Restmod creates objects that you can use from within Angular to interact with your RESTful API.

The The U.S. Digital Services Playbook is pretty amazing (context).

DevDocs combines multiple API documentations in a fast, organized, and searchable interface.

Pretty awesome project. You can select multiple docs to be searched simultaneously, offline in your browser. Supports OpenSearch, so you can hit Tab in your Chrome and search your downloaded docs.

See the solution on Ask Different (same answer found here).

Inspiring collection of color tones.

When you have an Angular directive that transcludes content, you might want to do something in case there is no content inside your element, like showing some default content.

Unfortunately, you can not do something like <span ng-transclude>default goes here</span>. Angular will always empty that element's text, even if there is nothing to transclude.

But you can use your directive's link function. Here's some CoffeeScript for you:

    @app.directive 'myStuff', [->
      restrict: 'E'
      transclude: true
      
      te...

Directly from the MySql docs:

There are three likely causes for this error message.

Usually it indicates network connectivity trouble and you should check the condition of your network if this error occurs frequently. If the error message includes during query, this is probably the case you are experiencing.

Sometimes the during query form happens when millions of rows are being sent as part of one or more queries. If you know that this is happening, you should try increasing net_read_timeout from its default of 30 seconds to 60 s...

Great gem to consume RSS feeds. I was missing some features on Ruby's RSS::Parser that I found in Feedjira:

• Speed
• Does not break on slightly malformed RSS feeds (like a missing length attribute on an <enclosure> tag on gizmodo.de's feed)
• It automatically resolves Feedburner-mangled URLs (hooray!)

The GitHub project has only a minimalistic readme. You can find its documentation on their homepage.

You know each_with_index from arrays:

    ['hello', 'universe'].each_with_index do |value, index|
      puts "#{index}: #{value}"
    end
    # 0: hello
    # 1: universe

This also works on hashes. However, mind the required syntax:

    { hello: 'universe', foo: 'bar' }.each_with_index do |(key, value), index|
      puts "#{index}: #{key} => #{value}"
    end
    # 0: hello => universe
    # 1: foo => bar

The reason is that each_with_index yields 2 elements to the block, and you need to deconstruct the first el...

So you erased a whole day's work? There is hope! The linked article tells how to recover from an accidental git reset --hard.

You will need to install GNU find utils as described in this SO post.

In Cucumber, scenario outlines help avoiding tests that are basically the same, except for a few variables (such as different inputs). So far, nothing new.

The problem

Now what if your test should (or should not) do something, like filling in a field only for some tests?

    Scenario Outline: ...
      When I open the form
        And I fill in "Name" with "<name>" # <= we want to do this only occasionally
      Then everybody should be happy
      
    Examples:
      | name  |
      | Alice |
      | Bob   |

You could o...

So you have placed a breakpoint somewhere and now want to dig around, but not even inspecting variables is working:

(rdb:3) @order_item
*** Unknown command: "@order_item".  Try "help".

The reason is, you must tell the debugger to evaluate your expression. One workaround is to call irb to open an irb session at your breakpoint. Resume by sending Ctrl+D twice or by returning to the outer irb with "exit" and then continuing with "c".

However, the native debugger command for your issue is eval (or its shorter alias `e...

Amazing guide how to divide a ball of Javascript spaghetti distinct separate layers (model, view, controller, backend adapter).

It does not use a Javascript framework.

Parses URLs of social networks to extract IDs or screen names.

It does not get confused by child routes: you may also pass URLs like a user's twitter photo stream and the gem will extract their twitter ID .

Note that it just parses URLs, and does nothing magic like looking up IDs when the URL contains only a screen name (e.g. the Instagram API requires you to send the user ID almost always while you at first only know their screen name).

Previously the assets group existed to avoid unintended compilation-on-demand in production. As Rails 4 doesn't behave like that anymore, it made sense to remove the asset group.

While RSpec 1 and 2 decided that specs inside spec/model are model specs, and those inside spec/features are feature specs (and so on), RSpec 3 will no longer do that by default.

This will result in errors such as missing routing helpers, etc.

There are 2 ways to fix this:

• Explicitly set the type on each spec. For example:

  describe '...', type: 'feature' do
    # ...
  end
  

• Add this to your spec_helper.rb (inside the RSpec.configure block) to restore the old behavior:

  ...

Run this command to list the authors of the most recent commit of each branch:

When you don't only have a favicon.ico in your project but also PNGs of different sizes and backgrounds, you should test if all those files are actually reachable.

Here are a few selectors to get you started:

    'link[rel~="icon"]' # regular ones, matches "shortcut icon" and "icon"
    'link[rel="apple-touch-icon"]' # iOS
    'meta[content][name="msapplication-TileImage"]' # IE11
    'meta[content][name^="msapplication-square"]' # IE11

Spreewald 1.1.0 drops the be_true and be_false matchers in order to be RSpec 3 and Ruby 2 compatible. For backward compatibility, these matchers are replaced with == true and == false.

Note the slightly more changed semantics of the update.
