The problem is that you&#39;re currently calling `ceil` on `30.to_f`. Here&#39;s how Ruby evaluates it:

    (67)/(30.to_f.ceil)
    # .ceil turns the float into an integer again
    (67)/(30.0.ceil)
    # and now it&#39;s just an integer division, which will be 2
    67/30 # = 2

To solve this, you can just add parenthesis:

    puts (67/30.to_f).ceil  # = 3

I am trying to connect to MSSQL 2012 using NodeJS with the [mssql](https://patriksimek.github.io/node-mssql/) connection interface. 

When attempting to connect I get the following error:

    { [ConnectionError: Failed to connect to localhost:1433 - connect ECONNREFUSED]
      name: &#39;ConnectionError&#39;,
      message: &#39;Failed to conncet to localhost:1433 - connect ECONNREFUSED&#39;,
      code: &#39;ESOCKET&#39; }

Any ideas on how to fix this?

I am new to Elasticsearch and am currently working on implementing a `geo_distance` filter for searching. As of now my index has the following mapping (I&#39;ve removed some fields):

    {
    advert_index: {
       mappings: {
          advert_type: {
             properties: {
                __v: {
                   type: &quot;long&quot;
                },
                caption: {
                   type: &quot;string&quot;
                },
                category: {
                   type: &quot;string&quot;
                },
                **location: {
                type: &quot;long&quot;
                },**
  
             }
          }
       }
    }

The geo_distance field is going to be implemented on the location field, where an example instance looks like this: 

    &quot;location&quot;: [
                   71,
                   60
                ],
I.e. is on geoJSON format `[lon, lat]`. 

I understand that I will have to update my index so that the location field is of type `geo_point`, as described in the documentation (&lt;a href=&quot;http://www.elasticsearch.org/guide/en/elasticsearch/reference/current/mapping-geo-point-type.html&quot;&gt;mapping-geo-point&lt;/a&gt;). It seems like I have to drop the index and create a new one, but I am not able to do this. 

Am I on the right track? I would greatly appreciate it if anyone could help me with how I could create a new index or update my existing one with the correct data type. 

Many thanks!

I feel like a crazy person. I&#39;d like to round all fractions up to the nearest whole number.

For example, 67/30 = 2.233333333334. I would like to round that up to 3. If the result is not a whole number, I never want to round down, only up.

This is what I&#39;m trying:

    puts 67/30.to_f.ceil

Here are examples of what I&#39;m looking for:

 - 67/30 = 3
 - 50/100 = 1
 - 2/2 = 1

Any ideas? Thanks much!

I have recently reinstalled ruby 2.1.2 like so since I wanted to install a gem (`ruby-debug-ide`)

    sudo rvm reinstall 2.1.2 --disable-binary --with-gcc=gcc-4.2

Since then, I can&#39;t load my console using `bundle exec rails c`
due to the following error :

    /Users/ohad/.rvm/gems/ruby-2.1.2@aaa/gems/activesupport-3.2.11/lib/active_support/dependencies.rb:251:in `require&#39;: dlopen(/Users/ohad/.rvm/rubies/ruby-2.1.2/lib/ruby/2.1.0/x86_64-darwin13.0/readline.bundle, 9): Library not loaded: @@HOMEBREW_PREFIX@@/opt/readline/lib/libreadline.6.dylib (LoadError)
      Referenced from: /Users/ohad/.rvm/rubies/ruby-2.1.2/lib/ruby/2.1.0/x86_64-darwin13.0/readline.bundle

Tried `brew uninstall readline` and `brew install --build-from-source readline` which worked but didn&#39;t solve my problem.

Running Rails 4.1.4 with the latest releases of haml, haml-rails, sass, and bootstrap-sass. For a user display, my HAML is as such:

    .tutors-listing
        .row
          - @users.each do |tutor|
            .col-xs-12.col-md-3
              .row.tutor
                .col-xs-offset-1.col-xs-4.col-md-12
                  = image_tag tutor.photo, :class =&gt; &#39;img-responsive img-circle tutor-photo&#39;
                  %h4.tutor-name
                    = tutor.first_name
 
                 %p
                    teaches
                 %strong.tutor-skills
                   = tutor.teachables

However, this markup results in the following glitch:
![Irregular column wrapping][1]
![More irregular column wrapping][2]

I&#39;m hoping somenone can devine what&#39;s wrong here. At the medium breakpoint, there should be 4 columns evenly.

`[2, 6, 13, 99, 27].include?(2)` works well for checking if the array includes one value. But what if I want to check if an array includes any one from a list of multiple values? Is there a shorter way than doing `Array.include?(a) or Array.include?(b) or Array.include?(c) ...`?

Array.include? multiple values

I&#39;m on Rails 4 and have noticed some of my RSpec tests are failing because some of my test refactorings use a before filter (presumably because of transactions). This post describes a similar issue: 

https://stackoverflow.com/questions/16268728/rails-test-database-not-clearing-after-some-runs

In lieu of using the DatabaseCleaner gem, is there a rake command to clear out the test database?  I believe `rake db:test:prepare` is deprecated in Rails 4. Also, if before transactions like

    `post :create, user: Fabricate.attributes_for(:user)`

are persistent, is there an alternative way of refactoring to avoid the need to manually clear out the test database?

I cannot understand why the Cocoapod is unable to find the pod specification I created when I run `pod install`. Could someone help me solve this trouble?

I&#39;m defining a subspec in my library podspec file like this:
    
    s.subspec &#39;mysubspec&#39; do |c|
      c.dependency &#39;ABC&#39;,&#39;1.0.0&#39;
    end 

This dependency ABC is listed in the library Podfile:

    pod &#39;ABC&#39;, :git =&gt; &#39;git@github.com:myrepo/Podspecs.git&#39;, :branch =&gt; &#39;xyz&#39;

The Podspec file `ABC.podspec` in the branch xyz of myrepo/Podspecs seems like this:

    Pod::Spec.new do |s|
      s.name         = &quot;ABC&quot;
      s.version      = &quot;1.0.0&quot;
      s.source       = { :git =&gt; &quot;git@github.com:myrepo/Podspecs.git&quot;, :branch =&gt; &quot;xyz&quot; }
    end

The error is `[!] Unable to find a specification for ABC (= 1.0.0)`

**Solution:**  import the pod ABC before importing the subspec and add the tag to the podspec.
