• Is Google 2-Step Authentication a good thing?

After all the cracking stories in the news of late, I decided to turn on Google’s 2-step authentication. It’s a little annoying to wait for a 6-digit code to arrive on my cell phone when I want to log in, but it beats losing my account to the forces of evil.

Any warnings or experiences, good or bad?

Response: Most everyone agrees: yes, this is good, use it.

• $0 – $4 in Chrome

You can reference the 4 most recently selected elements from the Elements panel via these variables.

• Bundler.with_clean_env

When you shell out from your ruby script and run the “bundle” command, it will bundle within the context of your script’s Gemfile (even if you cd first to another directory with a different Gemfile).

If you need to shell out and bundle outside the context of your script’s bundle, use Bundler.with_clean_env. For example:

Bundler.with_clean_env do
  `cd /some/other/bundled/project  && bundle`
end

We ran into a need for this on LicenseFinder – we wrote an integration test suite that bootstraps a bundled project, adds dependencies with various licenses to it, then tests the output of license finder on the project.

Lastly, in an unusual meetup twist,recruiting [for junior developers] is welcome!

Interestings

• CanCan, condition hashes, and index actions

If you have something like:

`can :manage, Group, memberships: { user_id: user.id }`

and:

`class Group < AR::Base
has_many memberships
end`

you will get duplicate Groups in index action’s @groups ivar when you load_and_authorize (sic) :group as CanCan will do an SQL join of the groups and memberships table.

The solution for us was to use a block and populate the @groups ivar ourselves in the action.

• Ruby Gotcha: Extending non-existent class displays confusing error message

class Foo < DontExist
end

describe Foo
it “works” do
Foo.new
end
end

this raises:

uninitialized constant Foo (NameError)

very confusing to say the least. I would have expected the NameError to show that DontExist didn’t exist.
