Gave a shot to the new Bundler 1.4.0RC1 during the weekend and found out it now supports gem installation in parallel. To invoke you need to pass --jobs parameter with number of threads you want it to run – for me the best performance was achieved by specifying the number physical CPU cores.

I've tested on the AppFab app. In my case (CPU with 2-core i7 with HT) the speedup was 50%. I've also tried with a number greater than the number of physical cores but the performance was 15%-20% worse.

If you have a commit and you want to see in what branches is is included, you have to write this:

git branch -r --contains [COMMIT-SHA]

-r is for remote

wkhtmltopdf hangs on mac during cucumber unless we click on it. The main reason is with the version we use which is 0.11.0_rc1 and in out app/bin we have another version and it is a known issue with these versions. The fix is to go to 0.9.9, to downgrade the version we installed earlier using brew:

* brew uninstall wkhtmltopdf
* brew update
* brew versions wkhtmltopdf
* if you see output like 
*         `0.9.9    git checkout 6e2d550 /usr/local/Library/Formula/wkhtmltopdf.rb`
           then `cd /usr/local`

When simply checking equality or truthiness then
Instead of:
it "should have role set to admin" do
@user.role.should eql('admin')
end

it "should be valid" do
  @user.valid?.should be_true
end

Do:
it { @user.role.should eql('admin') }
it { @user.valid?.should be_true}

Try to stick to one expectation per test block, diverge in exceptional circumstrances, so instead of:
describe "#some_method" do
before(:each) do
@object = Class.new
end

   it "should have attributes set" do

Go to lib folder and use bundler to generate main files for a gem:

$ bundle gem test_gem

      create  test_gem/Gemfile
      create  test_gem/Rakefile
      create  test_gem/LICENSE
      create  test_gem/README.md
      create  test_gem/.gitignore
      create  test_gem/test_gem.gemspec
      create  test_gem/lib/test_gem.rb
      create  test_gem/lib/test_gem/version.rb
Initializating git repo in /path/to/webapp/HouseTrip-Web-App/lib/test_gem

cd in to created directory

$ cd test_gem/

Regularly, but at least before merging your feature branches, rebase them to get rid of "fix typo" and "wip" commits.

Getting rid of unnecessary commits

Let's say you do a git rebase -i HEAD~~~~ and have this commit history:

pick 1d1e1f My Feature
pick 2d2e2f My Feature - wip
pick 3d3e3f My Feature - fix typo
pick 4d4e4f My Other feature

Change it to use fixup for those commits that should be merged into the one before ...

This is how we name branches :

• <team>/<story>-<id> (features)
• fix/<team>/<story>-<id> (bugs)

story is an dash-delimited version of the story name, and id the Pivotal story number.

Examples :

• supply/belvilla-naming-1234567
• fix/tripadvisor/property-syncing-3256674
• integration/geo/boroughs
