tmux-vim integration to transparently switch between tmux panes and vim split windows

I use tmux splits (panes). Inside one of these panes there's a Vim process, and it has its own splits (windows).

In Vim I have key bindings C-h/j/k/l set to switch windows in the given direction. (Vim default mappings for windows switching are the same, but prefixed with C-W.) I'd like to use the same keystrokes for switching tmux panes.

An extra goal that I've solved with a dirty hack is to toggle between last active panes with C-\.

Here's how it should work:

Ruby 2.0 CA cert issue fix
# If you're having cert issues on ruby 2.0.0-p0, the issue is most likely that ruby can't
# find the required intermediate certificates. If you built it via rbenv/ruby-build, then
# the certs are already on your system, just not where ruby expects them to be.
# When ruby-build installs openssl, it installs the CA certs here:
~/.rbenv/versions/2.0.0-p0/openssl/ssl/cacert.pem
# Ruby is expecting them here:
$(ruby -ropenssl -e 'puts OpenSSL::X509::DEFAULT_CERT_FILE')
# Which for me, is this path:

Simple 'database cleaner' approach using `config.around`. Was able to cut down some seconds out of the suite. Thanks to @brandonhilkert

TorqueBox on Heroku

With Heroku's JRuby support you may have already seen that you can run TorqueBox Lite on Heroku. But, that only gives you the web features of TorqueBox. What about scheduled jobs, backgroundable, messaging, services, and caching?

With a small amount of extra work, you can now run the full TorqueBox (minus STOMP support and clustering) on Heroku as well! I've successfully deployed several test applications, including the example Rails application from our Getting Started Guide which has a scheduled job, a service, and uses backgroundable and messaging.

This example uses TorqueBox 3.0.2, but the instructions may work with other TorqueBox versions.

Steps Required

  1. Create a JRuby application on Heroku, or convert an existing application to JRuby. Make sure your application works on JRuby on Heroku before throwing TorqueBox into the mix.
  2. Add th
