should be an honest reflection of your own vision for your own work.

If you manage a team, it should be reflective of the purpose of the team and your collective impact.

Here is the little rake task I use to create new posts for the WiseCash jekyll-based blog.

To use, just run:

rake blog:new["Your Blog Post Title"]

Do nothing. All files in this dir are eager loaded in production and lazy loaded in development by default.
